Direct air capture (DAC) is an emerging technology aimed at mitigating global warming. However, conventional DAC technologies and the subsequent utilization processes are complex and energy-intensive. An integrated system of direct air capture and utilization (IDACU) via in-situ catalytic conversion to fuels and chemicals is a promising approach, although it remains in the early stages of development. This review examines the current technical routes of IDACU, including solid-based dual-functional materials (DFMs) through thermo-catalysis, IDACU using liquid sorbents with thermo-catalysis, and non-thermal conversion methods. It covers the basic principles, reaction conditions, main products, material types, and the existing problems and challenges associated with these technical routes. Additionally, it discusses the recent advancements in solid-based DFMs for IDACU, with particular attention to the differences in material characteristics between carbon capture from flue gases (ICCU) and DAC. While IDACU technology holds significant promise, it still faces numerous challenges, especially in the design of advanced materials.

In a recent study published in Science China Earth Sciences, a team of researchers proposed using an orthogonal conditional nonlinear optimal perturbations (O-CNOPs) method to tackle the challenge of forecasting unusual tropical cyclone (TC) tracks. Their findings revealed that this method exhibits exceptional capability in generating ensemble members that accurately predict sharp TC turns. The O-CNOPs method holds potential as a transformative tool for addressing the forecasting challenge, offering a more precise and reliable solution for predicting TC behavior.

Forecasting unusual TC tracks has long been a persistent challenge in TC prediction, with limited progress made over the years. However, this study demonstrated that the O-CNOPs outperformed traditional methods [singular vectors (SVs) and bred vectors (BVs)] by providing more stable and reliable improvements in TC track forecasting skills. Notably, at lead times of one to five days, the O-CNOPs showed superior ability to generate ensemble members that accurately predict sharp TC turns. Thus, the study offers a new ensemble forecasting technology to enhance the accuracy of unusual TC track forecasts, with potential for becoming a valuable approach to address this forecasting challenge.

Cleaning blood from a violent crime scene can complicate crime scene investigations, particularly when accurate evidence is required for a conviction in court.

A new study led by Flinders University forensic science compares evidence collected from remaining DNA and haemoglobin (red blood cells) left on cotton t-shirt material and metal knives from wet and dried blood cleaned  with a variety of different common cleaning products. 

A review article entitled "Scaffold-Mediated Microenvironmental Modulation Targeting Osteoclasts for ONFH Niche Reprogramming" has been published in Research. This article systematically summarizes the latest progress in functionalized bioactive scaffolds for regulating the intraosseous microenvironment in the treatment of early osteonecrosis of the femoral head (ONFH). Innovatively, from the perspective of osteoclast heterogeneity, it proposes a novel concept of "osteoclast-centric reprogramming of the osteonecrotic microenvironment," providing a new theoretical framework and design direction for the material-based treatment of ONFH.

SAN ANTONIO — February 23, 2026 — Southwest Research Institute was part of an international team that demonstrated how complex organic molecules (COMs), key chemical precursors to life, could have been incorporated into Jupiter’s Galilean moons during their formation. The team’s findings have resulted in complementary studies published in The Planetary Science Journal and Monthly Notices of the Royal Astronomical Society, offering new insights into the potential for life in the Jovian system.

A simple palladium-catalyzed reaction system of C₂H₆-O₂-CO-H₂O that enables the selective oxidation of ethane to acetate acid, has been reported in a recent paper published in National Science Review. In the refined reaction system with the addition of sulfuric acid, it achieves remarkable performance with high ethane conversion of 15.7% and high acetate acid selectivity of 92.1%. The reaction pathway and mechanism are clearly interpreted through kinetic and spectroscopic analyses and supported by theoretical calculations. This study offers a promising pathway for the upgrading and utilization of natural gas under mild conditions.
