Scientists say the constant motion of living cells could be a hidden source of electrical power
Cells have always hummed with activity. They make their own energy, package it into molecules like ATP, and spend it ...
Research carried out at the University of Pennsylvania has definitively measured and described the Brownian motion of an isolated ellipsoidal particle, completing a path laid out by Einstein 100 years ...
Normally, noise is something we scientists try to avoid. In the most advanced physics experiments, the goal is usually to measure something new. If you ever ask the experimenters why it took them so ...
A group of physicists in Italy believes that mobile bacteria could convert chemical energy into mechanical energy by pushing on the teeth of tiny gear wheels. The researchers used computer simulations ...
Our Milky Way is not alone in the universe. Surrounding us are numerous satellite galaxies, taking part in a continuous grand dance. But how do these neighbouring galaxies behave, how do they interact ...
IN 1905, Albert Einstein published five papers that shook the world of physics. His elegant arguments and conclusions were marvels of physical intuition that addressed dilemmas raised by experimental ...
Occasionally, scientists stumble upon what seems to be a free lunch. But they’re not concerned about possibly violating the laws of economics. It would be much more shocking to break the laws of ...
