Epa Moves To Count Methane Emissions From Fracking

The EPA’s Greenhouse Gas Reporting Program currently requires energy companies to report only those emissions from fracking operations that involve flaring — the industry’s practice of burning off excess natural gas at a well site. Scientists have called for a more thorough accounting of the energy industry’s greenhouse gas emissions so they can fully understand how oil and gas operations affect climate change. Many studies have shown that methane frequently leaks from oil and gas operations, but too little public information exists for researchers to know the specific sources of the emissions....

Gap Widens Between U S Climate Policy And Coal Leasing

Southern Utah is national park country—five parks spread across scenic red rock canyons and picturesque mesas. It’s also the scene of the Obama administration’s ongoing coal leasing program, which allows mining companies to produce coal on federally-owned public land. At a time when climate scientists are warning with increasing urgency that many fossil fuel resources must be left in the ground, the federal government is leasing publicly-owned land and minerals for coal mining at an increasing rate, especially in Wyoming, Colorado and Utah....

How To Build An Mrna Arsenal For Pandemic Prevention

The current COVID-19 pandemic has claimed an estimated 18.2 million lives globally1, but it could have been worse. Without vaccines, the death toll could have been closer to 40 million2. A future pandemic, set off by a putative ‘Disease X’, could be even worse, and health-care experts want to be prepared. Disease X, in this instance, is the unknown pathogen, as designated by the World Health Organization (WHO), with potential to cause a serious international epidemic....

Insect Wings Shred Bacteria To Pieces

The veined wing of the clanger cicada kills bacteria solely through its physical structure — one of the first natural surfaces found to do so. An international team of biophysicists has now come up with a detailed model of how this defense works on the nanoscale. The results are published in the latest issue of the Biophysical Journal. The clanger cicada (Psaltoda claripennis) is a locust-like insect whose wings are covered by a vast hexagonal array of ’nanopillars’ — blunted spikes on a similar size scale to bacteria (see video, bottom)....

Is America Evolving On Evolution

SA Forum is an invited essay from experts on topical issues in science and technology. For the scientific community, the release of public polls on contentious questions of science usually makes us feel like Bill Murray’s character in the film Groundhog Day. As in each repeating day in Punxsutawney, each new poll asks the same questions and gets the same discouraging answers. And news outlets produce the same stories about the large percentage of Americans who reject evolution or climate change or believe in UFOs or ghosts....

Major Ethanol Producer To Build Cellulosic Refinery In Iowa

The nation’s largest grain ethanol producer, Poet LLC, will use state and federal grants to start work on the company’s first commercial cellulosic refinery in Iowa. The Sioux Falls, S.D.-based company is preparing to convert a 50-million-gallon-a-year grain ethanol plant in Emmetsburg, Iowa, into an integrated refinery that would produce fuels from both corn kernels and cobs. “Project Liberty” would begin production in 2011 with a 125-million-gallon-a-year nameplate capacity, followed by several more dual-fuel plants throughout the state, company officials claim....

Matching Dna To A Diet Does Not Work

DNA testing won’t guide dieters to the weight-loss regimen most likely to work for them, scientists reported on Tuesday. Despite some earlier studies claiming that genetic variants predict whether someone has a better chance of shedding pounds on a low-carbohydrate or a low-fat diet, and despite a growing industry premised on that notion, the most rigorous study so far found no difference in weight loss between overweight people on diets that “matched” their genotype and those on diets that didn’t....

Tumor Mutation Burden Unlocking Cancer S Genetic Fingerprint

Cancer patients have primarily been limited to one option for care — chemotherapy — which attacks almost any cell that replicates quickly. Recently, however, predictive biomarkers have opened the door to matching patients with targeted treatments based on their unique disease biology. As objective, quantifiable measures of biological processes, biomarkers can reveal details of a patient’s disease and its progression, as well as how they might respond to treatment. Tumor mutation burden (TMB) is a measurement of the number of mutations carried by tumor cells and an emerging area of focus in biomarker research....

Warming Boosted Florence S Rainfall One Expert Says

Severe flooding during Hurricane Florence has provided new evidence that accumulating heat in the world’s oceans from climate change is bringing new dangers to the nation’s coastlines. Rising ocean energy is closely connected to the growing size of storms, the intensity of their rains and the resulting flood damage, according to scientists. Kevin Trenberth, a senior scientist at the National Center for Atmospheric Research (NCAR) in Boulder, Colo., says Florence’s power underscores new research that suggests storms are being “supercharged” by rising temperatures and that states and the federal government should do more to prepare for them....

100 Percent Renewable Pledges Do Not Equal Carbon Free Power

In recent years, scores of corporations have made renewable energy pledges. RE100, a corporate initiative aimed at getting companies to commit to purchasing all their electricity from renewables, counts 176 companies among its members, including Ikea, Coca-Cola Co. and Apple Inc. But in many cases, firms aren’t actually consuming renewable energy. They’re signing power purchase contracts with renewable developers. Electricity from the developments goes into the grid. Companies get renewable energy credits, which they use to offset emissions from their power consumption....

A Surprising New Way To Encourage Healthy Eating

Autonomy, peer relationships, and parental conflict — these are the universal themes that made the popular 1990s comic Zits identifiable for anyone who has, or has been, a teenager. In one strip, hands in pockets and making a sullen sideways glance, Jeremy slouches next to his father. His t-shirt reads, “question authority.” Next to him, his equally chagrined father sports the t-shirt: “do not question my authority.” While his parents work to steer the 16-year-old in the right direction on his path to adulthood, Jeremy is equally determined to forge his own way....

America S Long Term Care System Is Broken

The COVID pandemic devastated nursing homes. People living in long-term care facilities represent less than 1 percent of the U.S. population but account for a third of its COVID deaths: more than 174,000 people as of early March. And it wasn’t just residents—nursing home workers had one of the deadliest jobs last year. Problems with long-term care precede COVID. Most Americans say they want to remain at home as long as possible as they age, yet many cannot afford such care and wind up in a nursing facility....

Cache Crop Rodents May Have Replaced Extinct Megafauna As Seed Dispersers Video

Thousands of years ago massive elephantlike creatures wandered the landscape, gobbling up then defecating fruit. In the process, they may have planted the seeds for primordial forests. But with these creatures long extinct, ecologists have been left with a puzzle: If these trees are still with us, what—if anything—disperses these seeds to create today’s woodlands? The answer—at least for one type of forest—may lie in the criminal antics of a cunning rodent....
