New UK study reveals extent of brain complications in children hospitalized with COVID-19
(University of Liverpool) Although the risk of a child being admitted to hospital due to COVID-19 is small, a new UK study has found that around 1 in 20 of children hospitalised with COVID-19 develop brain or nerve complications linked to the viral infection.

From genes to memes: Algorithm may help scientists demystify complex networks
(Penn State) A team of researchers has developed a new algorithm that can serve as a more effective way to analyze models of biological systems, which in turn allows a new path to understanding the decision-making circuits that make up these systems. The researchers add that the algorithm will help scientists study how relatively simple actions lead to complex behaviors, such as cancer growth and voting patterns.

When mad AIOLOS drags IKAROS down: A novel pathogenic mechanism
(Tokyo Medical and Dental University) Researchers from TMDU have described a novel primary immunodeficiency due to a mutation in AIOLOS. This acts through a novel pathogenic mechanism termed " heterodimeric interference " , whereby when two different proteins bind together in a heterodimer, the mutant protein hijacks the function of the normal protein. In a mouse model, they were able to restore some of the lost functions by interfering with the mutated protein, suggesting a possible therapeutic approach to disorders of this nature.

Autism can be detected during toddlerhood using a brief questionnaire
(University of Cambridge) New research led by the University of Cambridge suggests that autism can be detected at 18-30 months using the Quantitative Checklist for Autism in Toddlers (Q-CHAT), but it is not possible to identify every child at a young age who will later be diagnosed as autistic. The results are published today in The BMJ Paediatrics Open. (Source: EurekAlert! - Medicine and Health)

NIH-funded study finds gene therapy may restore missing enzyme in rare disease
(NIH/National Institute of Neurological Disorders and Stroke) A new study published in Nature Communications suggests that gene therapy delivered into the brain may be safe and effective in treating aromatic L-amino acid decarboxylase (AADC) deficiency. AADC deficiency is a rare neurological disorder that develops in infancy and leads to near absent levels of certain brain chemicals, serotonin and dopamine, that are critical for movement, behavior, and sleep.

SUV39H2: A direct genetic link to autism spectrum disorders
(RIKEN) New research from the RIKEN Center for Brain Science (CBS) in Japan has identified a direct link between the SUV39h2 gene and the development of autism spectrum disorders (ASD). A human variant of the SUV39H2 gene led researchers to examine its absence in mice. Published in Molecular Psychiatry, the study found that when absent, adult mice exhibited cognitive inflexibility similar to what occurs in autism, and embryonic mice showed misregulated expression of genes related to brain development.

Study finds vaccine hesitancy lower in poorer countries
(Innovations for Poverty Action) New research published in Nature Medicine reveals willingness to get a COVID-19 vaccine was considerably higher in developing countries (80% of respondents) than in the United States (65%) and Russia (30%). The study provides one of the first insights into vaccine acceptance and hesitancy in a broad selection of low- and-middle income countries (LMIC), covering over 20,000 survey respondents and bringing together researchers from over 30 institutions.
