A new study finds that tree removal has far greater consequences for climate change in some soils than in others, a finding that could provide key insights into which ecosystems should be managed with extra care. In a comprehensive analysis of soil collected from 11 distinct U.S. regions, from Hawaii to northern Alaska, researchers found that the extent to which deforestation disturbs underground microbial communities that regulate the loss of carbon into the atmosphere depends almost ...

The latest results from a 25-year study of diet and aging in monkeys shows a significant reduction in mortality and in age-associated diseases among those with calorie-restricted diets. The study, begun in 1989, is one of two ongoing, long-term U.S. efforts to examine the effects of a reduced-calorie diet on nonhuman primates.

A new call that some bats use to tell other foraging bats to 'back off' from bugs they've claimed for themselves has been identified by scientists. This sound, called a 'frequency-modulated bout,' warns other bats away from prey. The researchers are first to report this ultrasonic social call produced exclusively by flying, foraging male big brown bats, in a new article.

Knowing what another person wants is not a trivial issue, particularly when the other's desires are different from our own. The ability to disengage from our own desire to cater to someone else's wishes is thought to be a unique feature of human cognition. New research challenges this assumption. Despite wanting something different to eat, male Eurasian jays can disengage from their own current desire in order to feed the female what she wants even when her desires are different to his.

Salamanders in some of North America's best habitat are shrinking fast as their surroundings get warmer and drier, forcing them to burn more energy. A new article examines specimens caught in the Appalachian Mountains from 1957 to 2007 and wild salamanders caught at the same sites in 2011-2012. Animals measured after 1980 averaged 8 percent smaller -- one of the fastest rates of changing body size ever recorded.

No more oil – renewable raw materials are the future. This motto not only applies to biodiesel, but also to isobutene, a basic product used in the chemical industry. In a pilot plant researchers now want to obtain isobutene from sugar instead of oil for the first time. And in order not to threaten food supplies, in the long term the sugar should come from wood or straw and not from sugar beet.

How does the Arctic tern (a sea bird) fly more than 80,000 miles in its roundtrip North Pole-to-South Pole migration? How does the Emperor penguin incubate eggs for months during the Antarctic winter without eating? These physiological gymnastics would usually be influenced by leptin, the hormone that regulates body fat storage, metabolism and appetite. However, leptin has gone missing in birds -- until now.

A 39-year study of wildflower blooms in a Rocky Mountain meadow shows more than two-thirds of alpine flowers changed their blooming pattern in response to climate change. Half are beginning to bloom weeks earlier, more than a third are reaching peak bloom earlier, and others' last blooms are later. Records of more than two million blooms show flowering plants' response to climate change is more complex than previously believed. Species that depend on wildflowers are likely to be affected.
