The Download: inside the US defense tech aid package, and how AI is improving vegan cheese
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.
Here's the defense tech at the center of US aid to Israel, Ukraine, and Taiwan
After weeks of drawn-out congressional debate over how much the United States should spend on conflicts abroad, President Joe Biden signed a $95 billion aid package into law last week.
The bill will send a significant quantity of supplies to Ukraine and Israel, while also supporting Taiwan with submarine technology to aid its defenses against China. It's also sparked renewed calls for stronger crackdowns on Iranian-produced drones.
James O'Donnell, our AI reporter, spoke to Andrew Metrick, a fellow with the defense program at the Center for a New American Security, a think tank, to discuss how the spending bill provides a window into US strategies around four key defense technologies with the power to reshape how today's major conflicts are being fought.

This creamy vegan cheese was made with AI
Most vegan cheese falls into an edible uncanny valley full of discomforting not-quite-right versions of the real thing. But machine learning is ushering in a new age of completely vegan cheese that's much closer in taste and texture to traditional fromage.
Several startups are using AI to design plant-based foods including cheese, training algorithms on datasets of ingredients with desirable traits like flavor, scent, or stretchability. Then they use AI to comb troves of data to develop new combinations of those ingredients that perform similarly. But not everyone in the industry is bullish about AI-assisted ingredient discovery.

The big story
How big science failed to unlock the mysteries of the human brain
In September 2011, Columbia University neurobiologist Rafael Yuste and Harvard geneticist George Church made a not-so-modest proposal: to map the activity of the entire human brain.
That knowledge could be harnessed to treat brain disorders like Alzheimer's, autism, schizophrenia, depression, and traumatic brain injury, and help answer one of the great questions of science: How does the brain bring about consciousness?
A decade on, the US project has wound down, and the EU project faces its deadline to build a digital brain. So have we begun to unwrap the secrets of the human brain? Or have we spent a decade and billions of dollars chasing a vision that remains as elusive as ever? Read the full story.
