I was recently at NASA’s annual SpaceApps Hackathon and the focus this year was climate change and our team brainstormed solutions to track the causes of devastating Twisters and we noted that technology had not progressed far enough to build our tracking probes but was close to being developed.
Massive technological advances need to be made if we are going to Mars and beyond.
If we want to find extra dimensions lurking within our Universe — something that string theory attempts to explain — gravitational waves could be our key to locating them, physicists suggest.
This new hypothesis seeks to answer the long-standing mystery of why gravity appears to be weaker than the other fundamental forces in our Universe, by proposing that it’s actually ‘leaking out’ into extra dimensions we’re yet to detect.
“Extra dimensions have been discussed for a long time from different points of view,” Emilian Dudas from the École Polytechnique in France, who wasn’t involved in the study, told Leah Crane at New Scientist.
Security analysts could soon become the first employees asked to show up to work inside virtual reality.
Thanks to a new virtual reality tool built by the Colorado-based startup ProtectWise, cybersecurity professionals may soon be patrolling computer networks — like real world beat cops — inside a three-dimensional video game world.
Scott Chasin, CEO and co-founder of ProtectWise, sees a future in which companies might even have war-rooms of Oculus Rift-wearing security analysts who patrol their networks in VR. “I see an opportunity in the not-too-distant future in which a large organization who has a lot of IT infrastructure might have rooms full of security analysts with augmented reality and VR headsets on,” he told me.
A win win, assuming it can be manufactured en mass and at a reasonable price.
A University of Central Florida (UCF) chemistry professor has invented a revolutionary way to remove carbon dioxide (CO2) from air by triggering artificial photosynthesis in a synthetic material — breaking down carbon dioxide while also producing fuel for energy.
UCF Assistant Professor Fernando Uribe-Romo and his students used a synthetic material called a metal–organic framework (MOF), which converts carbon dioxide into harmless organic materials — similar to how plants convert CO2 and sunlight into food.
Researchers from the University of Antwerp and KU Leuven (University of Leuven), Belgium, have developed a process that purifies air, and at the same time, generates power. The device must only be exposed to light in order to function.
“We used a small device with two rooms separated by a membrane,” explained professor Sammy Verbruggen (UAntwerp/KU Leuven). “Air is purified on one side, while on the other side, hydrogen gas is produced from a part of the degradation products. This hydrogen gas can be stored and used later as fuel, as is already being done in some hydrogen buses, for example.”
In this way, the researchers respond to two major social needs: clean air and alternative energy production. The heart of the solution lies at the membrane level, where the researchers use specific nanomaterials. “These catalysts are capable of producing hydrogen gas and breaking down air pollution,” explains professor Verbruggen. “In the past, these cells were mostly used to extract hydrogen from water. We have now discovered that this is also possible, and even more efficient, with polluted air.”

You can see how deep-rooted is the wish of some to just ignore the problem of ageing when they say that rejuvenation won’t happen in time for them, and that there’s thus no reason they should concern themselves with the whole issue. This article on rebuts this meta-objection and discusses its origins.
People’s last line of defence to keep ignoring the problem of ageing and rejuvenation is often the meta-objection ‘it won’t happen in my lifetime’. Let’s have a look at what’s wrong with this reasoning, and why some people think this way.

–In a DAO, a blockchain-based organization, you don’t have a boss or a CEO. What you have is a dynamic set of working relationships continuously and dynamically self-organized around outcomes and projects.
If you’re tired of going to unproductive meetings, commuting in to work just to put in face time, or following commands from a boss you don’t have much confidence in, you may be the right kind of employee for a new type of work environment called a DAO, or Decentralized Autonomous Organization.
We’re in the early stages of seeing these futuristic types of companies roll out already. These early players have run into some missteps, but that’s to be expected. What’s important in the concept of a DAO is the D: “decentralized.”

NASA just announced several bounties to improve its FUN3D software, which is used to simulate fluid dynamics. The system is used internally at NASA, as well as by companies like Boeing and Lockheed, to develop and optimize new vehicles and engines.
The FUN3D project was started back in the 1980s, and it has been in active development for decades, but NASA’s looking for help to optimize the code. It’s offering $15,000 and $10,000 prizes to the top two contributors of code optimizations, and is also offering another bounty for more general optimization suggestions.
