Pulsar Fusion has begun construction of the world’s largest rocket engine, which will be fuelled by fusion. Within four years, the British company intends to create an 8-metre-long combustion chamber.

Here’s What We Know

The fusion engine will be based on a very hot plasma trapped inside an electromagnetic field. Now scientists are working on how to keep the plasma in the electromagnetic field. The announcement was made by James Lambert, CFO of the UK-based company.

A small selection of volunteers who were completely color blind can now faintly detect a splash of color following retinal gene therapy.

Following the trial by researchers in Israel, three adults and one child who could only sense brightness of light found that after gene therapy they were able to tell a red object apart from its darker background.

Achromatopsia is caused by defects in genes that control cone cells, our eyes’ color-sensors. The approximately 1 in 30,000 people affected see all the vibrant colors of the world as blurry shades of gray.

Long-lived fungi are the latest organisms to go under the microscope in search of new understandings as to why they don’t accrue life-limiting mutations, given their age.

Researchers at Wageningen University in the Netherlands set out to compare “the peculiarities” of multicellular growth in filamentous fungi. What they ended up with was a new hypothesis explaining how certain types of fungi keep a lid on freeloading mutations that accumulate in their thread-like mycelia; the root-like structures of fungal colonies.

The filaments of mushroom-forming fungi spend much of their long lives with two, separate nuclei, each containing one-half of a full set of chromosomes. Only in the gills of mushrooms moments before forming spores do the two haploid nuclei mesh together in a brief union to reproduce asexually.

In a study published recently in Advanced Intelligent Systems, researchers from Queen Mary University of London have made significant advancements in the field of bionics with the development of a new type of electric variable-stiffness artificial muscle that possesses self-sensing capabilities. This innovative technology has the potential to revolutionize soft robotics and medical applications.

Muscle contraction hardening is not only essential for enhancing strength but also enables rapid reactions in living organisms. Taking inspiration from nature, the team of researchers at QMUL’s School of Engineering and Materials Science has successfully created an artificial muscle that seamlessly transitions between soft and hard states while also possessing the remarkable ability to sense forces and deformations.

Dr. Ketao Zhang, a Lecturer at Queen Mary and the lead researcher, explains the importance of variable stiffness technology in artificial muscle-like actuators. “Empowering robots, especially those made from flexible materials, with self-sensing capabilities is a pivotal step towards true bionic intelligence,” says Dr. Zhang.

New glasses use sonar sensing technology and AI to allow users to control devices via silent, mouthed commands.

A powerful 7.2-magnitude earthquake struck near the Alaska Peninsula late Saturday.

Preliminary data placed the quake about 55 miles southwest of Sand Point, Alaska, the National Weather Service said. It had initially been measured at a magnitude of 7.4, the United States Geological Survey said on Twitter.

It struck at about 10:48 p.m. local time. In Kodiak, Alaska, sirens sounded late at night, according to a video posted on social media.

Swiss-Mile, a Swiss cutting-edge startup, created a robot-transformer that can perform a variety of tasks on it’s own.

For many, the word “crystals” conjures images of shimmering suncatchers that create a prism of rainbow colors or semi-transparent stones thought to possess healing abilities. But in the realm of science and engineering, crystals take on a more technical definition. They’re perceived as materials whose components – be it atoms, molecules, or nanoparticles –are arranged regularly in space. In other words, crystals are defined by the regular arrangement of their constituents. Familiar examples include diamonds, table salt, and sugar cubes.

Astronomers at the University of Sydney have shown that a small, faint star is the coldest on record to produce emission at radio wavelength.

The ‘ultracool brown dwarf’ examined in the study is a ball of gas simmering at about 425 degrees centigrade—cooler than a typical campfire—without burning nuclear fuel.

By contrast, the surface temperature of the sun, a nuclear inferno, is about 5,600 degrees.
