Mysterious Signals Hint That Fast Radio Bursts Are More Active Than We Thought
By Meril Jeffery John.J 29. February 2020
Fast radio bursts, or FRBs, are millisecond-long bursts of radio waves in space. Individual radio bursts emit once and don't repeat. But repeating fast radio bursts are known to send out short, energetic radio waves multiple times. And usually...

A burst of gravitational waves has blasted Planet Earth
By Meril Jeffery John.J 29. February 2020
A mysterious cosmic event might have ever-so-slightly stretched and squeezed our planet last week. On Jan. 14, astronomers detected a split-second burst of gravitational waves, distortions in space-time. But researchers don't know where this burst...

Tardigrades Are Basically Indestructible, But Scientists Just Found Their Weak Point
By Meril Jeffery John.J 10. February 2020
Tardigrades are tough little critters. When conditions get nasty, they can dry out, reconfigure their bodies and enter suspended animation - called dessication - for years. You can throw virtually anything at them: frozen temperatures, zero oxygen,...

New research provides evidence of strong early magnetic field around Earth
By Meril Jeffery John.J 6. February 2020
Deep within Earth, swirling liquid iron generates our planet's protective magnetic field. This magnetic field is invisible but is vital for life on Earth's surface: It shields the planet from harmful solar wind and cosmic rays.

Experiment reveals strange ghost particles in Antarctica
By Meril Jeffery John.J 6. February 2020
When physicists detected signals of high-energy neutrinos coming from a rather unlikely direction in the cosmos, they naturally went looking for a powerful source that might explain it.
