The protein on human cells that tick-borne encephalitis virus (TBEV) uses for infection has now been identified—a major step toward understanding how TBEV causes neurological disease and for developing antiviral drugs. The study, co-led by scientists at Albert Einstein College of Medicine, Karolinska Institutet, and the United States Army Medical Research Institute of Infectious Diseases (USAMRIID) published today in the journal Nature.

Carriers of Robertsonian chromosomes are often unaware they’re different. Although generally healthy, they can be infertile or suffer miscarriages. When they do have children, they’re at increased risk of having Down syndrome. Now, in a landmark study, scientists at the Stowers Institute for Medical Research have identified the precise location where human chromosomes break and recombine to form Robertsonian chromosomes. The findings, published in Nature on September 24, 2025, not only explain how these rearrangements form and remain stable—but also point to how repetitive DNA once dismissed as “junk” may play a central role in genome organization and evolution.

An international team of researchers led by Dr Manel Esteller, head of the Cancer Epigenetics Group at the Josep Carreras Leukaemia Research Institute, has just published the most comprehensive analysis to date of the longest-lived person ever recorded, the Catalan woman Maria Branyas, who passed away at the end of 2024 at the age of 117. The peer-reviewed study, published in the prestigious international journal Cell Reports Medicine, concludes that the biology of supercentenarians is more complex than previously thought, and that the key may lie in a delicate balance between opposing forces.
