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.
