They’re called trans-Neptunian objects, or TNOs. Astronomers analyzed data from the Dark Energy Survey – which just completed 6 years of observations – to find over 100 new little worlds in the cold outer reaches of our solar system.
Scientists Discover a Complete Protein Found Nowhere on Earth That Fell From Space, May Hint at Planetâs Origin
On a meteorite, scientists believe they have discovered the first complete extraterrestrial protein that could define life’s origins on earth.
Because of poor dates for land fossils laid down before and after the mass extinction at the end of the Permian, paleontologists assumed that the terrestrial extinctions from Gondwana occurred at the same time as the better-documented marine extinctions. But a new study provides more precise dates for South African fossils and points to a long, perhaps 400,000-year period of extinction on land before the rapid marine extinction 252 million years ago.
One of the most widely used oil-based plastics, polyurethane, is particularly hard to recycle or destroy safely. It also releases toxic chemicals into landfills. However, some microorganisms are capable of metabolizing these compounds and degrading the plastic waste in the process. Scientists have identified one such bacterium that could be used to help break down polyurethane-based plastics for future bio-recycling.
“We took ketchup.” This is the only food Karl Bretzendorfer remembers taking up to the attic where he spent 13 days trapped with his wife Irina, as the waters rose around them in what Chancellor Angela Merkel called “the flood…
Our body’s ability to detect disease, foreign material, and the location of food sources and toxins is all determined by a cocktail of chemicals that surround our cells, as well as our cells’ ability to ‘read’ these chemicals. Cells are highly sensitive. In fact, our immune system can be triggered by the presence of just one foreign molecule or ion. Yet researchers don’t know how cells achieve this level of sensitivity.
