Future quantum computing will require correlations between distant modules—a feature known as distributed entanglement. Traditionally, such entanglement has relied on active control and repeated measurements. Now, physicists at the Institute of Science and Technology Austria (ISTA) have realized a fully autonomous method for distributed entanglement using a “quantum bath” of correlated light particles. Published in Physical Review X, their work experimentally confirms a 20-year-old prediction and could provide a new platform for applied quantum technologies.

When neutron stars merge, they create a powerful explosion called a kilonova that flings out neutron-rich material, some of which decays into heavy elements through a process called the r-process. Recent observations of kilonovae revealed unexpected signatures that could not be explained by existing models.

This summer, Subaru Telescope will welcome a new near-infrared spectrograph, NINJA, for its first on-sky engineering observations. NINJA is a new spectrograph designed for time-critical observations of rapidly evolving cosmic events, such as the electromagnetic counterparts of gravitational-wave sources.

The properties of ultrathin magnets can be specifically altered by a slight twist between two atomic monolayers. This is the conclusion reached by an international research team led by TU Darmstadt in a study published in Nature Communications. The findings open new prospects for future memory devices.

Researchers at City College of New York physicist Vinod M. Menon’s Laboratory for Nano and Micro Photonics (LaNMP) have outlined an emerging frontier in quantum materials: atomically thin systems in which light, magnetism and electric charge are strongly intertwined. This rapidly evolving field could enable next-generation optoelectronic and quantum technologies leveraging the coupled dynamics of light, charge and spin.

The expense of launching cargo into space will plummet over the next few years, with the cost of reaching orbit forecast to more than halve between now and the end of the decade, and fall by around 93% by 2040, according to new Cambridge-led research.

More than a century after Albert Einstein first transformed our understanding of gravity, his general theory of relativity continues to withstand ever more demanding experimental tests. Now, an international team led by Ignazio Ciufolini at the Chinese Academy of Sciences has carried out the most precise measurement yet of one of the theory’s most subtle predictions: the dragging of spacetime caused by Earth’s rotation.

After decades of analyzing reams of lunar rocks back here on Earth, the canonical view of the moon was that it was anhydrous; that it had extraordinarily little water. That all began to change in 2009 with new data from NASA’s Lunar Crater Observation and Sensing Satellite (LCROSS) and the much-ballyhooed evidence of water ice in the moon’s permanently shaded polar regions (PSRs).

Researchers at the University of Warwick and the University of Colorado Boulder have directly observed, for the first time, four white dwarfs in binary star systems in our nearby region of space. These stellar binaries are all within 65 light-years of Earth, and one contains the ninth-closest white dwarf to the sun.

Scientists have detected evidence of landslides on Pluto for the first time. A paper published in the journal Icarus reports that images taken by the New Horizons spacecraft during a flyby revealed six large landslides in three impact craters.

Each summer, lawns are marked by a familiar addition: “silly sprinklers,” whose loops and spirals spew water in creative ways. While seemingly frivolous in their construction, a team of mathematicians has used their design to address a long-standing mystery surrounding the laws of physics.

Researchers have designed and built the first 3D device that can make objects invisible to heat, an advance that could transform how we protect sensitive electronics, manage heat in microchips and shield equipment from thermal detection.

CANISIUS is the official name of the new spin-echo neutron interferometer developed at Atominstitut, TU Wien. It enables precise control of neutron waves, something that was previously impossible.

The planets that appear most common in the universe could have a lot of water—but it could be hiding where telescopes can’t detect it, according to a new study led by scientists with the University of Chicago.
