The new Apple Watch Series 6. Photo: Apple

The newest version of the Apple Watch is part of a slew of devices that enable people to monitor their health away from a doctor's office.

Why it matters: The COVID-19 pandemic has accelerated a shift to health monitoring in the home, and companies are rushing to meet the demand.

What's happening: Apple on Tuesday announced its Watch Series 6, with a focus on the device's health capabilities.

  • Already able to detect heart rate, perform an electrocardiogram and track physical activity, the new version can now determine blood oxygen levels through LED clusters and photodiodes.
  • Blood oxygen saturation can be a useful indicator of health, especially during the pandemic. Many severe cases of COVID-19 are marked by alarmingly low blood oxygen levels, even before patients begin experiencing respiratory distress.

Details: The new Apple Watch is one of many remote health monitoring devices being rolled out by tech and health companies alike.

  • The change is being driven by more accurate devices as well as a shift in patients themselves, who increasingly want to optimize wellness, not just avoid illness.
  • "This is a golden moment for distributed medicine and at-home diagnostics," says Siddarth Satish, the CEO of Gauss, a machine-vision startup that developed the first completely at-home COVID-19 test with the biotech company Cellex.

Yes, but: It's still not clear exactly how many of these devices "ultimately fit into a user’s care continuum," notes Erin Brodwin in STAT News.

How mass rapid tests could help curb the pandemic

Vastly expanded approval and distribution of rapid, at-home tests represents a powerful tool in the fight against COVID-19 — and just possibly, the future of disease diagnostics.

Why it matters: Vaccines will take time to arrest the spread of the coronavirus — even without problems around distribution and acceptance. Some experts believe mass rapid testing could quickly identify who is really at risk of spreading COVID-19 and turn around the out-of-control pandemic in the U.S.

Inaugural address: Biden vows to be "a president for all Americans"

Moments after taking the oath of office, President Joe Biden sought to soothe a nation riven by political divisions and a global pandemic, while warning that "we have far to go" to heal the country and defeat a "virus that silently stalks the the country."

Why it matters: From the same steps that a pro-Trump mob launched an assault on Congress two weeks earlier, the new president paid deference to the endurance of American political institutions.

President Biden has delivered his inaugural address at the Capitol, calling for an end to the politics as total war but warning that "we have far to go" to heal the country.

What's next: Biden and Vice President Harris review readiness of military troops, a long-standing tradition to signify the peaceful transfer of power.
