"In particular, issues needing more attention include the content and labeling of vitamin and mineral supplements and the effects of these products on nutrient adequacy as well as in chronic degenerative disease prevention. In this quest, the development of more and better surrogate markers of a...

Individual differences in a clock gene predict decline of performance during sleep deprivation

...ant of the gene performed very poorly on tests for attention and working memory. The authors point out that this early-morning period corresponds to stretches of time when shift workers struggle to stay awake, during which many accidents related to sleepiness occur. But the scientists also emphasize that th...

NT researchers discover breakthrough in malaria treatment

...ting humans, P. vivax and P. falciparum. Although attention focuses on the more virulent P. falciparum, vivax malaria causes a huge amount of illness in the tropical countries of our region and puts many Australian travelers at risk of disease. Vivax malaria is becoming increasingly resistant to standard tr...

Hybrid molecule causes cancer cells to self-destruct

...r a long time, cancer researchers did not pay much attention to the use of sugars in fighting cancer," said Gopalan Sampathkumar, a postdoctoral fellow in the university's Department of Biomedical Engineering and lead author of the journal article. "But we found that when the right sugar is matched with the ri...

Lithium builds gray matter in bipolar brains, UCLA study shows

...s 15 percent higher in areas that are critical for attention and controlling emotions. The neurobiological underpinnings of bipolar disorder ?an illness marked by a roller coaster of emotions between mania and depression ?are not well understood. Nor is it understood how lithium works in controlling these s...

UTSA researchers examine effects of global warming on Antarctic

... Earth and Environmental Science are turning their attention to the South Pole to find out if global warming is having similar effects in the frigid Antarctic region. UTSA Earth and Environmental Science Assistant Professor Hongjie Xie and doctoral student Burcu Cicek are analyzing data collected in Decembe...

Research finds music training 'tunes' human auditory system

...ferently pitched "mi" sounds. "Even with their attention focused on the movie and though the sounds had no linguistic or musical meaning for them, we found our musically trained subjects were far better at tracking the three different tones than the non-musicians," says Wong, director of Northwestern’s Spe...

Bringing this information to the physician’s attention is important because the doctor may be focused on the patient’s physical complaints and unless prompted by the patient or test results is unlikely to assess the patient’s mental status. "Doctors like to quantify things. We can objectively measure...

Wired for sound: How the brain senses visual illusions
