When Europe Was Deserted

16.03.2000

As new studies by paleobotanists and geologists from the University of Utrecht (Netherlands) have shown, about 250 million years ago some kind of catastrophe occurred in Europe, due to which the huge coniferous forests that covered the continent before died out.

In geological deposits, the number of fungal spores that live on dead wood has greatly increased. And again, living trees did not appear until five million years later. The cause of this mass extinction remains a mystery, although it is known that at that time the level of the oceans dropped dramatically and temperatures rose. Numerous volcanoes ejected about two million cubic kilometers of lava, which covered much of Siberia.

Not only forests died, but 95 percent of all species of organisms - more than in the extinction of dinosaurs, which occurred 65 million years ago. Perhaps almost all life was killed by suffocating volcanic gases.

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. ... >>

Recyclable printed circuit boards 03.05.2024

Electronics play a key role in today's world, but the accompanying rise in e-waste is putting the environment at risk. In response to this problem, researchers at the University of Washington have developed an innovative technology that could change conventional wisdom about circuit board recycling. A team led by scientists from the University of Washington has created a vitrimer printed circuit board that has the unique ability to be recycled multiple times. Using advanced environmentally friendly polymers, the researchers developed a material that can be turned into a jelly-like substance using a special solvent. This opens the way for PCBs to be reused and recycled without significant loss of quality. Vitrimer printed circuit boards (vPCBs) represent significant advances in environmental sustainability. Unlike conventional plastics, which are susceptible to degradation during repeated recycling, jelly-like vitrimer retains its ... >>

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

4K display with ultra-wide color gamut 03.06.2015

NHK (Science & Technology Research Laboratories, STRL) has created a 50-inch 4K liquid crystal display with a record wide color gamut, that is, capable of displaying the maximum number of shades. It uses a laser LED backlight in three primary colors.

When creating a display in STRL, the goal was to get a device capable of displaying the colors of the space defined by the ITU-R Recommendation BT.2020 specification. The BT.2020 standard for 4K and 8K displays was developed with the active participation of NHK.

The BT.2020 color space is approximately 70% wider than ITU-R Recommendation BT.709, standardized high-definition television, and wider than Adobe RGB and NTSC. So far, it has not been possible to create a display that covers it completely, even using OLED and quantum dot technologies. Note that the display in question also does not fully cover BT.2020, but is close to it - coverage is 98%.

When comparing the new display to displays spanning the BT.709 space, STRL says the difference is visible in green, cyan, and green-blue hues.
