Copper nanoparticles that glow in the dark are being tweaked so they shine brighter and last longer inside tiny point‑of‑care test kits. Scientists are using two tricks: covering the particles with a protective polymer (polyacrylic acid) and letting them clump together when special metal ions are ad
Many school programs that teach farming and food business miss a crucial lesson: keeping crops, livestock, and markets safe from disease and danger. Research looked at 199 college classes that cover agriculture and business. Only eight of those courses, about 4%, mentioned any idea about protecti
Cyanobacteria, often called blue-green algae, can create a big problem in water. They release something called microcystin-LR (MC-LR), which is bad for plants, animals, and even people. One of the main ways MC-LR hurts living things is by causing something called oxidative stress. This stress leads
Plants have a clever chemical called salicylic acid that acts like an alarm system when attackers arrive. In the common lab plant Arabidopsis, scientists first mapped out how this alarm works: a special route called the isochorismate pathway makes salicylic acid, proteins named NPR bind to it, an
In the world of mental health, doctors often rely on people telling them how much they drink. This can be tricky because memories and honesty are not always perfect. A new approach uses tiny gadgets that sit on the skin to detect alcohol molecules as they leave the body. The devices read chemical si
Wolfberry, also known as goji berry, is a superstar in the plant world. It's packed with nutrients and has amazing medicinal benefits. But there's a big problem: root rot disease. This nasty issue can really mess up the plant's growth and quality. Scientists have found a cool solution to this proble
Rubber trees, the main source of natural rubber, face tough times when water is scarce. Scientists decided to see how these trees handle drought. They looked at how the trees react physically and how their genes behave under different water conditions. First, they compared trees that got plenty of
Pulse Biosciences is stepping into the spotlight at a big healthcare event. They're set to showcase their unique technology at the 44th Annual J. P. Morgan Healthcare Conference in San Francisco. This isn't just any tech, though. It's called nPulse™, and it's all about using tiny bursts of electrica
Lactate is a substance your body makes during exercise or when you're sick. Doctors need to measure it to understand your health. But there's a problem: too much lactate can mess up the tests. Scientists have found a solution. They made a tiny tool, a biosensor, to measure lactate accurately. This
In the ongoing battle against harmful germs and the growing issue of antibiotic resistance, scientists have made a significant discovery. They've created a new type of material that's both safe and highly effective at tackling these health threats. This new material is called a covalent organic fra
