Extinct gibbon found in Chinese tomb

About 2,200 years ago, a Chinese noblewoman was buried in a tomb with a menagerie of animals, including 12 horses, a leopard, a lynx and a species of gibbon unknown to modern science. The new ape, identified using detailed cranial and dental measurements as a new genus and species — Junzi imperialis — may represent the first ape to have gone extinct due to human influence after the last ice age.

Ecuadorian volcano plays its pipe

An active volcano in central Ecuador may be the largest musical instrument on Earth: After eruptions in 2015, Cotopaxi’s newly configured crater started emitting distinctly musical rumblings that scientists may be able to use to monitor future activity at the volcano.

Down to Earth With: Volcanologist Thorvaldur Thordarson

Despite growing up in Iceland, with Earth’s most volcanically active landscape as his playground, Thorvaldur Thordarson had no idea he would grow up to be a volcanologist. Nor did he suspect that his career path would take him all over the world to witness eruptions and aftermaths on six continents.

Sipping carbon-neutral fuel from the atmosphere

In the near future, vehicles may be powered by carbon that comes from the sky, rather than out of the ground. Direct Air Capture (DAC) technology pulls carbon dioxide out of the atmosphere and converts the carbon into pellets that can be used to make hydrocarbon fuel that works in traditional engines. A new study details the process, which has been tested over the last three years, and offers some cost-saving solutions that make DAC more economically feasible than ever.

Surfactants slow oceanic carbon dioxide uptake

The oceans are the largest long-term carbon sink on Earth, absorbing about a quarter of all anthropogenic carbon dioxide emissions. The rate of exchange of carbon dioxide between the oceans and the atmosphere is thought to be primarily controlled by wind-driven turbulence at the sea surface. More turbulence leads to increasing gas exchange and higher rates of carbon uptake by the ocean.

Methane emissions offset some blue carbon burial benefits

Wetlands are prolific sinks for atmospheric carbon. They pull carbon dioxide out of the air and sequester the carbon in plants, soils and sediments. But there’s a catch: Wetlands also emit methane, an even more potent, albeit far less abundant, greenhouse gas than carbon dioxide. Two new studies, one measuring methane emissions from a rehabilitated freshwater peatland in California and the other looking at emissions from tropical mangrove forests in Australia, are revealing that these so-called “blue carbon” sinks may emit much more methane than previously thought.

Dry rivers secretly star in carbon cycle

In arid environments, some seasonal rivers and streams spend more time as dry riverbeds than they do as flowing waterways. A new study is giving scientists a clearer understanding of how these intermittently dry streambeds contribute to the global carbon cycle.

Sunny Southern California burns, missing its coastal clouds

Coastal Southern California is famous for cloudless blue skies all summer long, but it hasn’t always been that way. A new study indicates that cloud cover has decreased dramatically over the beaches between Los Angeles and San Diego since the 1970s. And that could affect fires in the region.

Readying the Caribbean for the next big wave

The Caribbean is famous for clear blue waters and serene white sand beaches, and infamous for destructive hurricanes — but another type of natural disaster can also strike: tsunamis.

Ancient DNA reveals diversity of Southeast Asia

Southeast Asia is one of the most genetically and linguistically diverse regions on Earth. New sequencing of ancient human DNA is helping scientists piece together the puzzle of how repeated influxes of hunter-gatherers and farmers to the area over the last 50,000 years created the high level of diversity seen today.
