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…
Earlier this year, Dr. Yossi Oren and his team of researchers in the BGU Department of Software and Information Systems Engineering (ISE), discovered a…
Turbulence is everywhere- from tea cups to tokomaks and from water jets to weather systems, it is something we all see and experience. Yet, even after…
By measuring the random jiggling motion of electrons in a resistor, researchers at the National Institute of Standards and Technology (NIST) have contributed…
Think about the last time you were at a lake, river, or the ocean. Remember the ripples of the water, the waves crashing against the rocks, the wake following…
Engineers at Caltech have for the first time developed a light detector that combines two disparate technologies — nanophotonics, which manipulates light at…
Shortly after lasers were first developed in the 1960s, LiDAR — whose name originated as a combination of “light” and “radar” — capitalized on the newly…
If confirmed, this is the first duo of black holes ever shown to be moving in relation to each other. It is also, potentially, the smallest ever recorded…
Entangled states of light allow for enhanced sensitivity in optical interferometry, a measurement technique in physics. Therefore, so-called path-entangled…
“In many ways, the photoacoustic effect is already the most practical method available for detecting pollutants in the atmosphere,” said Gerald Diebold, a…
Conventional photoelectron spectroscopy can only measure samples under high vacuum, while many catalytic reactions occur under atmospheric pressure. The…
3D printers have been around since the 1980s, but we are still far from maximizing their potential. One active area of research and development is…
Being able to both walk and take flight is typical in nature – many birds, insects, and other animals can do both. If we could program robots with similar…
Modulating the amplitude and phase of light is a key ingredient for many of applications such as wavefront shaping, transformation optics, phased arrays,…
Biomedical engineers have built simple machines out of DNA, consisting of arrays whose units switch reversibly between two different shapes.
Assistant Professor Taichi Goto at Toyohashi University of Technology elucidated the noise generation mechanism of the spin wave (SW), the wave of a magnetic…
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously…
