Researchers develop more reliable method for working with mathematical models
Researchers develop more reliable method for working with mathematical models
Scientists from Imperial College London have developed a way to make the conclusions drawn from mathematical models more reliable. The work has implications for fields as diverse as medical research and ecology. Models are, by necessity, gross simplifications and, as such, there is always the risk that the model - and so the conclusions we draw - are wrong Most scientists choose to work with one mathematical model and change the input parameters to see what different outcomes result.

Imperial mathematician sheds new light on 50 year old algorithm
Imperial mathematician sheds new light on 50 year old algorithm
An Imperial mathematician has found a new way of formulating a 50 year old algorithm, used when describing the world using mathematical models. It is anticipated that the proposed technique, published this week in the Proceedings of the National Academy of Sciences (PNAS), will pave the way for greatly accelerating the calculations involved when making predictions about the behaviour of complex systems in many different areas of science and engineering.

UCL professors use probabilities to persuade doubters skeleton is King Richard III
UCL professors use probabilities to persuade doubters skeleton is King Richard III
Two UCL professors led a key part of the new analysis of 'Skeleton 1'; which was discovered in a Leicester car park in 2012 on the site of the Grey Friars friary, the last known resting place of King Richard III. They used probability calculations to combine several different lines of evidence, producing an overall weight-of-evidence for the skeleton being that of King Richard III.

Study predicts likely Ebola cases entering UK and US through airport screening
The team examined the current growth rate of the epidemic in West Africa alongside airline travel patterns Researchers at the University of Liverpool have found that screening for Ebola at airports could be an effective method for preventing the spread of the disease into the UK and US, but due to the long incubation period of the virus, screening won't detect all cases Published in the Lancet medical journal, the study used a mathematical model to test the probability of infected travellers from West Africa entering the UK and US.

Equation to predict happiness
Equation to predict happiness
The happiness of over 18,000 people worldwide has been predicted by a mathematical equation developed by researchers at UCL, with results showing that moment-to-moment happiness reflects not just how well things are going, but whether things are going better than expected. The new equation accurately predicts exactly how happy people will say they are from moment to moment based on recent events, such as the rewards they receive and the expectations they have during a decision-making task.

Mathematical model illustrates our online 'copycat' behaviour
Researchers have developed a mathematical model to examine online social networks, in particular the trade-off between copying what friends download and relying on 'best-seller' lists. The researchers from the University of Oxford, the University of Limerick, and the Harvard School of Public Health looked at how we are influenced in the choice of apps we download on our Facebook pages by creating a mathematical model to capture the dynamics at play.

Equations reveal the rebellious rhythms at the heart of nature
Equations reveal the rebellious rhythms at the heart of nature
Physicists are using equations to reveal the hidden complexities of the human body. From the beating of our hearts to the proper functioning of our brains, many systems in nature depend on collections of 'oscillators'; perfectly-coordinated, rhythmic systems working together in flux, like the cardiac muscle cells in the heart.

Sperm against the stream
Research may explain how sperm travel long distances, through difficult terrain, to reach an egg. Our findings highlight the very subtle interplay between the geometry of the sperm cells and their response to fluid flow near the chamber walls Raymond Goldstein Like salmon travelling upstream to spawn, sperm cells are extremely efficient at swimming against the current.

Statistical analysis unveils the hidden patterns in Eurovision voting
Statistical analysis unveils the hidden patterns in Eurovision voting
Voting for the Eurovision Song Contest has been scrutinised by statistics experts at UCL and Imperial College London, who have found that musical talent is unlikely to be the only element that wins scores - but that the contest is not 'stitched up' at the UK's expense. The analysis of voting patterns over the past two decades suggests that widespread support for certain countries' acts is, however, not driven by prejudice, as the media periodically suggests, but by positive loyalties based on culture, geography, history and migration.

Scientists unmask the climate uncertainty monster
Press release issued: 4 April 2014 Increasing uncertainty in the climate system compels a greater urgency for climate change mitigation, according to new research from the University of Bristol. Scientific uncertainty has been described as a 'monster' that prevents understanding and delays mitigative action in response to climate change.

Future of cyber security is in the mind
The research draws on psychological studies and uses mathematical models to improve how decisions are made when dealing with complex security IT problems The University of Liverpool is developing a new tool that can protect organisations of all sizes from cyber threats. Cyber security is recognised as a serious challenge to economic and national security and it is estimated to cost the UK economy 10billion a year.

Negative feedback makes cells ’sensitive’
New research has shown that negative feedback loops in cell signalling systems can be essential for a cell's ability to perceive the strength of a growth stimulus. Cells lacking the feedback loop became insensitive to the level of the stimulus in a manner similar to a cancerous cell displaying unrestrained growth.
