Certifying third-party repairs retains customers, signals utility left in goods
Certifying a third-party repair service can help companies retain customers by signaling that there's value, or "unused utility," left in broken products, according to a team led by Penn State researchers. The researchers, who were raised by parents and grandparents with what
The real Moana story: Why the Polynesians suddenly sailed east
Major drought forced people to migrate across the Pacific beyond Samoa and Tonga and toward the Americas, scientists have discovered. With the new live-action "Moana" film hitting cinemas, a team of geographers and climate scientists from the Universities of Southampton and
Observing oscillations, flares and tornados on the sun
For six and a half days in July 2024, the balloon-borne solar observatory Sunrise III kept its gaze fixed on the sun. The stratospheric flight, which stretched from the northernmost tip of Sweden to Canada's Northwest Territories, yielded a treasure trove of data exceeding 200

New neutron method reveals inner architecture of drug delivery particles
Modern medicine increasingly relies on targeted drug delivery—a process during which tiny particles (nanoparticles) transport drugs to specific parts of the body. To ensure these treatments are safe and effective, scientists need to understand exactly how these nanoparticles
A 'smart ruler' could help swarms of space telescopes image exoplanets
We've talked plenty of times here about the infeasibility of launching a mirror big enough to directly image exoplanets using current rocket fairings—at least as long as we're not sending them 500-plus AU away to a gravitational lensing point. We've also talked at length about
Palm oil shows promise as greener processing aid for natural rubber composites
Natural rubber is widely used in tires, transport, construction, health care and industrial products because of its elasticity, resilience and durability. To improve performance, rubber manufacturers often add silica fillers and processing oils. These oils help reduce
Making scientific knowledge free for all

Earth's deep memory is thawing with the Arctic permafrost, degrading records of our ancient world
Permafrost usually hits the news as a hazard, a planetary risk. When this ice-rich ground thaws, it damages roads and building foundations. It drains lakes and tips trees into drunken forests. It releases greenhouse gases that have been locked in carbon-rich soils for thousands

The secret life of roots: How plants fight back against salty soils
To people, salt is a kitchen staple. But to crops, too much of it can be devastating. Across coastal regions and irrigated agricultural land, salt is accumulating in soils, making it harder for plants to absorb water and reducing harvests. Scientists estimate that around half

Honesty may be more efficient than incentives in organizations, new research finds
For decades, economic theory has often treated people as if they will do the right thing in organizations only when incentives, such as performance pay, force them to. But does this miss the fact that many people also care about honesty?
Heat waves push tropical forests past photosynthesis limits across 57 million hectares
As heat waves continue one after another, we are feeling their effects on our own bodies: It becomes harder for us to function normally. Trees also have their limits when temperatures are too high. Above a certain critical temperature, photosynthesis, the process by which
