マラリアは複雑なライフサイクルを持ち、免疫系をすり抜けるためワクチン開発が極めて困難な疾病だが、オックスフォードのジェンナー研究所で博士課程にあったキャサリン・コリンズ氏が第二のマラリアワクチンR21を共同発明。初のマラリアワクチンの期限切れ特許を基に、余剰なB型肝炎抗原を除去し、マラリア抗原の比率を高めた新製法と安価なアジュバントを組み合わせ、価格を約3分の1に抑え、大規模製造が容易で、より多くの子どもたちの命を救えるワクチンを実現したイノベーションの舞台裏を語る。
Scientists have developed a nasal spray treatment that reversed key signs of brain aging in animal studies. The spray delivers a molecule that restores cellular waste-clearing processes in the brain, improving cognitive function in older mice. Researchers hope to advance the treatment to human clinical trials.
Scientists showed a one-time gene therapy can lower LDL cholesterol by up to 60% for over a year in monkeys, offering a potential alternative to daily statins for heart disease prevention.
Arc Institute has raised $2.1 billion and secured a Nobel Prize for its work on programmable biology and RNA medicine, aiming to move beyond incremental drug development toward a systematic "constellation" approach to curing previously untreatable diseases. The institute's model combines academic freedom with long-term funding to tackle fundamental biological challenges.
Pancreatic cancer is notoriously difficult to treat due to the dense, protective tissue surrounding tumors, but a new drug combination targeting a specific protein called KRAS may offer a breakthrough. Clinical trials show promising results in shrinking tumors and improving survival rates, potentially transforming the outlook for one of the deadliest cancers.
Colorectal cancer rates are increasing among younger adults, but the article urges caution in interpreting the trend, noting that absolute risk remains low and that the rise is partly due to improved detection and screening practices.
