Television and school grades

13.12.2005

Researchers at a university in the New Zealand city of Otago tracked how television viewing is linked to children's mental development.

Over the years, they recorded the mode of use of television in 1000 children aged 5 to 15 years, and later, when the subjects reached 26 years of age, they asked about their success in universities. It turned out that those who watched the least TV between the ages of 5 and 11 were the most likely to go to university and graduate from it. And those who, between the ages of 13 and 15, were especially fond of television programs, were most likely to drop out of school without completing their studies.

At the same time, the work of American researchers was published, confirming this dependence. It turned out that third-grade students (eight-year-olds), who watched more TV programs, wrote worse test control types of our USE.

Those who started watching TV before the age of three had worse grades in arithmetic and reading than those who did not watch TV before the age of three.

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. ... >>

Electronic helmet for truck drivers 14.04.2024

Road safety, especially for drivers of heavy construction equipment, is a top priority for engineers and scientists. In light of this, the German Fraunhofer Institute for Structural Strength and System Reliability has introduced a new product - an electronic helmet, which is designed to protect drivers from serious injury when driving construction vehicles. A new electronic helmet developed by a team of engineers from the Fraunhofer Institute opens up new perspectives for the safety of truck and construction equipment drivers. The device is capable of monitoring the level of shaking in the car cabin and warning the driver of possible danger. The basis of the helmet's operation is a built-in piezoelectric sensor, which generates electricity during physical deformation. This mechanism allows the device to respond to intense vibrations typical of construction equipment. When the level of deformation exceeds safe values, an alarm system is activated on the helmet, ... >>

Antivitamins instead of antibiotics 13.04.2024

The problem of bacterial resistance to antibiotics is becoming increasingly serious, posing a threat to the effective treatment of infections. In light of this, researchers are looking for new ways to combat superbugs. One of the promising directions is the use of antivitamins that can have an antibacterial effect. Antivitamins, although known as the opposite of vitamins, have proven to be a promising tool in the fight against bacterial antibiotic resistance. A study conducted by scientists from the University of Göttingen in Germany confirmed their potential in creating new drugs to combat dangerous infections. With the rise of antibiotic-resistant superbugs, there is a need to find alternative treatments. Antivitamins are molecules similar to vitamins, but capable of inhibiting bacterial activity without harm to the human body. At the moment, science knows only three antivitamins: rose ... >>

High-quality color laser printing without ink and toner 05.06.2017

Creating images with a record resolution to date is the result of a new color laser printing technology developed at the time by Anders Christensen's group at the Technical University of Denmark (Technical University of Denmark), Copenhagen. "Shooting" a laser beam at the surface of a material covered with an array of nanoscale plastic columns leads to changes in the nature of the surface, which begins to reflect light with a certain wavelength.

The laser beam heats the top of each nano-sized column to a temperature of 1000 degrees Celsius. Being at this temperature for several nanoseconds, the germanium layer covering the top of the columns melts and changes shape. Controlling the power of the laser makes it possible to induce various degrees of melting and, as a result, turn the columns into pixels that reflect light with a certain wavelength. The impact of low-energy laser pulses makes it possible to color the surface in blue, and an increase in power leads to the coloring of the surface in yellow and red.

Each of the columns has a diameter of several tens of nanometers, which allows you to place tens of thousands of columns per square centimeter of surface area. The images shown here were printed at 127k dpi. For comparison, the screen resolution of the iPhone 7 is 326 dpi.

Unfortunately, the gamut of colors created in this way does not shine with brightness and richness of colors. It is not possible to obtain greens and shades of blue in this way, and the resulting reds are very dull. However, researchers are already thinking about replacing germanium with silicon, which has a slightly different spectrum of light reflection. And with the help of silicon, it will be possible to obtain a green color, which, in turn, will allow printing bright full-color images.

New laser printing technology is unlikely to ever appear as a desktop printer. But it has prospects for making life easier for designers, fashion designers and people of other creative specialties. For example, automakers will be able to produce cabin interior parts on the same conveyor, which will then be laser-painted in the desired color. In addition, the new laser printing technology will make it possible to make adjustments, of course, within certain limits, to already printed images.
