Estimated to be 100–200 kilometers across, the unusual wandering body will make its closest approach to the Sun in 2031.

A giant comet from the outskirts of our Solar System has been discovered in 6 years of data from the Dark Energy Survey. Comet Bernardinelli-Bernstein is estimated to be about 1000 times more massive than a typical comet, making it arguably the largest comet discovered in modern times. It has an extremely elongated orbit, journeying inward from the distant Oort Cloud over millions of years. It is the most distant comet to be discovered on its incoming path, giving us years to watch it evolve as it approaches the Sun, though it’s not predicted to become a naked-eye spectacle.

In the yawning vacuum of intergalactic space, something large is lurking.

Not a galaxy, although it’s of a comparable size: A vast cloud of hot, faintly glowing gas, bigger than the Milky Way, in the space between galaxies congregating in a huge cluster.

Scientists believe this cloud may have been unceremoniously stripped from a galaxy in the cluster, the first gas cloud of this kind we’ve ever seen. Even more surprisingly, it hasn’t dissipated, but has remained clumped together for hundreds of millions of years.

Researchers aboard the ISS have announced the first successful use in space for a new technique for studying DNA repair in yeast. Astronauts aboard the space station have demonstrated a successful CRISPR/Cas9 genome editing method. An organism can suffer damaged DNA occurring during normal biological processes or as the result of environmental causes.

In both humans and animals, damaged DNA can lead to cancer. However, there are multiple natural strategies inside cells that allow damaged DNA to be repaired. NASA is working hard on studying DNA repair in space because astronauts traveling outside of the atmosphere have an increased risk of DNA damage due to ionizing radiation.

Until now, technological and safety obstacles have limited research into the issue. Now astronauts aboard the ISS have developed a new method for studying DNA repair in yeast cells that can be conducted completely in space. The process uses CRISPR/Cas9 genome editing technology to create precise damage in DNA strands to allow DNA repair mechanisms to be observed.

Concept I introduced long ago in TMP2 as the Inchworm orbital service robot is now being demonstrated by the ESA with the new Russian addition to the ISS.

It is much like a human arm. It has an elbow, shoulders and even wrists. The European Robotic Arm (ERA) is the first robot able to ‘walk’ around the Russian segment of the International Space Station.

Light yet powerful, the orbital arm has the ability to anchor itself to the Station and move back and forward by itself, hand-over-hand between fixed base-points. This space robot looks like a pair of compasses and has a length of over 11 m. When stretched, it could pass a football from a penalty spot to the goalkeeper.

Circa 2017

A new study by scientists at the University of Birmingham has revealed a group of cells that function as a ‘brain’ for plant embryos, capable of assessing environmental conditions and dictating when seeds will germinate.

A plant’s decision about when to germinate is one of the most important it will make during its life. Too soon, and the plant may be damaged by harsh winter conditions; too late, and it may be out-competed by other, more precocious plants.

In 1958, Ford showed the world a car like it had never seen before, one powered by a small nuclear reactor. The Ford Nucleon, as it was christened, was envisioned as a car capable of driving more than 5000 miles between fueling stops, appealing to a postwar fixation with convenience that has dominated American consumerism since. Like some other midcentury nuclear fantasies, though, the Nucleon never came to fruition, in part due to engineering problems we still struggle with to this day.

Before we examine why the Nucleon could never be, let’s get a better grasp of the car itself, starting with its utterly comical dimensions. Ford’s press materials envisaged the Nucleon stretching 200.3 inches long and 77.4 wide, making it as long as the new Ford Maverick compact pickup, but slightly wider. Its roof was said to measure just 41.4 inches high, making it less than an inch taller than the legendarily low-slung Ford GT40.

The ascendant industry is headlined by Beyond Meat and Impossible Foods, whose alt-meat burgers, chicken and sausage products have disrupted the $733 billion U.S. food manufacturing industry. That has prompted Tyson Foods, Purdue, Hormel, Cargill and other traditional meat producers to launch their own products in the category.

As consumers become increasingly comfortable eating faux-meat burgers that look, cook and taste like the real thing, a food-tech start-up backed by Jeff Bezos and Bill Gates is using fungus as the primary ingredient to create alt-meat foods.

Nature’s Fynd, based in Chicago, has raised $158 million in funding from investors including Bezos, Gates, and Al Gore. The company’s meatless breakfast patties and hamburgers, dairy-free cream cheese and yogurt, and chicken-less nuggets are scheduled to hit grocers’ shelves later this year.

A new class of drugs prevents the repair of damaged DNA. In recent animal studies, scientists found that it killed cancer cells with BRCA mutations.

Imagine you sit down and pick up your favorite book. You look at the image on the front cover, run your fingers across the smooth book sleeve, and smell that familiar book smell as you flick through the pages. To you, the book is made up of a range of sensory appearances.

But you also expect the book has its own independent existence behind those appearances. So when you put the book down on the coffee table and walk into the kitchen, or leave your house to go to work, you expect the book still looks, feels, and smells just as it did when you were holding it.
