COVID-19 Simulations

The Washington Post publish some fantastic COVD-19 outbreak simulations showing no countermeasures, forced quarantine, social distancing with 1/4 movement and 1/8 movement. The simulations clearly show that social distancing is the most effective at reducing the amount of people that get infected, and the more social distancing the better.

True Crystal Randomness

A research team at the University of Glasgow have developed a novel way to generate true random numbers. They built an automated robot to manage chemical reactions in crystals which produce inifintely possible physical changes. The robot detects and records the changes in the crystals across multiple variables such as size, location, colour and shape and then converts the images to binary sequences.

Modelling Knot Stability

Mathematicians and engineers at MIT have developed a model that predicts the stability of a knot. The model was created by observing the pressure on knots using fibres that change colour with pressure. A simulation was then created and tested against the real world results in order to validate the model.

Stem Cell Robots

Researchers in the U.S. have created the first organic robots which measure at less than 1mm long. The living programmable organisms are first simluated using evolutionary algorithms to create random designs using combinations of different stem cell types. Successful xenobot designs are then created in real life using frog stem cells.
