Despite many innovations, meeting both economic and ecological requirements remains challenging for conventional resource recovery technology. The development of highly selective peptides puts a new competitor on the market. We present an approach to identify peptides for resource recovery using Phage Surface Display. Here, we describe the development of peptides for binding of rare earth element terbium-containing solids and for removal and enrichment of the heavy metal ions of cobalt and nickel out of waste waters and leaching solutions. We identified phage displaying specific peptides with ∼100× enhanced affinity towards terbium-containing solids or ∼20× enhanced affinity towards nickel (∼3× cobalt).

Fluorinated gases (F-gases) play a vital role in the chemical industry and in the fields of air conditioning, refrigeration, health care, and organic synthesis. However, the direct emission of waste gases containing F-gases into the atmosphere contributes to greenhouse effects and generates toxic substances. Developing porous materials for the energy-efficient capture, separation, and recovery of F-gases is highly desired.

Freshwater ecosystems face significant threats, including pollution, habitat loss, invasive species, and climate change. To address these challenges, management strategies and restoration efforts have been broadly implemented. Across Europe, such efforts have resulted in overall improvements in freshwater biodiversity, but recovery has stalled or failed to occur in many localities, which may be partly caused by the limited dispersal capacity of many species.

Cold stress (CS) is a significant natural hazard, and distinguishing between plant cold resistance and sensitivity is critical for cultivar breeding and the development of germplasm resources. This study used 205 tobacco (Nicotiana tabacum L.) varieties from around the world to investigate the changes in the chlorophyll a fluorescence (OJIP) transients, JIP-test parameters, and seedling growth caused by seven days of CS (5°C) treatment.

Mental illness, affecting one in eight people worldwide, is often exacerbated by stigma-which can result in self-stigmatization, isolation, and loneliness and negatively impact access to health care, education, and social connection. Previous research has found that stigma is best reduced through a combination of education about the stigmatized population and intentional contact with individuals from that population. Studies also note the benefits of community-based, culturally-relevant interventions and cultural experiences such as live music.

Timely and accurate detection of trace mycotoxins in agricultural products and food is significant for ensuring food safety and public health. Herein, a deep learning-assisted and entropy-driven catalysis (EDC)-Argonaute powered fluorescence single-particle aptasensing platform was developed for ultrasensitive detection of fumonisin B (FB) using single-stranded DNA modified with biotin and red fluorescence-encoded microspheres as a signal probe and streptavidin-conjugated magnetic beads as separation carriers. The binding of aptamer with FB releases the trigger sequence to mediate EDC cycle to produce numerous 5'-phosphorylated output sequences, which can be used as the guide DNA to activate downstream Argonaute (Ago) for cleaving the signal probe, resulting in increased number of fluorescence microspheres remaining in the final reaction supernatant after magnetic separation.
