Cells exposed to an inflammatory signaling molecule are quicker to commit suicide -- but speed can lead to mistakes.
Artificial "protocells" suggest the complex biochemical mechanisms used by living cells could have originated in simple bubbles.
New finding suggests muscle tone and wing posture help the insects execute an upside-down backflip, even when anesthetized.
By mimicking the diabolical ironclad beetles' wing cases, engineers may be able to build stronger joints for applications such as airplanes.
Researchers found that confined tumors are more resistant to drug treatments.
Cryo-electron microscopy helps scientists see the structure of biomolecules down to each individual atom.
So-called cryo-electron microscopy can see the atoms of biological proteins in water.
Insights may lead to advances in solar power.
