Can roses kill?

The Roman emperor Marcus Aurelius Antoninus (218-222), nicknamed Elagabalus (Heliogabalus), in order to get rid of his associates, whom he suspected of secret enemies, gathered them for a feast and ordered all exits to be locked and the entire banquet hall to be covered with roses.

The guests died, buried alive under a fragrant mountain of delicate flowers.

How fast are the trains?

The French TVG from Paris to Lyon has a speed of 260 km/h. In a test flight without passengers, he reached a speed of 515 km / h.

Japanese trains are even faster. On the segment between Tokyo and Osaka, the speed of the train reaches 300 km/h.

The fastest freight trains also run in France. Fresh vegetables are delivered from Perpignan to Paris at a speed of 140 km/h.

The longest railway is the Trans-Siberian Railway with a length of 9438 km. The entire flight from Moscow to Nakhodka lasts 8 days and 4 hours. It stops at 97 stations along the way. And the longest direct railway is in Australia. For 478 km there is not a single turn.

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. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The oldest molecule in the universe discovered 17.04.2019

The unique SOFIA flying observatory has helped scientists discover for the first time inside a planetary nebula in the constellation Cygnus traces of a combination of helium and hydrogen - two elements that existed in the universe even before the appearance of stars. The results of the observations are published in the journal.

"The absence of traces of this molecule in space was one of the biggest mysteries in astronomy. I was incredibly excited the moment we first saw it in our data set. This happy ending dispelled our doubts that we understand how the chemistry in the early universe," said Rolf Guesten of the Institute for Radio Astronomy in Bonn, Germany.

After the Big Bang, only three elements existed in the universe: hydrogen, helium, and trace amounts of lithium. However, after 300 million years, when the first stars appeared, heavier elements began to appear, born during thermonuclear reactions in the bowels of the stars.

Complex molecules, according to scientists, began to appear long before the appearance of these luminaries, at a time when the universe was simultaneously rapidly expanding and becoming colder. The first of these was helium hydride, a compound of neutral helium and a positively charged proton.

As Gesten notes, scientists have been trying to find traces of HeH+ in space for almost a century, but so far they have not been able to do this. Astrophysicists have attributed numerous failures to the fact that the oldest molecules in the universe can only be seen in that part of the spectrum that is especially well absorbed by water vapor and other molecules in the atmosphere.
Such problems do not interfere with the work of the world's only flying observatory SOFIA, a unique joint project between NASA and the German space agency DLR. It is a Boeing 747 with a 2,5-meter optical and infrared telescope installed on it. Climbing to a height of 13 kilometers allows you to make the quality of the resulting image close to the level of space observatories.

Using this telescope, Gesten and his colleagues observed the planetary nebula NGC 7027, located in the constellation Cygnus at a distance of 600 light-years from Earth. It is a kind of "funeral shroud" of a white dwarf, whose progenitor exhausted its hydrogen reserves and shed its outer shells about XNUMX years ago, moments by cosmic standards.

This nebula has long attracted the attention of scientists for one simple reason: approximately the same temperatures prevail inside it - about four thousand degrees Kelvin - that reigned in the early Universe at the time of the birth of the first molecules of helium hydride. In addition, the newborn white dwarf produces huge amounts of energy and light, which ionize the hydrogen around it and accelerate the birth of HeH+.
