Proceedings of the Royal Society B: Biological Sciences Published April 3, 2019 | 17:01 EDT (Brief from the Royal Society) If we fall apart as we age because we allocate so much energy to trying to reproduce that we don’t look after our bodies, then males that have to compete more vigorously should age faster. In […]

Losing a mating match boosts loser’s sperm competitiveness 
Proceedings of the Royal Society B: Biological Sciences Published April 3, 2019 | 17:01 EDT (Brief from the Royal Society) When researchers tested the mating success of winners and losers in a variety of mating competitions, they found that winners are better at acquiring mates, but losers perform better in sperm competition. These results have important […]
Slippery slopes: Climate change is reshaping the Arctic landscape
Nature Communications Published April 2, 2019 | 11:15 EDT (News release from University of Ottawa) The number of landslides caused by melting permafrost ice on Banks Island, in the Canadian Arctic, increased from 63 in 1984 to 4,077 in 2013. More than 85 per cent of the slumps occurred just after four particularly warm summers. The […]

Early observations from near-Earth asteroid Bennu
Nature Geoscience and Nature Astronomy Published March 19, 2019 13:30 EDT (News release from Nature Research Press) Early observations from instruments aboard NASA’s OSIRIS-REx spacecraft confirm the presence of widespread and abundant hydrated minerals on near-Earth asteroid Bennu and the unexpected presence of numerous, large boulders, suggesting that Bennu is between 100 million and one billion years […]
How geography shaped North American Indigenous languages
Proceedings of the Royal Society B: Biological Sciences Published March 27, 2019 | 17:01 EDT (Brief from the Royal Society) Researchers modelled North American language diversity at time of European contact, using influences such as topography, rivers, climate change since the last Ice Age, precipitation, and other ecological factors, to gain insight into the factors that […]
Prepare for drought conditions in southern Canada as the Arctic warms
Nature Published March 27, 2019 | 14:00 EDT When Arctic regions warmed relative to equatorial regions beginning about 12,000 years ago, temperate regions saw substantially less rain- and snowfall, researchers say. Palaeoclimate records from the end of the last Ice Age to some 5,000 years ago and climate simulations indicate that weakening temperature gradients led to […]

Freeze-tolerant insects draw on a range of protectant molecules
Proceedings of the Royal Society B: Biological Sciences Published March 20, 2019 17:01 EDT (Brief from the Royal Society) Low temperatures kill most animals, but some insects can survive ice forming inside their bodies. Researchers tested how small-molecule cryoprotectants work the freeze-tolerant spring field cricket, showing that different cryoprotectants have unique impacts on freeze tolerance. The information […]
Trouble in the OR: Clinicians report assault, verbal abuse, intimidation
Canadian Journal of Anesthesia Published March 19, 2019 21:00 EDT Canadian and U.S. clinicians experienced almost 1,000 physical assaults in operating rooms in 2012–2014. Verbal threats and other forms of intimidation occurred. Clinicians working as nurses, working in privately funded clinics, or who were young, inexperienced, female, or non-heterosexual were most likely to experience abuse. A […]
Daily use and high-potency cannabis linked to higher rates of psychosis
The Lancet Psychiatry Published March 19, 2019 19:30 EDT (News release from The Lancet) In cities where high potency cannabis is widely available, such as London and Amsterdam, a significant proportion of new cases of psychosis are associated with daily cannabis use and high-potency cannabis. The authors estimate that one in five new cases (20.4%) of psychosis […]

Why some young adults engage in unsafe sex
Journal of Sex Research Published March 19, 2019 00:00 EDT (News release from Taylor & Francis Group) Gender, sexual orientation, and the desire to form lasting romantic relationships appear to influence sexual risk-taking among young adults. This is the first study to directly compare how heterosexual men, heterosexual women, and homosexual men differ in their approach […]
Otters leave their own archaeological records
Scientific Reports Published March 14, 2019 14:00 EDT (News release from Nature Research Press) Sea otters leave distinct wear patterns on the rocks that they use to break open hard-shelled food. The patterns, which can be recognised using archaeological techniques, could help trace locations of previous sea otter populations that are now extinct. Images and video […]
Catastrophic dynamics limit Atlantic cod recovery
Proceedings of the Royal Society B: Biological Sciences Published March 13, 2019 17:01 ET (Brief from the Royal Society) Researchers applied a model from catastrophe theory to Atlantic cod (Gadus morhua) stocks. The resulting patterns of restoration reflect the combined effects of fishing pressure and temperature increase that limit the species’ recovery potential. These dynamics help […]
Tool tracks gentrification across cities
PLOS One Published March 13, 2019 (News release from PLOS) Researchers trained a computer model to search Google Street View’s images of Ottawa properties from 2007 to 2016 for changes that could indicate gentrification – for example, new fences, repainting, or new windows. The results were almost as accurate at detecting gentrification indicators as a human […]
