How did Dalmatians (a breed of dog) help firefighters during the horse-drawn era?

The Dalmatian breed of dog was bred at one time to accompany (guard) postal carriages. Since these dogs are able to run long distances, are accustomed to horses, and their bright white coat with black spots is clearly visible, firefighters chose them to run in front of the fire wagon and clear the way, warning by their bark to gaping passers-by.

What was the function of the $1000 I Am Rich iPhone app?

In the early days of the App Store, the app store for the iPhone, it had an app called "I Am Rich" worth $1000, the maximum price allowed. The app didn't do anything useful, only displaying a glowing red crystal and the text: "I'm rich. I deserve it. I'm successful, healthy, and happy." Apple removed the app a day later, but during that time eight people managed to buy it, only two of whom then issued a refund. Today, several similar apps are available for a maximum price of $200 on the Google Play store for Android smartphones.

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 ... >>

Why is a teddy bear dangerous? 09.05.2006

Plush toys can accumulate potentially dangerous air pollution.

The stuffing of these toys is almost identical to materials used in chemical laboratories to clean the air of harmful gases and then analyze them, says Caitlin Gorbitt of Chatham College in the UK. She and her colleagues examined the outer fabric and padding of 11 soft toys, testing for 13 pesticides and 7 flame retardants.

Most toys contained a wide range of chemicals with the greatest concentration on the outside rather than in the stuffing. It is possible that the toys were sprayed with fire extinguishers during manufacture, and "during operation" they absorbed other pollutants from the air. The content of toxins in toys made using recycled materials is especially high.

Most toys even contained remnants of the long-banned insecticide DDT. Apparently, soft toys should be washed regularly.
