Researchers at George Washington University found that extremist groups like Boogaloo and ISIS exhibit similar mathematical patterns in their online support, despite ideological differences. This knowledge can help social media platforms disrupt the growth of such groups.
Researchers analyzed genetic data from over 2,300 individuals with autism, identifying missense variants in 398 genes that may impact phenotypes. Patients with these variants tend to have lower IQ scores, shedding light on the complex relationship between mutations and autism severity.
Researchers discovered that phosphorylation of MECP2 protein decreases in brain cells as Alzheimer's disease progresses, while abolishing this phosphorylation enhances neuronal viability and gene expression. The study suggests that modifications of MECP2 could be a therapeutic target for developing specific therapies against AD.
A study published in The Journal of Bone & Joint Surgery found that total ankle replacement (TAA) provides better long-term function than ankle arthrodesis (AA) for patients with severe ankle arthritis. TAA resulted in improved patient-reported outcomes, including reduced pain and enhanced quality of life.
Researchers at the John Innes Centre identified a key gene controlling grain elongation and glume characteristics in Polish wheat, which could lead to improved productivity and sustainability in wheat production. The discovery highlights the importance of understanding genetic control of agronomic traits for major crops like wheat.
Researchers at University College London developed a robotic 'Third Thumb' that allows users to perform dextrous tasks with one hand. The study found that participants' brains adapted to the extra thumb, changing their natural hand movements and reporting it felt like part of their body.
A study of 43,000 reptile bone remains found that European colonization led to mass extinctions of 50-70% of snakes and lizards on the Guadeloupe Islands. The Indigenous populations had no impact on local reptile diversity.
The Canadian Syncope Risk Score is an accurate validated prediction score for emergency department patients with unexplained syncope. The study highlights the weaknesses of several risk tools previously published, and its impact on clinical decision making is not known.
The European Society of Endocrinology has confirmed the strong links between hormones and COVID-19, with evidence suggesting an 'endocrine phenotype' of the disease. Diabetes and obesity have emerged as comorbidities associated with severity and mortality of COVID-19.
Research finds herbivores weaken early emergers in California grass species, offsetting advantage of early germination. This discovery highlights the role of herbivory in shaping natural selection and evolutionary responses to global environmental changes.
The economic impact of Invasive Alien Species on Africa's agricultural sector is estimated to be $3.6 trillion a year, with cassava and citrus fruits being among the most affected crops. The study highlights the need for measures to prevent new species from arriving and established species from spreading.
