Physicists propose search for fourth neutrino

(PhysOrg.com) -- Physicists know that neutrinos (and antineutrinos) come in three flavors: electron, muon, and tau. In several experiments, researchers have detected each of the neutrino flavors and even watched them “oscillate” ...

Ants follow Fermat's principle of least time

(Phys.org) —Ants have long been known to choose the shortest of several routes to a food source, but what happens when the shortest route is not the fastest? This situation can occur, for example, when ants are forced to ...

The Physics of Friendship

By comparing people to mobile particles randomly bouncing off each other, scientists have developed a new model for social networks. The model fits with empirical data to naturally reproduce the community structure, clustering ...

Iron-nitrogen compound forms strongest magnet known

(PhysOrg.com) -- A group of scientists from the University of Minnesota say that Fe16N2 crystals are more magnetic than the most magnetic material previously known, and its magnetism exceeds the predicted limit of magnetism ...

Magnesium: Alternative Power Source

Why Life Originated (And Why it Continues)

(PhysOrg.com) -- Today, scientists understand pretty well how life evolves, by mechanisms based on Darwin’s theory of natural selection for survival of the fittest. However, Darwin’s 1859 classic, On the Origin of Species, ...
