Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…
Physicists will soon have a better measure of the age of our galaxy, thanks to experiments described in a trio of papers appearing in the journal Physical…
The data Lawler analyzed have been available for several years, but have not been well understood until now. “The pattern looked so mysterious and…
Trapping light means either stopping the light temporally or confining the light in space. Scientists have also been able to trap a light pulse in a tiny…
The new model addresses both cylindrical pores and tapering pores that simulate the á–hemolysin membrane channel. “Current models do not take into account the…
“The goal of this work is to provide a test case for quantum dynamics theory,” says author Kenneth C. Janda of the University of California, Irvine. “It is a…
Vincent Chevrier, a research professor in the Arkansas Center for Space and Planetary Sciences, will work with graduate student Jennifer Hanley to analyze data…
Many fluorescent dyes are based upon chromophores with a highly delocalised p-system. Especially functional rylene type dyes are of great technical importance…
This invention provides an opportunity for an easy formation of highly ordered hexagonal boron nitride in a three-step process. The starting material is less…
The resulting discovery of dark energy and the accelerating universe rewrote our understanding of the cosmos. Yet the origin of these supernovae, which have…
Specific properties of metal such as elasticity, strength and anisotropy are usually gained from uni-axial experiments which simplify the material stress. But…
The two areas of online transaction processing (OLTP) and online analytical processing (OLAP) present different challenges for database architectures. We present an efficient hybrid system, called HyPer, that can handle both OLTP
and OLAP simultaneously with unprecedented high transaction rates as high as several 100000 per second and ultra-low OLAP query response times of as low as 10 ms. Moreover one can creates transaction consistent backup archives of the entire database.
Multimedia talking touchscreens, housed in computer kiosks at clinics and hospitals, are helping researchers at Northwestern University Feinberg School of…
A major breakthrough in remote wave sensing by a team of Rensselaer Polytechnic Institute researchers opens the way for detecting hidden explosives, chemical,…
Galaxies like our own were built billions of years ago from a deluge of giant clouds of gas, some of which continue to rain down. Now new calculations tie the…
Rice physicist Junichiro Kono and his team have been studying the Aharonov-Bohm effect — the interaction between electrically charged particles and magnetic…
Pharmacological inhibition of inflammatory responses in humans is pivotal in a wide variety of disease states. A prominent protein associated with inflammatory…
