Our 'Spotlight on' series highlights how our researchers are leading their field and transforming lives.

Experiments from the Caltech lab of Chiara Daraio, G. Bradford Jones Professor of Mechanical Engineering and Applied Physics and Heritage Medical Research Institute Investigator, have yielded a

An interdisciplinary research group at TU Graz is working on constructing logic circuits through the targeted arrangement of individual molecules.

In the decades following the launch of NASA's Hubble Space Telescope , astronomers have tallied over 1 trillion galaxies in the universe.

Professor Carla Figueira De Morisson Faria (UCL Physics & Astronomy) writes in The Conversation about how research into incredibly short laser pulses can have wide ranging impacts across a range of technologies.

Researchers from ETH Zurich and ZHAW Winterthur are simulating in a new study how the future Swiss power system could be structured to withstand a drastic fall in gas and electricity imports.

The advance holds the promise to reduce error-correction resource overhead. Quantum computing promises to solve complex problems exponentially faster than a classical computer, by using the principles of quantum mechanics to encode and manipulate information in quantum bits (qubits).

With their recently-developed neural network architecture, MIT researchers can wring more information out of electronic structure calculations.

An effort to find some of the biggest, most active black holes in the universe provides a better estimate for the ratio of hidden to unhidden behemoths. Multiple NASA telescopes recently helped scientists search the sky for supermassive black holes - those up to billions of times heavier than the Sun.

Their source could be the core of a dead star that's teetering at the black hole's edge, MIT astronomers report. One supermassive black hole has kept astronomers glued to their scopes for the last several years. First came a surprise disappearance, and now, a precarious spinning act. The black hole in question is 1ES 1927+654, which is about as massive as a million suns and sits in a galaxy that is 270 million light-years away.

UCLA physicist John Miao pioneered a new form of microscopy with unprecedented precision and field of view Key takeaways Computational microscopy has rapidly advanced in the last quarter-century, enabling researchers to visualize the extremely small and ultrafast by applying advanced algorithms to interpret scattering patterns of photons and electrons.

The University of Geneva coordinates the participation of Swiss institutions in the CTAO project, which addresses the most fascinating questions of high-energy astrophysics.

On November 8, astronomers at Caltech's Palomar Observatory in the mountains above San Diego directed a brand-new spectrograph instrument to capture data from a newfound supernova.

A significant research grant from the Wellcome Trust will allow a team of researchers to identify the biological mechanisms through which magnetic forces affect animals, including humans. Scientists have long known that many animals have a magnetic sense, which some use to navigate around the Earth, particularly during their spectacular seasonal migrations.

Associate Professor Matteo Bucci's research sheds new light on an ancient process, to improve the efficiency of heat transfer in many industrial systems.

Filaments curling at the micro and nanoscale produce light waves that twirl as they travel Study: Bright, circularly-polarized black-body radiation from twisted nanocarbon Filaments ( adq4068) Bright

Teeth are essential for helping people break down the food they eat, and are protected by enamel, which helps them withstand the large amount of stress they experience as people chew away.

UCLA physicists have developed a new film that requires much less of the rare thorium-229 and is significantly less radioactive Key takeaways Atomic clocks that excite the nucleus of thorium-229 embed

Survey of 26,000 dead stars confirms key details of extreme stellar behavior A study of more than 26,000 white dwarf stars has confirmed a long-predicted but elusive effect in these ultra-dense, dying stars: Hotter white dwarfs are slightly puffier than cooler ones, even when they have the same mass.

The technique provides researchers with a powerful tool for controlling magnetism, and could help in designing faster, smaller, more energy-efficient memory chips.

An electronic stacking technique could exponentially increase the number of transistors on chips, enabling more efficient AI hardware. The electronics industry is approaching a limit to the number of transistors that can be packed onto the surface of a computer chip. So, chip manufacturers are looking to build up rather than out.

Two networks of telescopes zoom into a distant galaxy: they show, how pictures of a black hole and its jets become possible - and they confirm that there are strong magnetic fields there.

VU Amsterdam closes during the holidays. Please ask your questions on time and arrange your affairs before 21 December.

The Coalition has released the costing of its nuclear energy plan - how does it compare with Labor's renewables-only energy plan?

Physicist Arthur Hendriks makes nanoparticles visible with ultra-sensitive light sensors. His grandfather and father preceded him, having stood behind the lectern at the same university as well as the same department.

The Sun should be capable of eruptions that are a hundred times stronger than the strongest flare ever recorded. This is shown by an analysis of over 50,000 sun-like stars. Stars similar to the Sun produce a gigantic outburst of radiation on average about once every hundred years per star. Such superflares release more energy than a trillion hydrogen bombs and make all previously recorded solar flares pale in comparison.

Key takeaways The galaxy M87, located in the Virgo constellation, provided the first-ever photo of a black hole in 2019, when the Event Horizon Telescope captured an image of the supermassive black hole at the galaxy's center. An international research team including UCLA has observed a teraelectronvolt gamma-ray flare seven orders of magnitude - tens of millions of times - larger than the event horizon, or surface of the black hole itself.

Researchers at the University of Waterloo's Institute for Quantum Computing (IQC) have found that quantum algorithms could speed up generative artificial intelligence (AI) creation and usage.

A cyberattack occurs every 39 seconds. This alarming statistic(*) highlights the constant threat to today's security systems.

In the future, delivering therapeutic drugs exactly where they are needed within the body could be the task of miniature robots. Not little metal humanoid or even bio-mimicking robots; think instead of tiny bubble-like spheres. Such robots would have a long and challenging list of requirements. For example, they would need to survive in bodily fluids, such as stomach acids, and be controllable, so they could be directed precisely to targeted sites.

Study: Training all-mechanical neural networks for task learning through in situ backpropagation (DOI:10.1038/s41467-024-54849-z) It's easy to think that machine learning is a completely digital phenomenon, made possible by computers and algorithms that can mimic brain-like behaviors. But the first machines were analog and now, a small but growing body of research is showing that mechanical systems are capable of learning, too.

Zooming in to the "pixels of reality": the electron microscope helps us to do that. However, it is unsuited for particularly sensitive targets.
