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…
Inspired by the large droplets that form on a leaf tip or other thin filament, a team of researchers from Utah State University, University of Liège, Belgium,…
Unlike conventional metals, metallic glasses have a disordered atomic structure. This disorder is central to their behavior and enhances their properties with…
Black holes weighing as much as several billion times the mass of our Sun are found at the centres of all massive galaxies. It has been known for long that…

In 1996, when a computer won a match against the then reigning world chess champion Garry Kasparov, it was nothing short of a sensation. After this…
Carnegie Mellon University computer scientists have developed a system that can translate a wide variety of 3-D shapes into stitch-by-stitch instructions that…
Optoelectronic engineers in China and Hong Kong have manufactured a special type of liquid crystal display (LCD) that is paper-thin, flexible, light and tough….
Only by increasing the rate at which telescopes monitor the sky has it been possible to catch more Fast-Evolving Luminous Transients (FELTs) and begin to…
“Finding a galaxy without dark matter is unexpected because this invisible, mysterious substance is the most dominant aspect of any galaxy,” said lead author…
In the latest experiment of its kind, researchers have captured the most compelling evidence to date that unusual particles lurk inside a special kind of…
The idea that events occur one after the other in a fixed causal order is part of our intuitive picture of the physical world. Imagine that Alice can send a…
Quantum information is considered fragile because it can be lost when the system in which it is encoded interacts with its environment, a process called…
The device opens the door to invisible displays on walls and windows – displays that would be bright when turned on but see-through when turned off — or in…
This accomplishment is critical to developing and proposing a much larger future experiment–with approximately a ton of detectors–to study the nature of…
