The human mind can rapidly absorb and analyze new information as it flits from thought to thought. These quickly changing brain states may be encoded by synchronization of brain waves across different brain regions, according to a new study.

Researchers find that being in a group makes some people lose touch with their personal moral beliefs. When people get together in groups, unusual things can happen -- both good and bad. Groups create important social institutions that an individual could not achieve alone, but there can be a darker side to such alliances: Belonging to a group makes people more likely to harm others outside the group.

A class of drug currently being used to treat leukemia has the unexpected side-effect of boosting immune responses against many different cancers, reports a new study. The drugs, called p110´ inhibitors, have shown such remarkable efficacy against certain leukemias in recent clinical trials that patients on the placebo were switched to the real drug. Until now, however, they have not been tested in other types of cancer.

A form of quantum weirdness is a key ingredient for building quantum computers according to new research. Researchers have shown that a weird aspect of quantum theory called contextuality is a necessary resource to achieve the so-called magic required for universal quantum computation.

Astronomers have for the first time directly mapped out the molecular gas and dust in the host galaxies of gamma-ray bursts (GRBs) — the biggest explosions in the universe. In a complete surprise, less gas was observed than expected, and correspondingly much more dust, making some GRBs appear as "dark GRBs".

A major fossil discovery in Canada sheds new light on the development of the earliest vertebrates, including the origin of jaws, the first time this feature has been seen so early in the fossil record.

An international team of researchers has shown that circulating avian influenza viruses contain all the genetic ingredients necessary to underpin the emergence of a virus similar to the deadly 1918 influenza virus.

DARPA's Z-Man program has demonstrated the first known human climbing of a glass wall using climbing devices inspired by geckos. The historic ascent involved a 218-pound climber ascending and descending 25 feet of glass, while also carrying an additional 50-pound load in one trial, with no climbing equipment other than a pair of hand-held, gecko-inspired paddles. A novel polymer microstructure technology was used in those paddles.

A scientific study in six European countries has analyzed the role that parents play in the risk of their children consuming alcohol, tobacco and cannabis. Both an irresponsible permissive attitude and demand are associated with higher drug use than those upbringings which encourage a good relationship with children.

Researchers have identified the evolutionary origins of human herpes simplex virus (HSV) -1 and -2, reporting that the former infected hominids before their evolutionary split from chimpanzees 6 million years ago while the latter jumped from ancient chimpanzees to ancestors of modern humans -- Homo erectus -- approximately 1.6 million years ago.

Scientists have modified mosquitoes to produce sperm that will only create males, pioneering a fresh approach to eradicating malaria. Since 2000, increased prevention and control measures have reduced global malaria mortality rates by 42 per cent, but the disease remains a prevalent killer especially in vulnerable sub-Saharan African regions. Malaria control has also been threatened by the spread of insecticide resistant mosquitoes and malaria parasites resistant to drugs.

The axiom that stress, emotional shock, or overexertion may trigger heart attacks in vulnerable people may now be explainable, researchers say. Hormones released during these events appear to cause bacterial biofilms on arterial walls to disperse, allowing plaque deposits to rupture into the bloodstream, according to research.
