Emissions tied to the international trade of agricultural goods are rising

Earth system scientists at the University of California, Irvine and other institutions have drawn the clearest line yet connecting consumers of agricultural produce in wealthier countries in Asia, Europe and North America with a growth in greenhouse gas emissions in less-developed nations, mostly in the Southern Hemisphere.

Does presenting credibility labels of journalistic sources affect news consumption? New study finds limited effects

Labeling the credibility of information sources does not shift the consumption of news away from low-quality sources or reduce belief in widely circulated inaccurate claims among average internet users, but providing an indicator of sources' quality may improve the news diet quality of the heaviest consumers of misinformation, shows a new study by New York University's Center for Social Media and...

Remote learning likely widened racial, economic achievement gap

A new report on pandemic learning loss found that high-poverty schools both spent more weeks in remote instruction during 2020–21 and suffered large losses in achievement when they did so. Districts that remained largely in-person, however, lost relatively little ground. Experts predict the results will foreshadow a widening in measures of the nation's racial and economic achievement gap.

'The Rock' diamond dazzles in Geneva

The biggest white diamond ever to be sold at auction, dubbed "The Rock," will go under the hammer in Geneva on Wednesday and could fetch up to $30 million—or more.

Scientists develop powerful family of 2D materials

A team from the Tulane University School of Science and Engineering has developed a new family of two-dimensional materials that researchers say has promising applications, including in advanced electronics and high-capacity batteries.

Biomolecular insights into protein-insolubility-related disease

Amyloidosis is the collective name for a group of diseases characterized by the deposition of amyloids—insoluble proteins that form due to the misfolding and aggregation of soluble proteins—outside of cells. Such depositions lead to cellular dysfunctions, and take place in patients with Alzheimer's disease, Parkinson's disease and dementia. In the disease called hereditary (variant)...

What ancient pollen tells us about future climate change

Around 56 million years ago, Earth's climate underwent a major climatic transition. A huge release of carbon into the ocean and atmosphere raised atmospheric carbon dioxide (CO2) concentrations—which meant temperatures going up by 5 to 8°C and rising sea levels.

Business intelligence acts as a precursor to strategy

Business Intelligence (BI) and analytics play a key role in strategy work. However, business intelligence is not just a data mass that supplements strategy or a self-evident prop, but, together with the predictions generated by new algorithms and computational models, it can even act as a driving force or "prime mover" in strategy formation, according to Yassine Talaoui's doctoral thesis at the...

First rays of sunlight for balloon-borne solar observatory Sunrise III

Approximately a month before it begins its research flight in the stratosphere, the balloon-borne solar observatory Sunrise III has looked at the Sun for the first time from its launch site at the Arctic Circle. In June, Sunrise III will take off from Esrange Space Center, the Swedish Space Agency's (SSC) balloon and rocket base in Kiruna (Sweden), and will climb to an altitude of about 35...
