Alligators on the beach? Killer whales in rivers? Get used to it
Sightings of alligators and other large predators in places where conventional wisdom says they 'shouldn't be' have increased in recent years, in large part because local populations, once hunted to near-extinction, are rebounding. A new Duke-led paper finds that far from being outliers, these sightings signify the return of highly adaptable predators to prime hunting grounds they occupied long ago -- a trend that opens new opportunities for future conservation.

From sea to lab
With its vast numbers of different lifeforms, the sea is a largely unexplored source of natural products that could be starting points for new pharmaceuticals, such as the antitumor drugs trabectedin and lurbinectedin. Because only tiny amounts can be obtained from sea organisms, synthetic production is necessary. In the journal Angewandte Chemie, scientists have introduced a new, efficient synthetic route for these two drugs. A key step is the light-controlled activation of a carbon-hydrogen bond.

Climate change efforts should focus on ocean-based solutions
The first broad-scale assessment of ocean-based measures to reduce atmospheric CO2, counteract ocean warming and/or reduce ocean acidification and sea-level rise shows their high potential to mitigate climate change and its impacts. The study identifies ocean-based renewable energy as the most promising, and several local marine conservation and restoration options as 'no-regret measures', that should be scaled-up and implemented immediately, but concludes all other measures are still too uncertain to recommend without further research. (2018-10-04)

(2018-01-24)

Birth of a storm in the Arabian Sea validates climate model
Researchers from Princeton University and NOAA report in the journal Nature Climate Change that extreme cyclones that formed in the Arabian Sea for the first time in 2014 are the result of global warming and will likely increase in frequency. Their model showed that the burning of fossil fuels since 1860 would lead to an increase in the destructive storms in the Arabian Sea by 2015, marking one of the first times that modeled projections have synchronized with real observations of storm activity. (2017-12-06)
