Identifying genes key to human memory: Insights from genetics and cognitive neuroscience

EurekAlert! Materials - Sat, 2017-03-25 21:00
(Cognitive Neuroscience Society) Researchers have identified more than 100 genes important for memory in people. The study, being presented at the CNS annual conference in San Francisco, is the first to identify correlations between gene data and brain activity during memory processing, providing a new window into human memory. It is part of the nascent but growing field of 'imaging genetics,' which aims to relate genetic variation to variation in brain anatomy and function.

An intriguing new gene candidate in the search for Alzheimer disease therapies

EurekAlert! Biology - Thu, 2017-03-23 21:00
(Brigham and Women's Hospital) Tau pathology is one of the defining features of Alzheimer disease (AD), which is the most common form of dementia in older age. While symptomatic treatments exist, there are currently no preventive therapies for AD. Investigators at BWH and Rush University Medical Center reported the discovery of a new gene that is associated with Tau accumulation. Published in Molecular Psychiatry, the paper describes the identification and validation of a genetic variant within the protein tyrosine phosphatase receptor-type delta (PTPRD) gene.

Biodiversity loss shifts flowering phenology at same magnitude as global warming

EurekAlert! Biology - Thu, 2017-03-23 21:00
(Columbia University) Researchers have revealed that declining plant diversity -- from habitat loss, human use, and other environmental pressures -- causes plants to flower earlier, and that the effects of diversity loss on the timing of flowering are similar in magnitude to the effects of global warming. The finding could have a powerful influence on the way scientists study ecosystem changes and measure the effects of global warming.

Study confirms prescription weight-loss medication helps with opiate addiction recovery

EurekAlert! Materials - Thu, 2017-03-23 21:00
(University of Texas Medical Branch at Galveston) Researchers from the University of Texas Medical Branch at Galveston have confirmed that a prescription weight-loss pill decreases the urge to use opiates such as oxycodone. In a study published in ACS Chemical Neuroscience, the researchers led by UTMB scientist Kathryn Cunningham found that the drug, lorcaserin, reduced the use and craving for the opioid oxycodone in preclinical studies.

In a quantum race everyone is both a winner and a loser

EurekAlert! Materials - Thu, 2017-03-23 21:00
(University of Vienna) Our understanding of the world is mostly built on basic perceptions, such as that events follow each other in a well-defined order. Such definite orders are required in the macroscopic world, for which the laws of classical physics apply. The current work by a team of physicists from the University of Vienna is the first experimental quantification of such a superposition. It will be published in an upcoming issue of Science Advances.

(Washington University in St. Louis) Star-shaped cells called astrocytes, long considered boring, 'support cells,' are finally coming into their own. To everyone's surprise they even play an important role in the body's master clock, which schedules everything from the release of hormones to the onset of sleepiness.
