Cobalt Robotics, a developer of robotic security guards for office buildings, raised $13 million in Series A funding led by Sequoia Capital.

Why it's a big deal: This might be the first step toward replacing not only human security guards, but also certain types of facilities managers (its detection skills include water leaks and spills).

Last year a Wired reporter "spent the night" with a Cobalt robot that was guarding the offices at Yelp.

Bottom line, per CNBC: "The robot could help companies save money on human security guards: businesses spent almost $68 billion on physical security in 2016, according to industry research by Stratistics MRC. That number is expected to surpass $125 billion by 2022, with a hefty chunk of spending going to human security guards indoors."

The U.S. Supreme Court ruled late Wednesday that restrictions previously imposed on New York places of worship by Gov. Andrew Cuomo (D) during the coronavirus pandemic violated the First Amendment.

Why it matters: The decision in a 5-4 vote heralds the first significant action by the new President Trump-appointed conservative Justice Amy Coney Barrett, who cast the deciding vote in favor of the Catholic Church and Orthodox Jewish synagogues.

The acting administrator of the United States Agency for International Development informed senior staff Wednesday he has tested positive for coronavirus, two sources familiar with the call tell Axios.

Why it matters: John Barsa, who staffers say rarely wears a mask in their office, is the latest in a series of senior administration officials to contract the virus. His positive diagnosis comes amid broader turmoil at the agency following the election.

COVID-19 shows a bright future for vaccines

Promising results from COVID-19 vaccine trials offer hope not just that the pandemic could be ended sooner than expected, but that medicine itself may have a powerful new weapon.

Why it matters: Vaccines are, in the words of one expert, "the single most life-saving innovation ever," but progress had slowed in recent years. New gene-based technology that sped the arrival of the COVID vaccine will boost the overall field, and could even extend to mass killers like cancer.
