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…
Why it matters: A non-invasive electron microscope could shed light on fundamental questions about life and matter, allowing researchers to observe molecules…
In 1931, Paul Dirac, one of the rock stars of the physics world, made the somewhat startling prediction that “magnetic monopoles,” or particles possessing only…
However, there is currently no published standardized, repeatable methodology by which manufacturers of RFID equipment or medical devices can assess potential…
So-called 'wake fields' occur during the process of acceleration and can cause particles to fly apart.The particles are travelling at extremely high energies –…
Exploiting quantum mechanics for transmitting information is a tantalizing possibility because it promises secure, high speed communications. Unfortunately,…
This is shown in calculations of the light emission of so-called quark-gluon plasmas, which are created in such collisions for extremely short periods of time….
The goal of the six-year project is to measure the spectra of 1.4 million galaxies and 160,000 quasars, extremely distant objects that shine more brightly than…
NPL, along with collaborators, produced technical reports for the European Space Agency. The conclusions demonstrated that the lasers were a suitable method…
On 3 September, Herschel aimed its telescope at a reservoir of cold gas in the constellation of the Southern Cross near the Galactic Plane. As the telescope…

A part of the Sloan Digital Sky Survey III (SDSS-III), BOSS achieved “first light” on the night of September 14-15, when it acquired data with an upgraded…
Method for enhancement of general stress resistance, based on improved reductant supply (NADPH) in the cytosol via Glucose-6-phosphate dehydrogenase (G6PDH).
– G6PDH-isoenzyme replacement resulted in highly uniform defense responses, enhanced drought tolerance, acceler-ated flowering and increased harvest yields.
Challenge
Worldwide every year billions of US dollars worth of harvest are lost due to biotic (pathogens) and abiotic (drought, heat or salt) stress. Stress responses consume a lot of energy and thus constantly challenge plant performance. The prob-lem of elite lines with high yield in commercial crops is often compromised stress resistance due to intensive breeding. …
“In 2009, cosmic ray intensities have increased 19% beyond anything we've seen in the past 50 years,” says Richard Mewaldt of Caltech. “The increase is…
