Phys.org / Scientists measure hidden quantum forces that could power a new generation of pharmaceutical drugs

It's one thing to design a pharmaceutical drug. It's another to know if and why it actually works; not on paper or in a computer model, but inside the chaotic world of living systems, where proteins twist into shape, atoms ...

Phys.org / Why these birds meet again in Africa: Flycatcher study reveals how genes and environment guide 13,000‑km migrations

Migratory birds such as the pied flycatcher typically have wintering locations in Africa close to others from the same breeding population. That means that birds breeding in the Netherlands run into each other again in Africa, ...
