Phys.org / How the octopus uses its 'taste by touch' sensory system to feel out potential mates
A new study by Harvard biologists reveals how octopuses feel their way to potential mates with a "taste by touch" sensory system and can even couple at arm's length without actually seeing each other. In a study featured ...
Phys.org / New disk-shaped catalyst turns carbon dioxide into methanol at lower temperatures
Low-temperature CO2 hydrogenation might have sounded almost paradoxical until a recent study made it possible. Researchers have designed new catalysts that can transform the greenhouse gas into methanol at temperatures ranging ...
Phys.org / New evidence challenges assumptions of mass feasting at ancient Mongolian burial mounds
Khirigsuurs are Late Bronze Age monuments found across Mongolia and parts of southern Siberia. They are typically thought to be burial monuments or ritual spaces, consisting of a burial mound surrounded by satellite features ...
Phys.org / New miniature marsupial frog found in Peru carries eggs in a back pouch
Scientists have discovered a new species of miniature marsupial frog in the Peruvian Amazon that carries its young in a natural pouch on its back, a research institute reported Wednesday.
Phys.org / Gravity from positivity: Single massive spin-3/2 particle makes gravity logically inevitable, study claims
Researchers at IPhT (CEA, CNRS) and the Universitat Autònoma de Barcelona have shown that gravity—and with it, supersymmetry—emerge as logical necessities whenever a massive spin-3/2 particle exists in nature. Two principles ...
Phys.org / Spectacular fossil treasure trove pushes back origins of complex animals
A newly discovered fossil site in southwest China has transformed our understanding of how complex animal life emerged on Earth, revealing that many key animal groups had already evolved before the start of the Cambrian Period. ...
Phys.org / Cosmologists collaborate to sharpen measurements of the Hubble constant
Drawing together leading experts from across the field, an international collaboration of cosmologists has created a unified approach for measuring the value of the Hubble constant. Published in Astronomy & Astrophysics, ...
Phys.org / Current connection: Scientists detail how shifts in the Atlantic Ocean impacted the Alaskan climate 13,000 years ago
Some newly published findings from an Idaho State University professor and his colleagues point out how changes to currents an ocean away can impact climates on the other side of the globe. The new paper published in Nature ...
Phys.org / Ghostly particles: Dark radiation may have masqueraded as neutrinos
New research suggests that neutrinos in the early universe may have transformed into a previously unknown form of radiation. A study from Washington University in St. Louis offers a new way to explain certain puzzling observations ...
Phys.org / How mitochondria organize our 'second genome'
EPFL scientists have discovered that a simple shape change in mitochondria helps cells evenly distribute their mitochondrial DNA, solving a long-standing puzzle.
Phys.org / Quantum entanglement between electrons and ions captured at attosecond timescale
Quantum mechanics is extremely successful at describing the behavior of matter at the atomic level. This success forces one to accept that certain aspects of physical reality go far beyond our intuition. Among these, none ...
Phys.org / Smartphone rapid test detects microbiologically contaminated water in less than a minute
Worldwide, billions of people rely on water sources whose hygienic quality is unclear or difficult to monitor. Conventional microbiological analysis methods take up to 24 hours, are costly, and require specialized laboratories ...
