Manipulating memory with light Posted: 09 Oct 2014 01:38 PM PDT Neuroscientists have used light to erase a specific memory in mice, showing how the hippocampus and cortex work together to retrieve memories.

Migrating animals' urine affects ocean chemistry Posted: 09 Oct 2014 01:38 PM PDT Tiny animals migrating from the ocean's surface to the sunlit depths release ammonia, the equivalent of our urine, that plays a significant role in marine chemistry, particularly in low-oxygen zones.

Stunning finds from ancient Greek shipwreck Posted: 09 Oct 2014 01:37 PM PDT Divers and archaeologists have retrieved stunning new finds from an ancient Greek ship that sank more than 2,000 years ago off the remote island of Antikythera. The rescued antiquities include tableware, ship components, and a giant bronze spear that would have belonged to a life-sized warrior statue.

Dissolvable silicon circuits and sensors Posted: 09 Oct 2014 12:38 PM PDT Electronic devices that dissolve completely in water, leaving behind only harmless end products, are part of a rapidly emerging class of technology. This technology suggest a new era of devices that range from green consumer electronics to 'electroceutical' therapies, to biomedical sensor systems that do their work and then disappear.

Nanoparticles get a magnetic handle: Glowing nanoparticles can be manipulated using magnetic fields Posted: 09 Oct 2014 11:16 AM PDT A long-sought goal of creating particles that can emit a colorful fluorescent glow in a biological environment, and that could be precisely manipulated into position within living cells, has been achieved.

Snakes and snake-like robots show how sidewinders conquer sandy slopes Posted: 09 Oct 2014 11:14 AM PDT The amazing ability of sidewinder snakes to quickly climb sandy slopes was once something biologists only vaguely understood and roboticists only dreamed of replicating. By studying the snakes in a unique bed of inclined sand and using a snake-like robot to test ideas spawned by observing the real animals, both biologists and roboticists have now gained long-sought insights.

Temperature and water vapor on an exoplanet mapped Posted: 09 Oct 2014 11:14 AM PDT A team of scientists has made the most detailed map yet of the temperature of an exoplanet's atmosphere and traced the amount of water it contains. The planet targeted for both of the investigations was the hot-Jupiter exoplanet WASP-43b.

Unstoppable magnetoresistance Posted: 09 Oct 2014 09:56 AM PDT Researchers have discovered a material (WTe2) with an extremely large magnetoresistance, which is the change in resistance as a material is exposed to stronger magnetic fields. The researchers exposed WTe2 to a 60-tesla magnetic field, close to the strongest magnetic field mankind can create, and observed a magnetoresistance of 13 million percent. The material's magnetoresistance displayed unlimited growth, making it the only known material without a saturation point.

Discovery of new subatomic particle, type of meson, to 'transform' understanding of fundamental force of nature Posted: 09 Oct 2014 08:26 AM PDT The discovery of a new particle will "transform our understanding" of the fundamental force of nature that binds the nuclei of atoms, researchers argue. The discovery of the new particle will help provide greater understanding of the strong interaction, the fundamental force of nature found within the protons of an atom's nucleus.

Milky Way has half the amount of dark matter as previously thought Posted: 09 Oct 2014 06:16 AM PDT A new measurement of dark matter in the Milky Way has revealed there is half as much of the mysterious substance as previously thought.
