Bandaged wounds should be checked for infection, but removing the bandage to check the wound may slow its healing. Australian scientists have a solution to this paradox in the form of a bandage that glows if the wound is infected.
Tiny structures made up of mechanically bound molecules can act as single molecular machines, and this is an extremely exciting field of chemical research.
If you are trying to make a wound dressing that is best suited for the human body, it would be most logical to use materials of human origin. This is the approach that German researchers used to create a bandage based on tropoelastin.
While the data on most storage devices can be read using electrical signals, the new technology encodes them in light. This allows the system to read them by simply checking whether the LED is on or off. Recently, researchers have developed a new device based entirely on perovskite that can do both at the same time.
Babies, imitating the speech of their parents, begin to babble. They, without realizing it, try to cut into the conversation. This is because there are areas in our brain that are evolutionarily predetermined for speech processing. Reading literally changes the brain and modifies it.
Perforation of the eardrum leads to pain and hearing impairment, and it is extremely difficult to correct such a defect. PhonoGraft, developed by Harvard scientists, is an implant printed on a 3D printer that can patch up damage by stimulating the growth of natural cells.
The technology of fixing the neutrino flux coming from a nuclear reactor was proposed by MEPhI scientists 50 years ago. Modern developments are being carried out on elastic coherent scattering discovered three years ago – the interaction of neutrinos with energy conservation with all nucleons at once.
The widespread use of composite materials in the creation of new generation aircraft is one of the main trends in the aviation industry. Composites can be used to manufacture the fuselage, wings, tail and other elements of the aircraft, which reduces its weight and increases strength. However, nothing is perfect: over time, the mechanical and strength properties of composite materials deteriorate, which is associated with the accumulation of damage during operation. It is extremely important to calculate exactly how this process takes place in order to increase the resource of aviation products.
Materials that change their properties in response to certain stimuli can occupy a valuable niche in many fields, from robotics to medicine and modern aircraft. A new example of such a shape-shifting technology was presented in the form of an imitation of ancient chain mail armor, which allows you to quickly switch from a flexible version to a rigid one due to the features of the material.
Stopping bleeding due to injury can save lives, but due to the abundance of blood, many patches and bandages simply refuse to stick to the skin. Researchers at the Massachusetts Institute of Technology have developed a new surgical adhesive that can stop bleeding within 30 seconds.
