Scientists at UCL (University College London) have discovered the area of the brain linked to dyscalculia, a maths learning disability. The finding shows that there is a separate part of the brain used for counting that is essential for diagnosis and an understanding of why many people struggle with maths.
The paper, published online today in the Proceedings of the National Academy of Sciences (PNAS), explains that an area of the brain widely thought to be involved in processing number information generally, in fact has two very separate, specific functions. One function is responsible for counting ‘how many’ things are present and the other is responsible for knowing ‘how much’.
It is the discovery of the part responsible for counting or numerosity that is a major finding for Professor Brian Butterworth, who also published ‘The Mathematical Brain’ and is an authority on dyscalculia. He believes his finding is the key to diagnosis of dyscalculia.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
