China to launch ‘Chinese Super Masons’ robot to build lunar bases with moon soil by 2028

Posted by in categories: biological, robotics/AI, space

The robot tasked with making bricks out of lunar soil will be launched during China’s Chang’e-8 mission around 2028.

With Artemis II set to launch on November 24, it is no surprise that science journals are buzzing with research on lunar regolith, building bases on the moon, and working with moon soil to grow plants… you get the drift.

A recent study in the journal Communications Biology described an experiment in which the moon soil samples collected during the Apollo missions were used to grow plants. And for the first time, an Earth plant, Arabidopsis thaliana, commonly called thale cress, grew and thrived in the lunar soil samples during the experiment.

Astronomers confirm presence of third protoplanet about 374 light years away

Posted by in categories: materials, space

The protoplanet was found surrounding HD 169,142, a star located 374 light years from our solar system.

Astronomers have caught a rare glimpse of a planet’s formation. This is only the third time scientists have discovered a protoplanet — an early stage in forming a planet, where cosmic material clumps in a disk surrounding newborn stars.

The observation of new protoplanet.

New Method To Measure Brain Fluid Pressure Developed

Posted by in categories: innovation, space

West Australian researchers have developed a breakthrough method to measure the brain fluid pressure in humans, which may reduce vision damage experienced by astronauts on long-haul space flights.

A cross-disciplinary team from the Lions Eye Institute and the International Space Centre at The University of Western Australia has developed a clever technique to measure the pressure in the brain fluid, the study was published in Nature in npj Microgravity.

Ultra-luminous X-ray sources defy Eddington limit and unlock universal secrets

Posted by in categories: particle physics, space

The mystery of ultra-luminous X-ray sources (ULXs) and their astonishing brightness has been partially unraveled through a recent study utilizing NASA’s NuSTAR.

Scientists have long been perplexed by ultra-luminous X-ray sources (ULXs), cosmic objects that emit about 10 million times more energy than the Sun and appear to break the Eddington limit — a physical boundary that determines the maximum brightness of an object based on its mass. In a groundbreaking study published in The Astrophysical Journal, researchers have confirmed that these extraordinary light emitters surpass the Eddington limit, potentially due to their strong magnetic fields.

Yuri Gagarin — the first human in space

Posted by in category: space

On 12 April 1961, cosmonaut Yuri Gagarin launched on Vostok-1 (Vostok-K rocket & Vostok 3KA space capsule) to become the first person to orbit the Earth, the first human in space. His flight lasted for 1 hour and 48 minutes.

Observatory discovers radio waves from distant planet in neighboring star system

Posted by in category: space

An astronomical discovery was made in New Mexico after an observatory called the Very Large Array picked up radio waves from a neighboring star system.

Scientists near Magdalena were looking for protective magnetic fields similar to Earth’s. The planet, titled YZ Ceti B, might be the first planet outside the solar system discovered with those properties, located just 12 light years away from Earth.

A Computational Quantum-Based Perspective on the Molecular Origins of Life’s Building Blocks

Posted by in categories: chemistry, computing, information science, quantum physics, space

Exciting.


The search for the chemical origins of life represents a long-standing and continuously debated enigma. Despite its exceptional complexity, in the last decades the field has experienced a revival, also owing to the exponential growth of the computing power allowing for efficiently simulating the behavior of matter—including its quantum nature—under disparate conditions found, e.g., on the primordial Earth and on Earth-like planetary systems (i.e., exoplanets). In this minireview, we focus on some advanced computational methods capable of efficiently solving the Schrödinger equation at different levels of approximation (i.e., density functional theory)—such as ab initio molecular dynamics—and which are capable to realistically simulate the behavior of matter under the action of energy sources available in prebiotic contexts.

NASA Confirms That Cosmic Object Is so Bright That It Defies Laws of Physics

Posted by in categories: physics, space

Astronomers have long debated the source of ULXs, chalking their brightness up to optical illusions. A new study confirms that they’re all that they appear.

Sarah Bakewell on Posthumanism, Transhumanism, and What it Actually Means to Be “Human”

Posted by in categories: computing, education, information science, space, transhumanism

Every time a person dies, writes Russian novelist Vasily Grossman in Life and Fate, the entire world that has been built in that individual’s consciousness dies as well: “The stars have disappeared from the night sky; the Milky Way has vanished; the sun has gone out… flowers have lost their color and fragrance; bread has vanished; water has vanished.” Elsewhere in the book, he writes that one day we may engineer a machine that can have human-like experiences; but if we do, it will have to be enormous—so vast is this space of consciousness, even within the most “average, inconspicuous human being.”

And, he adds, “Fascism annihilated tens of millions of people.” Trying to think those two thoughts together is a near-impossible feat, even for the immense capacities of our consciousness. But will machine minds ever acquire anything like our ability to have such thoughts, in all their seriousness and depth? Or to reflect morally on events, or to equal our artistic and imaginative reach? Some think that this question distracts us from a more urgent one: we should be asking what our close relationship with our machines is doing to us.

Jaron Lanier, himself a pioneer of computer technology, warns in You Are Not a Gadget that we are allowing ourselves to become ever more algorithmic and quantifiable, because this makes us easier for computers to deal with. Education, for example, becomes less about the unfolding of humanity, which cannot be measured in units, and more about tick boxes.
