Closing coal plants saves lives, boosts crop yields

Closing coal plants saves lives, boosts crop yields

Science
Jan. 6 (UPI) -- Over the last two decades, dozens of coal plants in the United States have shuttered. The earliest victims were mostly the smallest, oldest plants, but more recently, even some of the country's largest coal plants have closed their doors. New research suggests the reductions in coal pollution are not only helping save American lives, but also boosting crop yields. According to a new study, as coal plants closed -- many of them, replaced by natural gas plants -- local pollution levels have dropped. In addition to emitting CO2, coal plants also produce more particulate matter and ozone, two main components of smog, one of the most common forms of air pollution. Studies have linked smog with a variety of human ailments, including lung disease, heart disease, stroke and cance...
Climate change: Electrical industry’s ‘dirty secret’ boosts warming

Climate change: Electrical industry’s ‘dirty secret’ boosts warming

World
It's the most powerful greenhouse gas known to humanity, and emissions have risen rapidly in recent years, the BBC has learned. Sulphur hexafluoride, or SF6, is widely used in the electrical industry to prevent short circuits and accidents. But leaks of the little-known gas in the UK and the rest of the EU in 2017 were the equivalent of putting an extra 1.3 million cars on the road. Levels are rising as an unintended consequence of the green energy boom.Cheap and non-flammable, SF6 is a colourless, odourless, synthetic gas. It makes a hugely effective insulating material for medium and high-voltage electrical installations. It is widely used across the industry, from large power stations to wind turbines to electrical sub-station...
Fluoride boosts the stability of perovskite solar cells

Fluoride boosts the stability of perovskite solar cells

Science
May 13 (UPI) -- The addition of a small amount of fluoride, the same chemical added to municipal water to prevent tooth decay, increases the stability of perovskite solar cells. Perovskite is the cheapest solar cell material available, and its efficiency has been rapidly improving. Unfortunately, it's not all that durable. Perovskite degrades quickly, undermining its long-term reliability. Over time, solar panels made of perovskite get significantly less efficient at converting the sun's rays into energy. The economic advantages of the material's affordability are quickly eroded. Researchers at the Eindhoven University of Technology in the Netherlands found they can solve the problem of perovskite's fragility by adding a little bit of fluoride during the production process. They described...
Lower blood pressure boosts brain function in elderly, study says

Lower blood pressure boosts brain function in elderly, study says

Health
March 18 (UPI) -- Having lower blood pressure can boost brain function in older adults, a new study says. When elderly people took medicine to keep their systolic blood pressure around 130 mm for three years, they were less likely to suffer a heart attack, stroke or other cardiovascular event, according to research presented at the American College of Cardiology's 68th Annual Scientific Session. "I think it's an important clinical finding and a very hopeful one for elderly people who have vascular disease of the brain and hypertension," said William B. White, a researcher at the University of Connecticut School of Medicine's Calhoun Cardiology Center and study principal investigators. "With the intensive 24-hour blood pressure treatment we reduced the accrual of this brain damage by 40 p...
Bank of America boosts CEO Brian Moynihan's pay 15% to $26.5 million after record profit last year

Bank of America boosts CEO Brian Moynihan's pay 15% to $26.5 million after record profit last year

Finance
Bank of America CEO Brian Moynihan got a 15 percent raise, the biggest increase among bank chiefs to disclose pay so far, after the lender reported record earnings last year. Moynihan's compensation rose to $ 26.5 million from $ 23 million in 2017, according to a regulatory filing Friday. That includes a $ 1.5 million salary and $ 25 million in stock units, some of which are performance-based. Bank of America, the second biggest U.S. lender after J.P. Morgan Chase, benefited last year from the corporate tax cut, rising interest rates and Moynihan's efforts to cut costs. The bank generated $ 28.1 billion in profits in 2018, 54 percent more than...
