Comparison of Adulthood Outcomes in Autism Spectrum Disorder With and Without Regression: A Population‐Based Birth Cohort Study

Autism Research, EarlyView.
ABSTRACT The long‐term outcomes of regression in autism spectrum disorder (ASD) remain unclear. Previous evidence suggests that autistic individuals with regression have poorer adulthood outcomes across various indices than those without regression. We compared two groups—those with and without regression in ASD—among 168 participants from a population‐

A novel treatment of biogas digestate waste for biochar production and its adsorption of methylene blue and malachite green in a binary system

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study presents a novel treatment of biogas digestate to produce biochar at processing temperatures of 500–700 °C. The resulting biochar was applied for the simultaneous removal of methylene blue (MB) and malachite green (MG) in a binary system.

Neck‐vein thrombosis during spaceflight

British Journal of Clinical Pharmacology, EarlyView.
Spaceflight imposes unique environmental challenges, including weightlessness, increased radiation exposure and confinement, which can lead to unexpected health effects. One such example is neck‐vein thrombosis, a condition rarely seen on Earth without predisposing factors such as venous catheters or infections.
