Why should an organism, like the green crab spider (Diaea dorsata), have two eyes? In nature, eye number often evolves based on specific environmental and survival needs. Many spiders, for example, have multiple eyes (usually eight), allowing them to detect movement and focus on prey from various angles, even in low light.

In the case of this spider, its visual system with multiple eyes maximizes its ability to detect predators and prey across its environment, providing a critical survival advantage. So, while many creatures, including humans, have two eyes for a stereoscopic vision that enhances depth perception, spiders need a broader field of vision due to their predatory and defensive strategies.

In an image captured at 20x magnification by Pavel Blachowicz, this green crab spider, adorned with eyes, shows how evolution has tailored its visual apparatus for survival in its habitat.

If you’re wondering, no, this isn’t a scene from the latest Alien movie.

What the fisherman is holding is a wolf eel, a fascinating creature found in the northern Pacific Ocean. It can grow up to 2.5 meters long!

Despite its fearsome appearance, the wolf eel mainly feeds on crustaceans and mollusks and rarely hunts fish.

Why Men and Women Experience Pain Differently

It is well-known that men and women perceive pain and respond to analgesics in distinct ways.

A recent study involved 98 participants, both healthy individuals and those suffering from chronic lower back pain. They were trained in pain-relieving meditation techniques. Some participants received a high dose of naloxone—a drug that blocks opioid receptors—before meditating to improve their well-being.

In men, naloxone completely neutralized the pain-relieving effects of meditation. In contrast, for women, it even slightly enhanced the relief. Meditation showed significant benefits for participants with back pain who did not receive naloxone.

The study concludes that men rely on opioid receptors for pain relief, while women engage other biological mechanisms to manage pain.

🚀 The Largest Prime Number Ever Discovered!

The GIMPS project has identified the 52nd Mersenne prime, which is now the largest known prime number. This mathematical giant has the form and spans more than 40 million digits! The discovery was made possible through distributed computing, with thousands of volunteers worldwide contributing their computing power.

Tyrannosaurus Rex vs. Emu Foot: Spot the Difference

In 2008, American scientists studied the fossilized remains of a Tyrannosaurus Rex and concluded that the closest living relatives of the mighty T-Rex are none other than ostriches and chickens. Evolution certainly knows how to surprise!

Hydra Under the Microscope

The hydra preys on invertebrates, most often small crustaceans. It extends its tentacles, waiting patiently for its target. When the prey touches the tentacles, it is struck by the hydra’s stinging cells.

EngineAI Unveils SE01 Humanoid Robot with Natural Gait

The young Shenzhen-based startup EngineAI has announced a full-sized humanoid robot, SE01.

What sets SE01 apart is its unique biomechanics, offering smooth, natural movements with 12 degrees of freedom.

The development team consists of experts from UC Berkeley, Tsinghua University, and the Beijing Institute of Technology.

A friendly shoutout to everyone who used to laugh at awkwardly moving robots — the engineers in China have made their point loud and clear! 🤖

The real fear begins when these machines become indistinguishable from humans. Now imagine if it had the cognitive capabilities of Anthropic’s AI or a 1TB model within the next decade.
There might be no place left for humans — not in manufacturing, services, or even daily life.

A Strange Spider Within a Spider: Cyclosa’s Astonishing Decoy

Something large and bizarre, seemingly assembled from whatever was available – web threads, debris, and remnants – isn’t a creature of nightmares. It’s a decoy.

The real spider, much smaller (only about 5 mm), hides beneath the “abdomen” of its intimidating counterpart.

These clever decoys are crafted by spiders of the Cyclosa genus from the orb-weaver family (Araneidae). Typically, the real spider positions itself on the edge of the web, subtly pulling on the silk threads. This causes the fake spider to move, creating the illusion of a living, menacing predator from afar.

The decoy itself is a masterpiece of recycling. Cyclosa spiders construct it from leaf fragments, leftover egg sacs, and the desiccated bodies of previous victims. These creations serve as a diversion, tricking predators like paper wasps, birds, or lizards into attacking the decoy instead of the spider. This distraction gives the real spider precious time to escape.

There’s also a hypothesis that these web decorations attract more prey. Organic debris on the web hosts yeast-like fungi, which release chemicals that lure insects into the trap, increasing Cyclosa’s hunting success.
