Have you ever noticed that in film and on TV, period dramas tend to have almost entirely white casts? It's almost as if, at least in film and TV land, black people do not feature in British history at all. The Guardian's Josh Toussaint-Strauss finds out how accurate costume dramas are in terms of racial diversity, and looks into the reasons why period dramas might get whitewashed
Why are some fully-recovered COVID-19 patients getting the virus again?
FOX News operates the FOX News Channel (FNC), First Lady of New York, Chirlane McCray, says a mental health program to help healthcare workers in New York City will be fully in place in by June, she said, "They are like returning soldiers, and they need the kind of intense support." Aired on 4/29/2020. Not all OPEC nations are rich and can weather a storm like the coronavirus pandemic with oil prices also sliding into negative territory, however briefly.
OPEC cartel leader Saudi Arabia is cutting subsidies and raising taxes but it also has massive foreign currency reserves that can see it through the crisis.
But that is not the case for the likes of Oman and Bahrain, which have slashed budgets, though they could get help from Saudi Arabia and the United Arab Emirates.
Our focus is those resource-rich nations that have had to turn to the International Monetary Fund and those that have not, as oil prices hover just north of $30 a barrel.
Algeria - The North African nation has seen its debt soar to 45 percent of GDP from just 26 percent in 2017. It had based this year's austerity budget on oil prices of $50 a barrel.
Angola - In 2018, Africa's second-biggest oil producer received a $3.7bn loan from the IMF and could be banging on its doors again. It relies on the sale of crude for 65 percent of its tax revenue.
Ecuador - Creditors have given the country a debt payment holiday. But it could still default on its $17bn debt. It also received an IMF loan of more than $600m.

Kola Karim, chief executive of the Shoreline Group, which has holdings in a number of Nigerian oil ventures, shares his thoughts with Al Jazeera.
Lithium vs Oil
This is the stuff of science fiction.
Wuhan University has developed a plasma thruster, a type of propulsion engine, that could potentially power the planes of tomorrow, and bring emissions-free flying a step closer.
The pandemic has reduced global consumption of oil by about a third - with grounded jet airlines guzzling at least 5 million barrels of oil daily.
The coronavirus may just be the push green energy needs. It should come as no surprise that decline in fossil fuel usage has led to a fall of 8 percent in global carbon dioxide emissions, according to the International Energy Agency.
Andy Leyland, head of strategic advisory at Benchmark Minerals, discusses whether lithium, the stuff that powers much of our electric cars, can emerge as a winner from this crisis.
Saudi Arabia's 'sports washing'
Newcastle United could be in the hands of new owners very soon.
But the buyer comes with a lot of baggage. Saudi Arabia's Public Investment Fund will own 80 percent of the English Premier League club.
Saudi Arabia's human rights record, the killing of journalist Jamal Khassoggi and the country's alleged theft of Middle Eastern Premier League rights could derail the $375m deal.
Amnesty has accused Crown Prince Mohammed Bin Salman of using the glamour and prestige of the Premier League to cover up actions that are deeply immoral.
Simon Chadwick, director at the Centre for the Eurasian Sport Industry, comments on Saudi Arabia's "sports washing". Moscow says its levels of tesing are the reason it has just a few hundred COVID-19 cases.
