Each weaver ant can pull on a leaf much harder when in a group than when it works alone. The ants’ sticky feet and coordinated legwork, researchers believe, improve the ants’ collective efficiency—a finding that may provide insights into how to build and coordinate swarms of robots that work... show more

Cornell engineers have developed a robotic collective that behaves less like a machine and more like a material that flows, reshapes, and adapts to its environment without centralized control. The system, called the Cross-Link Collective, consists of dozens of small robots that have limited mobility individually, but together exhibit coordinated and sustained motion. The research, published May 20 in Science Robotics, demonstrates a robotic system that resembles soft matter, continuously deforming and reorganizing as it moves, driven by what researchers call mechanical intelligence.

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 →

An ant mill is a phenomenon in which a group of ants, separated from the main party, lose the pheromone track and begin to follow one another. This is commonly known as a "death spiral" because the ants might eventually die of exhaustion. 🔄 🐜😲

Before telling you about butterflies generally, let me tell you something spectacular about THIS butterfly. Its name is Alcon blue butterfly. It is one of the most famous examples of an extreme social parasite in the butterfly world. How the deception works: After the female Alcon Blue lays her eggs and they hatch, feeds on the plant for about 2–3 weeks, going through its first three instars (growth stages). When it reaches the fourth instar, the caterpillar drops to the ground and waits. It secretes chemicals (allomones) from a special gland that mimic the exact scent profile of the brood (larvae/pupae) of a myrmica ants. When the worker ants encounter the caterpillar, they'll mistake it for one of their own lost larvae, and carry it back into their underground nest. In some populations, the caterpillar even makes tiny sounds that imitate the “queen ant” calls, which elevates its status inside the colony. Ants will actually prefer feeding the caterpillar over their own larvae! The caterpillar then becomes a ruthless predator and eats hundreds of ant grubs over the next 10–22 months. After almost a year (or even two in some cases), the caterpillar pupates inside the ant nest. The adult butterfly emerges, inflates its wings, and crawls out of the nest (often at dawn when ants are less active). The ants don’t attack it because its scales reduce friction and it may release calming chemicals.

Leaf-cutter ants are one of the few species that practice a form of agriculture. These ants cut pieces from leaves, bring them back to their colony, and use them as a substrate to grow a specific type of fungus. This fungus serves as the colony's primary food source.⬇️1/2

In the legends of the Hopi, there are stories about beings called the Ant People. These beings are said to have lived underground and helped the Hopi during times of great danger. One of the main stories says that during earlier worlds, when disasters like fire or ice came, the Ant People guided some of the Hopi into tunnels beneath the earth to keep them safe. Down there, they were given food and taught how to survive until it was safe to return to the surface. The Ant People are described as hardworking and cooperative, much like ants themselves, and they are remembered as helpers rather than rulers. The stories also say the Ant People shared knowledge with the Hopi. This included how to store food, live simply, and work together as a group. In some versions, they helped guide people between different “worlds,” which are seen as cycles of time where each world ends and another begins. These teachings are still reflected in Hopi values today, especially the idea of living in balance and preparing for hard times. The underground setting is an important part of the story, and many see it as both a real place and a symbol of protection and survival during periods when the surface world becomes unstable.

Some birds engage in one of nature’s strangest rituals — anting, the act of picking up live ants and rubbing them all over their feathers. It might look bizarre, but it’s a brilliant survival strategy ⚡️😲 When ants are disturbed, they release formic acid, a natural chemical that helps kill parasites, bacteria, and mites hiding in the bird’s plumage

The last weekend gave me much motivation from the new generation. They have a sense of feeling and way of thinking that I don't have, and I feel that I have a lot to learn and need to work even harder.

I don't think there's a single terminal ux that handles agent swarms well With slate, you can literally use Opus 4.6 and GPT 5.4 at the exact same time But making it intuitive took a ton of work So heres a thread on how it works and how to actually use it 🧵

Well, a humanoid robot can move on two legs or wheels, depending on the environment it faces. AGIBOT (Zhiyuan) from Shanghai revealed that their new generation of humanoid robot "Nezha" can autonomously switch to two wheels for fast movement when walking on two legs. Imagine that in the airport hall, when he walks down the stairs and sees a fallen object not far away, it can transform into a wheeled robot and move quickly to pick it up. Or in elderly care, when it see an elderly person fall, it can quickly move and help the elderly person up, and quickly provide medical supplies to the caregiver.
