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 novel test system can discriminate T cell immunity induced by an acute encounter of influenza viruses from lasting T cell immunity after earlier infections…
Autoantibodies to progranulin in samples from subjects suffering from ANCA-associated and ANCA-negative primary systemic vasculitides as well as in other…
Most people know about ultrasound through its role in prenatal imaging: those grainy, grey outlines of junior constructed from reflected sound waves. A new…
This exoplanet, known as Kepler-78b, orbits its star very closely every 8.5 hours, making it much too hot to support life. The results are being published in…
Ben Mazin, assistant professor of physics at UC Santa Barbara, has developed a superconducting detector array that measures the energy of individual photons….
Heart failure is the main cause of death throughout the world. Classical pharmacological treatment may halt, but cannot reverse the underlying disease process….
Transmission losses and background noise can considerably impair speech intelligibility when making calls on a cell phone – particularly for people who suffer…
The scientists have actively stabilized the wavelength of the photons emitted by a semiconductor thereby neutralizing the charge noise in the semiconductor….
A new class of materials developed at the University of Arkansas may influence the next generation of nano-devices, in which integrated circuits are composed…
The researchers discovered, as they show in the journal Nature Photonics, that it is possible to distinguish aggregations of the proteins, believed to cause…
Astronomers at The Ohio State University have calculated the odds that, sometime during the next 50 years, a supernova occurring in our home galaxy will be…
