Some vaccines aren’t very effective, which is due at least partially to the amount of time that they’re active within the body. A new injectable hydrogel, however, could allow them to act for a longer period of time, making them more potent.Continue Re… Continue reading Gel vaccines may be more effective than currently used liquids
Heart attacks are a leading cause of death, largely because the damage caused by one can lead to more later. Now researchers at Rice University have developed a new way to repair heart tissue and reduce scarring, by implanting capsules loaded with stem… Continue reading Capsules loaded with stem cells help repair heart damage in mice
Scientists working towards next-generation treatments for blindness have made an exciting breakthrough, demonstrating how a new method of injecting healthy cells into the eyes could act as a one-two punch to address vision loss. The technique, demonstr… Continue reading Two-for-one eye cell injection boosts vision in severely blinded mice
Our brains not only memorize things, they also forget them. While that may seem like a limitation, it’s a quality that’s been copied in a new hydrogel – and it may actually have some practical applications.Continue ReadingCategory: Materials, ScienceTa… Continue reading “Memorizing and forgetting” gel mimics the human brain
Cartilage plays a crucial role in your knees, but unfortunately once it’s damaged or worn out it’s hard to repair. A replacement is often required, but these aren’t as good as the real thing. Now, researchers at Duke University have created a new hydro… Continue reading New hydrogel could work as well as real cartilage in knee replacements
Rupturing a tendon or ligament can be a devastating setback for athletes both professional and amateur, and not just for the hefty medical costs associated with treatment and rehabilitation. These types of injuries can mean long stints on the sidelines… Continue reading Hydrogel scaffold may fast-track healing of torn ligaments and tendons
Some bacteria are known to produce their own electricity, which could make them useful in batteries and fuel cells. But so far, attempts have been inefficient and inflexible. Now, researchers at Karlsruhe Institute of Technology (KIT) have created a “b… Continue reading Biohybrid battery harvests energy from electric bacteria
Slapping on a Band-Aid is the easiest way to help a cut on your skin heal, but things aren’t so simple for internal wounds. For one, it’s obviously much harder to reach that surface to put a dressing on it, but even when its open, say during … Continue reading Harvard hydrogel made by bacteria helps heal internal wounds
The most numerous of organisms on Earth, bacteriophages are viruses that infect and kill bacteria. Now, scientists have grown enough of them to create a self-healing hydrogel that’s made almost entirely of the things. It could have important … Continue reading Self-healing antibacterial gel is made of viruses
With a few experimental exceptions, bandages generally just cover wounds, as opposed to actively healing them. That’s not the case with a new heat-activated “active adhesive dressing” (AAD), however, which forgoes antibiotics while mimicking … Continue reading Hydrogel bandage uses body heat to speed wound healing
