Students returning home may have caused 9,400 secondary COVID-19 infections across UK

A student infected with COVID-19 returning home from university for Christmas would, on average, have infected just less than one other household member with the virus, according to a new model devised by mathematicians at Cardiff University and published in Health Systems. Professor Paul Harper and colleagues defined an equation to predict the number of […]

Simulating evolution to understand a hidden switch

IMAGE: Using computer simulations built on reasonable assumptions and conducted under careful control, computational bioscientists can mimic real biological conditions. Starting with the original founding population (ancient phase), they can evolve… view more  Credit: © 2021 KAUST; Anastasia Serin Computer simulations of cells evolving over tens of thousands of generations reveal why some organisms retain a […]

A new tool to facilitate quicker, error-free software design

Any building project requires the formulation of a series of initial plans prior to starting construction to serve as a basis and guide for the whole process. A similar procedure is followed in software development, with the inclusion of a specific step known as modelling. “The process is equivalent to the production of a set […]

New treatment allows some people with spinal cord injury to regain hand and arm function

Almost 18,000 Americans experience traumatic spinal cord injuries every year. Many of these people are unable to use their hands and arms and can’t do everyday tasks such as eating, grooming or drinking water without help. Using physical therapy combined with a noninvasive method of stimulating nerve cells in the spinal cord, University of Washington […]
