Random interesting fact from the Great Encyclopedia:

Was the first computer bug a real insect?

(English "bug" has several meanings: "bug" (in different senses) and "bug in the program" (computer slang).)

Yes and no.

Let's start with yes. In 1947, a US Navy Mark II computer in a large auditorium (without air conditioning) at Harvard University was disabled by an ordinary moth stuck between the contacts of an electromechanical relay. The operators removed the flattened insect, stuck it with adhesive tape in a technical journal with an accompanying entry, and only after that restarted the computer.

The mechanical nature of this machine made it particularly vulnerable to insect interference. Most of the early computers, such as the ENIAC ("Electronic Numerical Integrator and Computer") at the University of Pennsylvania, were already electronic and used special vacuum tubes to protect against moths.

But did the term "bug" really come from the Harvard incident? Answer: no. In the meaning of "error" or "failure" in a particular mechanism, the word was used back in the 1889th century. The Oxford English Dictionary quotes an 1943 newspaper report about how Thomas Edison "was up for the last two nights trying to find a 'bug' in his phonograph." The XNUMX edition of Webster's Dictionary also gives the word "bug" in its modern sense.

Despite what numerous websites and books tell us, the term "debugging" was used long before the Harvard moth stalled the move of things.

Quite a telling example: life imitates language - a revived metaphor, literally.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Synthetic molecules destroy allergies 10.11.2012

Scientists have figured out how a synthetic molecule can destroy the complexes that cause allergic reactions. This discovery could lead to a very powerful development of fast-acting drugs to treat a range of acute allergic reactions. The research was carried out by scientists from Stanford University Medical School and the University of Bern, Switzerland.

A new inhibitor disarms IgE antibodies - key players in acute allergies. It separates antibodies from their chemical partners, molecules called FcRs.

"It would be incredibly fortunate if you could quickly turn off IgE antibodies in the midst of an acute allergic reaction," said Dr. Ted Zardecki, professor of structural biology and research team leader. However, it turned out that the inhibitor used by scientists does just that.

A wide variety of allergens, ranging from pollen to peanut butter, can cause an allergy in a matter of seconds by provoking IgE antibodies. The new synthetic inhibitor destroys the complex that binds IgE to FcR - the cells responsible for the reaction. Breaking that connection is the veritable Holy Grail for dealing with allergies.

"If you separate IgE from FcR on the surface of mast cells - immune cells of connective tissues - this will save a person from an allergic reaction," the authors of the study say.

As a result, a protein macromolecule was created, named by the creators of DARPin E2-79. It not only blocks the formation of new IgE-FcR complexes, but also actively decomposes already formed ones. And all this happens in just a few seconds. In addition, the molecule turned out to be small, but effective, which was a big surprise. The fact is that drug developers usually expect large macromolecules. And it seemed to them that E2-79 would turn out to be less powerful than small molecules of inhibitors, and would hardly be able to destroy the complexes. So the fact that the E2-79 worked so well came as a surprise. In addition, small molecules are more suitable for oral administration, as well as cheaper and easier to manufacture than large macromolecules.
