Whether they're caused by injury, disease or other factors, missing sections of bone can be quite difficult to replace. A new injectable hydrogel could change that, however, by transforming into a robust bone regeneration material when exposed to visible light.Continue ReadingCategory: Medical Innovations, Body & MindTags: Postech, Pohang University of Science and Technology, Bones, Hydrogels

the structures can fold and encapsulate water within the gel sheets, augmenting cooling potential via responsive geometry.
The post coral reef cooling project employs heat-absorbant underwater structures made of hydrogel appeared first on designboom | architecture & design magazine.
Salt-loaded hydrogel pulls water from the air, even in desert conditions
Posted by ArielTechGeek 637 days ago (https://newatlas.com)
Researchers have created a superabsorbent hydrogel that can pull moisture from the air in greater quantities than previously reported materials, even in desert conditions. The new material opens the door to creating an effective, sustainable method of addressing the important issue of water scarcity.Continue ReadingCategory: Materials, ScienceTags: Hydrogels, Water, MIT
Dual-action hydrogel prevents brain cancer returning in 100% of test mice
Posted by ArielTechGeek 685 days ago (https://newatlas.com)
Scientists at Johns Hopkins University have developed a treatment that could provide new hope for aggressive brain cancers. Injecting a drug-laden hydrogel into the brain after tumors have been surgically removed was found to launch a combined chemo- and immunotherapy attack that prevented the cancer from returning in 100% of treated mice.Continue ReadingCategory: Medical, ScienceTags: Hydrogels,
Electrically charged hydrogel could help heal brain injuries
Posted by ArielTechGeek 749 days ago (https://newatlas.com)
Unlike the tissue in other parts of the body, such as the skin, the neuronal tissue in the brain doesn't regenerate after being damaged. It may one day be able to do so, however, with a little help from a new type of hydrogel.Continue ReadingCategory: Medical, ScienceTags: Hokkaido University, Brain, Hydrogels, Stem Cells
Sunlight-activated "loofah hydrogel" excels at purifying water
Posted by ArielTechGeek 765 days ago (https://newatlas.com)
Although we've seen a number of systems that use sunlight to purify tainted water, their output is often quite limited. A new loofah-inspired hydrogel, however, uses sunlight to treat much more water in one go … enough to meet a person's daily needs.Continue ReadingCategory: Materials, ScienceTags: Princeton University, American Chemical Society, Hydrogels, Water, Purification, Biomimicry
Heat-activated hydrogel could stop battlefield bleeds
Posted by ArielTechGeek 811 days ago (https://newatlas.com)
When soldiers are wounded in battle, getting the bleeding under control is one of the most important life-saving measures medics can take. Due to the particular demands of doctoring in the field, however, this can be a significant challenge. A new injectable hydrogel that is activated by the body's own temperature may offer a way forward.Continue ReadingCategory: Medical, ScienceTags: Hydrogels,
Haptic hydrogel "skin" simulates touch in VR and AR
Posted by ArielTechGeek 819 days ago (https://newatlas.com)
While technology is making major strides in absorbing our eyes and ears in virtual worlds, it’s harder to engage senses like touch. Engineers at the City University of Hong Kong have now developed WeTac, a thin, wearable electronic "skin" that provides tactile feedback to users in VR and AR.Continue ReadingCategory: Wearables, TechnologyTags: Haptic, Haptics, Tactile, Gloves, Hand, Touch, VR, Vir
