mini microscope

1. A microscope uses a glass lens to refract a beam of light. This role can be played by a drop of water. Set the mirror at an angle on a piece of plasticine and cover with a glass.

2. Fold the aluminum foil like an accordion to create a layered strip. Poke a small hole in the center with a needle.

3. Bend the foil over the glass as shown. Secure the edges with adhesive tape. With the tip of your finger or needle, drop water onto the hole.

4. Put a small flower or other small object on the bottom of the glass under the water lens. A homemade microscope can magnify it almost 50 times.

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 ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

All U.S. vehicles will be switched from gasoline to gas 10.02.2012

The presidents of the United States cannot decide in any way which way cars will develop and what fuel will replace motor gasoline.

George W. Bush was a supporter of fuel cells, but then changed his mind in favor of bioethanol. Barack Obama initially bet on biofuels and electric vehicles, but said this week that scientists should come up with new ways to convert vehicles to natural gas. Apparently, he wants to find a way to use the record for the last 10 years, natural gas production, the price of which in the US has already fallen to less than $100 per thousand cubic meters. For comparison, in Europe the wholesale price of gas is kept at the level of 280 dollars, and in Russia - 120 dollars.

The gas is attractive because it can be used in conventional internal combustion engines. However, unlike gasoline, liquefied gas requires an expensive heavy tank, which reduces the range of the car and scares car owners. The US Department of Energy Research Agency (ARPA-E) will soon initiate a competition to develop a low-cost way to turn natural gas into liquid fuels with high energy density. It is possible that this will be a technology for converting natural gas into synthetic gasoline, which will not even require reworking cars, but will significantly reduce the cost of fuel.

Also, the US government plans to reduce dependence on oil by encouraging the production of medium and heavy trucks that run on natural gas or other alternative fuels. For this, the relevant road infrastructure will be deployed and new car models will be developed, as well as municipal buses and trucks converted to gas. At the same time, it is planned to find new ways to convert and store natural gas.

Unlike fuel cell, biofuel and battery vehicles, natural gas vehicles are already being sold in large numbers around the world. If American scientists manage to find a way to cheaply and safely store natural gas in a car tank, we will have a boom in gas vehicles, which, however, will once again push high-tech electric vehicles into the distant future.
