When someone bumps their elbow against a wall, they not only feel pain but also might experience bruising. Robots and prosthetic limbs don't have these warning signs, which could lead to further injury. Now, researchers reporting ...
Water regulation in leaves is vital to a plant's health, affecting its growth and yield, disease susceptibility and drought resistance.
Hydrogels are polymer materials made mostly from water. They can be used in a wide range of medical and other applications. However, previous incarnations of the materials suffered from repeated mechanical stress and would ...
NC State researchers are turning wood byproducts into sensory hydrogels that can react to different stimuli and, through advanced manufacturing methods, are made into sustainable, biodegradable smart materials that can be ...
Hydrogels are commonly used inside the body to help in tissue regeneration and drug delivery. However, once inside, they can be challenging to control for optimal use. A team of researchers in the Department of Biomedical ...
Many salamanders can readily regenerate a lost limb, but adult mammals, including humans, cannot. Why this is the case is a scientific mystery that has fascinated observers of the natural world for thousands of years.
A new low-cost and sustainable technique would boost the possibilities for hospitals and clinics to deliver therapeutics with aerogels, a foam-like material now found in such high-tech applications as insulation for spacesuits ...
Amembrane made from threads of a polymer commonly used in vascular sutures can be loaded with therapeutic drugs and implanted in the body, where mechanical forces activate the polymer's electric potential and slowly release ...
If you look at the numbers, South Korea does not appear to have much of a water problem. The country receives roughly 1.6 times the global mean in rainfall.
Tiny structures inspired by the shape of cactus spines allow a newly created material to gather drinkable water from the air both day and night, combining two water-harvesting technologies into one.
