More than half of Texas physicians do not always recommend HPV vaccine to girls

PHILADELPHIA - The Advisory Committee on Immunization Practices recommends the human papillomavirus vaccination for all 11- and 12-year-old girls, but results of a recent survey showed that more than half of Texas physicians do not follow these recommendations. The survey was published in Can...

Why the 'perfect' body isn't always perfect

Having an imperfect body may come with some substantial benefits for some women, according to a new article in the December issue of Current Anthropology . The hormones that make women physically stronger, more competitive and better able to deal with stress also tend to redistribute fat from...

Fiddler crabs reveal honesty is not always the best policy

Dishonesty may be more widespread in the animal kingdom than previously thought. A team of Australian ecologists has discovered that some male fiddler crabs "lie" about their fighting ability by growing claws that look strong and powerful but are in fact weak and puny. Published this week in the B...

Relearning process not always a 'free lunch'

Researchers at Sheffield University and the University of St. Andrews, United Kingdom, have helped determine why relearning a few pieces of information may or may not easily cause a recollection of other associated, previously learned information. The key, they find, is in the way in which the le...

People not always needed to alleviate loneliness

New research at the University of Chicago finds evidence for a clever way that people manage to alleviate the pain of loneliness: They create people in their surroundings to keep them company. Biological reproduction is not a very efficient way to alleviate ones loneliness, but you can make up ...

The insect vector always bites twice

The reality of the threat from vector-borne diseases has been recognized and the problem is prompting research scientists to take a strong interest. Most of these infections, classified as emerging or re-emerging diseases, are linked to ecosystem changes, climatic variations or pressure from human...

Physicist cracks women's random but always lucky choice of X chromosome

A University of Warwick physicist has uncovered how female cells are able to choose randomly between their two X chromosomes and why that choice is always lucky. Human males have both a X and a Y chromosome but females have two X chromosomes. This means that in an early stage in the development ...

Vitamins: Science doesn't always match policy

Some one hundred years after the first vitamin was named, what is known about them has not translated into beneficial, standardized recommendations for public health, says Irwin Rosenberg, MD, University Professor, and director of the Nutrition and Neurocognition Laboratory at the Jean Mayer USDA H...

When your brain talks, your muscles don't always listen

Have your neurons been shouting at your muscles again? It happens, you know. As we grow older, neurons--the nerve cells that deliver commands from our brains--have to "speak" more loudly to get the attention of our muscles to move, according to University of Delaware researcher Christopher Knig...

Survival of the selfless - scientists find cheats don't always prosper

Selfishness is not necessarily the best survival trait for microorganisms, according to researchers studying the comparative effectiveness of 'cheating' and 'cooperating' strains of yeast. Writing in the journal Nature today, the team reports that studies of lab-grown yeast populations suggest th...

Study finds evolution doesn't always favor bigger animals

Biologists have long believed that bigger is better when it comes to body size, since many lineages of animals, from horses to dinosaurs, have evolved into larger species over time. But a study published this week by two biologists at the University of California, San Diego in an early online ed...

Geckos: It's not always about sex

Usually when you give up something, there's a price to pay. Not so in the case of the Australian Bynoe's gecko. This line of all-female geckos doesn't need sex or a male to reproduce and, contrary to expectations, these "Wonder Woman" geckos can run farther and faster than their sexually reproducin...
