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…
No one yet knows exactly. But researchers at the National Institute of Standards and Technology (NIST) have clocked their speed—and it's fast. At up to 150,000…
This is a device for patients self-determination of implanted cardioverter-defibrillators (ICD) therapy delivery. Depending on symptoms of the patient, he can decide himself to abort or delay ICD-therapy and thereby effectively
prevent inappropriate ICD therapy.
Scientists from the Universities of Göttingen and Copenhagen have modelled the formation of the oldest known star in the Milky Way using high-resolution…
Astronomers using the NASA/ESA Hubble Space Telescope have probed the extreme outskirts of the stunning elliptical galaxy Centaurus A. The galaxy’s halo of…
The laser may play a crucial role in the development of quantum computers, which are predicted to eventually outperform today's most powerful supercomputers.
While the basic physics of two interacting particles is well understood, the mathematical description of a three- or many-body system becomes increasingly…
A team of researchers led by Xiang Zhang, UC Berkeley professor of mechanical engineering, has found a way to dramatically increase the sensitivity of a…
New research published today in the journal Astrobiology shows the vital role of oceans in moderating climate on Earth-like planets.
The world is mostly neutral. That is, most of the atoms in our environment are electrically neutral. The number of electrons in the outer parts of atoms equals…
The U.S. Department of Energy's Office of Science and the National Science Foundation recently gave the go-ahead to LUX-Zeplin (LZ), a key experiment in the…
The pits range in size from about 5 meters (~5 yards) across to more than 900 meters (~984 yards) in diameter, and three of them were first identified using…
Researchers at the University of Illinois at Urbana-Champaign have demonstrated that an array of novel gold, pillar-bowtie nanoantennas (pBNAs) can be used…
The invention allows placing structures specifically in the centre of the depressions in the nanometer range. The specific binding in the centre is particularly suited for single-molecule applications, single-molecule sequencing and other high-throughput methods.
Big websites usually maintain their own “data centers,” banks of tens or even hundreds of thousands of servers, all passing data back and forth to field users'…
Using a newly developed, ultrafast femtosecond infrared light source, chemists at the University of Chicago have been able to directly visualize the…
Scientists running the ATLAS experiment at the Large Hadron Collider (LHC), the world’s largest and most powerful “atom smasher,” report the first evidence of…
