But building a network out of these fragile threads is no easy feat. Fiber optic cables, the workhorses of modern communication, introduce signal loss and memory decoherence. Quantum information is ...

With C30 and C31 sterols now validated as biomarkers of ancient sponges, the team plans to expand their search to other regions and rock formations. Their goal: to pinpoint when, exactly, the first ...

In the heart of Egypt’s ancient religious capital, Thebes, a team of international researchers has peeled back the layers of time to reveal the hidden story of Karnak Temple, on ...

A new 3-D-printed aluminum alloy is stronger than traditional aluminum, due to a key recipe that, when printed, produces aluminum (illustrated in brown) with nanometer scale precipitates (in light ...

Dr. David Bacon, now at University College London, helped classify the two types of dark excitons: momentum-dark and spin-dark. Momentum-dark excitons arise when electrons scatter into different ...

Red-emitting dyes offer more explicit images for deep-tissue imaging, but they’ve long been hindered by poor brightness and instability. Most red dyes have low quantum yields; only about 1% of the ...

In a cosmic twist worthy of science fiction, astronomers have spotted the most distant and powerful “odd radio circle” (ORC) ever recorded, a ghostly, double-ringed structure glowing in radio waves ...

A new study, published in Nature Photonics and led by Politecnico di Milano, reveals a previously neglected but essential aspect: the contribution of virtual charges, charge carriers that exist only ...

“Thanks to our results, we know that the proto-Earth was initially a dry rocky planet,” says Kruttasch. “It can therefore be assumed that it was only the collision with Theia that brought volatile ...
