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.

Preschool-age children are most engaged in pretend play 10-15 minutes after playing begins. In addition, girls exhibit higher organisational skills, according to a study conducted by researchers from SWPS University and Istanbul University-Cerrahpaşa.
