Source: National Center for Immunization and Respiratory Diseases; CDC Continues to Track the Growth of JN.1 December 22, 2023
"JN.1 continues to increase in proportion. CDC has been tracking JN.1 for months, since it first split from its parent, BA.2.86. JN.1 is similar to BA.2.86 but has an additional mutation (L455S) in the spike protein. JN.1 continues to cause an increasing share of infections and is now the most widely circulating variant in the United States. For the two weeks ending on December 23, 2023, JN.1 is expected to account for 39-50% of all SARS-CoV-2 variants. That’s an increase from the projected prevalence two weeks ago of 15-29%. We’re also seeing an increasing share of infections caused by JN.1 in travelers, wastewater, and most regions around the globe. Help reduce the spread of COVID-19. Improving your indoor air is one of the best ways to prevent spread. This can be as simple as using a portable air cleaner or opening windows (for those with pleasant winter weather). And if your home thermostat offers a FAN option, turn it from AUTO to ON when you have visitors to keep air running continuously. Learn more about other ways to help reduce spread, including testing for COVID-19, wearing masks, and increasing space and distancing."

Justice Department Files Statement of Interest in Case on Right to Travel to Access Legal Abortions
Attorney General Merrick B. Garland. “As I said the day Dobbs was decided, bedrock constitutional principles dictate that women who reside in states that have banned access to comprehensive reproductive care must remain free to seek that care in states where it is legal,” said Attorney General Merrick B. Garland. “This filing demonstrates the Justice Department’s commitment to defending the constitutional right to travel and to protecting reproductive freedom under federal law.” more »
Crosswalks and Pedestrian Safety: What You Need to Know From Recent Research
In recent months, news organizations have covered crosswalk construction or changes to existing crosswalks, including new, decorative pavers in Slidell, Louisiana, proposed infrastructure changes aimed at improving pedestrian safety in Phoenix, and decorative, themed crosswalks, such as rainbow crosswalks painted in towns across the country for Pride month. Such stories call attention to the dangers of pedestrians and vehicles sharing roadways -- and the rising rate of pedestrian deaths nationwide. The Governors Highway Safety Association estimates at least 7,508 pedestrians were killed as a result of crashes on U.S. roadways in 2022. more »
We've Pumped So Much Groundwater That We've Nudged The Earth's Spin
“Observing changes in Earth’s rotational pole is useful for understanding continent-scale water storage variations,” said Ki-Weon Seo, a geophysicist at Seoul National University who led the study. Seo said. “Polar motion data are available from as early as the late 19th century. So, we can potentially use those data to understand continental water storage variations during the last 100 years. Were there any hydrological regime changes resulting from the warming climate? Polar motion could hold the answer.” “I’m very glad to find the unexplained cause of the rotation pole drift,” Seo said. “On the other hand, as a resident of Earth and a father, I’m concerned and surprised to see that pumping groundwater is another source of sea-level rise.”
