Glassy materials are everywhere, with applications far exceeding windowpanes and drinking glasses. They range from bioactive glasses for bone repair and amorphous pharmaceuticals that boost drug solubility to ultra-pure silica ...

Astronomers have long puzzled over how some massive galaxies stop forming stars and remain dormant for billions of years—even when they still contain gas that could, in principle, fuel new stars.

Researchers at the Indian Institute of Science (IISc), with collaborators from the Institute of Mathematical Sciences (IMSc), have discovered how a key protein in the tuberculosis bacterium helps protect it from the influence ...

Using muon spin rotation spectroscopy, researchers from Japan and Canada have successfully captured the rapid conversion of an imidoyl radical into a quinoxalinyl radical occurring within nanoseconds. The technique enabled ...

When the cell's recycling stations, the lysosomes, start leaking, it can become dangerous. Toxic waste risks spreading and damaging the cell. Now, researchers at Umeå University have revealed the molecular sensors that detect ...

A virus relies on the host's translation machinery to replicate itself and become infectious. Translation efficiency partially depends on the usage of a codon, or sequence of three nucleotides, that matches the cellular pool ...

In a study published in Science, researchers have resolved, for the first time, the high-resolution crystal structure of the complex formed between the NodD protein of pea rhizobia and a flavonoid compound (hesperetin). They ...

A new Curtin University-led study has shed new light on the widespread number of households in developing countries burning plastic as an everyday energy source, uncovering serious international health, social equality and ...

A recent study provides answers to three seemingly disparate yet pressing cosmic dawn puzzles. Specifically, the authors show how dark stars could help explain the unexpected discovery of "blue monster" galaxies, the numerous ...

Astronomers using W. M. Keck Observatory on Maunakea, Hawaiʻi Island have uncovered the largest and most extended stream of super-heated gas ever observed flowing from a nearby galaxy, providing the clearest evidence yet ...

Ceratopsians were horned, beaked dinosaurs that once stomped their way all over North America and Asia during the Late Cretaceous period, about 80 million years ago. Their abundance in the fossil records of these continents, ...

Using the upgraded Giant Metrewave Radio Telescope (uGMRT), Indian astronomers have performed multi-frequency observations of a repeating fast radio burst designated FRB 20201124A. Results of these observations shed more ...
