Science events (Einstein, getting research to patients, sleep, and art/science) in Vancouver (Canada), Jan. 23 – 28, 2016

There are five upcoming science events in seven days (Jan. 23 – 28, 2016) in the Vancouver area.

Einstein Centenary Series

The first is a Saturday morning, Jan. 23, 2016 lecture, the first for 2016 in a joint TRIUMF (Canada’s national laboratory for particle and nuclear physics), UBC (University of British Columbia), and SFU (Simon Fraser University) series featuring Einstein’s  work and its implications. From the event brochure (pdf), which lists the entire series,

TRIUMF, UBC and SFU are proud to present the 2015-2016 Saturday morning lecture series on the frontiers of modern physics. These free lectures are a level appropriate for high school students and members of the general public.

Parallel lecture series will be held at TRIUMF on the UBC South Campus, and at SFU Surrey Campus.

Lectures start at 10:00 am and 11:10 am. Parking is available.

For information, registration and directions, see :

January 23, 2016 TRIUMF Auditorium (UBC, Vancouver)
1. General Relativity – the theory (Jonathan Kozaczuk, TRIUMF)
2. Einstein and Light: stimulated emission, photoelectric effect and quantum theory (Mark Van Raamsdonk, UBC)

January 30, 2016 SFU Surrey Room 2740 (SFU, Surrey Campus)

1. General Relativity – the theory (Jonathan Kozaczuk, TRIUMF)
2. Einstein and Light: stimulated emission, photoelectric effect and quantum theory (Mark Van Raamsdonk, UBC)

I believe these lectures are free. One more note, they will be capping off this series with a special lecture by Kip Thorne (astrophysicist and consultant for the movie Interstellar) at Science World, on Thursday, April 14, 2016. More about that when at a closer date.

Café Scientifique

On Tuesday, January 26, 2016 at 7:30 pm in the back room of The Railway Club (2nd floor of 579 Dunsmuir St. [at Seymour St.]), Café Scientifique will be hosting a talk about science and serving patients (from the Jan. 5, 2016 announcement),

Our speakers for the evening will be Dr. Millan Patel and Dr. Shirin Kalyan.  The title of their talk is:

Helping Science to Serve Patients

Science in general and biotechnology in particular are auto-catalytic. That is, they catalyze their own evolution and so generate breakthroughs at an exponentially increasing rate.  The experience of patients is not exponentially getting better, however.  This talk, with a medical geneticist and an immunologist who believe science can deliver far more for patients, will focus on structural and cultural impediments in our system and ways they and others have developed to either lower or leapfrog the barriers. We hope to engage the audience in a highly interactive discussion to share thoughts and perspectives on this important issue.

There is additional information about Dr. Millan Patel here and Dr. Shirin Kalyan here. It would appear both speakers are researchers and academics and while I find the emphasis on the patient and the acknowledgement that medical research benefits are not being delivered in quantity or quality to patients, it seems odd that they don’t have a clinician (a doctor who deals almost exclusively with patients as opposed to two researchers) to add to their perspective.

You may want to take a look at my Jan. 22, 2016 ‘open science’ and Montreal Neurological Institute posting for a look at how researchers there are responding to the issue.

Curiosity Collider

This is an art/science event from an organization that sprang into existence sometime during summer 2015 (my July 7, 2015 posting featuring Curiosity Collider).

When: 8:00pm on Wednesday, January 27, 2016. Door opens at 7:30pm.
Where: Café Deux Soleils. 2096 Commercial Drive, Vancouver, BC (Google Map).
Cost: $5.00 cover (sliding scale) at the door. Proceeds will be used to cover the cost of running this event, and to fund future Curiosity Collider events.

Part I. Speakers

Part II. Open Mic

  • 90 seconds to share your art-science ideas. Think they are “ridiculous”? Well, we think it could be ridiculously awesome – we are looking for creative ideas!
  • Don’t have an idea (yet)? Contribute by sharing your expertise.
  • Chat with other art-science enthusiasts, strike up a conversation to collaborate, all disciplines/backgrounds welcome.
  • Want to showcase your project in the future? Participate in our fall art-science competition (more to come)!

Follow updates on twitter via @ccollider or #CollideConquer

Good luck on the open mic (should you have a project)!

Brain Talks

This particular Brain Talk event is taking place at Vancouver General Hospital (VGH; there is also another Brain Talks series which takes place at the University of British Columbia). Yes, members of the public can attend the VGH version; they didn’t throw me out the last time I was there. Here’s more about the next VGH Brain Talks,

Sleep: biological & pathological perspectives

Thursday, Jan 28, 6:00pm @ Paetzold Auditorium, Vancouver General Hospital

Speakers:

Peter Hamilton, Sleep technician ~ Sleep Architecture

Dr. Robert Comey, MD ~ Sleep Disorders

Dr. Maia Love, MD ~ Circadian Rhythms

Panel discussion and wine and cheese reception to follow!

Please RSVP here

You may want to keep in mind that the event is organized by people who don’t organize events often. Nice people but you may need to search for crackers for your cheese and your wine comes out of a box (and I think it might have been self-serve the time I attended).

What a fabulous week we have ahead of us—Happy Weekend!

#1 The Examination of Bill Murray’s Meatball and the Evolution of Nerds: SummerCamp 101

Jeff Willis

What does Bill Murray, Meatballs and Nerd Evolution have in common? Summer Camp! Buckle your seat belt, open your cranium and roll up your sleeves as we take an introspective and hilarious indepth [sic] journey of relating Bill Murray’s movies to the design and flavor of a meatball wrapped up with the birthing of nerds. How can it be? Nerds, camp and Bill Murray…WTF…what the fun!  Jeff Willis is a giant camp geek and ready to share his thesis of the evolution of a nerd through the lens of summer camp. Geeking about camp at Nerd Nite.

Bio: Since 1991, Jeff (aka Willy), has been developing and leading various camps, expeditions and outdoor programs throughout Canada, Japan, Germany and the Arctic. His love of outdoor education coupled with formal training and years of experience in youth and family work led him to create and work at numerous camps such as Camp Fircom, Camp Suzuki and Fireside Avdentures. He is the quintessential camp director – an energetic leader, creating meaningful experiences for campers and having a load of fun along the way!

#2 Ever Wonder about Science Blogging?

Dr. Raymond Nakamura

In this experimental presentation, we are going to develop an outline for a science blog and a cartoon to go with it. At the beginning, I will exploit the curiosity of the audience to develop a topic. In the middle, I will mine the knowledge and perhaps smart phones of the audience to flesh out an outline. And in the end, I will tap into the imagination and humour of the audience to create a related science cartoon. Come see if this experiment blows up in my face and perhaps learn a little about science communication in the process.

Bio: Raymond Nakamura spends most of his time walking the dog, washing dishes, and helping his daughter with homework. As Head of Raymond’s Brain, he creates blog posts for Science World, co-hosts a podcast for the Nikkei National Museum, writes exhibit text and develops educational programs. He is an editor and cartoonist for the Science Borealis Canadian science blog site, an executive for the Lower Mainland Museum Educators group, and author of a picture book called Peach Girl. Twitter stalk him @raymondsbrain.

#3 The Seas Have Eyes

Dr. Greg Gavelis

Gaze into the algae and the algae gaze back into you. Discover why this bizarre statement is true as we learn about the scientific pursuit of a single cell said to have a human-like eye. In this process, we will explore the controversy and lurid details behind a lost branch of evolutionary theory, and perhaps find an answer to the question “Just how did eyes evolve, anyway?”

Bio: Greg Gavelis works at UBC [University of British Columbia], researching evolutionary cell biology. His findings have been featured in the journals Nature and National Geographic online.  In the past, Greg has accrued further nerd points through his Harry Potter themed wedding, collection of magic cards, inhalers and orthodontia, and was once hospitalized by a squirrel.

Online tickets are still available, as of 1740 PST on Jan. 18, 2016.

#BCTECH: preview of Summit, Jan. 18 – 19, 2016

It is the first and it is sold out. Fear Not! I have gotten a press pass so I can investigate a bit further. In the meantime, #BCTECH Summit 2016 is a joint venture between the province of British Columbia (BC, Canada) and the BC Innovation Council (BCIC), a crown corporation formerly known as the Science Council of British Columbia.  A Jan 6, 2016 BCIC news release tells the story,

With less than two weeks to go and tickets 95% sold out, world-renowned keynote speakers will reinforce technology’s increasing economic and social impact to more than 2,000 people during B.C.’s first #BCTECH Summit on Jan. 18 & 19, 2016.

With Microsoft confirmed as the title sponsor, the summit will feature numerous dynamic keynote speakers:

  •  Ray Kurzweil, inventor, futurist—described as “the restless genius”, with predictions that will change how people think about the future.
  •  Andrew Wilson, CEO, Electronic Arts—named one of the top people in business by Fortune magazine.
  •  T.K. “Ranga” Rengarajan, corporate vice-president, Microsoft—will explore how technology and the cloud is empowering Canadians and changing how we do business and interact in the digital world.
  •  Elyse Allan, president and CEO, GE Canada—named one of the 25 most powerful people in Canada.
  •  Eric Ries, pioneer of the Lean Startup movement—a new approach to business that’s being adopted around the world; changing the way companies are built and new products are launched.

In addition, panel discussions featuring B.C. business leaders and global thought leaders will explore the latest trends, including fintech, cleantech, big data and cyber security.

A technology showcase will feature B.C.’s most innovative technology at work, including robots, 3D printing and electric cars. A new exhibit, the 4D Portal, will take delegates on a journey of B.C. tech, from deep below the earth’s surface into outer space.

More than 500 high school and post-secondary students will also take part in the summit’s career showcase featuring speakers and exhibitors sharing the latest information about technology as a career choice that pays, on average, 60% more than the B.C. average.

As part of the career showcase, nearly 200 high school students will participate in a coding camp and learn basic coding skills. The coding camp will also be offered via live webcast so schools throughout the province can participate.

A key component of the summit will profile venture capital presentations made by 40 promising small- to medium-sized B.C. companies aiming to attract investors and proceed to the next stage of development.

B.C.’s technology sector, a key pillar of the BC Jobs Plan, is consistently growing faster than the economy overall. Its continued growth is integral to diversifying the Province’s economy, strengthening B.C.’s business landscape and creating jobs in B.C. communities.

The new $100 million venture capital BC Tech Fund, announced Dec. 8, 2015, is the first pillar of the comprehensive #BCTECH Strategy to be released in full at B.C.’s first #BCTECH Summit, Jan. 18 – 19, 2016. The conference is presented by the B.C. government in partnership with the BC Innovation Council (BCIC).

  •  B.C.’s 9,000 technology companies combined generated $23.3 billion in revenue in 2013.
  •  New technology companies are emerging at increasing rates throughout the province. In 2013, there was an addition of more than 700 new technology companies in B.C., an increase of 8% over the prior year.

I’m not a big fan of Kurzweil’s but the man can sell tickets and, in days past, he did develop some important software. You can find out more about him on his website and critiques can be found here on Quora, as well as, a thoughtful Nov. 5, 2012 piece by Gary Marcus for the New Yorker about Kurzweil’s latest book (“How to Create a Mind: The Secret of Human Thought Revealed”).

As for me, I’m most interested in the trade show/research row/technology showcase. Simon Fraser University sent out a Jan. 14, 2016 news release highlighting its participation in the trade show and summit (weirdly there was nothing from the other major local research institution, the University of British Columbia),

Simon Fraser University is a gold sponsor of the #BCTECH Summit a new two-day event presented by the B.C. government and the BC Innovation Council to showcase the province’s vibrant technology sector

 

Simon Fraser University will be highly visible at the inaugural #BCTECH Summit taking place on January 18-19 at the Vancouver Convention Centre.

 

In addition to technology displays from student entrepreneurs at the SFU Innovates booth, SFU research will be featured at both the Technology Showcase and Research Row. [emphasis mine] SFU representatives will be on hand at the Career Showcase to speak to secondary and post-secondary students who are interested in the industry. And several investment-ready companies affiliated with SFU will be pitching to elite investors.

 

During the summit, entrepreneurs, investors, researchers, students and government will explore new ideas on how to gain a competitive advantage for B.C. The event will spark discussion on directions for the province’s rapidly developing high tech sector, while several streams will illustrate and share new innovations.

 

“This event provides us with an opportunity to showcase how SFU students, faculty, alumni and client companies are stimulating innovation and creating jobs and opportunities for British Columbia,“ says SFU Vice-President Research Joy Johnson. “And it highlights the work we’ve been doing to inspire, develop and support impact-driven innovation and entrepreneurship through SFU Innovates.”

 

SFU Innovates was launched in October to synergize and strengthen the university’s activities and resources related to community and industry engagement, incubation and acceleration, entrepreneurship and social innovation.

 

Johnson will introduce the summit’s keynote address by Eric Ries, Silicon Valley entrepreneur and author of The Lean Startup, on How today’s Entrepreneurs Use Continuous Innovation to Create Radically Successful Businesses, on Jan. 18 [2016] at 10:45 a.m.

Students and delegates will also have the opportunity to explore the various research and technology showcases.

 

Backgrounder: SFU Innovations at #BCTECH Summit

 

Research Row

 

4D LABS will showcase how it has helped B.C.’s academic and industry tech clients turn their ideas into innovations. The facility has been instrumental in bringing numerous ideas out of the lab and into the marketplace, advancing a diverse range of technologies, including fuel cells, batteries, biosensors, security devices, pharmaceutical delivery, MEMS, and many more. As B.C.’s premier materials research institute, the open-access, $65 million state-of-the-art facility has helped to advance nearly 50 companies in the local tech sector.

 

• SFU researchers led by JC Liu of the Faculty of Applied Sciences will display their cloud gaming platform, Rhizome, utilizing the latest hardware support for both remote servers and local clients. The platform takes the first step towards bridging online gaming systems and the public cloud, accomplishing ultra-low latency and resulting in a low power consumption gaming experience. Their demo shows that gaming over virtualized cloud can be made possible with careful optimization and integration of different modules. They will also introduce CrowdNavigation, a complementary service to existing navigation systems that combats the “last mile puzzle” and helps drivers to determine the end of routes.

 

Molescope is a hand held tool that uses a smartphone to monitor skin for signs of cancer. The device is based on research that Maryam Sadeghi conducted during her doctoral studies at SFU and commercialized through her company, MetaOptima Inc., a former SFU Venture Connection client. The product was unveiled at the World Congress of Dermatology in 2015 and is also now available at the consumer level. Molescope enables people to monitor their moles and manage skin health.

 

Technology Showcase

 

• Engineering science professors Siamak Arzanpour and Edward Park will showcase their Wearable Lower Limb Anthropomorphic Exoskeleton (WLLAE) – a lightweight, battery-operated and ergonomic robotic system to help those with mobility issues improve their lives. The exoskeleton features joints and links that correspond to those of a human body and sync with motion. SFU has designed, manufactured and tested a proof-of-concept prototype and the current version can mimic all the motions of hip joints. Researchers anticipate the next generation of this system early this year. The prototype will be live-demoed as an example of a breakthrough innovation.

 

Venture Capital Presentations

 

Several SFU-affiliated companies were selected to present investment pitches to local and international venture capitalists at the summit, including:

 

H+ Technology, creator of Holus, an interactive, tabletop holographic platform that converts any digital content from your tablet, smartphone, PC or Mac into a 360-degree holographic experience. H+ was co-founded by three SFU alumni and was a former client company of the SFU incubator at the Harbour Centre campus.

ORA Scents, a mobile device company created by an SFU Beedie School of Business undergrad student, that is introducing the world’s first app-enabled scent diffuser that enables users to create, control and share personalized scents in real-time. [Sounds like oPhone mentioned in my June 18, 2014 posting.)

 

Also presenting at the VentureLabs area within the BC Accelerator Network Pavilion will be: PHEMI Health Systems, Semios, XCo, U R In Control, TeamFit, Instant, Wearable Therapeutics, V7 Entertainment, ThinkValue, and Aspect Biosystems. Lungpacer Medical and Metacreative, both companies formed around SFU faculty research, will also have exhibits.

 

Prize draws will be held for projects from RADIUS Slingshot ventures The Capilano Tea House & Botanical Soda Co. and Naked Snacks.

I’m particularly interested in what 4D Labs is doing these days. (They used to brand themselves as a nanotechnology laboratory but they’ve moved on to what they see as more sophisticated branding. I’m just curious. Have they changed focus or is it nanotechnology under a new name?)

Science and the new Canadian cabinet

Justin Trudeau, Canada’s new Prime Minister was sworn in this morning (Nov. 4, 2015). He announced his new cabinet which holds 30 or 31 ministers (reports conflict), 15 of whom are women.

As for my predictions about how science would be treated in the new cabinet, I got it part of it right. Navdeep Singh Bains was named Minister of Innovation, Science and Economic Development. I believe it’s the old Industry Canada ministry and it seemed the science portfolio was rolled into that ‘new’ ministry name as I suggested in my Nov. 2, 2015 posting.  (I thought it would be Industry and Science.)  However, there is also a Minister of Science, Kirsty Duncan. This represents a promotion of sorts for the science portfolio since it was previously considered a junior ministry as signified by the  title ‘Minister of State (Science and Technology)’.

It appears science is on the Liberal agenda although how they’re going to resolve two ministers and ministries having science responsibilities should be interesting. At the top level, I imagine it’s going to be split into applied science or commercial science (Innovation) as opposed to basic science or fundamental science (Science). The problem in these situations is that there’s a usually a grey area.

Moving on, if there’s anything that’s needs to be done quickly within the science portfolios, it’s the reinstatement of the mandatory long form census. Otherwise, there’s no hope of including it as part of the 2016 census. This should induce a sigh of relief across the country from the business community and provincial and municipal administrators who have had some planning and analysis problems due to the lack of reliable data from the 2011 census and its mandated, by then Prime Minister Stephen Harper, voluntary long form census.

***ETA Nov. 6, 2015: A day after the cabinet announcement, there was an announcement reinstating the mandatory long form census about which David Bruggeman provides an update  in a Nov. 5, 2015 posting on his Pasco Phronesis blog (Note: Links have been removed),

He [Justin Trudeau] also announced his cabinet, and his government announced that it would restore the mandatory long-form census.  I’ll focus on the cabinet, but the census decision is a big deal, especially with the next one scheduled for 2016. The official list of the top tier Cabinet appointments is online.

The census decision was announced by the new Minister of Innovation, Science and Economic Development, MP Navdeep Bains.  Minister Bains was returned to Parliament in this year’s election, having served previously in Parliament from 2004-2011.  His training is in finance and his non-Parliamentary experience has been in financial analysis.  …

If you have the time, do read David’s post he includes more detailed descriptions of the new ‘science’ cabinet appointees. And, back to the original text of this posting where I highlight two of the ‘science’ appointments.***

As for the two new ‘science’ ministers, Kirsty Duncan and Navdeep Singh Bains there’s this from the Nov. 4, 2015 cabinet list on the Globe & Main website,

Navdeep Singh Bains
[Member of Parliament {MP} for] Mississauga-Malton, Ontario

Innovation, science and economic development

Former accountant at the Ford Motor Company of Canada. Former professor at Ryerson University’s management school. Entered federal politics in Mississauga in 2004.

Kirsty Duncan
[MP] Etobicoke North, Ontario

Science

Medical geographer and former professor at the University of Windsor and University of Toronto. Has been a Liberal MP since 2008.

For those who don’t know, Etobicoke (pronounced e [as in etymology] toh bi coh), is considered a part of the city of Toronto.

There is more information about this new government in the form of a PDF listing the new Cabinet committees and their membership. I’m not sure about the protocol but it would have been nice to see Elizabeth May, MP and leader of the Green Party, listed as a member of the Cabinet Committee on Environment, Climate Change and Energy (there were three petitions asking she be named Environment Minister according to an Oct. 20, 2015 news item by Lisa Johnson for CBC [Canadian Broadcasting Corporation] news online). Perhaps she’ll be on a Parliamentary committee concerned with these issues.

More predictions

Buoyed by my almost successful prognostication, I’m going to add another couple to the mix.

I think there will be the appointment of a Chief Science Advisor (likely answering to the Prime Minister or Prime Minister’s Office) and while some might think Ted Hsu would be a good choice, I suspect (sadly) he would be considered too partisan a choice. A physicist by training, he was a Liberal Member of Parliament and the party’s science and technology critic in the recently dissolved 41st Parliament of Canada from June 2, 2011 to August 15, 2015. However, should Prime Minister Justin Trudeau choose to appoint a Parliamentary Science Officer after appointing a Chief Science Advisor to the government, Hsu might be considered a very good choice given his experience as both scientist and parliamentarian. (As I understand it, a Parliamentary Science Officer, as modeled by the UK system, is someone who gives science advice to Members of Parliament who may request such advice when dealing with bills that contain science policy or require a better understanding of science, e.g. an energy bill, when debating and voting on the measure.)

Justin Trudeau and his British Columbia connection

Amusingly, the University of British Columbia (UBC) is touting the fact that Trudeau graduated from there with an undergraduate degree in Education. From a Nov. 4, 2015 UBC news release (received in my email),

The University of British Columbia congratulates Justin Trudeau, who earned a bachelor of education from UBC in 1998, on becoming Prime Minister of Canada today.

“It is not every day that a UBC alumnus achieves Canada’s highest office,” said Interim President Martha Piper. “As UBC celebrates its Centennial year, Mr. Trudeau’s accomplishment will serve as a prominent marker in the history of our university and count among the highest achievements of our more than 300,000 alumni.”

Trudeau is the first UBC graduate to be elected prime minister and joins fellow alumni prime ministers Kim Campbell (BA’69, LLB’83) and John Turner (BA’49) who were appointed upon securing their party leadership.

UBC would also like to congratulate alumna Jody Wilson-Raybould (LLB’99), who was appointed Minster of Justice and Attorney General of Canada, and all the other cabinet ministers appointed today.

“UBC looks forward to working with Prime Minister Trudeau and his cabinet in the coming months and continuing the strong dialogue UBC has enjoyed with our partners in Ottawa,” said Piper.

This is only amusing if you know that UBC is trying desperately to distance itself from a recent scandal where Arvind Gupta, president, stepped down (July 2015) from his position at the university only one year into his term for reasons no one will disclose. While the timing (the news release was distributed late on a Friday afternoon) and secrecy seemed suspicious, the scandal aspect developed when the chair of the UBC Board of Governors, John Montalbano called a faculty member to complain about a blog posting where she speculated about some of the pressures that may have been brought to bear on Gupta. Her subsequent posting about Montalbano’s phone call and senior faculty response excited media interest leading eventually into an investigation into Montalbano’s behaviour and charges that he was interfering with academic freedom. Recently exonerated (Oct. 15, 2015), Montalbano resigned from the board, while UBC admitted it had failed to support and protect academic freedom. Interesting, non?

Inside-out plants show researchers how cellulose forms

Strictly speaking this story of tricking cellulose into growing on the surface rather than the interior of a cell is not a nanotechnology topic but I imagine that the folks who research nanocellulose materials will find this work of great interest. An Oct. 8, 2015 news item on ScienceDaily describes the research,

Researchers have been able to watch the interior cells of a plant synthesize cellulose for the first time by tricking the cells into growing on the plant’s surface.

“The bulk of the world’s cellulose is produced within the thickened secondary cell walls of tissues hidden inside the plant body,” says University of British Columbia Botany PhD candidate Yoichiro Watanabe, lead author of the paper published this week in Science.

“So we’ve never been able to image the cells in high resolution as they produce this all-important biological material inside living plants.”

An Oct. 8, 2015 University of British Columbia (UBC) news release on EurekAlert, which originated the news item, explains the interest in cellulose,

Cellulose, the structural component of cell walls that enables plants to stay upright, is the most abundant biopolymer on earth. It’s a critical resource for pulp and paper, textiles, building materials, and renewable biofuels.

“In order to be structurally sound, plants have to lay down their secondary cell walls very quickly once the plant has stopped growing, like a layer of concrete with rebar,” says UBC botanist Lacey Samuels, one of the senior authors on the paper.

“Based on our study, it appears plant cells need both a high density of the enzymes that create cellulose, and their rapid movement across the cell surface, to make this happen so quickly.”

This work, the culmination of years of research by four UBC graduate students supervised by UBC Forestry researcher Shawn Mansfield and Samuels, was facilitated by a collaboration with the Nara Institute of Technology in Japan to create the special plant lines, and researchers at the Carnegie Institution for Science at Stanford University to conduct the live cell imaging.

“This is a major step forward in our understanding of how plants synthesize their walls, specifically cellulose,” says Mansfield. “It could have significant implications for the way plants are bred or selected for improved or altered cellulose ultrastructural traits – which could impact industries ranging from cellulose nanocrystals to toiletries to structural building products.”

The researchers used a modified line of Arabidopsis thaliana, a small flowering plant related to cabbage and mustard, to conduct the experiment. The resulting plants look exactly like their non-modified parents, until they are triggered to make secondary cell walls on their exterior.

One of the other partners in this research, Stanford University’s Carnegie Institution of Science published an Oct. 8, 2015 news release on EurekAlert focusing on other aspects of the research (Note: Some of this is repetitive),

Now scientists, including Carnegie’s David Ehrhardt and Heather Cartwright, have exploited a new way to watch the trafficking of the proteins that make cellulose in the formation cell walls in real time. They found that organization of this trafficking by structural proteins called microtubules, combined with the high density and rapid rate of these cellulose producing enzymes explains how thick and high strength secondary walls are built. This basic knowledge helps us understand plants can stand upright, which was essential for the move of plants from the sea to the land, and may useful for engineering plants with improved mechanical properties for to increase yields or to produce novel bio-materials. The research is published in Science.

The live-cell imaging was conducted at Carnegie with colleagues from the University of British Columbia (UBC) using customized high-end instrumentation. For the first time, it directly tracked cellulose production to observe how xylem cells, cells that transport water and some nutrients, make cellulose for their secondary cell walls. Strong walls are based on a high density of enzymes that catalyze the synthesis of cellulose (called cellulose synthase enzymes) and their rapid movement across the xylem cell surface.

Watching xylem cells lay down cellulose in real time has not been possible before, because the vascular tissues of plants are hidden inside the plant body. Lead author Yoichiro Watanabe of UBC applied a system developed by colleagues at the Nara Institute of Science and Technology to trick plants into making xylem cells on their surface. The researchers fluorescently tagged a cellulose synthase enzyme of the experimental plant Arabidopsis to track the activity using high-end microscopes.

“For me, one of the most exciting aspects of this study was being able to observe how the microtubule cytoskeleton was actively directing the synthesis of the new cell walls at the level of individual enzymes. We can guess how a complex cellular process works from static snapshots, which is what we usually have had to work from in biology, but you can’t really understand the process until you can see it in action. ” remarked Carnegie’s David Ehrhardt.

Interfaces are the device—organic semiconductors and their edges

Researchers at the University of British Columbia (UBC; Canada) have announced a startling revelation according to an Oct. 6, 2015 news item on ScienceDaily,

As the push for thinner and faster electronics continues, a new finding by University of British Columbia scientists could help inform the design of the next generation of cheaper, more efficient devices.

The work, published this week in Nature Communications, details how electronic properties at the edges of organic molecular systems differ from the rest of the material.

An Oct. 6, 2015 UBC news release on EurekAlert, which originated the news item, expands on the theme,

Organic [as in carbon-based] materials–plastics–are of great interest for use in solar panels, light emitting diodes and transistors. They’re low-cost, light, and take less energy to produce than silicon. Interfaces–where one type of material meets another–play a key role in the functionality of all these devices.

“We found that the polarization-induced energy level shifts from the edge of these materials to the interior are significant, and can’t be neglected when designing components,” says UBC PhD researcher Katherine Cochrane, lead author of the paper.

‘While we were expecting some differences, we were surprised by the size of the effect and that it occurred on the scale of a single molecule,” adds UBC researcher Sarah Burke, an expert on nanoscale electronic and optoelectronic materials and author on the paper.

The researchers looked at ‘nano-islands’ of clustered organic molecules. The molecules were deposited on a silver crystal coated with an ultra-thin layer of salt only two atoms deep. The salt is an insulator and prevents electrons in the organic molecules from interacting with those in the silver–the researchers wanted to isolate the interactions of the molecules.

Not only did the molecules at the edge of the nano-islands have very different properties than in the middle, the variation in properties depended on the position and orientation of other molecules nearby.

The researchers, part of UBC’s Quantum Matter Institute, used a simple, analytical model to explain the differences which can be extended to predict interface properties in much more complex systems, like those encountered in a real device.

Herbert Kroemer said in his Nobel Lecture that ‘The interface is the device’ and it’s equally true for organic materials,” says Burke. [emphasis mine] “The differences we’ve seen at the edges of molecular clusters highlights one effect that we’ll need to consider as we design new materials for these devices, but likely they are many more surprises waiting to be discovered.”

Cochrane and colleagues plan to keep looking at what happens at interfaces in these materials and to work with materials chemists to guide the design rules for the structure and electronic properties of future devices.

Methods

The experiment was performed at UBC’s state-of-the-art Laboratory for Atomic Imaging Research, which features three specially designed ultra-quiet rooms that allow the instruments to sit in complete silence, totally still, to perform their delicate measurements. This allowed the researchers to take dense data sets with a tool called a scanning tunnelling microscope (STM) that showed them the energy levels in real-space on the scale of single atoms.

Pronounced polarization-induced energy level shifts at boundaries of organic semiconductor nanostructures by K. A. Cochrane, A. Schiffrin, T. S. Roussy, M. Capsoni, & S. A. Burke. Nature Communications 6, Article number: 8312 doi:10.1038/ncomms9312 Published 06 October 2015

This paper is open access. Yes, I borrowed from Nobel Laureate, Herbert Kroemer for the headline. As Woody Guthrie (legendary American folksinger) once said, more or less, “Only steal from the best.”

Of Canadian 2015 election science debates and science weeks

You’d think science and technology might rate a mention in a debate focused on the economy but according to all accounts, that wasn’t the case last night in a Sept. 17, 2015 Canadian federal election debate featuring three party leaders, Justin Trudeau of the Liberal Party, Thomas Mulcair of the New Democratic Party (NDP), and Stephen Harper, Prime Minister and leader of the Conservative Party. BTW, Elizabeth May, leader of the Green Party, was not invited but managed to participate by tweeting video responses to the debate questions. For one of the more amusing and, in its way, insightful commentaries on the debate, there’s a Sept. 17, 2015 blog posting on CBC [Canadian Broadcasting Corporation] News titled: ‘Old stock Canadians,’ egg timer, creepy set top debate’s odd moments; Moderator David Walmsley’s Irish accent and a ringing bell get reaction on social media.

As for science and the 2015 Canadian federal election, Science Borealis has compiled an informal resource list in a Sept. 18, 2015 posting and while I’ve excerpted the resources where you can find suggested questions for candidates, there’s much more to be found there,

 

 

Interestingly, the journal Nature has published a Sept. 17, 2015 article (h/t @CBC Quirks) by Nicola Jones featuring the Canadian election and science concerns and the impact science concerns have had on opposition party platforms (Note: Links have been removed),

Canadians will head to the polls on 19 October [2015], in a federal election that many scientists hope will mark a turning point after years of declining research budgets and allegations of government censorship.

In an unprecedented move, the Professional Institute of the Public Service of Canada — a union in Ottawa that represents more than 57,000 government scientists and other professionals — is campaigning in a federal race. “Here’s how we do things in the Harper government,” declares one of the union’s radio advertisements. “We muzzle scientists, we cut research and we ignore anyone who doesn’t tell us what we want to hear.”

Science advocates see little chance that their issues will be aired during a 17 September [2015] debate in Calgary that will pit Harper against NDP [New Democratic Party] leader Thomas Mulcair and Liberal leader Justin Trudeau. But concerns about the state of Canadian science have nevertheless influenced party platforms.

The middle-left Liberal Party has made scientific integrity part of its election campaign, proposing the creation of a central public portal to disseminate government-funded research. The party seeks to appoint a chief science officer to ensure the free flow of information.

Similarly, the NDP has called for a parliamentary science officer, a position that would be independent of the majority party or coalition leading the government.

Adding to the concern about the practice of science in Canada is the delayed release of a biennial report from the government’s Science, Technology and Innovation Council (STIC). Paul Wells in a June 26, 2015 article for Maclean’s Magazine discusses the situation (Note: Links have been removed),

It is distressing when organizations with no partisan role play the sort of games partisans want. The latest example is the advisory board that the Harper government created to tell it how Canada is doing in science.

I have written about the Science, Technology and Innovation Council every two years since it produced its first major report, in May 2009. STIC, as it’s known, is not some fringe group of pinko malcontents trying to stir up trouble and turn the people against their right and proper governing party. It was conceived by the Harper government (in 2007), appointed by the Harper government (in bits ever since), and it consists, in part, of senior officials who work with the Harper government every day. …

This group gives the feds the best advice they can get about how Canada is faring against other countries in its science, research and technology efforts. Its reports have been increasingly discouraging.

Perhaps you wonder: What’s the situation now? Keep wondering. Every previous STIC biennial report was released in the spring. This winter, I met a STIC member, who told me the next report would come out in May 2015 and that it would continue most of the declining trend lines established by the first three reports. I wrote to the STIC to ascertain the status of the latest report. Here’s the answer I received:

“Thank you for your interest. STIC’s next State of the Nation report will be released later in the Fall. We will be happy to inform you of the precise date and release details when they have been confirmed.”

There is no reason this year’s report was not released in the spring, as every previous report was. None except the approach of a federal election.

Getting back to a national science debate, I have written about a proposed debate to be held on the CBC Quirks and Quarks radio programme here in a Sept. 3, 2015 posting which also features a local upcoming (on Weds., Sept. 23, 2015) election science and technology debate amongst  federal candidates in Victoria, BC. I cannot find anything more current about the proposed national science debate other than the CBC radio producer’s claim that it would occur in early October. Earlier today (Sept. 18, 2015) I checked their Twitter feed (https://twitter.com/CBCQuirks) and their website (http://www.cbc.ca/radio/quirks). I wonder what’s taking so long for an announcement. In the space of a few hours, I managed to get Ted Hsu and Lynne Quarmby, science shadow ministers for the Liberal and Green parties, respectively, to express interest in participating.

Well, whether or not there is a 2015 national science debate, I find the level of interest, in contrast to the 2011 election, exciting and affirming.

In the midst of all this election and science discussion, there are some big Canadian science events on the horizon. First and technically speaking not on the horizon, there’s Beakerhead (a smashup of art, science, and engineering) in Calgary, Alberta which runs from Sept. 16 – 20, 2015. Here are a few of the exhibits and installations you can find should you get to Calgary in time (from a Sept. 16, 2015 Beakerhead news release),

The five days of Beakerhead officially get rolling today with the world’s largest pop-up gallery, called a String (Theory) of Incredible Encounters, with a circumference of five kilometres around downtown Calgary.

The series of public art installations is an exploration in creativity at the crossroads of art, science and engineering, and can be seen by touring Calgary’s neighbourhoods, from Inglewood to East Village to Victoria Park, 17th Ave and Kensington. The home base or hub for Beakerhead this year is at Station B (the Beakerhead moniker for installations at Fort Calgary).

Station B is home to two other massive firsts – a 30-foot high version of the arcade claw game, and a 6,400 square foot sandbox – all designed to inspire human ingenuity.

Beakerhead 2015 event will erupt on the streets and venues of Calgary from September 16 to 20, and includes more than 160 collaborators and 60 public events, ranging from theatre where the audience is dining as part of the show to installations where you walk through a human nose. More than 25,000 students will be engaged in Beakerhead through field trips, classroom visits and ingenuity challenges.

Just as Beakerhead ends, Canada’s 2015 Science Literacy Week opens Sept. 21 – 27, 2015. Here’s more about the week from a Sept. 18, 2015 article by Natalie Samson for University Affairs,

On Nov. 12 last year [2014], the European Space Agency landed a robot on a comet. It was a remarkable moment in the history of space exploration and scientific inquiry. The feat amounted to “trying to throw a dart and hit a fly 10 miles away,” said Jesse Hildebrand, a science educator and communicator. “The math and the physics behind that is mindboggling.”

Imagine Mr. Hildebrand’s disappointment then, as national news programs that night spent about half as much time reporting on the comet landing as they did covering Barack Obama’s gum-chewing faux pas in China. For Mr. Hildebrand, the incident perfectly illustrates why he founded Science Literacy Week, a Canada-wide public education campaign celebrating all things scientific.

From Sept. 21 to 27 [2015], several universities, libraries and museums will highlight the value of science in our contemporary world by hosting events and exhibits on topics ranging from the lifecycle of a honeybee to the science behind Hollywood films like Jurassic World and Contact.

Mr. Hildebrand began developing the campaign last year, shortly after graduating from the University of Toronto with a bachelor’s degree in ecology and evolutionary biology. He approached the U of T Libraries for support and “it really snowballed from there,” the 23-year-old said.

Though Mr. Hildebrand said Science Literacy Week wasn’t inspired by public criticism against the federal government’s approach to scientific research and communication, he admitted that it makes the campaign seem that much more important. “I’ve always wanted to shout from the rooftops how cool science is. This is my way of shouting from the rooftops,” he said.

In the lead-up to Science Literacy Week, museum scientists with the Alliance of Natural History Museums of Canada have been posting videos of what they do and why it’s important under the hashtag #canadalovesscience. The end of the campaign will coincide with a lunar eclipse and will see several universities and observatories hosting stargazing parties.

You can find out more about this year’s events on the Science Literacy Week website. Here are a few of the BC events I found particularly intriguing,

While it’s still a month away, there is Canada’s upcoming 2015 National Science and Technology Week, which will run from Oct. 16 – 25. To date, they do not have any events listed for this year’s week but they do invite you to submit your planned event for inclusion in their 2015 event map and list of events.

Extreme graphene—University of British Columbia (Canada) researchers* create first superconducting graphene

There haven’t been too many announcements about Canadian research into graphene so it was nice to receive a news release about a first in the field achieved by researchers at the University of British Columbia (UBC; Canada). From a Sept. 4, 2015 UBC news announcement (also on EurekAlert)*,

Graphene, the ultra-thin, ultra-strong material made from a single layer of carbon atoms, just got a little more extreme. UBC physicists have been able to create the first ever superconducting graphene sample by coating it with lithium atoms.

Although superconductivity has already been observed in intercalated bulk graphite—three-dimensional crystals layered with alkali metal atoms, based on the graphite used in pencils—inducing superconductivity in single-layer graphene has until now eluded scientists.

“This first experimental realization of superconductivity in graphene promises to usher us in a new era of graphene electronics and nanoscale quantum devices,” says Andrea Damascelli, director of UBC’s Quantum Matter Institute and leading scientist of the Proceedings of the National Academy of Sciences [PNAS] study outlining the discovery.

Graphene, roughly 200 times stronger than steel by weight, is a single layer of carbon atoms arranged in a honeycomb pattern. Along with studying its extreme physical properties, scientists eventually hope to make very fast transistors, semiconductors, sensors and transparent electrodes using graphene.

“This is an amazing material,’” says Bart Ludbrook, first author on the PNAS paper and a former PhD researcher in Damascelli’s group at UBC. “Decorating monolayer graphene with a layer of lithium atoms enhances the graphene’s electron–phonon coupling to the point where superconductivity can be stabilized.”

Given the massive scientific and technological interest, the ability to induce superconductivity in single-layer graphene promises to have significant cross-disciplinary impacts. According to financial reports, the global market for graphene reached $9 million in 2014 with most sales in the semiconductor, electronics, battery, energy, and composites industries.

The researchers, which include colleagues at the Max Planck Institute for Solid State Research through the joint Max-Planck-UBC Centre for Quantum Materials, prepared the lithium-decorated graphene in ultra-high vacuum conditions and at ultra-low temperatures (-267 degrees Celsius or 5 Kelvin), to achieve this breakthrough.

UBC’s Quantum Matter Institute

UBC’s Quantum Matter Institute (QMI) is internationally recognized for its research and discoveries in quantum structures, quantum materials, and applications towards quantum devices. A recent $66.5-million investment from the Canada First Research Excellence Fund will broaden the scope of QMI’s research and support the discovery of practical applications for computing, electronics, medicine and sustainable energy technologies.

Last May (2015), Dr. Damascelli recorded an interview as part of the Research2Reality, a Canadian science media engagement project, where he discusses his work with graphene superconductors and notes the team had just managed a successful test of the new material,

TRIUMF accelerator used by US researchers to visualize properties of nanoscale materials

The US researchers are at the University of California at Los Angeles (UCLA) and while it’s not explicitly stated I’m assuming the accelerator they mention at TRIUMF (Canada’s national laboratory for particle and nuclear physics) has something special as there are accelerators in California and other parts of the US.

A July 15, 2015 news item on Nanotechnology Now announces the latest on visualizing the properties of nanoscale materials,

Scientists trying to improve the semiconductors that power our electronic devices have focused on a technology called spintronics as one especially promising area of research. Unlike conventional devices that use electrons’ charge to create power, spintronic devices use electrons’ spin. The technology is already used in computer hard drives and many other applications — and scientists believe it could eventually be used for quantum computers, a new generation of machines that use quantum mechanics to solve complex problems with extraordinary speed.

A July 15, 2015 UCLA news release, which originated the news item, expands on the theme and briefly mentions TRIUMF’s accelerator (Note: A link has been removed),

Emerging research has shown that one key to greatly improving performance in spintronics could be a class of materials called topological insulators. Unlike ordinary materials that are either insulators or conductors, topological insulators function as both simultaneously — on the inside, they are insulators but on their exteriors, they conduct electricity.

But topological insulators have certain defects that have so far limited their use in practical applications, and because they are so tiny, scientists have so far been unable to fully understand how the defects impact their functionality.

The UCLA researchers have overcome that challenge with a new method to visualize topological insulators at the nanoscale. An article highlighting the research, which was which led by Louis Bouchard, assistant professor of chemistry and biochemistry, and Dimitrios Koumoulis, a UCLA postdoctoral scholar, was published online in the Proceedings of the National Academy of Sciences.

The new method is the first use of beta‑detected nuclear magnetic resonance to study the effects of these defects on the properties of topological insulators.

The technique involves aiming a highly focused stream of ions at the topological insulator. To generate that beam of ions, the researchers used a large particle accelerator called a cyclotron, which accelerates protons through a spiral path inside the machine and forces them to collide with a target made of the chemical element tantalum. This collision produces lithium-8 atoms, which are ionized and slowed down to a desired energy level before they are implanted in the topological insulators.

In beta‑detected nuclear magnetic resonance, ions (in this case, the ionized lithium-8 atoms) of various energies are implanted in the material of interest (the topological insulator) to generate signals from the material’s layers of interest.

Bouchard said the method is particularly well suited for probing regions near the surfaces and interfaces of different materials.

In the UCLA research, the high sensitivity of the beta‑detected nuclear magnetic resonance technique and its ability to probe materials allowed the scientists to “see” the impacts of the defects in the topological insulators by viewing the electronic and magnetic properties beneath the surface of the material.

The researchers used the large TRIUMF cyclotron in Vancouver, British Columbia.

According to the UCLA news release, there were also researchers from the University of British Columbia, the University of Texas at Austin and Northwestern University *were* involved with the work.
