Research co-authored by Queen Mary University of London (QMUL) has found that the 'maths gender gap' - the relative underperformance of girls at maths - is much wider in societies with poor rates of gender equality. Published today in the American Economic Review, the research shows that the performance gap between girls and boys is far less pronounced in societies that hold progressive and egalitarian views about the role of women.

Using data from the world’s most powerful X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory, an international team of scientists has made a crucial advance in analyzing ultrafast motions of molecules. They developed a computational method that increases the accuracy of this analysis 300 times – to one femtosecond, which is a millionth of a billionth of a second.

In 1655 the English mathematician John Wallis published a book in which he derived a formula for pi as the product of an infinite series of ratios. Now researchers from the University of Rochester, in a surprise discovery, have found the same formula in quantum mechanical calculations of the energy levels of a hydrogen atom. The researchers report their findings in the Journal of Mathematical Physics.

An emerging technique called fluctuation X-ray scattering (FXS) could provide much more detail about a protein’s molecular structure than traditional solution scattering. But a major limitation for FXS has been a lack of math methods to efficiently interpret the data. That’s where Berkeley Lab’s M-TIP comes in.
