Nanosensor Arrays 'Smell' Cancer

(PhysOrg.com) -- In 2006 researchers established that dogs could detect cancer by sniffing the exhaled breath of cancer patients. Now, using nanoscale arrays of detectors, two groups of investigators have shown that a compact ...

Bacterial colonization of the lung also depends on the host genome

The lung is by no means a sterile place, as was assumed for a long time. In fact, it actually harbors a diverse microbial ecosystem. We know from previous studies that changes in the lung microbiome are associated with diseases ...

How cells zip through the stickiest mucus

A team led by Johns Hopkins University engineers figured out how and why human cells move much faster through thick mucus than thinner varieties. People sick with certain diseases, including asthma and COVID-19, secrete mucus ...

Smoke from wildfires ages in the atmosphere

Emissions, like smoke from wildfires and exhaust from vehicles, go through chemical changes when they enter the atmosphere. New research from the University of Georgia shows, for the first time, that these changes may affect ...

New bioink brings 3D-printing of human organs closer to reality

Researchers at Lund University have designed a new bioink which allows small human-sized airways to be 3D-bioprinted with the help of patient cells for the first time. The 3D-printed constructs are biocompatible and support ...

This US wildfire season is among the worst: Here's why

Acrid yellow smoke clogs the skies of major Western U.S. cities, a human-caused fire in the Columbia River Gorge rains ash on Portland, Oregon, and a century-old backcountry chalet burns to the ground in Montana's Glacier ...

Nanoparticle exposure can awaken dormant viruses in the lungs

Nanoparticles from combustion engines can activate viruses that are dormant in in lung tissue cells. This is the result of a study by researchers of Helmholtz Zentrum München, a partner in the German Center for Lung Research ...

Tailored 'activity coaching' by smartphone

Today's smartphone user can obtain a lot of data about his or her health, thanks to built-in or separate sensors. Researcher Harm op den Akker of the University of Twente (CTIT Institute) now takes this health monitoring ...
