Versatile Barometer Biosensor Based on Au@Pt Core/Shell Nanoparticle Probe

When it comes to testing for cancer, environmental pollution and food contaminants, traditional sensors can help. The challenges are that they often are bulky, expensive, non-intuitive and complicated. Now, one team reports in ACS Sensors that portable pressure-based detectors coupled with smartphone software could provide a simpler, more affordable alternative while still maintaining sensitivity.

Current disease and contamination sensors require expensive readout equipment or trained personnel. Yuehe Lin, Yong Tang and colleagues propose a new detection system based on pressure changes...

A Systematic Strategy for Discovering a Therapeutic Drug for Alzheimer’s Disease and Its Target Molecule. Frontiers in Pharmacology, 2017; 8 DOI: 10.3389/fphar.2017.00340

Japanese scientists have developed a method to isolate and identify active compounds in plant medicines, which accurately accounts for drug behavior in the body. Using the technique, they have identified several active compounds from Drynaria Rhizome, a traditional plant medicine, which improve memory and reduce disease characteristics in a mouse model of Alzheimer’s disease.

Traditional plant medicines have been used by humans for a long time, and these therapies are still popular in many countries...

A subpopulation of immune cells that normally fend off pathogens can turn against the host during certain infections, a new study publishing on June 20 in the open access journal PLOS Biology reveals. The researchers led by Dr...

A core assumption in the study of disease-causing genes has been that they are clustered in molecular pathways directly connected to the disease. But work by a group of researchers at the Stanford University School of Medicine suggests otherwise. The gene activity of cells is so broadly networked that virtually any gene can influence disease, the researchers found. As a result, most of the heritability of diseases is due not to a handful of core genes, but to tiny contributions from vast numbers of peripheral genes that function outside disease pathways.

Any given trait, it seems, is not controlled by a small set o...
