New 'law of biology' can predict patient-specific health events

Bioengineers from Rice University and physicians from Emory University are going to test whether a new "law of biology" can predict when a critically ill patient is about to worsen, and more importantly, which treatment is likely to prevent it.

Researchers identify facial characteristics of children with autism

The face and brain develop in coordination, with each influencing the other, beginning in the embryo and continuing through adolescence. Now, University of Missouri researchers have found distinct differences between the facial characteristics of children with autism compared to those of typically developing children.

Women with MET genetic variant and autoantibodies more likely to have autistic children

A study by researchers at UC Davis has found that pregnant women with a particular gene variation are more likely to produce autoantibodies to the brains of their developing fetuses and that the children of these mothers are at greater risk of later being diagnosed with autism.

Neuroscientists discover normal brain communication in people with AgCC

Like a bridge that spans a river to connect two major metropolises, the corpus callosum is the main conduit for information flowing between the left and right hemispheres of our brains. Now, neuroscientists at the California Institute of Technology have found that people who are born without that link-a condition called agenesis of the corpus callosum, or AgCC-still show remarkably normal communication across the gap between the two halves of their brains.

NIST, CU develop novel low-power transport microchip

Researchers from the National Institute of Standards and Technology (NIST) and University of Colorado Boulder (CU) have developed a low-power microchip that uses a combination of microfluidics and magnetic switches to trap and transport magnetic beads. The novel transport chip may have applications in biotechnology and medical diagnostics.

OPHN1 protein mediates mGluR-dependent longterm depression at synapses

Scientists at Cold Spring Harbor Laboratory (CSHL) have solved part of a puzzle concerning the relationship between changes in the strength of synapses - the tiny gaps across which nerve cells in the brain communicate - and dysfunctions in neural circuits that have been linked with drug addiction, mental retardation and other cognitive disorders.

Tenofovir gel shows promise against HSV infection

HIV infection is commonly associated with other sexual infections, such as herpes simplex virus (HSV). Infection with HSV facilitates the risk of HIV infection and negatively impacts the clinical course of HIV disease. Therefore, it would be highly beneficial to identify multi-faceted microbicide compounds that are efficient against HIV-1 and other sexually transmitted infections.
