Boldly going faster than the speed of light.
This summer, scientists discovered how to create a warp bubble in a lab, but that doesn’t mean warp drive is around the corner.
You may not see them coming, but the effects of climate change are starting to be felt in certain parts of the world. An example of this is the destruction of several coral reefs around the globe in recent years. As devastating as that sounds, it is only the prologue to a long list of potentially catastrophic events yet to arrive. In the long term, climate change threatens to eventually drive humans towards extinction. Therefore, while little steps, like planting more trees and turning out lightbulbs when not in use, are certainly useful, bigger steps are needed to fend off the devastating effects of climate change.
An internal combustion engine is one of the prime contributors to climate change-causing carbon emissions. Such engines produce large quantities of nitrogen oxide, carbon monoxide and other hydrocarbons that harm the environment and cause respiratory disorders in individuals. Due to these—and many more—reasons, electric vehicles, or EVs, need to replace the ones with traditional combustion engines.
EV owners can save about US$700 a year on fuel costs alone. Also, the maintenance expenses of EVs are lower than those of standard vehicles. So, owning EVs can help them save money and reduce their extreme reliance on fossil fuel, thereby slowing down its inevitable depletion from the earth. Additionally, EVs are incredibly efficient as they only consume approximately 25–40 kWh per 100 miles. Most importantly, EVs reduce CO2 emissions by nearly 178 million kg. What’s more, despite the high fuel efficiency and smaller carbon footprint, EVs can outperform vehicles with traditional combustion engines easily.
The new fiber battery is manufactured using novel battery gels and a standard fiber-drawing system. In a press release issued by MIT, MIT postdoc Tural Khudiyev noted that previous attempts to make batteries in fiber form were structured with key materials on the outside of the fiber. In the latest development, his system embeds the lithium and other materials inside the fiber, with a protective outside coating, creating a stable and waterproof version. He said it demonstrates that it’s possible to make a fiber battery that can be up to a kilometer long and highly durable, having many practical applications. As Khudiyev puts it, “there’s no obvious upper limit to the length. We could definitely do a kilometer-scale length.”
The 140-meter fiber produced can charge smartwatches or phones, with an energy storage capacity of 123 milliamp-hours.
“The beauty of our approach is that we can embed multiple devices in an individual fiber,” said former MIT postdoc Jung Tae Lee. The team had exhibited the integration of LED and Li-ion batteries in a single fiber, and Lee believes that more than three or four devices can be combined in such a small space in the future. “When we integrate these fibers containing multi-devices, the aggregate will advance the reaggregate of a compact fabric computer,” he added.
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.

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.

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.

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 outer space is terra incognita, a place yet unexplored or claimed, where everything is up for grabs, is more powerful today than ever before.
