A large study published in The BMJ suggests that aerobic activities such as walking, cycling, and swimming are the most effective exercises for people with knee osteoarthritis. These activities were found to provide the greatest improvements in pain, physical function, walking ability, and overall quality of life. Researchers note that while other types of exercise…
Psychologists have long debated whether the human mind can be explained by a single, unified theory or if different functions such as attention and memory must be studied separately. Now, artificial intelligence (AI) is entering that debate, offering a new way to explore how the mind works. In July 2025, a study published in Nature…
J. Craig Venter, a scientist and entrepreneur who raced to decode the human genome, died on Wednesday in San Diego. He was 79. His death was announced by the J. Craig Venter Institute, a nonprofit research organization founded by Dr. Venter and based in San Diego and Rockville, Md. The institute said in a statement…
Modern cells are highly intricate systems. They contain internal scaffolding, tightly controlled chemical processes, and genetic instructions that guide nearly everything they do. This complexity allows them to survive in diverse environments and compete based on their fitness. In contrast, the earliest cell-like structures were extremely simple. These primitive compartments were essentially tiny bubbles, where…
A newly identified species of ancient snake, Vasuki indicus, may rank among the largest snakes to ever exist. The massive reptile lived around 47 million years ago in what is now Gujarat, India, according to research published in Scientific Reports. Scientists estimate it reached an extraordinary length of about 11 to 15 meters (36 to…
Scientists have known for nearly a century that the universe is expanding, but the exact rate of that expansion is still uncertain. This ongoing debate has even raised questions about the standard model of cosmology. Now, researchers from the Technical University of Munich (TUM), Ludwig Maximilians University (LMU), and the Max Planck Institutes MPA and…
NASA’s Curiosity rover has identified a wide range of organic molecules on Mars, including compounds that scientists consider key ingredients for the origin of life on Earth. The discovery comes from a chemical experiment carried out on another planet for the first time. Results show that the Martian surface is capable of preserving molecules that…
One of the defining breakthroughs that set quantum physics apart from classical physics was the realization that matter behaves very differently at extremely small scales. Among the most important discoveries was wave-particle duality, the idea that particles can also act like waves. This concept became widely known through the double-slit experiment. When electrons were fired…
There’s a lot of buzz about Monday’s visit of Britain’s King Charles and Queen Camilla to the White House. Literally. At the beginning of the royal couple’s four-day visit to the United States, President Trump and Melania Trump, the first lady, are scheduled to show off a new White House beehive to the king and…
Mammals once shared the planet with dinosaurs until a catastrophic event 66 million years ago wiped out about 75% of all life on Earth. Even so, some species managed to survive. Among them were small, rodent-like mammals belonging to the genus Cimolodon. These animals were part of the multituberculates, a long-lived group that first appeared…
