The museum faced a docent dilemma.

When Ellen Owens, director of learning and public engagement at the Penn Museum, looked at her pool of docents, she saw a wonderful — and aging — group of largely white people. Docents explain exhibits to visitors and show them around the galleries. Owens thought that having docents from a range of ages and backgrounds might be a good way to connect with more diverse communities who might not otherwise be drawn to the Penn Museum.

Virginia's Democratic governor seemed poised to make broad changes to his state's gun control laws, but was dealt a stinging blow by his own party Monday when a state Senate committee blocked a bill that would have, among other things, banned sales of assault weapons.

Four Democrats on Virginia's Senate Judiciary Committee broke ranks with their party handing the Republican minority a victory in tabling the bill for the remainder of the year. It also sent the measure to the state's Crime Commission for further review.

Fourteen U.S. passengers evacuated from a cruise ship in Japan and flown to military bases in California and Texas have tested positive for the new coronavirus, U.S. officials confirm.

Earlier, on Sunday, U.S. officials announced that 44 people from the Diamond Princess ship had tested positive for coronavirus. Those who were sick were to remain in Japan to be treated.

Some states call them assisted living facilities; others, residential or personal care homes. These state-licensed facilities promise peace of mind for families whose elders require long-term care. In Vermont and elsewhere, investigations into these homes have revealed lax oversight, injuries and deaths.

Few understand the risks like June Kelly. Her mother, Marilyn Kelly, was energetic and loved to go fishing when she moved into Our House Too, a 13-bed facility that advertised its memory-care expertise. Over the next eight months, almost everything went wrong that could.

Johnpeter Mwolo was 15 when he was diagnosed with Type 1 diabetes.

His body, unable to produce the hormone critical for regulating blood sugar, would now rely on manufactured insulin. He learned to give himself the treatment — four injections a day.

But as he was growing up in Tanzania, insulin was expensive and not always available. Mwolo resorted to rationing his insulin, sharing a vial with his cousin, who also had Type 1 diabetes. "It was one vial to two people," he says. "Many of the necessities that we are supposed to have are not there."

Efforts to stem the tide of teen vaping seem to be a step behind the market. By the time Juul pulled most of its flavored pods from the market in October of 2019, many teens had already moved on to an array of newer, disposable vape products.

As cities across China remain on quarantine lockdown to contain the spread of the new coronavirus, the epidemic is testing the country's ability to get food to its citizens.

Restaurants and cafes have been closed since the end of January, leaving grocery stores as one of the few options for buying food. With families encouraged, or sometimes forced, to stay at home, supplies are often hoarded. Shipments of food from other cities across China take time, as many places have closed off roads.

In love, timing is everything, the saying goes. The same is true for fruit and nut orchards in California's Central Valley, which depend on a synchronized springtime bloom for pollination. But as winters warm with climate change, that seasonal cycle is being thrown off.

Cold is a crucial ingredient for California's walnuts, cherries, peaches, pears and pistachios, which ultimately head to store shelves around the country. The state grows around 99% of the country's walnut and pistachio crop.
