NASA’s Psyche spacecraft used Mars’s gravity for a slingshot maneuver to adjust its path

Planetary Science, Space & Environment /

NASA’s Psyche spacecraft used Mars as a gravity slingshot while traveling toward a metal-rich world that may help uncover what lies inside planets like Earth. On May 15, NASA’s Psyche spacecraft flew just 2,864 miles (4,609 kilometers) above Mars in a successful close pass. The spacecraft used Mars’ gravity to gain speed and adjust its […]

New technology may lower high blood pressure without drugs

Healthcare, Medicine /

Researchers at Pennsylvania State University in the United States have created a 3D-printed hydrogel implant that may offer a way to treat high blood pressure without medication. The device, named CaroFlex, was tested in rats by implanting it near the carotid artery. In short trials lasting about ten minutes, it reduced blood pressure by more

China has opened a school where humanoid robots learn real-world tasks

Applied Science, Robotics /

For years, artificial intelligence existed mostly on screens. Chatbots generated text, algorithms created images, and ever more advanced systems dominated the tech conversation. But away from traditional computers, a quieter race has emerged. The new challenge is no longer just teaching machines to think — it’s training humanoid robots to move, handle objects, and operate

Study suggests hantavirus may persist in semen for years

Healthcare, Medicine /

A 2023 study published in the scientific journal Viruses found hantavirus genetic material in semen up to six years after infection. Researchers focused on the Andes virus—a rare strain linked to the MV Hondius cruise ship outbreak and known for its ability to spread between humans. The study tracked a 55-year-old man who contracted the

A nasal spray for stroke patients can deliver medication to the brain without surgery

Applied Science, Neuroscience /

Scientists have developed the world’s first nanoparticle nasal spray for stroke, allowing brain drug delivery without surgery or injections. By bypassing the blood-brain barrier, it enables rapid use after symptoms appear, supporting early treatment, protecting brain cells, and reducing complications. The breakthrough was developed by researchers at The University of Hong Kong’s LKS Faculty of

Could this desktop robot with a projector for a head be the future of office work?

Applied Science, Robotics /

Amid growing interest in AI workplace tools, Lenovo unveiled its AI Workmate Concept at the Mobile World Congress, giving office chatbots a physical form with a face and built-in projector. The compact desktop robot has a 3.4-inch LCD “face,” cameras, and a Pico projector on a movable arm. It responds to voice and gestures, recognizes

Scientists can block pain signals before they reach the brain

Applied Science, Neuroscience /

For centuries, medicine has tried to manage pain by reducing symptoms or blocking nerve signals. Now, researchers are adopting a more radical approach: they are preventing pain before the brain becomes aware of it. Importantly, this work is already being tested in laboratories developing real-time neural technologies, not just remaining theoretical. Traditionally, pain treatment has

Scientists create menstruation-mimicking organoid to study tissue regeneration

Healthcare, Medicine /

Scientists have created organoids that regenerate in a way similar to the endometrium — the uterine lining that renews itself during every menstrual cycle. Detailed in the journal Cell Stem Cell, the discovery enables researchers to study in the lab a rare form of tissue repair seen in humans and could support future treatments for

Scientists create mini human heart that mimics arrhythmia

Healthcare, Medicine /

Mini Human Heart – Researchers at Michigan State University have developed a lab-grown mini heart that replicates atrial fibrillation, an arrhythmia causing irregular, rapid heartbeats. The condition impacts around 60 million people globally and has seen little progress in treatment over recent decades. A team led by Aitor Aguirre at MSU developed the model using
