The SARS-CoV-2 gene set remains unresolved, hindering dissection of COVID-19 biology. Comparing 44 Sarbecovirus genomes provides a high-confidence protein-coding gene set. The study characterizes protein-level and nucleotide-level evolutionary constraints, and prioritizes functional mutations from the ongoing COVID-19 pandemic.
O,.o! Circa 2018
We can produce very little antimatter and what we make is very difficult to store. These have been huge obstacles that have made antimatter propulsion many trillions of times beyond technological capabilities.
Positron Dynamics and Ryan Weed get around these issues by using isotopes of Krypton or sodium which naturally produce positrons (anti-electrons). They can use tiny amounts of Krypton isotopes to generation 100 billion to many trillions of positrons. They can also breed more of Krypton 79 isotopes by exposing Krypton 78 to neutrons.
Using a NASA NIAC study they have worked out more details and produced renderings of what the systems will look like.
Elon Musk makes fun of Joe Biden after the latter commented on the electric vehicles without mentioning the leader of this industry, Tesla.
Tesla has posted new jobs for its Tesla Bot team on its Careers page. Most of the Tesla Bot jobs are located in California except one located in Austin, Texas.
A few of the openings have been posted for quite some time. Tesla has been steadily posting jobs for the Tesla Bot team since the project was announced during Artificial Intelligence or AI Day back in August. Most of the new jobs seem to be related to software development for the Tesla Bot, hinting at the company’s progress with the humanoid robot.
The new Tesla Bot jobs are listed below with their responsibilities.
“These discoveries are essential for mankind to progress into the space age,” said lead research author Professor Sayaka Wakayama, a scientist at Japan’s University of Yamanashi.
There’s no need to discover life on Mars — not when we could possibly make our own.
Scientists have discovered that sperm can potentially survive on Mars for hundreds of years, meaning that humans could possibly reproduce on the Red Planet in the future.
“These discoveries are essential for mankind to progress into the space age,” lead research author Professor Sayaka Wakayama, a scientist at Japan’s University of Yamanashi, told the Daily Mail of the study.
Twitter’s e-commerce initiatives now include livestream shopping and Walmart will be the first retailer to test the new platform. Over the past year, Walmart has invested in live shopping by hosting events across social platforms like TikTok and YouTube, and soon it will debut Twitter’s first-ever shoppable livestream. On November 28, Walmart will kick off a Cyber Deals live event on Twitter, where users will be able to watch a live broadcast, shop the featured products and join the conversation around the event by posting tweets.
The livestream will begin at 7 PM ET on November 28, 2021, and will allow Walmart customers to shop from Twitter as well as a number of other platforms, including Walmart.com/live, and the retailer’s Facebook, Instagram, TikTok and YouTube accounts. Musician-turned-creator Jason Derulo will host the livestream, where he’ll introduce the audience to deals in electronics, home goods, apparel, seasonal décor and more during a 30-minute variety show. Surprise special guests will also drop in, says Walmart.
If we knew that a near-Earth asteroid (NEA) was headed for Earth could we deflect it?
Seeking to find out is the Double Asteroid Redirection Test (DART), a mission from NASA and the European Space Agency (ESA) to smash a 500kg spacecraft into binary asteroid 65,803 Didymos and its moonlet Dimorphos (also called, rather cutely, “Didymoon.”)
The idea is that by creating a “kinetic deflection” on Dimorphos it will ever so slightly change the trajectory of both objects.
And it could halve the transit time to Mars.
Pulsar Fusion Ltd., a nuclear fusion company based in the United Kingdom, has recently designed and successfully tested its first launch-capable, high-power chemical rocket engine.
From launching people and payloads into space, this engine could have numerous applications, but the company’s ultimate goal is to develop a hyper-speed propulsion engine using nuclear fusion technologies for interplanetary travel, with the first prototype expected in 2025.
And when this dream comes into fruition, it could cut the journey time to Mars in half.
Because global warming and its associated risks are here to stay.
Global warming is causing many physical risks such as droughts, wildfires, and floods. According to the Intergovernmental Panel on Climate Change, global warming is essentially irreversible, which means these dangers will keep coming up. Luckily, some countries have started planning ahead.
The Busan Metropolitan City of the Republic of Korea, the UN-Habitat, and OCEANIX have joined forces to build the world’s first prototype sustainable floating city in order to get ahead of physical risks.
“Sustainable floating cities are a part of the arsenal of climate adaptation strategies available to us. Instead of fighting with water, let us learn to live in harmony with it. We look forward to developing nature-based solutions through the floating city concept, and Busan is the ideal choice to deploy the prototype,” said in a statement the Executive Director of UN-Habitat, Maimunah Mohd Sharif.
As the population rises, more and more people are being pushed to coastal cities. However, these regions are notoriously susceptible to floods and hurricanes.
One of China’s biggest AI solution providers SenseTime is a step closer to its initial public offering. SenseTime has received regulatory approval to list on the Hong Kong Stock Exchange, according to media reports. Founded in 2014, SenseTime was christened as one of China’s four “AI Dragons” alongside Megvii, CloudWalk, and Yitu. In the second half of the 2010s, their algorithms found much demand from businesses and governments hoping to turn real-life data into actionable insights. Cameras embedded with their AI models watch city streets 24 hours. Malls use their sensing solutions to track and predict crowds on the premises.
SenseTime’s three rivals have all mulled plans to sell shares either in mainland China or Hong Kong. Megvii is preparing to list on China’s Nasdaq-style STAR board after its HKEX application lapsed.
The window for China’s data-rich tech firms to list overseas has narrowed. Beijing is making it harder for companies with sensitive data to go public outside China. And regulators in the West are wary of facial recognition companies that could aid mass surveillance.
But in the past few years, China’s AI upstarts were sought after by investors all over the world. In 2018 alone, SenseTime racked up more than $2 billion in investment. To date, the company has raised a staggering $5.2 billion in funding through 12 rounds. Its biggest outside shareholders include SoftBank Vision Fund and Alibaba’s Taobao. For its flotation in Hong Kong, SenseTime plans to raise up to $2 billion, according to Reuters.
