Almost three quarters of adolescents experience depression or anxiety

Posted by in categories: neuroscience, quantum physics

MIT physicists and colleagues have for the first time measured the geometry, or shape, of electrons in solids at the quantum level. Scientists have long known how to measure the energies and velocities of electrons in crystalline materials, but until now, those systems’ quantum geometry could only be inferred theoretically, or sometimes not at all.

The work, reported in the November 25 issue of Nature Physics, “opens new avenues for understanding and manipulating the quantum properties of materials,” says Riccardo Comin, MIT’s Class of 1947 Career Development Associate Professor of Physics and leader of the work.

“We’ve essentially developed a blueprint for obtaining some completely new information that couldn’t be obtained before,” says Comin, who is also affiliated with MIT’s Materials Research Laboratory and the Research Laboratory of Electronics.

Black holes may not exist as we know them, but fuzzballs might

Posted by in categories: cosmology, particle physics, quantum physics, singularity

String theory proposes that all particles and forces are made of tiny, vibrating strings, which form the fundamental building blocks of the universe. This framework offers a potential solution to the long-standing paradoxes surrounding black holes, such as their singularities—infinitely tiny points where the laws of physics break down—and the Hawking radiation paradox, which questions the fate of information falling into black holes.

Fuzzballs replace the singularity with an ultra-compressed sphere of strings, likened to a neutron star’s structure but composed of subatomic strings instead of particles. While the theory remains incomplete, its implications are significant, offering an alternative explanation for phenomena previously attributed to black holes.

To differentiate between black holes and fuzzballs, researchers are turning to gravitational waves—ripples in spacetime caused by cosmic collisions. When black holes merge, they emit specific gravitational wave signatures that have so far aligned perfectly with Einstein’s general relativity. However, fuzzballs might produce subtle deviations from these patterns, providing a way to confirm their existence.

Ancient volcanic ash on Mars could offer new clues in search for extraterrestrial life

Posted by in categories: alien life, climatology

Researchers believe dark rocks at the site of a future Mars rover landing mission may be left over from ancient volcanic eruptions, and may be protecting signs of life — if there ever was life on Mars.
