To enter our cells, the Covid-19 virus fuses its surrounding membrane with the membrane of the target cell.

Cancer is the second leading cause of death in the United States, according to a 2026 Cancer Research Institute report. Cancer biologists are keenly aware of this statistic, as it drives them to innovations that revolutionize cancer care-innovations like immunotherapy.

ZEISS today introduced ZEISS VersaXRM 5 Insight, a hybrid 3D X-ray microscope designed to help researchers and engineers understand samples faster.

Researchers found that mice later classified as resilient showed stronger coordination between neuronal OFF-periods and slow-wave activity in the prelimbic cortex even before social stress. After social defeat, resilient mice also showed a distinct reorganization of neuronal silence during NREM sleep, linking local sleep dynamics with behavioral resilience.

Medical assistance can help women suffering from severe nausea and vomiting during pregnancy, but insufficient recognition of Hyperemesis gravidarum (HG) means that many are not getting the help they need to overcome this severe and debilitating form of morning sickness.
