Scientists have long used a material called Me‑4PACz, or Me4, as a layer that pulls holes out of inverted perovskite solar cells. The layer is handy, but it often clumps together in solution and does not spread well over the next layer. Because of this, the contact between layers is weak and the cry
Zinc metal batteries are seen as a great option for affordable and eco-friendly energy storage. However, they have a big issue: zinc ions struggle to move around efficiently. This is because they stick too much to water molecules, causing uneven growth and other problems. To tackle this, scientists
Kit Harington, known for his serious role as Jon Snow in "Game of Thrones, " showed a different side of his talent in a lesser-known HBO project. This project, a sports spoof called "7 Days in Hell, " is a hilarious mockumentary that many fans might have missed. It's about a never-ending tennis matc
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
A big winter storm is coming to the US. It might affect a huge area, from Texas to New England. People should get ready for snow, ice, and very cold temperatures. These conditions could cause power outages and other problems. The storm, named Winter Storm Fern, is expected to start on Friday. It wi
George Kittle, a tight end for the San Francisco 49ers, has a surprising take on Philadelphia Eagles fans. While many players complain about the hostile environment at Lincoln Financial Field, Kittle sees it differently. He appreciates the equal treatment all visiting teams receive from Eagles suppo
Aqara just launched a new smart lock, the U400, at CES 2026. It's packed with cool features, like UWB technology. This tech lets you unlock your door without even taking your phone out of your pocket. It's like magic, but with science! The U400 uses UWB chips in iPhones to unlock the door as you ap
Piezoelectric materials are special because they can turn mechanical energy into electrical energy and vice versa. Now, scientists are making these materials clear, like glass, which opens up new possibilities. These clear materials can be used in things like medical devices, acoustic systems, and e
In the world of materials science, perovskite oxides are like the superheroes of energy conversion. They have a special power: they can conduct both ions and electrons. This makes them perfect for solid oxide fuel cell (SOFC) cathodes. But there's a catch. Most of these materials have a crystal stru
Brain science is moving fast. Scientists are creating things like brain organoids and human-animal chimeras. These advances raise big ethical questions. Western bioethics has been the main guide, but it might not be enough on its own. Enter Nishida Kitarō, a Japanese philosopher. His ideas focus on
