A single dose of psilocybin can produce lasting changes in a person’s values in life, including increased appreciation for life and deeper self-acceptance. These lasting changes appear to be caused by certain acute effects of the drug, particularly the deep feelings of togetherness and euphoria. The results of this study were recently published in the Journal of Psychopharmacology. Psilocybin is an active chemical found in certain types of mushrooms. This is a classic psychedelic drug that temporarily alters human perception and mood. This chemical primarily works by binding to specific serotonin receptors in the brain. Serotonin is a chemical messenger…
A new study suggests that as stars age, they may be killing off the giant planets they orbit closest to. The study, led by astronomers from University College London and the University of Warwick, provides new evidence that these planets can be pulled inward and destroyed as their host stars evolve. Stars like our Sun will eventually run out of hydrogen fuel. When that happens, they begin to cool and expand, entering a stage known as a red giant. Scientists estimate that the Sun will reach this stage in about 5 billion years. The new discovery is Royal Astronomical Society…
New research published in Journal of social and personal relationships Parents and their adult children have been shown to often share similar preferences regarding the characteristics they look for in future spouses in younger generations. This study suggests that these shared values, particularly an emphasis on economic security, are strongly associated with the type of parenting children experience as they grow up. Choosing a life partner requires balancing personal romantic desires and family expectations, which tends to create tension between parents and children. According to evolutionary theory, adult children prefer traits associated with physical vitality and health, which are indicative…
A group of undergraduate students at the University of Chicago used data from the Sloan Digital Sky Survey (SDSS) to identify one of the oldest known stars in the universe. This star was not born in our galaxy. Instead, it formed in a nearby companion galaxy and later migrated to the Milky Way. The discovery was made by 10 students enrolled in the university’s Astrophysics Field Course, led by Professor Alex Gee, deputy project scientist at SDSS-V, and graduate teaching assistants Hilary Anderes and Pierre Thibodeau. How big data led to major discoveries SDSS is a global collaboration involving more…
Discovered in 2011, MXenes are a rapidly expanding family of ultrathin inorganic materials. They are made from a stack of transition metals combined with carbon or nitrogen, with atoms attached to their outer surfaces. These surface atoms are not just decorative. These play a central role in how the material behaves. “They have a strong influence on how electrons move through the material, how stable the material is, and how it interacts with light, heat, and the chemical environment,” explains Dr. Mahdi Ghorbani-Asl from the HZDR Ion Beam Physics and Materials Laboratory. Until now, most MXenes have been manufactured using…
A new drug has been found to significantly lower blood pressure in people whose blood pressure remains dangerously high even after taking multiple existing drugs. The findings come from a phase III clinical trial led by UCL professors. Approximately 1.3 billion people worldwide suffer from high blood pressure. In almost half of these cases, symptoms are not controlled or do not respond well to treatment. This significantly increases your risk of heart attack, stroke, kidney disease, and premature death. Around 14 million people in the UK alone live with high blood pressure. Large-scale international trial of baxdrostat The international BaxHTN…
The meteorite impact may have done more than reshape the Earth’s surface. New research suggests they may have created the high-temperature, chemical-rich environment necessary for life to begin. “From a scientific perspective, no one knows how life emerged from the early Earth, where no life existed,” said Shea Cinquemani, who earned a bachelor’s degree in marine biology and fisheries management from the Rutgers School of Environmental and Biological Sciences in May 2025. “How does something come from nothing?” Cinquemani led a scientific review published in the Journal of Marine Science and Engineering examining where life may have first appeared. The…
How can doctors destroy cancer cells without damaging healthy tissue? This question remains one of the biggest challenges in modern oncology. Researchers at the University of Geneva (UNIGE) have developed a “smart” system built from synthetic DNA strands that can identify cancer cells with remarkable precision and release powerful drugs only where they are needed. This approach points to the future of programmable and responsive medicines in addition to cancer treatment. Here are the findings: nature biotechnology. Targeted therapies are already reshaping cancer treatment by delivering drugs directly to tumors, reducing damage to healthy cells and helping to alleviate the…
Saturn’s magnetic field does not form a balanced, symmetrical bubble like Earth’s. In fact, a new study involving scientists at University College London (UCL) shows that the variation is striking. The study suggests that this distortion is caused by the planet’s rapid rotation and the large amount of material it drags through space. The planet’s magnetic field (magnetosphere) acts as a protective shield, blocking the flow of highly charged particles from the solar wind. Saturn’s magnetosphere is huge, spanning more than 10 times the diameter of Saturn. Cassini study identifies Saturn’s magnetic cusp The survey results are nature communicationsbased on…
