Phys.org / Organic molecule with ultranarrow emission spectrum could lead to better LEDs
Over the past several decades, light sources have gradually transitioned to light-emitting diodes, or LEDs, and inorganic LEDs are now used across a wide range of applications. In parallel, organic LEDs, or OLEDs, have become ...
Phys.org / First leather bag made from T-Rex cells fails to sell at Paris auction
A leather bag made from Tyrannosaurus rex cells failed to sell Thursday, the Paris auction house Drouot said, commenting that bids were well below expectations.
Phys.org / Light echoes reveal possible dark matter buildup around supermassive black holes
We may not know what dark matter is, but we keep getting whiffs of it. "We are reaching a point where the observational evidence for dark matter is simply undeniable," said Mayank Sharma, a Virginia Tech graduate student ...
Phys.org / Cosmic dawn fuel discovery unlocks early galaxy growth secrets
Astronomers have discovered a huge reservoir of cold molecular gas, the direct fuel for star formation, in REBELS-25, a massive, star-forming galaxy. The team, led from Leiden University, focused on REBELS-25, seen when the ...
Phys.org / Physicists introduce phase contrast to electron microscopy, delivering sharper images of our body's tiniest proteins
Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which garnered a Nobel Prize in 1953, brought into clear view structures inside cells that had previously ...
Phys.org / Prescribed fires can cut smoke pollution for years, miles beyond burn areas
A new study finds that burning 500,000 acres (202,000 hectares) of California conifer forests each year with prescribed fire could cut deadly pollution from wildfire smoke by roughly 10% over a decade.
Phys.org / Quantum friction causes light to slow down nanoworld movements
A research team in Bochum, Germany has unexpectedly found that light can slow down movements in the nanoworld. This is due to quantum friction, a phenomenon that has been poorly understood until now. The findings are published ...
Phys.org / A new kind of entanglement helps quantum sensors tune out noise
In a quest to build the most accurate quantum sensors in the world, scientists are constantly improving their performance, making them more precise, more stable and more reliable. But eventually, physical constraints will ...
Phys.org / AI fast-forwards molecular simulations by 10,000-fold
A new AI model has become so good at predicting how molecules evolve over time that, in the future, it could speed up the costly and time-consuming process of testing new drugs. In the long term, this technology could facilitate ...
Dialog / Binary asteroids' puzzling configurations may link to multi-satellite history
Binary asteroid systems are widespread throughout our inner solar system. For decades, the standard paradigm held that many of them form when a rapidly spinning primary asteroid casts off material, which then reaccumulates ...
Phys.org / Why cells started sticking together could help explain how animals first evolved
A recent study by Ruibao Li and Jennah Dharamshi published in Nature may help us understand the beginnings of animal evolution billions of years ago. These findings are the result of a collaboration among researchers at Indiana ...
Phys.org / Forest gaps and deadwood boost bird and bat diversity in woodlands
Disorder brings more life to the forest: Birds and bats react to this in different ways. This is shown by a new study from the University of Würzburg's Biocenter.
