Phys.org / Earth's chorus waves show limited link to rapid electron loss from radiation belts

The Van Allen radiation belts are huge, doughnut-shaped regions of highly energetic charged particles trapped by Earth's magnetosphere. These charged particles play a major role in space weather, so studying them is important ...

Phys.org / A single temporary stimulus may redirect cell fate without permanently altering genes

Which genes need to be controlled to guide a stem cell toward a desired cell type or modulate an immune cell's inflammatory response? A Korean research team has developed a general-purpose computational framework that identifies ...

Phys.org / Largest dataset of its kind could clarify how massive stars shaped early galaxies

The more astronomers learn about the universe's earliest galaxies, the stranger they seem. Many of their surprising properties may be explained by differences between their massive stars and those in galaxies like our own ...

Phys.org / Carbon nanotube foams reveal a new kind of mechanical memory

In their earliest years of development, computers used mechanical gears and levers to store information. Today, researchers are exploring whether a material itself can hold onto information, storing memory in how it bends ...
