Researchers make new discovery on pigment melanin and skin - hair color

The pigment melanin, which is responsible for skin and hair color in mammals, is produced in specialized cells called melanocytes and then distributed to other cells. But not every cell in the complex layers of skin becomes pigmented.

Schizophrenia-linked gene keeps new adult brain cells under control

The study reveals that the gene, known as Disrupted-In-Schizophrenia 1 (DISC1), directs the incorporation of new neurons into the adult brain and keeps the process under control. The gene's newly discovered roles might help to explain why schizophrenia's symptoms generally arise in adolescence or early adulthood, the researchers suggested.

Mutated mice provide new insights into autism

Mice containing a mutated human gene implicated in autism exhibit the poor social skills but increased intelligence akin to the title character's traits in the movie “Rain Man,” researchers at UT Southwestern Medical Center have found.

New understanding of role of schizophrenia risk gene DISC1 in normal adult brains

How the gene that has been pegged as a major risk factor for schizophrenia and other mood disorders that affect millions of Americans contributes to these diseases remains unclear.

Clearer picture of how a dividing cell rebuilds the nuclear envelope

Just how a dividing cell rebuilds the nuclear envelope, the protective, functional wrapping that encases both the original and newly copied genetic material, has been a source of controversy for the last 20 years.

Safer gene therapy - biodegradable polymers to deliver genes

In work that could lead to safe and effective techniques for gene therapy, MIT researchers have found a way to fine-tune the ability of biodegradable polymers to deliver genes.

Research highlights importance of starch in human beginnings

To think that world domination could have begun in the cheeks. That's one interpretation of a discovery, published online September 9 in Nature Genetics, which indicates that humans carry extra copies of the salivary amylase gene.

A chink in bacteria's armor

Biomedical researchers at Boston University's College of Engineering may have discovered the path toward developing better drugs capable of defeating so-called “superbugs,” bacteria that have developed resistance to common antibiotics. The researchers have discovered a previously unknown chain of events occurring in bacteria that opens to door to new avenues of research.

Racial disparities in prostate cancer, why?

African-American men face a higher risk of developing prostate cancer in their lifetime, but researchers do not fully understand why.

Adipose gene may be the key to tackle weight

Researchers at UT Southwestern Medical Center have found that a single gene might control whether or not individuals tend to pile on fat, a discovery that may point to new ways to fight obesity and diabetes.

Selection on genes underlying schizophrenia during human evolution

Several genes with strong associations to schizophrenia have evolved rapidly due to selection during human evolution, according to new research in the Proceedings of the Royal Society B (Wednesday 5 September 2007).

Quick microchip test for dangerous and drug resistant bacteria in clinical samples

Researchers at the Veterinary Laboratories Agency in Surrey have developed microchips capable of quickly and cheaply identifying dangerous and drug resistant bacteria in clinical samples, scientists announced (Wednesday 5 September 2007) at the Society for General Microbiology's 161st Meeting at the University of Edinburgh, UK, which runs from 3-6 September 2007.

Decitabine and interferon gamma show promise for ocular melanoma that has spread

A combination of two drugs shows promise in treating a rare and therapy-resistant type of melanoma that originates in the eye and spreads to other organs, according to a new study led by Duke University Comprehensive Cancer Center researchers.

Lavender oil and tea tree oil may make boy's breasts bigger

A study published in this week's issue of the New England Journal of Medicine suggests that repeated topical use of products containing lavender oil and/or tea tree oil may cause prepubertal gynecomastia, a rare condition resulting in enlarged breast tissue in boys prior to puberty, and for which a cause is seldom identified.
