Converting WiFi to Electricity
Researchers from MIT and Harvard have developed the first flexible, 2D device that can convert energy from Wi-Fi into electricity. This could be used to power electronics that do not even contain batteries. The technology that converts AC electromagnetic waves into DC electricity has been around for some time, known as “rectennas”, but this is the first time it has been fabricated in a roll-to-roll process that could cover large structures, like the walls of an office building.

A Complete Cure for Cancer?
Scientists in Israel believe they have discovered the first complete cure for cancer. While most contemporary cancer treatments attack a specific target on or in the cancer cell, which is rendered inneffective if the cancer mutates, the game-changing treatment uses a combination of several cancer-targeting peptides that will not be circumvented by mutations. The drug may also reduce the sickening side-affect of many modern treatments, as most of them are caused by the drug interacting with incorrect, additional, or even non-cancerous cells. The drug will eventually be personalized, and it would be taken for a few weeks until the cancer is killed.

A More Sensitive AI
New algorithms have been developed to train AI out of some of its biases. A concern with current AI algorithms is that they can pick up predjudiced perspectives, for example security algorithms that recommend cops over-police areas of racial minorities. The new process gives human controllers a better sense of how AI are reaching their decisions, and then they can reconfigure how much weighting the AI is assigning to certain aspects of its training data. It’s possible that the new system could have biases of it’s own, but it’s an important step to ensure AI exhibits certain sensitivities when deployed in the field.
