What musical instrument makes sounds from the stalactites of an American cave?

In the US state of Virginia, there are the Luray Caves, where a unique musical instrument is installed - an organ made of stalactites. 37 stalactites of different tone are connected to the pipe system of a traditional organ and are controlled from a conventional organ keyboard.

How fast does hair grow?

In men who are prone to baldness, hair does not grow fast enough. Boys seem to grow hair too fast.

The rate of hair growth is actually measured and is about 12 mm per month. Hair does not grow at a certain rate every day, but still follows a certain rhythm. Hair grows slowly at night. Growth accelerates during the day. Between 10 and 11 o'clock the rate of growth is greatest. Then the decline comes again.

The peak of growth occurs between 14 and 16 hours, then growth slows down again. But these fluctuations in growth are so small that they cannot be noticed. Don't expect to see in the mirror how much your hair has grown in a given amount of time. If all the hair on the body grew the same way as on the head, then it would be possible to calculate how much hair grows on the body. Such hair would grow at 3 cm per minute, and by the end of the year they would be 59 km long. Not all people have the same amount of hair.

Blondes have thicker hair than brunettes. People with red hair have a small amount of hair, and they are less durable.

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 ... >>

The computer will write any term paper 05.03.2021

American researchers have found that artificial intelligence can write a term paper for students in just 20 minutes. The quality of such work will be sufficient to close the subject.

During the experiment, the researchers asked students to write papers on various topics: US history, law, research, and creativity. In addition to students, the same work was written by the algorithm.

On average, the AI called GPT-3 scored "satisfactory" for all essays. The algorithm coped best with works on US history and law - only one student was able to write a legal text with a higher score. But about the vaccine against COVID-19, artificial intelligence wrote the worst.

The findings of the researchers say that the algorithm wrote shallow, less descriptive compared to human texts. But it took people much longer to get the job done than GPT-3. On average, students completed the task in 3 days. In general, the feedback from teachers on the work of the algorithm and students was very similar.
