Gene linked to lupus might explain why females are 10 times more susceptible to the disease

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

Discovery of new cancer gene

Researchers have identified a new cancer gene - one that is common to many cancers and affects the most basic regulation of our genes.

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.

Evolutionary origin of bacterial chromosomes revealed

Researchers have unveiled the evolutionary origin of the different chromosomal architectures found in three species of Agrobacterium.

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.

Ovarian cancers detected early may be less aggressive, questioning effectiveness of screening

The biology of ovarian cancers discovered at an early stage may render them slower growing and less likely to spread than more aggressive cancers, which typically are discovered in an advanced stage, according to a study led by investigators in the Duke Comprehensive Cancer Center.
