Imagine tiny, self-organizing brain models grown from stem cells. These are brain organoids, one of the 21st century's biggest scientific advancements. They mimic the structure and function of human brains. But as they get more complex, they raise new legal questions. What if they become conscious o
Ever wondered why some trees are more appealing to certain pests? Meet Casuarina equisetifolia, a coastal tree that's a favorite snack for the wood-boring pest Anoplophora chinensis. These pests love to munch on Casuarina trees, but scientists found something interesting: a molecular switch called C
Virus-like particles (VLPs) are a cool way to carry genetic material to specific places in the body. They can be tweaked for better delivery or to cause a desired immune response. Currently, VLP production might need different purification methods, which complicates things. Researchers came up with
The rise of cryptocurrencies like Bitcoin and Ethereum has unlocked a mountain of detailed transaction data. Unlike traditional cash, this data allows for in-depth research into detecting unusual activities, combating money laundering, and understanding user behavior. One way to analyze this vast am
As technology moves forward, traditional electronics face limits. For instance, Boltzmann's law and short-channel effects pose issues for metal-oxide-semiconductor field-effect transistors (MOSFETs). But there's a new kid on the block: nanoscale air channel transistors (NACTs), which use a vacuum-li
Scientists have long known that nickel-iron catalysts are great at producing oxygen from water, especially in alkaline conditions. But how they do it so well was a mystery—until now. A recent study looked at a special catalyst, nickel-iron phosphide (NiFeP), which is super active and stable. It only
Ever heard of gold nanoclusters? They're tiny gold particles, wrapped in protective layers called ligands. These clusters are made up of smaller gold units, often triangular or tetrahedral in shape. Think of them as miniature building blocks. Scientists have been trying to figure out how these block
Ambrosia beetles, known for their penchant for farming fungus while munching on wood, are a threat to trees. These crafty critters have a unique talent: spotting stressed plants that emit ethanol. To keep them away from valuable crops, scientists have suggested using ethanol-injected trees as decoy
Scientists are always on the hunt for better ways to split water into hydrogen and oxygen. This time, they've designed special Ru-B-Cr parts within RuO₂ nanofibers to make the Ru sites more active. This overcomes the hurdles of RuO₂ catalysts, which usually aren't very good at producing hydrogen and
Scientists have been trialing a new signal-processing image analysis technology in hospitals to check out suspicious colored moles that were sent for biopsies. This technology, called Moletest, was tested on an iPadPro11 by using four different versions of its analysis software. The main goal was to
