Your Brain Might Be Older Than You Think – And It Could Explain Memory Loss - Using machine learning and brain scans, researchers found that accelerated brain aging increases the impact of cognitive risk factors on memory and thinking, particularly in people with cerebrovascular disease. The difference between a person’s predicted brain age and their actual age, known as the...
Giving a Drum MIDI Input with Lots of Solenoids - As far as giving mechanical instruments electronic control goes, drums are probably the best candidate for conversion; learning to play them is challenging and loud for a human, but they’re …read more
Dinosaur Ancestors Trekked 10,000 Miles Through “Hell” on Earth - First study to explore how ancient reptiles spread across the Earth after the end-Permian mass extinction. New research suggests that the ancestors of dinosaurs and crocodiles in the Triassic period were able to migrate across regions of the ancient world that were once thought to be entirely uninhabitable....
Retrotechtacular: 1970s Radio - Before YouTube, you had to watch your educational videos on film. In the 1970s, if you studied radio, you might have seen the video from Universal Education and Visual Arts, …read more
MIT’s Window-Sized Device Pulls Drinking Water From Thin Air, Even in the Desert - MIT engineers have created an atmospheric water harvester that can generate fresh water in any location, including extreme environments like Death Valley, California. Today, 2.2 billion people around the world do not have access to safe drinking water. In the United States, over 46 million people face...
3D Print Glass, Using Accessible Techniques - When seeing a story from MIT’s Lincoln Labs that promises 3D printing glass, our first reaction was that it might use some rare or novel chemicals, and certainly a super-high-tech …read more
Quantum Time-Freeze: Lasers Lock Quantum States 1,000x Longer - By using tailored pulses of light and powerful X-ray techniques, scientists have discovered how to create long-lived, light-induced quantum states in a copper oxide material—something previously thought to last only trillionths of a second. This breakthrough allows electrons to tunnel and become trapped...
Building Diode and Diode-Transistor Logic Gates - The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic …read more
Photogrammetry takes to the skies - Maybe your goal is to preserve the heyday of rail travel with a precise scale replica of a particular railroad station. Maybe you’re making a hyper-local edition of Monopoly in …read more
Staying Positive Could Protect Against Middle-Aged Memory Loss, 16-Year Study Reveals - Researchers from the US, UK, and Spain tracked more than 10,000 people over the age of 50. Higher levels of well-being may help lower the risk of memory loss in middle age, according to new research that followed more than 10,000 adults over the age of 50 for 16 years. The findings, published in the [...]...
Scientists Crack the 500-Million-Year-Old Code That Controls Your Immune System - A collaborative team from Penn Medicine and Penn Engineering has uncovered the mathematical principles behind a 500-million-year-old protein network that determines whether foreign materials are recognized as friend or foe. How does your body tell the difference between friendly visitors, like medications...
If Your Kernel Development is a Little Rusty - To paraphrase an old joke: How do you know if someone is a Rust developer? Don’t worry, they’ll tell you. There is a move to put Rust everywhere, even in …read more
