International study identify the process of rock formed by meteors or nuclear blasts

Eurekalert - 14 hours 9 min ago
Scientists from Brazil, China and Italy have reached a model to map out the phases in which silica (SiO2) transforms into coesite rock, by analyzing how the inelastic scattering of light among molecules changes according to pressure variation. Computer simulation was required in the study of coesite, found on a crater produced by a comet or asteroid that hit Mexico and led to extinction of the dinosaurs.

Obesity and overweight multiply the risk of suffering cancer and heart disease

Eurekalert - 14 hours 9 min ago
Obese women are 12 times more like to get cancer than those of a normal weight. Obese men are twice as likely to develop this disease. The data is the result of the largest Spanish study ever in this field, involving a 10-year follow up of 54,000 people from 7 autonomic communities. Only 26 percent of those taking part had a normal weight. The rest were either obese or overweight.

Evening hours may pose higher risk for overeating, especially when under stress, study finds

Eurekalert - 14 hours 9 min ago
Experiments with a small group of overweight men and women have added to evidence that 'hunger hormone' levels rise and 'satiety (or fullness) hormone' levels decrease in the evening. The findings also suggest that stress may increase hunger hormone levels more in the evening, and the impact of hormones on appetite may be greater for people prone to binge eating.

Cannabis abuse alters activity of brain regions linked to negative emotion

Eurekalert - 14 hours 9 min ago
Young people with cannabis dependence have altered brain function that may be the source of emotional disturbances and increased psychosis risk that are associated with cannabis abuse, according to a new study published in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging. The alterations were most pronounced in people who started using cannabis at a young age. Findings reveal potential negative long-term effects of heavy cannabis use on brain function and behavior.

Miles Davis is not Mozart: The brains of jazz and classical pianists work differently

Eurekalert - 14 hours 9 min ago
A musician's brain is different to that of a non-musician. Making music requires an interplay of abilities which are also reflected in more developed brain structures. Scientists at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig have discovered that these capabilities are embedded in a much more finely tuned way than assumed: The brain activity of jazz pianists differs from those of classical pianists, even when playing the same piece of music.
