The first signs of spring can be seen long before the flowers bloom. In the evening sky, a bright star rises low in the east, catching everyone’s eye. This star is Arcturus, the second brightest point of light we can see with the naked eye. Watching it drift across the sky feels like a gentle welcom
The planet is home to roughly ten million living kinds, from tiny fungi to giant whales. Every day, people around the world tap their phones and add a picture of something they spot to a free app that gathers this information. About six million people use it each month, giving scientists fresh data
The study looks at how a common sugar alcohol, sorbitol, affects the way κ‑casein, a protein found in milk, forms long fiber‑like structures called amyloids. In ordinary milk, κ‑casein keeps fat droplets together, but when the protein is stressed it can aggregate into ordered fibrils. Research
The idea of putting astronauts into a deep sleep or freezing them sounds like something out of a movie, but scientists are taking it seriously. In the story of “Project Hail Mary, ” a teacher wakes up on a ship miles away from Earth, but that fictional scene is just the tip of the iceberg when it co
Batched stepped wedge trials let groups start a study in separate waves, not all at once. Because each wave can differ—maybe the groups have different ages or backgrounds—the effect of the treatment might change from one batch to another. Researchers need tools that can handle this variation when th
The study explores how a closure tool, used after artery procedures, changes the blood’s movement. These devices seal holes in the femoral artery quickly, cutting down on manual pressure and speeding up healing. Even though many doctors use them routinely, scientists have not fully mapped how the
The usual way scientists look at climate and health is to focus on one extreme weather event, like a single heatwave or flood. This approach misses what happens when several harsh conditions overlap in time and space, a situation called “compound climate extreme events. ” A new review set out to
In the 1940s and 1950s, scientists who studied tiny living things were busy arguing about how to give them proper names. They debated whether a strict set of rules or a more flexible approach was best for classifying bacteria. The discussion was intense because the methods used to identify and group
Holy basil, known as tulsi, has been part of South Asian healing for thousands of years. Today scientists are testing the claims that it can ease stress, balance blood sugar and even help fight disease. The plant’s leaves, stems and seeds contain eugenol, linolenic acid and other antioxidants that m
The study looked at how different levels of blood flow restriction affect the body during light, controlled muscle movements. Researchers tested several percentages of arterial occlusion pressure (AOP) to see which level best increased muscle activation while keeping the effort feel low. They measur
