Scientists have turned to the brightest brains in Britain in a bid to understand the link between intelligence and dementia.
A team of researchers from The University of Manchester will be asking members of the high-IQ society Mensa for DNA samples in what will be the world’s most sophisticated study of brainpower. The research will allow the team to find genes associated with intelligence and examine how they interact with each other. “When you look at the genes in combination you reduce the statistical power of the research considerably,” explained Dr Tony Payton, who works in the University’s Centre for Integrated Genomic Medical Research (CIGMR) and is leading the research. “Selecting individuals who represent the extreme end of the IQ distribution increases this power dramatically. For example, 200 volunteers with an IQ of 145 is equivalent to using 100,000 unselected volunteers.”
The results of the Mensa research will complement data collected from an earlier University of Manchester study of some 2,500 elderly people that has taken place over the last 20 years. That research has already uncovered two genes associated with general cognitive ability, while work elsewhere over the past eight years has identified a further 10 other ‘intelligence genes’. “The study of intelligence is shrouded by historical, biological, ethical and descriptive complexities that have made a mockery of its intended definition ‘to reason and understand’,” said Dr Payton. “Although our understanding of the biological basis of intelligence is still at an early stage, a general consensus about the role genes play in determining the level of intelligence has now been reached. “All of us possess the same genes but there are variations within the genes themselves, known as ‘polymorphisms’, which are largely responsible for what makes us all unique. “They have an important influence on factors such as our behaviour and susceptibility to disease and, of the genes implicated in intelligence, the associated polymorphism has been shown to alter the function of the gene.”

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
