anesthesia and the brain
Consciousness is one of the biggest mysteries of science, and new research shows anesthesia can erase the brain’s unique “fingerprint.”
Every person’s brain has a distinct pattern of activity, like a neural signature that defines thought, behavior, and awareness. Under anesthesia, these patterns vanish, leaving the brain in a uniform, disconnected state.
Using advanced imaging and EEG scans, scientists observed that anesthesia temporarily silences the brain’s communication networks.
Regions that normally interact to create self-awareness, memory, and perception no longer coordinate.
The result is a blank slate in terms of consciousness, even though the brain is still technically active.
This discovery helps explain why patients under anesthesia do not experience awareness or pain. It also provides scientists with a controlled way to study how consciousness emerges from neural activity.
By comparing awake and anesthetized brains, researchers can identify which networks are critical for awareness.
Understanding how the brain’s “fingerprint” disappears and reappears could improve anesthesia safety, help treat disorders of consciousness, and bring us closer to answering the age-old question:
what creates the sense of self?
The mind may be more fragile and more measurable than we ever imagined.

Chimps do think like humans!
A new study reveals that chimpanzees may think far more like humans than we ever realized. 🧠🐒

It seems amazing but we should have expected long ago. Only our ignorance and prejudice made us no believe. All primates are amazing! All animals, all lives are majestic!!
Researchers from UC Berkeley and Utrecht University discovered that chimps can reconsider their decisions when presented with stronger evidence, rather than stubbornly sticking to their first choice. This ability to rethink and adapt — once thought uniquely human — suggests a deeper level of cognitive flexibility in our closest relatives.
At the Ngamba Island Chimpanzee Sanctuary in Uganda, scientists tested chimps by hiding food in two boxes. When given a clearer clue later on, many chimps changed their choice, showing they could weigh new information against earlier guesses. Computational models confirmed that they were evaluating the strength of the evidence, not just reacting instinctively.

zepto = one trillionth of a billionth
In a groundbreaking physics experiment, scientists have successfully measured the shortest unit of time ever recorded, known as a zeptosecond, one trillionth of a billionth of a second. This unimaginably brief duration allows researchers to observe events at the subatomic level, such as the movement of electrons within atoms, with unprecedented precision.
Using advanced laser technology and ultrafast spectroscopy, the team was able to capture electron dynamics that were previously impossible to study. By measuring these fleeting moments, scientists gain insight into fundamental processes that govern matter and energy, opening new possibilities in quantum physics and material science.
Understanding phenomena on the zeptosecond scale could revolutionize fields like nanotechnology, electronics, and even chemical reactions, allowing engineers and researchers to manipulate atomic and molecular interactions with extraordinary accuracy. The achievement also pushes the boundaries of human knowledge, proving that time itself can be dissected and studied at scales far beyond everyday perception.
This milestone demonstrates not only the power of modern experimental physics but also the potential for future discoveries that could reshape technology and our understanding of the universe at its most fundamental level. Measuring a zeptosecond represents a leap forward in humanity’s quest to comprehend the intricacies of time and matter.
