A mouse's brain is tiny, but it's packed with intricate details. Tiny sections of brain tissue, about the size of a grain of sand, can contain hundreds of thousands of cells. These cells are linked together by miles of wiring. This complexity has always been a challenge for scientists. In the late 1970s, a famous scientist named Francis Crick thought that understandi...
The solar system might have a ninth planet. It is hiding far beyond Neptune. Scientists have been looking for it for years. They have not seen it yet. The evidence comes from strange orbits of small, icy bodies. These orbits suggest a large planet is pulling them with its gravity. A powerful telescope is almost ready. It is in Chile. The Vera C. Rubin Observatory wi...
Nowadays, computers are way more powerful than before. This has led to some amazing developments in data science. One of these is reinforcement learning, or RL for short. It is a type of machine learning that helps make decisions in complicated situations. It is super useful in healthcare operations management. This is because healthcare often involves a lot of uncer...
The world of sports is changing fast. Technology is making it easier to track how athletes move. This is thanks to 3D motion capture systems. These systems come in different forms. Each has its own way of working. Some use a single camera with depth estimation. Others use a single camera with depth sensors. There are also systems that use multiple cameras. Ea...
Brazil is home to a unique landscape called canga. This is a type of rocky terrain that is rich in iron. It is also home to many plants that are found nowhere else in the world. Two of these plants are Lippia hermannioides and Matayba marginata. These plants grow in a specific type of environment known as ferruginous rupestrian fields. These fields are found on the r...
The latest buzz in the AI world centers around Thinking Machines Lab, a startup making waves with its recent additions. Bob McGrew and Alec Radford, both former key figures at OpenAI, have joined the team as advisers. McGrew, who held the position of chief research officer at OpenAI, and Radford, known for his groundbreaking work on generative pre-trained transform...
In Oman, there is a noticeable gap in understanding how the public views the system used to prioritize patients in emergency rooms. This system is called triage, and it is crucial for deciding who needs immediate attention. A recent effort focused on exploring this topic at a major hospital in Muscat. The hospital in question is a key player in the healthcare system...
The topic of how aging affects people with autism is relatively new. It's a subject that needs more attention. A recent effort looked at studies on how the brain and mind change with age in autistic individuals. The research focused on both the brain's structure and function, as well as cognitive abilities like processing speed, memory, and executive function. Th...
Down syndrome is more common than many people think. Let's dive into some facts and figures. First, what is Down syndrome? It is a genetic condition. It happens when a person has an extra copy of chromosome 21. This extra chromosome can cause delays in physical growth and intellectual development. It can also lead to various health problems. It is important to...
Randomized controlled trials (RCTs) are often called the gold standard in medical research. They help figure out if a treatment or intervention works and if it is safe. However, the math behind these trials can be tricky. Understanding some basic math ideas is key to knowing if the results really matter. First, let's talk about P-values. These numbers show if the re...
