Chatbots show political bias and steer voters toward some parties, analysis finds

Researchers have developed a technique for detecting and measuring the concentration of many rare-earth elements in plants, without destroying the plant. The technique can be used to optimize "plant mining" efforts, in which plants take up and concentrate these critical materials so that they can be harvested for practical use. The paper is published in the journal Plant Direct.

Improved methods for social and behavioral sciences research could help enhance public trust in science, says a new study that investigated the robustness of data analysis to understand whether it reliably stood the test of time. It did.

Glaciers can reveal vast archives of information about Earth's environmental past, but deciphering the origins of the matter within them can be a challenge. Now, using a novel technique that enables researchers to directly analyze millions of individual particles at once, a new study has revealed that specks of dust trapped in Antarctic ice likely originated from a common source during the last Ice Age, between about 120,000 and 11,500 years ago.
