Portals exist

16.04.2019

Wormholes may exist, but they are useless. This conclusion was made by a group of scientists from Harvard.

Wormholes - "tunnels" in space. Their existence is allowed by the general theory of relativity, but so far scientists have not observed them. The specialists analyzed the hypothesis of colleagues Leonard Susskind and Juan Maldacena that particles in an entangled quantum state can be connected by wormholes.

Scientists believe that the path through a particular wormhole between the two black holes that it connects is longer than the path between them not through the hole.

As stated, in addition to possibly proving the ineffectiveness of wormholes as routes for space travel, the study can help establish a unified view of quantum gravity.

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 ... >>

Diamond transistor created 21.03.2024

Researchers in Japan have made a significant advance in semiconductor technology by creating the first diamond-based n-channel transistor. This breakthrough brings humanity closer to the development of processors capable of operating at ultra-high temperatures.

The creation of a diamond transistor represents an important step in the development of semiconductor technology, opening up new prospects for creating components that are more efficient and resistant to extreme conditions. This breakthrough has the potential to transform the field of high-tech applications and improve various fields of science and technology.

A new transistor developed using diamond has the potential to create more efficient components that can operate under extreme conditions without the need for direct cooling.

The research represents a breakthrough in the creation of semiconductor elements that are resistant to high temperatures, and expands the ability of processors to operate in various environments.

Scientists have created a transistor with two diamond layers doped with phosphorus, which increases conductivity. This n-channel layer replaces the traditional silicon layer in chips. When enough electrons pass through the transistor, they connect the two ends of the gate, which creates a 1 signal, as opposed to a 0 signal.

Diamond-based transistors are capable of operating at high temperatures exceeding 300°C, while conventional transistors lose their functionality at temperatures above 100°C. In addition, the new generation of transistors has increased resistance to high voltages, which makes them more reliable in operation.
