Technology has largely improved the quality of life for patients needing implantable electronic devices, such as pacemakers or cochlear implants. Pacemakers allow for the heart to function properly and cochlear implants restore hearing to deaf patients. The downfall of these types of technologies is the way in which they are powered. Batteries are a common power source, and while they can be designed to have lifespans of several years, they do eventually need to be replaced. One could argue that this, to an extremely small degree, undermines the benefits of having the implantable device.
Researchers at MIT may have found a way to completely remove this inconvenience associated with having an implantable electronic device. What if we used the resources in our own body to power the electronic components we put into it after injury? More
Can you hear me now? For years, it has been popular doctrine that cell phone use is bad for our brains, but we glue our phones to our ears anyway. Cell phones emit radio frequency-modulated electromagnetic fields (RF-EMFs) that are questioned for their potential danger when the brain is exposed to them. The oscillatory frequencies of RF-EMFs correspond to those measured in neural tissue, and thus could interfere with neural activity. The amount of electromagnetic radiation given off by our communication devices is small, but is radiation all the same. Radiation exposure is dangerous for any kind of cell in our body, and can penetrate cells and damage DNA either by crashing into the molecule directly or causing damage indirectly by forming free radicals from water that can have cancer-causing effects.
