Scientists have discovered a massive, intact 34-million-year-old landscape preserved beneath the East Antarctic Ice Sheet. Deep beneath the East Antarctic Ice Sheet lies a vast, ancient world frozen in time. Researchers utilizing satellite data and advanced radio-echo sounding have mapped a 12,000-square-mile territory beneath Wilkes Land, revealing an intact landscape of deep river valleys, steep ridges, and high plateaus. Unlike most areas where moving glaciers violently grind down the bedrock, this prehistoric terrain has been miraculously protected and sealed away by cold, slow-moving ice for up to 34 million years. This incredible find offers a pristine window into a time when Antarctica was warm, vegetated, and potentially covered in lush forests. Beyond its historical allure, mapping this subglacial topography is vital for predicting our planetary future. The shape of the bedrock governs how ice sheets move: deep valleys can rapidly channel melting ice into the ocean, while elevated plateaus act as natural speed bumps that help stabilize the ice. By understanding this hidden geography, climate scientists can significantly improve their projections of how East Antarctica will respond to a warming globe. As global temperatures rise, this ancient time capsule is proving to be a critical guide for what lies ahead. source: Jamieson, S. S. R., Ross, N., Paxman, G. J. G., Clubb, F. J., Young, D.

It is finally here: our last blog of the decentralization series. Now it is time to dig into what interests us the most: blockchains and decentralization. In part 3, the research team tackles decentralization measurement, how security goes beyond it, and shows what Polkadot has done since day one to strengthen it. The major takeaway from our series is simple: even though decentralization is difficult to achieve, the advantages of decentralized applications over centralized ones should make us strive for it. parity.io/blog/a-technic…

Introducing the folding balcony. It's a genius idea, but requires nerves of steel if you're on the 50th floor.

This is huge. For decades, computing advanced by cramming in more transistors. This research points to a different future. Researchers just demonstrated a ZnO-Te semiconductor device that could help redefine how future chips are built. "For a frequency quadrupler, the team achieved the same function using one device instead of four transistors, cutting component count by 75%." "The device exhibits Double Negative Differential Transconductance (D-NDT), allowing a single component to perform functions that normally require multiple devices." "Researchers also demonstrated approximately 4× faster signal processing compared to conventional approaches." Acceleration is everywhere!

Full nodes verify every state transition and store the entire chain history. That's significant overhead for most applications. Polkadot's light clients verify state using only cryptographic proofs and block headers. A mobile wallet built with PAPI and smoldot verifies account state through Merkle proofs against block headers. Verification happens inside the app itself. No third-party node. No infrastructure to run or trust. • Works across multiple chains simultaneously. • Runs inside the application itself. • Minimizes trust by default. Secure blockchain access without the overhead.

Most blockchains ask validators to see everything. ELVES changes that. The research team at @Web3foundation built ELVES so that a random subset of validators can verify each block, rather than the full set, unless needed. Each validator does less work, but the network as a whole does more. Smaller validation surface. More throughput per set. Same security. Higher throughput. The result is a system that scales without asking every validator to carry the full load.
