  1. Running scared

    Pavlovian fear conditioning triggers active fear responses as well as freezing.

  2. Immobilizing pancreatic cancer

    A protein known as CYRI-B is required for cancer cells to spread in a mouse model of pancreatic cancer.

  3. Decoding viral diversity

    New research reveals how genetic variability helps shape the biophysical properties of a key SARS-CoV-2 protein.

  4. Swabbing for safer births

    Measuring the levels of proteins related to antimicrobial immune responses in the vaginal fluids of pregnant individuals helps predict those at higher risk of giving birth early.

  5. Gene family of thousands

    Zebrafish have many more immune system genes than previously thought.

  6. Using community-sourced data to measure biodiversity

    Community-sourced species observation data is generally accurate and can help scientists and stakeholders keep track of biodiversity in different regions.

  7. Blades of grass and long faces

    New analyses help to reveal the evolutionary pressures that gave rise to the trunks of modern elephants.

  8. Evading the immune system

    A protein from human cytomegalovirus interacts with HLA-I molecules to prevent the immune system from detecting infected cells.
