Groundwater can look clear and still carry metals that damage pipes, spoil taste, and threaten health. This study found that changing one small part of an air-powered treatment device made a major difference.

Comprehensive Formulation of Power Balance and Exergy Analysis for the Assessment of Highly Integrated Transport Aircraft

Comprehensive Formulation of Power Balance and Exergy Analysis for the Assessment of Highly Integrated Transport Aircraft

Boris Britto, Myles Zabel, Rolf Radespiel, Bernhard Weigand

Future aircraft may save energy by making the engine and the wing work as one. But that very integration makes a basic question surprisingly hard: where does the engine’s push end and the aircraft’s drag begin?

Dispersal diversity buffers species vulnerability to local extinction

Dispersal diversity buffers species vulnerability to local extinction

A species can look safe simply because it is numerous, but that headcount can miss the real danger. Its chances may depend on how differently its members move through space, and on the other species around them.

Mitigating effects on target and by-catch species fished by drifting longlines using circle hooks in the South Adriatic Sea (Central Mediterranean)

Mitigating effects on target and by-catch species fished by drifting longlines using circle hooks in the South Adriatic Sea (Central Mediterranean)

Pierluigi Carbonara, Giulia Prato, Simone Niedermüller, Sébastien Alfonso, Cosmidano Neglia, Marilena Donnaloia, Giuseppe Lembo, María Teresa Spedicato

What if a small change to a fishing hook could help sharks survive, without reducing the fishers’ catch? In the South Adriatic, researchers found a striking difference in the condition of blue sharks brought aboard.

A summer in the greater Paris: trophic status of peri-urban lakes shapes prokaryotic community structure and functional potential

A summer in the greater Paris: trophic status of peri-urban lakes shapes prokaryotic community structure and functional potential

Pierre Foucault, Sébastien Halary, Charlotte Duval, Midoli Goto, Benjamin Marie, Sahima Hamlaoui, Ludwig E. Jardillier, Dominique Lamy, Émilie Lance, Emmanuelle Raimbault, Fayçal Allouti, Marc Troussellier, Cécile Bernard, Julie Leloup, Sébastien Duperron

A lake can look calm while its invisible life is changing dramatically underneath. Around Paris, the amount of nutrient pollution helped determine not only which microbes lived in each lake, but what those microbes could do.

Phylogenetic diversity and distribution patterns of ammonia-oxidizing microorganisms in marine environments

Phylogenetic diversity and distribution patterns of ammonia-oxidizing microorganisms in marine environments

Silvia Pajares, María del Carmen Pelayo

The ocean’s nitrogen balance depends on tiny ammonia-eaters, but scientists have found that many of these workers live in places we have barely sampled, and they are not all built for the same jobs.

Meaning making and fostering radical hope: applying positive psychology to eco-anxiety research in youth

Meaning making and fostering radical hope: applying positive psychology to eco-anxiety research in youth

Catherine Malboeuf‐Hurtubise, Terra Léger‐Goodes, Catherine M. Herba, Nadia Bélanger, Jonathan Derek Smith, Elizabeth M. Marks

A young person’s fear about climate change may not be a problem to erase. It may be a signal that something important is being threatened, and that the person cares enough to act.

Impacts of climate change–simulated flooding and drought events–on terrestrial invertebrates (Enchytraeids and Collembolans)

Impacts of climate change–simulated flooding and drought events–on terrestrial invertebrates (Enchytraeids and Collembolans)

Rita C. Bicho, Janeck James Scott-Fordsmand, Mónica J.B. Amorim

A flood or drought may not kill the tiny animals in soil. The more troubling result is that they can survive while producing far fewer offspring, quietly changing the life of the soil beneath us.

Socio-economic impacts of the recent bio-invasion of Callinectus sapidus on small-scale artisanal fishing in southern Italy and Portugal

Socio-economic impacts of the recent bio-invasion of Callinectus sapidus on small-scale artisanal fishing in southern Italy and Portugal

Ludovica Nardelli, Vincenzo Fucilli, Hugo Pinto, Jennifer Nicole Elston, Annalisa Carignani, Alessandro Petrontino, Francesco Bozzo, Michel Frem

A crab invasion can turn a familiar day at sea into damaged nets, longer hours, injuries, and less money. But the same animal creates a very different crisis in two nearby European fishing regions.

Bacteriophage-derived endolysins as innovative antimicrobials against bovine mastitis-causing streptococci and staphylococci: a state-of-the-art review

Bacteriophage-derived endolysins as innovative antimicrobials against bovine mastitis-causing streptococci and staphylococci: a state-of-the-art review

Niels Vander Elst

Mastitis harms cows, dairy farms, and treatment choices, but a virus-made enzyme may offer a way to break the bacteria’s defenses without relying only on antibiotics.

A diesel spill can remain in soil for years. This study found that the strongest cleanup came not from one microbe, but from a carefully matched team of fungi and bacteria working together.

Corrosion of Titanium Electrode Used for Solar Saline Electroflotation

What if sunlight and seawater could help clean up mining, but the salty water slowly eats the machine doing the work? This study finds that a titanium electrode can withstand that challenge better than expected.
