Researchers isolate new risk marker for overweight children
...roctor said. "This study adds to a growing body of evidence we've collected that indicates measuring apoB48 levels as a means to measure chylomicron levels may be an important piece to the puzzle in understanding just who is and who isn't at risk of CVD." Proctor believes testing for apoB48 may become more ...Electric fish conduct electric duets in aquatic courtship

"Our study provides strong evidence that the 'rasp' [a certain electric signal] is a male advertisement call during courtship in this species," said Wong, noting that the males also serenade females with lower frequency "creaks."

...rous tissues, so MRS might provide more convincing evidence for the presence of disease. Yet, as with imaging, human interpretations of the findings can be ambiguous, so the researchers are applying CAD to increase the accuracy of interpretation here, as well.

"This new study provides evidence that chronic methylphenidate treatment begun in adolescence affects the brain's dopamine D2 receptor levels, and thus the brain's reward circuitry, differently depending on the age and treatment duration," Thanos said.

Inflammation is also linked to obesity and type 2 diabetes. The presence of excessive fat activates the production ...Ancient Etruscans were immigrants from Anatolia, or what is now Turkey
... Turin, Italy, will say that there is overwhelming evidence that the Etruscans, whose brilliant civilisation flourished 3000 years ago in what is now Tuscany, were settlers from old Anatolia (now in southern Turkey). Etruscan culture was very advanced and quite different from other known Italian cultures that...Marine phytoplankton changes form to protect itself from different predators

Academy of Sciences, researchers report the first evidence that a common species of saltwater algae also known as phytoplankton can change form to protect itself against attack by predators that have very different feeding habits.

...e CSHL research posits that those who did not find evidence of EPCs in tumors were probably looking for them in later stages of tumor progression when EPCs are diluted by host endothelial cells. The new results show that EPCs are only present in the earliest stages of tumor progression, before the formation o...Louisiana Tech researchers help find new sub-atomic particle
