Ebola Reaches Nigeria as Outbreak Becomes Most Geographically Widespread in History
Nigeria confirmed its first Ebola case in Abuja after a woman who travelled from Uganda tested positive, while Kenya reported its ninth case on the same day. The ongoing outbreak — rooted in the DRC with over 9,000 cases and 4,381 deaths — is now the most geographically widespread Ebola outbreak ever recorded.
FDA Approves Hibsago: First Antisense Drug for Chronic Hepatitis B
The US Food and Drug Administration approved Hibsago (bepirovirsen), a first-of-its-kind antisense oligonucleotide injection made by GSK, for adults with chronic hepatitis B who meet specific criteria. In trials, 24% of patients who received Hibsago were later able to stop all hepatitis B medication — versus none in the placebo group.
OpenAI Acquires Drug-Development Platform Orchestra Bio to Accelerate Medicine Discovery
OpenAI acquired Orchestra Bio, a startup that deploys AI agents to manage pharmaceutical drug-development pipelines, integrating it into Rosalind, its life-sciences AI suite. The move is part of a wider AI-industry push to use agents to compress drug development timelines from over a decade to just a few years.
Scientists Reveal Why Statins Can Damage Muscles — and Point to a Fix
Researchers at the University of British Columbia used cryo-electron microscopy to show that statins latch onto a calcium-regulating protein in muscle cells and force it to stay open, causing damaging calcium leakage. The molecular discovery, published in Nature Communications, opens the door to redesigning statins to retain their cholesterol-lowering benefits without the side effects.
Blocking Immune T Cells Protects Brain Tissue in Alzheimer's — Without Removing Toxic Protein
Washington University scientists found that blocking CXCR3, a protein that helps immune T cells enter the brain, preserved around 40% more memory-centre tissue and improved memory in mice with tau accumulation — without reducing the tau itself. The study, published in Neuron, points to the immune response as a key driver of neurodegeneration, independent of toxic protein build-up.
