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 […]

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 […]

Food insecurity in Nunavut increased after food program introduced

Canadian Medical Association Journal  Published May 21, 2019 | 00:15 EDT (News release from Joule Inc.) In 2010, before the Nutrition North Canada program began, 33 per cent of households in Nunavut communities experienced food insecurity. By 2014, when the program was implemented, 46 per cent of households reported food insecurity. Lead author: Andrée-Anne Fafard St-Germain, […]

First results from New Horizons space mission: Untouched for 4.5 billion years

Science Published  May 16, 2019 | 14:00 EDT (Summary by AAAS) The first results from the New Horizons spacecraft’s flyby of Kuiper Belt object MU69, or Ultima Thule, show it is an ancient relic that has remained largely untouched – even by the heat of the Sun – since its formation roughly 4.5 billion years […]

Targeted laser
therapy closes single blood vessels

Science Advances Published May 15, 2019 | 14:00 EDT (Summary by AAAS) A new method to selective close single blood vessels within tissue uses laser therapy called multiphoton photothermolysis. The precise microsurgery technique could be used to treat vascular diseases and malfunctioning blood vessels in cancers, macular degeneration, and port wine birthmark stains.
