Saving Nemo: Bleaching threatens clownfish
Published May 27, 2016 - 9:26:23 AM
Clownfish became a household name over a decade ago when Disney released the movie "Finding Nemo."
Found exclusively in the Indo-Pacific, clownfish are symbiotic animals that only live in sea anemones, a close relative of corals that don't have a hard outer shell. The anemone provides a home and protection for the clownfish, while the clownfish provides food for the anemone.

Study shows how air pollution fosters heart disease
Published May 25, 2016 - 8:23:48 AM
Long-term exposure to air pollution has been linked to an increased risk of heart disease, but the biological process has not been understood. A major, decade-long study of thousands of Americans found that people living in areas with more outdoor pollution -- even at lower levels common in the United States -- accumulate deposits in the arteries that supply the heart faster than do people living in less polluted areas.
USGS: New research confirms continued, unabated and large-scale amphibian declines

New U.S. Geological Survey-led research suggests that even though amphibians are severely declining worldwide, there is no smoking gun - and thus no simple solution - to halting or reversing these declines.
Close-up of the Red Planet
Published May 20, 2016 - 8:03:03 AM
During May 2016 the Earth and Mars get closer to each other than at any time in the last ten years. The NASA/ESA Hubble Space Telescope has exploited this special configuration to catch a new image of our red neighbour, showing some of its famous surface features. This image supplements previous Hubble observations of Mars and allows astronomers to study large-scale changes on its surface.

Biodiversity protects fish from climate change
Published May 17, 2016 - 8:43:15 AM
Fish provide protein to billions of people and are an especially critical food source in the developing world. Today marine biologists confirmed a key factor that could help them thrive through the coming decades: biodiversity. Communities with more fish species are more productive and more resilient to rising temperatures and temperature swings, according to a new study from the Smithsonian’s Tennenbaum Marine Observatories Network and other international institutions.
Why the effects of 2016 El Niño trumped climate change in the Alberta wildfires
Published May 17, 2016 - 7:23:28 AM
In the wake of the damaging Alberta fires, there has been a lot of attention paid to what role climate change plays in wildfires. Yet 2016 is also a powerful El Niño year, which has created ideal conditions for the extraordinary fires in Alberta.
Wildfires: The influence of human demographic development on fires in ecosystems is as strong as that of climate change
Published May 13, 2016 - 11:36:38 AM
Every year, about 350 million hectares of land are devastated by fires worldwide, this corresponds to about the size of India. To estimate the resulting damage to human health and economy, precise prognosis of the future development of fires is of crucial importance. Previous studies often considered climate change to be the most important factor. Now, a group of scientists, including researchers of Karlsruhe Institute of Technology (KIT), has found that population development has the same impact at least. The results are presented in the Nature Climate Change journal (dx.doi.org/10.1038/nclimate2999).
A Quasiparticle Collider
Published May 12, 2016 - 8:32:59 AM
In the early 1900s, Ernest Rutherford shot alpha particles onto gold foils and concluded from their scattering properties that atoms contain their mass in a very small nucleus. A hundred years later, modern scientists took that concept to a new level, building the Large Hadron Collider in Switzerland to smash protons into each other, which led to the discovery of the Higgs boson.

U.S. beekeepers lost 44 percent of bees in 2015-16
Published May 10, 2016 - 9:38:17 AM
Beekeepers across the United States lost 44 percent of their honey bee colonies during the year spanning April 2015 to April 2016, according to the latest preliminary results of an annual nationwide survey. Rates of both winter loss and summer loss--and consequently, total annual losses--worsened compared with last year. This marks the second consecutive survey year that summer loss rates rivaled winter loss rates.

Leftover warm water in Pacific Ocean fueled massive El Niño
Published May 9, 2016 - 9:32:48 AM
A new study provides insight into how the current El Niño, one of the strongest on record, formed in the Pacific Ocean. The new research finds easterly winds in the tropical Pacific Ocean stalled a potential El Niño in 2014 and left a swath of warm water in the central Pacific. The presence of that warm water stacked the deck for a monster El Niño to occur in 2015, according to the study’s authors.
Enceladus Jets: Surprises in Starlight

How Safe Is Your Data in the Gig Economy?
Published May 5, 2016 - 9:39:13 AM
The “sharing” or “gig” economy is booming—you can get rides with companies like Uber, hire people to run errands with services like Taskrabbit, or find a places to stay on websites like Airbnb. These companies connect people offering services to people purchasing them, and in the process they have access to vast amounts of personal data. But how well do these companies protect your information from the government? The sixth annual “Who Has Your Back” report from the Electronic Frontier Foundation (EFF) surveyed the biggest providers in the gig economy to find out.
Planet Nine: A world that shouldn't exist
Published May 4, 2016 - 10:25:21 AM
Earlier this year scientists presented evidence for Planet Nine, a Neptune-mass planet in an elliptical orbit 10 times farther from our Sun than Pluto. Since then theorists have puzzled over how this planet could end up in such a distant orbit.
Lyme disease: a ticking time bomb
Published May 4, 2016 - 8:21:51 AM
On any ranked list of nasty diseases transmitted by mosquitoes, ticks and fleas in the Western world, Borrelia burgdorferi, would have to lie near the top. These bacteria cause Lyme disease, which was first recognised in the US in the early 1970s among patients in Lyme, Connecticut. However, the oldest known case was the Tyrolean Iceman, a 5,300-year-old Copper-age mummified individual, discovered in the Italian Alps.

A recent study by researchers at the University of Hawaiʻi at Mānoa, published this month in the journal Toxins, may finally put to rest the ongoing debate about whether to use cold or heat to treat jellyfish stings. Their systematic and critical review provides overwhelming evidence that clinical outcomes from all kinds of jellyfish stings are improved following treatment with hot packs or hot-water immersion.
New Maps Chart Greenland Glaciers' Melting Risk

Many large glaciers in Greenland are at greater risk of melting from below than previously thought, according to new maps of the seafloor around Greenland created by an international research team. Like other recent research findings, the maps highlight the critical importance of studying the seascape under Greenland's coastal waters to better understand and predict global sea level rise.
Ocean Currents Push Phytoplankton -- and Pollution -- Around the Globe Faster Than Thought
Published Apr 20, 2016 - 12:26:45 PM
The billions of single-celled marine organisms known as phytoplankton can drift from one region of the world's oceans to almost any other place on the globe in less than a decade, Princeton University researchers have found.
Unfortunately, the same principle can apply to plastic debris, radioactive particles and virtually any other man-made flotsam and jetsam that litter our seas, the researchers found. Pollution can thus become a problem far from where it originated within just a few years.
Study indicates polar bears are swimming more as sea ice retreats
Published Apr 20, 2016 - 12:14:13 PM
A study undertaken by scientists from the University of Alberta and Environment and Climate Change Canada to understand swimming behavior in polar bears is showing an increase in this behavior related to changes in the amount and location of summer sea ice. Lead author Nicholas Pilfold, now a postdoctoral fellow at San Diego Zoo Global, said "the pattern of long-distance swimming by polar bears in the Beaufort Sea shows the fingerprint of climate change. Swims are occurring more often, in association with sea ice melting faster and moving farther from shore in the summer."
