Teen girls strike for global action on climate change – NBC News

LAUSANNE, Switzerland — It was the floodwaters brushing her jawline that convinced Theresa Sebastian it was time to get serious about climate change. The teen from Ireland was in Kerala, India, for a family wedding last summer when the region…

Did underground explosions create Titan’s lakes?

The lakes on Saturn’s moon Titan are filled with liquid methane, not water, and some are surrounded by steep rims. A new study suggests these features might have been caused by explosions of warming nitrogen, which created Titan’s lake basins long ago.

Global warming has made iconic Andean peak unrecognizable – Science Magazine

By Tim AppenzellerSep. 11, 2019 , 4:15 PM On 23 June 1802, German geographer Alexander von Humboldt and his companions could climb no higher. Plagued by altitude sickness, their gloveless hands bloodied from jagged handholds, and their boots sodden, they…

Scientists find biology’s optimal ‘molecular alphabet’ may be preordained

(Tokyo Institute of Technology) Life uses 20 coded amino acids (CAAs) to construct proteins. This set was likely evolutionarily ‘standardized’ from smaller sets as organisms discovered how to make and encode them. Scientists modeled how the adaptive properties of the CAAs evolved over time. They found that sets containing even only a few CAAs were better than an enormous choice of alternatives, suggesting each time a modern CAA was discovered, it bootstrapped the set to include still more CAAs.

Plant gene discovery could help reduce fertilizer pollution in waterways

(Boyce Thompson Institute) Excess phosphorus from fertilized cropland frequently finds its way into nearby rivers and lakes, resulting in a boom of aquatic plant growth, plunging oxygen levels in the water, fish die-offs and other harmful effects. Researchers from Boyce Thompson Institute have uncovered the function of a pair of plant genes that could help farmers improve phosphate capture, potentially reducing the environmental harm associated with fertilization. The work was published in Nature Plants.

Research sheds new light on Antarctic control of global climate

(University of Southampton) Scientists have made a new discovery that challenges previous understanding of the relationship between the polar Southern Ocean, next to Antarctica, and carbon dioxide levels in the atmosphere. Their findings show that, contrary to existing assumptions, biological processes far out at sea are the most important factors determining how the ocean absorbs carbon dioxide.
