| Erectile dysfunction drug may benefit patients at risk for diabetes Posted: 18 Nov 2015 03:05 PM PST The drug sildenafil, sold as Viagra and other brand names, improves insulin sensitivity in people at risk for diabetes, researchers report. |
| Neurogastronomy: How our brains perceive the flavor of food Posted: 18 Nov 2015 01:06 PM PST Neuroscientists, food scientists and internationally-renowned chefs convened at the University of Kentucky recently to explore ways to help patients with neurologically-related taste impairments enjoy food again. |
| What salamanders can teach us about baseball Posted: 18 Nov 2015 01:01 PM PST Researchers have increased our understanding of how people and animals deal with sensorimotor delay in day-to-day interactions by analyzing the hunting skills of salamanders. |
| Posted: 18 Nov 2015 01:01 PM PST A new study has found pigeons performed as well as humans in categorizing digitized slides and mammograms of benign and malignant human breast tissue. |
| Our closest wormy cousins: About 70% of our genes trace their ancestry back to the acorn worm Posted: 18 Nov 2015 12:51 PM PST Scientists have analyzed the genomes of two acorn worm species and found that approximately two-thirds of human genes have counterparts in the ancestors of these marine animals. These ancient genes, and their organization within the genome, were already in place in the common ancestor of humans and acorn worms that lived over half a billion years ago. |
| Smeagol found underground in Brazil: New eyeless and highly modified harvestman species Posted: 18 Nov 2015 09:53 AM PST Called after Tolkien's character from the 'Lord of the Rings' series, a new eyeless harvestman species was found to crawl in a humid cave in southeastern Brazil. Never getting out of its subterranean hiding, the new daddy longlegs species is the most highly modified representative among its close relatives and only the second one with no eyes living in Brazil. |
| Cereal science: New phenomenon in materials science observed in compaction of puffed rice cereal Posted: 18 Nov 2015 07:17 AM PST There's more to the snap, crackle and pop of Rice Krispies than meets the ear. A recent study used the breakfast cereal to discover a new phenomenon in materials science: highly porous, brittle materials can deform in different ways depending on compaction velocity ... the discovery could have implications for manufacturing or even assessing the safety of snow after an avalanche. |
| Why mice have longer sperm than elephants Posted: 18 Nov 2015 04:14 AM PST In the animal world, if several males mate with the same female, their sperm compete to fertilize her limited supply of eggs. Longer sperm often seem to have a competitive advantage. However, a study now reveals that the size of the animals also matters. The larger the animal, the more important the number of sperm is relative to sperm length. That's why elephants have smaller sperm than mice. |
| High-performance swimsuit developed: 2.4% faster swimming with the dolphin kick Posted: 18 Nov 2015 04:11 AM PST Researchers have succeeded in developing a new high-performance swimsuit with a "kick assist system" that improves the power of the dolphin kick. High-speed swimsuits, which made their appearance at the 2008 Olympics in Beijing, were the driving force behind a barrage of new world records. However, the International Swimming Federation changed the rules significantly in 2010 due to a concern that swimming races were not being won by superior swimming techniques but by superior swimsuits, and the ruling body imposed strict regulations. These restrictions greatly narrowed the scope of swimsuit development and all but eliminated hope for improving swimsuit performance. To make a breakthrough under these conditions, the research group went back to the drawing board and put their heads together to figure out what exactly about a swimsuit allows a swimmer to go faster. |
| Radiation blasts leave most Earth-like planet uninhabitable Posted: 18 Nov 2015 04:10 AM PST The most Earth-like planet could have been made uninhabitable by vast quantities of radiation.The atmosphere of the planet, Kepler-438b, is thought to have been stripped away as a result of radiation emitted from a superflaring red dwarf star, Kepler-438. Regularly occurring every few hundred days, the superflares are approximately 10 times more powerful than those ever recorded on the sun and equivalent to the same energy as 100 billion megatons of TNT. |
| Earliest giant galaxies: The birth of monsters Posted: 18 Nov 2015 04:07 AM PST ESO's VISTA survey telescope has spied a horde of previously hidden massive galaxies that existed when the universe was in its infancy. By discovering and studying more of these galaxies than ever before, astronomers have, for the first time, found out exactly when such monster galaxies first appeared. |
