(Reuters Health) - Air pollution should be one of the avoidable heart risk factors - just like smoking and excess fat - that doctors warn patients to steer clear of, according to a new statement from 20 heart experts. Citing polluti...
In 2014, a 20-year-old grizzly bear named Ethyl made an epic 2,800 mile walkabout through Montana and Idaho. U.S. Fish and Wildlife Service biologists knew of her movements because of the GPS collar she wore, which sent weekly data to a satellite. Federal Grizzly Bear Recovery Coordinator Chris Servheen called her traverse into Idaho via the Bob Marshall Wilderness and Mission Mountains, which involved navigating through main streets, landfills, backyards and crossing Interstate 90, "bizarre." While male grizzlies make big movements, females rarely venture far. Yet this was but one of several similar carnivore peregrinations documented in the last fifteen years via GPS-collar technology.
Roads scare the bejeezus out of many scientists because they often open a Pandora's Box of environmental problems -- such as unleashing illegal deforestation, logging, hunting, mining, and land speculation. Far too many roads are forest...
"The recovery of large carnivores in Europe is a great success for nature conservation. At one third of mainland Europe, at least one species of large carnivore is present, according to an article in the scientific magazine Science that researchers from 26 countries have contributed to. It is an excellent example that humans and carnivores can share the same landscape, says main author Guillaume Chapron, from the Swedish University of Agricultural Sciences (SLU)
By the early 20th century, large carnivores had been exterminated from most of Europe, with just relict populations persisting. Now we have increasing or stable populations of brown bears, wolves, Eurasian lynx and wolverines, and they do not live in a remote wilderness but in a human-dominated landscape.
That is a great difference in comparison to the strategies being pursued in other parts of the world where carnivores are mainly protected in large national parks or wilderness areas, separated from people. If Europe had used that model we would hardly have any carnivores at all because there are not enough large areas of wilderness remaining."
Lauren Wood grew up in a family of river guides in the Uinta Basin region of Utah. She navigates tributaries of the Colorado River like her urban counterparts navigate subway systems. She learned to ride a horse, and then drive a car, on the Tavaputs Plateau. And she can name most any gorge or gully in the place she calls home.
But this landscape so familiar to her has transformed over the past decade to one in which drill rigs are more common than cattle herds, and methane emissions have degraded the air quality in this wilderness region to rival that of Los Angeles.
ife inside old oaks plays out at a snail’s pace. But these tree dwellers now risk paying the ultimate price as a result of the extensive cutting of trees in 16th and 17th centuries.
Hanne Eik Pilskog, a PhD candidate at the Norwegian University of Life Sciences in Ås, has spent two years investigating the hollow cavities of old oak trees in the Agder Counties and around the town of Larvik.
She is concerned about the phenomenon that biologists call the extinction debt – the future extinction of a species due to events in the past.
The elephant population in Laos is dwindling at an alarming rate. With more animals dying off than being born, the pachyderms face a real crisis. Their numbers as well their habitat need monitoring and preservation.
WASHINGTON -- Most coastal regions of the United States will see 30 or more days of flooding by 2050 thanks to sea level rise, according to new research the National Oceanic and Atmospheric Administration released Thursday.
NOAA's researchers looked at the anticipated frequency of what the National Weather Service considers nuisance flooding, which are floods that are 1 to 2 feet over the regular local high tide and are enough to cause problems but not pose active threats to human life. Some areas of the U.S. are already seeing increased flooding, the researchers said, and it's only going to get worse.
Many people are becoming aware of ways to live that are more harmonious with the planet. It seems that we are transitioning to a very ancient understanding of how to operate here on Earth, with a very advanced ‘know how’ of technologies and methods to begin making that transition. New ways of living are coming […]
Nitrates pollution of waters is a worldwide problem and its remediation is a big challenge from the technical and the scientific point of view. One of the most used and promising cleaning techniques is the biological treatment of wastewaters operated by denitrifying bacteria. In this paper we begin a thorough study of denitrifying performances of the bacterium Azospira sp. OGA 24, recently isolated from the highly polluted Sarno river in the south of Italy. Here, the kinetics of nitrates consu
A team of researchers has identified 125 million hectares (309 million acres) of land suitable for agricultural expansion that won't come at the expense of tropical forests. The study argues that shifting agricultural expansion away from forests to these 'degraded lands' would avoid 13 billion tons of carbon dioxide emissions that would be released were they converted for plantations, pasture, and croplands.

SMOKED salmon is the easy part of Christmas. Throw it on brown bread, with lemon and black pepper, and the innocents will think it’s posh and that you’ve spent a lot.
But you can get 100g of Everyday Value smoked salmon in Tesco — “responsibly sourced from the waters around Scotland, Norway or Ireland” — for €3.59.
But, today, as many of us prepare for the big Christmas supermarket shop, the Friends of the Irish Environment have ramped up their boycott of farmed salmon, strengthened by the news that the international Slow Food Movement — which counts among its supporters Bridgestone’s Sally McKenna and that icon of Irish sustainable food, Darina Allen — has condemned intensive open-pen fish farms.
“Open-net pen aquaculture is not a solution to the problem of overfishing,” says Slow Food.
“It damages natural ecosystems on a local and a global level, including wild stocks, habitats and water quality.”
A group of giant agri players, including Coca-Cola, Proctor & Gamble and Unilever, has set out plans that will inform its drive towards more sustainable agriculture in the US in the coming years.
The 66 grower organisations, agribusinesses, food, beverage and retail firms that make up the Field to Market: The Alliance for Sustainable Agriculture have committed to achieve a series of goals designed to find sustainable practices for corn, soybean, wheat, cotton, rice, potatoes and other crops. Th
What happens to degraded pastureland once the cows are kicked out? After years of letting the area rest, does it eventually become what it once was? Not likely. When disruptions such as invasive species and human interference are introduced to an area, ecological succession doesn’t occur the way it should naturally.
If you've ever wondered why the ancient structures of Rome have endured for millennia, when our own modern concrete is susceptible to cracks and crumbles, well, now you have your answer. Researchers recreated the Roman recipe and discovered that the formation of a certain kind of crystal in the concrete is the reason for the durability.
At 63, most parents are probably going to a few graduations, playing with their grandkids or just relaxing after seeing their children to adulthood. Wisdom isn't most people. In fact, she's an albatross. And at 63, the world’s oldest known, banded, wild bird just laid her newest egg.
Britain’s fishermen will be allowed to increase their catch of cod and other key fish species next year after late-night wrangling between EU ministers in Brussels resulted in a new set of fishing quotas that flout scientific advice.
The quota for cod catches for 2015 will increase by 5% on last year, though scientific advice suggested that it should be cut by 20%.
