Bees under threat from disease-carrying bumblebee imports, research reveals Posted: 17 Jul 2013 06:20 PM PDT Stricter controls over bumblebee imports to the UK are urgently required to prevent diseases spreading to native bumblebees and honeybees, scientists have warned. The call follows the discovery of parasites in over three-quarters of imported bumblebee colonies they tested.

New evidence for warm-blooded dinosaurs Posted: 17 Jul 2013 04:49 PM PDT A scientist in Australia has shown new evidence that dinosaurs were warm-blooded like birds and mammals, not cold-blooded like reptiles as commonly believed. The researchers argues that cold-blooded dinosaurs would not have had the required muscular power to prey on other animals and dominate over mammals as they did throughout the Mesozoic period.

80 percent of Malaysian Borneo degraded by logging Posted: 17 Jul 2013 02:30 PM PDT A new study has found that more than 80 percent of tropical forests in Malaysian Borneo have been heavily impacted by logging. The team used the Carnegie Landsat Analysis System-lite (CLASlite) to reveal the vast and previously unmapped extent of heavily logged forest. CLASlite's high-resolution satellite imaging uncovered logging roads in Brunei and in the Malaysian states of Sabah and Sarawak on the island of Borneo.

High tooth replacement rates in largest dinosaurs contributed to their evolutionary success Posted: 17 Jul 2013 02:28 PM PDT Rapid tooth replacement by sauropods, the largest dinosaurs in the fossil record, likely contributed to their evolutionary success, according to a new article. The study also hypothesizes that differences in tooth replacement rates among the giant herbivores likely meant their diets varied, an important factor that allowed multiple species to share the same ecosystems for several million years.

The best defense against catastrophic storms: Mother Nature, researchers say Posted: 17 Jul 2013 01:44 PM PDT Researchers say that natural habitats such as dunes and reefs are the best protection against storms and rising sea levels along the U.S. coastline.

Discovery of stone monument adds new chapter to ancient Maya history: New World 'Cleopatra story' waits 1,000 years to be retold Posted: 17 Jul 2013 01:41 PM PDT Archaeologists tunneling beneath the main temple of the ancient Maya city of El Perú-Waka' in Guatemala have discovered a stone monument with hieroglyphic text detailing the exploits of a little-known sixth-century princess whose progeny prevailed in a bloody struggle between two of the civilization's most powerful royal dynasties.

Great white sharks' fuel for oceanic voyages: Liver oil Posted: 17 Jul 2013 10:49 AM PDT New research shows that great white sharks power their nonstop journeys of more than 2,500 miles with energy stored as fat and oil in their massive livers. The findings provide novel insights into the biology of these ocean predators.

BPA and chlorine means bad news: Modified forms of bisphenol A found to alter hormone signaling in new, disturbing ways Posted: 17 Jul 2013 10:24 AM PDT The ubiquity of the endocrine-disrupting chemical bisphenol A led researchers to ask what it might be doing in publicly supplied, chlorinated drinking water. The answer: Chlorinated BPA has different, but no less profound effects on cell-signaling networks than unmodified BPA.

How rice twice became a crop and twice became a weed -- and what it means for the future Posted: 17 Jul 2013 10:24 AM PDT With the help of modern genetic technology and the resources of the International Rice GeneBank, which contains more than 112,000 different types of rice, evolutionary biologist Kenneth Olsen has been able to look back in time at the double domestication of rice (in Asia and in Africa) and its double "de-domestication" to form two weedy strains. Olsen predicts the introduction of pesticide-resistant rice will drive ever faster adaptation in weedy rice.

Big-nosed, long-horned dinosaur discovered in Utah: Dinosaur in same family as Triceratops Posted: 17 Jul 2013 10:23 AM PDT A remarkable new species of horned dinosaur has been unearthed in Grand Staircase-Escalante National Monument, southern Utah. The huge plant-eater inhabited Laramidia, a landmass formed when a shallow sea flooded the central region of North America, isolating western and eastern portions for millions of years during the Late Cretaceous Period. The newly discovered dinosaur belongs to the same family as the famous Triceratops.

Molecular switch controls the destiny of self-eating cells Posted: 17 Jul 2013 10:22 AM PDT Researchers have discovered a previously unknown mechanism that controls whether a cell survives autophagy, a process that can be compared to the cell consuming parts of itself. The discovery means that it might now be possible to influence the process, which is involved in a wide variety of diseases.

Elastic electronics: Stretchable gold conductor grows its own wires Posted: 17 Jul 2013 10:22 AM PDT Networks of spherical nanoparticles embedded in elastic materials may make the best stretchy conductors yet, engineering researchers have discovered.

New Anagnorisma moth species from beautiful Binaloud Mountain Iran Posted: 17 Jul 2013 08:45 AM PDT Researchers have described a new species of Noctuidae moth from Iran, which is the fifth described species of the genus Anagnorisma. The new species belongs to the owlet moths (family Noctuidae). which are a large worldwide group of more than 20,000 species of nocturnal lepidopterans.

Deciphering butterflies' designer colors: Findings could inspire new hue-changing materials Posted: 17 Jul 2013 07:59 AM PDT Scientists have uncovered how subtle differences in the tiny crystals of butterfly wings create stunningly varied patterns of color even among closely related species. The discovery could lead to new coatings for manufactured materials that could change color by design, if researchers can figure out how to replicate the wings' light-manipulating properties.

A lost frog in the lost world? Posted: 17 Jul 2013 07:58 AM PDT Ecotourism and Conservation - Can it work? In the context of a study in the forests of Central Guyana, scientists investigated this very question and by chance found a previously undiscovered species of frog that only exists in a very confined area of the so-called Iwokrama Forest.

Monkey nation: Mainland Africa's most important nation for primates Posted: 17 Jul 2013 07:58 AM PDT A five-year study gives new hope to some of the world's most endangered primates by establishing a roadmap to protect all 27 species in Tanzania – mainland Africa's most primate-diverse country.

Stop marine pollution to protect kelp forests Posted: 17 Jul 2013 06:52 AM PDT Marine biologists have found that reducing nutrient pollution in coastal marine environments should help protect kelp forests from the damaging effects of rising CO2.

Newly discovered flux in Earth may solve missing-mantle mystery Posted: 17 Jul 2013 02:18 AM PDT Researchers have identified a "hidden flux" of material in Earth's mantle that would make the planet's overall composition much more similar to that of meteorites.

Parasites change bees brains, but not their behavior Posted: 17 Jul 2013 02:17 AM PDT Honey bees infected with the parasitic mite, Varroa destructor, or the microsporidia, Nosema ceranae, have changes in the chemical profile of their skin and in their brains. Despite this, parasitized bees were not expelled from the hive, which, the authors say, supports the hypothesis that stressed bees leave the hive altruistically to prevent the spread of infection.

Family tree of fish yields surprises Posted: 17 Jul 2013 02:17 AM PDT The mighty tuna is more closely related to the dainty seahorse than to a marlin or sailfish. That is one of the surprises from the first comprehensive family tree, or phylogeny, of the "spiny-rayed fish," a group that includes about a third of all living vertebrate species.
