Will Technology Replace Biology? [Redux]
What would Hamlet have said at the edge of the technological event horizon? Check out this neo-Shakespearean take on the transhumanist dilemma.
Self-powered artificial synapse mimics human color vision
As artificial intelligence and smart devices continue to evolve, machine vision is taking an increasingly pivotal role as a key enabler of modern technologies. Unfortunately, despite much progress, machine vision systems still face a major problem: Processing the enormous amounts of visual data generated every second requires substantial power, storage, and computational resources. This limitation makes it difficult to deploy visual recognition capabilities in edge devices, such as smartphones, drones, or autonomous vehicles.
Interestingly, the human visual system offers a compelling alternative model. Unlike conventional machine vision systems that have to capture and process every detail, our eyes and brain selectively filter information, allowing for higher efficiency in visual processing while consuming minimal power.
Neuromorphic computing, which mimics the structure and function of biological neural systems, has thus emerged as a promising approach to overcome existing hurdles in computer vision. However, two major challenges have persisted. The first is achieving color recognition comparable to human vision, whereas the second is eliminating the need for external power sources to minimize energy consumption.
Scientists have discovered ‘third state’ between life and death
UNDATED (WKRC) — Scientists were diving into a mysterious biological phenomenon known as the “third state,” where cells of a deceased organism can adopt new functions after death, Popular Mechanics reported.
University of Washington biologist Peter Noble and Alex Pozhitkov have detailed this exploration in an article for The Conversation.
Their research highlighted the surprising resilience of xenobots and anthrobots, which can survive beyond the life of their host organism.
Quantum spirals: Programmable platform offers new ways to explore electrons in chiral systems
A new platform for engineering chiral electron pathways offers potential fresh insights into a quantum phenomenon discovered by chemists—and exemplifies how the second quantum revolution is fostering transdisciplinary collaborations that bridge physics, chemistry, and biology to tackle fundamental questions.
‘Link-bots’ can move, explore, cooperate without sensing or computation
Coordinated behaviors like swarming—from ant colonies to schools of fish—are found everywhere in nature. Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have given a nod to nature with a next-generation robot system that’s capable of movement, exploration, transport and cooperation.
A study in Science Advances describing the new soft robotic system was co-led by L. Mahadevan, the Lola England de Valpine Professor of Applied Mathematics, Physics, and Organismic and Evolutionary Biology in SEAS and the Faculty of Arts and Sciences, in collaboration with Professor Ho-Young Kim at Seoul National University. Their work paves new directions for future, low-power swarm robotics.
The new robots, called link-bots, are comprised of centimeter-scale, 3D-printed particles strung into V-shaped chains via notched links and are capable of coordinated, life-like movements without any embedded power or control systems. Each particle’s legs are tilted to allow the bot to self-propel when placed on a uniformly vibrating surface.
How the brain synchronizes itself with rhythmic stimuli
Our brain is adept at synchronizing with rhythmic sounds, whether it’s the beat of a song or the steady patter of rain. This ability helps us recognize and process sounds more effectively.
A research team led by the Max Planck Institute for Empirical Aesthetics (MPIEA) in Frankfurt am Main has shown that stimulation with weak electrical currents, known as transcranial alternating current stimulation (tACS), can influence this ability. The new study is published in the journal PLOS Biology.
The study builds on previous work showing that tACS can either enhance or suppress brain rhythms depending on how it’s timed with incoming sound. In order to investigate the interaction between electrical stimulation and brain rhythms, 50 participants took part in three experiments where they listened to noisy sounds and were asked to identify short, barely perceptible pauses. The researchers then transmitted electrical rhythms to the participants’ brains via electrodes placed on their scalps several times to see how this influenced their brain activity.
Rings of time: Unearthing climate secrets from ancient trees
Deep in the swamps of the American Southeast stands a quiet giant: the bald cypress (Taxodium distichum). These majestic trees, with their knobby “knees” and towering trunks, are more than just swamp dwellers—they’re some of the oldest living organisms in Eastern North America. Some have been around for more than 2,500 years, quietly thriving in nutrient-poor, flooded forests where most other trees would wither.
But life isn’t easy for these ancient trees. They’re under siege from a variety of threats: rising seas, insect infestations, wildfires and increasingly erratic weather patterns. Unlike most animals, trees generally don’t die of old age—they succumb to the stresses around them.
A study by Florida Atlantic University, in collaboration with Lynn University, the University of Georgia, the Georgia Department of Natural Resources, and the Georgia Museum of Natural History, reveals how dramatic shifts in climate can have long-lasting effects on even the toughest, most iconic trees—and offers a glimpse into the powerful forces that shape our natural world.
