Vitamin D deficiency may increase risk for addiction to opioids and ultraviolet raysLab animals deficient in vitamin D crave and become dependent on opioids, which is curbed when normal levels of the vitamin are restored. Human health records indicate that people with low vitamin D are more likely to use and misuse opioids. Study results suggest a potential role for vitamin D supplementation in fighting opioid addiction.1
Research shows potential new sunscreen is coral-safe and provides more UVB/UVA protectionA new study published in Nature Scientific Reports has found that Methylene Blue, a century old medicine, has the potential to be a highly effective, broad-spectrum UV irradiation protector that absorbs UVA and UVB, repairs ROS and UV irradiation induced DNA damages, and is safe for coral reefs. The study suggests that Methylene Blue could become an alternative sunscreen ingredient that supports the environment and protects human skin health.1
Scientists develop transparent electrode that boosts solar cell efficiencyDeveloping new ultrathin metal electrodes has allowed researchers to create semitransparent perovskite solar cells that are highly efficient and can be coupled with traditional silicon cells to greatly boost the performance of both devices, said an international team of scientists. The research represents a step toward developing completely transparent solar cells.
Data from 45 million mobile users further shows poorer people less able to stay at home COVID rulesPeople living in deprived, less affluent neighborhoods spent less time indoors at home during lockdown, according to a study that tracked data from millions of mobile phone users across the United States.
Study affirms that vaccines are safe for children and adultsA new study looking across a large body of research finds further evidence for the safety of vaccines that are Food and Drug Administration-approved and routinely recommended for children, adults and pregnant women. The meta-analysis does not address the safety of COVID-19 vaccines, but summarizes the results of 338 studies of other vaccines commonly given across the lifespan.
Scientists sound alarm about unprecedented mercury accumulation in Pacific Ocean trenchesA multi-national effort involving scientists from Denmark, Canada, Germany and Japan reports the first-ever direct measurements of mercury deposition in the deepest trenches of the Pacific Ocean, 8 to 10 kilometers under the sea, revealing unprecedented amounts of highly toxic mercury. The high mercury levels may be representative of the collective increase in anthropogenic emissions of mercury into our oceans. On the other hand, ocean trenches may act as a permanent dump.
