Free-swimming Ocean Gliders Help Scientists Understand Storm Intensity
A regional team from Woods Hole Oceanographic Institution (WHOI), Rutgers University, the University of Maine, the University of Maryland, and the Gulf of Maine Research Institute mobilized Friday in advance of post-Tropical Storm Hermine’s arrival in the Northeast to gather data from new ocean instruments that will help better predict the intensity and evolution of…

Air Pollution: The Billion Dollar Industry
The World Bank has released a new report highlighting the fact that air pollution costs world governments billions upon billions every year and ranks among the leading causes of death worldwide.The estimates — drawn from a number of sources, including the World Health Organization’s most recently completed data sets compiled in 2013 — can for the first time…

Carbon-coated iron catalyst structure could lead to more-active fuel cells
Fuel cells have long held promise as power sources, but low efficiency has created obstacles to realizing that promise. Researchers at the University of Illinois and collaborators have identified the active form of an iron-containing catalyst for the trickiest part of the process: reducing oxygen gas, which has two oxygen atoms, so that it can…

Healthcare costs for infections linked to bacteria in water supply systems are rising
A new analysis of 100 million Medicare records from U.S. adults aged 65 and older reveals rising healthcare costs for infections associated with opportunistic premise plumbing pathogens–disease-causing bacteria, such as Legionella–which can live inside drinking water distribution systems, including household and hospital water pipes.A team led by researchers from the Friedman School of Nutrition Science…

Calculating the role of lakes in global warming
As global temperatures rise, how will lake ecosystems respond? As they warm, will lakes — which make up only 3 percent of the landscape, but bury more carbon than the world's oceans combined — release more of the greenhouse gases carbon dioxide and methane? And might that create a feedback loop that leads to further…

Scientists expect to calculate amount of fuel inside Earth by 2025
Earth requires fuel to drive plate tectonics, volcanoes and its magnetic field. Like a hybrid car, Earth taps two sources of energy to run its engine: primordial energy from assembling the planet and nuclear energy from the heat produced during natural radioactive decay. Scientists have developed numerous models to predict how much fuel remains inside…

Study Discovers Air Pollution Particles in the Human Brain
A new study from Lancaster University has discovered toxic nanoparticles from air pollution in large quantities in human brains. The researchers examined brain tissue from 37 people aged between 3 and 92 years old in the U.K. and Mexico. Magnetite, a type of iron oxide, was found in massive quantities in the samples – millions of particles per gram…

Increased ocean acidification is due to human activities, say scientists
Oceanographers from MIT and Woods Hole Oceanographic Institution report that the northeast Pacific Ocean has absorbed an increasing amount of anthropogenic carbon dioxide over the last decade, at a rate that mirrors the increase of carbon dioxide emissions pumped into the atmosphere.The scientists, led by graduate student Sophie Chu, in MIT's Department of Earth, Atmospheric,…

Tropics told to ban coral-killing sunscreen
Tropical island nations should team up to ban coral-killing sunscreen products, following the example of Hawaii, a conference has heard. Chemical compounds in sunscreen lotions cause irreparable damage to reefs, which are crucial to the livelihoods of 500 million people in the tropics, scientist and policymakers said at the IUCN World Conservation Congress on 3 September.…

Future fisheries can expect $10 billion revenue loss due to climate change
Global fisheries stand to lose approximately $10 billion of their annual revenue by 2050 if climate change continues unchecked, and countries that are most dependent on fisheries for food will be the hardest hit, finds new UBC research.Climate change impacts such as rising temperatures and changes in ocean salinity, acidity and oxygen levels are expected…
