How lasers could help provide fuel for nuclear reactors 

Nuclear power provides about 9% of global electricity today, and that fraction could tick up as countries look to build new reactors. New, cheaper methods to obtain fuel could help ensure that those nuclear projects stay on track.

One of those methods is called laser enrichment. It allows you to separate out the material you want (in this case, uranium) from others in a mixture of old waste.

A company called Global Laser Enrichment (GLE) is about to start testing whether the technology works at commercial scale. Read our story about their efforts.

The quest to keep organs alive outside the body

It’s super difficult to freeze organs. Once ice forms in them, they’re done. The ice crystals create all kinds of damage and render the organs unusable. That hasn’t stopped many researchers from trying.

In new research, one team has been able to supercool the kidneys of pigs and preserve them for days. The kidneys survived being stored at −4 °C (25 °F) and eventually reimplanted back into pigs. And that’s just the latest development in a field that is positively buzzing.

Read about why it’s such an exciting time for organ preservation—and what could be coming next.

Inside a romance scam compound—and how people get tricked into being there  

Gavesh’s journey started, seemingly innocently, with a job ad on Facebook promising work he desperately needed. 

Instead, he found himself trafficked into a business commonly known as “pig butchering”—a form of fraud in which scammers form close relationships with targets online and extract money from them. 

The Chinese crime syndicates behind the scams have netted billions of dollars, and they have used violence and coercion to force their workers to carry out the frauds from large compounds, several of which operate openly in the quasi-lawless borderlands of Myanmar. 

Read our story about these scam syndicates and how they could be broken up.

Supercooled kidneys have been transplanted into pigs in a “landmark achievement” 

When it comes to organ donation, time is everything. As soon as an organ has been removed from a donor’s body, it starts to deteriorate. Surgeons have only a matter of hours to get it into a recipient.

In most cases, organs will be kept on ice during that time, at around 4 °C (39 °F). They cannot be frozen—in previous attempts, ice has formed, causing all kinds of damage.

But now, scientists have come up with a device that allows organs to be cooled to -4 °C (25 °F) without forming any ice. They’ve tested it with pig organs and shown that kidneys, at least, can be preserved in the device for days then successfully transplanted. 

Read our story about their breakthrough, and why it raises hopes for longer-term storage of donated human organs.

AI is changing how we study bird migration

In a warming world increasingly full of human infrastructure that can be deadly to them, like glass skyscrapers and power lines, migratory birds are facing many existential threats. 

Scientists rely on a combination of methods to track the timing and location of their migrations, though each has shortcomings. But now, machine-learning tools are unlocking a treasure trove of acoustic data for ecologists. 

Read our story about the technology that’s making it easier to detect and identify birds and their movements.

The power line that could reshape New York’s grid is hitting snags 

During a heat wave on July 3, New York State’s grid imported enough electricity from Canada to meet about 9% of its total demand that day.

Some of that power shuttled in on a 339-mile power line stretching from Quebec to Queens. It opened in May and is officially the longest underground transmission line in North America. It could provide up to 20% of New York City’s electricity demand, largely with abundant hydropower from Quebec.

One wrinkle: The line has been down for most of this month, and some experts are concerned about how drought will affect the power supply feeding it. 

Still, the line could help shape the future of our grid, if it can overcome these sorts of snags. Read our story to understand how.

Welcome to the dark side of crypto’s permissionless dream 

Jean-Paul Thorbjornsen is a founder of THORChain, a blockchain through which users can swap one cryptocurrency for another and earn fees from making those swaps.  

But is he responsible for what it’s used for? It’s a question that matters because in January last year, its users lost more than $200 million in cryptocurrency after THORChain transactions and accounts were frozen by an admin override, which users believed was not supposed to be possible given the decentralized structure. It’s also been used by North Korean hackers to move $1.2 billion of stolen ethereum. 

Thorbjornsen explains this all away as a function of THORChain’s decentralized and permissionless nature. Read our story exploring whether we should believe him or not.
