Toxoplasmosis Infection? No Fear!
A new study has revealed how the parasite that causes toxoplasmosis colonizes the mouse brain in the form of cysts to such an extent that it drastically alters the mouse’s behavior.

Cannabis, Anxiety and Stress – What’s the Connection?
A molecule, 2-arachidonoylglycerol, also referred to as “2-AG”, protects against stress by reducing “anxiety-causing” connections between two particular regions in the brain – 2-AG elicits its effect by activating the same receptors as cannabis.

Electrical Stimulation Could Enhance PTSD Treatment by Improving Metamemory
Researchers have published research suggesting that transcranial electrical stimulation can enhance metamemory, which is the sensitivity of whether memories are accurately recalled. This finding, say the authors, could have implications for PTSD treatment.

Beauty Sleep Could Be Real, Say Body Clock Biologists
Biologists from The University of Manchester have explained for the first time why having a good night's sleep really could prepare us for the rigours of the day ahead.

Study of Over 170,000 Individuals Identifies Genes Associated With High Alcohol Consumption
A new research study utilized a GWAS approach to identify specific genetic variants associated with high levels of alcohol consumption. The sample consisted of UK Biobank participants and US GERA participants.
Cell death balances division, in both multicellular and unicellular organisms. Programmed cell death shapes embryonic development and serves a protective role by maintaining homeostasis of cell number, and removing infected and damaged cells. Here, we examine one common branch of cell death, apoptosis, and explain why studying aberrations in apoptotic signaling is important for understanding and addressing a range of human pathologies.
We recently spoke with Paul Brennan, President and CEO at NervGen Pharma, to gain his insights on why previous attempts to treat Alzheimer's disease have failed, how the novel technology platform NVG-291 works and what promise it holds for AD.
This is an image of a mini brain tumor (tumoroid) with blood vessels grown in the lab. Tumoroids can be used to study the interaction between brain tumor (glioblastoma) cells and blood vessel forming (endothelial) cells, potentially providing a platform for the development of personalized therapies.
