The new sensor uses a single CRISPR enzyme, Cas12a, to spot damaged DNA without extra steps. A specially designed double‑stranded DNA keeps Cas12a quiet until the enzyme uracil‑DNA glycosylase (UDG) removes a uracil base. When UDG cuts the uracil out, the balance of the DNA changes and Cas12a
Older people in Brazil are showing that a strong personal faith can help them feel happier and less sad, which in turn lets them live better lives as they age. A study of 538 seniors aged 60 to 101 measured how satisfied they were with life, how much depression they felt, and how well they aged. Par
Scientists used a powerful X‑ray machine in Germany to scan over two thousand ants from museums and private collections. The device, a synchrotron particle accelerator, captured detailed images of each insect’s body in a single week. Normally, doing the same work would take years with older technolo
Three scholars from rural America, two of whom identify as queer—one Two‑Spirit and one transgender—took part in a gathering where people shared stories across age groups. They chose to study the event through collaborative autoethnography, a method that blends personal experience with academic anal
Arri, a long‑time name in movie cameras and lights, has joined forces with Honor, the phone maker behind the soon‑to‑arrive Robot Phone. The deal lets Arri’s image science work inside Honor devices, giving mobile users a taste of cinema‑grade picture quality. The partnership shows how film technolo
Pet ownership might be a hidden helper for keeping the mind active as people age. New studies show that living with animals can touch many parts of how our brains change over time. The research looks at both the body’s biology and the feelings that come with having a pet. On the biological side, pe
People’s ideas about getting older influence how they feel and what habits they adopt. In a recent survey across Iran, researchers looked at this link for the first time. The study gathered data from adults of different ages, asking them how they see themselves as they age. Questions covere
Scientists are turning to a special imaging trick that makes the normally invisible flow of energy inside cells visible. By feeding cells a version of pyruvate that glows brighter than usual, researchers can watch how it turns into lactate in real time. The key to understanding this process lies in
Perfluoroalkyl and polyfluoroalkyl substances, or PFAS, are called “forever chemicals” because they linger in the body for many years. A new study looked at how these substances might make men feel older than their calendar age. The researchers found that the link between PFAS levels in the blood an
The COVID‑19 crisis forced the United Kingdom to stop many everyday activities and shut large parts of its economy. Researchers wanted to know how well the public stuck to new rules, especially social distancing, and whether government messages helped people follow them. An online survey asked 1, 0
