Members of the international STAR collaboration at the Relativistic Heavy Ion Collider have detected the antimatter partner of the helium nucleus: antihelium-4. This new particle, also known as the anti-alpha, is the heaviest antinucleus ever detected.
New York Univ.'s Courant Institute of Mathematical Sciences has received a grant from the U.S. Office of Naval Research (ONR) to develop a bird-sized, self-flying plane that could navigate through both forests and urban environments.
The Earth may be able to recover from rising carbon dioxide emissions faster than previously thought, according to evidence from a prehistoric event analyzed by a Purdue Univ.-led team.
Los Alamos National Laboratory scientists have developed a way to avoid the use of expensive platinum in hydrogen fuel cells, the environmentally friendly devices that might replace current power sources in everything from personal data devices to automobiles.
A better understanding of corrosion resistance may be possible using a data-mining tool, according to Penn State material scientists. This tool may also aid research in other areas where massive amounts of information exist.
A leading nanotechnology scientist has raised questions over a billion dollar industry by boldly claiming that there is a limit to how small nanotechnology materials can be mass produced.
Did the early universe have just one spatial dimension? That's the mind-boggling concept at the heart of a theory that Univ. at Buffalo physicist Dejan Stojkovic and colleagues proposed in 2010. Now, in a new paper in Physical Review Letters , Stojkovic and Loyola Marymount Univ. physicist Jonas Mureika describes a test that could prove or disprove the "vanishing dimensions" hypothesis.
Researchers from North Carolina State Univ. have discovered how fat, oil and grease (FOG) can create hardened deposits in sewer lines: it turns into soap. The hardened deposits, which can look like stalactites, contribute to sewer overflows.
JBEI and Berkeley Lab researchers have demonstrated a new technique for the metabolic engineering of microbes that speeds up and improves the identification and quantification of proteins within a cell or organism. The new technique is called "targeted proteomics."
Researchers at Rice Univ. and Texas A&M have discovered a way to pattern active proteins into bio-friendly fibers. The "eureka" moment came about because somebody forgot to clean up the lab one night.
An MIT graduate student is working to make water available for the world’s poor by refining the tools and techniques of fog harvesting.
Optogenetic technology restores visual behavior in mice, holds promise for treating human blindness.
Researchers at the Univ. of California, Santa Barbara, say they've figured out the cause of a problem that's made light-emitting diodes (LEDs) impractical for general lighting purposes. Their work will help engineers develop a new generation of high-performance, energy-efficient lighting that could replace incandescent and fluorescent bulbs.
A research team from the UCLA Henry Samueli School of Engineering and Applied Science has proposed and demonstrated a new approach to producing nanocrystals with predictable shapes by utilizing surfactants, biomolecules that can bind selectively to certain facets of the crystals' exposed surfaces.
Stanford researchers have developed a new biosensor microchip that could significantly speed up the process of drug development. The microchips, packed with highly sensitive "nanosensors," analyze how proteins bind to one another, a critical step for evaluating the effectiveness and possible side effects of a potential medication.
Companies spend millions to develop their brand's personality, in hopes that it can help sell products. But they've had no way of measuring whether that personality actually appeals to consumers. Now, research from North Carolina State Univ. lays out a system for measuring the appeal of a brand’s personality.
Researchers at Lawrence Livermore National Laboratory (LLNL) have found that soldiers using military helmets one size larger and with thicker pads could reduce the severity of traumatic brain injury (TBI) from blunt and ballistic impacts.
A Univ. of Pittsburgh-led team has created a single-electron transistor that provides a building block for new, more powerful computer memories, advanced electronic materials, and the basic components of quantum computers.
By striving for control and perfection in everything from computer chips to commercial jets, scientists and engineers actually exclude a fundamental force that allows nature to outperform even their best efforts. Although it may appear to defy logic, imperfections, and the seemingly randomness among even the lowly bacteria help keep nature a couple of steps ahead, according to Oak Ridge National Laboratory researchers.
Once called "junk DNA" because it contains numerous repeated short sequences that don't code for proteins, heterochromatin is in fact vital for normal growth and function. Yet it poses special challenges to accurate DNA repair. Berkeley Lab life scientists have discovered an unsuspected and dramatic process by which double-strand breaks in heterochromatin are repaired in dynamic stages.
The hottest stars in the universe spin so fast that they get a bit squished at their poles and dimmer around their middle. The 90-year-old theory that predicts the extent of this "gravity darkening" phenomenon has major flaws, according to a new study led by Univ. of Michigan astronomers.
This month, thousands of middle-school students are going online to play an interactive video game. That might not sound surprising, by itself. But in this case, the game is a special science-mystery project, "Vanished," created by MIT researchers on behalf of the Smithsonian Institution, as a novel experiment in alternative science education.
Berkeley Lab researchers have achieved plasmonic properties in the semiconductor nanocrystals known as quantum dots. Until now plasmonic properties have been limited to nanostructures that feature interfaces between noble metals and dielectrics. This new discovery should make the already hot field of plasmonic technology even hotter.
For the first time, scientists have made star-shaped, biodegradable polymers that can self-assemble into hollow, nanofiber spheres, and when the spheres are injected with cells into wounds, these spheres biodegrade, but the cells live on to form new tissue.
Researchers from North Carolina State Univ. have created a range of soft, elastic gels that change color when exposed to ultraviolet (UV) light—and change back when the UV light is removed or the material is heated up.
