Antarctica: The ocean cools at the surface but warms up at depth

Scientists have concluded that the slight cooling observed at the surface of the Southern Ocean hides a rapid and marked warming of the waters, to a depth of up to 800 meters. These results were obtained thanks to unique data acquired over the past 25 years.

Could lab-grown plant tissue ease the environmental toll of logging and agriculture?

MIT researchers have proposed a method for growing plant-based materials, like wood and fiber, in a lab. The technology is still in early development but might one day help reduce the environmental footprint of some types of agriculture.

Fish sex organs boosted under high-CO2

(University of Adelaide) Research from Australia has found that some species of fish will have higher reproductive capacity because of larger sex organs, under the more acidic oceans of the future.

Gene-editing ‘scissor’ tool may also be a ‘dimmer switch’

In a series of experiments with laboratory-cultured bacteria, scientists have found evidence that there is a second role for the widely used gene-cutting system CRISPR-Cas9 — as a genetic dimmer switch for CRISPR-Cas9 genes.

Climate change is hurting children’s diets, global study finds

An international study of 107,000 children finds that higher temperatures are an equal or even greater contributor to child malnutrition than the traditional culprits of poverty, inadequate sanitation, and poor education. The 19-nation study is the largest investigation to date of the relationship between our changing climate and children’s diet diversity. Of the six regions examined–in Asia, Africa, and Central and South America–five had significant reductions in diet diversity associated with higher temperatures.

Scientists study salmonella swimming behavior as clues to infection

Salmonella enterica serovar Typhimurium bacteria (S. Typhimurium) commonly cause human gastroenteritis, inflammation of the lining of the intestines. The bacteria live inside the gut and can infect the epithelial cells that line its surface. Many studies have shown that Salmonella use a ‘run-and-tumble’ method of short swimming periods (runs) punctuated by tumbles when they randomly change direction, but how they move within the gut is not well understood.
