Elevated carbon dioxide concentrations in the atmosphere may increase water-use efficiency in crops and considerably mitigate yield losses due to climate change, according to a new NASA study.

The results, published in the journal Nature Climate Change on April 18, 2016 show some compensation for the adverse impacts of temperature extremes and water scarcity caused by increasing emissions of carbon dioxide and other greenhouse gases.

Offering virtual dermatology care to Medicaid recipients can sharply increase use of dermatology services, offering one potential way to increase access to medical specialists who are in short supply, according to a new RAND Corporation study.

Researchers found that after the introduction of a teledermatology service, the number of patients who received care from a dermatologist nearly doubled, with greater utilization of dermatology care among patients treated in primary care practices that began using the service, as compared to patients seen by primary care practices that did not use the teledermatology service.

For many fans around the world May 4th is Star Wars Day, playing on the popular phrase 'May the Force Be With You' uttered by many characters in the films including Luke Skywalker's mentor, Yoda.

However, despite his esteemed position as a Jedi Master in the Star Wars universe, Yoda may have struggled to pull off some of his trickier Force-related feats due to lack of energy, according to students from the University of Leicester.

In the Star Wars cinematic series 'the Force' is used in the universe to accomplish great feats of strength, agility and even telekinesis. The only explanation given for these abilities is that there are micro-organisms called 'midi-chlorians' living inside all living cells.

RENO - For the first time in aviation history, a fixed-wing unmanned aircraft has successfully tested a cloud-seeding payload during an experimental flight in Nevada.

Flown at Hawthorne Industrial Airport under the state's FAA (Federal Aviation Administration) Unmanned Aircraft Systems (UAS) Test Site designation, the Drone America Savant™ aircraft reached an altitude of 400 feet and flew for approximately 18 minutes on Friday, April 29, 2016.

The Savant™ aircraft -- named the "Sandoval Silver State Seeder" in honor of Governor Brian Sandoval's dedication to the success of the state's UAS industry -- deployed two silver-iodide flares, successfully testing and demonstrating its ability to perform unmanned aerial cloud seeding operations.

While there are many examples of unethical leaders, from FIFA to the recent political discoveries from the Panama Papers leak, there are countless other examples, though not as headline grabbing, in history of leaders acting morally. Recent research offers new ideas for curbing unethical behavior by those with power -- it all depends on how people in power think about their power.

"We suggest that how today's leaders and managers think about the power they wield can shape how they behave," says lead author Miao Hu (Shidler College of Business, University of Hawai'i at Manoa). "Moreover, focusing the powerful to think about how they should behave may serve as a potential form of preventative medicine against the abuse of power."

London, UK (May 04, 2016). Leaving work at the office and home at the door may not always be the best strategy for employee well-being and performance, according to a new paper in Human Relations .

Traditionally it has been thought that in order to maintain concentration and high performance, employees needed to have a strict separation between home and work - the well-traveled work-life balance claim which, like ecological balance of nature, caught on with public and journalists who know little about science, but has never been shown to be true.

The new paper follows common sense; integration across both domains reduces the impact of moving between home and work roles while also preserving employees' ability to be effective in their jobs.
