WASHINGTON — SpaceX Chief Executive Elon Musk said April 27 that he hopes to test a new way to reduce the brightness of the company’s Starlink satellites on the next launch for the broadband megaconstellation.

In a briefing to a committee working on the next astrophysics decadal survey, Musk said the experimental “VisorSat,” along with a new approach for orienting Starlink satellites as they raise their orbits, should address concerns raised by astronomers that the Starlink constellation could interfere with their observations.

“Our objectives, generally, are to make the satellites invisible to the naked eye within a week, and to minimize the impact on astronomy, especially so that we do not saturate observatory detectors and inhibit discoveries,” Musk said.

Can we study AI the same way we study lab rats? Researchers at DeepMind and Harvard University seem to think so. They built an AI-powered virtual rat that can carry out multiple complex tasks. Then, they used neuroscience techniques to understand how its artificial “brain” controls its movements.

Today’s most advanced AI is powered by artificial neural networks —machine learning algorithms made up of layers of interconnected components called “neurons” that are loosely inspired by the structure of the brain. While they operate in very different ways, a growing number of researchers believe drawing parallels between the two could both improve our understanding of neuroscience and make smarter AI.

New technique could help shed light on plants’ workings – and lead to unusual home decor.

As an AI Consultant, I often have to evaluate AI startups to determine if their solutions would make sense for us and if they can become a real business partner over the long term. Our process for evaluating startups is more or less…

Depending on who you ask and where you are, wearing a mask can be an important part of the strategy to stop the spread of SARS-CoV-2.

With the CDC recommending surgical and N95 masks should be kept for medical personnel on the front line, if you do want or need a mask, you should be purchasing or making a cloth one.

But when looking at cloth masks, which materials work best for keeping your germs in and other people’s germs out?

Former Senate Majority Leader Harry Reid (D-Nev.) praised Monday’s release of the videos, but said more action is needed.

“I’m glad the Pentagon is finally releasing this footage, but it only scratches the surface of research and materials available,” he tweeted. “The U.S. needs to take a serious, scientific look at this and any potential national security implications. The American people deserve to be informed.”

The Pentagon on Monday officially released three videos of “unidentified” flying objects that have been previously leaked to the public.

Around the world, scientists race to develop a vaccine or treatment against the coronavirus disease (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Now, a team of researchers has found that a drug already available around the world can kill the coronavirus in a lab setting in just 48 hours.
