When it comes to package delivery, early isn't always better. A new study published in Production and Operations Management by researchers at the University of Iowa's Tippie College of Business finds that when a package that's ordered online is delivered earlier than the promised delivery date, the purchaser is apt to give it fewer stars when they leave an online review.
Over the past decades, the diffusion of fake news and other deceptive content on social media platforms has become a heated topic of debate. Some past studies have explored the broad impact of online misinformation, while others have tried to determine whether deceptive content influences voters during political elections.
In materials science, if you can understand the "texture" of a material—how its internal patterns form and shift—you can begin to design how it behaves. That's the focus of the work of Zhenglu Li, assistant professor in the Mork Family Department of Chemical Engineering and Materials Science at USC Viterbi School of Engineering. Li's recently published paper in PNAS, titled "Moiré excitons in generalized Wigner crystals," demonstrates that the way electrons organize themselves inside a material determines how that material responds to light—and how this organization can be engineered.
As he threaded his way through the scrub in Serbia's southern hills, Slobodan Velickovic stopped to inspect the small indigo berries that have made the Balkans a key part of the global gin industry.
By 2085, 36% of species' current habitats on land could be exposed to multiple types of climate-driven extreme events such as heat waves, fire or floods if warming continues to rise into the latter half of the century. The findings are part of a new study published in Nature Ecology & Evolution, authored by an international team of 18 scientists, and led by the Potsdam Institute for Climate Impact Research (PIK).
Flames from raging wildfires in northern Japan were spreading towards the center of a town Friday, with authorities urging more than 2,500 people to evacuate their homes, media reports and the government said.
It was 1972 and Apollo astronauts Harrison "Jack" Schmitt and Eugene Cernan had just stepped onto the moon's surface to begin collecting rock and soil samples.
A massive ice block on the route just above the Mount Everest base camp has forced hundreds of climbers and their local guides to delay their attempt to scale the world's highest peak, officials said Friday.
Ever since humans have embarked on sea voyages, they needed to ensure vessels were waterproof, resistant to salty seawater, and could withstand microorganisms or sea-dwellers like worms. Until the mid-20th century, however, the study of non-wood materials used to build ships was overlooked. Even today, little work has been done on materials used for waterproofing.
The world is undergoing a fundamental change to how money works, and New Zealand should choose its response wisely, an Otago researcher cautions. New University of Otago—Ōtākou Whakaihu Waka research co-authored by Dr. Murat Ungor from the Department of Economics, and his former Masters student Jack Buchan, has been published in the International Journal of Political Economy.
