Social media photos priceless for natural resources research

Tapping into social media posts on Instagram, Flickr and Panoramio gave researchers a trove of information about people’s opinions of scenic European landscapes. A new study shows that geotagged photos – complete with millions of comments – can provide data for predictive models to help guide land use policy, conservation planning and development decisions worldwide.

In communicating wildlife conservation, focus on the right message

If you want people to care about endangered species, focus on how many animals are left, not on the chances of a species becoming extinct, according to a new study.

Catalog of known near-Earth asteroids tops 15,000

The number of discovered near-Earth asteroids (NEAs) now tops 15,000, with an average of 30 new discoveries added each week. The number of discovered near-Earth asteroids (NEAs) now tops 15,000, with an average of 30 new discoveries added each week. This milestone marks a 50 percent increase in the number of known NEAs since 2013, when discoveries reached 10,000 in August of that year. Surveys funded by NASA's Near Earth Object (NEO) Observations Program (NEOs include both asteroids and comets) account for more than 95 percent of discoveries so far. The 15,000th near-Earth asteroid is designated 2016 TB57. 2016 TB57 is a rather small asteroid -- about 50 to 115 feet (16 to 36 meters) in size -- that will come closest to Earth on Oct. 31 at just beyond five times the distance of the moon. It will safely pass Earth.

Drones take off in plant ecological research

Long-term, broad-scale ecological data are critical to plant research, but often impossible to collect on foot. Traditional data-collection methods can be time consuming or dangerous, and can compromise habitats that are sensitive to human impact. Micro-unmanned aerial vehicles (UAVs), or drones, eliminate these data-collection pitfalls by flying over landscapes to gather unobtrusive aerial image data.

See how Arctic sea ice is losing its bulwark against warming summers

Arctic sea ice, the vast sheath of frozen seawater floating on the Arctic Ocean and its neighboring seas, has been hit with a double whammy over the past decades: as its extent shrunk, the oldest and thickest ice has either thinned or melted away, leaving the sea ice cap more vulnerable to the warming ocean and atmosphere.

Helping dam north of Grand Canyon balance environment, hydropower needs

Researchers have helped develop a plan for the operation of Glen Canyon Dam in Glen Canyon National Recreation Area, upstream of Grand Canyon National Park. The plan, known as the Glen Canyon Dam Long-Term Experimental and Management Plan, and documented in a final environmental impact statement, recommends a strategy that would balance hydropower with the protection of environmental, cultural and recreational resources in the area.

New research on bats hunting in noise

Noise pollution, according to a new study, has been linked to lower survival and reproduction because it masks environmental cues and makes it hard for animals to hear moving prey or approaching predators.

Colorado River’s dead clams tell tales of carbon emission

Scientists have begun to account for the topsy-turvy carbon cycle of the Colorado River delta – once a massive green estuary of grassland, marshes and cottonwood, now desiccated dead land.

Underfed worms program their babies to cope with famine

Going hungry at an early age can cause lifelong health problems. But the extent of malnutrition's damage depends on mom's diet too -- at least in worms. A new study of the tiny nematode worm C. elegans finds that young worms that don't get anything to eat in the first few days of life are buffered from early starvation's worst effects if their mothers had also been underfed.

Early Pacific seafarers likely latched onto El Nino, other climate patterns

Researchers employed computer simulations and climatic data to help them explore the travels that led to the settlement of islands in Remote Oceania.
