Genes for 9 health indicators
...reviously unknown loci. Five of these associations - HDL with NR1H3 (LXRA), LDL with AR and FADS1/FADS2, glucose with MTNR1B, and insulin with PANK1 - implicate
genes with known or postulated roles in metabolism, and are good candidates for further study of the biological role they might play in these conditio...
Yale researchers unravel mystery of brain aneurysms

New study points to agriculture in frog sexual abnormalities
...hese two areas of human disturbance, do we see a greater proportion of abnormal animals in one versus another?" Guillette said.
Because the results implicate
agriculture, future research can narrow the focus to agricultural chemicals, McCoy said.
"Because we know what chemicals are used at these agricult...
UC Davis researchers discover how HIV turns food-poisoning into lethal infection

a mechanism by which HIV evades the powerful drugs used to treat AIDS.
We have found the defect in the immune response that allows Salmonella to cr...
How mammals fuel milk production may have implications for cancer

The fMRI results also revealed that non-...
How blood flow dictates gene expression
..., they had an abnormally high cardiac output, as measured by ultrasound, while the overall structure of their blood vessels was normal. These findings implicate

Now that Klf2 has been established as an important regulator of blood flow in l...
Carnegie Mellon researchers discover key deficiencies in brains of people with autism
