During the performance of whose opera two conductors in different years died of a heart attack?

In 1911, the Austrian conductor Felix Motl suffered a heart attack and died in hospital 11 days later. In 1968, German conductor Josef Keilbert fell dead from a heart attack.

Where were mammoth bones revered as the relics of a Christian saint?

One of the martyrs revered by Christians is Saint Christopher, who, according to legend, lived in the 3rd century and was of enormous growth. In the Orthodox tradition, he was depicted on icons with the head of a dog or a horse, among Catholics - in the form of a giant carrying Christ across the river. In Valencia, a mammoth tooth was venerated as part of his relics, and a mammoth femur as the hand of St. Christopher was solemnly carried through the streets with prayers for rain.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Global warming will hit the US especially hard 11.06.2006

A detailed model of climate development by the end of this century, created on American supercomputers, taking into account factors that could not be taken into account earlier, shows that the US climate will change almost catastrophically in the next 80-90 years.

Throughout the country, summers will become significantly hotter, winters will shorten. In the southwest of the United States there will be a shortage of water for people, livestock and crops, on the Gulf Coast it will become hotter and more rainy. The northwest will suffer from the heat. Change can be detrimental to the economy.

To test the reliability of the model's predictions, computers fed the same weather data from 1961-1985 and calculated the US climate for 2005. The match is almost complete.
