A new study puts a fresh spin on what it means to “go with your gut.” The findings, published in Nature, suggest that gut bacteria may control movement in fruit flies and identify the neurons involved in this response. The study was supported by the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health.

In 40 years, human actions like deforestation have taken a major toll on wildlife, a new report finds.

Two men who were paralysed in separate accidents more than six years ago can stand and walk short distances on crutches after their spinal cords were treated with electrical stimulation.

David Mzee, 28, and Gert-Jan Oskam, 35, had electrical pulses beamed into their spines to stimulate their leg muscles as they practised walking in a supportive harness on a treadmill.

Based on observations by the European Souther Observatory’s GRAVITY instrument, this simulation shows gases swirling around the black hole at the center of the Milky Way — at just 30% the speed of light — “the first time material has been observed orbiting close to the point of no return.”

Perhaps the most important supernova of the modern era is SN 1987A, the closest supernova to Earth since the invention of the telescope. Scientists have been observing the explosion’s remnants since the 1987 event.

Scientists led by University of Toronto graduate student Yvette Cendes have presented a new report showing the 25 years of radio wave observations of the stellar corpse’s evolution from 1992 to 2017. You can watch those observations in the timelapse below.

At Quora.com, I respond to quetions on Bitcoin and Cryptocurrency. Today, a reader asked “Will we all be using a blockchain-based currency some day?”.

This is an easy question to answer, but not for usual Geeky reasons: A capped supply, redundant bookkeeping, privacy & liberty or blind passion. No, these are all tangential reasons. But first, let’s be clear about the answer:

Yes, Virginia. We are all destined to move,
eventually, to a blockchain based currency.

I am confident of this because of one enormous benefit that trumps all other considerations. Also, because of flawed arguments behind perceived negatives.

Yesterday, we announced the successful completion of the NAD+ Mouse Project after a great fundraiser, but it seems we are not done yet. The research team at Harvard has announced a new stretch goal for the last two days of the campaign.

A new $75,000 goal is to be the final step, and to support that, Dr. David Sinclair is offering to fund match the next $5000 in donations to the project to help it reach this final goal. So, for the next two days, all donations are worth double.

The final goal will be to add even more comprehensive testing, such as end-of-life pathology (frequency and specificity of neoplasms/tumors/cancer) and MRI diagnostics (body composition, lean-to-fat ratio). This would really allow the researchers to maximize the useful data they collect during the study and help assess any changes to cancer risk, why each animal died, and what age-related diseases were affected by the drug.

The find offers a glimpse into a previously unknown marine ecosystem — and spotlights just how little we know about the seafloor.

Scientists uncovered a chain of volcanic seamounts off the coast of the Australian island of Tasmania.
