New evidence of 'human' culture among primates

...at these monkey populations use stones as tools to dig holes or to forage and questions remain about why this happens in this area. Because it is quite dry and barren, it is possible they learn these skills from one another because they have to develop them quickly. To be sure we would need to research m...

Dig deeper to find Martian life

...he current probes is slim. Scientists will need to dig deeper and target very specific, hard-to-reach areas such as recent craters or areas where water has recently surfaced. Dr Andrew Coates, UCL Department of Space & Climate Physics, said: "This study is trying to understand the radiation envir...

Researchers give name to ancient mystery creature

...bout 10 years ago, more teeth were discovered at a dig site near Drayton Valley and on the banks of the Blindman. But the creature mystified the researchers, who could not positively identify it, and exactly where it fits into the evolutionary ladder is still unknown. Horolodectes remains an enigma to th...

Paying attention sets off symphony of cell synchronization

...r behavior," Grabowecky said. "When you need to dig deep to summon that extra ounce of attention, it's as if you engage a symphony of brain activity that can come to your rescue as millions of neurons together make the music that represents a vivid conscious experience," added Ken Paller, professor of...

Exxon Valdez oil found in tidal feeding grounds of ducks, sea otters

...t least once every two months. However, sea otters dig thousands of pits a year, and Short suspects they actually could be encountering oil far more often than estimated. ...

Leave it to salmon to leave no stone unturned

...in years when salmon populations are high, sockeye dig up entire stream beds more than once, being forced to superimpose new nests on top of old nests when the females run out of room. Moore's work and the UW's Alaska Salmon Program is funded by the National Science Foundation, the Gordon and Betty Moor...

Darkness unveils vital metabolic fuel switch between sugar and fat

...What actually sets off hibernation? "These animals dig deep burrows," said Lee, an expert in circadian rhythms. "They are constantly in the dark. Why not darkness as a switch?" Mice do not hibernate but they can slip into a similar short-term state of torpor. Lee and colleagues started with a microar...

Mining for gems in the fungal genome

... "genomic mining" because of its robust ability to dig through an entire fungal genome to locate nearly all the hidden gems-the actively-produced secondary metabolites-at once. The key to Keller's approach lies in a single fungal protein called LaeA. A few years ago, her team discovered that the pres...

Small species back-up giant marsupial climate change extinction claim

...e stratification of fossils in the creek bed. The dig also failed to unearth evidence of human activity, suggesting they didn't inhabit the region at the same time as megafauna. Queensland Museum Assistant Curator in Geosciences, Scott Hocknull added: "We're not just digging up a pile of old bones. Th...

Introduced foxes transformed vegetation on Aleutian Islands from lush grasslands to tundra

... the ground; burrow nesters, such as puffins, that dig burrows in the soil for their nests; and crevice nesters, such as auklets, that nest in boulder piles and rock crevices. According to Byrd, surface nesters and burrow nesters tended to disappear completely from islands with foxes, while populations ...

Gene therapy converts dead bone graft to new, living tissue

...rain and heart, runs low, cells called osteoclasts dig out the calcium from our bones. This is why doctors encourage post-menopausal women to take calcium supplements, so that the body doesn't raid their bones for the calcium it needs. The process works both ways, fortunately, as another set of cells, ca...
