"A Vaccine May Prevent Alzheimer's A landmark real-world experiment gave the strongest evidence yet that the shingles vaccine could lower the risk of Alzheimer's disease and other forms of dementia, finally giving concrete data to support a longtime hunch that viruses may somewhat increase dementia risk. People in Wales who received the shingles shot were 20 percent less likely to develop dementia over the next seven years compared with those who did not get it."
"Human Embryo Implantation in 3D For the very first time, researchers captured incredible real-time, three-dimensional images and videos of a human embryo implanting into artificial uterine tissue. This implantation used a lab matrix that was not designed for in vitro fertilization (IVF), but the study's authors said the new footage of the reproduction stage could potentially inform better IVF techniques. Implantation failure is one of the main causes of infertility and miscarriages."
Despite funding cuts and governmental departures from evidence-based studies in 2025, medicine made notable progress across several areas. A real-world study in Wales found people who received the shingles vaccine were 20 percent less likely to develop dementia over seven years. Researchers captured the first real-time, three-dimensional images and videos of a human embryo implanting into artificial uterine tissue, using a lab matrix not designed for IVF and offering potential to improve implantation success. A daily nonhormonal oral male contraceptive passed early-phase safety trials in humans, representing a new option beyond condoms and vasectomies.
