The Physics of Sound is a fascinating topic. The study of sound and how it affects the world around us has been going on for hundreds of years. It’s important to know how sound works to understand why some sounds are pleasant while others are not – and, more importantly, what we can do about...Read More

Until now, no one has yet been able to travel through time, but the question of whether such travel is possible, purely theoretically, continues to stir the minds of scientists. Many science fiction movies, such as “Terminator” or “Back to the Future” show us that time travel can become a huge problem, violating the fundamental...Read More

It may sound surprising, but there are examples of living “three-dimensional displays” in the nature around us. Consider, for example, cephalopods, which include squids and octopuses. These creatures are capable of changing their shape, structure, texture and surface color, practically merging and becoming “invisible” in the environment. And recently, researchers from the universities of Iowa...Read More

Researchers at the University of California, Los Angeles have created what can certainly be called the world’s smallest refrigerator today. And if you thought about some miniature copy of the familiar to all unit standing in your kitchen, you are deeply mistaken. What the Californian scientists have created is actually a tiny thermoelectric cooler, which...Read More

The best models of cameras built into today’s smart phones can freeze at over 1000 frames per second, while professional, specialized cameras can freeze at a few thousand or tens of thousands of frames per second. But all these figures pale in comparison with the speed of the new absolute record holder, the fastest camera...Read More

Eating heavily processed foods increases the risk of heart failure by 58 percent, researchers warn. While critics of processed foods used to focus on their sugar content, Italian scientists have now analyzed the health effects of processed foods themselves. “Efforts to lead the population to a healthier diet can no longer be solved only by...Read More

A team of researchers from the University of Texas at Austin and the State University of Iowa said they had managed to improve the technology of reverse osmosis – a method of desalination of seawater, known to mankind for more than 200 years. The scientists’ finding improved the technology’s efficiency by 30-40 percent. Reverse osmosis...Read More
