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.

Traffic-related ultrafine particles hinder mitochondrial functions in olfactory mucosa      (via sciencedaily.com)     Original source 

Ultrafine particles, UFPs, the smallest contributors to air pollution, hinder the function of mitochondria in human olfactory mucosa cells, a new study shows. The study showed that traffic-related UFPs impair mitochondrial functions in primary human olfactory mucosa cells by hampering oxidative phosphorylation and redox balance.

Researchers clarify how soft materials fail under stress      (via sciencedaily.com)     Original source 

Understanding how soft materials fail under stress is critical for solving engineering challenges as disparate as pharmaceutical technology and landslide prevention. A new study linking a spectrum of soft material behaviors -- previously thought to be unrelated -- led researchers to identify a new parameter they call the brittility factor, which allows them to simplify soft material failure behavior. This will ultimately help engineers design better materials that meet future challenges.

Converting wastewater to fertilizer with fungal treatment      (via sciencedaily.com)     Original source 

Creating fertilizers from organic waste can help reduce the consumption of fossil fuels and promote sustainable production. One way of doing this is through hydrothermal liquefaction (HTL), which converts biomass into biocrude oil through a high-temperature, high-pressure process. Two studies explore the use of a fungal treatment to convert the leftover wastewater into fertilizer for agricultural crops.
