Feral camels in the Australian outback are reviled as pests. Yet they thrive, totaling some one million strong.

How did they go from historic helper to overbearing invader? As usual, numbers make the difference. 

The deserts of the Australian outback are a notoriously inhospitable environment where few species can survive - but camels can. The dromedary camel (Camelus dromedarius) prospers where others perish, eating 80% of native plant species and obtaining much of their water through ingesting this vegetation.

Modern Western parents spend a lot of time trying to figure out new ways for kids not to be kids and to force their behavior into narrow ranges. Then modern Western spend a lot of time filling out surveys saying they want their kids to be intelligent, creative and independent. 

If you are a parent who wants to mollify the animalistic eating behavior of your child, don't give them a chicken drumstick, cut their food into little pieces for them. Yes, whole foods are causing bad behavior, according to a new paper.

Basketball is a popular high school sport in the United States with 1 million participants annually. A recently published study by researchers in the Center for Injury Research and Policy at Nationwide Children's Hospital is the first to compare and describe the occurrence and distribution patterns of basketball-related injuries treated in emergency departments and the high school athletic training setting among adolescents and teens.

Neuroscientists have discovered a brain pathway that underlies the emotional behaviours critical for survival.

New research by the University of Bristol, published in the Journal of Physiology today [23 April], has identified a chain of neural connections which links central survival circuits to the spinal cord, causing the body to freeze when experiencing fear.

Understanding how these central neural pathways work is a fundamental step towards developing effective treatments for emotional disorders such as anxiety, panic attacks and phobias.

Cougars may have survived the mass extinction that took place about 12,000 years ago because they were not particular about what they ate, unlike their more finicky cousins--the saber-tooth cat and American lion. Both perished along with the woolly mammoth and many of the other supersized mammals that walked the Earth during the late Pleistocene.

That is the conclusion of a new analysis of the microscopic wear marks on the teeth of cougars, saber-tooth cats and American lions described in the April 23 issue of the journal Biology Letters.

Inspired by the fist-like club of a mantis shrimp, researchers have developed a design structure for composite materials that is more impact resistant and tougher than the standard used in airplanes.

The peacock mantis shrimp, or stomatopod, is a 4- to 6-inch-long rainbow-colored crustacean with a fist-like club that accelerates underwater faster than a 22-caliber bullet. Researchers, led by Kisailus, an associate professor of chemical engineering, are interested in the club because it can strike prey thousands of times without breaking.
