Scientists have found a way to make quantum‑dot LEDs that shine brighter and last longer. The trick is to insert a special layer called a bilateral charge‑generation layer, or CGL. This layer has two parts that work together: one made from PEDOT:PSS and ZnO, the other from TAPC and HAT‑CN.
Many famous faces started out as ordinary people in small towns. Some were classmates, neighbors or childhood friends before the red carpets arrived. A young Hilary Duff rode bikes with future fans in Houston, while Barack Obama’s college roommate remembers him lending a hand to servants in Pakistan
Scientists have found a way to make a gout drug less likely to trigger the immune system. The drug, uricase, normally comes from a fungus called Aspergillus flavus and can cause allergic reactions in some patients. Researchers attached very small particles, called carbon dots, made from citric acid
Kevin Warsh, a former Fed official, has sparked debate by saying the central bank should stop using forward guidance and its famous dot plot chart. The dot plot shows where each Fed governor expects short‑term interest rates to go, and investors use it to judge company valuations. Warsh argues that
Neighbors can surprise you in the worst ways when free stuff enters the picture. Take the case of someone who offered a bright yellow paint can on a local app. A neighbor grabbed it for her front door, then demanded a full refund for the "wrong color, " claiming it ruined her curb appeal. Instead of
The James Webb Space Telescope has turned the sky into a gallery of tiny, bright red spots that scientists call little red dots, or LRDs. These points appear in nearly every deep‑field image the telescope captures and have puzzled astronomers since Webb began its mission four years ago. Astronome
Oscar winners have their own quirks about where they keep the shiny statues that symbolize career peaks. Some stash them in fancy museums, others hide them under beds or on kitchen counters. The choice often reflects personal comfort, privacy needs, or a touch of humor. One veteran actor leaves his
Carbon quantum dots, or CQDs, are like tiny solar panels that can clean polluted water. They work because their surfaces can be tweaked, and they separate electric charges very well. Scientists have shown that these dots can break down nasty chemicals such as antibiotics, dyes, and phenols with high
Perovskite nanocrystals are tiny particles that show great promise for use in various technologies. They can emit light very efficiently. But there's a catch. They have a problem with something called reabsorption. This is when the light they emit gets absorbed again. This makes them less useful for
Heart failure is a big problem worldwide, especially in places where advanced medical care is hard to get. This is where yoga might come in handy. The Yoga-EndOmics study is looking into how yoga can help people with heart failure. It's not just about stretching and breathing exercises. This study w
