The new sensor turns on a light signal when it finds the cancer marker CEA. It uses a tiny piece of DNA that sticks to CEA and a special nanoparticle made from cerium and zinc called Ce‑UiO‑66. The particle is a super‑quencher: it almost completely hides the DNA’s glow until CEA binds. Scient
A new skin‑attached device can keep working for three weeks without a battery, thanks to wireless power from a phone or wrist reader. The patch draws electricity from the nearby device’s magnetic field and uses it to refresh its sensor surface, so it stays accurate over time. The technology was c
Betty Broderick spent most of her adult life behind bars. She was 78 when she died in May 2024. Her story became famous not just because of the crime she was convicted of, but because it touched on themes many people find hard to ignore: love turning sour, betrayal, and the blurred line between vict
In 2023, researchers surveyed 200 nursing students to see how their inner resources affect their sense of right and wrong. The study measured three things: psychological capital (confidence, hope, resilience), spiritual well‑being (a sense of purpose and connection), and moral sensitivity (the abil
A tiny gadget might soon help spot serious illnesses just by checking your spit. Scientists built a sensor using carbon nanotubes and transistors to catch a key inflammation marker called interleukin-6 (IL-6). This protein shows up in higher amounts when cancer spreads or during major infections lik
Tech companies often chase the next big idea without stopping to ask who’s missing from the conversation. At a recent industry gathering, three leaders shared how unexpected perspectives shifted their approach to crypto products, policies, and hiring—proving that diversity isn’t just about fairness,
Detecting ammonia isn’t just about avoiding bad smells—it’s about safety. This gas can harm workers in factories, pollute the environment, and linger in poorly ventilated spaces. Traditional sensors often struggle because they either pick up ammonia too slowly or take too long to reset. A new approa
Some jokes don’t travel well across borders. A comedy that makes one country laugh might make another angry enough to ban it outright. A classic example is Life of Brian, nearly half a century old yet still risky to screen in Germany under certain rules because its jokes push religious buttons. Even
Scientists have spent decades charting how our eyes, ears and skin send signals to the brain. The nose, with its thousands of scent sensors, seemed a chaotic maze. Most researchers thought the receptors were scattered randomly. Two research groups changed that view. They used DNA sequencin
When you push your body for two hours on a bike, something odd happens with pain. Scientists call it exercise-induced hypoalgesia—your pain radar drops after intense movement. Most studies focus on short bursts, but this one checked what happens after a steady, long ride. Twelve trained male cyclist
