Girls learn faster than boys 28.04.2024

Research in the field of child development has always been of interest to science and society. However, the role of the microbiome, the body's internal ecosystem, in this process remains a poorly understood area. Recent discoveries by scientists at the University of Alberta shed light on the important influence of gut bacteria on infant cognitive development. A study conducted on 400 babies, led by Professor of Pediatrics Anita Kozyrskaya, revealed interesting patterns in the development of boys and girls. It turns out that certain gut bacteria, such as Bacteroidetes, are important for the development of cognitive and language skills in boys. “It has long been known that at an early age girls usually outperform boys in terms of cognition and speech,” explains Professor Kozyrskaya. Although differences in the microbiome between boys and girls are not significant, girls often have higher numbers of Bacteroidetes bacteria. This circumstance is probably due ... >>

Bacterial vampirism 28.04.2024

Some of the deadliest bacteria react to human blood and rush to it, since its serum contains substances that serve as food for them. American scientists studied this phenomenon, which was called “bacterial vampirism.” The Enterobacteriaceae family of bacteria includes both representatives of the normal microflora of the human body and a large number of pathogens, including salmonella and E. coli. Some enterobacteriaceae are associated with gastrointestinal bleeding and bacteremia and are considered a leading cause of death from sepsis in people with inflammatory bowel disease. However, the behavior of these microorganisms and the mechanisms that encourage them to enter the bloodstream are not well understood. A team of specialists from the University of Washington and the University of Oregon (both in the USA) took on the task of filling the gap. Researchers have found that blood serum attracts at least three types of pathogenic bacteria: Salmonella enterica, Esch ... >>

Not all carrots are equally healthy 26.04.2024

Carrots have long been recognized as one of the healthiest foods due to their beta-carotene content, a substance that is converted into vitamin A, which is essential for maintaining vision and cardiovascular health. However, recent research shows that not all people benefit equally from eating carrots due to genetic differences. Scientists at the University of Illinois studied the effects of beta-carotene on cardiovascular health, finding that its effectiveness depends on each person's genetic makeup. It turns out that the activity of the enzyme that converts beta-carotene into vitamin A varies between individuals, which determines how efficiently the body uses it. During the study, scientists analyzed blood samples and DNA from more than 700 healthy young people. They found a correlation between enzyme activity and levels of bad cholesterol, and also found that genetic variations that affect enzyme activity are associated with cholesterol levels. ... >>

Superconductor driven by magnetism 26.04.2024

Modern science strives not only to increase the efficiency of technologies based on superconductors, but also to develop methods for more precisely controlling the flow of electrons. In this context, physicists are considering new approaches based on the effect of magnetic fields on superconductivity. Recent research shows that magnetism-controlled superconductors may be possible, opening up new prospects in fields ranging from electronics to magnetic systems. One of the key advances in this field is the use of topological insulators to control superconductivity. In the past, the application of external magnetic fields could disrupt the properties of superconductors, but with the help of topological insulators, it has been possible to create an exotic state of superconductivity that can be precisely controlled when exposed to a magnetic field. The researchers were able to create a two-dimensional topological insulator using mercury, manganese and tellurium. This opened the door to opportunity ... >>

Boosting Brain Productivity 25.04.2024

Much of what we do to improve productivity involves being active—working out, having fun, or other forms of activity. But what if the secret to effectiveness lies in something more passive, like sleep? Scientists from the University Medical Center Freiburg conducted a study to find out which type of rest is most beneficial for brain recovery and increased productivity. In the experiment, which involved 66 people, scientists divided them into three groups. The first group watched a video and played table tennis for an hour. The second group spent this time sleeping. The last group was simply in a darkened room without any external stimuli. The experiment revealed that the participants in the second group who were sleeping had the greatest brain productivity. Scientists explain this by the fact that during sleep, typical brain activity occurs, which is necessary for the communication of nerve cells and its restoration. ... >>
