Monitoring marine life helps scientists track ecosystem health, improve conservation and manage fisheries. A promising approach is environmental DNA (eDNA), which refers to trace genetic material naturally released into the water by organisms, such as skin cells, mucus and excreta.
A new recycling technique could help tackle a major challenge: breaking down some of the toughest plastics without generating large amounts of waste.
A team of researchers from University of Toronto Engineering has created a new type of dye-sensitized nanoparticle that can detect target chemicals at very low concentrations while also distinguishing between molecules with very similar shapes.
Have you ever wondered what Earth observation satellites see when they look down at the deep ocean or a dense tropical forest during the dead of night? The answer, for the most part, is nothing. Standard optical sensors require a steady stream of light to function, and in these photon-limited regions, they hit a hard physical boundary. But what if we could rewrite the rules of optical imaging? By borrowing techniques from quantum photonics, we can push beyond these classical limits and unlock a fundamentally new way to observe the darkest and most hidden environments on our planet.
Artificial intelligence is transforming how information is generated, processed and stored, but its rapid expansion is also driving unprecedented demand for computing power and electricity. Developing hardware that can process information more efficiently is therefore becoming one of the major technological challenges of the AI era.
Picture yourself in a manufactured colony that orbits between Earth and the moon. It might sound like science fiction, but it's part of a 2019 presentation made by Jeff Bezos, founder of the space technology company Blue Origin, to an audience of journalists, space industry executives and policymakers.
In a study of monk parakeets, researchers at the University of Cincinnati and Duke University found that sex has little to no impact on who initiates fights, who is targeted or who rises in the dominance hierarchy.
With the rise in popularity of the digital assets known as cryptocurrencies over the last decade, the idea of a decentralized financial system that operates outside traditional markets is gaining mainstream appeal. A new analysis from a Penn State researcher, however, suggests that traditional and decentralized markets are more connected than they might seem.
Emotional mechanisms are frequently used to inspire good environmental behavior. But how effective are they at inspiring actual sustainable change? Perhaps not as much as previously believed, according to a new study that challenged participants to put their money where their mouths are.
The Kinsey Institute released new data from its annual Singles in America survey, the nation's most comprehensive and longest-running annual study of single adults. Now in its 15th edition, Singles in America has surveyed more than 80,000 people across the United States, creating one of the richest data sets available for understanding shifting relationship patterns, population demographics and social trends.
