Transiting exoplanet with longest known year: 704 Earth days Posted: 21 Jul 2014 11:22 AM PDT Astronomers have discovered a transiting exoplanet with the longest known year. Kepler-421b circles its star once every 704 days. In comparison, Mars orbits our Sun once every 780 days. Most of the 1,800-plus exoplanets discovered to date are much closer to their stars and have much shorter orbital periods.

More than glitter: How gold nanoparticles easily penetrate cells, making them useful for delivering drugs Posted: 21 Jul 2014 09:39 AM PDT A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells. Scientists can now explain how gold nanoparticles easily penetrate cells, making them useful for delivering drugs.

Science and art bring back to life 300-million-year-old specimens of a primitive reptile-like vertebrate Posted: 21 Jul 2014 09:37 AM PDT Paleontologists have recreated the cranial structure of a 308-million-year-old lizard-like vertebrate that could be the earliest example of a reptile and explain the origin of all vertebrates that belong to reptiles, birds and mammals.

Mysterious dance of dwarf galaxies may force a cosmic rethink Posted: 21 Jul 2014 07:04 AM PDT The discovery that many small galaxies throughout the universe do not 'swarm' around larger ones like bees do but 'dance' in orderly disc-shaped orbits is a challenge to our understanding of how the universe formed and evolved. The researchers believe the answer may be hidden in some currently unknown physical process that governs how gas flows in the universe, although, as yet, there is no obvious mechanism that can guide dwarf galaxies into narrow planes.

Children as young as three recognize 'cuteness' in faces of people, animals Posted: 21 Jul 2014 07:01 AM PDT Children as young as three are able to recognize the same 'cute' infantile facial features in humans and animals which encourage caregiving behavior in adults, new research has shown. A study investigating whether youngsters can identify baby-like characteristics – a set of traits known as the 'baby schema' – across different species has revealed for the first time that even pre-school children rate puppies, kittens and babies as cuter than their adult counterparts.

Sea level rising in western tropical Pacific anthropogenic as result of human activity, study concludes Posted: 20 Jul 2014 05:43 PM PDT Sea levels likely will continue to rise in the tropical Pacific Ocean off the coasts of the Philippines and northeastern Australia as humans continue to alter the climate, a study concludes. The study authors combined past sea level data gathered from both satellite altimeters and traditional tide gauges as part of the study. The goal was to find out how much a naturally occurring climate phenomenon called the Pacific Decadal Oscillation, or PDO, influences sea rise patterns in the Pacific.
