During the Aug. 12 total solar eclipse over Europe, scientists aimed to study a long-standing mystery: why the sun’s outer atmosphere, the corona, is far hotter than its visible surface. Capturing the data they needed meant being in exactly the right place at the right time.

High-energy nuclear collisions recreate extreme conditions similar to those in the early universe, producing quark–gluon plasma (QGP), a hot state of matter in which quarks and gluons are no longer confined inside protons and neutrons. While large systems such as lead–lead collisions can produce matter that behaves like a fluid, collective behavior has also been observed in smaller systems.

In the hunt for one of nature’s most elusive substances—dark matter, which makes up 85% of all matter in the universe—scientists are going to extremes. Deep underground and chilled to near absolute zero, the Super Cryogenic Dark Matter Search (SuperCDMS) SNOLAB—one of the world’s most sensitive dark matter searches—has begun collecting its first scientific data.

Table tennis professionals are true masters at redirecting fast-moving projectiles. Putting a targeted spin on a serve can make the little white ball fly straight toward the edge of the table but then, at the last moment, take a sharp curve into the left corner. The physical phenomenon behind this sporting trick is known as the Magnus effect. It acts on balls of all sizes and has helped decide more than a few soccer matches.

Lights blink on as I enter the Rover Operations Center at NASA’s Jet Propulsion Laboratory in Pasadena, California, at 7:30 a.m. I’m the first to arrive, even though I already feel late.

The latest Swedish-led search for technosignatures in the form of Dyson spheres has again come up empty-handed. The two latest stellar candidates in the hunt for such hypothetical extraterrestrial technology have been eliminated as Dyson spheres.

Venus appears pale yellow in visible light, but ultraviolet images reveal dramatic dark and bright patterns moving with the planet’s upper sulfuric acid clouds. Scientists have known about these markings for roughly a century, yet the chemical identity of the material responsible—the “unknown absorber”—remains unresolved.

As space missions become longer and ambitions for deep-space travel grow, scientists are working to understand how life beyond Earth may affect every system in the human body. Two years after her initial study took flight, Begum Mathyk, MD, and collaborators are continuing to push the frontier of women’s health in space, this time by examining how altered gravity may affect female biology.

When engineers look to nature for inspiration, they often turn to living systems. The flight of birds has influenced aircraft design, gecko feet inspired new adhesives and lotus leaves led to the development of self-cleaning surfaces.

Physics is most readily applied to relatively simple systems: a pendulum, two electrons colliding or the structure of the solar system. But when systems become complicated—when many particles interact with one another, in condensed matter systems such as gases and fluids or in the cosmology of the early universe—simplifications can be made using a technique called classical or extended mean-field theory.

A team of researchers from the University of Bonn, Heidelberg University and the National Autonomous University of Mexico has studied the critical behavior of light particles (photons) close to a phase transition. This critical scaling behavior, which sees thermodynamic quantities grow extremely large or diverge shortly prior to Bose-Einstein condensation, had never before been seen in photon gases until the researchers successfully secured precisely this proof.

Doubts about the standard model of cosmology are deepening after a new study identified fundamental problems in a recent analysis that defended the conventional view that the universe is currently undergoing accelerated expansion driven by dark energy.

While quantum computing could be the future, it is currently plagued by finicky hardware. To make the technology practical, researchers must demonstrate that it consistently and continuously works and performs at scale. In a new study, published in Physical Review Letters, researchers at Lawrence Livermore National Laboratory (LLNL) and the Ion Storage Group at the National Institute of Standards and Technology in Boulder, Colorado, created a robust process for entangling trapped-ion qubits. The result means better building blocks for ion-based quantum computers.
