The Download: a hepatitis mystery, and chasing crypto
The news: Hundreds of young children around the world have developed severe cases of hepatitis with no obvious cause, leaving doctors baffled. But two new studies reveal the potential culprits: a combination of genetic factors, lockdowns, and at least two viruses.
Researchers believe the common adenovirus and another adeno-associated virus may be triggering the unexplained hepatitis in children with a gene that affects the way the immune system works. Lockdowns inadvertently seem to have played a part as adenoviruses surged as people began to mingle more after they were lifted.
Why it matters: Although the World Health Organization reported 1,010 probable cases of the liver condition in 35 countries as of July 8, the true number of cases is likely to be higher. The situation is serious—around 5% of the children infected worldwide have needed liver transplants, and 22 have died.
What’s next?: Although researchers are still not confident which of the viruses is causing the condition, or which first infected a child, the small studies offer some much-needed insight into why the mysterious condition appears to be so widespread. They could also help to shed light on previous, similar cases that could have been trickling along for years. Read the full story.
How governments seize millions in cryptocurrency
There have been so many recent multimillion-dollar cryptocurrency thefts that it’s easy to lose track. Organized crime, bad cybersecurity, financially motivated spies, and colorful criminals of all kinds have made so many headlines that even huge heists can go mostly unnoticed by the public.
But sometimes the government is able to get it back. Last week, the United States seized $500,000 in cryptocurrency from alleged North Korean hackers who got that money by extorting American medical organizations. That’s just a drop in the bucket considering the grand total: the IRS alone seized $3.5 billion in cryptocurrency in 2021.
Read our explanation on how the government tries to track, freeze, and seize stolen cryptocurrency—and what comes next.

The big story
Inside the machine that saved Moore’s Law
In Wilton, Connecticut, Dutch company ASML is making the world’s most sophisticated machine for lithography—a crucial process used to create the transistors, wires, and other essential components of microchips. The team’s speed and accuracy is key to keeping up with Moore’s Law—the observation that the number of transistors crammed into a microchip doubles roughly every two years as components become ever smaller, making the chips cheaper and more powerful.
It took ASML $9 billion of R&D and 17 years of research to refine its industry-leading extreme ultraviolet (EUV) microchip machine. But the effort and time it took to make it happen raises some inevitable questions. How long will EUV be able to keep Moore’s Law going? And what will happen next? Read the full story.
