Phys.org / In search of a room-temperature superconductor, scientists present a research agenda
The search for materials that can conduct electricity at room temperature without losing energy is one of the greatest and most consequential challenges of modern physics: loss-free power transmission, more efficient motors ...
Phys.org / Gravitational waves reveal hidden structure of galactic centers
A new study published in Nature Astronomy indicates that the dense, star- and dark-matter–rich environments around supermassive black hole binaries pack on the order of a million solar masses into each cubic parsec. The ...
Phys.org / Scalable quantum batteries can charge faster than their classical counterparts
Over the past decades, energy engineers have developed increasingly advanced battery technologies that can store more energy, charge faster and maintain their performance for longer. In recent years, some researchers have ...
Phys.org / Astronomers capture birth of a magnetar, confirming link to some of universe's brightest exploding stars
Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the cosmos. The finding ...
Medical Xpress / Large-scale study challenges link between acetaminophen use during pregnancy and autism risk in children
A team of Taiwanese researchers have used a nationwide, population-based cohort to examine whether taking acetaminophen during pregnancy might be linked to a higher likelihood of attention-deficit/hyperactivity disorder ...
Phys.org / Oval orbit casts new light on black hole–neutron star mergers
Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together but orbiting in an oval path rather than a perfect circle just before they merged. This discovery challenges long-standing ...
Phys.org / Ancient Filipino skeleton reveals a rare hip condition further complicated by scurvy
The growing paleopathological literature shows that scurvy was not a rare problem among people living in the ancient Asia-Pacific tropics. Scurvy is increasingly identified throughout the region, primarily in children but ...
Phys.org / 'Superconducting dome' hints at high-temperature superconductivity in thin nickelate films
Superconductivity is a quantum state of matter characterized by an electrical resistance of zero and the expulsion of magnetic fields at low temperatures below a critical point. Superconductors, materials in which this state ...
Phys.org / Carbon emissions now more than double the planetary boundary, analysis finds
Earth is not infinite. Pollution beyond certain levels threatens the climate and ecosystems. To prevent this, scientists have proposed planetary boundaries, defining the safe operating limits of the Earth system. A KAIST ...
Phys.org / Queen bees survive winter flooding by breathing underwater
Hibernation is a risky endeavor for many animals, as they can be taken away by the elements or predators. For several months of the year, queen bumblebees enter a dormant state underground called diapause. While this keeps ...
Phys.org / Galaxy-group motion suggests slower expansion in our cosmic neighborhood
Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that analyzes the motion of two nearby galaxy groups within their surrounding cosmic flow. The results ...
Phys.org / Nocturnal ants use lunar compass and sophisticated calculations to travel at night
It's well known that many animals, including migratory birds, butterflies, and even fish, use the sun for navigational purposes. Nocturnal animals are dealt a more difficult hand, however, as the moon's path is far more variable. ...
