Hair follicle models from the 3D printer      (via sciencedaily.com)     Original source 

Hair follicle infections are often difficult to treat because bacteria settle in the gap between hair and skin, where it is difficult for active substances to reach them. In order to investigate this scenario more closely in the laboratory, researchers have now developed a model with human hair follicles embedded in a matrix produced using 3D printing. In the future, this model can be used to test the effectiveness of new drug candidates against corresponding pathogens directly on human follicles.

Plant-inspired polymers for water purification      (via sciencedaily.com)     Original source 

Researchers have synthesized a bio-inspired polymer for water purification. The polymer was designed to mimic phytochelatin, a plant protein that selectively captures and neutralizes harmful heavy metal ions. The hyperconfinement of the polymer enabled a flow-through system and effectively removed cadmium ions from contaminated water, making it safe to drink. The system was selective for heavy metals and provides a new way to remove specific contaminants from water.

New additive process can make better -- and greener -- high-value chemicals      (via sciencedaily.com)     Original source 

Researchers have achieved a significant breakthrough that could lead to better -- and greener -- agricultural chemicals and everyday products. Using a process that combines natural enzymes and light, the team developed an eco-friendly way to precisely mix fluorine, an important additive, into chemicals called olefins -- hydrocarbons used in a vast array of products, from detergents to fuels to medicines. This groundbreaking method offers an efficient new strategy for creating high-value chemicals with potential applications in agrochemicals, pharmaceuticals, renewable fuels, and more.

New understanding of fly behavior has potential application in robotics, public safety      (via sciencedaily.com)     Original source 

Scientists have identified an automatic behavior in flies that helps them assess wind conditions -- its presence and direction -- before deploying a strategy to follow a scent to its source. The fact that they can do this is surprising -- can you tell if there's a gentle breeze if you stick your head out of a moving car? Flies aren't just reacting to an odor with a preprogrammed response: they are responding in context-appropriate manner. This knowledge potentially could be applied to train more sophisticated algorithms for scent-detecting drones to find the source of chemical leaks.

Researchers explore the interplay between high-affinity DNA and carbon nanotubes      (via sciencedaily.com)     Original source 

Single-walled carbon nanotubes (SWCNTs) hold promise for biomedicine and nanoelectronics, yet the functionalization with single-stranded DNA (ssDNA) remains a challenge. Researchers using high-affinity ssDNA sequences identified through high-throughput selection. They demonstrated the effectivity and stability of these constructs using molecular dynamics simulations. Machine-learning models were used to accurately predict patterns that govern ssDNA-SWCNT binding affinity. These findings provide valuable insights into the interactions between ssDNA and SWCNTs.
