The growth of an organism rides on a pattern of waves

When an egg cell of almost any sexually reproducing species is fertilized, it sets off a series of waves that ripple across the egg's surface. These waves are produced by billions of activated proteins that surge through ...

Dancing hairs alert bees to floral electric fields

Tiny, vibrating hairs may explain how bumblebees sense and interpret the signals transmitted by flowers, according to a study by researchers at the University of Bristol.

Smart material prototype challenges Newton's laws of motion

For more than 10 years, Guoliang Huang, the Huber and Helen Croft Chair in Engineering at the University of Missouri, has been investigating the unconventional properties of "metamaterials"—an artificial material that exhibits ...

Review: Use power outlets as a Wi-Fi alternative

(AP) -- Setting up a Wi-Fi network at home has gotten much easier, yet the process can still be daunting. Or the wireless signal won't reach everywhere. A good alternative that has gotten little attention involves your electric ...

Brain-Like Computer Closer to Realization

(PhysOrg.com) -- Almost since computing began, scientists and technologists have been fascinated with the idea of a computer that works similarly to the human brain. In 2008, the first "memristor" was built, a device that ...

Bacteria recruit other species with long-range electrical signals

Biologists at UC San Diego who recently found that bacteria resolve social conflicts within their communities and communicate with one another like neurons in the brain have discovered another human-like trait in these apparently ...
