Spike D614 Reversions Detected in Delta and Omicron BA.2 Variants
Researchers from the University of Tsukuba and the Institute of Science Tokyo identified nonrandom reversions of the SARS‑CoV‑2 spike protein from the dominant G614 back to the ancestral D614. The reversions are concentrated in delta and omicron BA.2 lineages and show distinct temporal spikes and geographic clustering.
Astrophysicists Alberto Magaraggia and Nico Cappelluti of the University of Miami report that LIGO captured a gravitational‑wave signal (S251112cm) consistent with a sub‑solar mass black hole, the first possible detection of a primordial black hole. The finding could provide direct evidence for a long‑theorized dark‑matter component.
