Phys.org / Ctenophore research points to earlier origins of brain-like structures
New 3D reconstructions of a key sensory organ in ctenophores reveal an unexpected structural and functional complexity. The findings suggest that an elementary brain may have already appeared in our most ancient relatives, ...
Phys.org / Self-propelling microbes switch up swimming strategy to optimize light intake
Researchers in Hong Kong and the UK have revealed how one species of self-propelling microbes can actively change the path of their swimming motions, depending on how much light they receive. Reporting in Physical Review ...
Phys.org / The coldest 'stars' in the galaxy might actually be alien megastructures
Ever since physicist Freeman Dyson first proposed the concept in 1960, the "Dyson sphere" has been the holy grail of techno-signature hunters. A highly advanced civilization could build a "sphere" (or, in our more modern ...
Medical Xpress / Open-source, privacy-focused platform aims to help researchers examine how digital interactions influence health
Numerous sensors allow smartphones to silently witness everything we do, says Ian Kim, a postdoctoral fellow in psychology at Stanford University. They count each smartphone owner's steps, measure their sleep, record where ...
Medical Xpress / Researchers detect complex emotions by combining multiple optical signals
Researchers have developed a new way to recognize human emotions by combining fiber-based physiological signals with thermal images of the face. The portable emotional recognition system could eventually be used to support ...
Phys.org / Ancient plant-eater with a twisted jaw and sideways-facing teeth was a 'living fossil' in its own time
In a dry riverbed in Brazil, in a dense forest near the Amazon, a team of paleontologists found a fossilized jawbone from an ancient animal. Over the course of their fieldwork, they found eight similar bones, each around ...
Phys.org / Rewilding could fill gap left by Panama's lost giants
Many large herbivores that once roamed modern-day Panama have declined or died out—including the 6-meter-long giant ground sloth and elephant-related creatures called Cuvieronius. New research suggests that introducing ...
Phys.org / Why Large Hadron Collider predictions can miss the mark, and a new way to fix it
Estimating things that exist is generally easy, but when it comes to estimating things that do not exist, it's more difficult. This is something physicists from Poland and the UK are well aware of. To improve current simulations ...
Phys.org / From water splitting to H₂O₂: A new method narrows carbon nitride photocatalyst design
Photocatalysis promises an efficient conversion of abundant solar energy into usable chemical energy. Polyheptazine imides have some key structural and functional twists that make them especially interesting for photocatalysis. ...
Phys.org / Female astronauts face clotting risks, five-day weightlessness simulation suggests
Just a few days in simulated microgravity can subtly change the way women's blood clots, sparking bigger questions about health monitoring protocols for astronauts who can spend six months or more in orbit, say Simon Fraser ...
Phys.org / Charred pot residues reveal prehistoric Europeans' surprisingly complex cuisines
Thousands of years ago, European communities used a variety of plant and animal products to create elaborate meals, according to a study published in the open-access journal PLOS One by Lara González Carretero of the University ...
Medical Xpress / Targeting the untargetable cancer—rezatapopt, an oral p53 reactivator
Memorial Sloan Kettering Cancer Center investigators and collaborators have tested rezatapopt, an oral p53 reactivator designed for tumors with TP53 Y220C, and observed antitumor activity across multiple solid tumor types ...
