Phys.org / How Mycobacterium tuberculosis safeguards itself from foreign DNA
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 ...
Phys.org / Catching a radical in motion with µSR spectroscopy
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 ...
Phys.org / Lysosomes in focus: New study reveals how cells keep them intact
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 ...
Phys.org / Uncovering a secret room that a giant virus creates inside its host amoeba
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 ...
Phys.org / Deciphering symbiotic code: Research unlocks 'secret handshake' between legumes and rhizobia
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 ...
Phys.org / Global study reveals widespread burning of plastic for heating and cooking
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 ...
Phys.org / Dark stars could help solve three pressing puzzles of the high-redshift universe
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 ...
Phys.org / First galaxy-wide wobbling black hole jet discovered in a disk galaxy
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 ...
Phys.org / Scientists solve the mystery of Europe's missing dinosaurs. Spoiler alert! They were never actually missing
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, ...
Phys.org / Repeating fast radio burst shows diverse activity and hints at magnetar origin
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 ...
Phys.org / Replication efforts suggest 'smoking gun' evidence isn't enough to prove quantum computing claims
A group of scientists, including Sergey Frolov, professor of physics at the University of Pittsburgh, and co-authors from Minnesota and Grenoble have undertaken several replication studies centered around topological effects ...
Phys.org / Unexpected oscillation states in magnetic vortices could enable coupling across different physical systems
Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have uncovered previously unobserved oscillation states—so-called Floquet states—in tiny magnetic vortices. Unlike earlier experiments, which required energy-intensive ...
