The Download: longevity for the uber-rich, and wrongful prosecutions of Chinese scientists

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

Inside the billion-dollar meeting for the mega-rich who want to live forever

Back in September, Jessica Hamzelou, our senior biotech reporter, traveled to Gstaad, a swanky ski-resort town in the Swiss Alps, to attend the first in-person Longevity Investors Conference.

Over the two-day event, scientists and biotech founders made the case for various approaches to prolonging the number of years we might spend in good health. The majority of them were trying to win over deep-pocketed investors.

As the field of longevity attempts to define itself as scientifically sound, plenty of anti-aging treatments" based on little-to-no human evidence continue to enter the market. But can billions of investor money-some of it from ethically dubious sources-ever offer a concrete path to evidence-based life extension? Read the full story.

Read more about the quest to extend our healthy years:

+ How scientists want to make you young again. Research labs are pursuing technology to reprogram" aging bodies back to youth. Read the full story.

+ Aging clocks aim to predict how long you'll live. These clocks promise to measure biological age and help identify anti-aging drugs, but there are lingering questions over their accuracy. Read the full story.

A big settlement for one Chinese-American scientist won't end wrongful prosecutions

Last week, our senior investigative reporter Eileen Guo wrote about a historic settlement won by Chinese-American scientist Sherry Chen, who was wrongly accused of being a Chinese spy.

Her case illustrates just how hard it is to go up against a powerful federal agency and hold it accountable. It's also an anomaly-it's usually incredibly difficult to prove racial bias in court, but a broad pattern of misconduct by her accusers was proven definitively.

However, Chen's win doesn't necessarily mean others in her situation will have an easier time getting justice. Read the full story.

The big story

The delivery apps reshaping life in India's megacities

From 7am until well past dusk, seven days a week, N. Sudhakar sits behind the counter of his hole-in-the wall grocery store in the south Indian city of Bangalore. Packed floor to ceiling with everything from 20-kilogram sacks of rice to one-rupee ($.01) shampoo sachets, this one-stop shop supplies most of the daily needs for many in the neighborhood. It's a carbon copy of the roughly 12 million family-run kiranas" found on almost every street corner in India.

Increasingly, the technology industry is presenting stores like his with a new challenge. Across the road, a steady stream of delivery drivers line up to grab groceries from a dark store"-a mini-warehouse built to enable ultra-fast deliveries run by Dunzo, a Bangalore-based startup.

In India's megacities, the urban middle class is gradually getting hooked on online shopping. These shoppers make up a fraction of the population, but their spending power is considerable, and in more affluent pockets of big cities, the battle for India's street corner is well underway.
