A monkey named Punch has captured attention for forming a strong attachment to toys, but scientists say this behavior extends across many animal species. Adult mammals often seek security and companionship through toys and objects, demonstrating emotional needs similar to those of young animals. The phenomenon highlights how animals use inanimate objects to cope with stress, loneliness, or environmental changes, providing comfort and psychological support in captivity or challenging situations.
Researchers emphasize that the brain needs continuous learning to maintain mental health, with new skills and experiences helping to prevent depression. Scientists point to childhood activities like solving logic puzzles or learning crafts that many people abandoned after initial difficulty, often concluding they lacked natural talent. Mental health experts now encourage people to reconsider these abandoned pursuits, citing Nobel Prize-winning physicist Carl Wieman's research on learning processes. The findings suggest that engaging the brain in new challenges and skill development serves as an effective preventive measure against depression, regardless of perceived natural ability or early setbacks.
Slovakia enters the astronomical spring season today as the Earth reaches the spring equinox on its orbital path around the Sun. At the moment of equinox, the Earth positions itself at a point where the plane of the Earth's equator passes through the geometric center of the Sun's disk, creating equal periods of daylight and darkness across the globe. The equinox marks the official beginning of spring in the Northern Hemisphere, with days continuing to lengthen until the summer solstice in June.
The European Space Agency has successfully reestablished contact with a vital solar observation satellite after communication was lost in mid-February. The spacecraft's coronagraph instrument lost its orientation on February 14 following a sequence of events that caused its solar panels to turn away from the Sun, depleting the satellite's batteries. The probe subsequently entered survival mode to preserve its core systems. The restoration of contact represents a crucial recovery for solar monitoring capabilities, as coronagraphs are specialized instruments designed to observe the Sun's corona by blocking out the bright solar disk, allowing scientists to study solar activity and space weather phenomena that can affect Earth's technology and communications systems.

The initiative represents an effort to expand AI literacy across various age groups and educational levels in Slovakia's third-largest city.
Research indicates that assembling puzzles offers measurable benefits for brain health, concentration, and cognitive development beyond simple entertainment. Studies suggest this popular recreational activity can strengthen mental function, with positive effects appearing surprisingly quickly. The findings add to growing evidence that puzzle-solving serves as more than just a way to relax or pass time, potentially offering a simple method for cognitive enhancement.
NASA's Perseverance rover has discovered traces of what was once a river delta on Mars, representing one of the oldest evidence of water found on the planet to date. The discovery provides new insights into Mars' ancient past, when liquid water likely flowed across its surface billions of years ago. River deltas form where flowing water meets a standing body of water, depositing sediments over time, suggesting that Mars once had conditions capable of supporting liquid water systems for extended periods.
French chemist Olivier Monfort, who researches the use of nanomaterials for wastewater treatment, says Slovakia has the capability to conduct top-level scientific research. Monfort studies the application of nanomaterials, particularly MXenes, for water purification and notes that these materials can be used for wastewater treatment practically anywhere. The scientist from Vannes in Brittany first encountered Slovakia 20 years ago during a cultural festival for young people and later completed both his master's and doctoral studies at Comenius University in Bratislava. His research focuses on advanced materials that could revolutionize water treatment processes, demonstrating Slovakia's potential as a hub for cutting-edge scientific work in environmental technology.
Slovakia's Forest Ecology Institute has issued recommendations to state agencies regarding changes to protected area zoning systems. The institute expressed confidence that the zoning processes will comply with Slovakia's nature protection legislation. The recommendations come as part of ongoing efforts to ensure proper environmental protection measures are implemented across the country's protected natural areas.
A medication previously known primarily for treating diabetes and promoting weight loss has demonstrated new therapeutic potential for joint inflammation, potentially offering relief to hundreds of millions of people suffering from arthritis and related joint conditions. The drug's expanded applications could represent a significant breakthrough in treating inflammatory joint diseases, which affect vast populations worldwide. This discovery opens new treatment pathways for patients with joint disorders who may benefit from the medication's anti-inflammatory properties beyond its established uses in diabetes management and weight control.
The Eurasian lynx population in Slovak Karst National Park is teetering on the brink of survival, according to conservation experts. The critically endangered wild cats face potential complete disappearance from the protected area in southeastern Slovakia unless immediate conservation measures are implemented. Slovak Karst National Park, established in 1973, protects a unique limestone landscape along Slovakia's border with Hungary and serves as one of the country's most important biodiversity reserves. The lynx, Slovakia's largest wild cat species, has struggled with habitat fragmentation and declining prey populations across Central Europe, making international cooperation essential for species recovery efforts.
Nvidia CEO Jensen Huang announced that the company's chip sales revenue would reach one trillion dollars by next year, but investors were unimpressed by the ambitious projection. The artificial intelligence chip manufacturer's stock price fell following Huang's presentation at a conference in San Jose yesterday. Despite Nvidia's position as a leading developer of advanced chips for artificial intelligence applications, investors apparently viewed Huang's growth projections as insufficiently rapid for their expectations. The market reaction suggests skepticism about whether the company can achieve such aggressive revenue targets in the compressed timeline outlined by its chief executive.
Robert Trivers, one of the most influential evolutionary biologists of the 20th century, has died. Trivers made groundbreaking contributions to evolutionary theory, particularly in understanding altruism, parent-offspring conflict, and sexual selection. However, his scientific legacy has been complicated by his later association with Jeffrey Epstein, the convicted sex offender who provided funding for some of Trivers' research. The connection raises questions about how to evaluate scientific achievements in light of problematic personal associations and funding sources.
Researchers have identified the oldest known case of a rare genetic disease in two women buried together over 12,000 years ago in the Grotta del Romito cave in southern Italy.

The discovery provides new insights into ancient human genetics and the presence of genetic diseases in prehistoric populations, marking the earliest documented case of this particular genetic disorder in the archaeological record.
Japanese researchers have discovered that asteroid Ryugu contains all the essential components required for the emergence of life. The findings support the soft panspermia hypothesis, which suggests that organic compounds and potentially life's building blocks can be transported through space on asteroids and other celestial bodies. The discovery adds significant weight to theories about how life might have originated on Earth through extraterrestrial delivery of organic materials. Ryugu, which was studied through Japan's Hayabusa2 mission that collected samples from the asteroid's surface, continues to provide valuable insights into the early formation of our solar system and the potential pathways for life's emergence.
Gaming companies exploit detailed player data to manipulate behavior and increase addiction risk through "dark patterns" embedded in video games, according to Slovak psychologist Marcel Martončik. Gaming companies collect extensive information about players, including when they play, how they interact with games, where and how often they click, and their purchasing behavior, Martončik explained in an interview. This detailed knowledge allows companies to use psychological manipulation techniques against players. The psychologist also addressed the popularity of games like Minecraft and discussed whether violent "shooter" games provide an acceptable outlet for aggression, as well as the potential cognitive benefits of gaming on memory.
