How longer exciton lifetimes could ease efficiency trade-off in organic solar cells
How longer exciton lifetimes could ease efficiency trade-off in organic solar cells
Although the efficiency of organic solar cells has now risen to more than 20%, there are physical limits that make it difficult to further increase their performance. A research team from Linköping University in Sweden, the University of Potsdam, the Paul-Drude-Institut in Berlin

Mathematical modeling helps advance use of magnetic particles in targeted drug-delivery sy
A Florida State University computational scientist is paving the way for future medical breakthroughs by developing mathematical models and simulations to predict the behavior of a unique drug-delivery method, which aims to deploy treatments directly to targeted sites in the body
Drifting tuna gear creates risks for wildlife in protected marine areas
An international study co-authored by a University of Hawaiʻi at Mānoa researcher has found that drifting devices used by the global tuna fishing industry are entering marine protected areas around the world, creating potential risks for wildlife and sensitive ocean habitats.

'Fingerprints' of black hole's event horizon detected for first time
Scientists have detected the "fingerprints" of a black hole's event horizon—the boundary from which nothing can escape—for the first time, according to research published Wednesday.
'Super-puff' planets lighter than candy floss discovered by international team
'Super-puff' planets lighter than candy floss discovered by international team
An international collaboration has discovered two of the lowest-density giant planets ever detected: rare "super-puff" planets with densities lower than candy floss. The study—led by the University of Oxford, in collaboration with Université Côte d'Azur/Observatoire de la Côte d'
Pesticide widespread in blood of French Indies adults: Study
Eight in 10 adults in the French West Indies have a toxic pesticide in their blood decades after banana growers stopped using it, a study said Wednesday.
Did gravitational tides cause Earth's extinctions?
Did gravitational tides cause Earth's extinctions?
Life on Earth took a long evolutionary journey that eventually created us, the purportedly intelligent species that dominates the planet. But there was no grand plan or design, only happenstance, nature and luck. Life on Earth suffered multiple extinctions, but got up, dusted its
Laser experiments push helium to record shock pressures
Deep inside gas giants like Jupiter and Saturn, hydrogen and helium coexist under pressures millions of times greater than Earth's atmosphere. Under those conditions, helium may separate from hydrogen and influence a planet's internal heat flow, structure and magnetic field. Unde
Shorter front-leg strides can be an early warning sign of dementia in senior dogs
Scientists have shown that the stride length of the front legs (but not the hind legs) of senior and geriatric dogs decreases as their cognitive performance worsens. In contrast, chronological age itself was a poor predictor of stride length. A similar reduction in step length ha
A NASA satellite caught a giant tsunami doing something no one expected
A NASA satellite caught a giant tsunami doing something no one expected
A Pacific-wide tsunami triggered by a magnitude 8.8 Kamchatka earthquake gave scientists their first detailed satellite view of a major tsunami in motion. The observations revealed unexpected wave behavior and helped uncover a larger earthquake rupture than earlier models predict

Precious drops: Spray helps crop farmers facing declining rainfall
A spray made from a biodegradable polymer capable of capturing and redirecting water to crop seeds could be the key to drought-proofing Western Australian farms.
Designer proteins unlock near-infrared and SWIR glow for deeper tissue imaging
Researchers at the National Center for Tumor Diseases (NCT/UCC) in Dresden, including Oliver Bruns and Dr. Bernardo Arús, are participating in an international study that has, for the first time, developed novel proteins for near-infrared (NIR) and short-wave infrared imaging (SW
