New insights into ancient mating and migration patterns in humans

Men have been tomcatting around since time immemorial, and some traveled far from home to do it, new research suggests.

Possibility of developing drug therapies that target eosinophils, white blood cells long known to be associated with the asthma

The studies discount a 2000 study published in The Lancet which concluded that eosinophils do not have a significant role in the development of asthma in humans.

Jellyfish advance science

Salmon fishermen trolling along the waters off Puget Sound in Washington are often witness to an awesome sight when they haul in their catch: salmon captured in nets that glow brilliantly against the nighttime sky.

The same gene functions in vision and immune system, research shows

Scientists have learned that a family of genes long known to be integral to the immune system also plays a role in vision, perhaps preventing certain blinding diseases.

Certain people are born with an increased risk of developing alcohol problems

The Queensland Institute of Medical Research (QIMR) and the Royal Prince Alfred Hospital have determined that although alcohol consumption and alcohol dependence are closely related, the causes of susceptibility are not necessarily the same.

New method targeting hypermethylation detects ovarian cancer in the blood

Fox Chase Cancer Center researchers have found a new way to detect ovarian cancer in the blood. Reported in the Sept. 15, 2004, issue of Cancer Research, the new method targets hypermethylation--one mechanism used by cancer cells to turn off genes that protect against tumor development.

ChemGenex discovers five new depression genes

ChemGenex Pharmaceuticals has announced that it has filed for patent protection for a further five novel depression-associated gene targets discovered by its depression and anxiety research group.

Drug combo may have a greater impact on cancer development

Cancer researchers have long suggested that new targeted drugs may work best when paired with other therapies. In a new study published today in Cancer Research, scientists have taken some of the first steps to demonstrate this synergy in mouse and cell line models.

Newly completed Chromosome 5 sequence will be a powerful tool for scientists trying to understand human disease

Four years after publicly revealing the official draft human genetic sequence, researchers have reached the halfway point in dotting the i's and crossing the t's of the genetic sentences describing how to build a human.

Mighty mouse helps researchers tackle osteoporosis

A genetically engineered 'mighty mouse' is helping Medical College of Georgia researchers find the best way for young people to build bone and avoid osteoporosis.

Liver cancer genes cluster into two subsets that correlate to survival

An analysis of the gene expression patterns of 91 unrelated liver tumors revealed two distinctive subclasses highly associated with patient survival, according to a new study published in the September 2004 issue of Hepatology.

Statistical method for faster prognosis of Alzheimer’s and Parkinson’s diseases

A large number of diseases − including Alzheimer’s disease, Parkinson’s disease, and mad cow disease − are the result of proteins that erroneously assume the wrong shape, causing them to stick to each other.

Positive emotions may delay onset of frailty and negative stereotypes can influence older adults’ memory

Why do some older people experience a rapid decline in their physical and functional health while some of their peers remain healthy and active? While your genes and overall physical health play a role, new research shows how psychosocial factors can also play an important role.

$10.3 million biodefense contract to tackle salmonella, typhoid fever and monkey pox virus

Pacific Northwest National Laboratory has received a $10.3 million biodefense contract from the National Institute of Allergies and Infectious Agents (NIAID) to identify the proteins that regulate the bacteria that cause salmonella poisoning and typhoid fever, and the monkey pox virus.

New genetic test can predict cleft lip or palate

Researchers have developed a new genetic test that can help predict whether parents who have one child with the "isolated" form of cleft lip or palate are likely to have a second child with the same birth defect. Isolated clefts account for 70 percent of all cleft lip and palate cases.

New study will examine why people live exceptionally long lives

Researchers at Washington University School of Medicine in St. Louis will head an ambitious study of people who live exceptionally long and healthy lives to identify the factors that account for their longevity.

Unique technology with the potential to test for hundreds of diseases, cancers and genes in one, cheap, test

Queensland, Australia PhD student Angus Johnston has invented a unique technology with the potential to test for hundreds of diseases, cancers and genes in one, cheap, test. He hopes that within five years the technology will be available in a desktop unit for less than AU$30,000.

Suprising new information on the HOX genes

Researchers at the University of Bergen are now able to present new information on the HOX genes – the “software” to design animals. The findings are published in today’s issue of Nature.

New view of chromatin and gene activity

A genome - the DNA instructions for an organism - does not act alone. DNA is packaged with proteins into 'chromatin', which may be more or less tightly condensed. A popular proposal is that active genes are in 'open' chromatin (to allow access to them) and inactive genes are in tightly packed 'compact' chromatin.

Disruption of protein folding causes neurodegeneration, mental retardation

Excess accumulation in brain cells of a fat molecule called GM1-ganglioside (GM1) disrupts the folding of newly assembled proteins into their proper shapes, triggering nerve degeneration and mental retardation in children.
