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 […]

Trading gizzard mass for flight muscles:
Remodelling
migratory bird bodies

Proceedings of the Royal Society B: Biological Sciences Published May 22, 2019 | 17:01 EDT (Brief from the Royal Society) Many long-distance migratory birds undergo seasonal flight-muscle build up to power long-distance flights and digestive-machinery break down to reduce body mass. Captive experiments with the red knot shorebird reveal that these body-remodelling patterns can be […]

Bunting hunting speeds tasty songbird’s decline

Science Advances Published May 22, 2019 | 14:00 EDT (News release from AAAS) Up to 30,000 ortolan buntings are killed illegally for food each year in southwest France, where hunters say the migrating songbirds come from large, stable populations elsewhere in Europe. Genetic testing, tiny electronic bird-backpack trackers, and feather-isotope analysis confirm the birds come from small, […]

Insight into how ice forms on other planets and in space

Nature Published May 22, 2019 | 13:00 EDT (News release from Oak Ridge National Laboratory) In an experiment designed to create a super-cold state of water, scientists unexpectedly discovered how dense, crystalline phases of ice thought to exist beyond Earth’s limits might form. Observation of the crystalline ice phases challenges accepted theories about water and […]

First fungus among us: Billion-year-old fungi found in Arctic

Nature Published May 22, 2019 | 13:00 EDT (News release from Nature Research Press) Researchers identified fossil fungi dating from 900 to 1,000 million years ago in Arctic Canada. The findings provide evidence that fungi evolved 500 to 600 million years earlier than previously thought, pushing back the origins of the group of animals that […]
