In which insects does the male have to pierce the female with his sexual organ before mating?

Bed bugs mate by traumatic insemination. This means that the female, in principle, does not have a genital opening, and the male has to pierce her abdomen with his genital organ, introducing sperm there.

Authors: Jimmy Wales, Larry Sanger

What is the name of Doctor Watson?

The name of Doctor Watson is mentioned four times in the works of Arthur Conan Doyle. In A Study in Scarlet and two other stories, he appears as John H. Watson, but in The Man with the Split Lip, his wife calls him James. There is an opinion that this is just Doyle's mistake, but creativity researchers have another hypothesis: James is a variation of the middle name of Dr. Hamish (Hamish).

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Phone guide 19.10.2006

A curious service for tourists introduced in Singapore. Walking, you saw an interesting architectural monument and want to know the details - what kind of building it is, when and by whom it was built, and so on.

You take a picture of a building with your cell phone camera and send it to the central computer of the local cell phone provider. The computer determines your location by the number of the base station with which the phone has contacted, and searches its collection of photographs (more than 2800 buildings, statues, natural and other attractions) for the object you are standing near. After that, the phone receives all the information about the object you are interested in.

In the future, the collection of images will be expanded, and the phone will even be able to tell a tourist who gets lost in a large store, office center or museum how to get out of a huge building. It will be enough to photograph some noticeable detail of the interior where you are.
