African Americans have more severe complications from scleroderma

African Americans have more severe complications from systemic sclerosis, also known as scleroderma, than Caucasians. Findings published today in, Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), show that compared with Caucasians, African-American patients were more likely to have antibodies that increased frequency and severity of pulmonary fibrosis, which is associated with decreased survival.

New technique measures brain activity in large populations of nerve cells

Researchers have developed a new technique which allows them to measure brain activity in large populations of nerve cells at the resolution of individual cells. The technique, reported today in the journal Nature, has been developed in zebrafish to represent a simplified model of how brain regions work together to flexibly control behaviour.

Genes determine brain size: Global brain study

In the world's largest study of the human brain, involving more than 200 scientists worldwide, researchers have found that genes that affect brain size may play a part in intelligence and memory function. The study was put together by combining brain scans and genetic data from 21,000 people worldwide.

MSU researcher wins Grand Challenges Explorations grant for work on TB

For his work on developing new treatments for tuberculosis, a Michigan State University researcher has been named a Grand Challenges Explorations winner, an initiative funded by the Bill & Melinda Gates Foundation.

UMD researchers design molecular container that can increase solubility of drugs

A cross-disciplinary team of researchers at the University of Maryland has designed a molecular container that can hold drug molecules and increase their solubility, in one case up to nearly 3000 times. Their discovery opens the possibility of rehabilitating drug candidates that were insufficiently soluble. It also offers an opportunity to improve successful drugs that could be made even better with better solubility.

Study: Y and W chromosomes are very important in fertility

The study, published yesterday in the journal Proceedings of the National Academy of Sciences (PNAS), looked at how genes on sex-linked chromosomes are passed down generations and linked to fertility, using the specific example of the W chromosome in female chickens.

Molecule that starts DNA repairs also halts them

Repairing DNA breaks can save a cell's life - but shutting off the repair machinery can be just as critical. How cells accomplish this feat was unknown. However, new research by Johns Hopkins scientists, published in the Feb. 22 issue of Nature, suggests that shutting down the repair machinery relies heavily on the same molecule used to start repair in the first place.

Research grants on facioscapulohumeral dystrophy prove useful as genetic basis is found

Businessman Bill Moss’s determination to fight his untreatable muscle-wasting disease may have paid off. Four years ago, Mr Moss, a former Macquarie Bank Executive Director, established a charitable research foundation, FSHD Global, which partly funded the Italian researchers who made the breakthrough.

People can take themselves from good to great

The sayings "variety is the spice of life" and "happiness isn't getting what you want, but wanting what you get" seem to have a psychological basis, according to a new study by an MU psychologist who identified two keys to becoming happier and staying that way.

Rare form of dementia eats away at personality and language

Michael French suffered from a rare form of dementia. It made him do unwise things like throwing away tax documents, getting a ticket for trying to pass an ambulance and buying stock in companies that were obviously in trouble. He seemed withdrawn and no longer spoke to his wife over dinner. He also lost his job at the consulting firm. This happened in 2006. His wife found he had changed suddenly from the smart, good-natured, hardworking man and was considering divorce when his ailment came into the picture.

Eye color linked to high-risk for skin conditions

Eye color may be an indicator of whether a person is high-risk for certain serious skin conditions. A study, led by the University of Colorado School of Medicine, shows people with blue eyes are less likely to have vitiligo.

Bionic eye helps two blind men see for the first time in 20 years

In a medical breakthrough two blind men have regained partial sight for the first time in more than 20 years after receiving a “bionic eye”. Scientists said the first clinical trials of the microchip eye implant, which measures just 3mm across and is fitted behind the eyeball, have proved successful and “exceeded expectations”.

Researchers discover two defective genes that cause auriculocondylar syndrome

Researchers at Seattle Children's Research Institute and their collaborators have discovered a pair of defective genes that cause a rare congenital malformation syndrome that can make it impossible for the child to breathe or eat properly without reparative surgery.

New genetic pathway influences spread of cancer cells

In a new study from Lawson Health Research Institute, Dr. Joseph Torchia has identified a new genetic pathway influencing the spread of cancer cells. The discovery of this mechanism could lead to new avenues for treatment.

Researchers identify switches that can turn on or off genes associated with colorectal cancer

Two researchers at the Geisel School of Medicine at Dartmouth have helped to identify switches that can turn on or off genes associated with colorectal cancer. The finding offers clues about the development of colorectal cancer and could-potentially-provide targets for new therapies.

Scientists identify first gene associated with congenital asplenia

Researchers at Weill Cornell Medical College and Rockefeller University have identified the first gene to be linked to a rare condition in which babies are born without a spleen, putting those children at risk of dying from infections they cannot defend themselves against. The gene, Nkx2.5, was shown to regulate genesis of the spleen during early development in mice.
