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…
The present development is a device that allows an incubation for specific areas, particularly for each individual vessel, providing these light/dark conditions and at the same time the implementation of optical measurements without interacting with experimental conditions in other areas
A bright supernova discovered only six weeks ago in a nearby galaxy is provoking new questions about the exploding stars that scientists use as their main…
At a distance of approximately 11.5 million light-years from Earth it is the closest supernova of its type discovered in the past few decades. The explosion…
A Chinese-U.S. research team is exploring the use of metamaterials — artificial materials engineered to have exotic properties not found in nature — to…
According to estimates of the German Federal Statistical Office about 23 million people in Germany will be 65 or older in 2050. That corresponds to 33 percent…
This year again people are suffering from severe natural disasters. Where tidal waves, earthquakes or severe storms wreak havoc in towns, villages and…
pH-biosensors based on compounds with pH-sensitive enolic groups for magnetic resonance imaging and spectroscopy and their uses. Possible medical applications for pH imaging with this new pH sensor are extremely numerous since many pathologies cause changes in pH. Good examples are tumors, inflammation and ischemia. Furthermore, the application as a very precise pH sensor for in vitro NMR-spectroscopy is possible, e.g. for response-to-treatment monitoring of treatments applied to cell lines.
The Department of Industrial and Systems Engineering (ISE) of PolyU and Sino Parking are jointly undertaking a project, entitled “Development and…
An intense light pulse interacting with a weakly bound van der Waals cluster consisting of thousands of atoms can eventually lead to the explosion of the…
However, these particletight covers are also an important hygiene precaution anywhere where bed occupancy changes regularly. Greater use of special pillow…
The giant explosions, called hot flow anomalies, can be so large at Venus that they’re bigger than the entire planet and they can happen multiple times a day.”Not only are they gigantic,” said Glyn Collinson, a space scientist at NASA’s Goddard Space Flight Center in Greenbelt, Md. “But as Venus doesn’t have a magnetic field to protect itself, the hot flow anomalies happen right on top of the planet. They could swallow the planet whole.”…
The technique—building an array of tiny pillars on top of a sheet of thermoelectric material—represents an entirely new way of attacking a century-old problem,…
In a paper published this week in the journal Physical Review Letters, MIT researchers propose an experiment that may close the last major loophole of Bell's…
Using NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) — a high-energy X-ray observatory — the international collaboration created the first-ever map of…
Using data from NASA's Rossi X-ray Timing Explorer (RXTE) satellite, an international team has uncovered a dozen instances where X-ray signals from active…
Existing procedures to generate these, however, lead to results occurring more by chance in view of the number of photon pairs in one pulse. The consequences…
