Stanford researchers unmask proteins in telomerase

One of the more intriguing workhorses of the cell, a protein conglomerate called telomerase, has in its short history been implicated in some critical areas of medicine including cancer, aging and keeping stem cells healthy.

Novel approach may lead to safer delivery of genetic therapies

A novel strategy for circumventing safety problems that have plagued gene therapy has been offered by a complex multicenter group of researchers, including Professor Claudio Napoli, a Full Professor at the II University of Naples and Adjunct Professor at the Sbarro Research Institute for Cancer Research and Molecular Medicine and the Center of Biotechnology at the College of Science and Technology of Temple University.

New genetic clue to Parkinson's disease

Researchers at Rhode Island Hospital and The Warren Alpert Medical School of Brown University have discovered a gene that could hold the key to developing new treatments for Parkinson's disease – a progressive and often debilitating movement disorder that affects as many as one million Americans.

New insight into radiation damage to DNA

A new technique for assessing the damage radiation causes to DNA indicates that the spatial arrangement of damaged sites, or lesions, is more important than the number of lesions in determining the severity of the damage.

Jumping gene may contribute to Cockayne syndrome

Scientists have identified a fusion protein that may contribute to Cockayne syndrome, a devastating disease characterized by developmental defects, neurodegeneration, severe wasting, and premature aging.

Discovery of new effect for insulin

Researchers at the Joslin Diabetes Center have shown that insulin has a previously unknown effect that plays a role in aging and lifespan, a finding that could ultimately provide a mechanism for gene manipulations that could help people live longer and healthier lives.

How humans make up for an 'inborn' vitamin C deficiency

A new study appears to explain how humans, along with other higher primates, guinea pigs and fruit bats, get by with what some have called an “inborn metabolic error”: an inability to produce vitamin C from glucose.

Are dual cord blood banks the answer to increasing stem cell demand?

In this week's BMJ, two senior doctors, Professors Nicholas Fisk and Rifat Atun, analyse the UK's growing cord blood banking industry and the potential impact of a new bank that provides blood for both personal and public use.
