Alzheimer's Gene Found to Affect Women Over Men

A gene that's been known for two decades as the largest inheritable risk for developing Alzheimer's disease mostly affects the brains of women, not men, according to a team of researchers from Stanford and UCSF...

Bonobos Join Chimps as Closest Human Relatives

Chimpanzees now have to share the distinction of being our closest living relative in the animal kingdom. An international team of researchers has sequenced the genome of the bonobo for the first time, confirming that it shares the same percentage of its DNA with us as chimps do. The team also found some small but tantalizing differences in the genomes of the three species--differences that may explain how bonobos and chimpanzees don't look or act like us even though we share about 99% of our DNA...

Tropical Lakes on Saturn Moon Could Expand Options for Life

Nestling among the dunes in the dry equatorial region of Saturn's moon Titan is what appears to be a hydrocarbon lake. The observation, by the Cassini spacecraft, suggests that oases of liquid methane -- which might be a crucible for life -- lie beneath the moon's surface. The work is published today in Nature...

To Cut Blood Pressure, Nerves Get a Jolt

In recent decades, there have been few new treatments for people with stubbornly high blood pressure. Exercise and a low-sodium diet, along with such stalwart drugs as diuretics, ACE inhibitors and beta-blockers, have made up the standard regimens. But these efforts fail in a surprising number of patients. On three or more medications, many still suffer from uncontrolled hypertension and with it a heightened risk of heart attack and stroke...

Nature vs. Nurture: Outcome Depends on Where You Live

Both nature (meaning our genes) and nurture (the environment we grow up in) are known to significantly affect traits like our height and weight, our IQ, and our chance of developing behavioural problems or autism. But how strong environmental factors are in determining each characteristic, compared with the influence of DNA, differs significantly across the country, scientists have found...

Diesel Exhausts Do Cause Cancer, Says WHO

Exhaust fumes from diesel engines do cause cancer, a panel of experts working for the World Health Organization says. It concluded that the exhausts were definitely a cause of lung cancer and may also cause tumours in the bladder. It based the findings on research in high-risk workers such as miners, railway workers and truck drivers. However, the panel said everyone should try to reduce their exposure to diesel exhaust fumes...
