1 in 7 men destined to go bald due to genes

Scientists have discovered that 1 in 7 men have a genetic risk for baldness. Researchers at Canada's McGill University and King's College London along with scientists at drug company GlaxoSmithKline have solved the mystery of male pattern baldness but say treating it will require more research.

Ultra-sensitive nanoprobes help tackle MRSA

This week Nature Nanotechnology journal (October 12th) reveals how scientists from the London Centre for Nanotechnology (LCN) at University College London are using a novel nanomechanical approach to investigate the workings of vancomycin, one of the few antibiotics that can be used to combat increasingly resistant infections such as methicillin-resistant Staphylococcus aureus (MRSA).

Male baldness gene in Caucasians discovered

Researchers at McGill University, King's College London and GlaxoSmithKline Inc. have identified two genetic variants in caucasians that together produce an astounding sevenfold increase the risk of male pattern baldness. Their results will be published Oct. 12 in the journal Nature Genetics.

'Lab-on-Bead' to speed drug discovery

Researchers at Wake Forest University are using nanotechnology to search for new cancer-fighting drugs through a process that could be up to 10,000 times faster than current methods.

When particles are so small that they seep right through skin

Scientists are finding that particles that are barely there - tiny objects known as nanoparticles that have found a home in electronics, food containers, sunscreens, and a variety of applications - can breech our most personal protective barrier: The skin.

Carbon nanotube coating improves electrical stimulation therapy used for Parkinson's, depression, chronic pain

Researchers at UT Southwestern Medical Center have designed a way to improve electrical stimulation of nerves by outfitting electrodes with the latest in chemically engineered fashion: a coating of basic black, formed from carbon nanotubes.

Scientists develop nanometer-sized 'cargo ships' to target and destroy tumors

Scientists have developed nanometer-sized 'cargo ships' that can sail throughout the body via the bloodstream without immediate detection from the body's immune radar system and ferry their cargo of anti-cancer drugs and markers into tumors that might otherwise go untreated or undetected.

Trastuzumab-DM1 - a 'smart bomb' for breast cancer treatment

Sarah Cannon Research Institute (SCRI) investigators have found that "smart bomb" therapies are effective in treating breast cancer patients while minimizing side effects.

Human herpes virus 6 weaves itself into the DNA transferred from parents to babies

Parents expect to pass on their eye or hair color, their knobby knees or their big feet to their children through their genes. But they don't expect to pass on viruses through those same genes.

Earwax removal - new guidelines

The American Academy of Otolaryngology - Head and Neck Surgery Foundation (AAO-HNSF) will issue the first comprehensive clinical guidelines to help health care practitioners identify patients with cerumen (commonly referred to as earwax) impaction. The guidelines emphasize evidence-based management of cerumen impaction by clinicians, and inform patients of the purpose of ear wax in hearing health.

Century old rule of chemistry overturned - major implications for drug delivery

A new study by research chemists at the University of Warwick has challenged a century old rule of pharmacology that defined how quickly key chemicals can pass across cell walls. The new observations of the Warwick researchers suggest that the real transport rates could be up to a hundred times slower than predicted by the century old "Overton's Rule". This could have major implications for the development and testing of many future drugs.

Researchers discover key allergy gene

Together with colleagues from the Department of Dermatology and Allergy and the Center for Allergy and Environment (ZAUM) of the Technische Universitat Munchen, scientists at the Helmholtz Zentrum Munchen have pinpointed a major gene for allergic diseases. The gene was localized using cutting edge technologies for examining the whole human genome at the Helmholtz Zentrum Munchen.

Why hormone therapy for prostate cancer fails

Some of the drugs given to many men during their fight against prostate cancer can actually spur some cancer cells to grow, researchers have found. The findings were published online this week in a pair of papers in the Proceedings of the National Academy of Sciences.

Bacterial pneumonia caused most deaths in 1918 influenza pandemic

The majority of deaths during the influenza pandemic of 1918-1919 were not caused by the influenza virus acting alone, report researchers from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. Instead, most victims succumbed to bacterial pneumonia following influenza virus infection.

Inherited form of hearing loss stems from gene mutation

Pat Phalin learned she had hearing loss at 30, when she volunteered to give hearing tests at her local school. The pupils heard sounds she could not hear.

Eroded telomeres are behind dyskeratosis congentia aging syndrome

Each time a cell divides, the protective caps at the ends of chromosomes shorten - and when these caps are gone, so are we. Now, by using an unconventional strategy to shorten telomeres in mice, researchers at Rockefeller University have not only created the first faithful mouse model for studying a rare yet fatal premature aging syndrome, but they have revealed the molecular defect behind the disease.
