Fathers who sleep closer to children have lower testosterone levels

Posted: 05 Sep 2012 02:16 PM PDT

Closer sleeping proximity between fathers and children is associated with a greater decrease in the father's testosterone level, with possible implications for parenting behavior.

Albatross 'dynamic soaring' achieved by repeated curve-altitude oscillation

Posted: 05 Sep 2012 02:16 PM PDT

Albatrosses leverage the energy of the wind to fly with essentially no mechanical cost to themselves, very rarely flapping their wings, and new work offers insight into how exactly they accomplish this feat.

Picky penguins: Does mate choice depend on genes that help resist disease?

Posted: 05 Sep 2012 01:37 PM PDT

Magellanic penguins have a high level of variation in genes associated with the ability to fight infectious disease, but a recent study found that the mechanism the penguins use to ensure that diversity is far from black and white. A recent study tested whether the significant diversity in the Major Histocompatibility Complex genome region observed in these birds is attributable to mate choice or genetic selection based on disease exposure.

Seeing the birth of the universe in an atom of hydrogen: Radio waves used to uncover oldest galaxies yet

Posted: 05 Sep 2012 11:19 AM PDT

Astronomers are using radio telescopes to find radio waves emitted by hydrogen atoms, which were abundant in the early days of the universe. This new field of research, called "21-centimeter cosmology," opens the way to learning more about the universe's oldest galaxies.

Decoding the Black Death: Anthropologist finds clues in medieval skeletons

Posted: 05 Sep 2012 10:48 AM PDT

Researchers have been studying medieval skeletons at the Museum of London since 2003, each year unlocking more clues to the mystery that surrounds the Black Death.

Champagne proves a fantastic playground for physicists

Posted: 05 Sep 2012 09:28 AM PDT

The fleeting life of champagne bubbles intrigues scientists; collapsing bubbles are common in our everyday lives but are still not fully understood. Two reviews explore collapsing bubbles and bubble flow patterns in champagne glasses. These phenomena are of much wider interest because of the huge importance of bubbles in many natural and industrial processes.

Kinsey Reporter: Free app allows public to anonymously report, share information on sexual behavior

Posted: 05 Sep 2012 08:08 AM PDT

Indiana University has released Kinsey Reporter, a global mobile survey platform for collecting and reporting anonymous data about sexual and other intimate behaviors. The pilot project allows citizen observers around the world to use free applications now available for Apple and Android mobile platforms to not only report on sexual behavior and experiences, but also to share, explore and visualize the accumulated data.

It pays to keep salmon fit: Salmon farmers could save big by exercising their fish more -- without overexerting them

Posted: 05 Sep 2012 05:39 AM PDT

Salmon farmers could save huge sums by exercising their fish more. Researchers in Norway have tested various swimming exercise regimes for three years on salmon fry. The findings indicate that proper exercise can improve smolt health enough to significantly reduce losses at sea.

Astronomers discover 'pigtail' molecular cloud

Posted: 05 Sep 2012 05:37 AM PDT

A research team has discovered a molecular cloud with a peculiar helical structure by observation with the NRO 45m Telescope at the National Astronomical Observatory of Japan. The team named it a "pigtail" molecular cloud from its morphology. The "pigtail" molecular cloud is located in the galactic center, approximately 30,000 light years away from the solar system.

In elk hunting, success depends on the animal's personality

Posted: 04 Sep 2012 04:37 PM PDT

New research shows an elk's personality type is a big factor in whether or not it survives the hunting season. Data collected from GPS collars on more than 100 male and female elk in southwestern Alberta showed researchers the study population could be divided into two categories: bold runners and shy hiders, researchers found far more bold-runners were taken by elk hunters than shy hiders.
