Injuries
-
Presently, if someone has been involved in a potentially bone-breaking mishap, they have to be X-rayed by trained staff at a hospital. Soon, however, it may be possible for them to perform their own X-rays, using a compact device that could be located just about anywhere.

Scar tissue is an effective short-term solution to quickly patch up wounded skin, but it’s not so great long-term. A new hydrogel helps by triggering a regenerative immune response, so skin heals healthier and stronger without scarring.
-
For some time now, we've heard about scaffolding-like materials that are implanted into bone fractures, prompting the body's own bone cells to grow into them and heal the break. Now, however, scientists have developed a special bandage that may also do the job.
-
It was just a couple of months ago that we heard about an implantable material that electrically stimulates bone cells, causing them to reproduce. Now, scientists have created a similar substance that utilizes magnetism.
-
More and more, we're hearing about scaffolding-like materials that are used to help heal bone injuries. A new one is claimed to be particularly versatile, as it's inspired by Lego building blocks.
-
We've already heard about implantable materials with a scaffolding-like microstructure, that help heal broken bones by giving bone cells a place to migrate into. A new one could work even better, though, by also providing electrical stimulation.
-
A substance known as calcium phosphate cement is commonly used to repair broken bones, both holding them together and encouraging the growth of new bone tissue. Now, scientists have added carbon fibers to the material to also make it self-healing.
-
“Use it or lose it” applies to muscles, but unfortunately so does “don’t use it too much or lose it.” Now, researchers at Temple University have tested a drug that appears to reverse muscle damage from overuse injuries in rats.
-
Polysporin may be in for some serious competition, as Swedish scientists have created a healing gel that not only kills antibiotic-resistant bacteria, but also reduces inflammation within wounds. It could someday replace antibiotic-based medications.
-
When it comes to repairing bone injuries or defects, some scientists have been experimenting with what's known as bone morphogenetic protein. It does have some limitations, but those could soon be overcome through the use of a new biomaterial.
-
Although essential oils are typically associated with aromatherapy, new research indicates that medicines based on them could also help to heal skin wounds. It all comes down to a certain substance in some of the oils, that reduces inflammation.
-
When a bone-break occurs, the body floods the injury site with a healing biochemical known as adenosine. A new bandage is designed to absorb that substance, keeping it around so it can do more work.
