Study reveals ways powerful 'master gene' regulates physical differences between sexes
A study by scientists at Indiana University has found that the master gene that regulates differences between males and females plays a complex role in matching the right physical trait to the right sex. The research, published Feb. 27 in the journal Nature Communications, reveals new details about the behavior of the gene called 'doublesex,' or dsx.

New pop-up strategy inspired by cuts, not folds
Origami-inspired materials use folds in materials to embed powerful functionality. However, all that folding can be pretty labor intensive. Now, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) are drawing material inspiration from another ancient Japanese paper craft -- kirigami.

Princeton-Intel collaboration breaks new ground in studies of the brain
Princeton University and Intel researchers have collaborated to develop software that allows for 'decoding digital brain data' to reveal how neural activity gives rise to learning, memory and other cognitive functions. The software can be used in real time during an fMRI brain scan.

Interactive health apps may inspire healthy behaviors, but watch the tone
Just like real doctors and nurses, online health tools with good -- but controlled -- communication skills can promote healthier lifestyles, according to researchers. However, if their tone is conversational, these tools may lull users into a false sense of comfort, they add. In a study, people who experienced a back-and-forth interaction with an online health risk assessment website were more likely to follow the health behaviors suggested by the tool.

Colorado School of Mines and Virginia Tech to create minerals industry consortium
Colorado School of Mines is teaming with Virginia Tech to develop an integrated approach to locating, characterizing and visualizing mineral resources. The goal is to advance mining operations and boost exploration success rates while minimizing financial risk and environmental impact. The proposed Center for Advanced Subsurface Earth Resource Models would provide exploration and mining companies worldwide with new 3-D subsurface geological models, informing decision-making and risk management at all stages of the mining life cycle.

New polymer additive could revolutionize plastics recycling
Only 2 percent of the 78 million tons of manufactured plastics are currently recycled into similar products because polyethylene (PE) and polypropylene (PP), which account for two-thirds of the world's plastics, have different chemical structures and cannot be efficiently repurposed together. That could all change with a discovery by a Cornell University research team.

Bored by physical therapy? Focus on citizen science instead
Researchers have devised a method by which patients improved their repetitive rehabilitative exercises by contributing to scientific projects in which massive data collection and analysis is needed. The citizen science activity entailed the environmental mapping of a polluted body of water with a miniature instrumented boat, which was remotely controlled through physical gestures tracked by the Microsoft Kinect, a low-cost motion capture system.

Melting sea ice may be speeding nature's clock in the Arctic
Spring is coming sooner to some plant species in the low Arctic of Greenland, while other species are delaying their emergence amid warming winters. The changes are associated with diminishing sea ice cover, according to a study published in the journal Biology Letters and led by the University of California, Davis.

Vast luminous nebula poses a cosmic mystery
Astronomers have found an enormous, glowing blob of gas in the distant universe, with no obvious source of power for the light it is emitting. Called an 'enormous Lyman-alpha nebula' (ELAN), it is the brightest and among the largest of these rare objects, only a handful of which have been observed.

Tiny cavefish may help humans evolve to require very little sleep
We all do it; we all need it -- humans and animals alike. Neuroscientists have been studying Mexican cavefish to provide insight into the evolutionary mechanisms regulating sleep loss and the relationship between sensory processing and sleep. They are investigating how sleep evolves and using this species as a model to understand how human brains could evolve to require very little sleep, just like the cavefish.

Light-driven reaction converts carbon dioxide into fuel
Duke University researchers have developed tiny nanoparticles that help convert carbon dioxide into methane using only ultraviolet light as an energy source. Having found a catalyst that can do this important chemistry using ultraviolet light, the team now hopes to develop a version that would run on natural sunlight, a potential boon to alternative energy.

Low snowpacks of 2014, 2015 may become increasingly common with warmer conditions
Oregon experienced very low snowpack levels in 2014 and historically low snowpack levels in 2015; now a new study suggests that these occurrences may not be anomalous in the future and could become much more common if average temperatures warm just two degrees (Celsius).

Widely accepted vision for agriculture may be inaccurate, misleading
'Food production must double by 2050 to feed the world's growing population.' This truism has been repeated so often in recent years that it has become widely accepted among academics, policymakers and farmers, but now researchers are challenging this assertion and suggesting a new vision for the future of agriculture.

Birds of a feather mob together
Dive bombing a much larger bird isn't just a courageous act by often smaller bird species to keep predators at bay. It also gives male birds the chance to show off their physical qualities in order to impress females. This is according to a study, led by Filipe Cunha, in Springer's journal Behavioral Ecology and Sociobiology on predator mobbing behavior of birds where potential prey approach and harass would-be predators such as owls.

First trace of differences between matter and 'ordinary' antimatter
The world around us is mainly constructed of baryons, particles composed of three quarks. Why are there no antibaryons, since just after the Big Bang, matter and antimatter came into being in exactly the same amounts? A lot points to the fact that after many decades of research, physicists are closer to the answer to this question. In the Large Hadron Collider beauty (LHCb) experiment the first trace of the differences between baryons and antibaryons has just been encountered.
