Eventually everything will evaporate, not only black holes
Eventually everything will evaporate, not only black holes
New theoretical research by Michael Wondrak, Walter van Suijlekom and Heino Falcke of Radboud University has shown that Stephen Hawking was right about black holes, although not completely. Due to Hawking radiation, black holes will eventually evaporate, but the event horizon is not as crucial as has been believed.

With light into the nanoworld
With light into the nanoworld
How optical microscopes allow detailed investigations of nanoparticles for biosensing It sounds like trying to scan a record with a hammer: light is actually too "coarse" to image small particles on the nanometer scale. However, in their project "SuperCol"- funded by the European scientists want to achieve just that: investigate nanoparticles with light.

Actively reducing noise by ionizing air
Actively reducing noise by ionizing air
Scientists show that a thin layer of plasma, created by ionizing air, could be promising as an active sound absorber, with applications in noise control and room acoustics. Did you know that wires can be used to ionize air to make a loudspeaker? Simply put, it's possible to generate sound by creating an electric field in a set of parallel wires, aka a plasma transducer, strong enough to ionize the air particles.

Canadian NIRISS instrument on Webb Maps an Ultra-Hot Jupiter's Atmosphere
Canadian NIRISS instrument on Webb Maps an Ultra-Hot Jupiter’s Atmosphere
Using the Canadian NIRISS instrument on the James Webb Space Telescope, astrophysics PhD candidate Louis-Philippe Coulombe has mapped the atmosphere of the intriguing exoplanet WASP-18 b. There's an intriguing exoplanet out there - 400 light-years out there - that is so tantalising that astronomers have been studying it since its discovery in 2009.

An algorithm for sharper protein films
Proteins are biological molecules that perform almost all biochemical tasks in all forms of life. In doing so, the tiny structures perform ultra-fast movements. In order to investigate these dynamic processes more precisely than before, researchers have developed a new algorithm that can be used to evaluate measurements at X-ray free-electron lasers such as the SwissFEL more efficiently.

Breaking the ice over a 40-year problem of supercooled water
Researchers at EPFL have found a way to study water in "no man's land," a subzero temperature range where water crystallizes rapidly. Historically, the inability to access "no man's land" has prevented researchers from unriddling the anomalous nature of water, but the breakthrough method can now change that.

Let information flow faster - with light instead of electricity
Let information flow faster - with light instead of electricity
Either 1 or 0. Either current flows or it does not. In electronics, everything is controlled via the binary system. Electrons already generate information quite fast and well, pass them on and take over various switching functions. But it can be done even faster. Paul Herrmann and Sebastian Klimmer from the Friedrich Schiller University of Jena have proven that.

Emergence of solvated dielectrons observed for the first time
Team in conjunction with the University of Freiburg generates low-energy electrons using ultraviolet light Solvated dielectrons are the subject of many hypotheses among scientists, but have never been directly observed. They are described as a pair of electrons that is dissolved in liquids such as water or liquid ammonia.

TU Graz researchers revolutionise production of biocompatible microfibres
By Falko Schoklitsch Using a newly developed method for the efficient and cost-effective production of biocompatible microfibres, the production of autologous skin and organs can be significantly accelerated. In biomedical technology, tissue engineering for the ex-vivo production of skin or organs is becoming increasingly important.

Scepticism about Microsoft results
Scepticism about Microsoft results
In March 2022, Microsoft published research results about the realisation of a special type of particle that might be used to make particularly robust quantum bits. Researchers at the University of Basel are now calling these results about so-called Majorana particles into doubt: through calculations they have shown that the findings can also be explained differently.

Bird brains can flick switch to perceive Earth’s magnetic field  
Understanding how animals make their way around in the world helps determine things humans are doing that might influence them Earth's magnetic field, generated by the flow of molten iron in the planet's inner core, extends out into space and protects us from cosmic radiation emitted by the Sun. It is also, remarkably, used by animals like salmon, sea turtles and migratory birds for navigation.

Physicists to Listen Closely to Black Holes Ring
Albert Einstein's general theory of relativity describes how the fabric of space and time, or spacetime, is curved in response to mass. Our sun, for example, warps space around us such that planet Earth rolls around the sun like a marble tossed into a funnel (Earth does not fall into the sun due to the Earth's sideways momentum).

Watching Molecules Relax in Real Time
Designing the next generation of efficient energy conversion devices for powering our electronics and heating our homes requires a detailed understanding of how molecules move and vibrate while undergoing light-induced chemical reactions. Researchers at the Department of Energy's Lawrence Berkeley National Laboratory ÜBerkeley Lab) have now visualized the distortions of chemical bonds in a methane molecule after it absorbs light, loses an electron, and then relaxes.

By adjusting knob to the quantum solid
Quantum physicists at the University of Innsbruck, together with colleagues at the ETH Lausanne, have found a new way to generate a crystalline structure that emerges as a "coherent matter density wave" in an atomic gas. The findings help to better understand the fascinating behavior of quantum matter near absolute zero.
