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…
In a study published today, Monday, 16 may, in IOP Publishing's journal Superconductor Science and Technology, researchers have examined bismuth strontium…
Memristors, short for memory resistors, are a newly understood circuit element for the development of electronics and have inspired experts to seek ways of…
To get more insight into those processes, Meg Rosenburg and her colleagues at the California Institute of Technology, Pasadena, Calif. put together the first…
In the 1980s and '90s, competition in the computer industry was all about “clock speed” — how many megahertz, and ultimately gigahertz, a chip could boast. But…
Why is this important? Understanding supersolid helium brings us closer to understanding its close cousins superconductivity and superfluidity.Physicists had…
Maybe, maybe not. Now, as the nation’s largest providers prepare to implement usage-based pricing plans, a tool created by Georgia Tech researchers could…
Commonly known as the Basic Input/Output System (BIOS), this fundamental system firmware—computer code built into hardware—initializes the hardware when you…
Answering that question has proved difficult, partly due to conflicting evidence. In 2003, scientists showed that some species of insects have gained, lost and…
Precision timekeeping is one of the bedrock technologies of modern science and technology. It underpins precise navigation on Earth and in deep space,…
More than 500 extrasolar planets–planets that orbit stars other than the sun–have been discovered since 1995. But only in the last few years have astronomers…
Scientists in the Earth System Science Center at The University of Alabama in Huntsville will spend the next three years studying how forecast models can best…
The new interactive approach is being used commercially and in research but until now has not been formally defined, and doing so could boost its development…
Despite its prevalence in nature, researchers are still searching for the precise laws that govern the strong force. However, the recent discovery of an…
But for the first time, scientists have experimentally shown a different version of the Doppler effect at a much, much smaller level – the rotation of an…
Severe solar storms can disrupt the smooth operation of technological systems on earth, or even cause them to fail completely. Electric power outages of longer…
