Like many other living organisms, humans are born, survive, compete for resources, reach maturity, reproduce, take care of their young, sometimes the young of their young, continuously decline, and die. Evolution needs us for just two purposes – adapt and reproduce. But, unlike other species, humans are very conscious of their fate. Humans are very much aware that after reaching peak performance they will eventually grow old and die. We are very conscious of our fate after reaching peak performance – loss of function, frailty, and eventual loss of everything we worked so hard to earn.

We observe our parents, and other elderly around them, attend funerals, and understand that eventually we will get into this state. We are also very contempt with that fate as evolution made sure that. The more ambitious of us are trying to advance science, the rest seek refuge in religion, some in philosophy, some in accumulation of wealth, and some see the continuation of ourselves in our children. But despite the many technological advances transpiring in the laboratories all over the world, there is nothing we can do at this point to escape aging. There are diets, exercises, sleep, and supplements, but these provide very marginal benefits. We do not see 120+ old yoga and diet practitioners or marathon runners around. But these simple habits do help look younger longer. And many people that have very harmful habits like smoking but still diet and exercise to look younger.

Among thousands of the earliest survivors of COVID-19 in Wuhan, China, nearly half had at least one persistent symptom a full year after being released from the hospital, according to a new study published in JAMA Network Open.

The study followed up with 2,433 adult patients who had been hospitalized in one of two hospitals in Wuhan early on in the pandemic. Most had nonsevere cases, but a small number had severe COVID-19 and required intensive care. All of the patients were discharged between February 12 and April 10 2020, and the study follow-up took place in March of 2021.

Overall, 45 percent of the patients reported at least one symptom in that one-year follow-up. The most common symptoms were fatigue, sweating, chest tightness, anxiety, and myalgia (muscle pain). Having a severe case of COVID-19 increased the likelihood of long-lingering symptoms; 54 percent of the 680 severe cases reported at least one symptom after a year. But persistent symptoms were also common among the nonsevere cases, with 41.5 percent of 1,752 nonsevere cases reporting at least one symptom a year later.

A huge seismic event that started in May of 2018 and was felt across the entire globe has officially given birth to a new underwater volcano.

Off the eastern coast of the island of Mayotte, a gigantic new feature rises 820 meters (2,690 feet) from the seafloor, a prominence that hadn’t been there prior to an earthquake that rocked the island in May 2018.

“This is the largest active submarine eruption ever documented,” the researchers wrote in their paper.

As part of the launch of the new Loihi 2 chip, built on a pre-production version of Intel’s 4 process node, the Intel Labs team behind its Neuromorphic efforts reached out for a chance to speak to Mike Davies, the Director of the project. Now it is perhaps no shock that Intel’s neuromorphic effo…

Editor’s note, 6/28/21, 3:35 PM: The article was updated to clarify that Natrium features a sodium‐cooled fast reactor and not a type of molten salt reactor, as previously reported.

A nuclear power startup founded by Bill Gates has announced plans to build a new kind of nuclear reactor at a retiring coal plant in Wyoming.

This reactor will be the first real-world demonstration of the startup’s technology, which could help power the world — without warming the climate.

The videos are amazing.

After weeks and days of hardworking, SpaceX is gearing up to launch the Starship into orbit, the biggest test yet for the ship designed to send humans to Mars and beyond. The whole world, including us and you, are waiting for the promised day that will be covered in this video. Huge thanks to all these amazing SpaceX Artists. Please follow them and support them through Payoneer and Twitter.

StarshipBocaChica: The firm is preparing for the Starship’s first orbital flight, which will see the under-development rocket take off from the Starbase facility in Texas and land off the coast of Hawaii. On August 15 CEO Elon Musk declared via Twitter that the ship would be ready for the flight “in a few weeks, pending only regulatory approval.”
Musk first unveiled the predecessor to the ship in 2017 under the name “BFR,” SpaceX designed the fully reusable vessel to send over 100 tons or 100 people into space at a time. It can replace the firm’s existing rockets like the Falcon 9 and Falcon Heavy, while also taking on more ambitious goals like sending humans to Mars and beyond.
The ship uses liquid oxygen and methane as its fuel — meaning that, in theory, astronauts will be able to go to Mars, use the planet’s natural resources to generate more fuel, and use that to return home — or possibly venture out further. The flight will be around 90 minutes. The special thing about this start would be the fact that both stages would be in use – the Super Heavy Booster (BN4) and the Starship (SN20).
The booster would ignite its Raptor engines for two minutes and 49 seconds, come down in the Gulf of Mexico and attempt a landing. Musk confirmed on Twitter that the team has decided the booster will use 33 engines to offer 500,000 pounds of sea-level thrust. These engines will all be the same, except for the outer 20 which will lack some of the more complex controls.
SpaceX is not waiting around to start these missions. The firm is aiming to send the first humans to Mars by the mid-2020s, before establishing a self-sustaining city on Mars as early as 2050.
It could all start with the Starship — and at around 400 feet when paired with the Super Heavy booster that lifts it away from the Earth, this thing is huge. It greatly eclipses the Falcon 9 which measured less than 230 feet tall. It’s also powerful, with a liftoff thrust of 16 million pounds.
SpaceX announced at the launch of the plans that it “intends to collect as much data as possible during the flight to quantify the dynamics of entry and better understand what the spaceship is experiencing during such a flight that is extremely difficult to predict or accurately is to be replicated arithmetically.“
In comparison to the Saturn V, which is a rocket built by NASA; the Starship is taller than the Saturn V. It stands 394 feet (120 meters) tall, weighs 11,000,000 pounds (4,989,516.07 kilograms), and is made of stainless steel alloy.
According to SpaceX, Starship will be the most powerful launch vehicle ever developed and looks like this (SN15 Prototype).
WHAT IS THE PLAN?
In May 2,021 a document from the Federal Communications Commission revealed the plan for the first flight.
The ship will take off from the firm’s Starbase, Texas, launch facility. Around two minutes after liftoff, at 171 seconds, the Super Heavy booster will separate from the Starship. The ship will continue to complete a targeted landing around 60 miles northwest of the coast of Hawaii. The whole flight will last around 90 minutes.
SpaceX will not land the booster or the ship on land. The booster will land in the Gulf of Mexico, around 20 miles offshore, at 495 seconds or eight minutes after launch. The ship will complete a targeted powered landing in the sea.

What makes a truly world-changing invention? Of all the inventions of the 20th century just one could be said to have changed the world in such a way that it touches virtually everybody on the planet’s lives on a daily basis. It has enabled the most rapid development in technology in history and yet you cant see the vast majority of them directly and their individual job is just to switch on and off. This is the story of the MOSFET and how it changed the world.

Accounting and consulting firm PwC told Reuters on Thursday it will allow all its 40,000 U.S. client services employees to work virtually and live anywhere they want in perpetuity, making it one of the biggest employers to embrace permanent remote work.

The policy is a departure from the accounting industry’s rigid attitudes, known for encouraging people to put in late nights at the office. Other major accounting firms, such as Deloitte and KPMG, have also been giving employees more choice to work remotely in the face of the COVID-19 pandemic.

Elon Musk spoke with journalist Kara Swisher at the Code Conference on September 27 2021 for a wide-ranging conversation. In typical style, Musk made a number of predictions about the future, many of them having to do with his own portfolio of technology companies.
