Move over, pot: Psychedelic companies are about to go public

February 20, 2020

The first companies developing medical treatments from psychedelic drugs like LSD, ketamine and the active ingredient in magic mushrooms are gearing up to list on Canadian stock exchanges.

Mind Medicine Inc., which is undertaking clinical trials of psychedelic-based drugs, intends to list on Toronto’s NEO Exchange by the first week of March, said JR Rahn, the company’s co-founder and co-chief executive officer. A NEO spokesman confirmed the listing, which is pending final approvals.

The company plans to list via a reverse takeover under the ticker MMED. It’s not yet generating revenue and is targeting a valuation of approximately $50 million, Rahn said. MindMed counts former Canopy Growth Corp. co-CEO Bruce Linton as a director and Shark Tank star Kevin O’Leary as an investor.

“Our ambition is to be one of the first publicly listed neuro-pharmaceutical companies developing psychedelic medicines,” Rahn said in a phone interview.

What’s in your water? Researchers identify new toxic byproducts of disinfecting drinking water

February 20, 2020

When phenols, compounds that are commonly found in drinking water, mix with chlorine, hundreds of unknown, potentially toxic byproducts are formed.

Mixing drinking water with chlorine, the United States’ most common method of disinfecting drinking water, creates previously unidentified toxic byproducts, says Carsten Prasse from Johns Hopkins University and his collaborators from the University of California, Berkeley and Switzerland.

The researchers’ findings were published this past week in the journal Environmental Science & Technology.

“There’s no doubt that chlorine is beneficial; chlorination has saved millions of lives worldwide from diseases such as typhoid and cholera since its arrival in the early 20th century,” says Prasse, an assistant professor of Environmental Health and Engineering at The Johns Hopkins University and the paper’s lead author.

“But that process of killing potentially fatal bacteria and viruses comes with unintended consequences. The discovery of these previously unknown, highly toxic byproducts, raises the question how much chlorination is really necessary.”

Engineers just built an impressively stable quantum silicon chip from artificial atoms

February 19, 2020

Newly created artificial atoms on a silicon chip could become the new basis for quantum computing.

Engineers in Australia have found a way to make these artificial atoms more stable, which in turn could produce more consistent quantum bits, or qubits – the basic units of information in a quantum system.

The research builds on previous work by the team, wherein they produced the very first qubits on a silicon chip, which could process information with over 99 percent accuracy. Now, they have found a way to minimise the error rate caused by imperfections in the silicon.

“What really excites us about our latest research is that artificial atoms with a higher number of electrons turn out to be much more robust qubits than previously thought possible, meaning they can be reliably used for calculations in quantum computers,” said quantum engineer Andrew Dzurak of the University of New South Wales (UNSW) in Australia.

“This is significant because qubits based on just one electron can be very unreliable.”

Replacement blood vessels may be woven from bio-yarn

February 19, 2020

Blood vessels made from the yarn should reportedly be tolerated by all patients

When a damaged blood vessel has to be replaced, it’s important that the replacement be well-tolerated by the body. And while bioprinted blood vessels are one possibility, French scientists are now working on weaving the things out of collagen yarn.

Led by researcher Nicolas L’Heureux, a team at the Inserm institute – aka the French National Institute of Health and Medical Research – started by lab-cultivating human cells, which in turn produced extracellular matrix deposits that were high in collagen. The extracellular matrix is the three-dimensional network of macromolecules that surrounds the body’s cells, helping to keep those cells structurally and biochemically supported.

Sheets of the lab-grown matrix deposits were next cut into very thin fiber-like strips, forming the yarn. It can be woven, knitted or braided, and has already been used to create vascular grafts (implantable tubes for redirecting the flow of blood). Those grafts exhibited “burst pressure, suture retention strength and transmural permeability that surpassed clinical requirements.”

Chinese government rolls out coronavirus ‘close contact detector’ app

February 18, 2020

China has rolled out an app that lets people check whether they have been in close contact with someone infected by the coronavirus.

The “close contact detector,” as BBC puts it, notifies users if they have had exchanges with any individuals who have been confirmed or suspected of carrying the virus. All users need to do is scan a QR code with an app like Alipay or WeChat. People at risk are then advised to stay at home or inform local health authorities.

Once their phone number is linked, users are asked to fill in their name and ID number. The app can then be used to check the status of up to three ID numbers. The app, which was developed in cooperation by the government and the China Electronics Technology Group Corporation, relies on data from from the health and transport authorities.

Although the invasiveness of the software certainly raises questions about the obtrusive surveillance practices within the country, experts believe citizens won’t see the new app as controversial, considering the extent of the epidemic.

Graphene amplifier unlocks hidden frequencies in the electromagnetic spectrum

Researchers have created a unique device which will unlock the elusive terahertz wavelengths and make revolutionary new technologies possible.

Terahertz waves (THz) sit between microwaves and infrared in the light frequency spectrum, but due to their low energy, scientists have been unable to harness their potential. The conundrum is known in scientific circles as the “terahertz gap.”

Being able to detect and amplify THz waves (T-rays) would open up a new era of medical, communications, satellite, cosmological and other technologies. One major application would be as a safe, non-destructive alternative to X-rays. However, until now, the wavelengths, which range between 3mm and 30μm, have proved impossible to use due to relatively weak signals from all existing sources.

A team of physicists has created a new type of optical transistor—a working THz amplifier—using graphene and a high-temperature superconductor. The physics behind the simple amplifier relies on the properties of graphene, which is transparent and is not sensitive to light and whose electrons have no mass. It is made up of two layers of graphene and a superconductor that trap the graphene massless electrons between them like a sandwich.

The University of Rochester research lab that recently used lasers to create unsinkable metallic structures has now demonstrated how the same technology could be used to create highly efficient solar power generators.

In a paper in Light: Science & Applications, the lab of Chunlei Guo, professor of optics also affiliated with Physics and the Material Sciences Program, describes using powerful femto-second laser pulses to etch metal surfaces with nanoscale structures that selectively absorb light only at the solar wavelengths, but not elsewhere.

This Colorado college will start offering a cannabis major in the fall

February 18, 2020

(CNN) Students on Colorado State University’s Pueblo campus will have the option to study cannabis beginning this fall.

State officials on Friday approved a bachelor’s of science degree program in Cannabis Biology and Chemistry, according to the Colorado Department of Higher Education, which said it was one of the first such programs in the country.

“The new major is a pro-active response to a rapidly changing national scene regarding the cannabis plant,” a proposal for the program by CSU-Pueblo officials says, citing shifting attitudes toward cannabis and its legalization for recreational use in numerous states, including Colorado.

The program will be part of CSU-Pueblo’s department of chemistry and consist mainly of chemistry and biology coursework with some classes in math and physics, the proposal says.

The secret to winning the war for talent

February 17, 2020

In the long siege known as the war for talent, employers need a new battle plan. Instead of trying desperately to recruit from the outside to fill a growing skills gap, companies should turn to the resources that exist within their own workforces.

This is a build versus buy strategy, with greater emphasis placed on training to develop skills in-house to meet the organization’s current and future needs. As a recent Harvard Business Review article observed, rather than spending billions to acquire talent, a better approach is investing in the talent that’s already in place. “Poach-and-release is no longer a sustainable model for talent acquisition,” the authors write.

There is a greater-than-ever need for effective and efficient corporate training as the shortage of skilled workers heightens to an urgent business issue. At an education conference I attended recently, Senator Pat Toomey (R-Pa.) told the audience that the concern he hears most frequently from employers is the difficulty of hiring enough workers.

8 powerful examples of AI for good

February 17, 2020

Amid the cacophony of concern over artificial intelligence (AI) taking over jobs (and the world) and cheers for what it can do to increase productivity and profits, the potential for AI to do good can be overlooked. Technology leaders such as Microsoft, IBM, Huawei and Google have entire sections of their business focused on the topic and dedicate resources to build AI solutions for good and to support developers who do. In the fight to solve extraordinarily difficult challenges, humans can use all the help we can get. Here are 8 powerful examples of artificial intelligence for good as it is applied to some of the toughest challenges facing society today.

There are more than 1 billion people living with a disability around the world. Artificial intelligence can be used to amplify these people’s abilities to improve their accessibility. It can facilitate employment, improve daily life and help people living with disabilities communicate. From opening up the world of books to deaf children to narrating what it “sees” to those with visual impairments, apps and tools powered by artificial intelligence are improving accessibility.

New theory of complex emotions

February 17, 2020

If You Can Say It, You Can Feel It Some scientists believe we have infinite emotions, so long as we can name them.

Sometime last year, I came across the word hangxiety, a neologism for hangover-induced anxiety. I cringed when I read it; it felt so phony.

The most mental distress I’d ever experienced during a hangover was some light teasing in a group chat. And then, last fall, the morning after a night of drinking, I woke up with a racing heart and a constricted feeling across my chest, as if I’d been sleeping under a dozen weighted blankets. I thought about the things I’d said and done the night before, and the physical sensations intensified.

This happened again, and then again. I haven’t had a hangover in months, largely because I’m terrified of them now. Was this always the way my brain and body responded to hangovers? Or did learning about hangxiety somehow influence the way I experience a hangover? I’d like to think I’m not that suggestible, but some emerging, somewhat controversial research on how and why we feel our feelings argues that language doesn’t just describe a feeling. It can also change it.
