Researchers writing in Microchemical Journal are bringing attention to the fact that commonly used antibiotic drugs are making their way out into the environment, where they can harm microbes that are essential to a healthy environment. Their review article has been selected for the Elsevier Atlas Award, which recognizes research that could significantly impact people's lives around the world or has already done so.
For nearly a century, the O'Shaughnessy seawall has held back the sand and seas of San Francisco's Ocean Beach. At work even longer: the Galveston seawall, built after America's deadliest hurricane in 1900 killed thousands in Texas.
Geoengineering is a catch-all term that refers to various theoretical ideas for altering Earth's energy balance to combat climate change. New research from an international team of atmospheric scientists published by Geophysical Research Letters investigates for the first time the possibility of using a 'cocktail' of geoengineering tools to reduce changes in both temperature and precipitation caused by atmospheric greenhouse gases.
Scientists from Tomsk Polytechnic University and the University of Chemistry and Technology (Prague, Czech Republic) have created novel chemical sensors for Raman spectrometers. Having combined physical and chemical methods scientists obtained highly sensitive sensors for determining dyes prohibited in Europe and heavy metals in water at ultralow concentrations. The process of analysis lasts a couple of minutes, so the sensors are appropriate for using in mobile laboratories.
Everyone knows that exposure to pollution during rush hour traffic can be hazardous to your health, but it's even worse than previously thought. In-car measurements of pollutants that cause oxidative stress found exposure levels for drivers to be twice as high as previously believed.
Industrial ecologist Roland Geyer measures the production, use and fate of all the plastics ever made, including synthetic fibers.
Whales, sharks, butterflies and lotus leaves might together hold the secret to saving the shipping industry millions and help save the planet, according to a marine biologist at the University of Portsmouth, UK.
An interdisciplinary team of researchers found that they could slow deforestation and preserve endangered chimpanzee habitats by paying poor landowners in Uganda not to cut down trees on their property. The system of small payments effectively cut deforestation in half, keeping the average equivalent of 3,000 metric tons of CO2 out of the air for every village who participated. The program was also cost-effective: it was 10 to 50 times cheaper than many pollution-fighting measures in the US.
When it comes to the current plans to retire US power plants, Carnegie Mellon University researchers believe we are 'running towards a cliff with no fence.' They found that power plant retirement trends will complicate achieving long-term carbon dioxide emission reduction targets and require a significant increase in capital investments.
Humans have created 8.3 billion metric tons of plastics since large-scale production of the synthetic materials began in the early 1950s, and most of it now resides in landfills or the natural environment, according to a study published today in the journal Science Advances.
