Fused nasal bones helped tyrannosaurids dismember prey

... whose finding demonstrates how a fused nasal bone helped turn the animal into a "zoological superweapon." ...d the strength of such dinosaurs as the T. rex and helped them apply powerful bites that could splinter bone. With other carnivorous dinosaurs, says Snively, ...

Why do oysters choose to live where they could be eaten?

...lt oysters and how larvae actively settle on reefs helped solved the puzzle. Oyster feeding currents are actually very weak, so while they will readily eat larvae if captured, settling larvae are just not captured very often. In fact, when a comparison of being captured versus landing on a suitable location...

Lessons from the orangutans: Upright walking may have begun in the trees

...r balance, or "hand-assisted bipedalism," may have helped them travel on these branches. The researchers analyzed nearly 3,000 examples of observed orangutan movement, and found that the orangutans were more likely to use hand-assisted bipedalism when they were on the thinnest branches. When bipedal, the...

How brain pacemakers erase diseased messages

Brain "pacemakers" that have helped ease symptoms in people with Parkinson's disease and other movement disorders seem to work by drowning out the electrical signals of their diseased brains. Despite the clinical success of the devices, which have been approved by the Food and Drug Ad...

Staphylococcus aureus hides out in cells

...ntrolled to limit cellular damage. Mechanisms that helped the bacteria to survive and/or multiply, including metabolic and energy production functions, then resumed. Although most of the bacteria had died by about four days as a result of antibiotic treatment, the team still found viable bacteria in their m...

Brain holds clues to bipolar disorder

...riefing held at 12:15 p.m., Thursday, June 7, have helped to identify novel pathways and markers for diagnosis and treatment of the disease. The first study, presented by Husseini K. Manji, M.D., chief of the Laboratory of Molecular Pathophysiology at the National Institute of Mental Health (NIMH), suggest...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...n death from malaria. Earlier this year, they also helped describe how the gene PfNHE likely contributes, and this turns out not to be as vital as PfCRT. Now, based in part on this study, they know that PfMDR1 is dependent on mutated PfCRT, and probably doesn't act independently. "The contribution of Pf...

Genomic Analysis Uncovers New Targets for HIV Vaccine

...f 486 people infected with HIV that appear to have helped some of the patients fight off the virus and delay the onset of full-blown AIDS. The researchers expect the new findings to aid the search for an HIV vaccine that would work by boosting the protective effects of one or more of these genes, and help ...
