Scientists say they have found a new way to predict lung cancer – by looking at a person’s toenail clippings.
Experts at the University of San Diego in California have found that measuring nicotine levels in clippings can give a fairly accurate idea of future risk.
Slow-growing toenails provide a barometer of chronic smoke exposure the American Journal of Epidemiology says.
Men with the highest readings were over three times as likely to get lung cancer as those with the lowest.
Toenails not only spot which smokers are most at risk but also which non-smokers are as well.

Scientists have developed a new way to measure whether a person is too fat without having people step on the scale.
The new measure, called the Body Adiposity Index, or BAI, relies on height and hip measurements, and it is meant to offer a more flexible alternative to body mass index, or BMI, a ratio of height and weight, U.S. researchers said on Thursday.
BMI has been used to measure body fat for the past 200 years, but it is not without flaws, Richard Bergman of the University of Southern California, Los Angeles, and colleagues wrote in the journal Obesity. Read more…

A growing number of teens and young adults say they’ve never had sexual contact with another person, according to the largest and most in-depth federal report to date on sexual behavior, sexual attraction and sexual identity in the USA.
The study, released Thursday by the National Center for Health Statistics, reports that 27% of young men and 29% of young women ages 15-24 say they’ve never had a sexual encounter.
That’s up slightly from 22% for both males and females, in the government’s last such survey released in fall 2005, based on 2002 data.
The new findings, from...

A non-surgical autopsy technique which could remove the need to open up the body to determine a cause of death has been developed.
It involves a scanner and a small incision in the neck and has so far been shown to be 80% accurate in determining the cause of death.
Conventional post-mortem examinations require cutting open the body so the vital organs can be inspected.
The method has been developed by the University of Leicester.
The conventional autopsy process can be distressing for the family and is opposed by some communities on religious grounds.
The University of Leicester team use a Computed...

Discovering how a rare cancer heals itself could lead to new treatments for other types of the disease, claim scientists.
Researchers believe they have found a key gene involved in Ferguson-Smith disease, otherwise known as multiple self-healing squamous epithelioma (MSSE), a skin cancer that grows rapidly but then a few weeks later, inexplicably, heals itself.
They believe that by finding out how the faults in the gene TGFBR1 cause the cancer and then subsequently heal it could give valuable insights into beating other types of tumour. Read more…

Heart patients with an optimistic outlook are more likely to be healthier down the road and survive longer than those with less rosy views, new research suggests.
A study in Archives of Internal Medicine, out Monday, that followed 2,800 heart patients shows that those with more positive attitudes about their recovery had about a 30% greater chance of survival after 15 years than patients with pessimistic leanings.
Although other studies have looked at how long it was before patients returned to normal activities, this is the longest, largest study to track survival,...

(Reuters) – An experimental gel containing a prescription HIV drug has been shown for the first time to protect rectal tissue against the virus that causes AIDS, according to new research.
The gel, containing Gilead Sciences Inc’s AIDS drug tenofovir, has previously been shown to sharply reduce HIV infections in women when applied inside the vagina.
The latest study, which involved rectal tissue biopsies taken from HIV-negative men and women who used the product daily for one week, provides the first evidence that tenofovir gel could help reduce the risk of HIV from anal sex.

Extended use of a cellular telephone causes increased activity in parts of the brain next to the phone’s antenna, according to a new study in the Journal of the American Medical Association.
However, Nora Volkow, author of the paper, says it’s unclear what the clinical significance of that finding is.
This is SCIENCE FRIDAY. I’m Ira Flatow.
There has been much talk about whether cell phones may have some deleterious effect on our brains from the radio waves coming out of the antenna being held right up against your head.
Well, studies have gone back and forth on whether or...

In a promising science-fictionmeets-real-world juxtaposition, researchers at UT Southwestern Medical Centre have discovered that the mammalian newborn heart can heal itself completely.
A cure for heart disease?
Researchers, working with mice, found that a portion of the heart removed during the first week after birth grew back wholly and correctly – as if nothing had happened.
“This is an important step in our search for a cure for heart disease, the number one killer in the developed world,” said Hesham Sadek, assistant professor of internal medicine and senior author of the study...

Chronic fatigue syndrome study finds more people recover if they are helped to try to do more than they think they can
The biggest-ever study of treatments for ME, also known as chronic fatigue syndrome, has found that more people recover if they are helped to try to do more than they think they can – rather than adapting to a life of limited activity.
The findings of the study, published in the Lancet, are clear, but attracted immediate controversy. One of the biggest patient groups, Action for ME, said it was surprised and disappointed, while others denounced the trial in its entirety.
