About The Study: In 2023, reported breast and colorectal cancer screening rebounded from COVID-19 pandemic–related declines and surpassed pre-pandemic estimates. These findings are encouraging given larger-than-expected declines in early-stage breast and colorectal cancer diagnoses in 2020 and increases in distant-stage breast cancer diagnoses through 2021. Cervical cancer screening rates remained below pre-pandemic levels, a troubling trend as early-stage diagnoses continued to decrease in 2021. The persistent decline may in part reflect longer-term declines in patient knowledge and clinician recommendation of cervical cancer ...

The findings underscore how simple dietary choices could contribute to reducing the risk of chronic conditions like type 2 diabetes, ...

Sweden’s radioactive nuclear waste will be stored in a sealed bedrock repository for 100,000 years. It will be hazardous for a very long time. So how can we ensure that humanity does not forget that it is there? Researchers at Linköping University, Sweden, have come up with a proposal for how to keep the memory alive over generations. “We’re trying to do something that no one has ever done before. The person who eventually reads this might not even be human, but perhaps a kind of AI or something ...

Given the growing role of mobile technology in supporting older adults, it’s essential to implement initiatives that encourage its adoption among this population. However, older adults are often unfamiliar with mobile technology, especially those in rural areas with limited digital access or literacy. To bridge this gap, researchers from Florida Atlantic University’s Christine E. Lynn College of Nursing, and collaborators, implemented a pilot study to test an intergenerational program involving high school students, older adults and local faith-based health educators in the “Glades,” a rural community nestled at the ...

The study was published in the Journal of Cleaner Production. With the growing urgency of climate change, scientists are focusing not only on reducing ...

ITHACA, N.Y. – Experts see peer recognition as important to student success in physics, and a new study gives college-level physics instructors insight into how students perceive the message from their classmates that “you’re good at physics.” Even when women receive similar amounts of recognition from peers as men for excelling in physics classes, they perceive significantly less peer recognition, the researchers found. “Men are internalizing their recognition differently than women,” said Natasha Holmes, professor of physics at Cornell University. Holmes ...

New Haven, Conn. — Research has shown that young people who face adversity such as traumatic or stressful events during brain development are 40% more likely to develop anxiety disorders by adulthood. But most people who endure these experiences during childhood and adolescence prove to be resilient to these mental health effects. A new Yale study finds that when this adversity occurs during brain development may affect how susceptible people are to anxiety and other psychiatric problems as adults. According to the study, published March 5 in the journal Communications Psychology, ...

Embargoed until 8am GMT on Wednesday 5 March 2025 -With pictures- Our perceptions of body image are shaped by what we see from as early as seven years old, according to new research by Durham University (UK). These body ideals continue to be influenced by visual exposure to different body weights into adulthood, the research also found. The results show that people’s perceptions of body weight are flexible and adult-like from seven years of age onwards and have implications for our understanding of body size and the perceptions, and possible misperceptions, of weight in health ...

Past research has suggested that inflammation may contribute to the development and progression of dementia and that non-steroidal anti-inflammatory (NSAID) medications may help protect against dementia due to their anti-inflammatory effects. A new large prospective study published in the Journal of the American Geriatrics Society provides additional evidence, showing that long-term NSAID use is linked to a decreased risk of developing dementia. In the population-based study of 11,745 adults with an average follow-up of 14.5 years, 9,520 participants had used NSAIDs at any given time, and 2,091 participants developed dementia. Long-term NSAID use was associated with a 12% ...

A review in Clinical & Experimental Allergy concludes that exposing young children to small amounts of foods that they’re allergic to is safer than avoiding the foods altogether, which could be very dangerous if accidental exposure occurs. The review notes that exposing preschool-aged children to small amounts of food allergens—called oral immunotherapy—can lessen the severity of a reaction following an accidental exposure. Also, delaying exposure until a later age misses the window ...

Because of their high metabolic rates, sea otters are especially vulnerable to disturbances that can increase their energy needs. New research in The Journal of Wildlife Management reveals how human activities affect the behavior and energy expenditure of southern sea otters. By studying southern sea otters over 5 years at 3 sites along the coast of California, investigators found evidence that on average, the likelihood of a group of sea otters being disturbed (which affects their ability to rest) is less than 10% when stimuli such as small craft are more than 29 meters away, although this threshold varies by location, group size, ...
