In Sierra Leone, onchocerciasis is a big worry in 14 out of its 16 districts. But two villages in Tonkolili district, Mangobo and Petifu, haven't seen much blindness from this disease. This raised eyebrows because, since 2005, these villages have had 17 rounds of annual treatments with ivermectin, a
Apple is expected to launch an exciting new iPhone in 2025 called the iPhone 17 Air. This model is rumored to be very thin, possibly around 5. 5mm at its thinnest point. This is much thinner than previous iPhone models. Some people are wondering if this new iPhone will have a tapered design, like th
Scientists sought to improve the way medicine, like methotrexate, passes through human skin. They used tiny needles called Dr. Pen microneedles and tiny, biodegradable beads called poly(d, l-lactide-co-glycolide) acid microparticles. These beads came in eight different forms. The team studied the be
Scientists found out that TCDD, a harmful chemical, can mess up the skull development of baby mice if their mothers are exposed to it early in pregnancy. They did scans and saw that bones were not forming properly. Some sutures, which are the places where bones meet, were fused too early. Also, part
Have you ever wondered how certain medications work differently depending on what other drugs you're already taking? That's what scientists explored in a new study about finerenone. This drug is a non-steroidal mineralocorticoid receptor antagonist, which basically means it blocks certain receptors
Have you ever wondered why honeybees are disappearing? One big reason is neonicotinoids, a type of pesticide that can harm bees. Scientists are figuring out how these pesticides stick to honeybee sensors. They found out that certain kinds of neonicotinoids, called cis-oxygen bridge ones, connect str
China's population is shrinking for the third year in a row. This might not sound like a big deal, but it's a huge challenge for the country. With fewer people being born and more people living longer, China is facing a shortage of working-age folks. This is a common problem in many places, like Jap
Samsung is diving deeper into AI with its latest move. Google's Gemini AI will soon be connected to Samsung's stock apps like Calendar, Notes, and Reminders. This isn't surprising, given Samsung and Google's tight partnership over the years. They've even worked together to save the Android smartwatc
Did you know that certain metals can help strengthen our bones? Scientists have discovered that tiny nanoparticles made from metal and plant compounds can help control how our bones are built and broken down. This is a big deal for people with osteoporosis, a disease where bones become weak and pron
When it comes to growing new bones, scientists are exploring how to design the best scaffolds for the job. These scaffolds need to be good at helping new bone grow and strong enough to hold up. Researchers have looked at different types of materials, like metals, non-metals, and polymers, to make th
