Astronomers have provided the first direct evidence that an intergalactic 'wind' is stripping galaxies of star-forming gas as they fall into clusters of galaxies. The observations help explain why galaxies found in clusters are known to have relatively little gas and less star formation when compared to non-cluster or 'field' galaxies.

Atmospheric scientists looked at predictions of precipitation and cloud buoyancy in 11 different climate models and concluded that their combined effect will generate 50 percent more electrical discharges to the ground by the end of the century because of global warming. The main cause is water vapor, which fuels explosive deep convection in the atmosphere. The more convection, the greater the charge separation and the more cloud-to-ground strikes.

Astrophysicists say that magnetic clues in a meteorite outline the earliest steps in the formation of the solar system and Earth-like planets.

Computer scientists have developed software that not only detects and eradicates never-before-seen viruses and other malware, but also automatically repairs damage caused by them. The software then prevents the invader from ever infecting the computer again.

For 13 centuries, the Virupaksha Temple in Pattadakal has been one of the most recognizable landmarks in Indian art -- a towering layer cake of elaborate, hand-carved friezes populated by a bevy of Hindu deities and symbols. Now a professor of Asian art history has shown that these figures are more than just architectural decoration.

The normally bland face of Uranus has become increasingly stormy, with enormous cloud systems so bright that for the first time, amateur astronomers are able to see details in the planet's hazy blue-green atmosphere. Astronomers first observed the storms in the infrared using the Keck telescope. When amateurs learned of the storms, they turned their optical telescopes on the planet and saw different but equally impressive storms.

The ruddy color of Jupiter's Great Red Spot is likely a product of simple chemicals being broken apart by sunlight in the planet's upper atmosphere, according to a new analysis of data from NASA's Cassini mission. The results contradict the other leading theory for the origin of the spot's striking color -- that the reddish chemicals come from beneath Jupiter's clouds.

A new theory of quantum mechanics was developed by Bill Poirier, a chemical physicist. The theory discusses parallel worlds' existence and the quantum effects observed in nature.

Scientists have demonstrated for the first time that a single-dose, needleless Ebola vaccine given to primates through their noses and lungs protected them against infection for at least 21 weeks.

When food is scarce, tool use among non-human primates does not increase. This counterintuitive finding leads researchers to suggest that the driving force behind tool use is ecological opportunity -- and that the environment shapes the development of culture.

A group of researchers from Austria have sent twisted beams of light across the rooftops of Vienna. It is the first time that twisted light has been transmitted over a large distance outdoors, and could enable researchers to take advantage of the significant data-carrying capacity of light in both classical and quantum communications.

Researchers have presented the first characterization of the black pigments used in the shelters of the Remígia cave, in the Valltorta-Gassulla area, between the Valencian regions of L'Alt Maestrat and La Plana (Castelló). The objective of this study was to identify the raw material of the black pigments and the techniques used to prepare them, and to make an approach to the cultural patterns associated with the use of pigments.

Nestled among a triplet of young galaxies more than 12.5 billion light-years away is a cosmic powerhouse: a galaxy that is producing stars nearly 1,000 times faster than our own Milky Way. This energetic starburst galaxy, known as AzTEC-3, together with its gang of calmer galaxies may represent the best evidence yet that large galaxies grow from the merger of smaller ones in the early Universe, a process known as hierarchical merging.

Researchers have invented a single tiny structure that includes all the components of a battery that they say could bring about the ultimate miniaturization of energy storage components.

A major breakthrough in the development of stem cell-derived brain cells has put researchers on a firm path towards the first ever stem cell transplantations in people with Parkinson's disease. A new study presents the next generation of transplantable dopamine neurons produced from stem cells. These cells carry the same properties as the dopamine neurons found in the human brain.
