Lead pollution hurts barley plants in many ways. It slows growth, damages the photosynthetic machinery, and lowers key minerals like calcium and potassium. The plants also suffer from more cell damage, shown by higher levels of harmful molecules such as MDA and hydrogen peroxide. In a separate group
Jean‑Martin Charcot, a key figure in early neurology, is remembered this year as part of his 200th birthday. He worked in Paris and helped shape modern brain study, while also becoming a friend of writer Alphonse Daudet. Their friendship later soured because Daudet, who had a serious nerve disease,
A recent study from several hospitals across Japan looked at how two different kinds of PET scanners perform when used for breast imaging. The first type is a “ring‑shaped” machine that surrounds the patient, while the second uses an “opposite‑type” design that places detectors on opposite sides. Re
Fungi can change their shape on the fly. When the outside world shifts, they switch between cell forms to survive or infect. Scientists know a lot about the genes that trigger these changes, but they have not looked closely at what fuels them. A new study shows that the sugar‑processing rou
A new research project in Italy tested a tool that measures how well couples bounce back from stress. The scale, called the Couple Resilience Inventory (CRI), was translated and checked with 360 people from a wide age range, most of whom were women. The study looked at how the questions fit together
Plants and the microbes that help them survive harsh weather can be made stronger by boosting a natural compound called glycine betaine. This molecule helps cells keep the right balance of water and protects them from heat, salt or drought. Traditionally, betaine comes from plants grown in specific
A fresh approach lets scientists watch glycine receptors in action at the nanometer level. Glycine receptors, which help dampen nerve signals, have been hard to study because usual fluorescent tags interfere with their normal behaviour. The new design attaches a chloride‑sensitive dye, mClYFP, to th
People often talk about the bad sides of social media. But what if we look at how it can actually help us feel more connected and purposeful? A recent study tried to do just that. It looked at why people use social media and how that relates to their sense of meaning in life. The study involved nea
Deep in a cave in Italy, scientists made an astonishing discovery. They found the remains of a teenager who lived 12, 000 years ago. This young person had a rare condition that affected her bones. Her arms and legs were much shorter than usual. This condition is called acromesomelic dysplasia, Marot
Deep beneath California's north coast, a seismic puzzle is unfolding. Scientists have uncovered hidden fault lines, revealing that the earthquake risk in the region might be much higher than we thought. The Mendocino Triple Junction, a hotspot where three tectonic plates meet, is more complex than p
