Children's reading and writing develop better when they are trained in handwriting

Researchers explored how manual and keyboard practice influenced children's abilities in their reading and writing learning process. 5-year-olds were taught an artificial alphabet using different techniques, and the conclusion was that children who are trained with pencil and paper assimilate new letters and words better.

A virtual reality game integrating smell to fight cognitive decline

Aiming to address age-related cognitive decline, a growing global health challenge, a team of researchers has developed a VR-based smell-training system to help combat it. This innovative VR game activates memory pathways by incorporating olfactory stimulation in a virtual environment. This game-based method offers an engaging platform for maintaining cognitive function and reducing the risk of neurodegenerative diseases such as dementia in older adults. Read more ›

Restoring oil wells back to nature with moss

In what could represent a milestone in ecological restoration, researchers have implemented a method capable of restoring peatlands at tens of thousands of oil and gas exploration sites in Western Canada. The project involves lowering the surface of these decommissioned sites, known as well pads, and transplanting native moss onto them to effectively recreate peatlands. This is the first time researchers have applied the method to scale on an entire... Read more ›

When sea stars fall, sea otters rise: Sea otters benefit from prey boom triggered by loss of ochre sea stars

In 2013, a sea star wasting syndrome decimated populations of Pisaster along the west coast of North America and along the Monterey Peninsula in California, where this study was conducted. The orange and purple stars have a hungry appetite for mussels in the rocky intertidal. Without the voracious sea stars lurking around, mussel populations exploded, expanding in cover from around five percent to more than 18 percent within three years.... Read more ›

'Scratching' more than the ocean's surface to map global microplastic movement

An international team of scientists has moved beyond just 'scratching the surface,' to understand how microplastics move through and impact the global ocean. For the first time, scientists have mapped microplastic distribution from the surface to the deep sea at a global scale -- revealing not only where plastics accumulate, but how they infiltrate critical ocean systems. Researchers synthesized depth-profile data from 1,885 stations collected between 2014 and 2024 to... Read more ›

Giant croclike carnivore fossils found in the Caribbean

Imagine a crocodile built like a greyhound -- that's a sebecid. Standing tall, with some species reaching 20 feet in length, they dominated South American landscapes after the extinction of dinosaurs until about 11 million years ago. Or at least, that's what paleontologists thought. A new study shows the Caribbean Islands were a refuge for the last sebecid populations at least 5 million years after they went extinct everywhere else. Read more ›

Heart 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.

Rainfall 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. Read more ›

Global 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 healthi Read more ›

'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... Read more ›
