Phys.org / Rare soft-bodied fossil from Quebec reveals a new jellyfish relative from 450 million years ago
Canadian researchers studying 450-million-year-old fossils near Quebec City have identified a new species of basal-medusozoan: Paleocanna tentaculum, a soft-bodied, tube-shaped polyp with a ring of tentacles. Closely related ...
Phys.org / New AI method captures long-range atomic interactions in complex molecules
Researchers from Google DeepMind in Berlin, BIFOLD, and the Technical University of Berlin have introduced a new machine learning method—Euclidean Fast Attention (EFA)—that enables global atomic interactions in chemical systems ...
Phys.org / A hidden property of light could power future nanomachines
Light does more than illuminate the world—it can also push and twist matter. It was back in the 1870s that James Clerk Maxwell first predicted that light carries momentum and can exert pressure on objects. Nearly a century ...
Phys.org / Hubble dazzles with young stars in Trifid Nebula
This shimmering region of star-formation, a close-up of the Trifid Nebula about 5,000 light-years from Earth, was captured in intricate detail by NASA's Hubble Space Telescope. The colors in Hubble's visible light image, ...
Phys.org / Cambrian microfossils reveal earliest known ringed worms from 535 million years ago
Scientists have uncovered the earliest fossil evidence of annelids (ringed worms) in Cambrian microfossils dating back approximately 535 million years ago. This discovery offers fresh insights into the origin and early evolution ...
Phys.org / Why ultrashort laser pulses could make low-power electron sources far more practical
A new theoretical study finds shorter laser pulses achieve higher quantum efficiency for photoemission from a solid surface without increasing power or intensity. Using light to knock electrons loose from a surface—known ...
Phys.org / Australia's truffle industry may owe part of its success to a surprising underground secret
Imagine ordering a truffle dish in a fancy restaurant, and you might picture pricey gourmet mushrooms from France or Italy. But recent decades have seen an upstart on the truffle scene. Today, one of the world's largest producers ...
Phys.org / Cocaine pollution alters salmon behavior in the wild, study reveals
An international study, led by researchers from Griffith University, the Swedish University of Agricultural Sciences, the Zoological Society of London and the Max Planck Institute of Animal Behavior, is the first to demonstrate ...
Phys.org / What makes Mars' magnetotail flap? Two spacecraft point to magnetic reconnection
The sun continuously blasts charged, magnetic field-carrying particles, or plasma, in all directions. This solar wind interacts with the magnetic fields and atmospheres of several of our solar system's planets and other bodies, ...
Phys.org / Why climate models and ocean observations diverge, and what it means for rain and drought
Scientific models have predicted that climate change will drive oceans in the Northern Hemisphere to warm faster than oceans in the Southern Hemisphere. However, observational data over the last 70 years show the opposite—that ...
Phys.org / Connected habitats help frogs keep protective microbes and curb deadly fungus
Maintaining connections between natural habitats may support beneficial microbes that help wildlife defend against disease. In a new study of tropical amphibians, a team led by Penn State biologists found that amphibians ...
Dialog / Sprinkling nanoparticles on spintronics
Today, I want to walk you through a deceptively simple innovation from the lab at Loughborough University (PI: Prof Marco Peccianti): what happens when we decorate a spintronic heterostructure with a sparse layer of plasmonic ...
