Dams and food security

Analysis finds that dammed reservoirs could store more than 50% of the water needed to irrigate crops without depleting water stocks or encroaching on nature. The researchers caution against building new dams, however, and urge consideration of alternative storage solutions.

Whales eat colossal amounts of microplastics

Analysis of ocean plastic pollution and whale foraging behavior tracked with noninvasive tags shows whales are ingesting tiny specks of plastic in far bigger quantities than previously thought, and nearly all of it comes from the animals they eat – not the water they gulp.

Sifting through cellular recycling centers

A new method allows scientists to determine all the molecules present in the lysosomes – the cell’s recycling centers – of mice. This could bring new understanding and treatment of neurodegenerative disorders.

How benign water transforms into harsh hydrogen peroxide

A Stanford researcher and colleagues have shown that electric charge transfer when water droplets contact solid materials can spontaneously produce hydrogen peroxide, a finding with implications for cleaning and disinfection efforts.

Geological activity can rapidly change deep microbial communities

New research reveals that, rather than being influenced only by environmental conditions, deep subsurface microbial communities can transform because of geological movements. The findings advance our understanding of subsurface microorganisms, which comprise up to half of all living material on the planet.
