Instead, the researchers say, the cells can pass on the pigment to new cells when they die. The study suggests ways to improve the ability of laser surgery to remove unwanted tattoos. Green tattoo pigment is taken up by dermal macrophages (left). The pigment is released when these cells are killed (center) but, 90 days later, is taken back up into new macrophages that have replaced the old ones (right).

This UV light could provide powerful check on influenza epidemics According to the researchers, the use of overhead “far-UVC” light in public spaces could provide a powerful check on seasonal influenza epidemics, as well as influenza pandemics. FITNESS   Updated: Feb 11, 2018 11:52 IST Indo Asian News Service According to the researchers, the use of overhead “far-UVC” light in public spaces could provide a powerful check on seasonal influenza epidemics, as well as influenza pandemics.(Shutterstock) Researchers have found that continuous low doses of “far ultraviolet C” (far-UVC) light can kill airborne flu viruses without harming human tissues. According to the researchers, the use of overhead “far-UVC” light in public spaces could provide a powerful check on seasonal influenza epidemics, as well as influenza pandemics. “If our results are confirmed in other settings, it follows that the use of overhead low-level far-UVC light in public locations would be a safe and efficient metho...

 Feb. 9, 2018   •   By  Jim Scott CU Boulder researchers have developed a new type of malleable, self-healing and fully recyclable “electronic skin” that has applications ranging from robotics and prosthetic development to better biomedical devices. Electronic skin, known as e-skin, is a thin, translucent material that can mimic the function and mechanical properties of human skin. A number of different types and sizes of wearable e-skins are now being developed in labs around the world as researchers recognize their value in diverse medical, scientific and engineering fields.   The new CU Boulder e-skin has sensors embedded to measure pressure, temperature, humidity and air flow, said Jianliang Xiao, an assistant professor in CU Boulder's  Department of Mechanical Engineering  who is leading the research effort with Wei Zhang, an associate professor in CU Boulder's  Department of Chemistry and Biochemistry  as well as a facult...

I’m a big fan of music, and use it a lot when working, but I had no idea about how it really  affects our brains and bodies . Since music is such a big part of our lives, I thought it would be interesting and useful to have a look at some of the ways we react to it without even realizing. “Without music, life would be a mistake” – Friedrich Nietzsche Of course, music affects many  different areas of the brain , as you can see in the image below, so we’re only scratching the surface with this post, but let’s jump in.

Happy/sad music affects how we see neutral faces: We can usually pick if a piece of music is particularly happy or sad, but this isn’t just a subjective idea that comes from how it makes us feel. In fact, our brains actually respond differently to happy and sad music. Even short pieces of happy or ...
