Cakes and drinks sweetener neotame can damage gut wall, scientists find | Food safety

A sweetener used in cakes, soft drinks and chewing gum can seriously damage people’s health by weakening the gut, a new study has found. Consumption of even a small amount of the sweetener neotame can lead to someone starting to suffer irritable bowel syndrome, insulin resistance, and even sepsis, a condition that kills about 40,000 … Read more

How NASA Repaired Voyager 1 From 15 Billion Miles Away

Throughout the five months of troubleshooting, Voyager’s ground team continued to receive signals indicating the spacecraft was still alive. But until Saturday, they lacked insight into specific details about the status of Voyager 1. “It’s pretty much just the way we left it,” Spilker said. “We’re still in the initial phases of analyzing all of … Read more

Holographic displays offer a glimpse into an immersive future

Setting the stage for a new era of immersive displays, researchers are one step closer to mixing the real and virtual worlds in an ordinary pair of eyeglasses using high-definition 3D holographic images, according to a study led by Princeton University researchers. Holographic images have real depth because they are three dimensional, whereas monitors merely … Read more

Making diamonds at ambient pressure

Did you know that 99% of synthetic diamonds are currently produced using high-pressure and high-temperature (HPHT) methods?[2] A prevailing paradigm is that diamonds can only be grown using liquid metal catalysts in the gigapascal pressure range (typically 5-6 GPa, where 1 GPa is about 10,000 atm), and typically within the temperature range of 1300-1600 °C. … Read more
