The Democratic Republic of Congo's President Félix Tshisekedi and his Rwandan counterpart Paul Kagame have called for an "immediate ceasefire" in eastern DR Congo, following talks in Qatar. It's the first time the two leaders have met since Rwanda-backed M23 rebels stepped up an offensive in the region, where authorities say seven thousand people have been killed since January. Will the ceasefire be heeded?
Also, there's a rapid increase of weaponised drones across the continent
And why has Sudan suspended all imports from Kenya?

Peter Todd, mistakenly identified as Satoshi in an HBO doc, discusses Bitcoin's technical history, mining economics, block withholding attacks, and controversial ideas like demurrage.
Peter Todd joins us to talk about Bitcoin's technical evolution, discussing terminology like "blockchain" vs "timechain," and revealing flaws in Satoshi's original design. Peter dives deep into mining economics, explaining the risks of block withholding attacks, the problems with activation mechanisms for soft forks, and controversial funding models like demurrage. Despite surviving significant challenges, Bitcoin faces ongoing security concerns as block rewards diminish, requiring creative solutions to ensure mining remains economically viable long-term.
Notes:
- Block withholding attacks remain an unsolved risk
- Mining rewards currently ~0.5% tax on Bitcoin savings
- Bitcoin difficulty algorithm relies on halving events
- Miners have ~24-30% hash power can disrupt network
- Transaction fees alone insufficient for mining economics
- Demurrage could stabilize mining revenue long-term

Colorectal cancer can spread to the liver, and once it does, patients are often at the bottom of the list to receive a liver transplant. But Northwestern Medicine is now offering a new transplant option for select patients that involves splitting a deceased donor liver in two parts.
Reset hears from the first patient to undergo this treatment, Barclay Missen, and one of the surgeons Dr. Zachary Dietch.

A federal judge rules that President Trump's administration likely violated the Constitution when it shut down USAID, but Trump vows to appeal. Hours after Trump and Putin announced a limited ceasefire, Russia and Ukraine launched new attacks, raising doubts about the deal. And Israel breaks the ceasefire with Hamas and resumes airstrikes on Gaza, killing hundreds of Palestinians.
Today's episode of Up First was edited by Jane Greenhalgh, Ryland Barton, Russell Lewis, Alice Woelfle and Mohamad ElBardicy. It was produced by Ziad Buchh, Destinee Adams and Christopher Thomas. We get engineering support from Neisha Heinis, our technical director is Carleigh Strange.
OA1139 and T3BE63 - Lydia's back this week to walk us through Trump's very fashy takeover of The Kennedy Center. She watched it unfold in real-time and while it is obviously disturbing, listening to some leaked audio from the first board meeting provides a lot of laughs. It's somehow real, folks.
And we've got Professor Heather Varanini as always to walk us through the answer to T3BE62, and to set up the question for T3BE63!
If you'd like to play along with T3BE, here's what to do: hop on Bluesky, follow Openargs, find the post that has this episode, and quote it with your answer! Or, go to our Subreddit and look for the appropriate t3BE posting. Or best of all, become a patron at patreon.com/law and play there!

Donald Trump hoped Vladimir Putin would agree to a ceasefire in Ukraine. Instead he made marginal concessions, then launched a missile attack. Our correspondent assesses the implications. Tesla’s falling sales are not just down to Elon Musk’s politics (9:42). And a flowering of literary erotica (15:40).
Yann LeCun is the chief AI scientist at Meta. He joins Big Technology Podcast to discuss the strengths and limitations of current AI models, weighing in on why they've been unable to invent new things despite possessing almost all the world's written knowledge. LeCun digs deep into AI science, explaining why AI systems must build an abstract knowledge of the way the world operates to truly advance. We also cover whether AI research will hit a wall, whether investors in AI will be disappointed, and the value of open source after DeepSeek. Tune in for a fascinating conversation with one of the world's leading AI pioneers.
