In the quest for a more youthful appearance, many people slather ointments on their skin or undergo injections of dermal fillers. But topical treatments often aren't very effective because they don't penetrate deep within the skin, whereas the results from injections typically last for only a few months and can be painful. Now, researchers have developed a needle-free 'exosome' treatment that reduces wrinkles in UV-exposed mice.
Read moreNature has evolved a dazzling array of materials that help organisms thrive in diverse habitats. Sometimes, scientists can exploit these designs to develop useful materials with similar or completely new functions. Now, researchers have made a durable and flexible super-water-repelling material inspired by spiky porcupinefish skin.
Read moreResearchers explore recent efforts to use everyday materials like ice, paper, and spinach as tissue scaffolds. These unconventional materials, they argue, are more functional, more sustainable, and less expensive, as well as being available around the globe and applicable to many areas of biomedical research.
Read moreA marijuana plant extract, also known as cannabidiol (CBD), is being commonly used to improve anxiety, sleep problems, pain, and many other neurological conditions. Now researchers show it may alleviate seizures and normalize brain rhythms in Angelman syndrome, a rare neurodevelopmental condition.
Read moreA group of scientists studying the ways plant-associated bacteria interact were surprised to find that strains predicted to be more sensitive to bacteria were able to coexist with aggressor strains.
Read moreBy mimicking the outer coating of pearls (nacre, or as it's more commonly known, mother of pearl), researchers have created a lightweight plastic that is 14 times stronger and eight times lighter (less dense) than steel and ideal for absorbing the impact of bullets and other projectiles.
