Here is what I am reading today:
“The discovery, published today in The Journal of Neuroscience, could lead to new information about how the gut signals to our brains about when we’re full, and when to keep eating.
In the University’s Nerve-Gut Research Laboratory, Dr Stephen Kentish investigated how the nerves in the stomach respond to stretch, which occurs as a consequence of food intake, at three-hourly intervals across one day.”
“”To the best of our knowledge, this is the first paper that shows rapid alterations in gene expression within subjects associated with mindfulness meditation practice,” says study author Richard J. Davidson, founder of the Center for Investigating Healthy Minds and the William James and Vilas Professor of Psychology and Psychiatry at the University of Wisconsin-Madison.
“Most interestingly, the changes were observed in genes that are the current targets of anti-inflammatory and analgesic drugs,” says Perla Kaliman, first author of the article and a researcher at the Institute of Biomedical Research of Barcelona, Spain (IIBB-CSIC-IDIBAPS), where the molecular analyses were conducted.”
“A group of 2,000 dead mice equipped with cardboard parachutes have been airdropped over a United States Air Force base in Guam in order to poison brown tree snakes.
It may sound like the plot to an animated movie starring the vocal talents of Gilbert Godfried, but we assure you this is actually happening.”
“Dr. Gobbi and her colleagues compared the social behaviour and brain anatomy of mice that had been raised with both parents to those that had been raised only by their mothers. Mice raised without a father had abnormal social interactions and were more aggressive than counterparts raised with both parents. These effects were stronger for female offspring than for their brothers. Females raised without fathers also had a greater sensitivity to the stimulant drug, amphetamine.”
“”Discovering that the hypothalamus can rapidly produce large amounts of estradiol and participate in control of gonadotropin-releasing hormone neurons surprised us,” says Ei Terasawa, professor of pediatrics at the UW School of Medicine and Public Health and senior scientist at the Wisconsin National Primate Research Center. “These findings not only shift the concept of how reproductive function and behavior is regulated but have real implications for understanding and treating a number of diseases and disorders.”"
“For 4 years, paleogeneticist Svante Pääbo has been chasing a ghost species of ancient human. Known only by its DNA and three scrappy fossils from Denisova Cave in Siberia, this extinct lineage has left genetic traces in living Southeast Asians, so Pääbo expected to find its DNA in bones from across Asia. He had come up empty. Now, his team at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, has finally found part of the broken Denisovan trail—not in some mysterious Asian fossil, but in a proto-Neandertal from Spain.”
