- Level of oxytocin in pregnant women predicts mother-child bond
10-15-2007 · EurekAlert!
In animals, oxytocin, dubbed 'the hormone of love and bonding,' is critically important for the development of parenting, is elicited during sexual intercourse, and is involved in maintaining close relationships. These findings implicate oxytocin in the bonding process, but little research has been done on this relationship in humans. Ruth Feldman conducted the first study to demonstrate the links between oxytocin and bonding in human mothers.

- Ancient retroviruses spurred evolution of gene regulatory networks in humans and other primates
11-13-2007 · EurekAlert!
Ancient retroviruses -- distant relatives of the human immunodeficiency virus -- helped a gene called p53 become an important "master gene regulator" in primates, according to a new study.

- New lab mice pave way for novel studies of human infections
10-23-2006 · UT Southwestern Medical Center
A new type of laboratory mouse developed at UT Southwestern Medical Center can fight certain infections the same way humans do, making the rodents very useful for novel studies of human-pathogen interaction and developing disease therapies.

- Unraveling where chimp and human brains diverge
11-13-2006 · EurekAlert!
Six million years ago, chimpanzees and humans diverged from a common ancestor and evolved into unique species. Now UCLA scientists have identified a new way to pinpoint the genes that separate us from our closest living relative -- and make us uniquely human.

- New finding points way to foiling anthrax's tricks
11-30-2006 · EurekAlert!
Anthrax, when inhaled, is nearly always fatal, in part because the bacteria have a very effective way of stealing iron from human cells to reproduce. This involves two molecules, siderophores, that compete with the body's own iron-transport molecules. UC Berkeley researchers have now found that humans produce a protein that sidelines one of these siderophores, but not the other. A drug that blocks the second siderophore should be able to stop anthrax in its tracks.

- Using brain scans, researchers find evidence for a 2-stage model of human perceptual learning
03-14-2007 · EurekAlert!
Using advanced brain imaging techniques, researchers at Georgetown University Medical Center have watched how humans use both lower and higher brain processes to learn novel tasks, an advance they say may help speed up the teaching of new skills as well as offer strategies to retrain people with perceptual deficits due to autism.

- Common virus may contribute to obesity in some people, new study shows
08-20-2007 · EurekAlert!
A common virus may cause obesity in some people, according to new evidence in a controlled laboratory study. Scientists showed that infection with human adenovirus-36, long recognized as a cause of respiratory and eye infections in humans, transforms adult stem cells obtained from fat tissue into fat cells. The study, which might lead to new treatments for obesity, will be reported in August at the American Chemical Society national meeting in Boston.

- Researchers studying how singing bats communicate
10-18-2007 · EurekAlert!
Bats are the most vocal mammals other than humans, and understanding how they communicate during their nocturnal outings could lead to better treatments for human speech disorders, say researchers at Texas A&M University.

- Reprogrammed human adult stem cells rescue diseased muscle in mice
12-12-2007 · EurekAlert!
Scientists report that adult stem cells isolated from humans with muscular dystrophy can be genetically corrected and used to induce functional improvement when transplanted into a mouse model of the disease. The research, published by Cell Press in the December issue of Cell Stem Cell, represents a significant advance toward the future development of a gene therapy that uses a patient's own cells to treat this devastating muscle-wasting disease.
