E-scooters: a transport 'tsunami' flooding cities worldwide
They appeared in June last year as Paris was waking up from its annual all-night Festival of Music: hundreds of green-and-black electric scooters dotting the pavements of the capital.

For years, physicists have assumed that Cooper pairs, the electron duos that enable superconductors to conduct electricity without resistance, were two-trick ponies. The pairs either glide freely, creating a superconducting ...

Superconductors and magnetic fields do not usually get along. But a research team led by a Brown University physicist has produced new evidence for an exotic superconducting state, first predicted a half-century ago, that ...

In the particle world, sometimes two is better than one. Take, for instance, electron pairs. When two electrons are bound together, they can glide through a material without friction, giving the material special superconducting ...

(PhysOrg.com) -- One of the basic components of a functional, cooperative society is a code of law, where the laws are usually enforced by some kind of incentive. Social incentives can either be positive (rewards) or negative ...
(Phys.org)—Physicists have proposed that a hypothetical form of matter called "unparticles" may play a key role in mediating superconductivity—the ability of certain materials to conduct electricity with zero resistance.
A game to study human behavior has shown punishment is an ineffective means for promoting cooperation among players. The result has implications for understanding how cooperation has evolved to have a formative role in human ...

Cooperation or co-operation is the process of working or acting together. In its simplest form it involves things working in harmony, side by side, while in its more complicated forms, it can involve something as complex as the inner workings of a human being or even the social patterns of a nation. It is the alternative to working separately in competition. Cooperation can also be accomplished by computers, which can handle shared resources simultaneously, while sharing processor time.
