A study in Pharmacological Research has found that small extracellular vesicles derived from embryonic stem cells (ESC-sEVs) alleviate osteoarthritis in cells and mice. Restoring senescent cells’ function Excessive […].
The treatment, given to four people with damaged corneas, seems safe but needs to be tested in larger trials.
Scientists have finally proven the existence of “supersolids,” a bizarre state of matter that behaves like both a liquid and a solid.
In a breakthrough, scientists confirmed superfluid properties in supersolids by observing quantized vortices. Using precision techniques, the team stirred a rotating supersolid, revealing unique vortex dynamics and offering new insights into the coexistence of solid and fluid characteristics. This discovery paves the way for studying exotic quantum matter and has implications for astrophysical phenomena.
Supersolids: A Quantum Paradox
Matter that behaves like both a solid and a superfluid at the same time might sound impossible. But more than 50 years ago, physicists predicted that quantum mechanics could allow such a state. In this unique state, collections of particles exhibit properties that seem contradictory. Francesca Ferlaino from the Department of Experimental Physics at the University of Innsbruck and the Institute of Quantum Optics and Quantum Information (IQOQI) at the Austrian Academy of Sciences explains, “It is a bit like Schrödinger’s cat, which is both alive and dead, a supersolid is both rigid and liquid.”

A mysterious electromagnetic mechanism may be more important than the firing of neurons in our brains to explain our awareness.
By Tamlyn Hunt
The neuron, the specialized cell type that makes up much of our brains, is at the center of today’s neuroscience. Neuroscientists explain perception, memory, cognition and even consciousness itself as products of billions of these tiny neurons busily firing their tiny “spikes” of voltage inside our brain.

Three SpaceX Falcon 9 rocket launch windows are scheduled to open back-to-back-to-back on Sunday, Monday and Tuesday from Florida’s Space Coast, a Federal Aviation Administration operations plan advisory indicates.
SpaceX has yet to officially announce this trio of missions — which would become the unparalleled 77th, 78th and 79th orbital rocket launches during a single calendar year from Cape Canaveral Space Force Station and NASA’s Kennedy Space Center.
