As many as two of every five men whose prostate cancer was caught through a PSA screening test have tumors too slow-growing to ever be a threat, says a new study that raises more questions about the controversial tests.
The work "reinforces the message that we are overdiagnosing prostate cancer," said Dr. Len Lichtenfeld of the American Cancer Society, who was not involved in the new study.
More than 186,000 U.S. men will be diagnosed with prostate cancer this year, and nearly 29,000 will die, according to cancer society estimates. Most men over 50 have had a blood test that measures prostate specific antigen, or PSA, mostly for routine screening.

There is a wealth of research showing how our furry friends are good medicine. It is no mystery to pet lovers.
"They know you're having a bad day and just sit next to you and it really just creates a calmness," said Nancy Eickoff, owner of an 11-year-old cat named Nala.
The anti-malaria drug quinacrine does not appear to extend the lives of people with the human form of mad cow disease, despite encouraging results from experiments with mice, British researchers said on Tuesday.
Their study of 107 volunteers showed some people who took the drug showed some improvement but that it was not possible to tell whether this was due to the medicine, researchers said.

The children of older fathers scored lower than the offspring of younger fathers on I.Q. tests and a range of other cognitive measures at 8 months old, 4 years old and 7 years old, according to a study released Monday that added to a growing body of evidence suggesting risks to postponing fatherhood.
The study is the first to show that the children of older fathers do not perform as well on cognitive tests at young ages. Although the differences in scores were slight and usually off by just a few points on average, the study's authors called the findings "unexpectedly startling."
"The older the dads were, the slightly worse the children were doing," said Dr. John J. McGrath, the paper's senior author and a professor of psychiatry at the Queensland Brain Institute in Brisbane, Australia. "The findings fit in a straight line, suggesting there may be some steady beat of mutations happening in the dad's sperm."

Taking steps to stave off diabetes and heart disease may improve a person's chances of staying mentally sharp later in life, several research teams said on Monday.
In one study, U.S. researchers found the same cluster of metabolic disorders that raise a woman's risk for heart disease and diabetes also increase her chances of memory declines later in life.
A second study found that a history of diabetes and high cholesterol hasten the rate of mental declines in people with Alzheimer's disease.

President Obama's decision to lift restrictions on federal funding for embryonic stem cell research is certain to rekindle debate in Maryland and a number of other states that moved to pay for the controversial science after the Bush administration's limitation order but are now facing large budget gaps.
To try to keep Maryland's vibrant biotechnology sector competitive, state lawmakers have approved $56 million in grants to university and private-sector researchers over the past three years. Gov. Martin O'Malley (D) included an additional $18.4 million in his budget proposal for next year, even as numerous other state programs were cut to close a potential $2 billion shortfall.

Warmer weather leads to an increase in severe headaches, such as migraines, that send people to hospital emergency rooms 24 hours later, according to a Harvard University study.
Patients' risk of getting a severe headache increased 7.5 percent for every 9-degree Fahrenheit rise in outdoor temperature in the preceding two to three days, according to the study, published in the journal Neurology. Lower barometric pressure, a reading that reflects humidity as well as temperature, also increased headaches to a lesser extent.

When a child gets sick, most parents usually opt for traditional remedies like Vicks VapoRub to break up their child's congestion, instead of taking the child to campus eatery Shalimar for spicy jhinga curry. However, a recent study found that tumeric powder may actually help boost the immune system.
Turmeric powder, the main spice that gives curry its distinctive taste, has been used in India and other Asian countries as a remedy to combat fevers, colds, coughs and wounds for thousands of years. But now, after two years of research, Ayyalusamy Ramamoorthy, a professor of chemistry and biophysics, believes he has uncovered the scientific reasoning behind the powder's mysterious health benefits.
Ramamoorthy and a team of University researchers released a study last week explaining how turmeric's main ingredient, curcumin, works to cure illnesses in the human body.

The good news about the Mediterranean diet just keeps coming. New studies have shown that eating like the Mediterraneans lowers the risk of having metabolic syndrome and stroke. It also lowers the chances for mild cognitive impairment, and the risk of progression from mild cognitive impairment to Alzheimer's disease. Survivors of heart attack had lower inflammatory markers when they adhered to the Mediterranean way of eating. Scientists have even isolated one of the most beneficial components of the diet.
Chicago - Men with a higher intake of vitamin C from food or supplements have a lower risk of developing gout, a form of arthritis from uric acid build-up that causes inflamed joints, researchers said on Monday.
"Vitamin C intake may provide a useful option in the prevention of gout," Dr. Hyon Choi and colleagues at the University of British Columbia in Vancouver said in a paper published in the Archives of Internal Medicine.
