Third time’s the charm for a row of faint galaxies without dark matter

by quasarn01 | Jun 16, 2026 | Astronomy

A Yale-led team of astronomers has found a third galaxy devoid of dark matter—located alongside the other two in a formation that has never been seen before. Astronomers have followed a faint, cosmic trail of gas to a third galaxy that has no dark matter. Go to...

High degree of quantum entanglement detected for first time in centimeter-sized crystal of strange metal

by quasarn01 | Jun 16, 2026 | Latest in Physics

Many quantum effects can be observed only when a small number of particles is studied—individual atoms, molecules or photons, for example, carefully shielded from the rest of the world. But what about macroscopic objects, consisting of an unimaginably large number of...

Physicists identify upper limit to resistivity in a pure metal

Experimental atomic physicists have discovered there is a maximum amount of electrical resistance, or resistivity, that can result from collisions between electrons. Go to Source

Intermolecular collisions may explain why organic radical fluids become unusually magnetic

by quasarn01 | Jun 16, 2026 | Latest in Physics

Certain substances can become magnetic when exposed to an external magnetic field. Magnetic susceptibility measures how easily a material can be magnetized. Materials known as organic radicals have been noted to possess anomalously large magnetic susceptibility....

Future Martian colonists will need a new relativistic clock

by quasarn01 | Jun 16, 2026 | Astronomy

We think of atomic clocks as the definitive timekeepers. They are famous for being accurate down to the picosecond. Unfortunately, they are still subject to general relativity, so if you put them on a different planet, they will track time slightly faster or slower...
