Duke launches autism research app with global reach
'Autism & Beyond,' a free app developed at Duke, uses an iPhone's self-facing camera to assess a child's emotional state while viewing various stimuli on its display screen. The app is built on Apple's open source ResearchKit, promising medical researchers a global reach with standardized consent forms and protocols.

Shift in weaning age supports hunting-induced extinction of Siberian woolly mammoths
Chemical clues about weaning age embedded in the tusks of juvenile Siberian woolly mammoths suggest that hunting, rather than climate change, was the primary cause of the elephant-like animal's extinction.

New concept to help set priorities in water management
The basic principle behind most strategies aimed at renaturalizing ecosystems is to increase biodiversity by restoring natural habitat structure. These projects often do not result in the success researchers had hoped for because the complexity of ecological relationships is so vast. Researchers have now developed a theoretical framework -- the concept of ecological simplification -- aimed at closing this gap. They tested it in two iconic river landscapes.

Mathematicians find 'magic key' to drive Ramanujan's taxi-cab number
Taxi-cab numbers, among the most beloved integers in math, trace their origins to 1918 and what seemed like a casual insight by the Indian genius Srinivasa Ramanujan. Now mathematicians at Emory University have discovered that Ramanujan did not just identify the first taxi-cab number -- 1729 -- and its quirky properties. He showed how the number relates to elliptic curves and K3 surfaces -- objects important today in string theory and quantum physics.

A successful intervention boosts the gender diversity of STEM faculty
Using a three-step intervention derived from self-determination theory, an interdisciplinary team from Montana State University demonstrated a potential means of substantially increasing gender diversity in STEM-faculty hiring. Search committees in the intervention group were 6.3 times more likely to make an offer to a woman candidate.

Plant hormone 'switch' unravels chromatin to form flowers, penn biologists find
University of Pennsylvania researchers identified a hormone-mediated 'chromatin switch' that directs a plant to form flowers. In the absence of auxin, genes that initiate flower formation are tucked away in tangled chromatin, a tightly packed bundle of DNA. But, in the hormone's presence, proteins are recruited to unravel chromatin and make the genes responsible for flower formation more accessible.

RIT receives 2 cyber-security funding awards
Shanchieh Yang, a faculty-researcher at Rochester Institute of Technology, was recently awarded grant funding from the National Science Foundation and National Security Agency for two cyber security projects. They are intended to get ahead of attackers by understanding early warnings to prevent high-impact actions from happening, and by extracting important characteristics of these warnings and transforming them into a preemptive, tactical system.

What does it take to escape the water? Plankton have clues
Dolphins and whales may attract a lot of attention when they leap dramatically out of the water. But aquatic animals thousands of times smaller are accomplished jumpers, too. Their acrobatics often go unnoticed, but understanding them could help improve engineering processes, like oil refining and wastewater treatment, that rely on controlling the interaction of small particles with air-water interfaces.

Pebbles on Mars likely traveled tens of miles down a riverbed, Penn study finds

Fungi at root of plant drugs that can help, or harm, sick monarch butterflies
Previously, biologists discovered that butterflies use plant toxins as a drug to cure their offspring of parasitic infections. Now they've dug a little deeper and found that the fungi associated with the roots of milkweed plants change both the nutritional and medicinal chemistry of milkweed leaves.

Sixth sense: How do we sense electric fields?
A variety of animals are able to sense and react to electric fields, and living human cells will move along an electric field, for example in wound healing. Now UC Davis researchers have found the first actual 'sensor mechanism' that allows a living cell detect an electric field.
