Dark matter may leave subtle color traces in passing light

October 23, 2025 Theo Klein

Researchers at the University of York suggest that dark matter could subtly tint light red or blue as it passes through, challenging the idea that it is completely invisible. This indirect interaction might allow detection using next-generation telescopes. The finding could simplify the search for the mysterious substance that dominates the universe.

Scientists uncover hidden cavities in 2D materials

Researchers have discovered that stacks of two-dimensional materials naturally form microscopic cavities that trap light and electrons, altering quantum behavior without the need for mirrors. This finding, observed using a novel terahertz spectroscope, could enable new ways to control exotic quantum states. The study was published in Nature Physics.

Researchers identify limits of quantum computers on exotic matter

Scientists have proven that even advanced quantum computers may fail to identify certain exotic quantum phases of matter, describing it as a 'nightmare scenario.' This finding highlights potential boundaries in quantum computation despite its promises. The research, led by Thomas Schuster at Caltech, connects quantum information science with physics fundamentals.

Physicists uncover rotating crystals with lifelike properties

A team of physicists has discovered unusual rotating crystals made of spinning particles that exhibit behaviors resembling living matter, such as twisting instead of stretching and self-reassembly after breaking. These materials, governed by transverse interactions, challenge conventional crystal growth rules. The findings, published in the Proceedings of the National Academy of Sciences, suggest potential applications in technology and biology.

Twin black hole mergers test Einstein's general relativity

Two black hole collisions detected in late 2024 have provided unprecedented tests of Einstein's general theory of relativity. The events, captured by the LIGO-Virgo-KAGRA Collaboration, revealed unusual spins and possible second-generation black holes. These detections confirm theoretical predictions with high precision and probe for new particles.

Physicists measure trillion-degree heat in Big Bang plasma

Researchers at Rice University have captured the temperature profile of quark-gluon plasma, the ultra-hot matter from the universe's dawn. By analyzing electron-positron emissions from atomic collisions, they determined precise temperatures at different evolutionary stages. The findings, published in Nature Communications, refine understanding of early cosmic conditions.

Early universe radio waves may reveal dark matter

Researchers at Tel Aviv University have proposed detecting faint radio waves from the cosmic dark ages to uncover dark matter's properties. These signals, emitted by hydrogen gas influenced by dark matter clumps just 100 million years after the Big Bang, could be best observed from the Moon. The findings, published in Nature Astronomy, highlight a new method to probe the Universe's earliest moments.

Chalmers researchers develop platform to study nanoscale forces

Scientists at Chalmers University of Technology in Sweden have created a simple optical platform using gold flakes in salt water to visualize quantum and electrostatic forces at the nanoscale. These forces, described as 'nature's invisible glue,' bind tiny objects and could inform advancements in biosensors, medicines, and even galaxy formation. The technique reveals interactions through colorful light patterns observed under a microscope.

A UCLA-led team has captured the most detailed image ever of a disk around the distant star beta Canis Minoris using a innovative photonic lantern on a single telescope. This breakthrough reveals hidden structures without needing multiple telescopes. The discovery uncovers a lopsided hydrogen disk 162 light-years away.

Physicists manipulate material properties with light pulses

Researchers at the University of Konstanz have developed a technique to alter the magnetic properties of materials using laser pulses, effectively transforming one material into another at room temperature. By exciting pairs of magnons in common haematite crystals, the method enables non-thermal control of magnetic states and potential data transmission at terahertz speeds. This breakthrough could allow quantum effects to be studied without extreme cooling.
