8 plants from South Africa may hold potential for treating high blood pressure

...nts, rheumatism and high fevers. Other researchers found (1966) that native South Africans rubbed the leaves of the plant on the head for sinus headaches and used plant infusions for colic and restlessness in young children. The most direct discovery is the 1993 finding that large doses of popular garlic p...

A frown or a smile? Children with autism can't discern

...th the typically developing group, the researchers found significant differences in activity in a part of the brain called the ventrolateral prefrontal cortex (VLPFC), which is known to play a role in evaluating emotions. While these children looked at the direct-gaze faces, the VLPFC became active; with t...

Brain's white matter -- More 'talkative' than once thought

...wo brain hemispheres. To their surprise, OPCs were found to have electrical signals produced by the neurotransmitter glutamate, similar to the signals used as the principle means of cell-to-cell communication and information processing in the gray matter. The phenomenon was unlikely, they said, because in ...

An ancient bathtub ring of mammoth fossils

...exceptions rather than the rule. Full skeletons found at lower elevations were likely buried soon after death-by-torrent, a hard to imagine wall of water a half-mile high spanning the doomed creature’s entire field of vision and approaching as fast as 60 miles an hour. Some fragments may have come from ...

Anthrax paralyzes immune cells with lethal toxin, UF research shows

...oward an infection. In a previous study, Southwick found that the toxin prevents actin assembly, leaving neutrophils stuck in the mud. "Actin is important because it's the motor that causes neutrophils to move," said Southwick. "So it's like cutting the gas to the motor." Anthrax literally cuts the g...

"This is apparently a fundamental, evolutionarily conserved process in migrating cells. So it clearly has an important purpose to the cell." A network of proteins called the ...

Premature births may be linked to seasonal levels of pesticides and nitrates in surface water

...demy of Pediatrics. Dr. Winchester and colleagues found that preterm birth rates peaked when pesticides and nitrates measurements in surface water were highest (April-July) and were lowest when nitrates and pesticides were lowest (Aug.-Sept.). More than 27 million U.S. live births were studied from ...

Scientists: As rainfall changes, tropical plants may acclimate

Since these two species diverged most recently from human ancestors (about 5 and 14 million years ago respectively), this finding demonstrates that type II is a human-specific form that originated relatively recently, less th...
