Phys.org / Astronomers map detailed structures in a giant radio fossil in the Ophiuchus cluster
Using the upgraded Giant Metrewave Radio Telescope (uGMRT), astronomers have performed radio observations of the Ophiuchus galaxy cluster. Results of the observations, published August 26 in The Astrophysical Journal, deliver ...
Phys.org / New isolated early-type dwarf galaxy discovered
Astronomers from Yonsei University in Seoul, South Korea, and elsewhere report the discovery of a new isolated early-type dwarf galaxy, which appears to have run away from the group environment. The finding is detailed in ...
Phys.org / Cooling pollen sunscreen can block UV rays without harming corals
Materials scientists from Nanyang Technological University, Singapore (NTU Singapore) have invented the world's first pollen-based sunscreen derived from Camellia flowers.
Phys.org / Gold-enhanced TiO₂ catalyst enables efficient and selective flow synthesis of propane from methane
Methane (CH₄), the colorless and odorless gas that makes up most natural gas on Earth, has so far been converted into useful fuels and chemicals via energy-intensive processes that need to be carried out at high temperatures. ...
Phys.org / Fast-growing brains may explain how humans—and marmosets—learn to talk
When a baby babbles and their parents respond, these back-and-forth exchanges are more than adorable-if-incoherent chatter—they help to build a baby's emerging language skills.
Phys.org / Why we slip on ice: Physicists challenge centuries-old assumptions
For over a hundred years, schoolchildren around the world have learned that ice melts when pressure and friction are applied. When you step out onto an icy pavement in winter, you can slip up because of the pressure exerted ...
Phys.org / A 'ghost' of the Australian bush: Newly discovered marsupial species may already be extinct
A new species of a native bushland marsupial—closely related to the kangaroo—has been discovered but is already likely extinct, new research shows.
Phys.org / 'Ghost sharks' grow forehead teeth to help them have sex, study suggests
Male "ghost sharks"—eerie deep-sea fish known as chimaeras that are related to sharks and rays—have a strange rod jutting from their foreheads, studded with sharp, retractable teeth. New research appearing in Proceedings ...
Phys.org / Shaky cameras can make for sharper shots, new research shows
It doesn't take an expert photographer to know that the steadier the camera, the sharper the shot. But that conventional wisdom isn't always true, according to new research led by Brown University engineers.
Phys.org / Discovery of 9,000-year-old hunter-gatherer tools in Senegal sheds light on African prehistory
What do we know about the last hunter-gatherers who lived in West Africa? While these prehistoric populations have been extensively studied in Europe and Asia, their presence in this vast region—covering 6 million square ...
Phys.org / A twist in spintronics: Chiral magnetic nanohelices control spins at room temperature
Spintronics, or spin-electronics, is a revolutionary approach to information processing that utilizes the intrinsic angular momentum (spin) of electrons, rather than solely relying on electric charge flow. This technology ...
Phys.org / No radio astronomy needed: Ring laser measures Earth's axis wobble with unprecedented precision
As Earth moves through space, it wobbles slightly. A team of researchers from the Technical University of Munich (TUM) and the University of Bonn has now succeeded in measuring these fluctuations in Earth's axis using a completely ...
