Late last week the French National Centre for Scientific Research (CNRS - the acronym is based on the French translation) put out a press release describing a study conducted through a collaboration between several of its researchers and scientists from The University of Strasbourg. CNRS is a large (30,000+ employees), government-run research institution in France. It is the largest research organization in Europe, and is responsible for about 1/2 of the French scientific papers published annual........ Read more »

The endoplasmic reticulum and humans have quite a bit in common. Both are dynamic and constantly changing, but both also need something to ground and stabilize them. Maybe I’m reading too much into the beauty of the ER, but the image today is from a paper that only fuels my fascination. The endoplasmic reticulum (ER) is a large, complex membrane-bound organelle that spreads throughout the cell and hosts the synthesis, folding, and sorting of membrane and secretory proteins. This network is ........ Read more »

I became disenchanted with the idea of e-books when Amazon reached into scores of Kindles and removed copies of (of all possible books) 1984 and Animal Farm. The notion that a major company had the power to deny access to any content they deemed problematic simply presented too many visions of reactive, totalitarian control.
I never considered that those very concerns might apply to the publishers of scientific research, who – in this age of online-only publications – have the pow........ Read more »

The paper by Suzanne Goh and colleagues  reporting on "a possible neurobiological subtype of mitochondrial dysfunction in ASD [autism spectrum disorder]" is a worthy addition to the research roll call which has graced this blog down the years. Based on the analysis of brain lactate levels - a potential marker of mitochondrial dysfunction - via the analysis of lactate doublets on brain magnetic resonance spectroscopic imaging (MRSI), authors picked up a significantly higher rate of l........
