Brain's reaction to certain words could replace passwords
You might not need to remember those complicated e-mail and bank account passwords for much longer. According to a new study, the way your brain responds to certain words could be used to replace passwords.

Though people can distinguish among millions of colors, we have trouble remembering specific shades because our brains tend to store what we've seen as one of just a few basic hues.

Researchers simulate behavior of 'active matter'
From flocks of starlings to schools of fish, nature is full of intricate dynamics that emerge from the collective behavior of individuals. In recent years, interest has grown in trying to capture similar dynamics to make self-assembling materials from so-called 'active matter.' Researchers from Brown University have shed new light on the dynamics of one type of active matter known as active colloids.

Coupled human and natural systems explain change on the Mongolian Plateau
Using well-established metrics of social, economic, and ecosystem functions, researchers have achieved a holistic view of coupled human and natural systems on the Mongolian Plateau. This view reveals a dynamic system of interacting factors, with widely varied results in the plateau's two geopolitical regions.

At peak fertility, women who desire to maintain body attractiveness report they eat less
Women near peak fertility -- those nearing ovulation -- and who are motivated to manage their body appearance, reported they desire to lose weight and so ate fewer calories. Those are findings from three new independent studies, says lead author Andrea Meltzer, Southern Methodist University, Dallas. Previous ovulation research has attributed reduced eating solely to neuroendocrinological factors. The new findings indicate an additional factor is a woman's concern about her body appearance, say Meltzer and her co-authors.

New sensing tech could help detect diseases, fraudulent art, chemical weapons
Discovered in the 1970s, SERS is a sensing technique prized for its ability to identify chemical and biological molecules in a wide range of fields. It has been commercialized, but not widely. That may soon change. An international research team led by University at Buffalo engineers has developed nanotechnology that promises to make SERS simpler and more affordable.

Invasive microbe protects corals from global warming, but at a cost
An invasive species of symbiotic micro-alga has spread across the Caribbean Sea, according to an international team of researchers. These single-cell algae, which live within the cells of coral animals, are improving the resilience of coral communities to heat stress caused by global warming, but also are diminishing the abilities of corals to build reefs.

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 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.
