Research reveals Hawai'i's undersea volcano, Kama'ehu, erupted five times in past 150 years      (via sciencedaily.com)     Original source 

Kama?ehuakanaloa (formerly L??ihi Seamount), a submarine Hawaiian volcano located about 20 miles off the south coast of the Big Island of Hawai'i, has erupted at least five times in the last 150 years, according to new research led by Earth scientists at the University of Hawai'i at M?noa.

Past climate warming driven by hydrothermal vents      (via sciencedaily.com)     Original source 

An international drilling expedition off the Norwegian coast confirms the theory that methane emissions from hydrothermal vents were responsible for global warming about 55 million years ago. The study shows that the vents were active in very shallow water depth or even above sea level, which would have allowed much larger amounts of methane to enter the atmosphere.

Scientists dig into wildfire predictions, long-term impacts      (via sciencedaily.com)     Original source 

Wildfires are an ancient force shaping the environment, but they have grown in frequency, range and intensity in response to a changing climate. Scientists are working on several fronts to better understand and predict these events and what they mean for the carbon cycle and biodiversity.

Nature's kitchen: how a chemical reaction used by cooks helped create life on Earth      (via sciencedaily.com)     Original source 

A chemical process used in the browning of food to give it its distinct smell and taste is probably happening deep in the oceans, where it helped create the conditions necessary for life. Known as the Maillard reaction after the French scientist who discovered it, the process converts small molecules of organic carbon into bigger molecules known as polymers. In the kitchen, it is used to create flavors and aromas out of sugars. But a research team argues that on the sea floor, the process has had a more fundamental effect, where it has helped to raise oxygen and reduce carbon dioxide levels in the atmosphere, to create the conditions for complex life forms to emerge and thrive on Earth.

Dune patterns reveal environmental change on Earth and other planets      (via sciencedaily.com)     Original source 

Researchers have analyzed the shifting patterns of entire dune fields on Earth and Mars, as seen from orbit, and found they are a direct signature of recent environmental change. This new tool can be applied anywhere with dunes, such as Mars, Titan, and Venus.

Earth's most ancient impact craters are disappearing      (via sciencedaily.com)     Original source 

Earth's oldest craters could give scientists critical information about the structure of the early Earth and the composition of bodies in the solar system as well as help to interpret crater records on other planets. But geologists can't find them, and they might never be able to, according to a new study.

Nuisance vegetation removal in Senegalese waterways reduces the overall prevalence of parasitic infections and increases local food production      (via sciencedaily.com)     Original source 

It's an elegant solution: Remove the habitat of a parasite-carrying aquatic snail and reduce the level of infection in the local community; all while generating more feed and compost for local farmers.

Sun 'umbrella' tethered to asteroid might help mitigate climate change      (via sciencedaily.com)     Original source 

Earth is rapidly warming and scientists are developing a variety of approaches to reduce the effects of climate change. An astronomer has proposed a novel approach -- a solar shield to reduce the amount of sunlight hitting Earth, combined with a tethered, captured asteroid as a counterweight. Engineering studies using this approach could start now to create a workable design that could mitigate climate change within decades.

Plans to plant billions of trees threatened by massive undersupply of seedlings      (via sciencedaily.com)     Original source 

Major government and private funding is being invested in planting trees as a powerful tool to fight climate change. But new research shows a troubling bottleneck that could threaten these efforts: U.S. tree nurseries don't grow close to enough trees--nor have the species diversity needed--to meet ambitious planting and restoration goals.

Scientists vacuum animal DNA from air in a Danish forest      (via sciencedaily.com)     Original source 

Over 60 animal species in three days. That is how many mammals, birds and amphibians researchers found DNA traces from in the air in a Danish forest. The results can pave the way for a new and innovative way of mapping biodiversity.

Genetic study reveals that a captive-bred population could save endangered crocodile from extinction      (via sciencedaily.com)     Original source 

Performing a genetic evaluation on the largest captive-bred population of the critically endangered Orinoco crocodile, researchers have revealed that the population preserves much of its founder diversity and no inbreeding, making it suitable for implementing wild releases. Since this species is almost extinct in the wild, the news brings hope for the recovery of populations.
