Scientists at Princeton University are composing the complex codes designed to instruct a new class of powerful computers that will allow researchers to tackle problems that were previously too difficult to solve. These supercomputers, operating at a speed called the "exascale," will produce realistic simulations of complex phenomena in nature such as fusion reactions, earthquakes, and climate change.
A team of bioengineers and biochemists from Penn State University has demonstrated a device about the size of a dime that is capable of manipulating objects, including living materials such as blood cells and entire small organisms, using sound waves. The device, called acoustic tweezers, is the first technology capable of touchlessly trapping and manipulating Caenorhabditis elegans .
Gold is not necessarily precious—at least not as a coating on atomic force microscope (AFM) probes. JILA researchers found that removing an AFM probe's gold coating—until now considered helpful—greatly improved force measurements performed in a liquid, the medium favored for biophysical studies such as stretching DNA or unfolding proteins.
Several approaches have been used to remove arsenic from water in the laboratory, but most have proved to be inadequate for wide-scale use, and especially for sustainable implementations. Now, researchers at Yale University have developed a novel approach that can remove arsenic from water with high efficacy, and has the potential to be implemented sustainably.
On the morning of July 4, CERN will hold a seminar to announce the latest results from ATLAS and CMS, two major experiments at the Large Hadron Collider that are searching for the Higgs boson. Both experimental teams are working down to the wire to finish analyzing their data, and to determine exactly what can be said about what they’ve found.
A first-of-its-kind self-evaluation model and survey will provide utilities with a way to benchmark and measure their cybersecurity readiness. Announced by U.S. Energy Secretary Steven Chu, the Electricity Sector Cybersecurity Capability Maturity Model, or ES-C2M2, and evaluation survey will help utilities assess their own level of cybersecurity.
In a bold plan unveiled Thursday, a group of ex-NASA astronauts and scientists wants to launch its own space telescope to spot and track small and mid-sized space rocks capable of wiping out a city or continent. They contend that while astronomers routinely look for planet killers like the one that may have wiped out the dinosaurs, not enough attention is paid to smaller objects.
Researchers at Rice University have developed a lithium-ion battery that can be painted on virtually any surface. The rechargeable battery created in the laboratory of Rice materials scientist Pulickel Ajayan consists of spray-painted layers, each representing the components in a traditional battery.
Stanford University researchers have invented an electrically conductive hydrogel that is quick and easy to make, can be patterned onto surfaces with an inkjet printer, and demonstrates unprecedented electrical performance. This combination of characteristics hold promise for biological sensors and futuristic energy storage devices.
Lithium-ion batteries drive devices from electric cars to smartphones. And society is demanding more batteries with more capacity from each battery. To help meet this demand, Pacific Northwest National Laboratory's Environmental Molecular Science Laboratory users and researchers put their energy behind a clever new idea that, literally, gives batteries a bit of room to grow.
Researchers donned safety glasses and put their arms into a high-purity, inert atmosphere glove box recently, to prepare protein samples for neutron scattering on the Cold Neutron Chopper Spectrometer at the Spallation Neutron Source at Oak Ridge National Laboratory. In their experiment, they are using picosecond time lengths to study the dynamics of green fluorescent protein.
The Secure Shell, or SSH, is a popular program that lets computer users log onto remote machines. First release in 1995, SSH was designed for an Internet consisting of stationary machines, and it hasn't evolved with the mobile Internet. It also can't handle roaming. Now, a team of Massachusetts Institute of Technology researchs have developed a new remote-login program called Mosh, for mobile shell, which solves many of SSH's problems.
In a speech Wednesday, ExxonMobil CEO Rex Tillerson said fears about climate change, drilling, and energy dependence are overblown. He acknowledged that burning of fossil fuels is warming the planet, but said society will be able to adapt and dependence on other nations for oil is not a concern as long as access to supply is certain.
With the help of intense coherent X-ray pulses from the Linac Coherent Light Source free-electron laser, Lawrence Livermore National Laboratory researchers and international collaborators have, for the first time, peered into the makeup of complex airborne particulate matter so small that it can be transported into human lungs—usually without a trace.
Researchers at the California Institute of Technology have recently been able, for the first time, to watch viruses infecting individual bacteria by transferring their DNA, and to measure the rate at which that transfer occurs. Previous studies have involved bulk measurements, but the new technique can see the actions of individual viruses.
