Study finds that heavy metal-contaminated leafy greens turn purple Some might say you look a little green when you are sick. Leafy greens actually turn purple—although not obvious to the human eye, it can be seen through advanced hyperspectral imaging (different than purple varieties of some vegetables). Purdue researchers discovered this color change in kale and basil stressed by cadmium, a heavy metal toxic to human and animal health.
When graphene speaks, scientists can now listen It may be true that seeing is believing, but sometimes hearing can be better.
Researchers set their sights on chalcogenide nanostructured displays One of the key components behind next-generation high resolution video displays will be optical nanoantennas. These devices use nanotechnology to mix and interfere with light beams to produce color and even holograms.
The role of ribosomes in age-related diseases Aging leads to a decline in cellular fitness and loss of optimal protein function. Many age-related ailments, including Alzheimer's and Parkinson's diseases, are caused by protein aggregation, a result of errors in protein folding. Yet, the mechanisms underlying how aging causes proteins to aggregate has largely remained a black box. In new research published Jan. 19 in Nature, researchers at Stanford University have traced this problem to age-dependent impairment of the machinery that produces new proteins.
Researchers use electrically responsive fluid to make eye-like adaptive lens Researchers have developed an adaptive liquid lens based on a new electrically responsive fluid called dibutyl adipate (DBA) that changes focal length when a voltage is applied. The lens is lightweight, compact and simple to fabricate, which makes it ideal for mobile phone cameras, endoscopes, eyeglasses and machine vision applications.
A volcanic eruption in 2020 led to hours-long thunderstorm A study conducted by scientists at the U.S. Geological Survey, the National Oceanic and Atmospheric Administration, and Vaisala Inc., published yesterday in the Geological Society of America's journal Geology, discusses how advances in global lightning detection have provided novel ways to characterize explosive volcanism. Lead author Alexa Van Eaton says, "It's the perfect storm—explosive eruptions can create lightning that is detected around the world."
Untangling the roots of plant genomes: Supporting a 'moonshot' for botany Research featured this month in Proceedings of the National Academy of Sciences highlights the progress of plant genomics and includes a roadmap for the enormous task of sequencing the genomes of plants worldwide.
