The avoidance of financial gain in the human body is an international ethical standard that underpins efforts to promote equity in donation and transplantation and to avoid the exploitation of vulnerable populations. The avoidance of financial loss due to donation of organs, tissues, and cells is also now recognized as an ethical imperative that fosters equity in donation and transplantation and supports the well-being of donors and their families. Nevertheless, there has been little progress in achieving financial neutrality in donations in most countries. We present here the findings of an international ethics working group convened in preparation for the 2023 Global Summit on Convergence in Transplantation, held in Santander, Spain, which was tasked with formulating recommendations for action to promote financial neutrality in donation. In particular, we discuss the potential difficulty of distinguishing interventions that address donation-related costs from those that may act as a financial incentive for donation, which may inhibit efforts to cover costs. We also outline some practical strategies to assist governments in designing, implementing, and evaluating policies and programs to support progress toward financial neutrality in donation.

The response to climate change and air pollution control demonstrates strong synergy across scientific mechanisms, targets, strategies, and governance systems. This report, based on a monitoring indicator system for coordinated governance of air pollution and climate change, employs an interdisciplinary approach combining natural and social sciences. It establishes 20 indicators across five key areas: air pollution and climate change, governance systems and practices, structural transformation and technologies, atmospheric components and emission reduction pathways, and health impacts and co-benefits.

Hot dry rock (HDR) geothermal is a sustainable and clean energy source. However, its development progress is hindered by creating seepage channels in deep reservoirs with low porosity and permeability. Traditional hydraulic fracturing techniques are ineffective for enhancing the permeability of these high-strength reservoirs.

Transparent conducting oxides (TCOs) are widely used in modern electronics because they have both high transmittance and good conductivity, which is beneficial for many applications such as light-emitting diodes. Tailoring electronic states and hence the conductive types by design is important for developing new materials with optimal properties for TCOs. SnO, with a wide band gap, low cost, no toxins, and high stability, is a promising host material for TCOs.

The ecological risk of microplastics (MPs) has received widespread attention, but understanding ecological risk starts with understanding environmental migration. Heteroaggregation is an important process that affects the vertical migration of MPs, and the mathematical model is a common tool used to project the migration behavior of MPs. However, the mathematical model based on the aggregation of MPs with one clay particle is not applicable to simulate the migration behavior of buoyant microplastic (BMP).

Despite the ultrahigh theoretical energy density and cost-effectiveness, aprotic lithium-oxygen (Li-O) batteries suffer from slow oxygen redox kinetics at cathodes and large voltage hysteresis. Here, we well-design ultrafine Co nanoparticles supported by N-doped mesoporous hollow carbon nanospindles (Co@HCNs) to serve as efficient electrocatalysts for Li-O battery. Benefiting from strong metal-support interactions, the obtained Co@HCNs manifest high affinity for the LiO intermediate, promoting formation of ultrathin nanosheet-like LiO with low-impedance contact interface on the Co@HCNs cathode surface, which facilitates the reversible decomposition upon charging.
