Ancient Italian writings suggest that Genoese sailors were aware of North America 150 years before Columbus' famous voyage. The discovery, made by Professor Paolo Chiesa, refers to an area known as 'Markland'/ 'Marckalada', mentioned in Icelandic sources and identified as part of the Atlantic coast of North America.
A study found that chronic stress, measured by allostatic load, was associated with a lower likelihood of completing chemotherapy and lower overall survival rate in patients with lymph node-positive or high-risk lymph node-negative HER2-negative breast cancer. Allostatic load may be a better predictor than genetic ancestry for chemothe...
The ARAMIS phase III clinical trial found that darolutamide improved metastasis-free survival and overall survival in Black/African American patients. Darolutamide-treated patients had a higher three-year overall survival rate and longer time to disease progression compared to placebo-treated patients.

A new study from Brigham and Women's Hospital identifies asthma, history of smoking, and chronic sinusitis as key risk factors for early COPD among US Hispanics/Latinos. The prevalence of early COPD was found to be 7.6 percent in this population, suggesting younger individuals are also susceptible to the disease.
Researchers found that aging workforces, characterized by a higher ratio of workers 56 and older to those ages 21-55, are associated with increased robot deployment in 60 countries. This study suggests that automation adoption is partly driven by labor shortages, particularly middle-aged labor needed for blue-collar work.

A Hong Kong study suggests a link between the COVID-19 pandemic and an increase in childhood short-sightedness, with children spending less time outdoors and more time on screens. The study found that around 1 in 5 children developed short-sightedness during the pandemic, compared to around 1 in 3 over three years.
A new study by Brown University found that the Trump administration's 'Muslim ban' led to an increase in emergency department visits and missed primary care appointments among residents from targeted nations. The study suggests that elevated cumulative stress due to a hostile climate toward Muslims may have contributed to these changes.
A 48-year record of Australian collecting trips has been made publicly available, providing accurate details on specimen collection dates and locations. The data is now accessible via the Zenodo open-data repository in Darwin Core format.
The US physician-scientist workforce doing kidney research is shifting towards more women and international medical graduates. However, this trend is accompanied by an increasing age of the workforce, a decline in relative numbers, and a shift away from basic science research.
A study of 3,013 participants found that people with disabilities cite concerns about medical conditions, functional limitations, and workplace culture as major barriers to employment. The research highlights the importance of addressing negative perceptions to develop effective return-to-work or employment interventions.
The study shows that switching to high-quality vaping products reduces health risks and provides an alternative for smokers who would not otherwise quit. The review also emphasizes the importance of consistent product manufacturing regulations and robust stewardship standards.
A large Swedish study found that first-born children have a lower risk of cardiovascular events, while people with lots of siblings are more likely to experience these events. The study also suggests that family size may play a role in cardiovascular health.
A large population-level study analyzed stool samples from over 7,000 Finnish adults and found that certain bacterial strains in the gut microbiota were associated with increased mortality risk. The study's machine learning algorithm identified specific microbial species linked to a shorter lifespan.

Research from the Rhineland Study in Bonn, Germany, suggests that neutralizing antibodies against SARS-CoV-2 decline significantly within 4-5 months after infection. The study found that only about one-third of individuals testing positive for SARS-CoV-2 antibodies actually had specific antibodies against the virus.
The study estimates the cumulative number of child deaths experienced by mothers between 20 and 49 years old in 170 countries. Mothers in select African countries are significantly more likely to have lost a child, with some experiencing up to 30 times more child deaths than those in high-income countries.

The study found that individuals with ideal CVH had a lower lifetime risk of T2D compared to those with poor or intermediate CVH.
A National Institutes of Health-funded study found that people with substance use disorders are more susceptible to COVID-19 and its complications. Individuals with a recent SUD diagnosis were more likely to develop COVID-19 and experience worse outcomes than those without an SUD.
A large population-based study suggests that people with COVID-19 should be retested 4 or more weeks after symptoms first appear to minimize the risk of onward infection. The study found a relatively high rate of false negative test results in early convalescence, highlighting the need for accurate assessment and follow-up testing.
A new study by Max Planck Institute researchers found that the risk of cognitive impairment and dementia in US men and women increased over two decades. The analysis controlled for learning effects when repeating the same test, revealing a trend reversal compared to previous studies.
A modified BACTRAC protocol allows researchers to study local leukocyte populations during human stroke using flow cytometry. This approach provides a better understanding of acute inflammatory mechanisms and may identify immunotherapeutic targets for stroke treatment.
A new study published in JAMA estimates associations between statewide school closures and changes in daily COVID-19 incidence and mortality. The analysis suggests that timely school closures in March may have contributed to reduced cases and deaths in the following weeks, accounting for other public health interventions.
Researchers successfully trained AI models to recognize individual birds using labeled images and camera traps, achieving over 90% accuracy in wild populations. This breakthrough enables long-term monitoring of populations and protects species from climate change pressures.

Exposure to high levels of flaring was linked to a 50% higher odds of preterm birth compared to no exposure, with women living near flaring sites facing the greatest risks.
Researchers have found that an individual's gut microbiota can predict and treat type 2 diabetes, with altered gut bacteria linked to reduced butyrate production. The study suggests potential for personalized dietary changes or probiotics to prevent or treat the disease.
A large randomized trial has found that endometrial scratch is not beneficial in women having their first cycle of IVF. The study involved over 1000 women under 37 years old and showed no significant difference in live birth rates between those who received endometrial scratch and those who did not.
