| New galaxy images reveal a fitful start to the Universe Posted: 20 Oct 2021 05:37 PM PDT New images have revealed detailed clues about how the first stars and structures were formed in the Universe and suggest the formation of the Galaxy got off to a fitful start. |
| First dinosaur era crab fully preserved in amber discovered Posted: 20 Oct 2021 12:02 PM PDT Researchers describe the first crab from the Cretaceous dinosaur era preserved in amber. The study used micro CT to examine and describe Cretapsara athanata, the oldest modern-looking crab (approximately 100 million years old) and the most complete fossil crab ever discovered. |
| Researchers make hardened wooden knives that slice through steak Posted: 20 Oct 2021 10:59 AM PDT The sharpest knives available are made of either steel or ceramic, both of which are human-made materials that must be forged in furnaces under extreme temperatures. Now, researchers have developed a potentially more sustainable way to make sharp knives: using hardened wood. The method makes wood 23 times harder and a knife made from the material is nearly three times sharper than a stainless-steel dinner table knife. |
| Europeans in the Americas 1000 years ago Posted: 20 Oct 2021 10:59 AM PDT The Vikings were active in North America in the year 1021 AD. This now represents the earliest -- and only -- known year in which Europeans were present in the Americas prior to the arrival of Columbus in 1492 AD. It also represents a definitive point in time by which the Atlantic Ocean had been traversed and human migration had finally encircled the globe. |
| Astronomers detect signs of an atmosphere stripped from a planet in a giant impact Posted: 20 Oct 2021 10:59 AM PDT A team has discovered evidence of a giant impact in the nearby HD 17255 star system, in which an Earth-sized terrestrial planet and a smaller impactor likely collided at least 200,000 years ago, stripping off part of one planet's atmosphere. |
| Lightweight electric wristband heaters for constant, portable warmth Posted: 20 Oct 2021 10:59 AM PDT As the fall chill settles in across the U.S., people are getting out their cozy sweaters and electric blankets, or stocking up on handheld heat packets for extra warmth. But sweaters and blankets are bulky, and heat packs only work for a little while. Now, researchers demonstrate a conductive, durable yarn for lightweight wearable heaters that are re-usable and provide constant, portable warmth. |
| Plugging into ocean waves with a flexible, seaweed-like generator Posted: 20 Oct 2021 10:58 AM PDT Ocean waves can be powerful, containing enough energy to push around sand, pebbles and even boulders during storms. These waves, as well as smaller, more gentle ones, could be tapped as a source of renewable energy. Now, researchers have developed flexible power generators that mimic the way seaweed sways to efficiently convert surface and underwater waves into electricity to power marine-based devices. |
| Cat bacteria treats mouse skin infection, may help you and your pets as well Posted: 19 Oct 2021 09:35 AM PDT Researchers identify a strain of bacteria on healthy cats that produces antibiotics against severe skin infections. The findings may soon lead to new bacteriotherapies for humans and their pets, wherein cat bacteria is applied via topical cream or spray. |
| Amount of information in visible universe quantified Posted: 19 Oct 2021 09:01 AM PDT Researchers have long suspected a connection between information and the physical universe, with various paradoxes and thought experiments used to explore how or why information could be encoded in physical matter. A researcher attempts to shed light on exactly how much of this information is out there and presents a numerical estimate for the amount of encoded information in all the visible matter in the universe -- approximately 6 times 10 to the power of 80 bits of information. |
