High-speed network will unite scientists from China, Russia and the USA

07.01.2004

Soon Chinese, Russian and US scientists will be able to collaborate using a new high-speed network that will include the first direct link across the Russian-Chinese border.

An information highway separate from the public Internet networks will allow scientists to quickly exchange huge amounts of information and conduct various joint experiments in real time.

Russian and US scientists have been using a direct connection for about 5 years, but the exchange of information between the Russian and Chinese sides often took place at meetings in the US. The last work should be completed on the Russian-Chinese border, and on January 5, according to the plan, the network should pass the first traffic.

The ring of the network will run across the northern hemisphere, connecting Chicago, Amsterdam, Moscow, Siberia, Beijing and Hong Kong. The US National Research Foundation allocated 2,8 million USD for the creation of the network, Russia and China also contributed comparable amounts.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

robot cheating robot 18.12.2012

Georgia Tech scientists have developed robots that can fool each other. They got the idea of development in the behavioral model of ordinary squirrels and birds. The research will find a practical application in future military developments. The work is published in IEEE Intelligent Systems.

A team of scientists led by Professor Ronald Arkin began with a biological study - they studied how squirrels behave when they collect acorns and hide them in their hiding places. When another squirrel can peep the hiding place, the animal changes its behavior. Instead of going to places where her supplies can actually be stored, she visits false caches, thus making it difficult to find the real ones. It was this model that scientists transferred to robots. If an enemy is present somewhere nearby, the robot can change its patrol strategy to deceive another robot or even humans. Thus, you can buy time before the arrival of reinforcements.

In addition, Arkin studied the behavior of birds that "bluff" in the face of danger - they pretend to be stronger than they are and even attack the enemy. Not only empirical data, but also a mathematical model proves that such deception is an effective strategy, the benefits of it outweigh the risk of being caught. And in a military operation, a robot that is itself threatened can just as effectively feign the ability to fight an adversary. Even if he is unable to actually defend himself, his actions can affect the enemy's intelligent technology - make it decide that the risk is unreasonably high. "Deception, if used at the right time, can minimize the threat," says Arkin.

Professor Arkin also points out that the expansion of technology beyond the military realm, where sometimes "everything is fair" can raise many ethical questions. He strongly recommends carefully considering how morally acceptable the results of research that have taught robots to cheat.
