Helping Family is Key for Social Birds
Social birds that forgo breeding to help to raise the offspring of other group members are far more likely care for their own close relatives than for more distant kin, a new study has found. (more…)

Chicken with Plums
Synopsis
Teheran, 1958. Since his beloved violin was broken, Nasser Ali Khan, one of the most renowned musicians of his day, has lost all taste for life. Finding no instrument worthy of replacing it, he decides to confine himself to bed to await death. As he hopes for its arrival, he plunges into deep reveries, with dreams as melancholic as they are joyous, taking him back to his youth and even to a conversation with Azraël, the Angel of Death, who reveals the future of his children… As pieces of the puzzle gradually fit together, the poignant secret of his life comes to light: a wonderful story of love which inspired his genius and his music… (more…)
New Technique Controls Crystalline Structure of Titanium Dioxide
Researchers from North Carolina State University have developed a new technique for controlling the crystalline structure of titanium dioxide at room temperature. The development should make titanium dioxide more efficient in a range of applications, including photovoltaic cells, hydrogen production, antimicrobial coatings, smart sensors and optical communication technologies.
Titanium dioxide most commonly comes in one on of two major “phases,” meaning that its atoms arrange themselves in one of two crystalline structures. These phases are “anatase” or “rutile.” The arrangement of atoms dictates the material’s optical, chemical and electronic properties. As a result, each phase has different characteristics. The anatase phase has characteristics that make it better suited for use as an antibacterial agent and for applications such as hydrogen production. The rutile phase is better suited for use in other applications, such as photovoltaic cells, smart sensors and optical communication technologies. (more…)

Studies of frogs may lead to better hearing aids
When Mark Bee talks to his 106-year-old grandmother alone, her two enormous hearing aids enable her to understand him well.
“But at a table at Thanksgiving, with everybody talking, the devices don’t do well,” says Bee, an associate professor of ecology, evolution and behavior at the University of Minnesota.
Her difficulty in a noisy situation is called the cocktail party problem, after the background babble that stymies many hearing-impaired people trying to pick out individual voices at a party. But in ponds all over the world, frogs handle a similar problem, and Bee hopes to learn enough about how they do it to put the principles to work helping people like his grandmother. (more…)
Metamolecules That Switch Handedness at Light-Speed
Researchers Develop Optically Switchable Chiral Terahertz Metamolecules
A multi-institutional team of researchers that included scientists with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has created the first artificial molecules whose chirality can be rapidly switched from a right-handed to a left-handed orientation with a beam of light. This holds potentially important possibilities for the application of terahertz technologies across a wide range of fields, including reduced energy use for data-processing, homeland security and ultrahigh-speed communications.

Training Improves Recognition of Rapid-Fire Objects
“Attentional blink” is the term psychologists use to describe our inability to recognize a second important object if we see it less than half a second after a first one. It always seemed impossible to overcome, but in a new paper in the Proceedings of the National Academy of Sciences, Brown University psychologists report they’ve found a way.
PROVIDENCE, R.I. [Brown University] — So far it has seemed an irreparable limitation of human perception that we strain to perceive things in the very rapid succession of, say, less than half a second. Psychologists call this deficit “attentional blink.” We’ll notice that first car spinning out in our path, but maybe not register the one immediately beyond it. It turns out, we can learn to do better after all. In a new study researchers now based at Brown University overcame the blink with just a little bit of training that was never been tried before.

Killing of Bin Laden Offers Insight into “The Business of Martyrdom”
COLUMBUS, Ohio – The way the U.S. military killed Osama bin Laden sent a message every bit as powerful as the fact that he was killed in the first place, according to the author of a new history of suicide bombing.
The fact that bin Laden was killed by a team of highly trained soldiers – and not by a drone or bomb – spoiled the grand narrative of brave Muslim fighters vs. U.S. technology that bin Laden and al Qaeda had developed in their war against the United States.
“Bin Laden had built up this image of himself and al Qaeda as a morally superior David against the technological Goliath that is the United States,” said Jeffrey Lewis, a lecturer in the International Studies program at Ohio State University. (more…)
