Rabbits threaten heritage

02.02.2006

Almost two thousand years ago, in 122 AD, the Roman emperor Hadrian visited Britain, which had been captured by the Romans. The authorities of the colony complained to him about the constant attacks of barbarian tribes from the still unconquered north. And then Adrian ordered to build a protective wall across the entire island.

This structure, partly an earthen rampart, partly a stone wall with a deep moat, was built in five years, with almost all the work carried out by the soldiers of the three Roman legions permanently stationed in Britain.

The surviving sections of Hadrian's Wall are considered a valuable monument of history and architecture. Now the remains of the defensive structure are threatened by rabbits, digging the wall with their holes. In places, the base of the wall is so pitted that it looks like a lunar landscape. Sooner or later the foundation of the wall will give way and it will collapse.

Archaeologists are pushing for the introduction of biological control measures against rabbits. In the 50s of the last century, the number of rabbits reached one hundred million heads, and the myxomatosis virus, a deadly disease for rabbits, had to be spread among them, which destroyed 99% of the livestock. However, now it is estimated that there are again too many of them - about 38 million.

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

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. ... >>

Greenhouse vodka 03.06.2022

The American Air Company introduced a vodka called Air Vodka made from captured carbon dioxide. Another component of the drink is water. This is just one of several new products that use CO2 emissions that can be captured in various industries.

“We have partners that we work with. They capture carbon dioxide before it goes into the atmosphere. We then use that carbon dioxide in the process of creating alcohol. With every bottle we make, carbon dioxide that would have been released is removed into the atmosphere and I think it's very good for our planet," says Gregory Constantine, co-founder of the Air Company.

The production of alcoholic beverages in the traditional way leads to the release of carbon dioxide into the atmosphere. American scientists have found that the production of one bottle of alcohol with a volume of 0,75 liters leads to the release of approximately 3 kg of carbon dioxide into the atmosphere.

Creating vodka in the traditional way not only results in emissions, but also requires a lot of water - about 35 liters per liter of distillate. At the same time, Air Vodka contains only two components: carbon dioxide and water. According to Konstantin, much less water is needed to produce this vodka.

An alcoholic drink is produced by separating hydrogen and oxygen from water using electrolysis. The hydrogen, together with separately captured CO2, is then fed into a dedicated carbon recycling system. In this case, ethanol is formed, which, in combination with water, forms a kind of vodka.

But despite the environmental benefits of such "green" alcohol production, special vodka is not cheap - $ 65 per bottle, and therefore this drink can be attributed to luxury brands of alcohol.
