Scientists examine eons-old water for microorganisms

Researchers from the University of Delaware and the University of California at Riverside have thawed ice estimated to be at least a million years old from above Lake Vostok, an ancient lake that lies hidden more than two miles beneath the frozen surface of Antarctica.

New disease model for Huntington's

Huntington's disease is a genetic time bomb: Programmed in the genes, it appears at a predictable age in adulthood, causing a progressive decline in mental and neurological function and finally death.

Ozone response greater with increasing BMI

A new study provides the first evidence that people with higher body mass index (BMI) may have a greater response to ozone than leaner people.

Study of Mexican Americans shows that polymorphisms of the CYP2E1 gene enhance susceptibility to alcoholism

Mexican Americans make up 66 percent of the U.S. Hispanic population and, when compared to other ethnic groups, show high rates of heavy drinking and alcohol-related problems.

New genetic evidence supports theory migration from Siberia gave rise to native peoples of North and South America

Did a relatively small number of people from Siberia who trekked across a Bering Strait land bridge some 12,000 years ago give rise to the native peoples of North and South America?

Flip-flopping gene expression can be advantageous

One gene for pea pod color generates green pods while a variant of that gene gives rise to the yellow-pod phenotype, a feature that helped Gregor Mendel, the 19th century Austrian priest and scientist, first describe genetic inheritance.

Problematic drinking and alcohol dependence linked to high number of sex partners

Previous studies have linked heavy drinking and conduct disorder to high-risk sexual behaviors that can, in turn, lead to unintended pregnancies, infection, and damage to reproductive health.

Non-Caucasians at higher risk for severe metastatic breast cancer pain

A new study finds significant racial differences in the risk of pain related to metastatic breast cancer.

The missing grey cells that turn people into obsessives

Scientists in the UK have discovered new evidence as to why obsessive compulsive disorder (OCD) runs in families.

Vitamin E can significantly reduce risk of heart attacks for diabetics with certain gene variant

Vitamin E supplements can significantly reduce the risk of heart attacks and related deaths for diabetics who carry a particular version of a gene, according to researchers at the Technion-Israel Institute of Technology and the Clalit Health Services in Israel.

Scientists identify key nerve navigation pathway

Newly launched nerve cells in a growing embryo must chart their course to distant destinations, and many of the means they use to navigate have yet to surface.

Pregnant women pass on the effects of smoking

Smoking during pregnancy has many adverse effects on fetal development.

Human pluripotent stem cells without human cloning

Two major scientific papers published this week in Science and Cell unveil a proven way to generate patient-matched human pluripotent stem cells without human cloning, and without the use of human embryos or human or animal eggs.

Human skin could be a new source of stem cells

A simple recipe—including just four ingredients—can transform adult human skin cells into cells that resemble embryonic stem cells, researchers report in an immediate early publication of the journal Cell, a publication of Cell Press.

Whole-body positron emission tomography can reassure cervical cancer patients

Whole-body PET (positron emission tomography) scans done three months after completion of cervical cancer therapy can ensure that patients are disease-free or warn that further interventions are needed, according to a study at Washington University School of Medicine in St. Louis.

Monkeys fend off AIDS-like symptoms with enhanced HIV vaccine

Researchers at the University of Pennsylvania School of Medicine have discovered that using an immune system gene to enhance a vaccine used to study HIV in macaque monkeys provides the animals with greater protection against simian HIV (SHIV) than an unmodified vaccine.

Discovery of 300 previously unidentified human genes

Using supercomputers to compare portions of the human genome with those of other mammals, researchers at Cornell have discovered some 300 previously unidentified human genes, and found extensions of several hundred genes already known.

The science of cancer health disparities in racial/ethnic minorities and the medically underserved

The latest biological, clinical and social research behind how cancer affects different racial and ethnic groups will be the focus of the first American Association for Cancer Research conference on the topic, entitled "The Science of Cancer Health Disparities in Racial/Ethnic Minorities and the Medically Underserved."

Bortezomib pushes cancer cells into overdrive, so that they self-destruct

University of Michigan Comprehensive Cancer Center researchers have discovered that bortezomib, a promising cancer drug, is able to strike a blow against melanoma tumor cells by revving up the action of a cancer-promoting gene.
