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 / 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 / Tiny membrane tethers revealed as key to plant cell survival in drought
Water deficit resistance in plants has long been a topic of interest for cultivating reliable crops. Some plants can alter their above-ground structure to lock in moisture, while others develop deep, industrious roots that ...
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 / Predicting physics without parameter tuning: A faster computational approach
Numerical simulations in physics often require estimating a multitude of parameters, making the process computationally expensive and complex. Researchers at University of Tsukuba have introduced a new method called the multiparameter ...
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 / 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 / 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 / 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 / New mantises planking their way to urban dominance
A team of scientists have discovered and named three new "leaf-planking" praying mantis species and recorded another mantis species turning up far from its assumed habitat. JCU Ph.D. candidate Matthew Connors recently discovered ...
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 ...
