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…
Electronic properties of materials can be directly influenced via light absorption in under a femtosecond (10-15 seconds), which is regarded as the limit of…
The extraterrestrial compounds found in meteorites resemble the active site of hydrogenases, which are enzymes that provide energy to bacteria and archaea by…
Since stars and planets form from collapsing clouds of gas and dust in space, “The diffuse ISM can be considered as the starting point for the chemical…
The rings of Uranus are invisible to all but the largest telescopes — they weren't even discovered until 1977 — but they're surprisingly bright in new heat…
People experiencing cardiac arrest will suddenly become unresponsive and either stop breathing or gasp for air, a sign known as agonal breathing. Immediate CPR…
Geospatial scientists have developed a new program to monitor street signs needing replacement or repair by tapping into Google Street View images.
Their data clearly show the existence of two planets. “The two planets resemble the inner planets of our solar system,” explains lead author Mathias…
“We call it 'intra-cavity feedback force'. The basic idea is that, depending on where the particle or cell you want to study is, the amount of laser light used…
The radio frequency spectrum, the basis for wireless telecommunications, is a finite resource that needs to be managed effectively to satisfy the demands posed…
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to…
Phase-change materials are used in the latest generation of smartphones enabling higher storage densities and energy efficiency. Data is recorded by switching…
Magnetic solids form the foundation of modern information technology. For example, these materials are ubiquitous in memories such as hard disk drives….
As the saying goes, nothing lasts forever. The laws of physics confirm this: on our planet, all processes increase entropy, thus molecular disorder. For…
