The number of people with myopia is rapidly increasing, and recent studies link this not only to the use of digital devices but also to insufficient bright light during close-up work. Scientists are proposing new preventive methods, including special lenses and eye drops, but large-scale studies are still needed to confirm their effectiveness.
A new study has found that people with two or more tattoos are diagnosed with melanoma less frequently than those without tattoos. The authors urge caution in interpreting these findings and emphasize the need for further research.
An Australian study has shown that regular use of high-SPF sunscreen may lower vitamin D levels in the blood. Experts recommend taking additional vitamin D supplements if necessary, without giving up skin protection.
Scientists have developed a method for splitting hydrogen using gold, titanium, and ultraviolet light at room temperature, enabling the efficient conversion of carbon dioxide into ethylene. This technique could be applied in industry and make use of sunlight.
Recent experiments have shown that under extreme conditions, not only water but also a mixture of sulfuric acid and organic compounds can serve as a solvent for life. This broadens our understanding of possible forms of life beyond Earth.
