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…
Physicists around the world are searching for the best way to realize a quantum computer. Now scientists of the team around Stefan Kuhr and Immanuel Bloch at…
Fluorescent “defect centers” in diamond act like atomic-scale light sources and are trapped in a transparent material that's large enough to be picked up…
According to Wan, healthy tissues naturally secrete mucus to protect against infection. Cancer cells, however, produce far more mucus than healthy cells. Mucus…
One type of scanner employs millimeter wave technology, which delivers no ionizing radiation. However, the second type of scanner currently deployed at…
“Our theory is a long shot,” admitted Weiler, who is a physics professor at Vanderbilt University, “but it doesn’t violate any laws of physics or experimental…
“Electronic devices mostly use the charge of the electrons – a negative charge that is moving,” says Ashutosh Tiwari, an associate professor of materials…
The star-forming region NGC 6729 is part of one of the closest stellar nurseries to the Earth and hence one of the best studied. This new image from ESO's Very…
“To my knowledge, nobody had ever done systematic measurements on this equipment, since by the time one had the tools, these systems had been replaced by more…
In ferroelectric memory the direction of molecules' electrical polarization serves as a 0 or a 1 bit. An electric field is used to flip the polarization, which…
In the latest twist on optical knots, New York University (NYU) physicists have discovered a new method to create extended and knotted optical traps in three…
Scientists are excited about solving some of the mysteries surrounding our smallest and hottest planet. The findings are expected to broaden our understanding…
Although in principle quantum mechanics can describe the properties of molecules and materials in which the electrons’ motions are strongly correlated, in…
The part of the nebula visible in this image from Hubble's Advanced Camera for Surveys is criss-crossed with tendrils of dust and gas churned up by recent…
The universe appears to be expanding at an increasing rate. Some believe that is because the universe is filled with a dark energy that works in the opposite…
The idea that a rainbow of broadband light could be slowed down or stopped using plasmonic structures has only recently been predicted in theoretical studies…
