| Posted: 15 Jun 2022 04:21 PM PDT A new study finds that adult flu vaccination dropped in states with low rates of COVID-19 vaccination, suggesting that decades of successful public health vaccination efforts may be unraveling in the wake of the COVID-19 vaccine roll out. |
| No peers, no beers: Research shows youth substance use declined during the COVID-19 pandemic Posted: 15 Jun 2022 10:08 AM PDT With stay-at-home orders during the COVID-19 pandemic, youth spent more time at home with family and were more isolated from in-person interaction with peers. Largely due to this social isolation from peers, substance use among youth declined, according to researchers. |
| Posted: 15 Jun 2022 07:29 AM PDT Data from two large cancer centres in the United States have shown that the COVID-19 pandemic caused substantial disruption to clinical trials for cancer treatment and care. After a 46% decrease in new patient accruals, and a 24% decrease in newly activated trials between March and May 2020, a bounceback was seen in 2021. The findings suggest ways of improving the running of clinical trials and improving patients access to them worldwide. |
| Military cannot rely on AI for strategy or judgment, study suggests Posted: 14 Jun 2022 03:41 PM PDT Using artificial intelligence (AI) for warfare has been the promise of science fiction and politicians for years, but new research argues only so much can be automated and shows the value of human judgment. |
| Rural areas near coast will bear the brunt of U.S. sea-level rise Posted: 14 Jun 2022 12:37 PM PDT A new analysis using highly detailed elevation maps of the Chesapeake Bay suggests that North America's extensive areas of low-lying rural land will allow coastal marshes to persist or even expand as salty water creeps upward into what are now forests and farmland. |
| Companies’ use of renewable energy certificates masks inaction on carbon emissions Posted: 14 Jun 2022 11:15 AM PDT A new study argues that renewable energy certificates -- a market-based tool that certifies the bearer owns one megawatt hour of electricity produced from renewable energy sources -- generally do not reduce emissions and firms using them are overstating their climate mitigation claims. In one calculation, the researchers show how a sample of 115 companies between 2015 and 2019 reported a 31 per cent reduction in emissions. A closer analysis of that claim reveals that without including the purchase of ineffective RECs, the actual drop in emissions was roughly 10 per cent. |
| Study explores uncertainties in flood risk estimates Posted: 14 Jun 2022 11:15 AM PDT Flood frequency analysis is a technique used to estimate flood risk, providing statistics such as the '100-year flood' or '500-year flood' that are critical to infrastructure design, dam safety analysis, and flood mapping in flood-prone areas. But the method used to calculate these flood frequencies is due for an update, according to a new study. |
| Omicron hit rural America harder than cities Posted: 14 Jun 2022 09:27 AM PDT The omicron wave of the COVID-19 pandemic in late 2021 and early 2022 spread rapidly America's densely populated cities, but led to higher rates of death in rural counties where vaccinations are lagging. Counties with vaccination rates of less than 40% had far higher mortality rates than counties with vaccination rates of 60% or more. The study recommended that health policymakers continue to make vaccination coverage a priority. |
| Suicide rates didn't increase during pandemic, study finds Posted: 14 Jun 2022 06:55 AM PDT Many people, including mental health experts, anticipated a dramatic increase in suicide rates following the outbreak of COVID-19. But in fact, this has not been the case and most of the research published in scientific journals points to either no change or a decrease in rates of suicide following the pandemic, according to a new study. |
| Stress accelerates immune aging, study finds Posted: 13 Jun 2022 12:06 PM PDT Stress -- in the form of traumatic events, job strain, everyday stressors and discrimination -- accelerates aging of the immune system, potentially increasing a person's risk of cancer, cardiovascular disease and illness from infections such as COVID-19, according to a new study. The research could help explain disparities in age-related health, including the unequal toll of the pandemic, and identify possible points for intervention. |
| Children in remote school faced more sleep, behavior and social challenges Posted: 13 Jun 2022 08:15 AM PDT Elementary school-aged children enrolled in remote learning experienced greater behavioral, learning-related, and sleep difficulties compared with children receiving in-person instruction, according to the findings of a new study. |
