Posting photos on Facebook for our friends and colleagues might not be a waste of time, as a new study shows our social networks appear to stay intact even after we die.

Why it matters: The study is the first-ever large-scale effort to look at the resilience of a person's social network — online or off — after his or her death. The researchers found increased interactions after someone died of cancer or an accident and less frequent communication after suicide or other causes that have stigma attached to them.

Our thought bubble: How does posting about or tagging someone in a photo translate into support? Can our online relationships be relied on in real life — and does that even matter?

Methodology: Researchers looked at 15,000 anonymized Facebook networks involving 770,000 people to see how resilient human social structures were after the person at the center of them died. They found friends of the deceased not only stayed engaged, they actually increased their ties to each other afterwards, often for years. Close friends interacted 30% more than usual in the month after a mutual friend's death. Their contact waned after that month but even 2 years later they were interacting about 3% more when compared to networks of friends who hadn't suffered a loss.

Interesting detail: 18-24 year olds increased their social network interactions most after a death of a mutual friend or colleague.

Florida smashes single-day record for new coronavirus cases

Data: Covid Tracking Project; Chart: Axios Visuals

Florida reported 15,299 confirmed coronavirus cases on Sunday — a new single-day record for any state, according to its health department.

The big picture: The figure shatters both Florida's previous record of 11,458 new cases and the single-state record of 11,694 set by California last week, according to AP. It also surpasses New York's daily peak of 11,571 new cases in April, and comes just a day after Disney World reopened in Orlando.

Pelosi: Trump is "messing with the health of our children" with push to open schools

House Speaker Nancy Pelosi said on CNN's "State of the Union" Sunday that Education Secretary Betsy DeVos' aggressive push to fully reopen schools this fall is "malfeasance and dereliction of duty," accusing the Trump administration of "messing with the health of our children."

Why it matters: Trump has demanded that schools reopen as part of his efforts to juice the economy by allowing parents to return to work, despite caution from health officials that little is known about how the virus impacts children.
