Explosive New Immune Cell Type Discovered

Explosive new immune cell 'ruptoblasts' discovered in flatworms Researchers identified a glandular cell that literally erupts to kill bacteria and drive tissue rejection. The finding, published in Cell, rewrites immune system understanding and shows cross-species potency. 1

Rotating brain waves discovered that coordinate sensory information Scientists observed spiral-like neural waves traveling across the sensory cortex in mice, forming a circular circuit. The discovery, reported in Science, could reshape how we understand sensory processing. 2

DNA methylation's ancient role is genome defense, study in sea anemone reveals Removing most DNA methylation from sea anemones had little effect on development but unleashed jumping genes. The findings suggest methylation originally evolved to control mobile genetic elements. 3

Quantum mini-universe shows time may emerge from internal change A cloud of 24,000 ultracold atoms, without an external clock, exhibited time emerging from entropy changes. The experiment, published in Physical Review Research, tests the idea that time is not fundamental. 4

JWST finds salty clouds on cold exoplanet GJ504b The famous 'Pink Planet' reveals an atmosphere with exotic chemistry and salt clouds, one of the first direct detections of such clouds in a cold object. The findings mark a step toward studying dim planetary-mass companions. 5

Lunar impact 3.5 billion years ago hints at prolonged bombardment era Tiny baddeleyite grains in a meteorite suggest a massive Moon impact during a previously unrecognized period of intense asteroid strikes. The discovery bolsters evidence that the inner solar system suffered extended bombardment. 6

Stable germanium(I) radical anion isolated for first time Chemists synthesized and fully characterized an alkyl-substituted germanium(I) radical anion, stable at room temperature. The achievement opens new reactivity studies for low-valent group 14 radicals. 7

Unique nickel-pincer enzyme family discovered in aldo-keto reductase superfamily Researchers identified a new family of nickel enzymes that catalyze intermolecular hydride transfer, expanding the known natural nickel biochemistry repertoire. The work appears in Nature Chemistry. 8
