How are nerve impulses exchanged between cells?

The nervous system in people and animals consists of many different cells. In cells, signals are conveyed by small electrical currents and by chemical substances. By measuring changes in electrical charges in a very large nerve fiber from a species of octopus, Andrew Huxley (pictured), together with Alan Hodgkin was able to show how nerve impulses are exchanged between cells.

In 1952 they demonstrated that a fundamental mechanism involves the passage of sodium and potassium ions in opposite directions in and out through the cell wall, which gives rise to electrical charges.

Huxley and Hodgkin were awarded the 1963 Nobel Prize in Physiology or Medicine for their discovery.

Scientists capture images of a new quantum phase in electron molecular crystals

Scientists capture images of a new quantum phase in electron molecular crystals Electrons typically travel at high speeds, zipping through matter unbound. In the 1930s, physicist Eugene Wigner predicted that electrons could be coaxed into stillness at low densities and cold temperatures, forming an electron ice that would later be called the Wigner crystal.

New research contradicts the idea that male wasps are generally harmless. After a scientist was stung by a male mason wasp (Anterhynchium gibbifrons), she realized it had pierced her skin using its sharp, two-pronged genitalia. To test whether these male pseudostingers might deter attackers, researchers placed male mason wasps inside an enclosure with one of their predators, a tree frog. As the frogs attacked the wasps every time, the wasps fought back with their piercing pen*ses—and got spat back out about one-third of the time (as seen in the video). The findings represent the first evidence of male genitalia playing a defensive role in the animal kingdom. Learn more: https://scim.ag/MaleWasps #ScienceReels
