Cyanobacteria, like the hot-spring dwelling Nostoc sp. strain VKB02, have a unique way of dealing with the daily ups and downs of light and dark cycles. These tiny organisms have a built-in 24-hour clock that helps them adapt to changes in their environment. But what happens when the sun's ultraviol
The sun's ultraviolet (UV) rays pose a serious threat to skin health. They can cause sunburns and even lead to skin cancer. Most treatments today focus on easing symptoms, but there's a growing interest in finding new ways to tackle these issues. Enter xanthophylls, a group of natural pigments found
Ever wondered how the sun's rays affect your skin? Well, scientists have found a cool way to see the impact of UV radiation on our skin. They used a technique called digital holographic interferometry (DHI). This method helps us visualize how UV rays change the skin's surface and stiffness. This is
Sunlight can make water pollution worse. There are chemicals called polycyclic aromatic hydrocarbons, or PAHs. They are found in water and can harm aquatic life. The problem is, when UV light from the sun hits these chemicals, they can become even more toxic. This is a big deal because we don't know
You know how cancer cells can sometimes come back after treatment? Scientists found a way to use UV light to help these tough cells produce tiny delivery containers called microparticles. These microparticles can carry tiny magnetic bits, called superparamagnetic iron oxide nanoparticles (MNPs), rig
The summer may be winding down, but the risks of sun exposure remain high. The latest social media trend claiming that intentionally getting sunburned can help treat acne or rejuvenate skin is nothing short of misleading. As dermatologists Jennifer Stein and Elizabeth Berry remind us, the sun's ultr
