Findings shed light on the evolution of human cognition, the capacity for long lifespan and the potential for neurodegenerative disease
A research team from the Salk Institute, the Yerkes National Primate Research Center of Emory University and the University of California – Los Angeles (UCLA), has identified genes in the cerebral cortex that differ in levels of activity between humans and nonhuman primates, including chimpanzees and rhesus monkeys. These findings, which appear in the online journal of the Proceedings of the National Academy of Sciences, may provide essential clues to the unusual cognitive abilities of humans. They also may help researchers understand why humans have a longer lifespan than other primate species and yet are so vulnerable to age-related, neurodegenerative diseases.
Because the DNA sequences of humans are so similar to those of chimpanzees, scientists have long speculated that differences in the activity levels of particular genes, otherwise known as gene expression, and, as a result, the amounts of particular proteins cells produce, are what distinguish humans from chimpanzees. The recent sequencing of the human genome has led to the development of "gene chips" that enable researches to examine the expression levels of thousands of genes at a time as well as compare expression levels in different species.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
