Conveying empathy through social interaction 27.02.2024

Scientists have made a discovery: empathy and compassion can spread through social interaction. That's according to a new study by an international team of scientists who conducted four separate experiments involving more than 50 volunteers to study changes in empathy. Participants' ratings showed that empathy levels, based on both self-reports and brain scans, changed after observing others' reactions. This suggests that caring for others can be contagious in society if enough people demonstrate it. “Depending on whether people were empathetic or not, empathy levels increased or decreased,” explains neuroscientist Griet Hein from the University of Würzburg in Germany. In each of the four experiments, empathy was measured after watching a video of a person being subjected to painful hand stimulation. Participants were then shown videos of other people reacting to the same videos, and again from ... >>

Memory module for smartphones UFS 4.0 1 TB 27.02.2024

Micron has announced the release of its smallest UFS 4.0 flash memory module, measuring just 9 by 13 millimeters. Memory capacity remains at 1 TB, and maximum read and write speeds reach 4300 and 4000 MB/s, respectively. This module is intended for use in future flagship smartphones. It is based on 232-layer 3D NAND memory developed jointly by Micron laboratories in the US, China and Korea. This made it possible to free up additional space inside the case for installing more capacious batteries, which became a request from manufacturers. Micron engineers managed to reduce the size of the UFS 4.0 chip by 20% compared to the previous 11 by 13 mm model, which was introduced in June last year. This allowed us to reduce power consumption without losing performance. In addition, Micron introduced a new feature called HPM (High-Performance Mode) - a patented technology that improves performance ... >>

The value of pessimism in risk assessment 26.02.2024

In our time, the cult of optimism is considered the ideal. Phrases like “Why are you so pessimistic about life?” often sound like a reproach, and the term “pessimist” has acquired a negative meaning. However, an experiment conducted at the University of California at Berkeley involving more than 30 participants revealed interesting results: optimism often prevents people from making thoughtful decisions. Optimists often overestimate their capabilities, relying on luck and risking their finances and well-being. Similar findings are confirmed by researchers from the UK, noting that optimists' brains strongly filter information related to risks and mistakes. This area of ​​the brain, which is responsible for assessing risks, is less active in optimists, which leads them to underestimate possible risks and not pay attention to negative consequences. Unlike optimists, pessimists carefully assess risks and often have a backup plan in case of failure. Research has also shown that people perform better on tasks when they take action. ... >>

The skin is most damaged by smoking and ultraviolet radiation. 26.02.2024

Scientific work demonstrates the need for a conscious attitude towards factors affecting skin condition. Avoiding exposure to tobacco smoke and UV rays is key to maintaining healthy, youthful-looking skin. The skin aging process is a complex process that is influenced by both internal and external factors. In recent years, it has become known that exposure to various external factors can have a significant impact on the condition of the skin. However, little was known about the interaction of these factors with each other. The purpose of the study was to study the effect of the combined action of tobacco smoke and ultraviolet rays on the skin. The study used skin substitute models that were exposed to t ... >>

The molecular mechanism of hibernation in mammals has been discovered 25.02.2024

An international team of scientists has unraveled the molecular processes underlying hibernation in a variety of animal species, including both small and large mammals. The study found that the muscle contraction protein myosin plays a key role in the process of thermogenesis during hibernation, when heat is generated independently of muscle activity. In small mammals, cellular energy consumption increases in response to cold, allowing them to maintain core body temperature without shivering. In contrast, large mammals do not show such changes. Studying the molecular mechanisms of hibernation in animals allows us to better understand how they adapt to temperature changes and maintain vital functions during periods of reduced activity. The results obtained open new horizons for biological research aimed at studying the adaptation of animals to changing environmental conditions. Small animals that hibernate experience ... >>

Efficient solar cells made from multiple hemispheres 25.02.2024

Solar panels typically have a flat structure to absorb as much sunlight as possible, working best when the rays hit them at a certain angle. New research claims that creating tiny domes on the surface of solar cells can increase their efficiency by 36% and 66%, depending on the polarization of the light. In this case, the light will be captured at a wider angle - up to 82 degrees. The presented development has significant potential for the development of more efficient solar cells that can overcome traditional limitations and find application in various fields where a reliable source of energy is required. Scientists have previously experimented with different surface shapes, including incorporating spherical silica nanoshells to capture more sunlight and extract more energy from it. For the new study, a team from Abdullah Gul University in Turkey conducted sophisticated modeling of how dome-shaped protrusions ... >>

The ultrasonic sticker will allow you to see through the skin. 24.02.2024

Engineers from the Massachusetts Institute of Technology (MIT) have developed a revolutionary ultrasound sticker to track the health of patients' internal organs. This small device, about the size of a postage stamp, is attached to the skin and allows you to monitor the condition of internal organs, identifying signs of diseases such as liver or kidney failure, and also monitor the development of tumors. The new product is capable of directing ultrasonic waves through the skin, reflecting from internal organs and returning to the sticker. "When some organs are diseased, they can become harder," said MIT mechanical engineering professor Xuanhe Zhao. The ultrasound patch can continuously monitor organ stiffness for 48 hours, with sufficient sensitivity to detect minute changes that indicate disease progression. For example, when tested on rats, the sensor quickly detected early signs of acute liver failure. ... >>

Second sound in a superfluid liquid 24.02.2024

In most materials, heat dissipates, but in rare states of matter it can behave like a wave, moving back and forth. Scientists from the Massachusetts Institute of Technology have for the first time obtained direct images of this phenomenon, which physicists call "second sound." The discovery of second sound in a superfluid liquid opens new horizons in understanding thermal conductivity and the behavior of matter under extreme conditions. This research not only expands our knowledge of physical processes, but also may lead to new technological breakthroughs in various fields of science and technology. The images obtained by scientists showed that heat moves like a wave, “swinging” back and forth, while physical matter behaves completely differently. The team examined a cloud of lithium atoms cooled to temperatures close to absolute zero to visualize this phenomenon using a new thermography technique called heat mapping. These discoveries will help physicists better ... >>

Trees grow faster at night 23.02.2024

A study by an international team of scientists has shed light on the growth process of trees, revealing that the main period of active growth occurs at night. They observed 170 trees in different regions of Switzerland and found that the plants grew even in moderate drought conditions, provided the air was humid. Interestingly, exposure to dry air had a stronger effect on growth than dry soil. Dry air led to more intense transpiration, which led to loss of moisture from plants. When plants lose more water than they absorb, their ability to retain water is reduced, causing growth to stunt. The scientists collected a massive amount of data, including 60 million measurements of trunk radius and air and soil humidity, which helped them better understand the relationship between environmental conditions and plant growth. Ultimately, these discoveries may help to better understand the natural processes that occur in forests and gardens, and ways to optimize ... >>

Artificial piglets - organ donors for humans 21.02.2024

Japanese scientists have been able to create genetically modified piglets whose organs can be used for human transplantation. PorMedTec has been able to produce three genetically modified piglets whose organs are suitable for transplantation into humans. These organs have a lower risk of rejection. Scientists from the American biotechnology company eGenesis created piglets by transferring cell nuclei into eggs, which made it possible to obtain genetically modified embryos. The embryos were then transferred into the uterus of a surrogate pig, resulting in the birth of cloned piglets. In February, three piglets were born via caesarean section. They were made with 10 different genetic changes that are believed to help prevent organ rejection if they are transplanted into humans in the future. Upon reaching maturity, the piglets will be transferred to scientific institutions in Japan for research. These studies will determine whether ... >>
