Phys.org / Cutting a photon in two creates an infinite swarm of particles
By definition, elementary particles can't be broken into smaller pieces. But in a new theoretical study published in Physical Review Letters, Johannes Skaar and colleagues have revealed what would happen if you tried anyway ...
Phys.org / How a Richard Feynman formula could explain your dining habits in a new city
One of the dilemmas facing anyone in a new and unfamiliar city is where to dine out. You might consult guides, speak to locals, check reviews, and ultimately, try your luck. But if you're there for a while, at some point ...
Phys.org / Britain's oldest cave art may have been rediscovered in Bacon Hole cave
The oldest cave art in Britain may have been discovered, or more likely rediscovered, in a cave on the Gower Peninsula in South Wales, possibly dating back around 17,000 years.
Phys.org / Flatworms reveal exploding immune cells that kill surrounding tissue
Stanford scientists have discovered a new type of immune cell that kills surrounding cells via explosion—a cellular detonation so fast and complete that the cell vanishes within minutes, leaving no trace behind. This discovery ...
Phys.org / Molecular glasses solve long-standing Arrhenius paradox
Glasses are non-crystalline but solid states of matter in which molecules and atoms are not arranged into a regular crystal lattice, but rather in a disordered pattern. Glassy materials are widely used in various settings, ...
Phys.org / Dormant black hole revives in under three years, brightening 10-fold in nearby galaxy
Astronomers monitoring a nearby active galaxy for six years have watched its supermassive black hole dramatically wake up, brightening by a factor of 10 across ultraviolet and X-ray wavelengths. The paper outlining the study ...
Phys.org / Biohybrid microrobots repair spinal cord by combining stem cells with magnetoelectric nanoparticles
Spinal cord injuries can have devastating consequences for those affected. Nerve cells in the spinal cord rarely regenerate naturally, while scarring often prevents the regrowth of nerve fibers. Modern therapies attempt to ...
Phys.org / For satellites as small as a briefcase, getting around in space just got a whole lot easier
MIT engineers are testing a new propulsion system that combines the power and speed of conventional chemical thrusters with the precision and fuel-efficiency of electrical thrusters. The system could enable the design of ...
Phys.org / Under Notre Dame cathedral, a 'dig of the century' unearths 1,700 years of history
Wilting in the summer sun, a line of tourists waits to climb Notre Dame cathedral and meet its gargoyles.
Phys.org / UN warns world to prepare for El Nino extreme weather
There is an 80% chance of the warming El Niño phenomenon developing between June and August, increasing the risk of extreme weather events, the World Meteorological Organization said Tuesday.
Phys.org / Robot fish could unravel how our ancient ancestors first learned to walk
Researchers have developed a fish-like robot that shows how some species of modern fish are able to walk on land, and could help unravel how early vertebrates evolved similar abilities hundreds of millions of years ago.
Phys.org / 'Mini-Neptune' exoplanets may have smoggy atmospheres similar to diesel exhaust
The astronauts circling Earth on the Artemis mission sent back beautiful clear photos of the continents, clouds, and oceans. But we might be the exception. Many planets in the universe may be hazed in clouds of soot, according ...
