Concussion from hits to the side of the head
Concussion from hits to the side of the head
Through a combination of biometric tracking, simulated modeling and medical imaging, researchers detail how hits to the side of the head cause concussion. Concussion researchers have long suggested that damage to the corpus callosum, a thick bundle of nerves that connects the brain's two halves, could result in some common side effects of concussion, like dizziness or vision problems.

Protection from Zika virus may lie in a protein derived from mosquitoes
By targeting a protein found in the saliva of mosquitoes that transmit Zika virus, Yale investigators reduced Zika infection in mice. The finding demonstrates how researchers might develop a vaccine against Zika and similar mosquito-borne viruses, the study authors said. There is no current vaccine or therapy for Zika virus infection, which caused substantial illness, including birth defects, during the 2015 outbreak that impacted over a million people in the Americas.

Vitamin B3 analogue boosts production of blood cells
Scientists from EPFL and the UNIL/Ludwig Cancer Research have found that supplementing diet with nicotinamide riboside, an analogue of vitamin B3, boosts the production of blood cells by improving the function of their stem cells. This can help overcome problems in stem cell-based therapies that treat leukemia and aggressive lymphomas.  Stem cell-based therapies are becoming more and more common, especially in the treatment of blood cancers like lymphoma and leukemia.

Brain region plays key role in regulation of parenting behavior
FINDINGS The amygdala — a region of the brain known to be involved in emotions and social behaviors — has been found to play a critical role in the regulation of parenting behavior, according to a new study by UCLA researchers. Differences in this brain region between males and females help to explain why the two sexes behave differently as parents.

Pesticides found to affect bees' genes
Pesticides found to affect bees’ genes
The activity of dozens of genes are changed in bees exposed to pesticides, providing clues as to how these chemicals affect bee brains in the wild. The finding could provide clues as to why certain pesticides have been linked to bee colony declines. Our work reveals that neurotoxic pesticides not only directly target the cells of the nervous system, but also indirectly affect the normal activity of the exposed organism's genes.
