Nanoparticles wiggling through mucus may predict severe COPD
In a proof-of-concept experiment, researchers say they have successfully used microscopic human-made particles to predict the severity of patients' chronic obstructive pulmonary disease (COPD) by measuring how quickly the particles move through mucus samples. The technique, say the researchers, could eventually help doctors deliver more effective treatments sooner.
Read moreUrban beaches are environmental hotspots for antibiotic resistance after rainfall
New research provide clear links between storm-water discharge, which sometimes includes wet-weather sewer overflow (WWSO) events, and the presence of AbR in microorganisms living in urban beach habitats.

Biologists have used bioelectronics to influence transpiration in a tobacco plant, without harming the plant in any way.
Read moreDitch the delicate wash cycle to help save our seas
The volume of water used during a wash cycle, rather than the spinning action of the washing machine, is the key factor in the release of plastic microfibres from clothes.
Read moreSimulations characterize turbulence caused by common connection for dialysis
The complex interplay among the arteriovenous grafts, the vessels they connect, and the blood they transport has been difficult to simulate, but one new method provides a way. Researchers report simulations that reconstructed the fluid dynamics affected by the insertion of an AVG. They used a model that considered the ability of AVG tubes and blood vessels to deform and found much of the disrupted flow could be mitigated by this flexibility.

Scientists have developed a new method of molecular design to control both temperature reversibility and stiffness of nanofibers that are gel-forming peptides. The peptide nanofiber hydrogel can be used as biomedical materials. This method will allow the peptide nanofibers more biomedical applicable.
Read moreGoing with the (slow) flow: New technique could improve biotech, precision medicine
Researchers have developed an optical system that accurately measures the flow of extraordinarily tiny amounts of liquids — as small as 10 billionths of a liter (nanoliters) per minute.
Read moreChemists clarify a chiral conundrum
Researchers set out to untangle the mysterious interactions in mixtures of proteins and gold nanorods. Their experiments revealed multilevel chirality in the way proteins prompt nanoparticles to align and in how the particles' plasmons respond to light in the proteins' presence.
