In my last post, I talked about the idea of warp drive and whether it might one day be possible. Today I’ll talk about another faster-than-light trick: wormholes.

Wormholes are an old idea in general relativity. It’s based on work by Albert Einstein and Nathan Rosen, who tried to figure out how elementary particles might behave in curved spacetime. Their idea treated particle-antiparticle pairs as two ends of a spacetime tube.

This Einstein-Rosen Bridge would look like a black hole on one end, and an anti-black hole, or white hole, on the other end.

Researchers at Los Alamos discover neural network reaps benefits ‘equivalent to a good night’s rest’.

Nvidia researchers created an AI system that can synthesize video games simply by watching videos of other games, as well as actions taken in those games.

Scientists have taken a step forward in their ability to decode what a person is saying just by looking at their brainwaves when they speak.

They trained algorithms to transfer the brain patterns into sentences in real-time and with word error rates as low as 3%.

Previously, these so-called “brain-machine interfaces” have had limited success in decoding neural activity.

My day was completely ruined yesterday when I stumbled upon a fun fact that absolutely obliterated my mind. I saw this tweet yesterday that said that not everyone has an internal monologue in their head. All my life, I could hear my voice in my head and speak in full sentences as if I was talking out loud. I thought everyone experienced this, so I did not believe that it could be true at that time.

Literally the first person I asked was a classmate of mine who said that she can not “hear” her voice in her mind. I asked her if she could have a conversation with herself in her head and she looked at me funny like I was the weird one in this situation. So I began to become more intrigued. Most peo ple I asked said that they have this internal monologue that is running ram pant throughout the day. However, every once in a while, someone would say that they don’t experience this.

These scientists keep proving that reducing prejudice is possible. It’s just not easy.

The coldest chemical reaction in the known universe took place in what appears to be a chaotic mess of lasers. The appearance deceives: Deep within that painstakingly organized chaos, in temperatures millions of times colder than interstellar space, Kang-Kuen Ni achieved a feat of precision. Forcing two ultracold molecules to meet and react, she broke and formed the coldest bonds in the history of molecular couplings.

“Probably in the next couple of years, we are the only lab that can do this,” said Ming-Guang Hu, a postdoctoral scholar in the Ni lab and first author on their paper published today in Science. Five years ago, Ni, the Morris Kahn Associate Professor of Chemistry and Chemical Biology and a pioneer of ultracold chemistry, set out to build a new apparatus that could achieve the lowest temperature chemical reactions of any currently available technology. But they couldn’t be sure their intricate engineering would work.

Now, they not only performed the coldest reaction yet, they discovered their new apparatus can do something even they did not predict. In such intense cold—500 nanokelvin or just a few millionths of a degree above absolute zero—their molecules slowed to such glacial speeds, Ni and her team could see something no one has been able to see before: the moment when two molecules meet to form two new molecules. In essence, they captured a chemical reaction in its most critical and elusive act.

WHAT IS A COGNITIVE BIAS? Humans tend to think in certain ways that can lead to systematic deviations from making rational judgments. These tendencies usually arise from:
