Action to prevent non-insulin dependent diabetes and heart disease in South Asian people may need to begin during childhood, finds a study in this week’s BMJ.
Researchers in London identified 3,415 white and 227 South Asian children aged 8 to 11 years from primary schools in 10 British towns. Blood samples were taken from 1,287 white and 73 South Asian children.
An early stage in the development of diabetes and heart disease risk is insulin resistance, when insulin levels are increased.
Spot-welds stick sliding metals
Two smooth, cold, metal surfaces are like pieces of tacky Sellotape. They form tiny spot welds that have to be broken apart before they can slide over each other. This, claim two physicists in California 1 , is another reason why metals stick as they slip if they are pressed together and pushed.
Such microscopic causes of friction and wear are increasingly important as the scale of mechanical engineering shrinks to below what
Weakened polio borrows genes to gain strength for outbreak
Genetic sleuthing has revealed how a dose of oral polio vaccine (OPV) can revert to the deadly poliovirus and cause an outbreak. The research highlights problems that global health organizations face completing their eradication of polio, and the urgency of that effort 1 .
“It reminds us that we need to be very careful in our development of a post-eradication policy,” says Bruce Aylward, leader of the
Pancreatic cancer is notoriously difficult to treat, largely because of the location of the pancreas close to major arteries and vital organs, and the effects of a poorly functioning pancreas on the rest of the body. It is one of the top 10 leading causes of death from cancer worldwide, and in the UK kills around 6500 people every year.
Doctors gave intravenous photosensitising agent (meso-tetrahydroxyphenyl chlorin) to 16 patients with inoperable pancreatic cancer. Three days later they ins
It may be possible to find the causes for autism in over a third of cases, suggests research in the Journal of Medical Genetics. And these are likely to include a range of factors.
Autism is a chronic and severe disorder that takes the form of severely impaired language and social skills, delayed development, and repetitive behaviours. Three times as many boys as girls are affected, and three quarters of those with autism will have a mental disability. It is thought that a combination of a g
Successful Test Observations With Powerful New Instrument at Paranal
One of the most fundamental tasks of modern astrophysics is the study of the evolution of the Universe. This is a daunting undertaking that requires extensive observations of large samples of objects in order to produce reasonably detailed maps of the distribution of galaxies in the Universe and to perform statistical analysis.
Much effort is now being put into mapping the relatively nearby space and the
Although Mars is currently a cold, dry planet, geological evidence suggests that liquid water existed there around 3 to 4 billion years ago. Where there is water, there is usually…
