Onboarding support helps merchants adopt digital payment methods‎

Change can be hard—especially when you're used to receiving change. Switching from cash-based to digital payment methods can be a difficult sell, particularly in developing economies, poorer neighborhoods and among older people who have gotten used to cash. But digital payments have certain advantages for both businesses and consumers, and a Cornell-led research team explored ways to spur adoption of modern payment technology.

Benzene reaction may explain how DNA and RNA building blocks formed on early Earth‎

Caltech researchers have identified a novel chemical reaction that could explain the formation of the building blocks of DNA and RNA, the molecules that encode all of life's functions. The work is an important step toward understanding how life may have emerged on Earth and potentially elsewhere in the universe, showing the straightforward and efficient pathways through which simple molecules can give rise to complex biological precursors.

Why Arctic sea ice loss could reshape the Gulf Stream's future‎

The warm Gulf Stream is maintained by coldness. The Barents Sea is a cooling machine. To predict how ocean currents in the Atlantic Ocean may develop, one needs to know what drives them. The hunt for driving forces has led researchers to follow the warm water from the Gulf Stream as far north as it gets.

Being your own boss doesn't always pay off: What 30 years of data reveal‎

More than 2.6 million Canadians work for themselves, and according to an annual RBC poll conducted in 2025, 59% of Canadians aspire to own a business—the highest level since 2017.

Earthquakes can be destructive for distant cities built on top of basins—now we know why‎

Sedimentary basins—depressions in Earth's crust caused by tectonic activity—tend to be flat and are favored places to build cities. But during earthquakes, they can become natural resonance chambers.

Deep-sea crust uncovers steady plutonium rain from ancient kilonova debris‎

Debris is still raining down on Earth more than 100 million years after the giant cosmic explosion that created it. A study published this week in Nature Astronomy by an international team reached this conclusion using measurements of rare isotopes within a slow-growing ferromanganese crust recovered from the depths of the Pacific Ocean.

A waltz over evolutionary timescales: Why it's so hard for animals to invent a new mating dance‎

"Love makes fools of all of us," wrote 19th-century novelist William Makepeace Thackeray. A moment spent watching the pigeons at your local park suggests he was right: males with puffed-up, shimmering necks hop, pirouette, coo, and bow to capture the attention of unimpressed females.

Do shark culls keep people safe in the ocean? Here's what the science says‎

A young mother remains in hospital after being bitten by a shark at Coogee Beach in Sydney on Saturday morning. Leah Stewart, 35, was swimming about 30 meters (33 yards) offshore when the shark—believed to be a 3- to 4-meter (10- to 13-foot) great white shark—struck.

Redefined conformity model beats averaging in five real-world tests of opinion dynamics‎

Imagine you poll your friends on how many minutes per pound to roast a turkey. Five respond with 15 minutes; one answers 33 minutes. The most popular model of conformity, the French-Harary-DeGroot model (or more commonly, DeGroot model), assumes that you would carefully weigh all six recommendations, calculating a cooking time of 18 minutes per pound. But under a model of conformity previously published by SFI Complexity Postdoctoral Fellow Kaleda Denton and colleagues, you would disregard the outlier and move ahead with 15.

As AI plays a bigger role in relationships, true intimacy is getting lost‎

The CEO of dating app Hinge recently suggested that generation Z, "struggling to have the confidence to put themselves out there," needs AI to help them find love. Apparently, without AI tools, younger people will struggle to express who they really are.
