A group of Mexican engineers have created technology to recover and purify, either seawater or wastewater from households, hotels, hospitals, commercial and industrial facilities, regardless of the content of pollutants and microorganisms in, incredibly, just 2.5 minutes.
A tissue-thin, food-grade film acts like a raincoat for sweet cherries, cutting rain-related...
Scientists have discovered a way to make trees grow bigger and faster, which could increase...
The unassuming piece of stainless steel mesh doesn’t look like a very big deal, but this new material could make a big difference for future environmental cleanups. Water passes through the mesh but oil doesn’t, thanks to a nearly invisible oil-repelling coating on its surface.
Monitoring Europe’s vast nature protection areas used to be extremely difficult. Thanks to computer algorithms, this can now be done using aircraft and laser technology.
Researchers seeking better efficiency for cars quickly determined that cooling in direct proximity to the body provided the most efficient alternative to normal air conditioning. In contrast to previously deployed solutions, in which the entire interior is cooled or heated to the same temperature, heat is generated or dissipated only where it can actually be felt by the passengers.
Scientists have found a key ingredient in aspirin and anti-pimple products, salicylic acid, is a cost-effective plant growth and survival improver during a world-first desert restoration trial in Saudi Arabia.
Fisheries managers have decided to call off the West Coast sardine fishing season that starts in July because of rapidly dwindling numbers, hoping to save an iconic industry from the kind of collapse that hit in the 1940s and lasted 50 years.
A week shy of the fifth anniversary of the Deepwater Horizon oil spill, the Obama administration proposed new regulations aimed at strengthening oversight of offshore oil drilling equipment and ensuring that out-of-control wells can be sealed in an emergency.
A technology has the potential to revolutionize the sourcing of renewable energy from rivers. A software app automatically selects appropriate locations in rivers to site a large range of micro renewable hydro-power turbines and determines the environmental sensitivity of the location.
Researchers have discovered how communities of beneficial bacteria form a waterproof coating on the roots of plants, to protect them from microbes that could potentially cause plant disease. The insight could lead to ways to control this shield and improve its efficiency, which could help curb the risk of unwanted infections in agricultural or garden plants.
EPFL’s Energy Center has developed an information platform on energy transition. In particular, it proposes a national energy calculator to develop scenarios for Switzerland’s energy future.
Frozen Arctic and sub-Arctic soil that thaws from global warming will add substantial amounts of carbon to the atmosphere in the form of greenhouse gases, accelerating climate change the rest of the century, but it won't come in a sudden burst, researchers say in a new paper.
Invertebrates perform essential functions for the smooth running of the ecosystems in tropical forests. Nearly a half of all tropical rainforests worldwide have been logged, and this often causes heavy changes to the number and type of invertebrates, with many species being lost from the ecosystem.
Shawn Seipler is on a mission to save lives with soap. It began about seven years ago as a tiny operation in a garage in Orlando, Florida, where he and friends used meat grinders, potato peelers and cookers to recycle used soap into fresh bars. The effort has since grown to include industrial recycling facilities in cities where hotels are plentiful and used bars of soap can be gathered easily by the thousands.
What we eat has a big influence on our environment, in ways beyond the typical carbon footprint questions of local vs. imported or animal vs. vegetable. Researchers have found that what we choose to eat– and what we excrete as waste– can influence the nutrient cycle on a large scale.
Traffic fumes, dirty air blown in from Europe and Sarahan dust are combining to coat parts of Britain in smog. The environment department says air pollution is "high" across much of the country Friday and could reach the top designation of "very high" in southeast England.
California saw a record number of deaths from the West Nile virus last year, and the state's drought may have contributed to the spike in infections. Thirty-one infected people died in 2014, the most since California began recording West Nile cases in 2003.
The dispersant used to remediate the 2010 Deepwater Horizon oil spill in the Gulf of Mexico is more toxic to cold-water corals than the spilled oil, according to a study. The study comes just before the spill’s fifth anniversary, on April 20.
Figuring out why the French have low cardiovascular disease rates despite a diet high in saturated fats has spurred research and many theories to account for this phenomenon known as the “French paradox.” Most explanations focus on wine and lifestyle, but a key role could belong to another French staple: cheese.
NASA has licensed patents on high-temperature thermoelectric materials that convert heat into electricity. For example, by using this technology, waste-heat from a car could potentially be fed back into the vehicle and used to generate electricity.
Several members of Congress are heading to the mothballed site of a proposed radioactive waste dump in the Nevada desert amid new talk about a decades-old problem— where to dispose of spent nuclear fuel stored at commercial reactors around the U.S.
Now that most consumers download and stream their movies and music, more and more CDs and DVDs will end up in landfills or be recycled. But soon these discarded discs could take on a different role: curbing the release of greenhouse gases.
When carbonate samples from One Tree Reef in southern Great Barrier Reef arrived at ANSTO for radiocarbon dating, a researcher was confident they could accurately determine the age of the marine material. He did not anticipate that the samples would provide surprising evidence that a small fall in sea level significantly slows down the growth of the reef.
Is it worth having birds in the city? If you live in Seattle or Berlin, the answer is yes, to the tune of $120 million and $70 million a year for each city, respectively.
A team of scientific investigators is now in the Four Corners region of the U.S. Southwest, aiming to uncover reasons for a mysterious methane hotspot detected from space by a European satellite. The joint project is working to solve the mystery from the air, on the ground and with mobile laboratories.
The gases used to knock out surgery patients are accumulating in the Earth’s atmosphere, where they make a small contribution to climate change, report scientists who have detected the compounds as far afield as Antarctica. Over the past decade, concentrations of the anesthetics desflurane, isoflurane and sevoflurane have been rising globally, the new study finds.
A call for action, resulting from last summer’s Lake Erie toxic algae outbreak that shut down the water supply for almost half a million people, focused on setting toxin standards and reducing discharges of the fertilizer phosphorus. This is a rational and appropriate response. But, truly addressing a problem of this scale requires cutting back on industrial corn farming— which means reexamining our agricultural, food and energy policies.
