Switchable DNA mini-machines store information
Biomedical engineers have built simple machines out of DNA, consisting of arrays whose units switch reversibly between two different shapes. The arrays' inventors say they could be harnessed to make nanotech sensors or amplifiers. Potentially, they could be combined to form logic gates, the parts of a molecular computer.

New efficient, low-temperature catalyst for hydrogen production
Scientists have developed a new low-temperature catalyst for producing high-purity hydrogen gas while simultaneously using up carbon monoxide (CO). The discovery could improve the performance of fuel cells that run on hydrogen fuel but can be poisoned by CO.

Pollinator extinctions alter structure of ecological networks
The absence of a single dominant bumblebee species from an ecosystem disrupts foraging patterns among a broad range of remaining pollinators in the system -- from other bees to butterflies, beetles and more, field experiments show.

African leopards revealed: Study documents minute-to-minute behavior of elusive cats
The elusive behavior of the African leopard has been revealed in great detail for the first time as part of a sophisticated study that links the majestic cat's caloric demands and its drive to kill.

New IST research leverages big data to predict severe weather
Every year, severe weather endangers millions of people and causes billions of dollars in damage worldwide. But new research from Penn State's College of Information Sciences and Technology (IST) and AccuWeather has found a way to better predict some of these threats by harnessing the power of big data.

When lovers touch, their breathing and heartbeat syncs, pain wanes, study shows
A new study by pain researchers from University of Colorado and University of Haifa found that when an empathetic partner holds a lover's hand, their heart rates and breathing rates sync and her pain subsides. Authors say such 'interpersonal synchronization' could play a role in the analgesic impacts of touch.

Study finds most people aren't as happy as their friends on social media
A study led by computer scientists at Indiana University has found that people with the most connections on social media are also happier. This may cause most social media users to not only regard themselves as less popular than their friends but also less happy.

Board game helps Mexican coffee farmers grasp complex ecological interactions
A chess-like board game developed by University of Michigan researchers helps small-scale Mexican coffee farmers better understand the complex interactions between the insects and fungi that live on their plants -- and how some of those creatures can help provide natural pest control.

Corn better used as food than biofuel, study finds
Corn is grown not only for food, it is also an important renewable energy source. Renewable biofuels can come with hidden economic and environmental issues, and the question of whether corn is better utilized as food or as a biofuel has persisted since ethanol came into use. For the first time, researchers at the University of Illinois have quantified and compared these issues in terms of economics of the entire production system to determine if the benefits of biofuel corn outweigh the costs.

Mountain lions fear humans, fleeing when they hear our voices, new study reveals
New research into the behavior of mountain lions indicates they don't like encountering humans any more than we like bumping into them on hiking trails. The findings are particularly valuable as human development encroaches on lion habitat and drives up the number of human-puma encounters.

Wet and stormy weather lashed California coast... 8,200 years ago
An analysis of stalagmite records from White Moon Cave in the Santa Cruz Mountains shows that 8200 years ago the California coast underwent 150 years of exceptionally wet and stormy weather. This is the first high resolution record of how the Holocene cold snap affected the California climate.

Students of all races & ethnicities benefit from ethnically diverse middle schools
More than half of school-age youth in the United States are members of ethnic minority groups, yet the nation's public schools are becoming less ethnically diverse. Recognizing these conflicting trends and the lack of research on the effects of ethnic diversity, a new study sought to determine how the diversity of middle school students and classrooms shapes students' self-reported well-being and their views on race.

Is it sometimes ok to cheat?
When both partners benefit from a relationship -- husband and wife or pollinator and flower -- the relationship is known as a mutualism. Sometimes partners do not deliver their side of the bargain while still reaping the rewards. Research done at the Smithsonian in Panama published shows that unless unfaithful partners are severely punished by the other member of the relationship cheaters may become more common.

Freshwater from salt water using only solar energy
A federally funded research effort to revolutionize water treatment has yielded a direct solar desalination technology that uses energy from sunlight alone to heat salt water for membrane distillation. The technology could provide off-grid water treatment for some of the 1 billion people who lack access to clean water.

Each year, more than a million wildebeest migrate through Africa's Serengeti Mara Ecosystem. While crossing the Kenyan reach of the Mara River, thousands perish. A new study, published today in the Proceedings of the National Academy of Sciences, is the first to reveal how wildebeest drownings impact the ecology of the iconic river.
