Prenatal Stress Keeps Infants, Toddlers up at Night, Study Says

...n-anxious counterparts, were about 40 percent more likely to have an 18-month-old who refused to go to bed, woke early, and kept crawling out of bed. The childs rocky relationship with sleep often persisted until he or she was 30 months old. A similar effect was found in children born to mothers who wer...

Carnegie Mellon scientists find key HIV protein makes cell membranes bend more easily

...ade, cell-like structures called liposomes. FP-23 likely plays several roles in viral fusion, according to the researchers. One role already suspected is that FP-23 attaches to its T cell victim to facilitate a change in the shape of gp41, which in turn drives uptake of HIV RNA and proteins by the T cell. ...

Such genome analyses of unprecedented details will allow a much better understanding of local adaptation, and this...

Common cancer gene sends death order to tiny killer

...articipates in p53's uncanny ability to kill cells likely to become malignant because of damaged genes in their nuclei. MicroRNAs are small chains of ribonucleic acid (RNA) made by the same machinery that produces other types of RNA in the cell, such as the messenger RNAs that carry the instructions to make...

Agent slows aging in mice

...n the final results of this study, other labs will likely try to repeat the results in animals. Much more research is needed before any possible human anti-aging drug could emerge, Miller says. “Even if this agent turns out to be good for mice, it won’t be possible to tell without careful studies of hum...

"This is significant for farmer costs because one application of agrichar may be the equivalent of compost applications of the same weight every year ...

Cigarette smoke alters DNA in sperm, genetic damage could pass to offspring

According to Yauk, previous studies have shown that Ms6-hm and similar locations of non-coding DNA are sensitive to damage from radiation, mutagenic chemicals and intense industrial air p...

Snoring in children might be an allergic type disease

Studies to find better ways to preserve human eggs, ovarian tissue under way

In fact, many in vitro fertilization programs, including the one she directs at MCG Health System, are moving toward vitrification, which also seems to work faster, better and cheaper in embryos. ...

The next step is to perform more detailed toxicity tests in animals, and then move toward human testing. The important lesson from the new study, the researchers wrote in their r...

Sun exposure early in life linked to specific skin cancer gene mutation

...n, found in about half of all melanomas, were more likely to report high levels of sun exposure before age 20. People with the NRAS mutation were more likely to have had high exposure between the ages of 50 and 60. About 15 percent of melanomas contain the N...
