Are there man-eating tigers?

Yes. In 1869, a Bengal tiger was killed, which had previously killed 127 people. Man-eating tigers are still encountered today: in 1979, 18 people fell victim to a tiger.

Whose clothes had more than 10 buttons sewn on?

Buttons appeared long before our era, but were used only as decoration. Around the 12th and 13th centuries, buttons were again recognized in Europe, but now they also had a functional meaning of fastening in loops, and not just a decorative one. In the Middle Ages, buttons became such a popular accessory that one could judge the status of the owner by their number on clothes. For example, on one of the outfits of the French king Francis I, there were 13 buttons.

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 ... >>

Silicone instead of copper 12.02.2013

A team of researchers from IBM and Dow Corning Electronics announces a discovery that will allow silicon to displace copper in creating fast, energy-efficient photonic connections on printed circuit boards. The team demonstrated optical waveguides using a photonic polymer at Photonics West 2013 in early February.

IBM says its work with Dow Corning provides an integrated approach to optical communications, similar to how metal conductors now conduct electrical signals on traditional printed circuit boards. Silicone polymer waveguides are "highly flexible and resistant to high temperatures," says Bert-Jan Offrein, manager of the Photonics Research Group at IBM Research in Zurich. Offrain reported that neither twisting nor deformation was observed on bends with a radius of up to 1 mm, and also under extreme operating conditions at 85% humidity and a temperature of +85°C.

Silicone allows you to use the same basic element as in CMOS crystals - silicon - but in a flexible form, which allows the beam of light to pass through bends and turns with very little distortion. As a result, very fast and energy efficient photonic interconnects can be fabricated, capable of transferring the exabytes of data required for future data centers and supercomputers.

Eric Peeters, vice president of Dow Corning Electronic Solutions, predicted that the new material will enable "on-board silicon-based communications that will quickly replace conventional electronic signaling methods."

Silicone polymer is born as a liquid like other optical materials such as glass, but when left under normal atmospheric conditions, it cures in less than 45 minutes. The material also showed excellent adhesion to traditional PCB materials such as polyimide, has a loss of no more than 0,03 dB per centimeter, remains stable for more than 2000 hours at high temperature and humidity, withstands 500 temperature cycles in the range of -18 ... +120 °C.

The presentation at Photonics West "Stable and Machinable Optical Silicone for Low Loss Polymer Waveguides" was presented by Brandon Swatowski, Project Engineer at Dow Corning Electronics Solutions.
