| A little squid and its glowing bacteria yield new clues to symbiotic relationships Posted: 09 Mar 2021 12:38 PM PST The relationship between the Hawaiian bobtail squid and the bioluminescent bacteria living in its light organ has been studied for decades as a model of symbiosis. Now researchers have used a powerful chemical analysis tool to identify a small molecule produced by the bacteria that appears to play an important role in their colonization of the light organ. |
| Gigantic jet spied from black hole in early universe Posted: 09 Mar 2021 12:35 PM PST Astronomers have discovered evidence for an extraordinarily long jet of particles coming from a supermassive black hole in the early universe. |
| Breaking the warp barrier for faster-than-light travel Posted: 09 Mar 2021 10:25 AM PST If travel to distant stars within an individual's lifetime is going to be possible, a means of faster-than-light propulsion will have to be found. To date, even recent research about faster-than-light transport would require vast amounts of hypothetical particles and states of matter that have 'exotic' physical properties. New research gets around this problem by constructing a new class of hyper-fast 'solitons.' |
| Posted: 09 Mar 2021 08:44 AM PST From ice skating, it has been known for a long time that a thin liquid film forms on ice surfaces. This, along with other causes, is responsible for ice slipperiness. Scientists have now investigated a related effect at interfaces between ice and porous clay minerals. Such interfaces are found in nature for example in permafrost. The results may help to better understand changes in frozen soils as temperatures rise. |
| Younger Tyrannosaurus Rex bites were less ferocious than their adult counterparts Posted: 09 Mar 2021 08:43 AM PST By closely examining the jaw mechanics of juvenile and adult tyrannosaurids, some of the fiercest dinosaurs to inhabit earth, scientists have uncovered differences in how they bit into their prey. |
| First infection of human cells during spaceflight Posted: 09 Mar 2021 08:43 AM PST Scientists have described the infection of human cells by the intestinal pathogen Salmonella Typhimurium during spaceflight. They show how the microgravity environment of spaceflight changes the molecular profile of human intestinal cells and how these expression patterns are further changed in response to infection. The researchers were also able to detect molecular changes in the bacterial pathogen while inside the infected host cells. |
| Engineers propose solar-powered lunar ark as 'modern global insurance policy' Posted: 09 Mar 2021 07:51 AM PST Researchers are taking scientific inspiration from an unlikely source: the biblical tale of Noah's Ark. Rather than two of every animal, however, his solar-powered ark on the moon would store cryogenically frozen seed, spore, sperm and egg samples from 6.7 million Earth species. The proposed structure would be built within the moon's enormous, underground lava tubes, which have been untouched for billions of years. |
| 'Wearable microgrid' uses the human body to sustainably power small gadgets Posted: 09 Mar 2021 06:13 AM PST This shirt harvests and stores energy from the human body to power small electronics. UC San Diego nanoengineers call it a ''wearable microgrid''-- it combines energy from the wearer's sweat and movement to provide sustainable power for wearable devices. |
| Posted: 08 Mar 2021 08:19 AM PST A coordinated conservation effort that removed rats from Hawadax Island, formerly known as 'Rat Island,' has become a new example of how ecosystems can fully recover to their natural state in little more than a decade. |
| Virtual avatar coaching with community context for adult-child dyads Posted: 08 Mar 2021 05:42 AM PST Virtual reality avatar-based coaching shows promise to increase access to and extend the reach of nutrition education programs to children at risk for obesity, according to a new study. |
