779 Quantum ghost imaging works using only sunlight in stunning new experiment

ScienceDaily
ScienceDaily · 05/17/2026 22:30 EDT

Scientists have achieved something that once sounded almost impossible: using ordinary sunlight to create quantum-linked photon pairs, a phenomenon normally dependent on precise laboratory lasers. By building a sun-tracking system that funnels sunlight through optical fiber into a special crystal, researchers generated strongly correlated photons capable of performing “ghost imaging,” where images are reconstructed indirectly through quantum correlations. Remarkably, the sunlight-powered setup produced imag

Heavy marijuana smoking may raise the risk of lung cancer and several head and neck cancers, according to growing research, but many important questions remain unanswered. Scientists are still trying to determine how much marijuana use is enough to significantly increase cancer risk. Edibles have not been linked to lung cancer so far, while the long-term effects of vaping marijuana and secondhand marijuana smoke are still being investigated. Read more

A new study found that dietary fiber can determine whether beneficial intestinal worms help reduce inflammation or become essentially inactive. With plenty of fiber, the worms remained healthy and supported an anti-inflammatory response, while a low-fiber diet pushed them into a hibernation-like state that eliminated those benefits. Researchers also found that fiber-rich diets promoted healthier gut bacteria, whereas Western-style diets reduced microbial diversity and encouraged less desirable microbes. Read more

Many of the body's biggest flaws are the result of evolution building on old designs instead of starting over. Our spine, eyes, teeth, pelvis, and even certain nerves all reveal compromises that worked well enough for survival but still leave us prone to pain, injury, and disease. Structures like the appendix and ear muscles also remain because they were never harmful enough for evolution to eliminate. Together, these features tell... Read more
