And it’s a hybrid mix of hydrogen and electric power.

Global mining company Anglo American is experimenting with hydrogen to power the giant mining trucks.

Mining trucks consume 35.3 gallons (134 liters) of diesel per hour with their enormous weight of around 220 metric tonnes and therefore emitting vast amounts of carbon dioxide into the atmosphere.

In order to reduce the mining industry’s carbon footprint, Anglo American is focused on mining trucks.

The company is collaborating with several partners, such as Engie, NPROXX, First Mode, Williams Advanced Engineering, Ballard, ABB, Nel, and Plug Power, to develop a hybrid mining vehicle, fueled with hydrogen and electricity.

But could it actually work?

Lighter-than-air spacecraft might one day help explore the clouds of Venus and investigate signs of ancient life on the planet.

Proposed in 2014 by Northrop Grumman, the Venus Atmospheric Maneuverability Platform (VAMP) project would deploy crewed inflatable aircraft from space to skim Venus’ upper atmosphere.

Now, a press release from West Virginia University reveals that engineers are developing software to allow spacecraft similar to these to navigate Venus’ atmosphere autonomously.

The power needed is so small, you could do this almost for free.’

Flying saucers are on their way to the Moon.

MIT scientists are developing a new concept for a circular hovering rover that levitates thanks to the moon’s natural electric field, a press statement reveals.

The new machines take advantage of the fact that airless bodies such as the moon and asteroids build up an electric field through direct exposure to the sun and their surrounding plasma. Such machines could be deployed on lucrative scouting missions on the surface of the moon as well as to nearby asteroids.

A new type of hovering spacecraft On a body as large as the moon, the surface charge is strong enough to power levitating machines — in fact, it has already been shown to levitate lunar dust up to a meter above the ground.

Now, Future Meat Technologies have announced that they have managed to produce cultivated chicken breast for just $7.70 per pound, (or $1.70 per 110-gram of chicken breast) down from under $18 per pound just six months ago. The move could soon see lab-grown meat making the rounds on supermarkets everywhere.

The firm also announced that it had raised $347 million in a Series B round of financing, meaning it will have plenty of money to continue on its mission to bring lab-grown meat to the masses.

“We are incredibly excited by the massive support of our global network of strategic and financial investors,” said in a statement Professor Yaakov Nahmias, founder and president of Future Meat. “This financing consolidates Future Meat’s position as the leading player in the cultivated meat industry, just three years after our launch. Our singular technology reduced production costs faster than anyone thought possible, paving the way for a massive expansion of operations. Our team will break ground on the first-of-its-kind, large-scale production facility in the United States in 2022.”

‘Hope for the best but prepare for the worst.’

The WHO has confirmed that, by December 19, the Omicron variant had spread to more than 89 countries. Many epidemiologists believe that Omicron will shortly become the dominant strain of COVID-19, replacing the delta variant (which is currently the dominant coronavirus variant). Compared to Delta, Omicron is capable of multiplying 70 times faster inside the human respiratory tract.

A recent report (Dec 10) from the UK’s Department of Health also indicates that household transmission of Omicron is around 3 times higher than for Delta. The World Health Organization (WHO) designated Omicron (aka. variant B.1.1.529) a variant of concern at the end of November, and within just a few weeks, it has led to increased case rates in a number of countries.

However, amidst the rapid spread of this new variant, there are still a large number of questions that need to be answered. Although Omicron appears to have a degree of vaccine escape, the exact extent of this is unknown, as is the ability of our existing vaccines to prevent severe illness and death in those infected, whether Omicron can also reinfect those with some immunity from previous infections with Delta, the risk of reinfection with Omicron, and the effectiveness of existing treatments.

It makes space travel look cheap.

Humans have been looking at the stars for millenia, but it was just over 30 years ago that the Hubble Space Telescope launched, and we started getting a really good look at what’s out there. Hubble was beset with more than a decade of setbacks before its launch in 1990. Then, just after taking its position orbiting Earth, astronomers realized that something wasn’t right. It took engineers another three years to fix a manufacturing error that had left one of the mirrors misshapen by one-millionth of a meter. Ultimately, that imperfection was enough to render the telescope’s mirrors effectively useless. The long wait was worth it, though. The Hubble enabled dozens of breakthroughs in astronomy. It also took beautiful pictures. A recent version of its famous “Hubble Deep Field” image includes galaxies that are 13 billion lightyears away, making them the farthest objects ever photographed.

NASA is scheduled to soon launch what it calls the “successor” to Hubble: the James Webb Space Telescope. Like the Hubble, the Webb telescope is also designed to take extraordinarily precise measurements of “Ultraviolet and visible light emitted by the very first luminous objects [and which] has been stretched or ‘redshifted’ by the universe’s continual expansion and arrives today as infrared light.” Webb will also study objects closer to home, such as planets and other bodies in our solar system with the aim of determining more about their origin and evolution. Webb will also observe exoplanets located in their stars’ habitable zones, to search for signatures of habitability, and to learn about their chemical compositions.

With many countries, companies and individuals intensifying their space exploration programs, questions about rights, ownership and the feasibility of manned space missions are coming to the fore of public debate.

In early 1,610, Italian astronomer and physicist Galileo Galilei wrote a letter to Cosimo de’ Medici—then Grand Duke of Tuscany—stating that he had observed for moons of Jupiter (which Galileo initially believed to be stars) using his improved telescope lens. Hoping to secure the grand duke’s patronage, Galileo proposed naming the bodies after Cosimo’s family, eventually calling them the “Medicea Sidera,” or the Medicean stars. (In the end, the moons were named for four lovers of the god Zeus: Io, Europa, Ganymede and Callisto.)

Galileo was not the first to claim stars in the name of people on Earth, and he was to be far from the last. Although the names of celestial bodies are now determined by the International Astronomical Union using a systematic naming system, the idea that is terra incognita, a place yet unexplored or claimed, where everything is up for grabs, is more powerful today than ever before.

Aging is a highly complex process with thousands of genes influencing our health, which poses a challenge for researchers looking to explain and target the underlying processes that lead to declining health. Researchers from the Babraham Institute’s Epigenetics research program have published a map of genetic interactions in C. elegans in iScience which can be used to identify new genes that influence lifespan and that have equivalent genes in humans.

Researchers use simple model organisms like the nematode worm C. elegans to gather information that can inform studies on human aging because many are shared or have counterparts in other species. However, there are some conceptual and that apply to the study of aging in model organisms. Dr. Casanueva, Group leader in the Epigenetics research program explains: “The way researchers usually study gene function is by disrupting its function and observing what happens. The disruption of some genes causes worms to live a very long-life. In this way, researchers have found the so-called ‘longevity-pathways.” However, the complexity underlying aging means that it is not enough to focus on individual genes. We need to study the overall organization of longevity by generating a systems-wide view.”

In collaboration with the physicist Marta Sales Pardo at University of Rovira i Virgili, Dr. Casanueva and her lab set out to cast a wider net when it comes to studying longevity genes. Together they created the largest network of gene regulatory interactions that are found in a long-lived type of C. elegans. In this network, the relationships between genes are represented by lines, and represented in different layers based on the flow of information between genes. The middle of the web represents the genes with the most influence, in this case, they receive complex input signals and de-code them, and connect to an output layer of genes. The researchers found that most key genes for longevity belong to transcription factors and metabolic genes.
