A long-term study of more than 500 children who grew up in the era of leaded gasoline has shown that their exposure to the powerful neurotoxin may have led to a loss of intelligence and occupational standing by the time they reached age 38. The effects are slight, but significant, showing that the higher the
A type of bacteria accidentally discovered during research supported by the Engineering and Physical Sciences Research Council (EPSRC) could fundamentally re-shape efforts to cut the huge amount of electricity consumed during wastewater clean-up. The discovery has upended a century of conventional thinking. The microorganisms - 'comammox' (complete ammonia oxidising) bacteria - can completely turn ammonia
Unprecedented summer warmth and flooding, forest fires, drought and torrential rain — extreme weather events are occurring more and more often, but now an international team of climate scientists has found a connection between many extreme weather events and the impact climate change is having on the jet stream. "We came as close as one
Nearly 1,000 feet below the bed of the Dead Sea, scientists have found evidence that during past warm periods, the Mideast has suffered drought on scales never recorded by humans—a possible warning for current times. Thick layers of crystalline salt show that rainfall plummeted to as little as a fifth of modern levels some 120,000
A new disposable battery that folds like an origami ninja star could power biosensors and other small devices for use in challenging field conditions, a Binghamton University engineer says. Seokheun “Sean” Choi and two of his students developed the device, a microbial fuel cell that runs on the bacteria available in a few drops of
In 2015, Google launched Project Sunroof, a map that shows which houses have enough sun exposure for solar panels to be a viable energy source. However, the original map was very limited, covering only the San Francisco Bay Area, Fresno, California and Boston. Now, Google has greatly expanded the project to cover all 50 U.S.
According to an October 2016 Pew poll, only about half of Americans believe that climate change is due to human activity. The U.S. remains home to a considerable number of “climate skeptics,” who clearly impact the politics around the issue, as they are unlikely to support costly actions such as carbon taxes intended to mitigate
Nearly 25 percent of the world’s malnourished population lives in sub-Saharan Africa, where more than 300 million people depend on corn, or maize, as their main food source. Maize is the most widely harvested agricultural product in Africa and is grown by small farmers who rely heavily on rainwater rather than irrigation. The crop is
GreenWish Partners, a Paris-based independent power producer, will invest $280 million to build solar-power plants in Nigeria that are expected to start producing electricity in the first quarter of next year. A plant in the southeastern state of Enugu will produce 100 megawatts, while the company will build two others of 50 megawatts each in
With the first day of spring around the corner, temperatures are beginning to rise, ice is melting, and the world around us is starting to blossom. Scientists sometimes refer to this transition from winter to the growing season as the “vernal window,” and a new study led by the University of New Hampshire shows this
The greatest challenge for mankind in the 21st century is powering the planet, while at the same time drastically reducing carbon emissions and continuing to lower the cost of energy. One year ago, GE published a Ecomagination report that examined the incredible acceleration of renewable energy development across the globe. We called upon businesses, investors and governments
Across the world, myriad efforts are underway to make energy systems cleaner, smarter, and more efficient. But it’s hard to get a sense of the total size of those efforts, as they are spread across so many different industries and regions. One organization that has given this quite a bit of thought is Advanced Energy
“Citizen scientists,” or members of the public who voluntarily engage in scientific work, already contribute a great deal to environmental science, but they still have the potential to do much more for regional and global assessments of biodiversity, says a study published in the journal Biological Conservation (3 November). “We have seen a wide range
An international team of scientists led by Liang-shi Li at Indiana University has achieved a new milestone in the quest to recycle carbon dioxide in the Earth’s atmosphere into carbon-neutral fuels and others materials. The chemists have engineered a molecule that uses light or electricity to convert the greenhouse gas carbon dioxide into carbon monoxide
Scientists made a surprising discovery on their mission to find better indicators for impending volcanic eruptions: it looks like tree rings may be able to predict eruptions, report the Swiss Federal Institute for Forest, Snow and Landscape Research WSL and the ETH Zurich. Nicolas Houlié, a geophysicist at ETH Zurich, first came to know about
"Many people may not realize that volcanoes are continuously releasing quite large amounts of gas, and may do so for decades or even centuries," says volcanologist Simon Carn, an associate professor at Michigan Tech in Houghton, Michigan, and the lead author of the new study. "Because the daily emissions are smaller than a big eruption,
Earth has known several mass extinctions over the course of its history. One of the most important happened at the Permian-Triassic boundary 250 million years ago. Over 95% of marine species disappeared and, up until now, scientists have linked this extinction to a significant rise in Earth temperatures. But researchers from the University of Geneva
Cinder-block walls still bear Day-Glo paint murals inside the former laser tag arena that once hosted epic battles among New Jersey teens who breathlessly chased each other in a high-tech version of the incredibly low-tech game of tag. Nowadays, AeroFarms has taken over the cavernous building to operate one of the country’s biggest vertical farms.
Researchers at Caltech and Lawrence Berkeley National Laboratory (Berkeley Lab) have—in just two years—nearly doubled the number of materials known to have potential for use in solar fuels. They did so by developing a process that promises to speed the discovery of commercially viable solar fuels that could replace coal, oil, and other fossil fuels.
Some electronic energy meters can give false readings that are up to 582% higher than actual energy consumption. This emerged from a study carried out by the University of Twente (UT), in collaboration with the Amsterdam University of Applied Sciences (AUAS). Professor Frank Leferink of the UT estimates that potentially inaccurate meters have been installed
