The Download: cancelling out noises, and tastes like (lab-grown) chicken

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.

Noise-canceling headphones could let you pick and choose the sounds you want to hear

The news: A new system for noise-canceling headphones lets users opt back in to certain sounds they’d like to hear, such as babies crying, birds tweeting, or alarms ringing. 

How it works: The system, which is still in prototype, connects off-the-shelf headphones to a smartphone app. The microphones embedded in these headphones, which are used to cancel out noise, also detect the sounds in the world around the wearer. These sounds are then played back to a neural network, which has been trained to recognize 20 everyday noises; then certain sounds are boosted or suppressed in real time, depending on the user’s preferences. 

Why it matters: Researchers have long tried to solve the “cocktail party problem”—that is, to get a computer to focus on a single voice in a crowded room, as humans are able to do. Experts say this new method is a significant step forward, and could pave the way for smarter hearing aids and earphones. Read the full story.

I tried lab-grown chicken at a Michelin-starred restaurant

Last week, our climate reporter Casey Crownhart paid a visit to Bar Crenn, a Michelin-starred spot and one of two restaurants in the US currently serving up lab-grown meat. She was served a one-ounce sampling of cultivated chicken, made in the lab by startup Upside Foods, coated with a recado negro tempura crust, and topped with edible flowers and leaves. 

Cultivated meat, also called cultured or lab-grown meat, is meat made using animal cells—but not animals themselves. It’s a growing business. But does it really taste like chicken? Read Casey’s full review.

Why battery recycling is so important

Until the day comes when we can recharge batteries in perpetuity, we’ll need to solve the problem of a rapidly growing pile of discarded batteries. This is just one of the fascinating topics we’ll be exploring at EmTech MIT 2023, our flagship technology event kicking off 14 November.

The big story

I took an international trip with my frozen eggs to learn about the fertility industry

September 2022

—Anna Louie Sussman

Like me, my eggs were flying economy class. They were ensconced in a cryogenic storage flask packed into a metal suitcase next to Paolo, the courier overseeing their passage from a fertility clinic in Bologna, Italy, to the clinic in Madrid, Spain, where I would be undergoing in vitro fertilization.

The shipping of gametes and embryos around the world is a growing part of a booming global fertility sector. As people have children later in life, the need for fertility treatment increases each year.

After paying for storage costs for six and four years, respectively, at 40 I was ready to try to get pregnant. Transporting the Bolognese batch served to literally put all my eggs in one basket. Read the full story.
