In 2025, significant progress was made in understanding human evolution, particularly through the genetic analysis of fossils like the Dragon Man skull, which has been linked to Denisovans, revealing new insights into ancient human species and their interbreeding with modern humans. Additional discoveries, including a high-coverage Denisovan genome from a 200,000-year-old tooth, are expected to further unravel the complex history of human ancestry in the coming years.

Recent advances in DNA sequencing have revealed that the so-called 'first Black Briton,' Beachy Head Woman, was actually from southern England with fair skin and light features, challenging earlier assumptions based on skull measurements that suggested sub-Saharan African origins. This highlights how technological progress can refine our understanding of historical figures.

Scientists have discovered that beta-HPV, a common virus previously thought to only contribute to skin cancer indirectly, can directly drive cancer growth by integrating into the DNA of tumor cells, especially in immunocompromised individuals. A case study of a woman with an inherited immune disorder showed that her cancer was caused by the virus, which was successfully treated with a stem cell transplant, highlighting the importance of personalized cancer therapies and the role of immune health in cancer development.

The Xerces blue butterfly, native to California and last seen in 1941, was confirmed as the first American insect species driven to extinction by human activity, with recent genetic analysis proving its distinctness from similar species. Despite its extinction, the butterfly's genome has been sequenced, raising possibilities for future de-extinction efforts, amidst ongoing concerns about insect declines and ecosystem health.

A large study suggests that no level of alcohol consumption is safe for the brain, with even light drinking increasing dementia risk, supported by observational and genetic analyses indicating a causal relationship. The findings challenge previous beliefs that moderate drinking might be protective and highlight alcohol reduction as a potential strategy for dementia prevention.

A study reveals that beta-HPV, previously thought to only contribute to skin cancer indirectly, can directly drive cancer growth by integrating into the DNA of tumor cells, especially in immunocompromised individuals. A woman's case with inherited immune disorder demonstrated that replacing her dysfunctional T cells with healthy ones through a stem cell transplant successfully treated her aggressive skin cancer, highlighting the importance of personalized treatments and the role of immune health in cancer development.
