This will make friends Vladimir and Marina happy.

Mushrooms and game meat in European regions where Chernobyl fallout was most intense still have excess radiation, but Burgundy truffles get the green light; foodies rejoice.

It’s been 30 years since the 1986 nuclear disaster in Ukraine in which a fire and explosion at the Chernobyl Nuclear Power Plant unleashed a slew of radioactive particles into the atmosphere. Swept along by winds and settled by heavy rains, radioactive particles, especially caesium-137 (137Cs), polluted large stretches of the European continent. And we all know the problem with radioactive things, they’ve got lasting power.

“Much of the continent’s topsoil layers are still radioactively contaminated,” says Ulf Büntgen, Head of the Dendroecology Group at the Swiss Federal Research Institute (WSL) and lead author of a new study measuring something dear to a foodie’s heart: the contamination level of Burgundy truffles (Tuber aestivum), like those pictured below.

What a relief.

One day, the Universe is going to die out — that’s something scientists can agree on.

But exactly how and when that will happen is a more of a gray area, and it’s not something we’ve really had to worry about, with current predictions putting any such event tens of billions of years in the future — long after our Sun burns out.

But what if our current predictions are wrong?

The substance that provides energy to all the cells in our bodies, Adenosine triphosphate (ATP), may also be able to power the next generation of supercomputers. The discovery opens doors to the creation of biological supercomputers that are about the size of a book. That is what an international team of researchers led by Prof. Nicolau, the Chair of the Department of Bioengineering at McGill, believe. They’ve published an article on the subject earlier this week in the Proceedings of the National Academy of Sciences (PNAS), in which they describe a model of a biological computer that they have created that is able to process information very quickly and accurately using parallel networks in the same way that massive electronic super computers do.

Except that the model bio supercomputer they have created is a whole lot smaller than current supercomputers, uses much less energy, and uses proteins present in all living cells to function.

Doodling on the back of an envelope

“We’ve managed to create a very complex network in a very small area,” says Dan Nicolau, Sr. with a laugh. He began working on the idea with his son, Dan Jr., more than a decade ago and was then joined by colleagues from Germany, Sweden and The Netherlands, some 7 years ago. “This started as a back of an envelope idea, after too much rum I think, with drawings of what looked like small worms exploring mazes.”

Wifi distribution across this planet is patchwork of crazy: You can tweet from Mt. Fuji but lord help you if you want to send an email in Cuba. Thursday, Israeli company SkyFi announced it will be the one to finally soak the world in wifi from space.

In a press release announcing $3 million in funding from Jerusalem Venture Partners and the Liberty Israel Venture Fund, the company said it would get around the problems preventing reliable wifi from traditional satellites by launching nano satellites whose 55-centimeter diameter antenna could be folded up to make launching cheaper, then expanding once in orbit.

“The high flexibility of our nano satellites and the ability to provide multiple services to different customers enables us to offer free internet access to the whole planet in the same manner as GPS services are free. We think this has the potential to bridge great divides and give everyone worldwide a part in the great global connected community,” Raz Itzhaki Tamir, Co-Founder and CEO of SkyFi, said in the press announcement.

Rather than risk the lives of their astronauts, Russian government scientists are now working to develop humanoid robots that can perform complex tasks on the outside of the International Space Station (ISS) while astronauts control them safely from within the station.

The Russian Foundation for Advanced Research Projects, Russia’s military research arm unveiled two prototype robot astronauts on February 13th to the media ahead of a public robotics exhibition in Moscow.

One robot, named Fyodor, has two arms and a torso, and is programmed to either mimic an astronaut’s actions, be under remote control by a human wearing a special suit, or work autonomously.

“Vulcan Inc. today announced a new exhibition of nearly 60 objects related to science fiction and the history of space exploration – Imagined Futures: Science Fiction, Art, and Artifacts from the Paul G. Allen Family Collection – that will be on view at its 3,000-square-foot flexible concept space, Pivot Art + Culture beginning April 7, 2016. The exhibition, curated by Ben Heywood, runs through July 10, 2016.”

Demonstrating a strategy that could form the basis for a new class of electronic devices with uniquely tunable properties, researchers at Kyushu University were able to widely vary the emission color and efficiency of organic light-emitting diodes based on exciplexes simply by changing the distance between key molecules in the devices by a few nanometers.

This new way to control electrical properties by slightly changing the device thickness instead of the materials could lead to new kinds of organic electronic devices with switching behavior or that reacts to external factors.

Organic such as OLEDs and organic solar cells use thin films of for the electrically active materials, making flexible and low-cost devices possible.
