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. ... >>

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 ... >>

Laziness is good for humans 14.02.2024

Scientists from Florida Gulf Coast University have concluded that intellectually gifted people tend to lead less active lifestyles. Moreover, research shows that people who are actively involved in sports do not always have a high level of intelligence. Experts believe that excessive activity is due to the inability of many people to find activities for their minds. “Laziness can be a sign of intelligence: many people simply like to think while sitting on the couch,” say scientists. These conclusions are based on the results of an experiment in which 60 students participated. The researchers carefully studied the participants' lifestyles and assessed their level of intelligence. It turned out that people with low intelligence quickly get bored when alone and try to find something to do. Thus, the relationship between intelligence level and activity level may be ambiguous. Research has shown that intellectually gifted people may be more sedentary, ... >>

Turning water into metal 14.02.2024

Water is not a natural conductor of electricity unless it contains impurities that allow current to pass. However, pure water can only become "metallic" under extremely high pressure, which is difficult to reproduce in laboratory conditions. But a few years ago, researchers discovered that metallicity in pure water can be induced through more than just extreme pressure. The process can be started by combining pure water with an alkali metal such as an alloy of sodium and potassium. In this case, conductivity only lasts for a few seconds, but this is a significant breakthrough for science. "The phase transition to metallic water can be seen with the naked eye. The silvery drop of sodium and potassium begins to become coated with a golden film, which looks amazing," says physicist Robert Seidel from the Helmholtz Center for Materials and Energy in Berlin. Under sufficiently strong pressure, almost any material can become a conductor, like ... >>

Tomatoes grow and dry on a branch 13.02.2024

Israeli food technology company Supree has developed a unique tomato variety whose skin has microscopic cracks. As the fruit ripens, these cracks widen, allowing moisture to naturally evaporate from the fruit.

When a new tomato variety is dried, it loses about 80% of its original weight, allowing flavor, antioxidants and other nutrients to be concentrated in the remaining 20%. These tomatoes can also be dried, frozen and stored for up to a year without adding preservatives, still retaining their taste, texture and nutritional value. Supree currently focuses on supplying tomatoes directly to corporate clients in the food industry. The company is also working on a mechanized harvesting system that should reduce the cost of tomatoes and could also be adapted ... >>

New type of magnetism discovered 13.02.2024

A team of researchers from ETH Zurich in Switzerland has made a discovery that revolutionizes the understanding of the properties of magnetism in synthetic materials. The experiment was carried out on atomically thin meshes of two different synthetic materials, stacked and forming a moiré pattern. Widely studied to understand quantum phenomena, these materials have attracted the attention of the scientific world. Traditionally, magnetism has been explained by the spin rotation of electrons as a collective process. But the new discovery reveals so-called "kinetic" magnetism, which arises from electrons competing for space in a material. The experiment involved atomically thin layers of molybdenum diselenide and tungsten disulfide. When voltage was applied to the structure and irradiated with an electron beam, the material became magnetic. However, it is interesting that magnetism appeared only with a significant excess of electrons. This amazing phenomenon, called the "kinetic" magnetism of Nagaoka, was predicted by the Japanese ... >>

Deciphering the Charred Herculaneum Scrolls 12.02.2024

Almost two thousand years ago, the eruption of Vesuvius covered the ancient city of Herculaneum, leaving behind a huge treasure - a library buried under a 20-meter layer of ash. Although some scrolls were discovered, most remained unreadable until recently when artificial intelligence came into play. Brent Seales' lab at the University of Kentucky has spent years developing a "virtual deployment" method for deciphering ancient texts. By combining digital scanning with microcomputed tomography - a non-invasive technique often used in medicine to visualize cancerous tumors - and segmentation to create digital images of pages, experts were able to "read" texts, complementing them with texturing and flattening techniques. For this purpose, Seales developed Volume Cartography software, which in 2016 helped the team uncover the contents of the En Gedi scroll, found on the shores of the Dead Sea. However, the scrolls from Herculaneum presented ... >>
