Growth and productivity in important crop plants is limited by the inefficiencies of the C3 photosynthetic pathway. Introducing CO2-concentrating mechanisms (CCMs) into C3 plants could overcome these limitations and lead to increased yields. Many unicellular microautotrophs, such as cyanobacteria and green algae, possess highly efficient biophysical CCMs that increase CO2 concentrations around the primary carboxylase enzyme, Rubisco, to enhance CO2 assimilation rates. Algal and cyanobacterial CCMs utilize distinct molecular components, but share several functional commonalities. Here we outline the recent progress and current challenges of engineering biophysical CCMs into C3 plants. We review the predicted requirements for a functional biophysical CCM based on current knowledge of cyanobacterial and algal CCMs, the molecular engineering tools and research pipelines required to translate our theoretical knowledge into practice, and the current challenges to achieving these goals.

Interleukin-12 (IL-12) is a robust proinflammatory cytokine that activates immune cells, such as T cells and natural killer cells, to induce antitumor immunity. However, the clinical application of recombinant IL-12 has been limited by systemic immune-related adverse events (irAEs) and rapid degradation. To address these challenges, we employed mRNA technology to encode a tumor-activated IL-12 "lock" fusion protein that offers both therapeutic efficacy and systemic safety.

Coherent electron spin states within paramagnetic molecules hold significant potential for microscopic quantum sensing. However, all-optical coherence measurements amenable to high spatial and temporal resolution under ambient conditions remain a significant challenge. Here we conduct room-temperature, picosecond time-resolved Faraday ellipticity/rotation (TRFE/R) measurements of the electron spin decoherence time in [IrBr].

When treatments are deemed not to be cost-effective and face non-reimbursement, policymakers in publicly funded healthcare systems may decide to ration treatments by withholding it from future patients. However, they must also address a critical question: should they also ration treatments by withdrawing it from patients already having access to the treatment, or is there an ethical difference between withdrawing and withholding treatments? To explore this question, we conducted a behavioural experiment (n=1404), examining public support for withdrawing and withholding treatments in reimbursement decisions across eleven different circumstances. Overall, public support for rationing by withdrawing and withholding was low, with no general perceived difference between withdrawing and withholding treatments.

Chimeric antigen receptor (CAR) therapies have demonstrated remarkable clinical efficacy in hematological malignancies, validating their therapeutic potential. However, challenges such as therapeutic resistance and limited accessibility hinder their broader application. To overcome these limitations, alternative CAR-based cell therapies, including CAR-Natural Killer (CAR-NK), CAR-macrophage (CAR-M), and CAR-dendritic cell (CAR-DC) therapies, have been proposed.

The increasing use of blood-contacting medical devices has brought about significant advancements in patient care, yet it also presents challenges such as thrombus formation and infection risks. Surface coatings play a vital role in mitigating these side effects, enhancing the safety and effectiveness of such devices. In this study, we introduced a novel coating employing poly(aspartic acid) (PASP), which can be easily applied through various modification pathways.
