Updates in recent Node Modules Inspector: - Better module type detection (now it recognizes binary packages) - Colorizing the charts by module type, published age, or duplicated versions to find them easily

Robots that act like slime! 🫟 Cornell University engineers developed a robotic collective that behaves less like a machine and more like a material that flows, reshapes, and adapts without centralized control. It consists of dozens of small robots with limited individual mobility that exhibit coordinated motion when entangled. The system resembles soft matter, continuously deforming and reorganizing as it moves, driven by mechanical intelligence. Each robotic module measures 200mm long and 20mm wide, containing a small motor that oscillates between "I" and "U" shapes. These oscillations generate forces against the ground, allowing modules to inch forward and jostle together. On their own, modules move slowly and inefficiently. When they entangle into chains, they self-organize into shifting configurations that prove resilient in challenging environments. On incline surfaces, chains moved more reliably than individuals. In obstacle fields, the collective behaved like a flowing material, connections formed to maintain cohesion, then broke apart to prevent jamming. The system stays functional even when modules fail. Isolated modules emit an audible distress signal, prompting nearby modules to slow down so the straggler can reconnect. No centralized sensing or control, each module infers when it has lost contact by how much it's being jostled. Read more here: ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

Stateless History Node is almost like a regular Ethereum node, but it doesn't store state and it doesn't have EVM execution. It's used only for syncing events and thus - is faster and gives you FREE INDEXING. You don't have to pay 6 figures for RPC anymore! Just spin up a Stateless History Node, plug rindexer or Ponder there, and enjoy free (AND FAST!!) indexing! This node is syncing >1000 blocks per second at my local pc (less than 6hrs for the whole Ethereum), and it should use less than 200GB - which means you can host it on a MacMini, Hetzner or whatever. You can futhermore filter that by using block ranges or bloom filters, etc - I haven't developed this yet. What you see is a proof of concept. It works via native devp2p 'eth' protocol, but with EIP4444 and The Prune we would have to also support era1 archives and Portal Network. But so far it works - there are plenty of peers serving historical receipts, and they serve them FAST! If you run Stateless History Node you can also serve the blocks and receipts - so that could help to preserve archival data too. For now there is no data validation yet (and even no data storage - that's a very early PoC), but we can verify validity of chain by simultaneously running a lightweight CL node (or not lightweight if you're extremely paranoid). And then support verifying the hashes of receipts and blocks with their parents, maintaining full integrity and zero trust. It's also written in rust, btw. So, I guess, at least for Ethereum Mainnet the era of RPC's pumping moneybags is over - there's finally a local, trustless and free indexing alternative available. Too sad this won't work for Optimism / Base , cause despite introducing P2P after Bedrock - they haven't enabled receipts transfer in the protocol (or at least I couldn't find one). Arbitrum is even sadder - I don't believe there is a P2P layer at all - you just have to run your own node, hold state and execute blocks to get events. There is hope - Paradigm recently released Ress - stateless execution, but it requires nodes to support Witness preparation & exchange - but this could work for L2s - cause the main blocker for local RPCs rn is huge state (VPS with TB storage cost a lot), and the second blocker is EVM forks makes it hard to hold a node - it needs to be maintained, upgraded, etc. Ress at least solves the state part. But anyways, I will try to continue working on this and release some MVP version with RPC endpoint and data storage soon - follow the updates!

Facial reconstruction of a 3,800-year-old man from Sapalli Tepe, Uzbekistan The Bronze Age settlement of Sapalli Tepe was located near mountain streams flowing from the Kugitangtau range in southern Uzbekistan. It was discovered in 1958 by D. I. Albaum and fully excavated between 1969-1974 by A. Askarov. Finds from Southern Uzbekistan showed the region was one of the centers of ancient agricultural civilization in the East. Sapallitepa became one of the earliest known sedentary farming sites of Northern Bactria from the Mature Bronze Age. The site consisted of a fortress and surrounding settlement. The fortress, about 1 hectare in size, had triple defensive walls and over 150 rooms arranged into quarters separated by narrow streets. A. Askarov considered it an independent archaeological culture linked with sites in Northern Afghanistan and other parts of Surkhandarya, including Djarkutan. The population formed part of a broader ethnocultural network of related sedentary farming tribes across the region. The skulls from Sapallitepa belong to a single morphological type in both males and females. Most are long-headed with ellipsoid or ovoid shapes; a few broader skulls are considered normal variation rather than evidence of brachycephalic admixture. The series is characterized by narrow, well-profiled faces, medium-high orbits, and projecting noses. Overall, the population shows strongly Europoid features and is closest to Bronze Age eastern Mediterranean-type groups from northeastern Iran, Tajikistan, and Uzbekistan, including Djarkutan.
