Astronauts could one day end up eating asteroids

Astronauts could one day end up eating asteroids

A fully operational asteroid food project would require an “industrial-sized super machine” in space, he says, but the researchers hope to begin testing the idea on a smaller scale in the coming year, starting off with coal and then moving to meteorites that have fallen to Earth, which they are currently working on a proposal for.

Zap, zap, zap! Our bodies are electric

Although these feelings can be triggered by events, such as the death of a loved one or the move to a new city, that isn’t typically considered an “illness” — unless the symptoms are prolonged and harm an individual’s ability to perform normal daily tasks (such as working, sleeping or interacting with others).

‘Night Magic’ invites you to celebrate the living wonders of the dark

Henion’s night excursions continue with appearances from glowworms, which are luminous fly larvae that shine blue; colorful moths, major pollinators that are experiencing troubling population declines; and foxfire, the catchall term for bioluminescent fungi glowing on forest floors.


Can you see Earth’s new ‘minimoon’ with the naked eye?

Can you see Earth’s new ‘minimoon’ with the naked eye?

Given the relatively easy trip to a minimoon from Earth, some researchers have proposed using these transient satellites as "stepping stones" for future missions to mine asteroids or explore deeper into our solar system.

World’s oldest cheese found on 3500-year-old Chinese mummies

Based on the presence of yeast, lactic acid bacteria and proteins from ruminant milk in the samples, Qiaomei Fu at the Chinese Academy of Sciences in Beijing and her colleagues have identified the substance as a kind of kefir cheese.


A thousands-year-old log demonstrates how burying wood can fight climate change

A thousands-year-old log demonstrates how burying wood can fight climate change

If the conditions that preserved the Canadian log can be replicated — which is still unclear — buried biomass from discarded wood and sustainable harvesting could sequester up to 10 gigatons of carbon annually, the researchers estimate.

For instance, Ophir automated his analysis of over 5,000 articles about the H1N1, Ebola and Zika epidemics in four major newspapers: the New York Times, Washington Post, USA Today and Wall Street Journal.


Some healthy fish have bacteria in their brains

Some healthy fish have bacteria in their brains

Lab-reared rainbow trout (Oncorhynchus mykiss) brains may source more than half of bacteria from their blood and guts, suggesting that microbes from other parts of the body traverse the blood-brain barrier to colonize the organ.

How to spot tiny black holes that might pass through the solar system

Other effects that could tweak planetary orbits would also need to be accounted for, such as the solar wind of charged particles that streams out from the sun, says astrophysicist Andreas Burkert of Ludwig-Maximilians-UniversitĂ€t MĂŒnchen in Germany, who was not involved with the two studies.

‘Shazam for whales’ uses AI to track sounds heard in Mariana Trench

Allen saw an opportunity to track migrating Bryde’s whales by finding similar biotwang sounds in more than 180,000 hours of underwater recordings from NOAA’s network of hydrophones mounted on the Pacific seafloor.
