Toronto, ON, November 4, 2024 – People with a history of concussion face a 25% higher risk of having severe mental health issues after childbirth, according to a new study from ICES and the University of Toronto.  The research underscores the importance of identifying individuals with past concussions early in their prenatal care and highlights the need for long-term, trauma-informed support to safeguard their mental health.  “We found that individuals with a history of concussion were significantly more likely to experience serious mental health challenges, ...

ITHACA, N.Y. – A popular new strategy for combatting misinformation doesn’t by itself help people distinguish truth from falsehood but improves when paired with reminders to focus on accuracy, finds new Cornell University-led research supported by Google. Psychological inoculation, a form of “prebunking” intended to help people identify and refute false or misleading information, uses short videos in place of ads to highlight manipulative techniques common to misinformation, such as emotional language, false dichotomies and scapegoating. The strategy has already been deployed ...

CAMBRIDGE, MA – Silicon transistors, which are used to amplify and switch signals, are a critical component in most electronic devices, from smartphones to automobiles. But silicon semiconductor technology is held back by a fundamental physical limit that prevents transistors from operating below a certain voltage. This limit, known as “Boltzmann tyranny,” hinders the energy efficiency of computers and other electronics, especially with the rapid development of artificial intelligence technologies that demand faster computation. In an effort to overcome this fundamental limit of silicon, MIT researchers fabricated a different type ...

When torrential rains and powerful winds hit densely populated coastal regions, whole cities can be destroyed—but governments and residents can take precautions with sufficient warning. Many of these coastal deluges are caused by atmospheric rivers—regions of concentrated water vapor carried along on strong winds, sometimes called “rivers in the sky.” Meteorologists monitor them, but the ability to predict exactly how an atmospheric river might behave based on its underlying physics would offer more precise forecasts. In a paper published today in Nature Communications, senior author Da Yang, assistant professor of geophysical sciences at the University ...

More children have overweight in regions with high rates of single parenthood, low education levels, low income and high child poverty. The pandemic may also have reinforced this trend. This is shown by a study conducted by researchers at Uppsala University and Region Sörmland in collaboration with Region Skåne. “During and after the pandemic, we see a greater difference between regions in terms of children's weight. It even looks like it has exacerbated health inequalities,” explains ...

Researchers have identified 22 pesticides consistently associated with the incidence of prostate cancer in the United States, with four of the pesticides also linked with prostate cancer mortality. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society. To assess county-level associations of 295 pesticides with prostate cancer across counties in the United States, investigators conducted an environment-wide association study, using a lag period between exposure and prostate cancer incidence of 10–18 years to account for the slow-growing nature of most prostate cancers. The years 1997–2001 ...

The AI tool AlphaFold has been improved so that it can now predict the shape of very large and complex protein structures. Linköping University researchers have also succeeded in integrating experimental data into the tool. The results, published in Nature Communications, are a step toward more efficient development of new proteins for, among other things, medical drugs. In all living organisms, there is a huge variety of proteins that regulate cell functions. Basically, everything that happens in the body, from controlling muscles and forming hair to transporting ...

**EMBARGOED UNTIL RELEASE MONDAY, NOV. 4, AT 1 A.M. ET** Researchers including a Johns Hopkins University evolutionary biologist report they have analyzed a fossil of an extinct giant meat-eating bird — which they say could be the largest known member of its kind — providing new information about animal life in northern South America millions of years ago. The evidence lies in the leg bone of the terror bird described in new paper published Nov. 4 in Palaeontology. The study was led by Federico J. Degrange, a terror bird ...

We use our lips to talk, eat, drink, and breathe; they signal our emotions, health, and aesthetic beauty. It takes a complex structure to perform so many roles, so lip problems can be hard to repair effectively. Basic research is essential to improving these treatments, but until now, models using lip cells — which perform differently to other skin cells — have not been available. In a new study published in Frontiers in Cell and Developmental Biology, scientists report the successful immortalization of donated lip cells, ...

About 1 in 3 patients diagnosed with cancer in Ontario visited an emergency department (ED) in the 90 days before diagnosis, found a new study published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.240952. In a study that included more than 650 000 patients diagnosed with cancer between 2014 and 2021 in Ontario, 35% (229 683) had visited an ED in the 90 days before diagnosis. Among patients with ED visits before their cancer diagnosis, 64% had visited once, 23% had visited twice and 13% had 3 or more visits. ...

Former teacher Professor of Education David Putwain says ‘heavy-handed’ messages around test results can fuel extreme worry among some 16 to 18-year-olds, even when others respond well to such messages. Putwain identifies several risk factors, for example students with certain personality traits, including those who are highly self-critical, can underachieve because of severe anxiety in exams. Certain demographics also report higher exam anxiety, including female persons and those from economically deprived backgrounds. ‘Temperature checks’ to identify at-risk ...

A study co-led by a Johns Hopkins Children’s Center clinician-researcher shows that adding text messaging and other electronic feedback to traditional in-clinic health counseling for parents about feeding habits, playtime and exercise prevents very young children from developing obesity and potentially lifelong obesity-related problems. Findings from the study, which was co-led by Eliana Perrin, M.D., M.P.H., Bloomberg Distinguished Professor of Primary Care at the Johns Hopkins University Schools of Medicine, Nursing and Public Health, will be published in JAMA and presented at the Obesity Society’s “Obesity Week” in San Antonio, both on Nov. ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have created a mathematical model that models how the evolutionary strategies of organisms are affected by the environment. They studied salmonid fishes which choose either to migrate to the sea then return to lay eggs or stay in the river depending on their individual features. Their model correctly predicts how the proportion choosing to migrate changes with environmental conditions, predicting how environmental change can trigger eco-evolutionary responses.   Salmonids (or salmon-like) fish are known to face a tough choice early in their lives. They can either stay where they are ...

HOUSTON-(Nov. 1, 2024) – A concerning increase in global rates of severe invasive infections becoming resistant to key antibiotics has a team of infectious disease researchers at the Houston Methodist Research Institute studying a recently emerged strain of bacteria called Streptococcus dysgalactiae subspecies equisimilis (SDSE). SDSE infects humans via the skin, throat, gastrointestinal tract and female genital tract to cause infections ranging in severity from strep throat (pharyngitis) to necrotizing fasciitis (flesh-eating disease).   Closely related to group A streptococcus (also commonly known as Streptococcus pyogenes), which has been very well studied, ...

Windblown dust from the shrinking Salton Sea harms the respiratory health of children living nearby, triggering asthma, coughing, wheezing and disrupted sleep, USC research shows. The findings also indicate that children living closest to the sea, who are exposed to more dust in the air, may be the most affected. The study, published in Environmental Research, found that 24% of children in the area have asthma — which is far higher than the national rate of 8.4% for boys and 5.5% for girls. The abnormally high rate raises health experts’ concerns about the children’s health in this predominantly low-income community of color 150 miles southeast of Los Angeles. Furthermore, ...

With only days to go in the 2024 general election, the Applied Political Analytics Program (APAN) at the University of Maryland, in partnership with the public opinion firm YouGov, released today the results from an Oct. 23-27, 2024 poll of 500 likely Maryland voters that finds broad support for reproductive freedom, and Angela Alsobrooks (D) with a sizeable lead over former Maryland governor Larry Hogan (R) in the race to fill a U.S. Senate seat.  The poll found that across the state, Kamala Harris (D, 60.9%) holds a 27 percentage-point lead over Donald Trump (R, 33.9%). The data also show Angela Alsobrooks (D, 57.4%) with a ballooning 23 percentage-point ...

A new USC study involving 8,500 children from across the country reveals that a form of air pollution, largely the product of agricultural emissions, is linked to poor learning and memory performance in 9- and 10-year-olds. The specific component of fine particle air pollution, or PM2.5, ammonium nitrate, is also implicated in Alzheimer’s and dementia risk in adults, suggesting that PM2.5 may cause neurocognitive harm across the lifespan. Ammonium nitrate forms when ammonia gas and nitric acid, produced by agricultural activities and fossil fuel combustion, respectively, react in the atmosphere. The findings appear in Environmental Health Perspectives. “Our study ...

Medicare-certified home health agencies, which are key to allowing older adults to age in place, are increasingly going through ownership changes, raising concerns about health care spending, workforce, and quality of care, according to a study by UTHealth Houston. The research was published in JAMA Health Forum, part of the Journal of the American Medical Association. “The ownership change in health care sectors — including various forms of acquisitions by health systems, insurers, private equity firms, and other corporate investors — is increasingly reshaping U.S. health care system and causing concerns about quality of care,” said Yucheng Hou, PhD, assistant ...

Member states of the European Union are obliged to designate Special Protection Areas (SPAs) as part of the Natura 2000 network. These areas are designed to guarantee the preservation and restoration of bird populations. However, due to the paucity of data about rare species, it was not known how well these areas worked. Researchers at the University of Göttingen and Dachverband Deutscher Avifaunisten (DDA) developed citizen science platforms as a new data source to evaluate the effectiveness of the 742 protected areas for birds ...
