The Trap-Jaws’ Mighty Mandibles Propel Them from Danger

The mighty mandibles of the trap-jaw ants are legendary in the animal kingdom. Members of the genus Odontomachus have specialized spring-loaded jaws that can snap shut at speeds of 60 meters per second, with forces that exceed 300 times their body weight. But in four species, those powerful jaws are not only great at catching prey, they can also aid in the ant's escape.

Macaques Prove Quite Handy with a Hammer

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.

All In The Family: Arranged Marriages And Genetic Diversity

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.

Meet Velociraptor’s ‘Nosey’ Cousin

Paleontologists have recently identified a new member of the raptor family, one that may have had a leg up on its competition: a keen sense of smell.

Embryological Manipulation Reveals Chicks Can Have Prehistoric Looks

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.

Attenborough, and the Evolution of Life, Continue to Intrigue

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.

Fierce Aftershock Compounds Recovery Efforts in Nepal

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.

Egyptian Mummified Animals Contain Hidden Surprises

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.

JPL Tech In Space And On Ground Helps Save Lives After Disaster

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.

How's the Carbon Stacking Up? NOAA Says CO2 Has Passed Its Mark

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.
