Taung Child's brain development not human-like? CT scan casts doubt on similarity to that of modern humans Posted: 25 Aug 2014 12:25 PM PDT By subjecting the skull of the famous Taung Child to the latest CT scan technology, researchers are now casting doubt on theories that Australopithecus africanus shows the same cranial adaptations found in modern human infants and toddlers.

Scientists grow an organ in an animal from cells created in lab Posted: 25 Aug 2014 07:00 AM PDT Scientists have grown a fully functional organ from transplanted laboratory-created cells in a living animal for the first time. The researchers have created a thymus -- an organ next to the heart that produces immune cells known as T cells that are vital for guarding against disease.

Are you as old as what you eat? Researchers learn how to rejuvenate aging immune cells Posted: 24 Aug 2014 12:23 PM PDT Researchers have demonstrated how an interplay between nutrition, metabolism and immunity is involved in the process of aging. It has been suspected for a long time that these are linked, and this paper provides a prototype mechanism of how nutrient and senescence signals converge to regulate the function of T lymphocytes.

Fungus deadly to AIDS patients found to grow on trees Posted: 22 Aug 2014 05:40 AM PDT Researchers have pinpointed the environmental source of fungal infections that have been sickening HIV/AIDS patients in Southern California for decades. It literally grows on trees. The discovery is based on the science project of a 13-year-old girl, who spent the summer gathering soil and tree samples from areas around Los Angeles hardest hit by infections of the fungus named Cryptococcus gattii (CRIP-to-cock-us GAT-ee-eye).

Fish and coral smell a bad neighborhood: Marine protected areas might not be enough to help overfished reefs recover Posted: 21 Aug 2014 11:13 AM PDT Pacific corals and fish can both smell a bad neighborhood, and use that ability to avoid settling in damaged reefs. Damaged coral reefs emit chemical cues that repulse young coral and fish, discouraging them from settling in the degraded habitat, according to new research. The study shows for the first time that coral larvae can smell the difference between healthy and damaged reefs when they decide where to settle.

Area of brain responsible for exercise motivation discovered Posted: 20 Aug 2014 01:43 PM PDT An area of the brain that could control a person's motivation to exercise and participate in other rewarding activities -– potentially leading to improved treatments for depression -- has been discovered by researchers. "Changes in physical activity and the inability to enjoy rewarding or pleasurable experiences are two hallmarks of major depression," one researcher said.
