| Can life survive a star's death? Webb telescope can reveal the answer Posted: 16 Sep 2020 08:36 AM PDT When stars like our sun die, all that remains is an exposed core -- a white dwarf. A planet orbiting a white dwarf presents a promising opportunity to determine if life can survive the death of its star, according to researchers. |
| Security software for autonomous vehicles Posted: 16 Sep 2020 08:36 AM PDT Before autonomous vehicles participate in road traffic, they must demonstrate conclusively that they do not pose a danger to others. New software prevents accidents by predicting different variants of a traffic situation every millisecond. |
| Enormous planet quickly orbiting a tiny, dying star Posted: 16 Sep 2020 08:35 AM PDT Thanks to a bevy of telescopes in space and on Earth -- and even a pair of amateur astronomers in Arizona -- astronomers have discovered a Jupiter-sized planet orbiting at breakneck speed around a distant white dwarf star. |
| World's largest DNA sequencing of Viking skeletons reveals they weren't all Scandinavian Posted: 16 Sep 2020 08:35 AM PDT Invaders, pirates, warriors - the history books taught us that Vikings were brutal predators who travelled by sea from Scandinavia to pillage and raid their way across Europe and beyond. Now cutting-edge DNA sequencing of more than 400 Viking skeletons from archaeological sites scattered across Europe and Greenland will rewrite the history books. |
| Next-gen organoids grow and function like real tissues Posted: 16 Sep 2020 08:35 AM PDT Bioengineers have created miniature intestines in a dish that match up anatomically and functionally to the real thing better than any other lab-grown tissue models. The biological complexity and longevity of the new organoid technology is an important step towards enabling drug testing, personalized medicine, and perhaps, one day, transplantations. |
| Brain circuitry underlying dissociative experiences Posted: 16 Sep 2020 08:35 AM PDT Scientists identified key brain circuitry that plays a role in the mysterious experience called dissociation, in which people can feel disconnected from their own body and from reality. |
| Scientist searches for stellar phosphorus to find potentially habitable exoplanets Posted: 16 Sep 2020 08:35 AM PDT A scientist has identified stellar phosphorus as a probable marker in narrowing the search for life in the cosmos. She has developed techniques to identify stars likely to host exoplanets, based on the composition of stars known to have planets, and proposes that upcoming studies target stellar phosphorus to find systems with the greatest probability for hosting life as we know it. |
| Liquid water at 170 degrees Celsius Posted: 16 Sep 2020 08:35 AM PDT Using an X-ray laser, a research team has investigated how water heats up under extreme conditions. In the process, the scientists were able to observe water that remained liquid even at temperatures of more than 170 degrees Celsius. The investigation revealed an anomalous dynamic behavior of water, which is of fundamental importance for investigations of sensitive samples using X-ray lasers. |
| Device could help detect signs of extraterrestrial life Posted: 16 Sep 2020 08:34 AM PDT Although Earth is uniquely situated in the solar system to support creatures that call it home, different forms of life could have once existed, or might still exist, on other planets. But finding traces of past or current lifeforms on other worlds is challenging. Now, researchers have developed a fully automated microchip electrophoresis analyzer that, when incorporated into a planetary rover, could someday detect organic biosignatures in extraterrestrial soil. |
| Did our early ancestors boil their food in hot springs? Posted: 15 Sep 2020 12:24 PM PDT Scientists have found evidence of hot springs near sites where ancient hominids settled, long before the control of fire. |
| Elements of surprise: Neutron stars contribute little, but something's making gold Posted: 15 Sep 2020 08:00 AM PDT Neutron star collisions do not create the quantity of chemical elements previously assumed, a new analysis of galaxy evolution finds. The research also reveals that current models can't explain the amount of gold in the cosmos - creating an astronomical mystery. The work has produced a new-look Periodic Table, showing the stellar origins of naturally occurring elements from carbon to uranium. |
