Night, weekend delivery OK for babies with birth defects

Posted: 10 Feb 2012 10:33 AM PST

Weekday delivery is no better than night/weekend delivery for infants with birth defects, according to a new study. Researchers found that infants with birth defects that were delivered at night or over the weekend fared just as well as those delivered on a weekday -- they stayed at the hospital for the same amount of time, were admitted to the NICU at the same rate, and were given antibiotics or got help breathing just as often.

Protein libraries in a snap

One undergraduate student will depart university with not only a degree but also a possible patent for his invention of an efficient way to create protein libraries, an important component of biomolecular research.

Cochlear implants may be safe, effective for organ transplant patients

Cochlear implants may be a safe, effective option for some organ transplant patients who've lost their hearing as an unfortunate consequence of their transplant-related drug regime, researchers report.

New research finds that 16- to 18-year-olds perform better academically when they shave about two hours off what current guidelines prescribe.

Unpicking HIV's 'invisibility cloak'

Posted: 10 Feb 2012 07:47 AM PST

Drug researchers hunting for alternative ways to treat human immunodeficiency virus (HIV) infections may soon have a novel target -- its camouflage coat. HIV hides inside a cloak unusually rich in a sugar called mannose, which it uses to slip past the immune system before infecting its host's cells. Recently, however, biochemists discovered a family of chemical compounds that stick strongly to mannose. Understanding how this mechanism works could reveal a way to make drugs adhere to and kill HIV.

Tell me how you are, and I know how long you will live

The way people rate their health determines their probability of survival in the following decades. Researchers have demonstrated that for ratings ranging from "excellent," "good," "fair," and "poor" to "very poor," the risk of mortality increases steadily – independently of such known risk factors as smoking, low education levels or pre-existing diseases.

Drug quickly reverses Alzheimer's symptoms in mice

Posted: 09 Feb 2012 11:40 AM PST

Neuroscientists have made a dramatic breakthrough in their efforts to find a cure for Alzheimer's disease. The use of a drug appears to quickly reverse the pathological, cognitive and memory deficits caused by the onset of Alzheimer's in mice.

New prenatal genetic test is much more powerful at detecting fetal abnormalities

Posted: 09 Feb 2012 11:39 AM PST

A national, U.S. federally funded study has found that testing a developing fetus' DNA through chromosomal microarray (CMA) provides more information about potential disorders than does the standard method of prenatal testing, which is to visually examine the chromosomes (karyotyping).

Barriers to the use of fingerprint evidence in court is unlocked by statistical model

Posted: 09 Feb 2012 07:20 AM PST

Fingerprints that are potential key pieces of evidence in court currently are not being considered due to shortcomings in the way this evidence is reported. Now, a statistical model has been developed that enables the weight of fingerprint evidence to be expressed in quantitative terms, paving the way for its full inclusion in the process of identifying criminals, according to a new report.
