From the energetic border collie to the friendly golden retriever, more than 350 dog breeds exist today, each with specific physical and behavioral traits. Although previous research on dog genomes has revealed the genetic basis of variations in body size and shape among breeds, the genetic underpinning of complex behaviors—hunting, herding, guarding, pointing, drafting, and more—has been a tough challenge to crack. Now researchers at the National Human Genome Research Institute (NHGRI) have discovered that the ancestry…

Severe COVID-19 is linked to changes in the brain that mirror those seen in old age, according to an analysis of dozens of post-mortem brain samples. The analysis revealed brain changes in gene activity that were more extensive in people who had severe SARS-CoV-2 infections than in uninfected people who had been in an intensive care unit (ICU) or had been put on ventilators to assist their breathing—treatments used in many people with serious COVID-19. The study, published on 5 December in Nature Aging, joins a bevy of…

Brendan Fraser may have been the epitome of human perfection back in 1997 when he was filming the Disney spoof George of the Jungle. Fraser’s wild man of the jungle build was every bit as spectacular as Disney’s animated Tarzan, right down to his six-pack abs. But. according to Fraser, the physical regimen required for the part made him almost as light-headed as George was after crashing into that tree. https://www.youtube.com/watch?v=ITlM041DW1U Fraser recently caught up with his former Airheads co-star Adam Sandler…

The child was suffering from anti-NMDAR (N-methyl-D-aspartate receptor) encephalitis, a rare and difficult-to-diagnose malfunction of the brain. Blood plasma exchanges helped a 5-year-old with a rare autoimmune disorder get better.The sick child’s prognosis, who had not responded to conventional treatment, was bleak. Nevertheless, a group of doctors from Rutgers University thought there could be hope despite the conventional wisdom against pursuing any further treatment.What transpired over the following several weeks in…

The research reveals that synaptotagmin-3 plays a role in high-frequency synaptic transmission.Researchers at Oregon Health & Science University have discovered a key molecule that contributes to understanding and treating neurological diseases like epilepsy and autism.Researchers at Oregon Health & Science University have discovered a long-sought gene-encoded protein that allows the brain to communicate a number of signals across synapses, or gaps between neurons.The discovery was recently published in the…

Tiny antenna-like organelles once thought to be holdovers from our ancient past appear to play a crucial role in keeping track of time, according to a recent study on mice by researchers from the University of California, Irvine (UCI), in the US.Known as cilia, the microtubule projections can be found throughout the more complex branches of the tree of life, including on many of our own cells.Where they often have a role in motion, either pushing cells around or moving materials close to their surface, most in the human…
