Ancient African exodus mostly involved men

Modern humans left Africa over 60,000 years ago in a migration that many believe was responsible for nearly all of the human population that exist outside Africa today.

Researchers identify gene linked to inherited form of fatal lung disease

Researchers at UT Southwestern Medical Center have determined that a mutation in a gene known for its role in defending the lungs against invading pathogens is responsible for some inherited cases of a lethal lung disease affecting older adults. The same mutation may also be associated with lung cancer, the researchers said.

Borderline personality disorder more common than schizophrenia

According to the National Institute of Mental Health, borderline personality disorder (BPD) is more common than schizophrenia or bipolar disorder and is estimated to affect 2 percent of the population.

Breast cancer genome shows instability of cancer

A newly published genome sequence of a breast cancer cell line reveals a heavily rearranged genetic blueprint involving breaks and fusions of genes and a broken DNA repair machinery, said researchers at Baylor College of Medicine in a report that appears online in the journal Genome Research.

Fatherhood gene determines if it's a boy or a girl

According to recent research whether men are likely to father a boy or a girl is determined by a "fatherhood gene".

New research moves us one step closer to personalised breast cancer treatment

Cancer Research UK scientists have found that a test, already used in breast cancer diagnosis, can also predict who will and who won't benefit from commonly used chemotherapy drugs.

New understanding of mechanism that regulates DNA methylation

Researchers in a University of Oregon lab have shed more light on the mechanism that regulates DNA methylation, a fundamental biological process in which a methyl group is attached to DNA, the genetic material in cells of living organisms.

Discovery of seven new sites in the human genome found to influence obesity

In one of the largest studies of its kind, a multinational team led by scientists from deCODE genetics has reported the discovery of common variations at seven new sites in the human genome found to influence obesity.

Promising clinical trial for Progeria "premature aging" disease

One of the fastest translations of a basic research discovery into a promising clinical trial for an "untreatable" and fatal disorder will be discussed publicly for the first time by the key players in this remarkable research story, on Sunday, Dec. 14, at the American Society for Cell Biology (ASCB)'s annual meeting in San Francisco.

Good news for young male cancer patients

"Young men undergoing treatment for cancer often want to know how the disease and its treatment affect their chances of fathering healthy children. Our large-scale study shows that there is a slightly higher risk of deformities, but the actual risk of having a child with deformities is nevertheless extremely low. I think this is good news!"

Researchers identify how key mutations occur in human lymphomas

Researchers at the Keck School of Medicine of the University of Southern California (USC) have explained how certain key mutations occur in human lymphomas - a process that has, until now, remained a mystery.

Biologist provides new theory on mechanisms that control molecular motors

Biologists have known for decades that cells use tiny molecular motors to move chromosomes, mitochondria, and many other organelles within the cell, but no one has been able to understand what "steers" these engines to their destinations.

New cause of atrial fibrillation found

A new study shows that atrial fibrillation--the most common form of sustained heart arrhythmia--can be caused in an unexpected way.

Enzyme that mutates antibodies also targets cancer-causing gene

The human immune system is in a perpetual state of self-experimentation. It expertly mutates and shuffles the DNA of its own cells to evolve new defenses against the vast array of microbes that try to invade our bodies.

Researchers capture never before seen undulations of "dancing chromosomes"

The rhythm of life may beat far deeper than anyone previously thought. And it may gyrate and pulse in a way that rivals the sensuous choreography of "Dirty Dancing."

Men inherit tendency to have more sons or more daughters from their parents

A Newcastle University study involving thousands of families is helping prospective parents work out whether they are likely to have sons or daughters.

Enzyme that mutates antibodies also targets a cancer-causing oncogene

Rockefeller University scientists have discovered that the same enzyme that enables the immune system's defensive creativity is also responsible for a particular genetic malfunction - a translocation of one piece of DNA to the wrong chromosome - that causes Burkitt's lymphoma.
