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.

The changes that the Amazon River promotes in the tropical North Atlantic ocean water make an unfavorable environment for reef development. Every second, 175 million liters of water mixed with sediments are brought to the ocean. The result is low sunlight penetration, variability in nutrient concentration, salinity and pH, extensive moody bottoms and significant changes in temperature and oxygenation levels towards the bottom - conditions not associated with reefs. The plume generated by the Amazon River has 1.3 million km2 and flows mostly to the North, reaching areas as far as the Caribbean Sea.

It's a weekday morning, and senior Reuben Brough is running around a gym at King Street Youth Center waving his hands in the air and screeching like a cheetah. A stream of children is in hot pursuit of him and four other UVM students who implore the preschoolers to "catch the cheetah."

It looks like total chaos as Brough, now a shark, yells "fishies, fishes cross my ocean," daring the children to run past him at half court. But there's a method to the madness, which is really a highly structured, research-based fitness program designed by Betsy Hoza, Bishop Joyce Chair of Human Development and professor of psychological science, called Children and Teachers (CATs) on the Move.

By switching from four wheels to two, bicyclists help reduce traffic and air pollution -- all while getting much-needed exercise. But that health benefit could be costly, due to exposure to potentially harmful compounds in motor vehicle exhaust. In a first-of-its-kind study, researchers analyzed breath samples to find out how much of these compounds are absorbed by the body. They report their findings in ACS' Environmental Science & Technology.

Galileo is regarded as an important figure today, because he was put under house arrest by his church for ridiculing the Pope, but for much of his career he was derided by other scientists. Both Kepler and mathematics knew Galileo was wrong about the moon, for example, but his flavor of science insisted that the tides only happened once per day if they happened at all, they happened at the same time every day, and that Luna had nothing to do with them.

Alexandria, VA (May 4, 2016) -- Three-quarters of Americans are concerned about potential eye problems from the sun's ultraviolet rays, yet only 31 percent protect their eyes with sunglasses or other UV-protective eyewear every time they go outside, according to a new nationwide survey released today. The report by The Vision Council, based on a survey of more than 10,000 adults, finds 34 percent of adults have experienced symptoms of prolonged UV exposure, such as eye irritation, trouble seeing, and red or swollen eyes.

Persons with the serious disorder ALS, can have a genetic mutation that causes the protein SOD1 to aggregate in motor neurons in the brain and spinal cord. Researchers at Umeå University have discovered that, when injected into mice, the SOD1 aggregation spreads rapidly leading to ALS. The discovery has been described in the Journal of Clinical Investigation.

ALS, Amyotrophic lateral sclerosis, is a disorder which causes death of motor neurons in the brain and the spinal cord in charge of controlling muscles. This leads to progressive paralysis and death, often due to carbon dioxide narcosis.

The oldest surviving species of vertebrates, such as the cane toad and the California sea lion, which have endured past extreme environmental events, will be more likely to adapt to future climate changes than younger species, such as the European hamster, according to a study published in the open access journal BMC Evolutionary Biology. These species include those with various color morphs; those which give birth to live young; and/or which live at low latitudes.
