gizmodo.com Ed Cara 2026-03-18 05:10:52

Americans’ air is teeming with all sorts of known toxin pollutants—now scientists have found a new one to add to the list. Researchers at the University of Colorado Boulder detailed their discovery in a study published earlier this month. They sampled agricultural sites in Oklahoma and found clear traces of medium-chain chlorinated paraffins (MCCPs) in the surrounding air. The health effects of MCCPs on people are still being studied, though countries are already planning to debate whether thes

Image by Getty / Futurism Cancer Researchers at Johns Hopkins University have discovered that cancer can be detected in the bloodstream a full three years before it's spotted by doctors for an official diagnosis. As detailed in a partially government-funded study published in the journal Cancer Discovery last month, the team found that genetic material being shed by cancer tumors can show up in the bloodstream far earlier than previously thought, paving the way for promising new cancer screeni

Finding high-quality audio can be quite a challenge. Even though wireless earphones are super popular, true audiophiles still prefer wired options for the best sound experience. This is especially true if you’re a musician or a sound engineer, as precision and quality are key. There are differences even then. While you can find many good in-ear monitors, the top-rated ones can often come with a hefty price tag, making them less accessible for the average consumer. That’s the challenge that Kiwi

Neanderthals Spread Across Asia With Surprising Speed—and Now We Know How

Neanderthals and modern humans split from a common ancestor around 500,000 years ago, with Neanderthals leaving Africa for Europe and Asia long before modern humans joined them hundreds of thousands of years later. There, Neanderthals dispersed as far as Spain and Siberia. Our prehistoric cousins likely first reached Asia around 190,000 to 130,000 years ago, with another substantial migration to Central and Eastern Eurasia likely between 120,000 and 60,000 years ago.
