Weird World of Quantum Physics May Govern Life
by Clara Moskowitz
The bizarre rules of quantum physics are often thought to be restricted to the microworld, but scientists now suspect they may play an important role in the biology of life.
Evidence is growing for the involvement of quantum mechanics in a wide range of biological processes, including photosynthesis, bird migration, the sense of smell, and possibly even the origin of life…
These oddities generally don’t affect everyday macroscopic objects, which are thought to be too hot and wet for delicate quantum states to withstand. But it seems nature may have found ways to harness quantum mechanics to power some of its most complex and vital systems. Quantum mechanics refers to the strange set of rules that governs the behavior of subatomic particles, which can travel through walls, behave like waves and stay connected over vast distances.
For ages, scientists have puzzled how birds could achieve such a feat of navigation, assuming they possess some ability to sense direction based on Earth’s magnetic field. One area where clues are implicating quantum mechanics is the internal compasses of birds and other migratory animals. Many bird species migrate thousands of miles every year to return not just to the same region, but to the exact same breeding spot.
Mounting evidence now suggests birds may be relying on quantum entanglement — the strange ability of particles to share properties even when separated, so that if an action is performed on one, the other feels its consequences…
