Trapping antihydrogen atoms at the European Organization for Nuclear Research (CERN) has become so routine that physicists are confident that they can soon begin experiments on this rare antimatter equivalent of the hydrogen atom, according to researchers at the University of California, Berkeley.

The fact that first graders grow crystals for science projects might lead you to think that physicists know how these snazzy shapes form and unform. Alas, there is still a big blank spot in physics textbooks where the theory of crystal melting should be.

In a game of one-upmanship, a Chinese team of physicists has figured out how to entangle eight photons simultaneously and to observe them in action; the previous record was six. In a paper published in arXiv, the team from the University of Science and Technology of China in Hefei, describe how they were able to convert a single photon into two entangled photons, using a nonlinear crystal, and then how they repeated that process with one of the paired photons produced, while holding the other in place, producing another pair, and then did it repeatedly until they had eight photons all entangled together, all held in place and all observable for a period of time.

Expanding highways and roads increases congestion by creating more demand--and building more public transportation doesn't help the problem. A quick drive on one of Los Angeles's many freeways illustrates the fact that having more roads doesn't necessarily prevent traffic. Now a study from the University of Toronto confirms it: Expanding highways and roads increases congestion by creating more demand.

By Ewen Callaway of Nature magazine Fossilized teeth of early human ancestors bear signs that females left their families when they came of age, whereas males stayed close to home. A chemical analysis of australopithecine fossils ranging between roughly 1.8 million and 2.2 million years old from two South African caves finds that teeth thought to belong to females are more likely to have incorporated minerals from a distant region during formation than those from males

If we're burning it, we might as well use the waste.

An international research team has successfully developed a widely applicable method for discovering the physical foundations of complex fluids for the first time. Researchers at the University of Vienna and University of Rome have developed a microscopic theory that describes the interactions between the various components of a complex polymer mixture. This approach has now been experimentally proven by physicists from Julich, who conducted neutron scattering experiments in Grenoble

(PhysOrg.com) -- University of Michigan physicists used the electric fields generated by intersecting laser beams to trap and manipulate thousands of microscopic plastic spheres, thereby creating 3-D arrays of optically induced crystals.

Ice-road truckers may become an endangered species as climate change intensifies in the Arctic, concludes a new study that examines how rising temperatures will alter the transportation mix in the far north. Researchers at the University of California, Los Angeles, say that by midcentury, warming will significantly limit the areas suitable for constructing temporary roads each winter. The season for using such roads, key transport routes for cargo, will also shorten.

The rare metals that go into clean technology are already in short supply. Without a way to get them out of our old electronics, we could run out before we know it

The article, “Religious factors and hippocampal atrophy in late life,” by Amy Owen and colleagues at Duke University represents an important advance in our growing understanding of the relationship between the brain and religion. The study showed greater atrophy in the hippocampus in individuals who identify with specific religious groups as well as those with no religious affiliation. It is a surprising result, given that many prior studies have shown religion to have potentially beneficial effects on brain function, anxiety, and depression.
