Scientists are not above, nor are they below, indulging in the sport of racing. This new study tells how a bunch of scientists arranged for a bunch of cells to race. Read the full article here: http://www.improbable.com/2016/06/25/insiders-tell-all-about-the-dicty-world-races/
Hello Subscribers, Jump into your race car and fasten your seatbelt, it’s time for a Dicty World Race update! Currently…
Video of amoebae of the cellular slime mold Dictyostelium discoideum as they make their way through a maze as part of a worldwide chemotaxis race selected for the Scientist Image of the Day.

The Dicty World Race is a competition between Dicty and HL60 cells navigating fast and accurately through complex mazes. Dicty and HL60 cells are models for studying human neutrophils, the white blood cells protecting us from infections. Cells from different labs will compete inside identical mazes. They are guided from start to finish by chemoattractant concentration gradients, from sources at the end of the mazes.
Fourteen participating teams engineered Dicty and HL60 cells to run through the mazes. More than 400 cells finished the race in the 3-hour observation time. HL60 cells were overall twice as fast as Dicty cells. However, Dicty cells were better at finding the shortest path through the maze.
To find the winners, we counted the first 100 cells to cross reach the end chamber, from all teams. It took just a bit over two hours to get these 100 cells.

The racing team from Medizinische Hochschule Hannover set us this picture from their training sessions. “There is no substitute for training hard” and the team led by Jan Faix won a meritorious third place in the 2014 race. (photo credit: Alexander Junemann, Christorf Franke, and Stefan Bruehmann).
