In case you missed it (ICYMI), here are some of the stories that made headlines in the world of cleanrooms and nanotechnology in the past week:

A biochemical sensor implanted during an initial biopsy could allow doctors to do a better job of monitoring and adjusting a person’s cancer treatments. The sensor, developed by MIT, will provide a real-time, reliable glimpse into how a specific therapy is working for the patient. 

BBC Click sent a science correspondent to the Goddard Space Flight Center in Maryland to check out the James Webb Space Telescope. The JWST is being assembled in a Class 10,000 cleanroom. Click here for a video: http://www.bbc.co.uk/programmes/p02ygjjg

Manchester Metropolitan University is researching a way to 3D-print longer-lasting batteries using graphene ink. The process could help meet the growing demand for energy storage products in household devices (phones, tablets) or renewable energy systems (solar, wind, and wave power storage). Researchers hope to battle climate change by producing clean energy with these new kinds of storage systems.

Beauty is going high-tech. NBC reports that a new device can turn any image into wearable color by 3D-printing makeup. Meanwhile, Panasonic has developed a hair dryer that can style a person’s mane without turning the hair into a brittle mess.

Finally, researchers from two North Carolina universities has found that sandcastles are very similar to the way that magnetic nanoparticles — encased in oily liquid shells — are able to bind together in water. The process mimics the way that sand particles mix with water to form sandcastles.
