Autism begins in pregnancy, according to study: Cortical layers disrupted during brain development in autism

Autism begins in pregnancy, according to study: Cortical layers disrupted during brain development in autism

Researchers at the University of California, San Diego School of Medicine and the Allen Institute for Brain Science have published a study that gives clear and direct new evidence that autism begins during pregnancy. The study will be published in the March 27 online edition of the New England Journal of Medicine . The researchers — Eric Courchesne, PhD, professor of neurosciences and director of the Autism Center of Excellence at UC San Diego, Ed S. Continue reading

New clue to autism found inside brain cells

New clue to autism found inside brain cells

The problems people with autism have with memory formation, higher-level thinking and social interactions may be partially attributable to the activity of receptors inside brain cells, researchers at Washington University School of Medicine in St. Louis have learned Continue reading

Pathogens in cheese: Case study on Austrian curd cheese

Pathogens in cheese: Case study on Austrian curd cheese

If food products are not produced in a hygienic environment, consumers can face the threat of dangerous pathogens. This is exactly what happened in 2009 and 2010 when two different strains of Listeria monocytogenes were found in the traditional Austrian curd cheese known as “Quargel.” 34 people were infected, and a total of 8 patients died.

New regulatory mechanisms of cell migration found in drosphilia fly study

New regulatory mechanisms of cell migration found in drosphilia fly study

A study by Sofia J. Araújo, a Ramón y Cajal researcher with the Morphogenesis in Drosophila lab at the Institute for Research in Biomedicine (IRB), elucidates the genetic regulation of cell migration. Published today in the scientific journal Plos One , the research is part of the thesis work performed by Elisenda Butí, first author of the article Continue reading

Proteins that control energy use necessary to form stem cells

Proteins that control energy use necessary to form stem cells

Two proteins that control how cells break down glucose play a key role in forming human stem cells, University of Washington researchers have found. The finding has implications for future work in both regenerative medicine and cancer therapy Continue reading

Advance toward developing an oral pain reliever derived from debilitating snail venom

Scientists have reported they have created at least five new experimental substances — based on a tiny protein found in cone snail venom — that could someday lead to the development of safe and effective oral medications for treatment of chronic nerve pain. Continue reading

Tension triggers muscle building

Tension triggers muscle building

Skeletal muscles are built from small contractile units, the sarcomeres. Many of these sarcomeres are connected in a well-ordered series to form myofibrils that span from one muscle end to the other. Continue reading

‘Fluorescent’ mouse can teach us about many diseases, drugs

‘Fluorescent’ mouse can teach us about many diseases, drugs

Scientists from the UK and Australia have created a mouse that expresses a fluorescing ‘biosensor’ in every cell of its body, allowing diseased cells and drugs to be tracked and evaluated in real time and in three dimensions. This biosensor mimics the action of a target molecule, in this case a protein known as ‘Rac’, which drives cell movement in many types of cancer. Rac behaves like a switch, oscillating on the molecular level between two states — active or inactive Continue reading
