An undergraduate astrophysics student at UC Berkeley has found three unusual galaxies—cataloged as Shapiro Dwarf Galaxies I, II and III. Each galaxy is far from other galaxies and has stopped making stars, a combination that is extremely rare. The discovery, published in The Astrophysical Journal, provides compelling observational evidence of a long-held astronomical theory.

“Dwarf galaxies exist both in isolation and as satellites around larger galaxies like our own Milky Way,” said Julian Shapiro, the study’s sole author, who conducted his research while still in high school...

Today, many physicists are actively exploring how light could be used to link objects through quantum entanglement. By fully harnessing the effect, they hope to unlock a wide array of applications, from secure communication networks spanning vast distances to sensitive new tests of the fundamental laws of physics.

Through new research published in Science, a team led by Francesco Marin at the University of Florence has taken an important step toward this goal by entangling the motion of a tiny levitating glass sphere with light, without needing to cool their experiment to ultralow temperatures.

Scientists found that five seemingly unrelated conditions, including longCovid, ME/CFS, and PTSD, may disrupt many of the same biological networks involved in immunity, metabolism, and cellular energy. The findings could help explain their shared symptoms and may open the door to new blood tests and treatments.

Researchers at the University of East Anglia and Oxford BioDynamics have identified a possible biological connection that could help explain why profound exhaustion appears across conditions as different as long Covid and PTSD.

The new study, published in the Journal of Translational Medicine, point...
