New Mars discoveries are advancing the case for possible life on the red planet, past or even present.
Scientists reported Thursday that NASA’s Curiosity rover has found potential building blocks of life in an ancient Martian lakebed. Hints have been found before, but this is the best evidence yet.
In the 1966 science fiction classic "Fantastic Voyage," a submarine crew is miniaturized so it can squeeze inside a human body and travel to a hot spot where medical assistance is needed.
A team from MIT has adapted this idea for real life, replacing the shrunken squad with specially engineered E. coli bacteria and pairing them with a suite of electronics that fit neatly inside an ingestible pill.
What would it take to make a copy of your brain?
With the days of blurry mimeographs behind us and the technology to make copies spreading into 3D- and cyberspace, the possibilities might seem almost limitless. But are they?
Physics itself—not technology, not human ingenuity—forbids perfect cloning, which might throw a kink in your plan to upload your brain.
An asteroid lurking near the orbit of Jupiter is the first known immigrant from beyond our solar system to take up permanent residence in our corner of the cosmos. Scientists say the interstellar expat could help us understand how life started on Earth and perhaps in other places too.
Astronomers say the space rock known as 2015 BZ509 is the first to come for a visit and wind up staying.
Stephen Hawking, the British physicist and author of A Brief History of Time, has passed away at the age of 76.
"He was a great scientist and an extraordinary man whose work and legacy will live on for many years," according to a statement released to British media early Wednesday morning.
The brain can take over functions of injured parts of the brain. It can create new neural pathways and even make new brain cells, contrary to what scientists used to think.
"The brain is like the body – the more we exercise, the better it works," said Espen Dietrichs, a neurology professor, brain researcher and writer, in a lecture on how flexible the brain is. He spoke recently at an evening event in Oslo organized by the Norway’s national association for heart and lung disorders (LHL) and LHL Hjerneslag, as part of the fourth national conference on the heart and brain.
How did life start? There may not be a bigger question. To learn the secret of our origins means going back beyond the earliest forms of biological life, past simple bacteria, and down to the chemistry of the building blocks that came earlier.
The future of technology is about more than just increasing raw processing power and embracing the likes of quantum computing -- storage is also a serious concern. We already generate huge amounts of data, and the amount we need to store is only going to increase.
American scientists released two new major studies investigating whether or not there’s connection between cancer risk and cell phone use and the much-awaited answer is…*drumroll, please*…we still don’t really know anything for certain.
Aaron Traywick dropped his pants and prepared to plunge a small syringe into his left thigh. His colleagues leaned in to get a closer look. The audience in the crowd was momentarily silent, as if gritting their teeth and holding their breath.
The syringe was filled with an experimental herpes therapy based on a treatment method only previously tested in mice, and Traywick was about to become the first human to ever try it. On stage. In front of an audience. With his pants down.
