HIV and malaria combine to adversely affect pregnant women and their infants

.... To uncover how HIV affects PAM, Kain and his team collected samples from women in the first pregnancy as well as from women in their subsequent ones living in the Kenyan region where malaria is common. The researchers demonstrated that protection to PAM is mediated by a special type of antibody that...

Common treatment for methamphetamine overdose may damage brain cells

... alone. Senior author Bryan Yamamoto, PhD, and his team at Boston University School of Medicine suspect the damage results from the exaggerated stimulation of cells by the amino acid glutamate, which proves toxic to cells producing the neurotransmitter gamma-aminobutyric acid (GABA). Their results are pub...

For many insects, winter survival is in the genes

Detecting cold, feeling pain: Study reveals why menthol feels fresh

...The finding is a milestone in an investigation the team began several years ago. In 2002, the researchers ...estioned this theory. In the current study, the team confirmed their hypothesis by "knocking out" the gene that synthesizes the receptor, both in sensory...

Better insight into brain anatomical structures

...e, strokes, and tumors. Furthermore, the Korean team was able to attach antibodies to the manganese oxide nanoparticles. These antibodies recognize and specifically bind to receptors on the surface of breast cancer cells. In mouse brains with breast cancer metastases, the tumors were clearly highlighte...

NASA-funded robotic sub finds bottom of world's deepest sinkhole

...meter, included 56 sonars that the Carnegie Mellon team used to determine the location of the vehicle as it explored the cenote. It also used the sensors to create maps of the sinkhole’s interior via a technique called simultaneous localization and mapping, or SLAM. Prior to the DEPTHX field experiment, S...

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

By observing wild orangutans, a research team has found that walking on two legs may have arisen in relatively ancient, tree-dwelling apes, rather than in more recent human ancestors that had already descended to the savannah, as current theory suggests. These findings appear in the 1 June 20...

Pistachios lower cholesterol, provide antioxidants

...etables and brightly colored fruit, according to a team of researchers. "Pistachio amounts of 1.5 ounces and 3 ounces ?one to two handfuls ?reduced risk for cardiovascular disease by significantly reducing LDL cholesterol levels and the higher dose significantly reduced lipoprotein ratios," says Sarah K....

As a result, they went further and also made a social inventory based on interviews with local forest officials and villagers. This inventory revealed that loss of forest occ...

'Personality-gene' makes songbirds curious

...o have different personalities. An international team of researchers have now found evidence for the existence of a "curiosity-gene" in a songbird, the great tit (Parus major). The gene (Drd4) carries the building instructions for a receptor in the brain, which forms the docking station for the neurotra...

Scripps research team sheds light on long-sought cold sensation gene

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

...cle in the May edition of Ecological Monographs, a team of scientists has found that despite the risk of being eaten by cannibalistic adults, oyster larvae choose to settle in areas of high oyster concentrations to take advantage of future benefits of increased reproductive capacity when they mature.

The team find their music more melodic and less ‘jumpy?than previous attempts, which have focussed on DNA sequences and protein folding, and hence closer to the musical depth of popular compositions. They are currently piloting a computer program, written by ...
