A massive genome-wide analysis of approximately 200,000 military veterans has identified six genetic variants linked to anxiety, researchers from Yale and colleagues at other institutions report Jan. 7 in the American Journal of Psychiatry.
Some of the...
The peaceful and delicate co-existence of friendly gut bacteria and the immune system relies on highly coordinated information exchange between immune system cells and certain cells lining the intestine. Until now, scientists generally believed these two...
Fat cells are filled with droplets coated by molecules that act like hotel doormen: These “doormen” control cellular access for nutrients as well as for the exit of energy-supplying molecules called lipids. In healthy individuals, outgoing and incoming...
The brain is a sort of fortress, equipped with barriers designed to keep out dangerous pathogens. But protection comes at a cost: These barriers interfere with the immune system when faced with dire threats such as glioblastoma, a deadly brain tumor for...
People who had recently used psychedelics such as psilocybin report a sustained improvement in mood and feeling closer to others after the high has worn off, shows a new Yale study published the week of Jan. 20 in the journal Proceedings of the National...
The type of salamander called axolotl, with its frilly gills and widely spaced eyes, looks like an alien and has other-worldly powers of regeneration. Lose a limb, part of the heart or even a large portion of its brain? No problem: They grow back.
“It...
Previous estimates of preventable deaths of hospitalized patients may be two to four times too high, a new Yale School of Medicine study suggests.
The meta-analysis of eight studies of inpatient deaths, published in the Journal of General Internal...
Glioblastomas are relentless, hard-to-treat, and often lethal brain tumors. Yale scientists have enlisted a most unlikely ally in efforts to treat this form of cancer — elements of the Ebola virus.
“The irony is that one of the world’s deadliest viruses...
Merely a brief introduction to mindfulness helps people deal with physical pain and negative emotions, a new study by researchers at Yale, Columbia, and Dartmouth shows.
The effect of mindfulness was so pronounced, they found, that even when participants...
A massive analysis of the entire genomes of 2,658 people with 39 different types of cancer has identified mutations in 179 genes and gene regulators as “drivers” — variations in DNA sequences that lead to the development of cancer.
The work is part of the...
