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 →

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.

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.

Danielle Smith gets booed at the UCP AGM. Does Canada work? "I hope people, today, feel a lot more confident that Canada works than they did a couple of days ago." A Canada that works doesn't need Alberta to submit to UN/WEF climate agendas in order to have an economy. A Canada that works doesn't try to replace its citizens with foreigners. A Canada that works doesn't take billions of dollars more from Alberta than we get back. No, Canada and its record debt on top of it, doesn't work.

Like a stadium full of sports fans doing the wave, neurons coordinate their electrical signals in rhythmic patterns that sweep across the cortex, the brain’s outermost layer. Recent studies in humans and animals have shown these patterns, called traveling waves, can take on complex shapes, among them a rotating spiral that has been observed during deep sleep, memory retrieval, and other brain processes. A new study has now captured the fast-spinning waves spanning whole brains, offering clues to how they’re organized and what they might do. Learn more: News from Science

Faith in humanity is the conviction that, given sufficient will, the collective mind is capable of shaping a civilization in which dignity, freedom, and mutual care become a stable norm of social existence. : The author defines faith in humanity as the deep conviction that, with sufficient collective will, the shared human mind can build a civilization where dignity, freedom, and mutual care form the stable norm of social life. This faith is not blind optimism. It is a deliberate trust in our capacity to choose better. It recognizes the raw material: minds capable of empathy, foresight, and cooperation. The challenge is to direct that capacity toward lasting structures that protect every person’s worth, liberty, and security. When dignity is no longer a privilege but the default, when freedom is paired with responsibility, when care for others is woven into the fabric of society, then humanity proves its own faith justified. The alternative is resignation: accepting division, exploitation, and indifference as inevitable. Faith in humanity rejects that surrender. It insists that we are not condemned to repeat the past. We can decide, together, to make mutual care the rule rather than the exception. That decision is the quiet revolution faith demands. It begins with the belief that we are capable of it. And it ends with a world that finally matches the best of what we are.

QUOTE 1 - Love for life and rationality are essential for life to become a source of joy and flourishing. : Love for life and rationality are not optional extras. They are the essential foundation that turns mere existence into a source of genuine joy and flourishing. Love for life brings warmth, gratitude, and a deep appreciation for the gift of being alive. It fuels curiosity, resilience, and the desire to protect and nurture what is beautiful. Rationality, in turn, provides clarity, honesty, and the ability to navigate reality without illusion. Together, they create a powerful synergy: a heart that cherishes life guided by a mind that understands it. Without love for life, rationality can become cold and empty. Without rationality, love for life can become blind or fragile. When both are present and balanced, life stops being a struggle to endure and becomes something worth celebrating every day. This combination allows us to face difficulties with courage, find meaning in ordinary moments, and build a future worth living in. It is the quiet secret to a flourishing existence. QUOTE 2 - Love is the only force that turns millions of individuals into a nation, and nations into humanity. : Love is the only force powerful enough to turn millions of separate individuals into a genuine nation, and nations into a united humanity. Laws can regulate behavior, shared interests can create alliances, and culture can foster identity, but only love creates the deep emotional bond of belonging and mutual care. It transforms “them” into “us.” It makes people willing to sacrifice, to protect, to build together rather than merely coexist. On a larger scale, the same principle applies. When love extends beyond national borders, it turns competing states into parts of a single human family. Without this connecting force, unity remains fragile, easily broken by fear or self-interest. With it, differences become complementary rather than divisive. Love is the invisible thread that holds humanity together. It is what makes a nation more than a territory, and humanity more than a collection of nations. In the end, the strength and future of both depend not on power or wealth, but on our capacity to love one another.
