High blood sugar during pregnancy increases risk of mother’s type 2 diabetes, child’s obesity
JAMA Published September 11, 2018 (News releases from JAMA and National Institutes of Health) Mothers with elevated blood glucose during pregnancy – even if not high enough to meet the traditional definition of gestational diabetes – are significantly more likely to have developed type 2 diabetes a decade after pregnancy than their counterparts without high blood glucose. For […]

Melting glaciers may increase risk of landslide-triggered tsunamis
Nature Scientific Reports Published September 6, 2018 (News release from Nature Research Press) The October 17, 2015, landslide at the toe of Tyndall Glacier, which sent 180 million tonnes of rock into Taan Fiord, Alaska, affected two square kilometres of land onshore, but the resulting tsunami affected more than 20 square kilometres, with the wave runup reaching 193 metres. The […]
Climate change mitigation in Canada’s forest sector
Carbon Balance and Management Published September 5, 2017 Researchers evaluated nine mitigation scenarios in two forests management units in Canada — in Cranbrook, British Columbia, and in Dog River–Matawin Forest, Ontario. They found that very large differences existed between mitigation scenarios and that combining forest management activities with wood-use that generated longer-lived products had the highest potential to mitigate greenhouse […]
Dementia symptoms peak in winter and spring
PLOS Published September 4, 2018 (News release from PLOS) Researchers analyzed data on 3,353 people enrolled in cohort studies in the U.S., Canada, and France. Participants had undergone testing and, for some, levels of proteins and genes associated with Alzheimer’s disease were available. Adults both with and without Alzheimer’s disease have better cognition skills in late summer and […]
New guidelines for treatment of mild concussion in kids
JAMA Pediatrics Published September 4, 2018 (News release from JAMA Pediatrics) New concussion guidelines include 19 sets of recommendations on the diagnosis, prognosis, and management/treatment of pediatric mild concussion assigned a level of treatment based on confidence in evidence. Recommendations address imaging, symptom scales, cognitive testing, and standardized assessment for diagnosis; history and risk factor assessment, monitoring, and counseling […]
Uncommon mutations affect prognosis in estrogen receptor–positive breast cancer
Nature Communications Published September 4, 2018 (News release at Nature Research Press) Uncommon mutations in three genes in estrogen receptor–positive breast cancer negatively affect disease prognosis. Researchers studied archival breast cancer DNA from three cohorts of post-menopausal and pre-menopausal patients with hormone receptor–positive breast cancer and found associations with poor clinical outcomes in estrogen receptor–positive breast cancer […]

Crops make vulnerable insect-eating birds work harder for food
The Condor: Ornithological Applications Embargoed until August 29, 2018 13:00 EDT (News release from the American Ornithological Society) Tree swallows that live in cropland can still find their preferred prey, but they’re working harder to get it. Researchers examined how agriculture affects swallows’ diets, and found that birds living in croplands weighed less on average […]
A better way to count boreal birds
The Condor: Ornithological Applications Embargoed until August 29, 2018 13:00 EDT (News release from the American Ornithological Society) Researchers tested a mathematical model called a “removal model” using bird count data for 152 species from the Boreal Avian Modelling Project, which covers a vast area of Canada, Alaska, and the northeastern U.S. They found that […]
Deaths from gunshot wounds rising, mostly due to murder
