A new study from Utrecht and Cambridge Universities has for the first time found that an administration of testosterone under the tongue in volunteers negatively affects a person’s ability to ‘mind read’, an indication of empathy. The findings are …
ITHACA, N.Y. — It’s an incendiary topic in academia — the pervasive belief that women are underrepresented in science, math and engineering fields because they face sex discrimination in the interviewing, hiring, and grant and manuscript review …
When a laboratory rat learns how to reach for and grab a food pellet — a pretty complex and unnatural act for a rodent — the acquired knowledge significantly alters the structure of the specific brain cells involved, which sprout a whopping …
Charles Darwin based his groundbreaking theory of natural selection on the realization that genetic variation among organisms is the key to evolution.
Some individuals are better adapted to a given environment than others, making them more l…
HOUSTON, Jan. 10, 2011 — Research with significant implications in the treatment and intervention of cancer and obesity has been published recently in two prestigious journals by University of Houston (UH) biochemist Dr. Jan-Åke Gustafsson….
PROVIDENCE, R.I. [Brown University] — A pipefitter knows how to make an exact cut on a metal rod. But it’s far harder to imagine getting a precise cut on a carbon nanotube, with a diameter 1/50,000th the thickness of a human hair.
In a pape…
From atomic crystals to spiral galaxies, self-assembly is ubiquitous in nature. In biological processes, self-assembly at the molecular level is particularly prevalent.
Phospholipids, for example, will self-assemble into a bilayer to form a cell…
HOUSTON, Nov. 19, 2010 — University of Houston (UH) physicists are using complex computer simulations to illuminate the workings of a crucial protein that, when malfunctioning, may cause Alzheimer’s and cancer.

COLUMBIA, Mo. — In modern culture, it is not considered socially acceptable for married people to have extramarital sexual partners. However, in some Amazonian cultures, extramarital sexual affairs were common, and people believed that when a woma…
A new species of dinosaur discovered in Arizona suggests dinosaurs did not spread throughout the world by overpowering other species, but by taking advantage of a natural catastrophe that wiped out their competitors.
The new dinosaur, named Sarahs…
Scientists at the University of Oregon have determined the fine-scale genetic structure of the first animal to show an evolutionary response to rapid climate change.
They used a high-throughput sequencing technique called Restriction-site As…
Genes reside along long chains of DNA called chromosomes. UCLA researchers have found that a variation in a gene on the sex chromosome X may enhance an immune response that leads to lupus in men.
Systemic lupus erythematosus (SLE) is an a…
