Grand Canyon Thought to Be 65 Million Years Older Than Previous Estimates

Posted: 03 Dec 2012 09:17 AM PST

A new analysis of the mineral grains from the bottom of the Grand Canyon indicates that it was formed about 70 million years ago, during the late Cretaceous Period, a time when dinosaurs roamed the Earth. The scientists published their findings in the journal Science. This new research pushes back the date for the formation [...]

Kitti’s Hog-Nosed Bat Is World’s Smallest Mammal

Posted: 03 Dec 2012 08:59 AM PST

The Kitti’s hog-nosed bat (Craseonycteris thonglongyai), sometimes referred to as the bumblebee bat due to its diminutive size, was discovered in 1970s and could arguably be the world’s smallest mammal, depending on how size is defined. C. thonglongyai is listed as vulnerable by the IUCN and is found in western Thailand and southeast Burma, in [...]

Hubble Views Galaxy ESO 318-13

Posted: 03 Dec 2012 08:38 AM PST

This is new image from the Hubble Space Telescope shows galaxy ESO 318-13 and other more distant galaxies, which are located millions of light-years from Earth. The brilliant cascade of stars through the middle of this image is the galaxy ESO 318-13 as seen by the NASA/ESA Hubble Space Telescope. Despite being located millions of [...]

As Supersymmetry Fails, Physicists Looking for New Models

Posted: 03 Dec 2012 08:16 AM PST

As the Large Hadron Collider has been unable to find any of the particles suggested by supersymmetry, theoretical particle physicists are trying to change their worldview, away from supersymmetry to theories that could explain the results. So far, there have been no hints beyond the Standard Model of Particle Physics from the LHC. A recent [...]

Lines on Crocodiles’ Crania Are Cracks in Skin, Not Scales

Posted: 03 Dec 2012 07:54 AM PST

The "scales" on a crocodile's cranium aren't really scales, but simple physical cracks rather than developmentally programmed scales that cover the rest of a crocodile's body. Researchers had previously assumed that the deep lines marked boundaries between scales. The scientists published their findings in the journal Science. Understanding the physical process by which the cracks [...]

New Finding Challenges Theories of How Rocky, Earth-Scale Planets Form

Posted: 03 Dec 2012 07:21 AM PST

While viewing the young brown dwarf ISO-Oph 102, an international team of astronomers pinpointed carbon monoxide gas around the brown dwarf and found that the outer region of the dusty disc encircling the brown dwarf contains millimeter-sized solid grains. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have for the first time found that the [...]
