Those with increasing ...
New research from UC San Francisco found that senescent cells promote normal repair and healing in damaged tissues, contradicting the long-held view that they are purely detrimental. The study used senolytics to kill senescent cells and found that injuries healed more slowly. However, the researchers also discovered that senescent cell...
A 14% decrease in live births was observed in Europe nine months after the start of the COVID-19 pandemic and first lockdowns. The decline may be linked to lockdowns rather than COVID-19 infection, with countries experiencing longer lockdowns having lower birth rates.
