A new generation of specialty optical fibers has been developed by physicists to cope with the challenges of data transfer expected to arise in the future age of quantum computing.

Scientists have created the first-ever atomic movies showing how atoms rearrange locally within a quantum material as it transitions from an insulator to a metal. With the help of these movies, the researchers discovered a new material phase that settles a years-long scientific debate and could facilitate the design of new transitioning materials with commercial applications.

The key to developing quantum electronics may have a few kinks. According to researchers, that's not a bad thing when it comes to the precise control needed to fabricate and operate such devices, including advanced sensors and lasers. The researchers fabricated a switch to turn on and off the presence of kink states, which are electrical conduction pathways at the edge of semiconducting materials.

In a scientific breakthrough, an international research team has developed a quantum sensor capable of detecting minute magnetic fields at the atomic length scale. This pioneering work realizes a long-held dream of scientists: an MRI-like tool for quantum materials.

Using two optically trapped glass nanoparticles, researchers observed a novel collective Non-Hermitian and nonlinear dynamic driven by nonreciprocal interactions. This contribution expands traditional optical levitation with tweezer arrays by incorporating the so called non-conservative interactions.

Researchers have developed somersaulting spin qubits for universal quantum logic. This achievement may enable efficient control of large semiconductor qubit arrays. The research group recently published their demonstration of hopping spins and somersaulting spins.

Astronomers have untangled a messy collision between two massive clusters of galaxies in which the clusters' vast clouds of dark matter have decoupled from the so-called normal matter.

Using the James Webb Space Telescope (JWST), astronomers imaged a new exoplanet that orbits a star in the nearby triple system Epsilon Indi. The planet is a cold super-Jupiter exhibiting a temperature of around 0 degrees Celsius and a wide orbit comparable to that of Neptune around the Sun. This measurement was only possible thanks to JWST's unprecedented imaging capabilities in the thermal infrared. It exemplifies the potential of finding many more such planets similar to Jupiter in mass, temperature, and orbit. Studying them will improve our knowledge of how gas giants form and evolve in time.

A new study shows that over half of the medicines stocked in space -- staples such as pain relievers, antibiotics, allergy medicines, and sleep aids -- would expire before astronauts could return to Earth.

Researchers have found a link between some of the largest and smallest objects in the cosmos: supermassive black holes and dark matter particles. Their new calculations reveal that pairs of supermassive black holes (SMBHs) can merge into a single larger black hole because of previously overlooked behavior of dark matter particles, proposing a solution to the longstanding 'final parsec problem' in astronomy.

Europa and Enceladus, icy moons of Jupiter and Saturn respectively, have evidence of oceans beneath their crusts. A NASA experiment suggests -- if these oceans support life -- signatures of that life in the form of organic molecules (like amino acids and nucleic acids) could survive just under the surface ice despite the harsh, ionizing radiation on these worlds. If robotic landers were to go to these moons to look for life signs, they would not have to dig very deep to find amino acids that have survived being altered or destroyed by radiation.

So far, only about ten intermediate-mass black holes have been discovered in the entire universe. The newly identified black hole causes surrounding stars in a cluster to move in an unexpectedly orderly way.

In an era when the creation of artificial intelligence (AI) images is at the fingertips of the masses, the ability to detect fake pictures -- particularly deepfakes of people -- is becoming increasingly important. So what if you could tell just by looking into someone's eyes? That's the compelling finding of new research which suggests that AI-generated fakes can be spotted by analyzing human eyes in the same way that astronomers study pictures of galaxies.

An international team of physicists has proven new theorems in quantum mechanics that describe the 'energy landscapes' of collections of quantum particles. Their work addresses decades-old questions, opening up new routes to make computer simulation of materials much more accurate. This, in turn, may help scientists design a suite of materials that could revolutionize green technologies.

The newly discovered planet TIC 241249530 b has the most highly elliptical, or eccentric, orbit of any known planet. It appears to be a juvenile planet that is in the midst of becoming a hot Jupiter, and its orbit is providing some answers to how such large, scorching planets evolve.

Researchers have demonstrated that the layered multiferroic material nickel iodide (NiI2) may be the best candidate yet for devices such as magnetic computer memory that are extremely fast and compact. Specifically, they found that NiI2 has greater magnetoelectric coupling than any known material of its kind.

Tantalizing evidence of potential dark matter objects has been detected with the help of the Universe's 'timekeepers'. These pulsars -- neutron stars which rotate and emit lighthouse-like beams of radio waves that rapidly sweep through space -- were used to identify mysterious hidden masses. Pulsars earned their nickname because they send out electromagnetic radiation at very regular intervals, ranging from milliseconds to seconds, making them extremely accurate timekeepers.

Astronomers have uncovered what appear to be 21 neutron stars in orbit around stars like our Sun. The discovery is surprising because it is not clear how a star that exploded winds up next to a star like our Sun.

A new study on common food aromas may help explain why astronauts report that meals taste bland in space and struggle to eat their normal nutritional intake. This research has broader implications for improving the diets of isolated people, including nursing home residents, by personalizing aromas to enhance the flavor of their food.

A new study of radar experiment data from the Cassini-Huygens mission to Saturn has yielded fresh insights related to the makeup and activity of the liquid hydrocarbon seas near the north pole of Titan, the largest of Saturn's 146 known moons.
