The world’s largest rivers begin in glaciated mountain regions. However, climate change may cause many glaciers to disappear. Will water become scarce?
A Duke University-led study has found dangerously high levels of mercury and its more toxic chemical cousin, methylmercury, in soils, sediments and rivers near artisanal gold mines in the West African nation of Senegal.
A new study examined concentrations of polycyclic aromatic hydrocarbons (PAHs) before and after Hurricane Harvey in the Houston environmental justice neighborhood of Manchester.
A seismic stress map created by Stanford geophysicists can help predict which parts of West Texas and New Mexico may be at risk of fracking-induced earthquakes. The map could guide oil discovery efforts in the region.
With their large buck teeth and wrinkled, hairless bodies, naked mole rats won’t be winning any awards for cutest rodent. But their long life span—they can live up to 30 years, the longest of any rodent—and remarkable resistance to age-related diseases, offer scientists key clues to the mysteries of aging and cancer.
Some calves are inherently optimistic or pessimistic, just as humans are, a new University of British Columbia study has found.
Recognizing these individual personality differences is important to ensure animals are treated well, says professor Marina von Keyserlingk, who led the research team from UBC’s animal welfare program in the faculty of land and food systems.
Removing fossil fuel subsidies would have only a small effect on CO2 emissions and renewable energy use, new research has shown. The largest emissions savings would be in oil and gas exporting countries, where fewer poor people would be affected, and subsidy removal can be aided by currently low oil prices.
Pine trees become temporarily sterile when exposed to ultraviolet radiation as intense as some scientists believe the Earth experienced 252 million years ago during the planet’s largest mass extinction, lending support to the theory that ozone depletion contributed to the crisis.
Study finds cleaner ship fuels will reduce childhood asthma by 3.6 percent globally
Storing carbon dioxide (CO2) deep below the seabed is one way to counteract the increasing concentration of CO2 in the atmosphere. But what happens if such storage sites begin to leak and CO2 escapes through the seafloor? Answers to this question have now been provided by a study dealing with the effects of CO2 emissions on the inhabitants of sandy seabed areas.
