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.
Researchers evaluated multiple chronic restraint stress (CRS) protocols in male mice, revealing that short, high‑intensity sessions (6 hours for three days) produce persistent avoidance and repetitive behaviors, while extended low‑intensity exposure (2 hours for ten‑plus days) leads to progressive deficits in reward‑seeking and coping. The ten‑day threshold marks a behavioral shift, and both ketamine and paroxetine demonstrated predictive validity by reversing distinct phenotypes. The study establishes standardized CRS regimens that capture key features of anxiety‑ and depression‑related disorders, enhancing translational relevance for preclinical neuroscience.
Researchers recorded dorsal (dHPC) and ventral (vHPC) hippocampal neurons in rats performing rewarded and aversive runs, then examined sleep periods. They found that neural assemblies from both regions reactivate strongly during early post‑sleep, with reactivation rates returning to baseline later....
