A protein complex called the constitutive centromere-associated network (CCAN) assembles inside the cell, forming a spherical shell-like structure within the nucleus. This structure is essential for faithful segregation of chromosomes and is compromised when CENP-C is removed or prevented from binding to DNA.
Global health experts warn that public health institutions must verify the accuracy of AI-generated content to ensure public health information is trustworthy. The authors argue that knowledge is a public good and that sifting truth from AI-generated content is now a core responsibility for public health institutions.
Female Anopheles mosquitoes employ a 5-step process to bite humans, combining chemical sensing and biomechanical coordination. They bite faster and hunt for blood vessels more quickly than yellow fever-carrying Aedes aegypti mosquitoes, resulting in potentially painful bites.
A new digital twin model suggests that two out of nine FDA-approved drugs have the potential to slow preterm labor. The model, called Simulated Immunome Modeling of Clinical Outcomes (SIMCO), evaluates the impact of eight drugs on immune cell activity in pregnant and non-pregnant individuals.

According to a study published in JACC: Advances, cardiac events are responsible for nearly half of all on-duty firefighter deaths in the US. The findings suggest that annual health screenings may miss heart conditions that put firefighters at risk of sudden cardiac death, such as coronary artery disease and heart muscle enlargement.
Researchers found that collective bacterial migration helps them stay ahead of phages, while also enabling phages to infect a fraction of cells near the migrating front edge. This coexistence relies on chemotaxis, or bacteria moving in response to changing chemical levels in the environment.
A pilot study tested an electronic nose, NOS.E, alongside human-remains detection dogs to detect buried human remains and confirm dog signals. The technology tracks chemical changes in decomposition, potentially helping trainers identify whether dogs need more training.
A new study led by UCL researchers found that crocodiles and their relatives followed warm climates wherever they moved, in hot periods spreading as far as Antarctica, and in colder ones retreating to the tropics. This helped them survive the asteroid that killed the dinosaurs.
Researchers discovered that plant proteins like OsNTP4 can assemble RNA chains directly from free nucleotides, challenging traditional RNA synthesis mechanisms. These proteins can generate RNA products without a template or primer, and their activity has been found to be intrinsic to the protein itself.
A European study found associations between air pollution, temperature variability, and blood glucose levels in people without diabetes. Greater exposure to air pollution, particularly PM10 particles, and increases in temperature and temperature variability were linked to higher blood glucose levels.
A team of researchers from Penn State has developed a fluorescent molecular tag that tracks viral RNA and host interactions in real-time, allowing for the study of Zika and chikungunya viruses. The tool, called Mango-II, provides insight into the viral-host cell interaction, a key step to developing effective antiviral strategies.
Researchers reconstructed 16,000 years of summer temperature changes in the Western Balkans using lake sediments and tiny insects. The findings show that temperatures warmed by up to 2.9°C between 11,800 and 11,400 years ago, and cooled by 2.3°C during the Younger Dryas event.
Researchers at Johns Hopkins Medicine report a 96% survival rate among children with severe aplastic anemia treated with half-matched bone marrow transplants from family donors. The approach expands access to potentially curative treatment, with patients experiencing strong engraftment and durable survival rates.
A new review of 30 studies found that co-viewing with parents and choosing prosocial content can help young viewers make sense of what they see. Heavy screen use can also lead to sleep problems and push out other activities.
A new AI-powered tool allows for precise estimates of bee activity, complementing traditional methods in pollinator monitoring. The tool, developed by UMass Amherst ecologist Laura Figueroa, uses audio recordings to identify bee species, achieving high precision rates and correlation with visual observations.
Researchers found evidence of avian influenza infections in polar bears in eastern Greenland, highlighting the growing concern of disease transmission in Arctic ecosystems. The study suggests that climate change is increasing the bears' exposure to new pathogens, making them more vulnerable to infections.
Researchers from the University of Ottawa and collaborators developed brain-inspired computing systems, promising a fundamentally different way to process information. These emerging technologies will lead to physical devices that are dramatically more energy-efficient, faster, and adaptive, enabling greener technology and smarter wear...
A new trial shows that a shorter three-week radiation course is as safe and effective as the standard five-week treatment for women undergoing breast reconstruction. The RT CHARM trial found no increase in complications or effects on reconstruction efforts.
