A meta-analysis that included 14 randomized controlled trials with a total of 626 adult participants found that  whey protein, either as a supplement combined with resistance exercise or as part of a weight-loss or weight-maintenance diet, may provide men and women benefits related to body composition.

A small icy object within the rings of Saturn may be a new moon, according to interpretation of images taken with Cassini's narrow angle camera on April 15, 2013 which show disturbances at the very edge of Saturn's A ring -- the outermost of the planet's large, bright rings.

One of these disturbances is an arc about 20 percent brighter than its surroundings, 750 miles (1,200 kilometers) long and 6 miles (10 kilometers) wide. Scientists also found unusual protuberances in the usually smooth profile at the ring's edge. Scientists believe the arc and protuberances are caused by the gravitational effects of a nearby object. 

PULLMAN, Wash. - Happy is as happy does, apparently—for human beings all over the world. Not only does acting extroverted lead to more positive feelings across several cultures, but people also report more upbeat behavior when they feel free to be themselves.

These findings were among those recently published in the Journal of Research in Personality in a paper by Timothy Church, professor of counseling psychology and associate dean of research in the College of Education at Washington State University. The research was funded by the National Science Foundation.

University of Adelaide research into parasites of cuttlefish, squid and octopus has uncovered details of the parasites' astonishing life cycles, and shown how they may help in investigating populations of their hosts.

Researcher Dr Sarah Catalano has described 10 new parasite species− dicyemid mesozoans −, which live in the kidneys of cephalopods (cuttlefish, squid and octopus). They are the very first dicyemid species to be described from Australian waters.

The bacterium that causes whooping cough, Bordetella pertussis, has changed in Australia - most likely in response to the vaccine used to prevent the disease - with a possible reduced effectiveness of the vaccine as a result, a new study shows.

A UNSW-led team of researchers analysed strains of Bordetella pertussis from across Australia and found that many strains no longer produce a key surface protein called pertactin.

An array of tiny, metallic, U-shaped structures deposited onto a dielectric material creates a new artificial surface that can bend and focus electromagnetic waves the same way an antenna does.

Women who carry a copy of a gene variant called ApoE4 have substantially greater risk for Alzheimer's disease than men,according to an analysis of data on large numbers of older individuals who were tracked over time and noting whether they had progressed from good health to mild cognitive impairment — from which most move on to develop Alzheimer's disease within a few years — or to Alzheimer's disease itself.

Because the majority of prescriptions for depression, are given to women, men don't get a lot of concern, but depression can hit young fathers hard and the symptoms can increase dramatically during the formative years of children.

DURHAM, N.C. -- During the age of the dinosaurs, the arrival of flowering plants as competitors could have spelled doom for the ancient fern lineage. Instead, ferns diversified and flourished under the new canopy -- using a mysterious gene that helped them adapt to low-light environments.

A team led by Duke University scientists has pinpointed the curious origins of this gene and determined that it was transferred to ferns from a group of unassuming moss-like plants called hornworts. The findings were announced today, April 14, in the Proceedings of the National Academy of Sciences.

Up to 10 percent of women with family history of breast or ovarian cancer have at least one genetic mutation that would prompt their doctors to recommend changes in their care - and it isn't BRCA1 or BRCA2.

The women in the study did not have mutations in BRCA1 or BRCA2, which are strongly associated with hereditary breast and ovarian cancer, but they did have mutations in other cancer-associated genes and those were found using a multiple-gene panel to quickly and cheaply sequence just a few possible genetic culprits selected by researchers based on what is known about a disease. Although such panels are becoming widely clinically available, it's not been clear whether their use can help patients or affect medical recommendations.
