Phys.org / Astrophysicists map how many ghost particles all the Milky Way's stars send towards Earth

They're called ghost particles for a reason. They're everywhere—trillions of them constantly stream through everything: our bodies, our planet, even the entire cosmos. These so-called neutrinos are elementary particles ...

Phys.org / Cells use Morse code-like rhythms to coordinate growth

Cells experience many different types of stress, such as starvation or stress caused by too much salt or too high a temperature. Insulin signals respond to such stress signals by sending the protein DAF-16 into the cell nucleus ...

Phys.org / How population bottlenecks shape bacterial cooperation and competition

Microbes often display cooperative behavior in which individual cells put in work and sacrifice resources to collectively benefit the group. But sometimes, "cheater" cells in the group may reap the benefits of this cooperation ...
