In collaboration with Ohio State University and the University of Minnesota, scientists have built a new map of Antarctica using high resolution satellite images to show the continent in "stunning detail," USA Today reports.

Why it matters, per Axios Science Editor Andrew Freedman: In order to determine the stability of Antarctica's massive ice sheets, particularly the West Antarctic Ice Sheet that has been losing mass, scientists need accurate maps of the ground the ice is resting on. Improvements in mapping could enable researchers to narrow the range of uncertainty regarding future sea level rise from Antarctic ice melt.

Healthy volunteers who took Moderna's coronavirus vaccine candidate appeared to generate an immune system response to the virus, and there were "no trial-limiting safety concerns," according to a new study published in the New England Journal of Medicine.

Why it matters: The phase one trial is still small and does not definitively determine how effective the vaccine is. But Anthony Fauci of the National Institutes of Health, which is running the trial, told the Wall Street Journal that these data make it "pretty clear that this vaccine is capable of inducing quite good [levels] of neutralizing antibodies."

President Trump announced Tuesday that he has signed a new bill sanctioning Chinese officials in response to Beijing's national security law for Hong Kong, which dramatically curbs the city's political freedoms. He also signed an executive order ending preferential treatment for Hong Kong.

Why it matters: The bill, which will sanction both Chinese individuals interfering in Hong Kong's affairs and the banks that support them, has broad bipartisan support in Congress. Its passage into law is the latest escalation by the Trump administration against the Chinese Communist Party's efforts to strip Hong Kong of its autonomy.

Fauci on who to trust amid coronavirus: "Stick with respected medical authorities"

When asked on Tuesday who the public can trust during the coronavirus pandemic, Anthony Fauci said that people "can trust respected medical authorities ... who have a track record of giving information and policy and recommendations based on scientific evidence and good data."

Why it matters: Fauci's comments come as the White House tries to sideline the National Institute of Allergy and Infectious Diseases director in the middle of the pandemic. Multiple media outlets received a statement on Monday from an unnamed White House official that listed each time Fauci was "wrong on things" in COVID-19's early days.
