Euclid finds thousands of new galaxies
Euclid finds thousands of new galaxies
Launched last year, ESA's Euclid space telescope has already been delivering data for almost a year. The first scientific results are being published today. They show that the new instrument is capable of detecting a representative sample of all galaxies in the universe. For example, a study led by the University of Innsbruck was able to identify over 600 previously unknown dwarf galaxies in the Perseus galaxy cluster .

Turning up the heat on next-generation semiconductors
Research sheds light on the properties of novel materials that could be used in electronics operating in extremely hot environments. The scorching surface of Venus, where temperatures can climb to 480 degrees Celsius (hot enough to melt lead), is an inhospitable place for humans and machines alike. One reason scientists have not yet been able to send a rover to the planet's surface is because silicon-based electronics can't operate in such extreme temperatures for an extended period of time.

Gamma-ray method monitors nuclear reactors safely and quickly
Scientists at EPFL have devised and tested out a new, gamma-noise method for monitoring nuclear reactors non-invasively and from a distance. The new method, tested out on EPFL's CROCUS nuclear reactor, can improve nuclear safety and treaty compliance. Monitoring nuclear reactors around the world to ensure that they comply with international treaties is essential for safety.

Using wobbling stellar material, astronomers measure the spin of a supermassive black hole for the first time
Using wobbling stellar material, astronomers measure the spin of a supermassive black hole for the first time
The results offer a new way to probe supermassive black holes and their evolution across the universe. Astronomers at MIT, NASA, and elsewhere have a new way to measure how fast a black hole spins, by using the wobbly aftermath from its stellar feasting. The method takes advantage of a black hole tidal disruption event - a blazingly bright moment when a black hole exerts tides on a passing star and rips it to shreds.

The origin of the sun's magnetic field could lie close to its surface
The origin of the sun’s magnetic field could lie close to its surface
Sunspots and flares could be a product of a shallow magnetic field, according to surprising new findings that may help scientists predict space weather. The sun's surface is a brilliant display of sunspots and flares driven by the solar magnetic field, which is internally generated through a process called dynamo action.

U-M study: Using ’tweezers’ to control active fluids
University of Michigan physicists have devised a way to manipulate active fluids, a type of fluid composed of individual units that can propel themselves independently, by taking advantage of topological defects in the fluids. The researchers showed that they could use tweezers similar to optical tweezers-highly focused lasers that can be used to nudge around atoms and other microscopic and submicroscopic materials-to manipulate the fluids' topological defects and control how these active fluids flow.

Scientists make quantum breakthrough in 2D materials
Scientists have discovered that a 'single atomic defect' in a layered 2D material can hold onto quantum information for microseconds at room temperature, underscoring the potential of 2D materials in advancing quantum technologies. The defect, found by researchers from the Universities of Manchester and Cambridge using a thin material called Hexagonal Boron Nitride (hBN) , demonstrates spin coherence-a property where an electronic spin can retain quantum information- under ambient conditions.

Generative AI to answer complex questions in physics
A new technique that can automatically classify phases of physical systems could help scientists investigate novel materials. When water freezes, it transitions from a liquid phase to a solid phase, resulting in a drastic change in properties like density and volume. Phase transitions in water are so common most of us probably don't even think about them, but phase transitions in novel materials or complex physical systems are an important area of study.
