Phys.org / Hubble identifies a near-invisible galaxy that may be 99% dark matter

In the vast tapestry of the universe, most galaxies shine brightly across cosmic time and space. Yet a rare class of galaxies remains nearly invisible—low-surface-brightness galaxies dominated by dark matter and containing ...

Phys.org / 'Boomerang' earthquake simulations suggest ricocheting ruptures may be more common than previously thought

An earthquake typically sets off ruptures that ripple out from its underground origins. But on rare occasions, seismologists have observed quakes that reverse course, further shaking up areas that they passed through only ...

Phys.org / New 'Mars GPS' lets Perseverance pinpoint its location within 25 centimeters

Imagine you're all alone, driving along in a rocky, unforgiving desert with no roads, no map, no GPS, and no more than one phone call a day for someone to inform you exactly where you are. That's what NASA's Perseverance ...

Phys.org / Chemistry-powered 'breathing' membrane opens and closes tiny pores on its own

Ion channels are narrow passageways that play a pivotal role in many biological processes. To model how ions move through these tight spaces, pores need to be fabricated at very small length scales. The narrowest regions ...
