A team of MIT researchers recently created the first synthetic muscle actuator that can flex in multiple directions. This study opens the door for more capable soft robots and other advanced medical breakthroughs. Here’s how the team utilized a new 3D printing method, alongside specially made stamps, to grow synthetic muscles in the lab that can replicate the real thing.

Understanding Muscle Architecture and Movement

To understand why you can’t just make a motor that does what a muscle does, you first need to look at how your body operates. When you move your hand, there is a lot more going on than just your muscles pulling in a single direction. Many multidirectional skeletal muscle fibers form intricate patterns and are mounted at angles to produce the exact motions of the human body.

Our machines will be smart enough and eventually we will through intelligence enhancement.

For over a century, Einstein’s theories have been the bedrock of modern physics, shaping our understanding of the universe and reality itself. But what if everything we thought we knew was just the surface of a much deeper truth? In February 2025, at Google’s high-security Quantum A-I Campus in Santa Barbara, a team of scientists gathered around their latest creation — a quantum processor named Willow. What happened next would leave even Neil deGrasse Tyson, one of the world’s most renowned astrophysicists, in tears. This is the story of how a cutting-edge quantum chip opened a door that many thought would remain forever closed, challenging our most fundamental beliefs about the nature of reality. This is a story you do not want to miss.

Quantum computers have recently demonstrated an intriguing form of self-analysis: the ability to detect properties of their own quantum state—specifically, their entanglement— without collapsing the wave function (Entangled in self-discovery: Quantum computers analyze their own entanglement | ScienceDaily) (Quantum Computers Self-Analyze Entanglement With Novel Algorithm). In other words, a quantum system can perform a kind of introspection by measuring global entanglement nonlocally, preserving its coherent state. This development has been likened to a “journey of self-discovery” for quantum machines (Entangled in self-discovery: Quantum computers analyze their own entanglement | ScienceDaily), inviting comparisons to the self-monitoring and internal awareness associated with human consciousness.

How might a quantum system’s capacity for self-measurement relate to models of functional consciousness?

Key features of consciousness—like the integration of information from many parts, internal self-monitoring of states, and adaptive decision-making—find intriguing parallels in quantum phenomena like entanglement, superposition, and observer-dependent measurement.

One of the Holy Grails in cosmology is a look back at the earliest epochs of cosmic history. Unfortunately, the universe’s first few hundred thousand years are shrouded in an impenetrable fog. So far, nobody’s been able to see past it to the Big Bang. As it turns out, astronomers are chipping away at that cosmic fog by using data from the Atacama Cosmology Telescope (ACT) in Chile.

ACT measured light first emitted in the baby some 380,000 years after the Big Bang. According to the Consortium director Suzanne Staggs, that measurement opened the window to a time when the first cosmic structures were starting to assemble. “We are seeing the first steps towards making the earliest stars and galaxies,” she said. “And we’re not just seeing light and dark, we’re seeing the in high resolution. That is a defining factor distinguishing ACT from Planck and other, earlier telescopes.”

The clearer data and images from ACT are also helping scientists understand just when and where the first galaxies began to form. If the ACT data are confirmed, they represent the earliest baby picture of the universe, showing scientists what the seeds of galaxies looked like only a few hundred thousand years after the Big Bang.

The clearest and most precise images yet of the universe in its infancy—the earliest cosmic time accessible to humans—have been produced by an international team of astronomers.

Measuring light, known as the (CMB), that traveled for more than 13 billion years to reach a telescope high in the Chilean Andes, the new images reveal the universe when it was about 380,000 years old—the equivalent of hours-old baby pictures of a now middle-aged cosmos.

The research, by the Atacama Cosmology Telescope (ACT) collaboration, shows both the intensity and polarization of the earliest light after the Big Bang with unprecedented clarity, revealing the formation of ancient, consolidating clouds of hydrogen and helium that later developed into the first stars and galaxies.
