A study of 4,918 schizophrenia-associated variants found three age-ordered subsets that persistently contribute to the heritability of the disease. The "Young" subset, concentrated in brain-regulatory genes, accounted for a significant fraction of schizophrenia's genetic architecture and showed strong correlations with East Asian schizophrenia, bipolar disorder, but not height or body-mass index.
Researchers have developed a system that enables precise control over songbird vocal learning, addressing the long-standing challenge of credit assignment in this complex behavior. The cortico-basal ganglia circuit can learn with millisecond-scale temporal precision and single-neuron spatial precision, allowing for targeted auditory feedback to improve song performance. This breakthrough has implications for understanding brain function and potentially informing the development of more advanced artificial learning systems.
Researchers analyzed fMRI data from 1,737 individuals with autism spectrum disorder (ASD) and found that hyperconnectivity and hypoconnectivity are distinct neurobiological phenomena, differing in molecular signatures and regional brain activity. Hyperconnectivity was linked to older participants and higher-order cortical regions, while hypoconnectivity was associated with subcortical systems and ASD's reorganization of the sensory-to-transmodal cortical gradient.
Researchers studied the vocal communication of Fmr1 knockout and wildtype rats to understand how Fragile X syndrome affects early vocal development in autism spectrum disorder. They analyzed ultrasonic vocalizations from 3-21 days old rats, finding that Fmr1 mutation disrupts the temporal organization of USVs, with significant changes observed across postnatal development.
A team of researchers has successfully engineered yeast strains to produce de novo L-(+)-tartaric acid through multi-modular biosynthetic pathways, leveraging modular gene clusters and optimized metabolic networks to improve yield and efficiency. This breakthrough could have significant implications for the production of fine chemicals and pharmaceuticals.
A new method called GraNPA has been introduced for performing GWAS-like analysis on pangenome variation graphs, reducing the need for additional population materials or kinship information for qualitative phenotypes, and preventing reference bias from variant calling. This approach uses a graph node-phenotype association framework to identify statistically significant shifts in phenotype scores within the graph, highlighting regions associated with specific traits.
Researchers found that sound-shape associations, as seen in the Bouba-Kiki Effect, are present in non-human primates, including macaques, suggesting a conserved perceptual bias across vertebrates. This discovery may have implications for understanding the origins of symbolic communication systems in humans. The study's findings contradict previous results on great apes and domestic chickens.
A vulnerability in the Amylyx patient education website, affecting versions 2.0.1 and earlier, exposes sensitive patient information to unauthorized access via SQL injection attacks, potentially compromising personal data of individuals with post-bariatric hypoglycemia. The issue was discovered through automated scanning and has been patched by the vendor.
A study using mice has found that microglia immune cells in the brain respond differently to ketamine anesthesia in males and females, suggesting sex-specific differences in brain recovery responses.
A new study reveals how infected cells use molecular signals to guide neutrophils to specific infection sites, bypassing damage to healthy tissue, but no cybersecurity information is provided.
The Trump administration is revising its rebate pilot for the 340B drug discount program, affecting over 1,700 hospitals and potentially increasing costs for patients. The changes, which include a shift from a tiered rebate structure to a single rate, are expected to impact pharmaceutical companies' discounts on discounted medications.
A preclinical study using Lactiplantibacillus plantarum-derived 10-hydroxystearic acid (10-HSA) showed promise in repairing HIV-related gut damage, reducing inflammation, restoring immunity, and improving antiretroviral therapy effectiveness in non-human primates. The findings support future human trials for this microbiota-derived compound as an adjunct to conventional HIV treatment.

A Daiichi Sankyo quarterly report revealed a significant accounting error, resulting in a $1.4 billion loss, while the company's manufacturing operations were also impacted by supply chain disruptions and production delays, affecting their pharmaceutical products. The error was attributed to a misclassification of inventory, which led to a write-down of $1.2 billion. This incident highlights the importance of accurate financial reporting and robust internal controls in maintaining business stability.
AbbVie's Skyrizi has surpassed Humira's sales, with $5.55 billion in Q2 revenue, matching its predecessor's record high, after seven years on the market, indicating its effectiveness as an IL-23 inhibitor replacement.

Pharma company Karyopharm is moving forward with its XPO1 inhibitor Xpovio after a new analysis revealed an indication of potential efficacy, following initial investor concerns over the March dataset. The updated findings suggest Xpovio may be effective against certain types of blood cancer, and Karyopharm plans to proceed with further development.
Novo Nordisk's phase 3 trial for ziltivekimab failed to meet its primary endpoint, casting doubt on the treatment's potential as a blockbuster medication; however, the company can still salvage the program through its ongoing Artemis and Hermes trials.
The FDA's advisory panel voted in favor of Replimune's experimental treatment for advanced melanoma, but the agency has previously rejected it twice; a successful trial with this treatment could change its status. The treatment targets cancer cells through CAR-T cell therapy, and if approved, it would be used to treat patients with advanced melanoma.
