How Google’s Earthquake Alerts Protected Millions — And How to Turn It On in Quake-Prone Countries When two massive earthquakes (7.2 and 7.5) struck Venezuela recently, the country had no national early warning system. But millions of Android phones lit up with loud alerts seconds to minutes before the shaking hit — giving people precious time to drop, cover, and hold on. Google’s clever system turns the accelerometers in over 2 billion Android phones into a giant crowdsourced seismic network. It detects the first waves, confirms the quake, and blasts notifications to users in the affected area. In Venezuela, it reached 11.4 million people — proving technology can save lives even where governments can’t. How to activate it (works in nearly 100 countries): Open Settings on your Android phone. Tap Safety & Emergency (or search for “Earthquake alerts”). Select Earthquake Alerts and toggle it ON. Keep Location services ena...
Bioprinting: From Sci-Fi Fantasy to Cutting-Edge Reality The world of science fiction is no stranger to the concept of bioprinting - the creation of living tissues and organs using 3D printing technology. But what was once relegated to futuristic films is now rapidly becoming a reality. This trending technology has the potential to revolutionize healthcare, drug discovery, and even personalized medicine. Img credit: nerdist So, what exactly is bioprinting? Imagine a 3D printer that, instead of using plastic or metal, utilizes bioinks. These specialized inks are loaded with living cells and other biological materials, allowing scientists to carefully layer them and build complex structures that mimic the natural composition and function of human tissues. This opens a door to a world of possibilities, including: Regenerative medicine: Bioprinting could pave the way for repairing or replacing damaged organs with 3D-printed tissues grown from a patient's own cells. This could offer ne...
