| First contracting human muscle grown in laboratory Posted: 13 Jan 2015 12:40 PM PST Researchers have grown human skeletal muscle in the laboratory that, for the first time, contracts and responds just like native tissue to external stimuli such as electrical pulses, biochemical signals and pharmaceuticals. The development should soon allow researchers to test new drugs and study diseases in functioning human muscle outside of the human body. |
| Feeling cold is contagious, scientists find Posted: 13 Jan 2015 11:52 AM PST Just looking at somebody shivering is enough to make us feel cold, new research has found. Volunteers who watched videos of people putting their hands in cold water found their own body temperature drop significantly, investigators report. |
| Nothing to squirm about: Space station worms help battle muscle, bone loss Posted: 13 Jan 2015 09:11 AM PST Two investigations on the space station help researchers seek clues to physiological problems found in astronauts by studying C. elegans -- a millimeter-long roundworm that is widely used as a model organism. This simple, tiny roundworm could lead to a cure for symptoms affecting millions of the aging and infirm population of Earth, and the astronauts orbiting it, potentially offering a solution to a major problem in an extremely small package, scientists say. |
| Posted: 13 Jan 2015 09:10 AM PST Two and a half million years ago, our hominin ancestors in the African savanna crafted rocks into shards that could slice apart a dead gazelle, zebra or other game animal. Over the next 700,000 years, this butchering technology spread throughout the continent and, it turns out, came to be a major evolutionary force. |
| Brazilian scarab beetles found to be termitophiles Posted: 13 Jan 2015 08:14 AM PST An international team of scientists has provided the first record of chafer leaf beetles (Leucothyreus suturalis) living in the nests of two different termite species in Brazil. |
| Surprise discovery off California exposes loggerhead 'lost years' Posted: 13 Jan 2015 08:14 AM PST North Pacific loggerhead turtles hatch in Japan, with many later reappearing 6,000 miles away off southern Baja California to forage. The sighting late last year of numerous young turtles far off the Southern California Coast provides new insight into their their epic migration across the Pacific Ocean. |
| Robots learn to use kitchen tools by watching YouTube videos Posted: 13 Jan 2015 06:06 AM PST Robotic systems that are able to teach themselves have been developed by researchers. Specifically, these robots are able to learn the intricate grasping and manipulation movements required for cooking by watching online cooking videos. The key breakthrough is that the robots can 'think' for themselves, determining the best combination of observed motions that will allow them to efficiently accomplish a given task. |
| Sizing up giants under the sea: Biologists correct inaccuracies for 25 marine species Posted: 13 Jan 2015 06:05 AM PST Researchers sifted through multiple datasets and historical records to produce more accurate and comprehensive measurements for 25 species including the Blue Whale, Giant Squid, and Great White Shark. |
| Species of bird 'paints' its own eggs with bacteria to protect embryo Posted: 13 Jan 2015 06:04 AM PST Hoophoes cover their eggs with a secretion produced by themselves, loaded with mutualistic bacteria, which is then retained by a specialized structure in the eggshell that increases successful hatching. So far this sort of behavior has only been detected in this species of birds, and it is a mechanism to protect their eggs from infections by pathogens. |
