Columbia plans a costly upgrade that will swap out almost 54, 000 electric meters and about 53, 000 water meters for new digital versions. The goal is to stop the old system’s slow hand‑reading, broken devices and hidden leaks by letting data travel wirelessly to the city’s computers. The plan sa
China has spent decades building a powerful weapons industry. The country now appears in the top five worldwide when it comes to selling military gear, according to a respected global tracker. Yet the real story is more nuanced than those numbers suggest. A key problem is that China’s armaments hav

Cleaning water before it reaches our taps often involves adding chlorine to kill harmful algae. But algae have a clever trick—they wrap themselves in sticky layers called extracellular polymeric substances, or EPS. These layers act like shields, protecting the algae from chlorine’s effects. Scientis
Caleb Williams wasn’t born with a football in his hands and a dream of greatness. At ten years old, after a tough loss where his team couldn’t score, he got benched— not for bad play, but for too much energy. Instead of quitting, he decided then and there that he’d never let his team feel that way a

This time, an IT firm called EKI-Digital—already under fire for possible overbilling—sent a $250 donation to the mayor’s campaign. The timing is awkward. Just last year, the

CD8⁺ T cells are the body’s frontline defenders against viruses. When HIV takes hold, these cells become overworked and lose their power. Doctors give patients antiretroviral therapy (ART) to stop the virus from multiplying, but many immune problems linger. Scientists used a new technique tha
Cotton can grow in many places, but salty soil is a big problem. The plant first feels the salt as water pressure changes and then later deals with too many ions inside its cells. Cotton’s reaction is a teamwork of sensors on the cell wall, channels that let ions in or out, and calcium signals that
