Superconductors are materials that conduct electricity with an electrical resistance of zero. Superconductivity is generally observed when materials are cooled down to extremely low temperatures. In some cases, however, like in so-called high-temperature superconductors, this property emerges at higher temperatures. Go to Source Scientists in Geneva are taking some antiprotons out for a spin—a very delicate one—in a truck, in a never-tried-before test drive. Go to Source Visible to the naked eye in the constellation Cassiopeia, the star γ Cas has puzzled astrophysicists for half a century. It emits X-rays of an intensity and temperature incompatible with what one would expect from an ordinary massive star. Observations, carried out using the Resolve instrument aboard the Japanese XRISM telescope, now allow us to […] For the last few decades, researchers have been studying what the universe looked like in its first seconds. It is generally accepted that the universe expanded exponentially in the first fraction of a second after the Big Bang. Researchers use ns, the scalar spectral index, to characterize how primordial density fluctuations were distributed across different […] Gallium nitride, a semiconductor that can operate at high voltages, temperatures, and frequencies, has enabled technologies from LED lighting to high-power electronics. Now Cornell researchers have observed a quantum property of the material for the first time, an advance that could expand its technological reach. Go to Source Stellar streams are trails of stars that astronomers can study to solve mysteries about the history of our Milky Way galaxy and, potentially, the dark matter that helps shape the cosmos despite eluding direct observation. These streams have largely been left behind by small dwarf galaxies and globular clusters, which have since petered out of […] New UNLV-led research is helping to unravel clues to a cosmic mystery that has eluded scientists for decades. Cataclysmic variables (CVs) are binary star systems in which primary stars—incredibly dense and compact white dwarfs—accumulate material from nearby companion stars. The material spirals in towards the white dwarf through what is known as an accretion disk. […] This March 16, 2026, image from NASA’s Hubble Space Telescope and the James Webb Space Telescope takes a closer look at the core of Messier 101, also known as the Pinwheel Galaxy. Go to Source Jupiter’s lightning has long been of interest to planetary scientists, as it marks stormy spots where researchers can look to learn more about convection in Jupiter’s atmosphere. Observing lightning from a distance can be tricky, so scientists have focused on the bolts that are easiest to study: strong flashes that strike at night. As a […] A tiny crystal chip which uses terahertz radiation to see clearly through a wide range of materials could find applications in health care, biological research, and security screening. Researchers from Scotland and Japan have developed a lightweight superconducting chip, which they say could unlock the full potential of terahertz imaging technologies and lead to the […] Nearly a millennium ago, astronomers witnessed a brilliant new star blazing in the sky—a supernova so bright it was visible in daylight for weeks. Today, its expanding remnant, the Crab Nebula, continues to evolve 6,500 light-years away. First linked to historical records by Edwin Hubble, the nebula has since been studied in exquisite detail by […] The Harris County Sheriff’s Office’s disciplinary committee found that Deputy Aileen Jimenez Barboza violated multiple department policies in the shooting death of Levincer Swanson Go to Source “Shots Fired” hosts broke down the lawsuit tied to a 2022 search warrant at rapper Afroman’s Ohio home, weighing search warrant tactics, privacy expectations and why the case became a viral punchline Go to Source Video from the incident shows the suspect initially surrendering to Yuba City officers before resisting, fleeing and arming himself with a shovel Go to Source Researchers report the discovery of a Saturn-sized exoplanet orbiting two M-dwarf stars, which are smaller and cooler than our sun. The findings from this discovery were published in the The Astronomical Journal and were made using a lesser-known exoplanet discovery method known as gravitational microlensing, or microlensing for short.
