How many earthlings are over 100 years old?

According to statistics, about 100 people over the age of 100 now live on Earth.

The number of centenarians on our planet is growing quite rapidly, especially in countries with a high standard of living. In the United States, for example, in 1960 there were about 4 centenarians aged 100 years and older, and now there are 55 of them.

How do supporters of the Movement for the Voluntary Extinction of Humanity justify their goal?

There is the Movement for the Voluntary Extinction of Humanity, whose supporters believe that the population of our species is out of control and threatens all life on the planet. The way out of this situation, in their opinion, will be the complete extinction of Homo sapiens. To achieve this goal, you do not need to commit suicide or kill others - you just need to give up procreation.

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 ... >>

Nanoresonators will make cellular communications better 19.09.2012

In large cities, especially during mass events, problems with cellular communication are not uncommon: the network is often congested, people cannot make calls, miss incoming calls and cannot receive messages on time. Scientists at Purdue University have created tiny electrostatically powered mechanical devices that dramatically improve the performance of cell phones and other mobile devices.

Scientists have found a way to mass-produce nanoresonators that will solve many of the problems of radio networks. Currently, for a large number of mobile devices, there is often simply not enough radio frequency spectrum. To solve this problem, more accurate filters are needed that could eliminate interference and use a narrow band of a dedicated frequency for communication. Making a good tunable filter based on transistors, chokes and other "traditional" electronic components is very difficult. Another thing is nanoresonators, which also consume much less energy.

The heart of the nanoresonator is a bundle of silicon fibers about 2 microns long and 130 nanometers wide - about 1000 times thinner than a human hair. When alternating current is applied, the silicon fibers begin to vibrate from side to side or up/down. The frequency and direction of vibration can be tuned with high precision, and nanocavities are cheap to manufacture, and millions of such devices can be "packaged" into a single microchip and integrated into conventional electronics.

Nanoresonators can find application not only in communication technologies. Based on them, you can create tiny sensors to detect and measure the constituents of complex substances, such as certain proteins or DNA molecules. Nanoresonators can also be used in medical gas analyzers, the food industry, for monitoring water quality, detecting chemical warfare agents, etc.
