ENVIRONMENT & CLIMATEIn an attempt to understand the social dynamics among our hunter-gatherer ancestors, anthropologists sometimes begin in the present and work backwards. And what the researchers at University College London have found adds another dimension to the unique social structure of hunter-gatherer society.
It was once believed that tool use was one of the signifying traits distinguishing humans from the rest of the animal world, but research has shown that is simply not the case. Chimps crack nuts, gorillas build rudimentary bridges, and dolphins use sponges to stir up the ocean floor, just to name a few. Scientists can now add macaques to the list, for it turns out they are quite handy with a hammer.
Research has proven that rats place more value on saving others than obtaining a food reward. Rats, especially those who have nearly drowned in the past, will resuce each other from drowning. They experience a kind of empathy.
A Massey University research team has discovered some interesting new truths about the ways arranged marriages affect genetic diversity and the ways that humans follow even important cultural rules selectively-and they may surprise you. The results show that the isolated Indonesian Rindi tribe produces genetic diversity similar to random mating by loosely complying with their rules which mandate arranged, inbred marriages.
Honeybees are dying en masse all over the globe, and it's not just lovers of honey that should be concerned. These mass deaths will change our dinner plates forever, not to mention raise the cost of eating generally. In a world where food security and hunger are crucially important, this is bad news for everyone.
One of the latest breakthroughs from Yale scientists: the mighty dino-chicken. The Yale team used molecular manipulation to grow chicken embryos with Velociraptor snouts and published their results yesterday in the journal Evolution. The embryos did not hatch.
Anyone who knows paleontology, knows the older the sediment, the greater the potential for documenting the evolution of life on earth. I guess the same can be said of certain naturalists, namely David Attenborough, who has been exploring life on our planet for almost 90 years.
In the midst of digging out from the magnitude 7.8 quake that struck Nepal just three weeks ago, residents of Kathmandu find themselves once again in recovery mode. A powerful aftershock, with a preliminary magnitude registering 7.3, struck just east of Nepal's capital on Tuesday, sending an already rattled community running for cover yet again.
For over twenty years, scientists have used modern technology, in the form of CT scans and X-rays, to virtually unwrap mummified remains. These powerful tools, which allow researchers to peer inside mummies, provide information as to cause of death, burial treatment, and individual traits of the deceased. But now, this technology is being used to explore a new breed of Egyptian mummies: animals that were preserved to accompany the dead. And perhaps the greatest surprise is what's missing from these mummified treasures.
Technology from NASA's Jet Propulsion Laboratory (JPL) helped search-and-rescue teams find and save four men buried in rubble following the Nepal Earthquake. FINDER, a device no larger than a carry-on suitcase weighing less than 20 pounds, detected the heartbeats of the victims through 10 feet of wood, mud, and brick.
The latest human first has chilling consequences for our species, and all others: for the first time since scientists began tracking global carbon dioxide concentrations in our atmosphere, we have surpassed 400 parts per million worldwide.
It's not as colorful in an action movie as invaders from other galaxies, for example, but it seems that soil erosion might be just as deadly to humans. Scientists from the University of California, Berkeley warn that human food security is at risk from the accelerating rate of soil depletion.
The folks in Oklahoma City are waking up to a city ransacked by a bevy of storms that swept through the Midwest yesterday, sparking twisters that ripped through parts of Kansas, Nebraska, and Texas on Wednesday night.
In the search for the origins of life, scientists have found a striking new link between lone cells and complex creatures like humans. The connection comes from observing life under the harsh conditions that exist near volcanoes more than a mile below the surface of the Atlantic Ocean.
