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 resolution of conventional optical microscopy is limited by the fundamental physical principle of diffraction to about one half of the wavelength of the…
The team, led by CU Boulder Associate Professor Brian Hynek, braved second-degree burns, sulfuric acid fumes and the threat of eruptions to collect samples of…
Now, physicists at Chalmers University of Technology, Sweden, have discovered a new way to study these spectacular space plasma phenomena in a laboratory…
When people sweat, they unknowingly release a wide range of chemicals that can noninvasively inform clinicians on anything from stress hormone levels to…
The magneto-resistance effect is the tendency of a material to change the value of its electrical resistance in an externally-applied magnetic field. It has…
How precisely can we predict the results of measurements on a physical system? In the world of tiny particles, which is governed by the laws of quantum…
In a groundbreaking new study, researchers at the University of Minnesota used a customized, low-cost 3D printer to print electronics on a real hand for the…
Physicists distinguish between the size ranges of individual atoms and bulk matter. Between these, there are also so-called clusters, particles that can be…
Already our Greek forebearers thought about questions that still move human beings today (especially in physics), namely what is it that fundamentally holds…
Researchers at Carnegie Mellon University have used an inexpensive 3-D printer to produce flat plastic items that, when heated, fold themselves into…
In 2005 MIPT alumni Andre Geim and Konstantin Novoselov experimentally studied the behavior of electrons in graphene, a flat honeycomb lattice of carbon atoms….
Cardiac arrhythmia results when the usual symphony of electric pulses that keep the heart's muscles in sync becomes chaotic. Although symptoms are often barely…
The next generation of energy-efficient power electronics, high-frequency communication systems, and solid-state lighting rely on materials known as wide…
Walls are what they are — big, dull dividers. With a few applications of conductive paint and some electronics, however, walls can become smart infrastructure…
