  • Discovery of an ape virus in an Indonesian rodent species
    The gibbon ape leukemia virus (GALV) is a medically important tool in cancer therapies. GALV is a retrovirus pathogenic to its host species, the southeast Asian lar gibbon (Hylobates lar) and thought to have originated from a cross-species transmission and may not originally be a primate virus at all. An international research team screened a wide range of rodents from southeast Asia for GALV-like sequences. The discovery of a new GALV in the grassland melomys (Melomys burtoni) from Indonesian New Guinea supports the hypothesis that this host species, and potentially related rodent lineages in Australia and Papua New Guinea, may have played a key role in the spread of GALV-like viruses.

Revision of standards is needed to test sunglasses quality and establish safe limits for the lenses' UV filters, according to new research.
  • Designing ultrasound tools with Lego-like proteins
    Ultrasound imaging is used around the world to help visualize developing babies and diagnose diseases. Sound waves bounce off the tissues, revealing their different densities and shapes.
