Low battery? Just plug it in...to yourself
MEMS device generates power from body heat -- In an attempt to develop a power source that is compact, environmentally friendly, and has an unlimited lifetime, a team of researchers from Singapore has fabricated an energy harvesting device that generates electricity from body heat or any environment where there is a temperature gradient. Their device, called a thermoelectric power generator, attaches to the body and generates a power output of a few microwatts, which could be useful for powering implanted medical devices and wireless sensors.

Carbon Nanotubes Boost Cancer-Fighting Cells
-One defensive strategy in the human immune system utilizes T cells, which are able to detect bad stuff in the body, replicate in lymph nodes, and then induce a strong immune response.
-Tumor cells are able to survive because they prevent tumor-specific T cells from replicating and therefore suppress any immune response.
-A technique called 'Adoptive Immunotherapy' is a treatment option, where patient's blood is drawn and T cells are stimulated and replicated in the lab before being transferred back into the patient.
-A major drawback right now is that it can take several weeks until sufficient T cells are produced.
-Yale scientists have found that carbon nanotubes mimic lymph nodes in the lab and reduce the time to produce enough tumor-fighting T cells by 1/3.
-All that is needed now is find an efficient way of removing the carbon nanotubes before re-injecting the T cells into the patient.
