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.

One step closer to a single-molecule device
Columbia Engineering professor Latha Venkataraman has designed a new technique to create a single-molecule diode, and, in doing so, she has developed molecular diodes that perform 50 times better than all prior designs. Venkataraman's group is the first to develop a single-molecule diode that may have real-world technological applications for nanoscale devices.

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.

Penn researchers show that mental 'map' and 'compass' are two separate systems
In a new study in mice, researchers at the University of Pennsylvania have shown that mental 'map' and 'compass' systems work independently. A cue that unambiguously provided both types of information allowed the mice to determine their location but not the direction they were facing.

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.

Symbiosis turns messy in 13-year cicadas
Bacteria that live in the guts of cicadas have split into many separate but interdependent species in a strange evolutionary phenomenon that leaves them reliant on a bloated genome, a new paper by CIFAR Associate Fellow John McCutcheon's lab (University of Montana) has found.

Partly human yeast show a common ancestor's lasting legacy
Despite a billion years of evolution separating humans from the baker's yeast in their refrigerators, hundreds of genes from an ancestor that the two species have in common live on nearly unchanged in them both, say biologists at The University of Texas at Austin. The team created thriving strains of genetically engineered yeast using human genes and found that certain groups of genes are surprisingly stable over evolutionary time.

Study reveals how eastern US forests came to be
Spring visitors to Great Smoky Mountains or the Blue Ridge Parkway will see ridges and valleys covered in flowering mountain laurels, rhododendrons, tulip poplars, dogwoods, black locusts and silverbell trees. A new study of nearly all the trees and shrubs in the southern Appalachians suggests that roughly half of the species can trace their relatives to thousands of miles away in Asia. Most of the rest likely arose within North America, the researchers say.

Caltech astronomers observe a supernova colliding with its companion star
On May 3, 2014, Caltech astronomers working on a robotic observing system known as the intermediate Palomar Transient Factory discovered a Type Ia supernova -- supernova known as 'standardizable candles' because they allow astronomers to gauge cosmic distances -- located 300 million light-years away. The data collected offer unprecedented insight into the origin of this type of supernovae, and suggest the possibility that it actually comes in two distinct varieties.
