The technique lizards use to grab their grub influences how they move, according to new research. Lizards use two basic foraging techniques. In the first approach, aptly dubbed sit-and-wait, lizards spend most of their time perched in one location waiting for their prey to pass. Then, with a quick burst of speed, they run after their prey, snatching it up with their tongues. In the other form of foraging, known as wide or active foraging, lizards move constantly but very slowly in their environment, using their chemosensory system to stalk their prey.

What began as an informal presentation by a clinical linguist to a group of philosophers, has led to some surprising discoveries about the communicative language abilities of people with Autism Spectrum Disorder. While they may not make appropriate use of context or common sayings, psychologists discovered speakers with ASD have a rich array of pragmatic abilities.

New results on genetic techniques that are helping doctors diagnose and treat lung cancer have just been released. A new test helps make crucial distinctions between types of lung cancer. The researchers show the method can accurately distinguish between squamous and non-squamous forms of non-small-cell lung cancer based on the levels of different microRNA molecules found in tissue samples.

Mothers born in India and Sri Lanka are three times more likely to suffer from extreme nausea and vomiting in pregnancy than ethnic Norwegians. Earlier studies reported that 90 percent of pregnant women experience some degree of nausea and vomiting, whereas 0.5 to 2 percent have extreme nausea.

The loss of sea ice due to climate change could spell disaster for polar bears and other Arctic marine mammals. Sea ice is the common habitat feature uniting these unique and diverse Arctic inhabitants. Sea ice serves as a platform for resting and reproduction, influences the distribution of food sources, and provides a refuge from predators. The loss of sea ice poses a particularly severe threat to Arctic species, such as the hooded seal, whose natural history is closely tied to, and depends on, sea ice.

Researchers have found markers that indicate endothelial dysfunction (changes in the cells which line the blood vessels) and sub-clinical systemic inflammation can also help identify a far greater number of people at high risk for future development of type 2 diabetes.

New, long-term results from a clinical trial show that MAGE-A3 ASCI, an immune-boosting treatment for lung cancer patients, reduces the risk of relapse after surgery -- to the same extent as chemotherapy but without the side-effects of chemotherapy.

Teaching robots to understand enough about the real world to allow them act independently has proved to be much more difficult than first thought. The team behind the iCub robot believes it, like children, will learn best from its own experiences. The technologies developed on the iCub platform -- such as grasping, locomotion, interaction, and even language-action association -- are of great relevance to further advances in the field of industrial service robotics.

OSLO (Reuters) - Tests of the bones of two Viking women found in a buried longboat have dispelled 100-year-old suspicions that one was a maid sacrificed to accompany her queen into the afterlife, experts said on Friday.
WASHINGTON (Reuters) - Scraps of protein from the bones of a 68 million-year-old dinosaur and a mastodon carcass confirm their places in the family tree of life on Earth, researchers reported on Thursday.
