El Niño enhances CO2 uptake by North American vegetation

Science Advances Published June 5, 2019 | 14:00 EDT Long-term atmospheric CO2 observations over North America document persistent responses to the El Niño–Southern Oscillation, ocean climate influences. Increased water availability, warmer springs and cooler summers enhances carbon uptake over North America near and during El Niño. The increased uptake from North America partially offsets El […]

Humans unknowingly consume a lot of microplastics

Environmental Science & Technology Published June 5, 2019 | 08:00 EDT (News release from American Chemical Society) Humans unknowingly consume tens of thousands of tiny plastic particles per year – with unknown potential health impacts. Researchers estimate that a person’s average microplastic consumption is between 70,000 and 121,000 particles per year, with rates rising to 100,000 […]

Hummingbirds learn songs and visual
displays from peers

Proceedings of the Royal Society B: Biological Sciences Published May 29, 2019 | 17:01 EDT (Brief from the Royal Society) Hummingbird social groups share common signatures in both song parameters and visual display features. The signatures include sequence syntax, proportions of song and display elements, and fine-scale parameters of elements, and are not associated with genetic […]

Coral degradation masks predators’ smells, imperiling prey

Proceedings of the Royal Society B: Biological Sciences Published May 29, 2019 | 17:01 EDT (Brief from the Royal Society) Coral reef degradation is progressing at an unprecedented rate. With the death of corals, substantive changes occur in the odour landscape for remaining reef fish. Researchers showed that changing the background odour of a habitat dramatically […]

Super-efficient blood oxygen enables epic salmon migrations

Proceedings of the Royal Society B: Biological Sciences Published May 29, 2019 | 17:01 EDT (Brief from the Royal Society) By actively regulating the pH of red blood cells, bony fishes can control how oxygen binds to haemoglobin. They also use an enzyme to promote oxygen unloading in their tissues. This mechanism means the hearts of […]

Water research and education benefit wealthy, not
developing countries

UN University Institute for Water, Environment and Health Published May 29, 2019 | 11:00 EDT (News release from UN University) Post-secondary education and research aimed at tackling the global water crisis is concentrated in wealthy countries rather than the poorer, developing places where it is most needed. Two reports call for reducing this imbalance between resources and […]

Tiny fish make
outsized contributions to coral reefs

Science Published May 24, 2019 | 14:00 EDT (News release from AAAS) The smallest of marine vertebrates – seldom-seen, historically overlooked reef fishes – contribute 40 per cent of reef-fish biodiversity and account for nearly two-thirds of near-reef larval fish pools. They also provide nearly 57 per cent of the total fish flesh consumed by larger reef […]

30 new species of
disease-causing
bacteria identified

PLOS Neglected Tropical Diseases Published May 23, 2019 | 14:00 EDT (News release from PLOS) Researchers identified 30 new species of Leptospira, an emerging zoonotic disease that affects more than one million people around the world each year. The data provide new insights into how virulence develops in the pathogenic species. Lead author: Antony Vincent, INRS-Institut […]
