Modelling Thermodynamics in BioDynaMo

 BioDynaMo provides an excellent basis for the modelling of cells responding to cooling and thawing during cryopreservation, this is due to BioDynaMo’s ability to create agent based simulations where by each individual cell can act independently of those around it based on local environmental factors.


Currently through the use of behaviors within BioDynaMo, one can simulate a cells osmotic response to changes in temperature for 0°C and below for multiple cooling rates.


This is modelled as a change in the volume of the cell, which can then be interpreted by the chemical diffusion grid as water diffusing into the extracellular medium , in the case of cooling, and increase the concentration around the cell accordingly. The concentration grid will then diffuse the water throughout the remaining extracellular space at each time step of the simulation.


At current there is a Thermodynamics module being developed to accompany the behaviors for cellular behaviour and chemical diffusion, which will allow for further simulations to have a dynamic temperature field alongside the already existing dynamic chemical diffusion grid.

 Last December the 12th Physics World has delighted announced its Top 10 Breakthroughs of the Year for 2024, which includes research in nuclear and medical physics, quantum computing, lasers, antimatter and (of course ^_^) BioDynaMo . The Top Ten is the shortlist for the Physics World Breakthrough of the Year, which will be revealed on Thursday 19 December. PhysicsWorld editorial team has looked back at all the scientific discoveries reported on since 1 January and has picked 10 they judge are the most important. In addition to being reported in Physics World in 2024, the breakthroughs must meet the following criteria:  Significant advance in knowledge or understanding Importance of work for scientific progress and/or development of real-world applications Of general interest to Physics World readers  You can listen to the editors making their case for the research in the Top10 in this podcast What do they say about the BioDynaMo research they selected: <<Modelling...

Using BioDynaMo to Study Virus Spread in Closed Environments

 In addition to cellular studies (tumour growth modelling or neural development), BioDynaMo can be used to simulate different systems, such as groups of people and their interactions. As BioDynaMo has been developed to simulate billions of cells, it should be able to handle fairly easily simulations of up to millions of people. In one of these types of simulation, BioDynaMo is used to study the spreading of viruses in indoor spaces, specifically COVID-19 in droplets and aerosols. We are investigating several scenarios, such as public transportation (bus, metro) and buildings (supermarkets, offices). In these simulations BioDynaMo is in charge of simulating the behaviour and characteristics of individuals, while the ROOT geometrical modeller is used to define the precise environmental geometry. Each individual can then independently move around in these environments where infected individuals can possibly contaminate healthy ones through the spreading of droplets and aerosols. By st...

 Not long ago we had advertised a vacancy at CERN to join our collaboration -> link Despite receiving a great response, we failed to meet the right profile (all had great talents, but the acceptable experience accumulated after University degree is a hard requirement), and we are does readvertising the vacancy! Are you a Computer Scientist (or from a related field) and have obtained either: your Master's degree with 2 to 6 years of post-graduation professional experience; or your PhD with no more than 3 years of post-graduation professional experience? Would you say you honed excellent skills in the C++ programming language and have a keen interest in agent-based simulations solutions and computational biology? Are you a national of a CERN Member or Associate Member State? We are looking for you! Apply to join our team and gain experience in one of the most thriving and exciting laboratories in the world!!! https://jobs.smartrecruiters.com/CERN/743999964172854-agent-based-digita...
