LJI researchers reveal the first 3D structure of a protein from a human endogenous retrovirus. Human cells make this protein by expressing ancient viral DNA—and it's unlike anything seen before.

A newly-discovered species of a large, crocodile-relative predator has been described via a remarkably well-preserved fossil from Argentina, according to a study published August 27, 2025, in the open-access journal PLOS One by Fernando Novas from Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”, Argentina, and colleagues.

Researchers at Stockholm University have succeeded in creating a molecular blueprint of how one of the world's most dangerous toxins, botulinum toxin, is structured, stabilised, delivered and released. The research, published in the scientific journal Science Advances, paves the way for more effective drugs.

Pelvic organ prolapse (POP) affects millions of women, causing pain and diminished quality of life. Current options are limited, with surgery often the only choice. Lehigh University bioengineer Anand Ramamurthi, in collaboration with the Cleveland Clinic, has received NIH funding to develop a nonsurgical therapy using nanoparticles to regenerate pelvic tissue and slow or reverse POP progression.

Scientists at St. Jude Children’s Research Hospital found that droplets within cells, called condensates, are required for ependymoma formation, creating new opportunities for drug development.

Chemists at UCL (University College London) have shown how two of biology’s most fundamental ingredients, RNA (ribonucleic acid) and amino acids, could have spontaneously joined together at the origin of life four billion years ago.
