How do birds navigate? Quantum entanglement suggests

  • Birds’ navigation using Earth’s very faint magnetic fields suggests an incredible level of sensitivity.
  • There’s reason to think that sensitivity may be based on quantum entanglement in cryptochrome in their eyes.
  • Identifying the role of quantum physics in biology could lead, well, who knows where?

Okay, this is far from confirmed, but it’s pretty radical, and exciting. It’s a possible and plausible answer to a question that’s puzzled biologists ever since the manner in which birds navigate became apparent. The question is: How can birds possibly be able to perceive and follow something as faint as the Earth’s magnetic field? The possible answer? It may be that they perceive it through the interaction of entangled quantum particles in their eyes.

Researchers Find Evidence That Human Evolution Is Still Actively Happening

Scientists discover that humans are still evolving, with natural selection weeding out certain diseases.

A large new study says humans are still evolving. Scientists found that natural selection is weeding out harmful genetic mutations from our gene pool.

While we tend to think of evolution as laborious process that takes a long period of time, there also changes that can take place over one or two generations. Researchers from Columbia University analyzed DNA from 210,000 people in the United States and Britain and found that certain genetic variants, particularly those linked to Alzheimer’s disease and heavy smoking appear less frequently in people who live longer. This suggests that such genes are being less favored and may be on the way out of the human genome.
