In 2018, the electric car maker, Tesla, was struggling to get the Model 3 electric vehicle off the production line. Its CEO, tech entrepreneur Elon Musk, was working up to 22 hours a day on the factory floor, trying to solve a host of problems on the car he’d bet the company on. It was close to running out of money. Two years later, the company’s doing better. It says it will grow 30-40% this year.No surprise then that Tesla’s share price has gone up. But the amount may surprise you – up eight fold in the last year, to $400 a share.

In July, billionaire musician Kanye West announces on Twitter that he’s standing as a candidate in November’s US presidential election. After a scramble to meet the registration deadlines, his name is on the ballot in fewer than 20 states. His manifesto is confusing, his motive unclear.In the past, Kanye West has been a vocal supporter of president Donald Trump. And it seems his campaign is being run largely by those with close ties to the Republican party. The Democrats say his entry in the race as an independent third party candidate is a dirty trick by Republicans. Others claim it’s simply a publicity stunt to promote his new album. But, in battleground states, where every vote counts, could his celebrity status have a significant impact on the election result? How seriously should we take Kanye West’s run for president?

The massive explosion that tore through Beirut on August 4th left more than 200 people dead, 6,000 injured, and as many as 300,000 homeless. The explosion was caused by a fire that ignited 2,750 tons of ammonium nitrate stored at the port. When the blast hit, Lebanon was already in the middle of an unprecedented economic and political crisis that has triggered hyperinflation, poverty, and hunger. Many Lebanese feel that the blast was not the cause of catastrophe in Lebanon, but the result of it.

Researchers around the world are racing to develop a vaccine against Covid-19, with more than 170 candidate vaccines now in development. Most vaccines take years of testing and additional time to produce at scale, but scientists are hoping to develop a coronavirus vaccine at record speed. Several potential vaccines are now in the final phase of testing but it could still be months before we discover if they are safe and can effectively prevent people from being infected. If a vaccine can be found, there are concerns about how the world will manufacture enough. There may be challenges in storing it at the right temperature and transporting it safely around the world. Plus, rich countries might hoard supplies. Although hopes are high it is entirely possible that a safe and effective vaccine is a long way off, or never discovered. Experts warn that ‘waiting for a vaccine syndrome’ could be distracting us from finding other solutions for controlling the spread of Covid-19.Presenter: Tanya Beckett(A scientist works on an experimental coronavirus vaccine at a laboratory in Buenos Aires, Argentina.
