Blinking of the magician and his audience 19.05.2024

Magic and illusions have always captured the attention of the public, but what happens behind the scenes of the magician and in the brains of his audience? Scientists from the UK decided to solve this mystery by conducting a new study involving ten illusionists of varying experience. Illusionists, some of whom had been practicing magic for more than half a century, others for only six months, were invited to demonstrate the same trick - the popular coin trick. Recordings of their performances during training and on stage showed that each of them began to blink significantly more often at the moment of performing the trick. The study's findings indicate that magicians' blink rate may be related to unconscious aspects of their performance. At the same time, as scientists have found, spectators also begin to blink more often, following the movements of the illusionist. This observation supports the idea that magicians may be catalysts for blinking in audiences. Additional research has shown that magicians blink more often during ... >>

Ultrasonic coffee machine 19.05.2024

Iced coffee has become an integral part of coffee culture in recent years. Therefore, engineers from the University of New South Wales decided to improve its preparation. They have developed an ultrasonic coffee machine that reduces the cold brew time for ground coffee beans from 12-24 hours to significantly less time. Iced coffee, or "Cold brew", is popular due to its smoothness, low acidity and low bitterness. It is prepared by steeping ground coffee in cold water for a long time. Unlike traditional hot brewing, which often imparts bitterness to coffee, cold brewing extracts more delicate and complex flavors from the coffee beans. The innovative system, presented by a team of engineers, introduces ultrasonic technology into the coffee preparation process. The system uses ultrasonic waves to speed up the process of extracting oils, flavor and aroma from ground coffee. This allows you to significantly reduce the time ... >>

The speech of sperm whales is similar to that of humans 18.05.2024

In the world of the ocean, where the mysterious and unknown coexists with the studied, sperm whales, with their huge brains, are of particular interest to science. Researchers, working with a huge array of audio recordings collected during the Dominica Sperm Whale Project (DSWP) - more than 8000 recordings, seek to unravel the secrets of their communication and understand the structure and complexity of the language of these mysterious creatures. By studying in detail the recordings of 60 sperm whales in the eastern Caribbean, scientists have revealed surprising features of their communication, revealing the complexity of their language. "Our observations indicate that these whales have a highly developed combinatorial communication system, including rubato and ornaments, which indicates their ability to quickly adapt and vary during communication. Despite significant differences in evolution, sperm whales have elements in their communication that are characteristic of human communication," says Shane Gero, a biologist at Carleton University and director of the CETI project.

Link found between gluten intolerance and cystic fibrosis 04.12.2018

An international research team from Italy and France has discovered a new "culprit" in the development of celiac disease - a mutation in the gene for the transmembrane regulator of cystic fibrosis. The discovery allows the development of therapeutic approaches for the treatment of celiac disease.

Celiac disease is a severe bowel disorder caused by damage to the villi of the small intestine from certain foods that contain certain proteins. Among these proteins, gluten (gluten) is a substance found in wheat, rye and barley.

Some people are genetically predisposed to this disease, but the mechanism of the disease is triggered by external factors. When people with celiac disease eat a diet containing gluten, their immune system triggers a response against their own cells, damaging the lining of the small intestine. About 1 in 100 people suffer from celiac disease, and it most often occurs in patients suffering from an inherited disease such as cystic fibrosis (cystic fibrosis). "This coincidence made us wonder if there is a link between the two diseases at the molecular level," said Luigi Mayuri from the University of Eastern Piedmont (Italy).

Cystic fibrosis is characterized by the accumulation of a thick layer of sticky mucus in the patient's lungs or intestines. This disease is caused by mutations in the cystic fibrosis transmembrane regulator (CFTR) gene. The eponymous protein, regulated by this gene, is involved in the transport of chloride ions across the cell membrane and plays an important role in maintaining the level of mucous fluid - when it fails, the mucus becomes clogged. In addition, CFTR failure causes a number of additional reactions in the lungs and other organs, including the intestines, by activating the immune system. These effects are very similar to the body's responses to gluten in celiac patients. Scientists have taken a closer look at the molecular basis of these similarities.

Gluten is difficult to digest, so relatively long protein parts - peptides - enter the intestines. Using gluten-sensitive human intestinal cell lines, the researchers found that one specific peptide, P31-43, directly binds to CFTR and impairs its function.

Moreover, it appears that the interaction between P31-43 and CFTR can be interrupted by a CFTR amplifier called the VX-770. To test this, scientists conducted an experiment. First, they implanted VX-770 into intestinal cells or into tissue samples collected from patients with celiac disease. Then they were exposed to P31-43 - and the peptide did not cause an immune response. Thus, the researchers concluded that VX-770 protects gluten-sensitive epithelial cells from the harmful effects of gluten. In addition, the researchers found that VX-770 could relieve gluten-sensitive mice from symptoms of intestinal disease caused by the protein.

So far, there is no cure for celiac disease. The only therapeutic strategy is to follow a strict diet. However, the current study is a promising step towards the development of a suitable therapy. Drugs that have been developed to treat cystic fibrosis could also be explored as a starting point for drug development for celiac disease, the study found.
