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…
Just two years ago, with the advent of a technique called direct measurement, scientists discovered they could reliably determine a system’s wave function by…
Raman marker as a novel labeling reagent for the selective detection of biomolecules. Their use provides three key benefits: simultaneous detection of many different target molecules, high sensitivity and quantification of the detected biomolecules
A newly developed kite system allows to alter the line length while kite surfing by around 80% of the line length. This enables new kitesurf scenarios. Due to limited shore space kitesurfer may start with short lines and bring them full length later on the water. Furthermore, while surfing, the line length can be adjusted to wind conditions. After landing, the lines can be drawn in directly avoiding winding in and tangling of leashes.
Spin-charge converters are important devices in spintronics, an electronic which is not only based on the charge of electrons but also on their spin and the…
Electronic circuits are based on electrons, but one of the most promising technologies for future quantum circuits are photonic circuits, i.e. circuits based…
When it arrived at our planet, the ring current and radiation belts surrounding Earth swelled with extra particles, while the aurora persisted for six hours….
A few months after scientists began tracking the star, called NGC 2547-ID8, it surged with a huge amount of fresh dust between August 2012 and January 2013.
Scientists from Goethe University of Frankfurt/Main synthesized novel arylborane compounds with extraordinary electronic, chemical, and optical properties. The novel blue fluorescent dyes are well suited for use in organic light emitting diodes (OLEDs).
The novel class of fluorophores with high quantum efficiencies is built around a pyrazole unit. These compounds exhibit emission maxima at around 380 nm. Additionally to high quantum efficiency and chemical resistance, the molecules provide a polar anchoring group enabling straightforward substrate attachment.
A*STAR researchers have developed an anticipatory alarm system based on dynamic models of industrial processes using concepts similar to extreme weather…
The discovery was made possible through combined observations from NASA’s Hubble and Spitzer space telescopes, the W.M. Keck Observatory in Mauna Kea, Hawaii,…
Only recently has it become possible to accurately “see” the structure of a liquid. Using X-rays and a high-tech apparatus that holds liquids without a…
The extraordinary brightness and regularity of their light curves in the visible spectral range make type Ia supernovae valuable standardizable light sources,…
Computer hard drives store data by writing magnetic information onto their surfaces. In the future, magnetic effects may also be used to improve active memory…
Astronomers have uncovered for the first time the earliest stages of a massive galaxy forming in the young Universe. The discovery was made possible through…
The star, named W49nr1, has a mass between 100 and 180 times the mass of the Sun. Only a few dozen of these very massive stars have been identified so far. As…
