In a Policy Forum, Andrew Baker and colleagues discuss the recent regulatory action in Florida that has enabled the world’s first international coral exchange. The exchange was done to bolster genetic diversity in declining elkhorn coral populations, enhancing their resilience to climate change and other environmental pressures. Expanding such efforts to other coral species and regions will require international collaboration and a reevaluation of current conservation laws, note the authors. Coral reefs are among the most climate-sensitive marine ecosystems, with prolonged heat stress causing increasingly frequent and devastating bleaching events. For example, the historic ...

The global marine heatwaves (MHWs) of 2023 were unprecedented in their intensity, persistence, and scale, according to a new study. The findings provide insights into the region-specific drivers of these events, linking them to broader changes in the planet’s climate system. They may also portend an emerging climate tipping point. Marine heatwaves (MHWs) are intense and prolonged episodes of unusually warm ocean temperatures. These events pose severe threats to marine ecosystems, often resulting in widespread coral bleaching and mass mortality events. ...

BOSTON, July 24, 2025 – The diagnosis of a suspected lung, head, and neck cancer called NUT carcinoma should include additional testing capable of detecting gene fusions that are definitive markers of the disease, according to a study by Dana-Farber Cancer Institute investigators. The study showed that more than 75 percent of patients with NUT carcinoma may not be immediately diagnosed because standard-of-care DNA testing does not detect NUT carcinoma fusion genes. Tests that can identify gene fusions that are specific to NUT carcinoma include NUT immunohistochemistry (IHC), RNA fusion testing, ...

Superconductivity is a unique state of matter in which electric current flows without any energy loss. In materials with defects, it typically emerges at very low temperatures and develops in several stages. An international team of scientists, including physicists from HSE MIEM, has demonstrated that when defects within a material are arranged in a specific pattern rather than randomly, superconductivity can occur at a higher temperature and extend throughout the entire material. This discovery could help develop ...

New research from investigators at Mass General Brigham suggests that a commonly used type 2 diabetes medication is linked to a higher rate of heart-related conditions compared to medications that hit other targets. The study examined nationwide data from nearly 50,000 patients treated with different sulfonylureas and found that glipizide – the most widely used drug in the U.S. within this category – was linked to higher incidence of heart failure, related hospitalization and death compared to dipeptidyl peptidase-4 (DPP-4) inhibitors. ...

Cancer cells and tumors do not exist in a vacuum. Far from the isolation and self-sufficiency of the fictional Wakanda, tumors develop in and alter the nearby milieu of immune cells, connective tissue, blood vessels and a sea of proteins and carbohydrates that provide structure and other supportive functions. Cancer cells interact with this neighborhood — which scientists term the tumor microenvironment — in many ways, including obtaining extra resources needed to fuel their unchecked growth. Like a fishing trawler deploying its net, pancreatic ductal adenocarcinoma (PDAC) ...

Use of billing codes in big data sets to find diagnoses can result in up to two-thirds of cases being mistakenly identified, new UCLA-led research finds. Databases frequently used for medical research such as those for the Centers for Medicare & Medicaid Services or the National Inpatient Survey typically rely on ambulatory billing codes to identify diseases or medical procedures, but their accuracy is rarely verified in publications that rely on this data, the researchers write in a report published in the peer-reviewed journal ...

Hospitalizations and emergency department (ED) visits can be distressing and costly for nursing home residents – especially those who are severely impaired or terminally ill. Despite their vulnerability, these individuals are frequently transferred to hospitals, even though up to 40% of such transfers over the past 25 years are considered potentially avoidable by health care professionals. These unnecessary transfers not only cause distress and discomfort for residents and families but also lead to hospital-acquired complications and added costs for the health care system. In the United States, hospital transfers from nursing homes significantly ...

Schizophrenia is a serious mental health condition that affects thoughts, moods, perceptions, and behaviors. Affected individuals experience positive symptoms like delusions and hallucinations, and negative symptoms like social withdrawal, cognitive deficits, disorganized thoughts and speech, and a decreased experience of pleasure. While schizophrenia is caused by a complex interplay of genetic, environmental, and lifestyle factors, precise mechanisms remain elusive. Animal models provide valuable insights into the neurobiological mechanisms that underpin schizophrenia. However, conventional behavioral assessments ...
