Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>
The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>
Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

Copolymers will increase HDD capacity by 5 times
28.11.2012
The capacity of a computer hard drive can be increased five times thanks to processes developed by chemists and engineers at the University of Texas at Austin. To do this, the researchers use a technique that relies on the self-organization of substances known as block copolymers. The results are described in a Science article. It also focuses on real world tests in collaboration with HGST, one of the leading innovators in the disc world.
"The world has seen a steady, exponential growth in the amount of information that can be stored in the memory of an electronic device over the past few decades, but the limit has already been reached and we are running into physical limits," said S. Grant Wilson, professor of chemistry and biochemistry at the College of Engineering. and natural sciences. "The entire global industry is currently struggling to get past the one terabit per square inch limit," Wilson said. - If we simply move the points even closer together using the existing method, they will spontaneously switch from time to time, and the storage properties of hard drives will be lost. Then trouble will happen. Can you imagine that one day your bank account will just spontaneously change?"
With modern manufacturing methods, zeros and ones are written as magnetic dots on a continuous metal surface. The closer the points are to each other, the more information can be stored there. But there is a limit to saturation. The points have become so close that any further increase in their number in close proximity to each other will cause them to begin to affect the magnetic fields of their neighbors and make them unstable. However, there is one important factor: if the points are reliably isolated from each other, they can be moved much closer to each other without any destabilization.
A group of professors Wilson and Ellison succeeded in developing special self-assembled copolymers that cover hard disk platters. As a result, a bizarre pattern of the thinnest copolymer tracks is obtained on its surface, which shields the magnetic points from each other. In this case, the density of points increases fivefold. The team has made great progress on a number of fronts. With the right temperature and the right conditions, researchers have been able to synthesize block copolymers with the right parameters, which independently form insulating elements from the smallest points in the world. And amazingly, this happens in just 30 seconds, which is also a record.
