SpaceX, Blue Origin, Virgin Galactic, and others are launching more rockets than ever. But the environmental impact and carbon emissions are poorly understood.
Self sustaining floating city for $200 million for 10,000 residents.
The world will soon have its first floating city by 2025 off the coast of South Korea’s Busan and will house 10,000 residents in a 75-hectare area.
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.

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.

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.”)
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.
