OSU researchers prove magnetism can control heat, sound
Elemental particles that transmit both heat and sound -- known as acoustic phonons -- also have magnetic properties and can, therefore, be controlled by magnets, even for materials thought to be 'nonmagnetic,' such as semiconductors. This discovery 'adds a new dimension to our understanding of acoustic waves,' according to a landmark study confirmed by simulations conducted at the Ohio Supercomputer Center and recently published in the journal Nature Materials by researchers from The Ohio State University.

In battle of the sexes, a single night with a New York male is enough to kill
Men and women often enter relationships with different long-term goals. In the animal world, differences in approaches to reproductive success can lead to sexual conflict. In a new study, scientists show that sexual conflicts can evolve rapidly in natural populations, driven by competition among males for mating success.

Donuts, math, and superdense teleportation of quantum information
Quantum teleportation has been achieved by a number of research teams around the globe since it was first theorized in 1993, but current experimental methods require extensive resources and/or only work successfully a fraction of the time. Now, by taking advantage of the mathematical properties intrinsic to the shape of a donut -- or torus, in mathematical terminology -- a research team led by physicist Paul Kwiat of the University of Illinois at Urbana-Champaign has made great strides by realizing 'superdense teleportation.'

New study shows influence on climate of fresh water during last ice age
A new study shows how huge influxes of fresh water into the North Atlantic Ocean from icebergs calving off North America during the last ice age had an unexpected effect -- they increased the production of methane in the tropical wetlands.

Pinpointing natural cancer drug's true origins brings sustainable production a step closer

New human ancestor species from Ethiopia lived alongside Lucy's species
A new relative joins 'Lucy' on the human family tree. An international team of scientists, led by Dr. Yohannes Haile-Selassie of The Cleveland Museum of Natural History, has discovered a 3.3 to 3.5 million-year-old new human ancestor species. Upper and lower jaw fossils recovered from the Woranso-Mille area of the Afar region of Ethiopia have been assigned to the new species Australopithecus deyiremeda. This hominin lived alongside the famous 'Lucy's' species, Australopithecus afarensis.

Motivation and Emotion
Friendships start better with a smile
If you want to strike up a new relationship, simply smile. It works because people are much more attuned to positive emotions when forming new bonds than they are to negative ones. Don't try to fake it, however, because people can recognize a sincere smile a mile away. This is according to a study that sheds light on how relationships are formed and maintained. The findings are published in Springer's journal Motivation and Emotion.

Climate change debate fueled by 'echo chambers,' new study finds
A new study demonstrates the highly contentious debate on climate change is fueled in part by how information flows throughout policy networks. Researchers found that 'echo chambers' -- social network structures where individuals with the same viewpoint share information with each other -- may help explain why, despite a well-documented scientific consensus on the causes of global changes in climate, half of US senators voted earlier this year against an amendment affirming that climate change is human-induced.

Team pinpoints genes that make plant stem cells, revealing origin of beefsteak tomatoes
A team of scientists at Cold Spring Harbor Laboratory has identified a set of genes that control stem cell production in tomato. Mutations in these genes explain the origin of mammoth beefsteak tomatoes. More important, the research suggests how breeders can optimize fruit size in potentially any fruit-bearing crop.

How to get high-quality RNA from chemically complex plants
RNA extraction is a notoriously tricky and sensitive lab procedure, but new protocols out of the University of Florida are quicker, more effective, and more reliable than previous methods. The protocols are featured in bench-ready form with detailed notes and a troubleshooting guide in Applications in Plant Sciences. The protocols, which combine TRIzol, the TURBO DNA-free kit, and sarkosyl, were tested extensively on a diverse selection of woody, aromatic, and aquatic plants.

New computational technique advances color 3D printing process
Columbia Engineering professor Changxi Zheng has developed a technique that enables hydrographic printing, a widely used industrial method for transferring color inks on a thin film to the surface of 3D objects, to color these surfaces with the most precise alignment ever attained. His new computational method, which simulates the printing process and predicts color film distortion during hydrographic immersion, generates a colored film that guarantees exact alignment of the surface textures to the object.

Lowly 'new girl' chimps form stronger female bonds
Low-ranking 'new girl' chimpanzees seek out other gal pals with similar status, finds a new study. The results are based on 38 years' worth of daily records for 53 adult females in Gombe National Park, Tanzania, where Jane Goodall first started studying chimpanzees in the 1960s. The researchers are still working out whether the low-ranking pairs are true buddies, friends of convenience, or merely acquaintances.

Mission possible: This device will self-destruct when heated
Where do electronics go when they die? Most devices are laid to eternal rest in landfills. But what if they just dissolved away, or broke down to their molecular components so that the material could be recycled? University of Illinois researchers have developed heat-triggered self-destructing electronic devices, a step toward greatly reducing electronic waste and boosting sustainability in device manufacturing. They also developed a radio-controlled trigger that could remotely activate self-destruction on demand.
