Hundreds of published studies on natural selection may have drawn incorrect conclusions

Scientists at Penn State and the National Institute of Genetics in Japan have demonstrated that several statistical methods commonly used by biologists to detect natural selection at the molecular level tend to produce incorrect results.

Eye cells believed to be retinal stem cells are misidentified

Cells isolated from the eye that many scientists believed were retinal stem cells are, in fact, normal adult cells, investigators at St. Jude Children's Research Hospital have found.

Environment plays role in hypoplastic left heart syndrome

A congenital heart disease that often leads to death in newborns is significantly more common during the summer, leading researchers to believe that the environment, and not just genes that affect the heart, may play a role in causing "mini-epidemics" of this disease.

New cancer genomics web-based tools provide researchers a powerful new to visualize and analyze data

A Cancer Genomics Browser developed by researchers at the University of California, Santa Cruz, provides a new way to visualize and analyze data from studies aimed at improving cancer treatment by unraveling the complex genetic roots of the disease.

Gene scan shows body's sleep cycle influences numerous physical functions

The pineal gland - integral to setting the body's sleep and wake cycles - may be involved in a broad range of bodily functions, according to a study by researchers at the National Institutes of Health and other institutions.

Gene linked to lupus might explain gender difference in disease risk

In an international human genetic study, researchers at UT Southwestern Medical Center have identified a gene linked to the autoimmune disease lupus, and its location on the X chromosome might help explain why females are 10 times more susceptible to the disease than males.

DNA-based assembly line for precision nano-cluster construction

Building on the idea of using DNA to link up nanoparticles - particles measuring mere billionths of a meter - scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have designed a molecular assembly line for predictable, high-precision nano-construction.

New way to make stem cells avoids risk of cancer

A team of scientists has advanced stem cell research by finding a way to endow human skin cells with embryonic stem cell-like properties without inserting potentially problematic new genes into their DNA.

Nanoparticles in cosmetics may be harmful to the environment

Using aquatic microbes as their "canary-in-a-cage," scientists from Ohio have reported that nanoparticles now being added to cosmetics, sunscreens, and hundreds of other personal care products may be harmful to the environment.

Genetic variations may determine lung function and susceptibility to maternal smoking

A tiny variation within a single gene can determine not only how quickly and well lungs grow and function in children and adolescents, but how susceptible those children will be to exposure to second-hand tobacco smoke, even in utero, according to researchers from the University of Southern California.

Nanoparticles deliver gene therapy, killing tumors

Given that cancer is ultimately a genetic disease, it has long been the hope of researchers to use gene therapy to attack tumors where they might be most susceptible.

New approach to prostate cancer detection - Sarcosine may distinguish between slow-growing and aggressive prostate cancers

On Friday 20 March, US researcher Dr. Chris Beecher from the University of Michigan gave a well attended lecture about sarcosine, an N-methyl derivative of the amino acid glycine, at the 24th Annual EAU Congress in Stockholm, Sweden.
