Inverted perovskite solar cells offer strong potential for scalable, low-cost solar power, but a hidden interface inside the device has limited their performance and durability. Researchers have now introduced crystal-solvate nanoseeds that guide ...

For the first time ever, scientists have uncovered a vast field of tektites in Brazil -- mysterious glassy fragments forged when a powerful extraterrestrial object slammed into Earth about 6.3 million years ago. Named "geraisites" after Minas Gerais, ...

Scientists in Brazil have transformed cocoa waste into a functional chocolate-infused honey packed with antioxidants and natural stimulants. Using ultrasound waves, they enhanced honey's ability to pull beneficial compounds from cocoa shells--no ...

Scientists at Rice University have produced the first full, dye-free molecular atlas of an Alzheimer's brain. By combining laser-based imaging with machine learning, they uncovered chemical changes that spread unevenly across the brain and extend ...

That photogenic cup of bubble tea may come with hidden downsides. Tapioca pearls made from cassava can absorb heavy metals like lead, and in large amounts they may slow digestion or even cause blockages. The drink is often loaded with sugar- ...

Scientists at Oregon State University have engineered a powerful new nanomaterial that zeroes in on cancer cells and destroys them from the inside out. Designed to exploit cancer's unique chemistry--its acidity and high hydrogen peroxide levels--the ...

Scientists have pulled off a feat long considered out of reach: getting light to mimic the famous quantum Hall effect. In their experiment, photons drift sideways in perfectly defined, quantized steps--just like electrons do in powerful magnetic ...

Astronomers have long known the universe is expanding--but exactly how fast remains one of the biggest mysteries in cosmology. Different techniques for measuring the Hubble constant stubbornly disagree, creating the so-called "Hubble tension." Now .. ...

Jupiter's icy moons may have been seeded with the chemical ingredients for life from the very beginning. An international team of scientists modeled how complex organic molecules--essential building blocks for biology--could have formed in the ...

Struggling to fall asleep and stopping breathing at night may be a far riskier combo than previously thought. In a study of nearly a million veterans, researchers found that having both insomnia and sleep apnea dramatically raises the risk of ...
