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 ›

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.

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 ›

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 ›

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. Read more ›

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. Read more ›

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 ›

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. Read more ›

Crystals -- from sugar and table salt to snowflakes and diamonds -- don't always grow in a straightforward way. Researchers have now captured this journey from amorphous blob to orderly structures. In exploring how crystals form, the researchers also came across an unusual, rod-shaped crystal that hadn't been identified before, naming it 'Zangenite' for the graduate student who discovered it.

Climate change is increasing the risk of wildfires in many regions of the world. This is due partly to specific weather conditions -- known as fire weather -- that facilitate the spread of wildfires. Researchers have found that fire weather seasons are increasingly overlapping between eastern Australia and western North America. The research team examined the causes of this shift and its implications for cross-border cooperation between fire services in... Read more ›

In the past 20 years, the average rate of obesity among adults in the United States has risen by approximately 30 percent, but the rate of those with the most severe forms of obesity, or those with a body mass index, or BMI, of more than 60 kg/m2, increased by 210 percent. Researchers analyzed national health data from 2001 through 2023, and discovered the alarming increase in the numbers of... Read more ›

Researchers have developed a new catalyst design capable of pushing the projected fuel cell catalyst lifespans to 200,000 hours. The research marks a significant step toward the widespread adoption of fuel cell technology in heavy-duty vehicles, such as long-haul tractor trailers. While platinum-alloy catalysts have historically delivered superior chemical reactions, the alloying elements leach out over time, diminishing catalytic performance. The degradation is further accelerated by the demanding voltage. Read more ›
