Protein design is technique that is increasingly valuable to a variety of fields, from biochemistry to therapeutics to materials engineering. University of Pennsylvania chemists have taken this kind of design a step further; using computational methods, they have created the first custom-designed protein crystal.

Two lamps are brighter than one. This simple truism does not necessarily apply to lasers, as a team of scientists, led by the Vienna University of Technology found out. When one laser is shining and next to it another laser is turned on gradually, complex interactions between the two lasers can lead to a total shutdown and no light is emitted anymore.

An international team of researchers has reported a new understanding of a little-known process that happens in virtually every cell of our bodies.

Microscopic particles are being coaxed by Duke University engineers to assemble themselves into larger crystalline structures by the use of varying concentrations of microscopic particles and magnetic fields.

Physicists have discovered a possible solution to a mystery that has long baffled researchers working to harness fusion. If confirmed by experiment, the finding could help scientists eliminate a major impediment to the development of fusion as a clean and abundant source of energy for producing electric power.

Physicists of the group of Prof. Anton Zeilinger at the Institute for Quantum Optics and Quantum Information (IQOQI), the University of Vienna, and the Vienna Center for Quantum Science and Technology (VCQ) have, for the first time, demonstrated in an experiment that the decision whether two particles were in an entangled or in a separable quantum state can be made even after these particles have

Tiny pores, or channels, embedded in cell membranes are critical to the healthy functioning of cells. Charged atoms, or ions, move through these channels to generate the electrical signals that allow cells to communicate with one another.

Researchers from New York University and the Max Planck Institute in Stuttgart reveal how protons move in phosphoric acid in a Nature Chemistry study that sheds new light on the workings of a promising fuel cell electrolyte.

Analysis of data from the IceCube Neutrino Observatory, a massive detector deployed in deep ice at the U.S. Amundsen-Scott South Pole Station in Antarctica at the geographic South Pole, recently provided new insight into one of the most enduring mysteries in physics, the production of cosmic rays.

By developing software that uses 3-D models of proteins involved in cystic fibrosis, a team of scientists at Duke University has identified several new molecules that may ease the symptoms of the disease.

Living systems owe their existence to a pair of information-carrying molecules: DNA and RNA. These fundamental chemical forms possess two features essential for life: they display heredity—meaning they can encode and pass on genetic information, and they can adapt over time, through processes of Darwinian evolution.

The mud and clays ideal for preserving fossil records are less common around Martian lakes than on Earth. A new survey of 226 ancient lakebeds on the Red Planet reveals that only a third show evidence of such deposits on the surface today.
Watch a superthin gel flatten then regrow into a 3D shape driven by changes in temperature
An experiment inspired by a metaphorical demon demonstrates that erasing information produces heat and reveals a potential limit on the power of computer chips
Einstein's famous critique of quantum mechanics first emerged in 1930, five years earlier than thought, according to a new analysis of his work Einstein's phrase "spooky action at a distance" has become synonymous with one of the most famous episodes in the history of physics--his battle with Bohr in the 1930s over the completeness of quantum mechanics.
By tucking in cleverly behind the leaders, horses can use "aerodynamic drafting" to their advantage.
Science editor Alan Boyle's blog: In the year since Japan's earthquake put early warning systems to their sternest real-world test, researchers are capitalizing on the lessons learned.
Quantum processes shouldn't survive in hot, wet biological systems and yet a growing body of evidence suggests they do. Now physicists think they know how
3M is using carbon composite and nanoparticles to build strong and small tanks for compressed natural gas.
The mystery of how the tiny diamonds found in meteorites form in outer space has been solved
As U.S. policymakers contemplate a new era as the "Saudi Arabia of natural gas," a new government analysis slashes estimates for unproved shale gas reserves.
Since red and violet are at the opposite ends of the color spectrum, they can't mix together to make pink light.
Material conducts like graphene but in only one direction
Results could help explain why the early universe survived
Officials feared they would have to evacuate Tokyo even as they assured the public that things were under control at the Fukushima nuclear plant, a panel finds.A new report vividly portrays the Japanese government's fears in the first hours and days after the March 11, 2011, tsunami overran a coastal nuclear power plant, including concerns that officials might have to evacuate Tokyo.
The first weapon-scale prototype of a futuristic Navy railgun began undergoing firing tests last week, the next big step toward putting the electromagnetic superweapon on U.S. warships by 2020. The Navy envisions using railguns to destroy enemy ships, defend against enemy missiles, or bombard land targets in support of Marines hitting the beaches.
