A biological battery
Plugging into sources of energy within our body — such as heat, internal motion or metabolites — to power implanted medical devices has long been the goal of biomedical engineers. Now researchers based in Cambridge, Massachusetts have demonstrated that a sensing device embedded in the ear can be powered by the ear’s own electrochemical battery. Our auditory mechanism picks up external sounds and sends information … Continue reading A biological battery

A weighty issue
According to the Department of Health, obesity is one of the biggest health challenges we face in the UK. Although Paul Mason is an extreme case of the super obese, the situation is likely to become more common. Currently almost one in four adults and one in six children in England are obese, and the UK is already the fattest nation in Europe. If the … Continue reading A weighty issue

Metabolism
Prof. Graham Walker from MIT explains in this video below the metabolism of glucose in a living cell. He starts off by explaining how glucose molecules gets converted to pyruvate in 10 enzymatic steps, including the production of 2 ATP and 2 NADH (electron currency of a cell), in a process called glycolysis. The Pyruvate then migrates to the mitochondrion to produce acetyl-CoA and eventually to CO2 … Continue reading Metabolism
Personalized Energy
The Nocera lab at the chemistry department at MIT studies the basic mechanisms of energy conversion in biology and chemistry. On advice he received from Kurt Vonnegut: “He told me, ‘stop worrying about the planet dying. When you have a big organism and you become irritating to it, the immunological system just kicks in and kills the invading organism’. And he assured me that we have just … Continue reading Personalized Energy
