Trees often better, cheaper than technology at mitigating air pollution, study says

Science
Nov. 6 (UPI) -- Planting trees and shrubs around factories and power plants may be a better air pollution mitigation strategy than installing scrubbing technologies, according to a new study. When researchers analyzed the potential of natural and technological mitigation strategies for dozens of pollution sources, including factories, roadways, power plants, oil and gas drilling sites and more, they found natural interventions were superior roughly 75 percent of the time. The findings, published this week in the journal Environmental Science and Technology, showed natural remedies reduced air pollution by an average of 27 percent. "The fact is that traditionally, especially as engineers, we don't think about nature; we just focus on putting technology into everything," lead study author ...

Marco Silva has the lowest points per game ratio of any Everton manager since Walter Smith. The Toffees harboured hopes of a top six finish this season, but find themselves in the relegation zone after eight games, despite spending close to £100million on summer transfers.

More than a quarter of UK mammals face extinction

Science
More than a quarter of mammals are facing extinction, according to a detailed and devastating report on the state of the natural world in the UK.It also said one in seven species were threatened with extinction, and 41% of species studied have experienced decline since 1970.Providing the clearest picture to date, the State of Nature report examined data from almost 7,000 species.It drew on expertise from more than 70 different organisations. These included wildlife organisations and government agencies.The report said 26% of mammal species were at risk of disappearing altogether. A separate report outlined the picture in Scotland, where the abundance and distribution of species has also declined.Scotland saw a 24% decline in aver...
Study: Fighting climate change is more cost-effective than cleaning up the mess

Study: Fighting climate change is more cost-effective than cleaning up the mess

Science
Sept. 20 (UPI) -- It pays to fight climate change, new research suggests. Transitioning from fossil fuels to renewable energy sources won't be cheap or easy. But new research suggests the investments will pay off in the long run. That's because the cost of inaction -- letting climate change run its course and dealing with the consequences -- will be much more expensive than curbing emissions. In other words, climate mitigation efforts yield a good return on investment, researchers said. "That investment is even more compelling given the wealth of evidence that the impacts of climate change are happening faster and more extensively than projected even just a few years ago," Ove Hoegh-Guldberg, deputy director of the Australian Research Council Centre for Excellence in Coral Reef Studies,...
Common antidepressant more effective for anxiety than depression

Common antidepressant more effective for anxiety than depression

Health
Sept. 20 (UPI) -- New research suggests that an antidepressant may alleviate anxiety better than it reduces symptoms of depression. Sertraline, one of the most common antidepressants, was found to lower anxiety in people with depression, according to a study published Thursday in The Lancet. "We hope that we have cast new light on how antidepressants work, as they may be primarily affecting anxiety symptoms such as nervousness, worry and tension, and taking longer to affect depressive symptoms," Gemma Lewis, a researcher at University College London and study lead author, said in a news release. The study included 653 people in England between ages 18 and 74 who underwent surgery from a general practitioner. About 54 percent of the patients were diagnosed as depressed, while 46 percent s...
