Brain folding could be an indication of how smart a person is

A study by Melbourne scientists has provided the first direct evidence that differences in the way the surface of the human brain is folded could be an indication of how smart a person is.

Identification of first protein biomarkers to help patients with amyotrophic lateral sclerosis

A University of Pittsburgh pathologist has identified the first protein biomarkers able to diagnose patients with amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's disease) with near 100 percent accuracy. Before this finding, there were no known diagnostic biomarkers for this neurodegenerative disease.

Researchers find drug that may suppress genetic mutation using a novel screening approach

Researchers at Massachusetts General Hospital have developed a way of identifying promising new drugs that may get around a major challenge in drug discovery.

Gene discovery could improve anemia treatment in patients

Patients with inflammatory diseases such as arthritis, chronic infections and some types of cancer, often become anemic – a condition called anemia of chronic disease (ACD). While ACD rarely kills patients, it can make their lives miserable.

New method that will revolutionize the search for genes

Medical researchers know that most common human diseases, such as hypertension and diabetes, have a large genetic component. Many genes, interacting with the environment, contribute to these diseases. For researchers, a major challenge is finding all the genes involved with a particular disease.

Second-hand smoke scars and affects healing

Researchers at the University of California, Riverside have found that breathing “second-hand” smoke reduces the speed at which wounds heal, leading to greater levels of scarring.

Genetic connection between humans, mice and dogs

The discovery that humans are genetically close to mice and dogs might make people develop greater respect for life, J. Craig Venter, a major contributor to the historic mapping of the human genome, said.

New information on genetic shuffling before egg or sperm formation rewrites genetic theory

Key decisions in the genetic shuffling that occurs before eggs or sperm are formed are made earlier than thought, rewriting textbook genetics, according to recent papers from researchers at UC Davis, Harvard University and UC San Diego.

Lack of exercise causes physical and psychological setbacks

Use it or lose it, fitness experts tell us. Now a new study offers evidence that the adage really does ring true – that a lack of exercise can not only cause physical setbacks, but also psychological setbacks as well.

Stem cell personal space determines their future

Johns Hopkins scientists report that restricting the shape and personal space of human stem cells from bone marrow is more important than any known molecular signal in determining the cell type they become.

New centre for AIDS research opens in Southampton UK

International experts on HIV/AIDS were in Southampton today (Thursday 15 April) to mark the official opening of a new Centre for AIDS Research at the city's University.

Extensive gene traffic, the process of genes leaving and arriving on the chromosome

Researchers at the University of Chicago have discovered there is extensive gene “traffic”—the process of genes leaving and arriving on the chromosome—on the mammalian X chromosome. They also have overturned a conventional theory about how genes evolved on the sex chromosome.

Certain prostate cancer cell lines are unable to repair DNA damage caused by "free radicals"

Certain prostate cancer cell lines are unable to repair DNA damage caused by "free radicals," according to scientists at the National Institute of Standards and Technology (NIST) and National Institutes of Health (NIH). This type of damage has been implicated before in the development of prostate cancer.

New insights into how tumors neutralize CD8 T cells

Scientists have speculated that this may be because the immune response is not strong enough, or because it does not last long enough to have an effect. Hence the increasing efforts to develop cancer vaccines that induce, strengthen, and increase the duration of immunological attack against cancer cells.

Diabetic eye disease on the rise

With the aging of the population, the number of Americans with major eye diseases is increasing, and vision loss is becoming a major public health problem. By the year 2020, the number of people who are blind or have low vision is projected to increase substantially. These findings appear in the April issue of Archives of Ophthalmology.

Hugs and kisses halve risk of heart attack

Having a really close relationship with another person, whether it be friend, lover, or relative, can halve the risk of further heart attacks, suggests research in Heart.

Muscle stem cells morph to resemble nerve cells

Taking a major step forward in stem cell biology, researchers at The University of Texas M. D. Anderson Cancer Center have turned muscle progenitor cells — stem cells that are “committed” to becoming muscle tissue — into cells that look and act like neurons (nerve cells).

Ground-breaking discoveries relating to the formation of kidney stones

Ground-breaking discoveries relating to the formation of kidney stones have earned Flinders University researchers a grant of more than $1.2 million (Australian) from the National Institutes of Health (NIH), the major funding body for medical science in the United States.

Vast majority of college smokers don't quit

Almost 90 percent of college students who were daily smokers and 50 percent of occasional smokers were still smoking four years later, according to a study conducted at the University of Wisconsin-Madison and just published in the current issue of Health Psychology.
