There is growing consensus among scientists, regulators, politicians, industry and the public that we need to know more about the possible harmful or adverse effects of nanoparticles on human health. Likewise, most agree that these incredibly small materials can behave quite differently from conventional materials. Nonetheless, neighborhood stores feature products that promise benefits f...New stem-cell findings can help the body to cure itself
Researchers at Karolinska Institutet have identified an important mechanism that regulates how many new cells are produced by each intestinal stem cell. The study is published in the latest issue of the prestigious scientific journal, Cell. "This might eventually help us develop new drugs for things like neurological disorders and anaemia," says Professor Jonas Frisén. In most organs of th...'Smart' genetic therapy helps the body to heal itself
New approaches to genetic disease, based on cells' own ability to correct themselves, will be outlined today (Monday 8 May 2006) at the annual conference of the European Society of Human Genetics in Amsterdam, The Netherlands. Instead of replacing a faulty gene (commonly referred to as gene therapy) these new 'smart' approaches make use of the therapeutic potential that already exists in hum...Academic R&D pays for itself in jobs and economic growth
There would be little logic, however, in cu...Heart can repair itself after heart attack
Contrary to popular belief, the heart can actually repair itself by growing new cells after a heart attack. This surprising discovery was uncovered by researchers in New York and Italy. Dr. Piero Anversa and colleagues of the New York Medical College in Valhalla detected signs that heart muscle cells called myocytes continued to divide after a heart attack. Anversa's team...UK Prepares Itself For Flu Pandemic
A bird flu tsar will be appointed for Scotland for coordinating efforts when an epidemic breaks out.
