Spacing COVID-19 vaccine doses has epidemiological benefits, but longer-term outcomes depend on immunity robustness

March 9, 2021

Delaying second doses of COVID-19 vaccines should reduce case numbers in the near term. But the longer-term case burden and the potential for evolution of viral “escape” from immunity will depend on the robustness of immune responses generated by natural…

High end of climate sensitivity in new climate models seen as less plausible

March 3, 2021 ・ Morgan Kelly

A recent analysis of the latest generation of climate models — known as a CMIP6 — provides a cautionary tale on interpreting climate simulations as scientists develop more sensitive and sophisticated projections of how the Earth will respond to increasing…

True toll of coronavirus on sub-Saharan Africa may be obscured by tremendous variability in risk factors and surveillance

February 17, 2021 ・ Morgan Kelly

One early feature of reporting on the coronavirus pandemic was the perception that sub-Saharan Africa was largely being spared the skyrocketing infection and death rates that were disrupting nations around the world. While still seemingly mild, the true toll of…

Adherence to health precautions, not climate, the biggest factor driving wintertime COVID-19 outbreaks

February 9, 2021 ・ Morgan Kelly

Wintertime outbreaks of COVID-19 have been largely driven by whether people adhere to control measures such as mask wearing and social distancing, according to a study published Feb. 8 in Nature Communications by Princeton University researchers. Climate and population immunity…

Getting U.S. to net-zero emissions by 2050 will take massive, but affordable, coordination

December 15, 2020 ・ Molly A. Seltzer

With a massive, nationwide effort the United States could reach net-zero emissions of greenhouse gases by 2050 using existing technology and at costs aligned with historical spending on energy, according to a study led by Princeton researchers. The new “Net-Zero…
