Defective Gene Linked to Two Inherited Immune Deficiencies

...is likely that as yet unidentified genetic defects underlie CVID and IgA deficiency in those cases where TACI was not mutated. When the scientists further examined four of the five individuals with TACI mutations, they found all four had relatives with the same mutations. Eleven of the 12 identified relative...

What Makes The Brain Tick, Tick, Tick: Researchers Gaining New Insights Into Brain's Internal Clock

...enges. One is to find the molecular processes that underlie this internal clock. And the second challenge is to build more realistic models of how this timing process works, with constant, parallel input from throughout the brain." In such studies, the researchers face the daunting process of trying to monito...

Complex gene interactions account for autism risk

...derstanding of the complexity of interactions that underlie autism," Pericak-Vance said. "We can now apply the analytical approach to other genes that may play a role in the disease." Such findings may ultimately yield a method to screen for individuals at high risk for the disease, she added. "The new findi...

Plant genes identified that can form basis for crops better adapted to environmental conditions

...optimal control. Although the precise factors that underlie these processes and how they work together are virtually unknown, it has been quite clear that an enormous number of factors are involved. Tom Beeckman and his team in the VIB Department of Plant Systems Biology took on the challenge of identifying...

Center releases new public survey on stem cells

... ESC research to explore the competing values that underlie them. Survey respondents were asked a series of questions designed to ascertain the value placed on progress in ESC research and protecting early human embryos. The survey revealed a subtle topography of the public's attitudes with only a small fra...

Bigger brain size matters for intellectual ability

... or structure of the localized brain regions which underlie spatial skills in men is related to spatial intelligence, as was shown in previous research in Witelson's lab on the brain of Albert Einstein. In a further sex difference, brain size decreased with age in men over the age span of 25 to 80 years, but...

By revealing the capacity of mRNA splicing in dendrites, the investigators hope to develop an understanding of its role in cognition and dysfunction.

"We could not have reached these conclusions by independently studying the genome sequence of each individual pathogen," he adds. "...

Tiny RNA molecules fine-tune the brain's synapses

One of the key steps in the evolution of social insects, therefore, may have been the development of a mechanism for making centrosomes from scratch.
