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

Jan 16 2018 - 00:01
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

Jan 16 2018 - 00:01
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

Jan 16 2018 - 00:01
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.

Redshift space distortions measured by quasars in scientific first

Jan 16 2018 - 00:01
The eBOSS team released its latest results on Jan. 10, 2018: a measurement of redshift space distortions (RSD) with high significance has been successfully accomplished using observations of quasars distributed 6.8 to 10.5 billion light years away from Earth (with redshifts 0.8 to 2.2). This is the first probe of cosmic structure growth using quasars.

Key player in cell metabolism identified

Jan 16 2018 - 00:01
Published in Nature Cell Biology (NCB), the study shows that the EXD2 protein is critical for the mitochondria, the cell's powerhouses, to produce energy. This protein was previously thought to be located in the cell nucleus and to be involved in DNA repair. The results contribute to our basic understanding of mitochondria and suggest that EXD2 could be important for fertility and represent a potential target for cancer therapy.
