Biomedical engineers have developed a method using data from wearable devices such as smartwatches to digitally mimic an entire week's worth of an individual's heartbeats. The new 'digital twins' computational framework captures personalized arterial forces over 700,000 heartbeats to better predict risks of heart disease and heart attack. The advance is an important step toward evaluating the risks of heart disease or heart attack over months to years. Read more ›

Hair products often contain ingredients that easily evaporate, so users may inhale some of these chemicals, potentially posing health repercussions. Now, researchers have studied emissions of these volatile organic compounds (VOCs), including siloxanes, which shine and smooth hair. The scientists report that using these hair care products can change indoor air composition quickly, and common heat styling techniques -- straightening and curling -- increase VOC levels even more.

Carbon capture is essential to reduce the impact of human carbon dioxide emissions on our climate. Researchers have developed a method to confirm whether carbon in concrete originates from the raw materials, or from carbon in the air which has been trapped when it reacts with the concrete to form the mineral calcium carbonate. By measuring the ratio of certain carbon isotopes in concrete that had been exposed to the... Read more ›

The intensity and frequency of extreme rainfall increases exponentially with global warming, a new study finds. The analysis shows that state-of-the-art climate models significantly underestimate how much extreme rainfall increases under global warming -- meaning that extreme rainfall could increase quicker than climate models suggest.

A common concern about gender-affirming hormone therapy for transmasculine people is the risk of red blood cell volume changes and erythrocytosis, a high concentration of red blood cells, with the use of prescribed testosterone. However, researchers have found that testosterone treatment may be safer than previously reported. Read more ›

In the real world/digital world cross-over of mixed reality, a user's immersive engagement with the program is called presence. Now, researchers have identified reaction time as a potential presence measurement tool. Their findings have implications for calibrating mixed reality to the user in real time. Read more ›

Whether infants at five months of age look mostly at faces or non-social objects such as cars or mobile phones is largely determined by genes. The findings suggest that there is a biological basis for how infants create their unique visual experiences and which things they learn most about. Read more ›

A researcher is keen to help beekeepers shape their practices following his study which appears to disprove the widespread belief that honeybees naturally insulate their colonies against the cold. His findings suggest that the creatures are potentially being subjected to thermally-induced stress. Read more ›

A new AI (Artificial Intelligence) tool may make it possible to spare breast cancer patients unnecessary chemotherapy treatments by using a more precise method of predicting their outcomes, reports a new study. AI evaluations of patient tissues were better at predicting the future course of a patient's disease than evaluations performed by expert pathologists.  Read more ›

An international team has shown that the injection of a type of stem cell into the brains of patients living with progressive multiple sclerosis (MS) is safe, well tolerated and has a long-lasting effect that appears to protect the brain from further damage. Read more ›

The national park of Koli in eastern Finland is home to a famous, 34-metre-long crevice cave known as Pirunkirkko, or Devil's Church in English. A new study investigates the acoustics of the Devil's Church and explores whether the acoustic properties of the cave could explain the beliefs associated with it, and why it was chosen as a place for activities and rituals involving sound.

Scientists have made a surprising discovery that sheds new light on the role that oceanic deoxygenation (anoxia) played in one of the most devastating extinction events in Earth's history. Their finding has implications for current day ecosystems -- and serves as a warning that marine environments are likely more fragile than apparent. New research, published today in leading international journal Nature Geosciences, suggests that oceanic anoxia played an important role... Read more ›

Hospital MRI scanners, using 3 Tesla magnets, provide poor spatial resolution in brain imaging. More recent 7T MRIs are better but used mainly in the rare research lab. Scientists have now supercharged the standard 7T scanner to improve the resolution by nearly a factor of 10 -- a 50-times improvement over standard 3T MRIs. The NexGen 7T can track signals through the brain and perhaps tie functional changes to brain... Read more ›
