Hive for wild bees

16.07.2003

The English company "Oxford Bee" has launched the production of ready-made houses for wild bees.

In recent years, honey bees in England, and in many other countries, have suffered greatly from parasitic mites. As a result, yields of crops that need pollination by bees have decreased. In this regard, honey bees can be replaced by solitary wild bees - osmia. They do not give in to a tick and, moreover, are more effective in pollination.

Osmias collect pollen on the pubescent underside of the abdomen, rather than tamping it into special baskets on their legs, like a honey bee, therefore increasing the likelihood of pollen getting onto the pistil. Importantly, osmias are distinguished by a complaisant disposition and almost never use their sting. In spring, they begin to fly earlier than ordinary bees, at a lower temperature.

In nature, osmia live in hollow reed stems, empty snail shells, in the passages of woodworms and other tubular cavities. Oxford Bee proposes to attract osmium to the gardens by hanging houses for them. The nest tubes are made of biologically neutral plastic and lined with paper. The hive can be expanded by purchasing individual tubes.

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. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

fungus against drugs 06.08.2000

At an experimental agronomic station in the Hawaiian Islands, a species of Fusarium fungus was found that affects coca bushes, from the foliage of which cocaine is obtained.

Fusarium is notorious for the owners of suburban areas, it parasitizes the roots of many cultivated plants and can completely destroy the crop. The spores of the fungus can survive for years in the soil.

The possibility of dispersing them from aircraft over those areas of Colombia where the population lives mainly on coca cultivation is being considered. It is not yet clear whether the fungus will also attack other plants, but greenhouse experiments have shown that 50 other plant species do not succumb to this Fusarium strain.

However, there are other reasons for reflection: some experts believe that the farmers, for whom coca cultivation is the only and not very labor-intensive source of income, will simply move their plantations deeper into the impenetrable rainforest.
