Nanotechnology has been explored for significant time now, and this field is one of the most interesting branches of medicine to read about. This time, researchers took inspiration from a very unique animal - a pangolin. Its structure of the scales offers the little creature great protection with minimal mobility loss.

Though the material is quite rigid, scales structured in this form bend greatly, which facilitates control over the nanorobot. Researchers propose that these robots can assist our body in healing internal organ damage and mitigating blood loss.
You have undoubtedly heard many things about this famous greenhouse gas, but how much have you seen it? We typically use our imagination to think about the concentration of a gas, but this video offers a great visualization of CO2 concentration in the atmosphere. The video itself is a time lapse of CO2 being added over the course of the year 2021, and you can see how more and more gas fills up the surface of our planet until it fully covers every corner by the end of the year. Orange area represents fossil fuel emission, green area represents land ecosystems, and the little blue parts are related to ocean emissions. The author of the video mentions that “though the land and oceans are each carbon sinks in a global sense, individual locations can be sources at different times.”
What has AI learned this time? This time, AI identifies natural disasters by analyzing an image. Ethan Weber, developer of this AI, states that “when an incident occurs, many people post it on social media. However, finding this relevant information is difficult.” This model essentially acts as a sorting algorithm, which filters images of actual disasters from the general mass of media files. With this algorithm it will be possible to send humanitarian aid quicker, as there will be more relevant information available within a shorter time interval. The data set of this technology contains 1.1 million images of different calamities, among which are eruptions, wildfires, floods, earthquakes and other accidents. This AI can already detect floods and earthquakes with precision of around 89% and 74%, respectively.
