Digital modeling is playing a key role in the Commercial Engine Replacement Program (CERP) aimed at upgrading the U.S. Air Force's B-52 Bomber aircraft, Defense News reported.

Introduced in 1955, the B-52 strategic bomber needs no introduction and has been a critical part of the U.S. plans during the period of the Cold War and beyond. Last year, we reported how the B-52 bombers even took down fighter aircraft in Vietnam and how the U.S. Air Force plans to extend the life of this iconic aircraft by powering it with fresh new engines.

The world-first facility, which was developed by the Dalian Insitute of Chemical Physics (DICP) and Zhuhai Futian Energy Technology, hydrogenates carbon dioxide into green fuels, which could help to reduce the amount of carbon dioxide in the atmosphere.

In its statement, the DICP says "a technology that can selectively produce value-added hydrocarbon fuels with high energy density will provide a new route for promoting clean and low-carbon energy revolution."
Carbon dioxide hydrogenation technology for producing gasoline was originally proposed by DICP's Sun Jian GE Qingjie and WEI Jian in a 2017 paper published in the journal Nature Communications. The method uses metal catalysts to convert carbon dioxide into biofuels that are less harmful to the environment.

The B-21 Raider, the U.S. Air Force's dual-capable, penetrating strike bomber with stealth functions has moved a step closer to its first flight after the first aircraft moved out of the production facility, Air Force Magazine reported.

The futuristic fighter aircraft is called dual-capable since it is designed to deliver conventional as well as nuclear munitions. The Air Force awarded the engineering contract to Northrop Grumman in 2015 which completed the Critical Design Review in 2018. The supply chain issues arising from the pandemic may have plagued a lot of industries but the development and production of B-21 appear to have emerged unscathed.

David Bennett, the 57-year-old man who became globally known as the first human to receive a genetically modified pig's heart as a transplant has died in the hospital where he underwent the transplant and was recovering, according to a press release.⁠
⁠
Bennett was first admitted to the University of Maryland Medical Center (UMMC) in October last year with arrhythmia - the irregular beating of the heart, which in his case had become life-threatening. The doctors placed him on extracorporeal membrane oxygenation (ECMO), commonly known as a heart-lung bypass machine to keep him alive.⁠
⁠
A heart transplant was recommended, but with over 110,000 Americans on the waitlist to receive one, Bennett's time was running out. The clinical team suggested an alternative that had never been tried before.⁠

Women are born with all of the eggs they will ever have, unlike men, whose reproductive organs create millions of new sperm every day.
The quality of the chromosomes and DNA contained within each egg declines as women age, which is why the average 20-year-old has an 86 percent chance of becoming pregnant, whereas this drops to 36 percent for a 40-year-old.

That, however, may be about to change. Now, a team of researchers from Hebrew University in Israel has demonstrated that treating eggs with an anti-viral medicine can "reverse" the age of older eggs.
The “reverse aged” eggs apparently had chromosomes that look more like those from younger eggs, less damaged DNA, and they matured better in test tubes.
The development hasn't been tested against fertilization; however, it may provide hope for women over 40 wanting to be mothers by extending childbearing into middle age.

#Tesla has revealed that it will continue paying wages for at least three months if the Ukrainian employees are called to defend their country, CNBC reported after accessing an internal email.

Ahead of the Russian invasion, Ukrainian President Volodymyr Zelensky had called upon reservists to defend the country. It's been 15 days since the Russian onslaught started, and the Ukrainians have been on the defensive. While the U.S. and its allies have provided arms to the Ukrainian forces, as the invasion prolongs, more troops will be needed on the ground and Ukrainian citizens in other parts of the world may be called upon to join the defense.

If you have been wondering what the hype around metaverse is and just don't seem to get it, don't fret, you are not alone. Rather, you will find yourself in the company of 49 percent of Americans who were recently surveyed and were equally clueless about it.

Last year, Facebook made news when Mark Zuckerberg pivoted the company to begin building his vision of the metaverse. Following this move, a host of globally known names ranging from those in the fashion industry to sportswear, have taken the plunge into the metaverse and revealed plans of how they plan to expand their brands in this digital world. Last month, JP Morgan Chase became the first-ever bank in the metaverse as it looks to cash in on the $1 trillion market opportunity.

Elon Musk and his girlfriend Grimes welcomed a second child, a girl, in December 2021, the latter told culture magazine Vanity Fair in an interview and everybody is curious what her name will be.

The duo made headlines in 2020 when their firstborn was named X Æ A-12. While it had raised many eyebrows, the parents were quite open to sharing the rationale behind the name. While Musk shared it with the listeners of the Joe Rogan podcast, Grimes took to Twitter to reach out to anyone who was seeking an answer to the strange name.

The COVID-19 pandemic may have claimed roughly 18 million lives worldwide, more than three times the official death toll, according to a new estimate.
According to an analysis published in the Lancet by a team of health researchers, the higher figure represents a better approximation of the true worldwide casualty figure through the end of 2021.

The researchers say the true number of lives lost to the COVID-19 by 31 December 2021 was 18.2 million, which vastly outnumbers the 5.9 million deaths reported by various official sources for the same time span.

It's not life on Mars, but it does bear a slight resemblance.
NASA's Curiosity rover spotted a rock formation in the shape of a flower during its ongoing wanderings around the red planet's Gale Crater.
The flower-like formation is as small as a penny, a blog post from NASA reveals.

Curiosity captured the image of the rock formation on February 24 with the Mars Hand Lens Imager, which is located on its robotic arm. According to the U.S. space agency, the rock likely formed into its curious shape "in the ancient past when minerals carried by water cemented the rock."

For four decades, the U.S. Navy had not designed a new aircraft carrier. So, when it took up the task of building the Ford-class carriers, the Navy ensured that it was building the best aircraft carrier it had built so far. The first of its kind, USS Gerald Ford is now closer to taking to the battlefield with some of the most advanced technologies we have seen on a warship.

Honoring Gerald Ford who served the U.S. Navy during World War II, the first vessel of this class of aircraft carriers has been named after the 38th President of the United States. Instead of making incremental changes to its new warship, the Navy spent a good amount of money and time to bring on board the latest technological developments.

A new study is revealing that a reversal in the Earth's magnetic poles 42,000 to 41,000 years ago may have led to environmental crises that resulted in mass extinctions. The period is called the Laschamps excursion and the research used precise carbon dating obtained from ancient tree fossils to study its effects.
The team details how they created a precise radiocarbon record around the time of the "Laschamps geomagnetic reversal about 41,000 years ago from the rings of New Zealand swamp kauri trees."

"This record reveals a substantial increase in the carbon-14 content of the atmosphere culminating during the period of weakening magnetic field strength preceding the polarity switch." The team concluded that the "geomagnetic field minimum caused substantial changes in atmospheric ozone concentration that drove synchronous global climate and environmental" with their model investigating the consequences of this event.

Algae has such immense potential as a biofuel source that scientists have long been studying it for sustainable energy. They even created 3D printed artificial leaves out of algae to produce oxygen for our investigations of Mars.

Now, scientists from Texas A&M AgriLife Research are using artificial intelligence to break a new world record for producing algae as a reliable biofuel source, so that a greener and more economical fuel source for jet aircraft and other kinds of transportation could be achieved. The research project is conducted by Joshua Yuan, PhD., and funded by the U.S. Department of Energy Fossil Energy Office.
