Is dark matter's main rival theory dead? The Cassini spacecraft and other recent tests may invalidate MOND

One of the biggest mysteries in astrophysics today is that the forces in galaxies do not seem to add up. Galaxies rotate much faster than predicted by applying Newton's law of gravity to their visible matter, despite those ...

Rolling with the punches: How mantis shrimp defend against high-speed strikes

Mantis shrimp are small creatures known for their superlatives. Their eyes have 12 to 16 different color receptors versus our own three, and can detect the polarization of light. Their punches are famously fast, accelerating ...

Where space weather starts: Self-consistent propagation of flux ropes in realistic coronal simulations

The effects of space weather extend out across our entire solar system, but this is a simulation of where everything starts: the sudden, violent, emergence of a "flux rope" out of the sun's magnetic field and into the solar ...

How aging clocks tick: New study points to stochastic changes in cells

Aging clocks can measure the biological age of humans with high precision. Biological age can be influenced by environmental factors such as smoking or diet, thus deviating from chronological age that is calculated using ...

As climate change amplifies urban flooding, here's how communities can become 'sponge cities'

"When it rains, it pours" once was a metaphor for bad things happening in clusters. Now it's becoming a statement of fact about rainfall in a changing climate.
