If you liked it, then you should have put a ring on it, said cultural pundit Beyoncé Knowles about women and fingers - but that does not mean women should accept.

First, they should look at the fingers on men. Men with short index fingers and long ring fingers are on average nicer towards women, which researchers at McGill University say stems from the hormones these men have been exposed to in their mother's womb.

That  link between a biological event in fetal life and adult behavior might also explain why these men tend to have more children, the authors write in Personality and Individual Differences.

Drinking coffee may  lower risk of developing multiple sclerosis (MS), according to a new paper out today

For the study, researchers looked at a Swedish study of 1,629 people with MS and 2,807 healthy people, and a U.S. study of 1,159 people with MS and 1,172 healthy people. The studies characterized coffee consumption among persons with MS one and five years before MS symptoms began (as well as 10 years before MS symptoms began in the Swedish study) and compared it to coffee consumption of people who did not have MS at similar time periods.

The study also accounted for other factors such as age, sex, smoking, body mass index, and sun exposure habits.

The latest outbreak of Ebola virus disease has caused the deaths of more than 9,400 people worldwide and created an international outcry so loud even the National Institutes of Health decided to start funding work on it again. 

Parents of kids with severe autism are willing to try anything - unfortunately, a lot of people who claim to be experts in psychology and communication disorders don't understand science and may continue to try things long after they have been debunked. 

Hope and desperation among parents, along with cluelessness among people trying to help,  make the autism community especially vulnerable to interventions and "therapies" that have been thoroughly discredited. Yet they persist. 

A connection between persistent insomnia and increased inflammation and mortality from all causes has been identified by a group of researchers in The American Journal of Medicine.

The results apply to those with persistent insomnia, not intermittent insomnia. Persistent (chronic) insomnia affects up to 10 percent of U.S. adults. 

In the first U.S. study of urinary arsenic in babies, Dartmouth College researchers found that formula-fed infants had higher arsenic levels than breast-fed infants, and that breast milk itself contained very low arsenic concentrations.

The findings appear Feb. 23 online in the journal Environmental Health Perspectives. A PDF is available on request.

The researchers measured arsenic in home tap water, urine from 72 six-week-old infants and breast milk from nine women in New Hampshire. Urinary arsenic was 7.5 times lower for breast-fed than formula-fed infants. The highest tap water arsenic concentrations far exceeded the arsenic concentrations in powdered formulas, but for the majority of the study's participants, both the powder and water contributed to exposure.
