Leukemia is a sneaky disease. It creates a tough environment for the immune system to fight back. Acute myeloid leukemia (AML) is one type that is particularly tricky. It uses different tricks to hide from the immune system's T cells, which are supposed to attack and destroy it. One of these tricks
Tin dioxide (SnO2) gas sensors have been with us for a long time, yet their inner workings are still shrouded in mystery. This lack of understanding makes it hard to improve these sensors. Scientists have been working to figure out how these sensors function. A major breakthrough came when research
Bones are made up of tiny, mineralized collagen fibers. These fibers are like the bricks that build a wall. The process of turning these fibers into bone is controlled by special proteins. But studying these proteins in a living body is tough. So, scientists used a clever trick. They used different
Nitrogen is a big player in how atmospheric organic aerosols (OAs) absorb sunlight. These tiny particles in the air affect Earth's climate. But, the way they change and absorb light is still a mystery. Scientists have found that brown nitrogen (BrN), a nitrogen-rich part of OAs, is the main absorb
Oxygen is essential for life, but too much of it can be harmful. This is especially true when it comes to supplemental oxygen therapy. In cases like bronchopulmonary dysplasia (BPD) in premature babies and acute respiratory distress syndrome (ARDS) in adults, too much oxygen can lead to lung injury.
Climate change is shaking up the world in many ways. One of the most alarming is how it affects bacteria and the viruses that keep them in check. These viruses, called bacteriophages, play a crucial role in controlling bacterial populations. But as temperatures rise, their ability to do so is changi
Plants have a clever way of defending themselves against invaders. They use special receptors on their cell surfaces to spot trouble. These receptors can pick up signals from both the bad guys (pathogens) and helpful peptides released by the plant itself. This is like having a security system that c
The ocean is full of tiny heroes that help keep life going on Earth. These heroes are bacteria that can turn nitrogen from the air into a form that plants can use. For a long time, scientists thought that only certain types of bacteria, like cyanobacteria, could do this in the ocean. But guess what?
Picture this: You're in a hospital, gasping for air, but the oxygen you need is nowhere to be found. This isn't a rare scenario. Every day, millions of people worldwide face this exact dilemma. Oxygen is a lifeline for those with breathing difficulties, infections, or recovering from operations. Yet
Menopause is a natural phase in a woman's life, but it can bring some unwanted changes. Estrogen, a hormone, plays a big role in keeping bones strong, skin healthy, and the heart and brain in good shape. When estrogen levels drop during menopause, it can lead to issues like hot flashes, wrinkles, dr
