Comments Off on Bio-inspired membrane captures 90% of CO2 in power plant emissions

Researchers at Sandia National Laboratories have developed a new biologically inspired membrane that can capture carbon dioxide from power plant smoke. Sandia fellow and University of New Mexico regents’ professor Jeff Brinker said, “Our inexpensive method follows nature’s lead in our use of a water-based membrane only 18 nanometers thick that incorporates natural enzymes to capture 90 percent of carbon dioxide released. This is almost 70 percent better than current commercial methods, and it’s done at a fraction of the cost.” Brinker said that, in the past, it has been prohibitively expensive to remove CO2 from coal smoke with available polymer membranes. However, his team’s membrane boasts a “relatively low cost of $40 per ton.” The researchers call the membrane a ‘memzyme’ because it operates like a filter but is near-saturated with carbonic anhydrase, an enzyme “developed by living cells over millions of years to help rid themselves of carbon dioxide efficiently and rapidly.” University of New Mexico professor Ying-Bing Jiang came up with the concept of employing watery membranes, inspired by processes in the human body that separate out CO2. Brinker said the arrangement of the membrane inside the flue of a generating station would be similar to a catalytic converter in a car.

In addition, the membranes have worked efficiently for months in laboratory settings.

Climate change could reverse all reductions in child mortality over the last 25 years

Comments Off on Climate change could reverse all reductions in child mortality over the last 25 years

Kids could be especially vulnerable to climate change -related health risks, and a new American Academy of Pediatrics (AAP) article once again sounds the alarm. The authors say climate change “threatens to reverse the gains in global child health and the reductions in global child mortality made over the past 25 years.” While the impacts of climate change could be felt by all humans, the authors say they’ll be disproportionally felt by poor people and children . 88 percent of diseases attributable to climate change appear in kids under five, according to the World Health Organization. The new paper delves into studies about how climate change could impact children’s health and calls for better preparation. CNN cited paper co-author and Memorial University pediatrics chairman Kevin Chan as saying weather events tied to climate change that have impacted kids’ health include Hurricanes Harvey or Irma . Pathogens like the Zika virus or extreme heat could also put children’s health at risk. Related: AAP warns of the impact of global warming on children’s health Chan told CNN he, along with the paper’s other author Rebecca Pass Philipsborn of the Emory University School of Medicine , aimed to reveal “there’s very little research and evidence around children. A lot of the research is very, very broad and tends to look more at adult populations. I don’t think they factor in the specific impacts on children themselves, and I think more research is needed in that arena.” Medical Society Consortium on Climate and Health executive director Mona Sarfaty, who wasn’t involved in this new AAP article, told CNN, “The danger to children is real and is already witnessed by physicians in the US…They are more vulnerable to the heat-related increases in air pollution that come from fossil fuel exhaust, because their lungs are still developing. Outdoor play also makes them more prey to insect vectors carrying dangerous infections.” Chan told CNN, “We really need more efforts into addressing climate change to protect our children.” + American Academy of Pediatrics Via CNN Images via Pixabay and Eoghan Rice/Trócaire via Trocaire on Flickr

11-year-old discovers rare 475-million-year-old fossil in Tennessee

Comments Off on 11-year-old discovers rare 475-million-year-old fossil in Tennessee

While enjoying an evening walk at Douglas Lake in East Tennessee , 11-year-old Ryleigh Taylor stumbled upon a magnificent discovery: the 475-million-year-old fossilized remains of an ancient sea creature called a trilobite. Taylor brought her find to the University of Tennessee , where it was examined by paleobiology professor Colin Sumrall. “Typically when we look at fossils of trilobites, they molt when they grow,” Sumrall told WATE.com . “So what happens is, when the trilobite skeleton just crumbles into hundreds of little pieces. To find one where all the pieces are intact, it’s actually a pretty lucky find.” Related to modern crustaceans, spiders and insects , most closely to horseshoe crabs, trilobites were a widespread arthropod group during the Cambrian period, reaching 60 different species at its peak. The group began to shrink during the Devonian period, then eventually went extinct in the wake of the Permian extinction. Named trilobite for its “three-lobes” body structure, the group is thought to be one of the first organisms to experience vision. While some trilobites could not have been seen without a microscope, others, such as isotelus rex , could grow to be several feet in length. Related: Treasure trove of Triassic fossils found at Bears Ears Taylor was thrilled with her discovery. “To find something like that, it’s really really cool,” Taylor told WATE . “I looked down while I was walking and I found it, I just saw it.” Taylor hopes that her unexpected fossil find will inspire other young people to get outside and explore. “I can show kids that are my age that they don’t have to sit inside and play games . They can actually go outside and find different things,” said Taylor. “To find something like that, it could spark this youngster into a whole career,” explained Sumrall. “Maybe she’ll become a great paleontologist one day.” For now, Ryleigh Taylor is simply content to continue exploring.

Comments Off on Scientists Make Fuel from CO2 Emissions and Sunlight

Scientists from Sandia National Labs have successfully field-tested a machine that uses solar energy to convert CO 2 waste from power plants into fuels such as gasoline, diesel, and jet fuel. Cylindrical in shape, the device has both a hot and cold chamber with 14 Frisbee-like rings in the middle.
