First study to model the organisation behind trade in illegal border crossings shows no “Mafia-like” monopoly of routes from Africa into Europe via Mediterranean. Instead, myriad independent smugglers compete in open markets that have emerged at every stage of the journey.
An innovative new study takes a network theory approach to targeted treatment in rural Africa, and finds that a simple algorithm may be more effective than current policies, as well as easier to deploy, when it comes to preventing disease spread – by finding those with “most connections to sick people”.
An online experiment reveals that the overall level of cooperation in a group almost doubles when the previous actions of all its members are rendered transparent. When all social connections within the group are also made transparent, the most cooperative band together to form their own community – ostracizing the less cooperative.
Private information would be much more secure if individuals moved away from cloud-based storage towards peer-to-peer systems, where data is stored in a variety of ways and across a variety of sites, argues a University of Cambridge researcher.
Most of the moves we make are within 5 km of our previous addresses, yet these short migrations are highly significant within individual lives. New research is looking at the links between residential mobility, life events and exchanges of social support within families.
Threats that cause supply chains and other networks to break down can cascade through today’s interconnected world of social, economic and financial interaction. New research is redefining this global risk to help businesses and governments build resilience.
Understanding the spread of infectious diseases in populations is the key to controlling them. If the UK was facing a flu pandemic, how could we measure where the greatest spreading risk comes from? This information could help inform decisions on whether to impose travel restrictions or close schools.
A new project has shown that by using existing sources of information about traffic flow it is possible to create a minute-by-minute image of congestion in cities.
