Humans may have domesticated dogs twice in both Asia and Europe, new study shows Posted June 03, 2016 13:43:21 Humans may have domesticated dogs two separate times, taming wolves both in Europe and Asia thousands of years ago, according to new research. Key points:Dogs may have been domesticated twice; in Europe, then AsiaModern dogs would share a mix of both ancestors from both continentsPigs and cats could also have been domesticated multiple times A major interna..>> view original'Baby Dragons' Hatching In Slovenia: Olm Salamander Eggs Shed Light On These Rare And Mysterious Creatures
The eggs of a rare amphibious salamander, called an Olm, have finally begun hatching after months of observation by scientists in a cave in Slovenia. These “baby dragons,” as they’re known locally, are, of course, not related to actual fire-breathing dragons of folklore, but were given the nickname due to their long, slender, almost dragon-like appearance. The olm salamander eggs were discovered in Postojna Cave in January, and scientists have been monitoring them ever since, even going so far ..>> view originalExperiments relating to Earth's inner core raise questions about its age
Earth's magnetic field (illustrated below) is sustained by liquid iron that is continuously churning in the planet's outer core. Iron that crystallizes onto the solid inner core releases latent heat, which powers convection that drives Earth's dynamo (see the article by Daniel Lathrop and Cary Forest, Physics Today, July 2011, page 40). But lately scientists have questioned whether that set of mechanisms has always provided the energy for Earth's magnetic mojo. Simulations from a 2012 study sug..>> view originalWhat we now know about the universe
NASA Announces More Than 1,200 Newly Discovered Planets2:25On Tuesday, astronomers using the Kepler Space Telescope said they had verified the existence of 1,284 newly discovered planets around distant stars, doubling the number of alien worlds detected by the probe.

Stenzel/NASA This image provided by NASA shows a barred spiral galaxy 130 million light-years away and is one of the measurements that astronomers used to come up with a faster rate of expansion of the universe.

Jun 02, 2016 05:53 PM EDT A new study involving ancient crops shed some light on how people from South East Asia end up on the African Island of Madagascar, 6,000 km away. Previously, linguistic and genetic evidences revealed that inhabitants of Madagascar share close ancestry with Malaysians, Polynesians, and other speakers of what is classed the Austronesian language family. However, archeological evidences that are found in Madagascar, which were believed to be from the first millennium, ..>> view originalKing Tut's dagger 'fell from the sky'
Valuable treasure:The sarcophagus of King Tutankhamun displayed in his burial chamber in Egypt.— Photo: AFP The iron blade of an ornate dagger buried in Egypt with King Tutankhamun probably came from a fallen meteorite, researchers have determined — a form of metal so prized by ancient Egyptians that they called it “iron from the sky.”The dagger, which was discovered in the folds of the wrapping around the mummified boy king, has long intrigued historians and archaeologists for its great ..>> view originalOcean fish prefer to eat dangerous microplastics rather than plankton new study finds
Dr Chelsea Rochman, an expert of the impact of plastic debris in fish, reviewed the findings for the journal and said "the pattern is not unique." She said: "For many chemical contaminants in the environment, widespread contamination is documented, yet little is known about their ecological impacts." The mechanisms by which microplastics impact eggs, embryos and larvae of aquatic organisms, which are particularly vulnerable to water borne pollutants, are especially murky. The researchers said s..>> view originalAstronomers just picked up a hydrogen signal from this galaxy 5 billion light-years away
Scientists have broken a new astronomical record, detecting the faint signal of hydrogen in an extremely distant galaxy located some 5 billion light-years away. The team made the find using the Very Large Array of the National Radio Astronomy Observatory in New Mexico, which just had a substantial upgrade to the antennae, allowing them to pick up on hydrogen signals from almost double the distance of the previous record. "Due to the upgrade of the Very Large Array, this is the first time we've..>> view originalJupiter: Radio map shows planet's stormy weather has deep roots
