Wolverines in North America have some serious dental issues. A recent study looked at over 180 wolverines from Alaska. Most of them were adults, with only a few young ones. The study found that almost all of them had gum disease, but it was usually mild. More than two-thirds had broken teeth, with the breaks going deep into the tooth structure. This is likely because...
Scientists have found a way to make amoxicillin more powerful by teaming it up with silver. This isn't just a simple mix. They've created two new forms: one where amoxicillin and silver are tightly bound together, and another where tiny silver particles are stabilized by amoxicillin. The goal? To tackle stubborn bacteria that have become resistant to regular antibiot...
People in Chile are getting bigger faces, and that's a problem for mask fit. A recent study looked at how faces have changed over the last decade and how well masks fit now compared to before. The study used two sets of data: one from 2013 with manual measurements and another from 2024 using 3D scans. They measured 11 different parts of the face, following internatio...
Traffic conflicts are like warning signs on roads. They show where crashes might happen. But not all spots on a highway are the same. Some areas have more risks than others. This study looked at traffic conflicts on U. S. 101. It used a special method to see how risks change in different zones. Usually, people think crash risks are the same everywhere. But this stud...
Strength training is all about understanding how different exercises work your muscles. A recent study dug into how two common exercises, the isometric squat and the isometric mid-thigh pull (IMTP), compare in terms of force and muscle activation. The study involved 15 people, mostly men, who were asked to perform both exercises while their muscle activity was measu...
Deep under a parking lot in Denver, a museum known for its dinosaur exhibits made an unexpected discovery. While exploring geothermal heating options, they drilled over 750 feet down. What they found was a tiny fossil, about the size of a hockey puck. This fossil is a vertebra from a small, plant-eating dinosaur that lived around 67. 5 million years ago, just before ...
Scientists are always looking for better ways to study the brain. One tool they use is called PET scanning. This tool helps them see how different parts of the brain work. But the data from these scans can be tricky to understand. One method to make sense of this data is called spectral analysis. It's like a filter that helps scientists focus on specific brain activ...
Bacteriocins and essential oils are like a dynamic duo in the fight against harmful microbes. They have shown promise in working together to tackle tough pathogens. However, scientists are still trying to figure out exactly how they do this, especially when it comes to Gram-negative bacteria and fungi. Enterocin Gr17 (ENT) is a new type of bacteriocin that has been ...
Vitamin K2 (VK2) is gaining attention for its potential to tackle obesity and related health issues. Researchers wanted to see how VK2 affects different organs in mice fed a high-fat diet. They split 28 mice into groups and gave them either VK2 or a placebo while feeding them high-fat or normal diets. After 16 weeks, they examined changes in the brain, colon, muscle,...
In the world of microbes, Streptomyces sp. NRRL S-1813 is a standout. This special bacterium is like a tiny factory, capable of producing useful chemicals. Scientists wanted to see what this microbe could make when given different food sources. They found something interesting: two related chemicals, oxazolomycin A and oxazolomycin A2, being produced at the same time...
