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 likes to say exactly how much they weigh. Rare atomic nuclei are similarly coy, obviously not because of their own volition, but rather because they are…
“Fermi's Large Area Telescope is a state-of-the-art gamma-ray detector, but it's also a terrific tool for investigating the high-energy electrons in cosmic…
Working with computational models, the team has found that the electrons in a thin layer of vanadium dioxide sandwiched between insulating sheets of titanium…
At a German University a manufacturing technique suitably for membrane electrodes was developed. The main advantage is the usage of less platinum (up to 30%),…
Our scientific studies of biological samples derived from CRPS patients demonstrated for the first time that the onset of CRPS is caused by autoantibodies…
Scientific research concerning the pathogenesis of pityriasis at the University of Giessen demonstrated that the disease-initiating event in pityriasis is the…
With respect to both structure and function, the pro-inflammatory cytokine macrophage migration inhibitory factor (MIF) is a unique mediator of the immune…
Science and engineering are advancing rapidly in part due to ever more powerful computer simulations, yet the most advanced supercomputers require programming…
Super-sensitive microwave detectors, built at the National Institute of Standards and Technology (NIST), may soon help scientists find out.The new sensors,…
Named RAPHaEL (Robotic Air Powered Hand with Elastic Ligaments), the fully articulated robotic hand is powered by a compressor air tank at 60 psi and a novel…
Earlier this month, members of Michigan Health Engineered for All Lives, or M-HEAL, sent their prototype lamp to Uganda where it will undergo testing.”The…
Carbon nanotubes are long thin cylinders composed entirely of carbon atoms. While their diameters are in the nanometer range (1-10), they can be very long, up…
Spanish and U.S. physicists studying nanoelectronics have found that size really does matter when it comes to predicting the behavior of electrical contacts…
