Don’t be fooled by the fog machine, spooky lights and fake bats: the robotics lab at Worcester Polytechnic Institute lab isn’t hosting a Halloween party.

Instead, it’s a testing ground for tiny drones that can be deployed in search and rescue missions even in dark, smoky or stormy conditions.

“We all know that when there’s an earthquake or a tsunami, the first thing that goes down is power lines. A lot of times, it’s at night, and you’re not going to wait until the next morning to go and rescue survivors,” said Nitin Sanket, assistant professor of robotics engineering...

As more and more exoplanets are discovered throughout the galaxy, scientists find some that defy explanation—at least for awhile. A new study, published in Nature, describes a process that might explain why a large portion of exoplanets have water on their surface, even when it doesn’t make sense.

Water where it shouldn’t be
A particular category of exoplanets that are between the size of Earth and Neptune, referred to as “sub-Neptunes,” generally have a rocky core, which is surrounded by an envelope of either hydrogen or water...

Even small amounts of bisphenol A can lead to long-term health effects. When researchers studied adult rats exposed in the fetal stage, they found that females had developed a more masculine and males a more feminine gene expression pattern. This led to females progressing towards a cancer-like state, while males progressed towards metabolic syndrome, which can increase the risk of diabetes and heart disease.

Bisphenol A is a synthetic chemical with estrogen-like properties that is commonly used in food packaging materials. The substance is banned in many products, but is still present in some packaging. Levels of bisphenol A in people’s bodies are often above levels considered safe, with previous research showing that the substance can cause adverse health effects.

Researchers at the USC Viterbi School of Engineering and School of Advanced Computing have developed artificial neurons that replicate the complex electrochemical behavior of biological brain cells.

The innovation, documented in Nature Electronics, is a leap forward in neuromorphic computing technology...
