New structure found inside human cells could radically change health and medicine

Image
  Breakthrough discovery Announced on June 25, 2025, by University of Virginia and NIH researchers, the hemifusome is an organelle formed by two vesicles partially fused through a “hemifusion diaphragm.” It's been visualized via cryo-electron tomography and acts as a “loading dock” for cellular cargo—sorting, recycling, and processing materials. The structure is surprisingly common and shows up in various cell types, though it had been hidden until now. “Snowman in a scarf” image Dubbed the “snowman wearing a scarf” by media due to its distinctive shape (two circular vesicles connected by a thin membrane), this organsheet could unlock new biomedical insights. Broad impact on health Hemifusomes are implicated in diseases involving vesicle trafficking—such as Hermansky–Pudlak syndrome, neurodegenerative diseases like Alzheimer’s and Parkinson’s, and possibly other genetic or immune disorders. Researchers describe them as a potentially revolutionary diagnostic and therapeutic ta...

New “evolution engine” creates super-proteins 100,000x faster

Image
  "This is like giving evolution a fast-forward button," says co-senior author Pete Schultz, the President and CEO of Scripps Research, where he also holds the L.S. "Sam" Skaggs Presidential Chair. "You can now evolve proteins continuously and precisely inside cells without damaging the cell's genome or requiring labor-intensive steps." Directed evolution is a laboratory process that involves introducing mutations and selecting variants with improved function over multiple cycles. It's used to tailor proteins with desired properties, such as highly selective, high-affinity antibodies, enzymes with new specificities or catalytic properties, or to investigate the emergence of resistance mutations in drug targets. However, traditional methods often require repeated rounds of DNA manipulation and testing with each round taking a week or more. Systems for continuous evolution -- where proteins evolve inside living cells without manual intervention -- a...

Genetic Ancestry of Modern-Day Indians

Image
  Recent research reveals that modern-day Indians likely descend from three ancestral groups linked to Iranian and Central Asian cultures. This study published in the journal Cell provides vital information about the genetic history of India, denoting the complex interactions of migration and social practices over thousands of years. Ancestral Groups The study identifies three main ancestral groups. These are Neolithic Iranian farmers, Eurasian Steppe pastoralists, and South Asian hunter-gatherers. Each group contributed to the genetic makeup of contemporary Indians. These contributions reflect ancient migrations that shaped the population’s genetic diversity. Migration Patterns Genetic evidence suggests that the initial migration to India occurred around 50,000 years ago from Africa. This migration laid the foundation for the genetic structure of Indian populations. Subsequent gene flow from Neanderthals and Denisovans added 1-2 per cent to the genetic composition of modern India...
