Hormones Can Be Released by Remote Control Using Magnetic Nanoparticles
MIT researchers can release hormones like adrenaline and cortisol from the adrenal gland by using magnetic nanoparticles. These hormones are linked to a variety of mental health disorders, including depression and posttraumatic stress disorder (PTSD). Learning to control these hormones remotely can lead to treatments for these hormone-linked mental health disorders. The study was published…

Laser Treatment Could Turn Metal Surfaces Into Rapid Bacteria Killer
Researchers have used laser treatment to alter the surface of copper and make it a rapid bacteria killer. The technique could potentially turn any metal surface into a rapid bacteria killer by just altering the texture of the metal surface. New Laser Technique The technique was developed by Purdue University engineers and the finding published…

Astronauts’ Pee May Be Used to Build Moon Bases in the Future
The urea in astronauts’ urine can act as a plasticizer for the concrete used to build moon base structures. Researchers at NASA, the European Space Agency (ESA) and its Chinese counterpart are exploring how to apply urea from the urine of astronauts to help build moon base structures. The details of their research are published…

Tiny Gyroscope 10,000 Times More Accurate Than One in Your Smartphone
Researchers have developed a tiny gyroscope that is 10,000 times more accurate than the one in your smartphone. When devices like your smartphone lose a GPS signal, a gyroscope is important to keep things on track. This is important for applications like drones or autonomous cars. However, the performance of most gyroscopes, like the one…

Device Use Sound Waves to Detect Cancer Invasion
Scientists have designed a device that uses sound waves to detect cancer invasion. The device sends sound waves through the structure surrounding cells called the extracellular matrix. The stiffness of the extracellular matrix can then be measured. Stiffening of the extracellular matrix can indicate cancer is invading other tissue. The device was developed by engineers…
