Researchers evaluated changes in calorie content at 59 large restaurant chains before and after implementing mandatory menu labels. After label implementation, restaurants reduced average calorie per item by 11%. The study aimed to understand the impact of labeling on menu nutrition.
Researchers discovered that human lung stem cells can undergo abnormal differentiation in response to injury from diseases like COVID-19 and pulmonary fibrosis. This aberrant process prevents the restoration of normal lung function, but the study also identified a potential therapeutic target for reversing damage.
New research suggests that ultra-low velocity zones in the deep mantle may be regions made of different rocks than the rest of the mantle, with compositions potentially linked to the early Earth. The study's findings imply the presence of layered structures within these zones, shedding light on their origin and evolution.
Researchers propose a new plate tectonic model explaining the closure of irregular oceans and formation of curved orogenic belts through rollback subduction and rotation of convergent blocks. The study provides critical constraints on the Central Asian Orogenic Belt using digital mapping and giant 'tightly folded' magmatic belts.
A survey study investigated the prevalence of missing medical care among Medicare beneficiaries during the COVID-19 pandemic. The study found that the gap in healthcare access has persisted and worsened over time, highlighting ongoing concerns about social determinants of health.
Researchers have developed a technique called cryobioprinting that combines bioprinting with cryopreservation to create frozen, complex structures. The technology allows for the fabrication of anisotropic tissues with microscale pores aligned in specific directions, opening up new possibilities for muscular tissue engineering and beyond.
Researchers at Cedars-Sinai have identified opportunities to use microgravity in space for large-scale stem cell production, disease modeling, and biofabrication. This could lead to breakthroughs in regenerative medicine and the development of new treatments.
A systematic review of 26 studies found that the British food environment hinders weight loss efforts and maintains obesity. Policymakers are advised to address this issue through effective policy changes to create a healthier food environment.
Experts from Charité – Universitätsmedizin Berlin will deliver SARS-CoV-2 tests and train laboratory staff to monitor the Mu variant, which has spread widely throughout Colombia. The team will also support local authorities with antibody testing and knowledge transfer to inform pandemic control decisions.
A new study published in Developmental Cell reveals the mechanism of membrane curvature that allows cells to form pockets to capture substances. The researchers used high-resolution fluorescence imaging to watch these pockets form within live cells, providing a clearer understanding of how cells 'eat' and consume substances.
The newly discovered Begonia giganticaulis, a type of plant genus Begonia, has been found to be the tallest species in Asia, reaching heights of up to 3.6 meters. Its conservation status is currently listed as Endangered due to its fragmentary distribution in southern Tibet.
The study found that cancer was the second leading cause of death globally in 2019, accounting for 10 million deaths and 23 million new cases. Despite increases in absolute burden, global age-standardized mortality and incidence rates decreased by 5.9% and 1.1%, respectively.
Researchers at South Ural State University have identified biomarkers for post-traumatic stress disorder (PTSD) in veterans with long-lasting symptoms. Gamma-aminobutyric acid levels were found to be the most sensitive indicator, differing from reference values even years after traumatic events.
Researchers have developed SEAKER cells, which combine target-seeking power with the ability to locally generate potent anticancer drug for double effect. The cells use an enzyme to release active prodrug at tumor site, killing both cancer cells and those nearby that do not contain the marker.
A study of 70 youth tackle football players aged 9-12 over four seasons found a significant association between head impacts and cognitive and behavioral outcomes. The research suggests that repeated head impacts in youth tackle football may lead to long-term consequences for young athletes.
A large US-based study found that optimal gestational weight gain ranges associated with lower infant illness and death risks exist for different maternal weight categories. The study used birth data to identify these ranges and provide insights into the relationship between maternal weight gain and infant health outcomes.
