How to enjoy the solar eclipse safely

Most people underestimate how much light a pair of sunglasses blocks out. A typical dark pair removes around 80% to 90% of the visible light reaching the eye.

Spontaneous magnons synchronize with external signals at room temperature

Signals ride on waves of one kind or another: light, sound, radio. But new carriers are needed to relay information in next-generation devices. Disturbances or waves in magnetic materials called magnons could be an efficient option—if scientists can tame them.

Mirage or miracle? JWST finds earliest known ‘black hole star’ at cosmic dawn

Little red dots have puzzled astronomers since their discovery in James Webb Space Telescope (JWST) data from the universe’s deep past. Their “powering engines” might resemble a newly discovered phenomenon dubbed a “black hole star”—an early, rapidly growing black hole wrapped in dense gas. This object, described in a study published today in Nature by researchers at the Institute of Science and Technology Austria (ISTA) and international collaborators, may help explain how billion-solar-mass black holes formed so soon after the Big Bang.

Three supermassive black holes discovered in a single galaxy for the first time

An international team of astronomers led by the Max Planck Institute for Extraterrestrial Physics has identified three actively accreting supermassive black holes in the galaxy J0148-4214. Matter is falling into the black holes from accretion disks surrounding them.

Quantum advantage reassessed: More realistic benchmarks for quantum algorithms

Quantum advantage refers to the point at which a quantum computer solves a clearly defined task faster or more efficiently than any classical computer—or makes it solvable in the first place. For many practical applications, this has not yet been demonstrated. Research therefore relies heavily on theoretical models and simulations to explore where and under what conditions such an advantage may realistically be achieved in the future.

Moonquakes could reveal buried lunar ice for future explorers

The surface of the moon is a bleak and forbidding place that could be hiding a lot of water ice within its dusty landscape. However, most possible ice deposits don’t just stand out in an image. Scientists need specialized mapping to find those deposits, so they have devised another way to find the moon’s frosty hidden reserves. They use seismic waves from moonquakes as locator beacons.

Long-sought Zhang-Rice singlet visualized directly in cuprate superconductor

Superconductors are materials that conduct electricity with zero electrical resistance below specific temperatures. Most of these materials become superconducting at very low temperatures, but some also exhibit superconductivity at higher temperatures.

How to design a space habitat that supports its residents’ mental health

In extreme environments, habitats are built for survival. Submarines, Antarctic bases and post-disaster dwellings are designed to prioritize health and safety. This is especially the case for habitats in space, where room is limited, contact with Earth is remote and hazards are numerous.

Total solar eclipse to spellbind Europe

Millions of Europeans will contemplate the sky in awe on Wednesday as a rare total solar eclipse crosses part of the continent and plunges a swath of Spain into eerie daytime darkness.

Looking to see the solar eclipse from North America? Here’s where and when to catch a sliver

Sorry, North America. After winning the cosmic lottery with a pair of coast-to-coast total solar eclipses, now it’s Europe’s turn.

The ESCAPE mission will study the evolution of exoplanet atmospheres

The habitable zone concept is useful for understanding which worlds might, possibly, maybe, be habitable. It highlights exoplanets at the right distances from their stars for liquid water to potentially exist on their surfaces. But that alone can’t determine habitability.

New CERN measurement challenges conventional models of how gluons behave inside atomic nuclei

A University of Kansas physicist played a leading role in a CERN study showing that two rival explanations for how gluons behave inside atomic nuclei can now be experimentally distinguished.

Three energy-loss routes may explain Tarantula Nebula’s X-ray shortfall

Like a collage made of layered sheets of colored cellophane, a vibrant new image layers observations of a famous star-forming nebula from NASA’s space telescopes. The resulting cosmic “craft” reveals new details about the star-forming region known as 30 Doradus, or the Tarantula Nebula.

New contactless method reveals how mirror-image materials respond differently to light

New research introduces a contactless way to see how mirror-image materials respond differently to circularly polarized light, without first building them into a complete electronic device. The researchers developed a novel method based on light-induced charge separation that allows researchers to directly probe how the material’s structure acts like a microscopic filter, influencing how electrons separate and move.
