New mathematical principle used to prevent AI from making unethical decisions
A new mathematical principle has been designed to combat AI bias towards making unethical and costly commercial choices. Researchers from the University of Warwick, Imperial College London, EPFL (Lausanne) and Sciteb Ltd have found a mathematical means of helping regulators and businesses manage artificial intelligence (AI) systems' biases towards making unethical, and potentially very costly and damaging, commercial choices.

Analysis: How the brain builds a sense of self from the people around us - new research
MBPhD researcher Sam Ereira (UCL Medical School) shares his research on brains and discusses how we distinguish between thinking about our minds versus those of others. We are highly sensitive to people around us. As infants, we observe our parents and teachers, and from them we learn how to walk, talk, read - and use smartphones.

Secularism and tolerance of minority groups predicts future prosperity of countries
Secularism and tolerance of minority groups predicts future prosperity of countries
Secular cultures which are tolerant of minority groups and respectful of individuals' rights tend to have more wealth, education and democracy, a new study by University of Bristol scientists has found. New research, which surveyed nearly half a million people across 109 countries, shows that changes in culture generally come before any improvements in wealth, education and democracy, rather than the other way around.

Opinion: School ability grouping is potentially harmful
In light of recent research findings, involving 9,000 pupils, that suggest attainment groupings may have an effect on pupils' self-confidence, Dr Becky Taylor (UCL Institute of Education) explains how schools may want to reflect on existing teaching practices. England's schools make more use of within-school "ability" grouping than those in other similar countries, yet there is no evidence that this practice results in better outcomes overall for students.

Numbers limit how accurately digital computers model chaos
Numbers limit how accurately digital computers model chaos
Digital computers use numbers based on flawed representations of real numbers, which may lead to inaccuracies when simulating the motion of molecules, weather systems and fluids, find UCL and Tufts University scientists. The study, published today in Advanced Theory and Simulations , shows that digital computers cannot reliably reproduce the behaviour of 'chaotic systems' which are widespread.

Thriving animal collectives like ants should move through their environment like ‘savvy gamblers’
Many animals have to move around in their environment to find resources to live and reproduce. Scientists have studied particular examples of this for many years but there are not many unifying frameworks to understand the general organising principles of animal movement. This is especially true for animal collectives like ant colonies, whose individual routes as they search for food can look rather like a ‘random walk'.

Common scents don’t always make the best perfumes, suggests mathematical study
Perfumes that use the most popular scents do not always obtain the highest number of ratings, according to an analysis of online perfume reviews. A study of 10,000 perfumes and their online ratings reveals which odours are likely to bring success, with some surprising combinations providing a boost to ratings.

New technique will help experts make heads or tails of male fertility
A new way of analysing sperm that tracks the movement of the sperm tail could enable substantial improvements to male fertility testing. The technique measures the speed and action of the sperm flagellum, or tail, which provides vital information for understanding whether sperm in an ejaculate have the potential to reach and fertilise the egg.

Opportunistic cancer cells ’slip through the gaps’ to spread through blood vessels
Cancer cells may rely on opportunism, as well as chemical signalling, to spread through the body, according to new findings by mathematicians at the University of Birmingham. Cancer spreads by sending cells out from the primary tumour to travel through the vascular or lymphatic system to colonise other organs in a process called metastasis.

Support for Conservative Party rises with UK house prices
Support for Conservative Party rises with UK house prices, new research reveals The big increase in housing wealth inequality in the UK over the period from 1995 to 2007 increased homeowners' probability of supporting the Conservative party. However, it did not make homeowners more averse to the state's ownership of public services.

Bristol mathematician cracks Diophantine puzzle
A mathematician from the University of Bristol has found a solution to part of a 64-year old mathematical problem - expressing the number 33 as the sum of three cubes. Since the 1950s, mathematicians have wondered if all whole numbers could be expressed as the sum of three cubes; whether the equation k = x³+ y³+ z³ always has a solution.

Half of London car crashes take place in 5% of the city’s junctions
The location of road accidents is not random and they tend to be highly concentrated in urban areas, according to a new UCL study. The study, published in the open-access journal Plos One , found that nearly 50% of the serious and fatal accidents in London take place in 5% of road junctions. † PhD candidate Rafael Prieto Curiel, lead researcher (UCL Mathematics), said: "Despite being a rare event, road accidents are among the top ten causes of death worldwide.
