Cancer cells are known for their “glutamine addiction,” but many can escape this weakness by switching to alternative fuels. Researchers found that vitamin B7 acts like a metabolic “license,” enabling this escape route through a key enzyme. Without biotin, cancer cells lose that flexibility and stop growing. Mutations in a cancer-linked gene can make this vulnerability even stronger, offering a promising new target for therapy.

Кремниевый король: Как NVIDIA заложила фундамент нейросетевой революции

Как компания, чьи чипы изначально предназначались для отрисовки полигонов в видеоиграх, стала главным бенефициаром ИИ-революции и пробила потолок капитализации в $5 трлн? Это не просто история удачного стечения обстоятельств или криптобума. В этой статье мы разберем инженерную анатомию монополии NVIDIA: от едва не обанкротивших стартап «квадратных» полигонов в чипе NV1 до многомиллиардной ставки на платформу CUDA, которая превратилась в самый надежный вендор-лок современной индустрии.

От виртуальных рук до ИИ для выживальщиков: любопытные открытые агентные ОС [и один хардверный проект]

Операционные системы (ОС), в которых ИИ-агенты решают поставленные задачи и взаимодействуют с интерфейсами программ, — это «новый черный». Мы в Beeline Cloud решили рассказать о нескольких таких открытых проектах. Среди них: OpenFang, где за исполнение действий отвечают модули-«руки», проект, позволяющий управлять планировщиками Linux и даже модульный полевой компьютер с ИИ-помощником, который может пригодиться в постапокалипсисе дикой природе без связи с миром.

Scientists at UT Southwestern have uncovered a surprising new “master switch” that helps control how much cholesterol the liver sends into the bloodstream. The newly identified protein, HELZ2, works by shutting down the genetic instructions needed to produce apoB — a key building block of the cholesterol-carrying particles linked to clogged arteries and heart disease.

By temporarily blocking two proteins, researchers turned these cells into far more effective cancer fighters against difficult cancers like leukemia, glioblastoma, kidney cancer, and triple-negative breast cancer.

A massive international study could upend 40 years of heart attack treatment. Researchers found that beta blockers—routinely prescribed after uncomplicated heart attacks—offered no real benefit for patients whose heart function remained normal, despite being given to millions worldwide. Even more surprising, women taking the drugs faced a higher risk of death, repeat heart attack, or hospitalization for heart failure compared to women who didn’t receive them. Read more
