How China is fighting back in the semiconductor exports war
China has been on the receiving end of semiconductor export restrictions for years. Now, it’s striking back with the same tactic.
On July 3, the Chinese Ministry of Commerce announced that the export of gallium and germanium, two elements used in producing chips, solar panels, and fiber optics, will soon be heavily restricted. Exports of the materials will need to be approved by the government, and Western companies that rely on them could have a hard time securing a supply.
Even though the news immediately sent the price of gallium and germanium up, the curbs are not likely to hit the US as hard as American export restrictions have hit China. Zeyi Yang, our China reporter, explains why. Read the full story.

Why everyone is mad about New York’s AI hiring law
Last week, a law about AI and hiring went into effect in New York City, and everyone is up in arms about it. It’s one of the first AI laws in the country, and so the way it plays out will offer clues about how AI policy and debate might take shape in other cities.
AI hiring regulation is part of the AI Act in Europe, and other states in the US are considering similar bills to New York’s. But the law has been met with significant controversy—with public interest groups and civil rights advocates saying it isn’t enforceable and extensive enough. Read the full story.

The big story
How big science failed to unlock the mysteries of the human brain
August 2021
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 at the level of individual neurons and detail how those cells form circuits.
That knowledge could be harnessed to treat brain disorders like Alzheimer’s, autism, schizophrenia, depression, and traumatic brain injury, and would 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. Did it achieve anything? Or have we spent a decade and billions of dollars chasing a vision that remains as elusive as ever? Read the full story.
