Xenotransplantation, or the process of transplanting organs from animals to humans, has made significant progress. Scientists are now planning clinical trials, but there's a big question: will people be okay with it? Understanding what people think about this is crucial. Without public support, the
One hundred years ago, a groundbreaking experiment shook the world of biology. It was not flashy or loud, but it changed how scientists think about how living things grow and develop. This experiment, done by Hans Spemann and Hilde Mangold, showed that some cells in an embryo have special powers. Th
Plants have a clever way to fight off viruses. They use a system called SAR, which stands for systemic acquired resistance. SAR acts like a plant's immune system, helping it remember past infections and protect itself better in the future. Salicylic acid (SA) and its friends, like MeSA and AzA, are
Researchers have been working hard to find a way to control HIV without daily medication. A recent study involving 10 participants showed some promising results. The participants received experimental treatments designed to boost their immune systems. After stopping their usual HIV medication, six o
Zinc-65 is a special kind of zinc that is useful in medicine and industry. Scientists wanted to find the best way to make it. They looked at different methods to see which one works best. They used special computer programs to study how different particles, like protons and alpha particles, interac
Ever wondered how cycling and visual tasks affect your brain? A small study tried to find out. They looked at how cycling on a stationary bike and a visual task, like searching for items, impact brain function. Twenty-seven young adults took part. They did four sessions. First, they checked their f
In the first four months of life, a baby's immune system goes through big changes. This is how it works in Papua New Guinea. Researchers looked at 87 babies. They checked 41 different immune system messengers in the blood. These messengers are called cytokines and chemokines. At birth, the levels o
Rubidium is a valuable element found in salt-lake brines, but extracting it has been a tough job. The usual methods aren't great at picking out rubidium from other stuff like sodium, potassium, calcium, and magnesium. But now, there's a new trick: using a special material with lots of sulfonic acid
Non-lethal weapons are meant to control people without killing them. But sometimes, they can still hurt or even kill if used too close. So, a new kind of projectile was made. It's called a frangible projectile. It's small, about 18. 4 mm, and it's made of a special plastic called PMMA. Inside, it ha
In the early 20th century, a big collection of old Irish folk remedies was put together. These remedies were used to treat all sorts of illnesses. The people who used them were mostly from the countryside and were born between 1850 and 1925. Some of these remedies were pretty unusual. They involved
