New material in the fight against hospital-acquired infections


Researchers at the Universitat Jaume I (UJI) in Castellón, Spain, have developed a new light-activated antimicrobial material for use in the fight against the most common hospital infections. Led by professor Francisco Galindo and researcher Alicia Beltrán, the results have been published in the Journal of Materials Chemistry.

Wearable sensors can tell when you are getting sick


Wearable sensors that monitor heart rate, activity, skin temperature and other variables can reveal a lot about what is going on inside a person, including the onset of infection, inflammation and even insulin resistance, according to a study by researchers at the Stanford University School of Medicine.

Deciphering the beetle exoskeleton with nanomechanics


What can a beetle tell us about good design principles? Quite a lot, actually. Many insects and crustaceans possess hard, armor-like exoskeletons that, in theory, should weigh the creatures down. But, instead, the exoskeletons are surprisingly light. Northwestern Engineering's Horacio D. Espinosa and his group are working to understand the underlying design principles and mechanical properties.

Study finds postdoc jobs in biomedicine don't yield positive returns in the labor market


A new study by Boston University Questrom School of Business and University of Kansas researchers has found that postdoc jobs don't yield a positive return in the labor market, and that these positions likely cost graduates roughly three years' worth of salary in their first 15 years of their careers.

Chance meeting leads to creation of antibiotic spider silk


An interdisciplinary team of scientists at The University of Nottingham has developed a technique to produce chemically functionalized spider silk that can be tailored to applications used in drug delivery, regenerative medicine and wound healing.

Manufacturing platform makes intricate biocompatible micromachines


A team of researchers led by Biomedical Engineering Professor Sam Sia has developed a way to manufacture microscale-sized machines from biomaterials that can safely be implanted in the body. Working with hydrogels, which are biocompatible materials that engineers have been studying for decades, Sia has invented a new technique.

A closer look at the eye


Researchers have developed a new imaging technique that could revolutionize how eye health and disease are assessed. The group is first to be able to make out individual cells at the back of the eye that are implicated in vision loss in diseases like glaucoma. They hope their new technique could prevent vision loss via earlier diagnosis and treatment for these diseases.

Nanohyperthermia softens tumors to improve treatment


The mechanical resistance of tumors and collateral damage of standard treatments often hinder efforts to defeat cancers. However, a team of researchers from the CNRS, the French National Institute of Health and Medical Research (INSERM), Paris Descartes University, and Paris Diderot University has successfully softened malignant tumors by heating them.

Magnetic stimulation: more precise, reliable activation of neural circuitry


Massachusetts General Hospital (MGH) researchers have developed what appears to be a significant improvement in the technology behind brain implants used to activate neural circuits responsible for vision, hearing or movement.
