The Download: growing Africa’s food, and deleting your 23andMe data

This is today's edition ofThe Download,our weekday newsletter that provides a daily dose of what's going on in the world of technology.

Africa fights rising hunger by looking to foods of the past

After falling steadily for decades, the prevalence of global hunger is now on the rise-nowhere more so than in sub-Saharan Africa.

Conflicts, economic fallout from the covid-19 pandemic, and extreme weather events linked to climate change have pushed the share of the population considered undernourished from 18% in 2015 to 23% in 2023.

Africa's indigenous crops are often more nutritious and better suited to the hot and dry conditions that are becoming more prevalent, yet many have been neglected by science, which means they tend to be more vulnerable to diseases and pests and yield well below their theoretical potential.

Now the question is whether researchers, governments, and farmers can work together in a way that gets these crops onto plates and provides Africans from all walks of life with the energy and nutrition that they need to thrive, whatever climate change throws their way. Read the full story.

How to... delete your 23andMe data

Things aren't looking good for 23andMe. The consumer DNA testing company recently parted ways with all its board members but CEO Anne Wojcicki over her plans to take the company private. It's also still dealing with the fallout of a major security breach last October, which saw hackers access the personal data of around 5.5 million customers.

23andMe's business is built on taking DNA samples from its customers to produce personalized genetic reports detailing a user's unique health and ancestry. The uncertainty swirling around the company's future and potential new ownership has prompted privacy campaigners to urge users to delete their data. Caveats apply... but here's how you can do it.

The big story

Minneapolis police used fake social media profiles to surveil Black people

April 2022

The Minneapolis Police Department violated civil rights law through a pattern of racist policing practices, according to a damning report by the Minnesota Department of Human Rights.

The report found that officers stop, search, arrest, and use force against people of color at a much higher rate than white people, and covertly surveilled Black people not suspected of any crimes via social media.

The findings are consistent with MIT Technology Review's investigation of Minnesota law enforcement agencies, which has revealed an extensive surveillance network that targeted activists in the aftermath of the murder of George Floyd. Read the full story.
