Panda love spreads to benefit the planet

Earth & Climate - 星期一, 06/26/2017 - 22:58
Loving pandas isn't just a feel-good activity. Recent work shows China's decades of defending panda turf have been good not just for the beloved bears, but also protects habitat for other valuable plants and animals, boosts biodiversity and fights climate change.

Rising seas could result in 2 billion refugees by 2100

Earth & Climate - 星期一, 06/26/2017 - 22:57
In the year 2100, 2 billion people -- about one-fifth of the world's population -- could become climate change refugees due to rising ocean levels. Those who once lived on coastlines will face displacement and resettlement bottlenecks as they seek habitable places inland, according to new research.

Microbes from ships may help distinguish one port from another

Plants & Animals - 星期一, 06/26/2017 - 22:51
Much the way every person has a unique microbial cloud around them, ships might also carry distinct microbial signatures. The key is testing the right waters -- the bilge water from the bottoms of ships.

'Solarsack' cleans water with heat from sunlight, cheaply and effectively

Earth & Climate - 星期一, 06/26/2017 - 22:50
Students have developed “SolarSack” for inexpensive and environmentally friendly water purification. The concept was tested in villages, refugee camps and slums in East Africa where it will be marketed.

Eating more vegetable protein may protect against early menopause

Plants & Animals - 星期一, 06/26/2017 - 21:36
Long-term, high intake of vegetable protein from such foods as whole grains, soy and tofu, may protect women from early menopause and could prolong reproductive function, results of a new study from epidemiologists suggest.

Amazon basin deforestation could disrupt distant rainforest by remote climate connection

Earth & Climate - 星期一, 06/26/2017 - 21:34
The ongoing deforestation around the fringes of the Amazon may have serious consequences for the untouched deeper parts of the rainforest. A new research study shows that it is not only the climate that is adversely affected by deforestation. In fact, the very stability of the ecosystem in the entire Amazon region is altered when deforestation takes place in the outermost regions.

Genes, ozone, and autism

Earth & Climate - 星期六, 06/24/2017 - 03:55
Exposure to ozone in the environment puts individuals with high levels of genetic variation at an even higher risk for developing autism than would be expected just by adding the two risk factors together, a new analysis shows. The study is the first to look at the combined effects of genome-wide genetic change and environmental risk factors for autism.

Sweet bribes for ants are key to crops bearing fruit, study shows

Plants & Animals - 星期五, 06/23/2017 - 23:05
Some flowering crops, such as beans and cotton, carefully manage the amount and sweetness of nectar produced on their flowers and leaves, to recruit colonizing ants which deter herbivores. This strategy balances their needs for defense and reproduction.

Scientists work to develop heat-resistant 'cow of the future'

Plants & Animals - 星期五, 06/23/2017 - 22:07
More than half the cattle in the world live in hot and humid environments, including about 40 percent of beef cows in the United States. By using genomic tools, researchers aim to produce an animal with superior ability to adapt to hot living conditions and produce top-quality beef.

Tropical viruses: Coming soon to Europe?

Plants & Animals - 星期五, 06/23/2017 - 22:06
The mosquito-borne viral disease Chikungunya is usually found in tropical areas. Researchers have now discovered how climate change is facilitating the spread of the Chikungunya virus. Even if climate change only progresses moderately – as scientists are currently observing – the risk of infection will continue to increase in many regions of the world through the end of the 21st century. If climate change continues unchecked, the virus could even spread to southern Europe and the United States.
