New machine algorithm could identify cardiovascular risk at the click of a button
An automated machine learning program has been able to identify potential cardiovascular incidents or fall and fracture risks based on bone density scans taken during routine clinical testing....Published: April 29, 2025 - 2:31 pmHeart disease deaths worldwide linked to chemical widely used in plastics
Daily exposure to certain chemicals used to make plastic household items could be linked to more than 356,000 global deaths from heart disease in 2018 alone, a new analysis of population surveys shows. While the chemicals, called phthalates, are in widespread use globally, the Middle East, South Asia, East Asia, and the Pacific bore a much larger share of the death toll than others -- about three-fourths of the total....Published: April 29, 2025 - 2:31 pmRainfall triggers extreme humid heat in tropics and subtropics
Scientists believe they have found a way to improve warning systems for vulnerable communities threatened by humid heatwaves, which are on the rise due to climate change and can be damaging and even fatal to human health. The study analysed how patterns of recent rainfall can interact with dry or moist land conditions to influence the risk of extreme humid heat in the global tropics and subtropics....Published: April 29, 2025 - 2:28 pmGlobal study links consumption of ultraprocessed foods to preventable premature deaths
A study analyzing data from nationally representative dietary surveys and mortality data from eight countries (Australia, Brazil, Canada, Chile, Colombia, Mexico, United Kingdom, and United States) shows that premature deaths attributable to consumption of ultraprocessed foods (UPFs) increase significantly according to their share in individuals' total energy intake. The new study reinforces the call for global action to reduce UPF consumption, supported by regulatory and fiscal policies that foster healthier environments....Published: April 29, 2025 - 2:23 amA vast molecular cloud, long invisible, is discovered near solar system
Astrophysicists have discovered a potentially star-forming cloud that is one of the largest single structures in the sky and among the closest to the sun and Earth ever to be detected. The scientists have named the molecular hydrogen cloud 'Eos,' after the Greek goddess of mythology who is the personification of dawn....Published: April 29, 2025 - 2:21 amFamily first: Scientists reveal long-tailed tits' remarkable family bonds
Forget fleeting friendships the social secrets of the long-tailed tit has revealed an extraordinary level of family commitment even during migratory journeys. Birds that babysit: scientists reveal long-tailed tits' remarkable family bonds....Published: April 29, 2025 - 2:19 amHigh-wire act: Soft robot can carry cargo up and down steep aerial wires
Researchers have created a light-powered soft robot that can carry loads through the air along established tracks, similar to cable cars or aerial trams. The soft robot operates autonomously, can climb slopes at angles of up to 80 degrees, and can carry loads up to 12 times its weight....Published: April 29, 2025 - 2:19 amUsing humor in communication helps scientists connect, build trust
Scientists aren't comedians, but it turns out a joke or two can go a long way. That's according to a new study that found when researchers use humor in their communication -- particularly online -- audiences are more likely to find them trustworthy and credible....Published: April 29, 2025 - 2:17 amGeoengineering technique could cool planet using existing aircraft
A technique to cool the planet, in which particles are added to the atmosphere to reflect sunlight, would not require developing special aircraft but could be achieved using existing large planes, according to a new modelling study....Published: April 29, 2025 - 2:17 am'Wood you believe it?' Engineers fortify wood with eco-friendly nano-iron
With more than 181.5 billion tons of wood produced globally each year, a new method could revolutionize how we build sustainably. By infusing red oak with ferrihydrite using a simple, low-cost process, researchers strengthened the wood at the cellular level without adding weight or altering flexibility -- offering a durable, eco-friendly alternative to steel and concrete. The treated wood retains its natural behavior but gains internal durability -- paving the way for greener alternatives in construction, furniture and flooring....Published: April 29, 2025 - 2:17 am
