NASA’s Juno Spacecraft ‘Hears’ Jupiter’s Moon​

Juno Principal Investigator Scott Bolton of the Southwest Research Institute in San Antonio has debuted a 50-second audio track generated from data collected during the mission’s close flyby of the Jovian moon Ganymede on June 7, 2021. Juno’s Waves instrument, which tunes in to electric and magnetic radio waves produced in Jupiter’s magnetosphere, collected the data on those emissions. Their frequency was then shifted into the audio range to make the audio track.


“This soundtrack is just wild enough to make you feel as if you were riding along as Juno sails past Ganymede for the first time in more than two decades,” said Bolton. “If you listen closely, you can hear the abrupt change to higher frequencies around the midpoint of the recording, which represents entry into a different region in Ganymede's magnetosphere.”

The ‘doomsday’ glacier is on the brink of collapse​

The Florida-sized Thwaites glacier in Antarctica, nicknamed the “doomsday glacier,” is already losing 50 billion tons of ice each year. That in itself accounts for around 4 percent of annual global sea level rise. But unpublished research shared at the American Geophysical Union fall meeting this week shows that the thinning ice shelf extending from Thwaites could shatter within the next three to five years. Behind Thwaites lies an even larger body of ice that, if the glacier melts, will be exposed to increasingly warm waters.

Rare and frightening footballfish washes up in California – again​

At first, the black blob spotted between rocks along the shores of San Diego this week was mistaken for a ball of tar. But as a concerned surfer approached, it became clear that this was something special.

The finned creature had a gaping underbite that revealed nightmarish spiny teeth, small black eyes, a tentacle-covered appendage and bulb protruding from its head.

Scientists at University of California San Diego’s Scripps Institution of Oceanography swiftly identified it as a Pacific football fish, a deep-sea dweller so rare that only 31 specimens have been found in more than a century since it was first discovered.

The rice of the sea: how a tiny grain could change the way humanity eats​

Growing up in southern Spain, Ángel León paid little attention to the meadows of seagrass that fringed the turquoise waters near his home, their slender blades grazing him as he swam in the Bay of Cádiz.

It was only decades later – as he was fast becoming known as one of the country’s most innovative chefs – that he noticed something he had missed in previous encounters with Zostera marina: a clutch of tiny green grains clinging to the base of the eelgrass.

His culinary instincts, honed over years in the kitchen of his restaurant Aponiente, kicked in. Could this marine grain be edible?

US Army Creates Single Vaccine Against All COVID & SARS Variants, Researchers Say ​

Within weeks, scientists at the Walter Reed Army Institute of Research expect to announce that they have developed a vaccine that is effective against COVID-19 and all its variants, even Omicron, as well as from previous SARS-origin viruses that have killed millions of people worldwide.

The achievement is the result of almost two years of work on the virus. The Army lab received its first DNA sequencing of the COVID-19 virus in early 2020. Very early on, Walter Reed’s infectious diseases branch decided to focus on making a vaccine that would work against not just the existing strain but all of its potential variants as well.

Astronomers Detect Up to 170 Rogue Planets Hurtling Aimlessly Through Space​

https://www.sciencealert.com/a-reco...ted-wandering-through-space-far-from-any-star

"Interstellar space is a graveyard of lost souls. Adrift far from any star, these planets float in the darkness like ghost ships in the night.

Catching sight of one requires patience, and a good eye. But a new approach based on tens of thousands of images collected by the European Southern Observatory's facilities has resulted in the identification of as many as 170 potential 'rogue' worlds in our corner of the galaxy.

"There could be several billions of these free-floating giant planets roaming freely in the Milky Way without a host star," says Hervé Bouy, an astronomer at the Laboratoire d'Astrophysique de Bordeaux in France.

Rogue planets all start their existence in the same swirls of gas and dust that give rise to a typical solar system, but some of these clouds of matter may be too small to form the star part of the system.

How many are virgin births, created without a star in sight, and how many are kicked out of their nest is hard to say. We just don't have enough information.

Being planets, they don't glow with the ferocity of a star. Detached from a solar system, they don't follow an orbital path that might otherwise identify them as an exoplanet."

A new 'Apollo moment': NASA prepares to launch James Webb Space Telescope​

https://www.nbcnews.com/science/space/james-webb-telescope-set-for-launch-nasa-rcna9489

"There's a period of time after the Big Bang, when the universe was in its infancy and the very first stars were blinking into existence, that remains one of the most mysterious chapters in the history of the cosmos.

If astronomers could study those chaotic, heady days of the early universe, they could begin to unravel how the cosmos evolved over more than 13 billion years. They might finally understand what extraordinary forces gave rise to stars, galaxies, black holes and planets — including worlds beyond Earth that may support life.

Yet even with the most sophisticated observatories in space and on the ground, scientists lacked the means to observe the oldest and most distant objects in the universe.

That is, until now.

NASA is set to launch into space humanity's largest and most powerful telescope, a $10 billion behemoth called the James Webb Space Telescope. The tennis court-sized observatory, slated to lift off Saturday from a European spaceport in French Guiana, will be able to see deeper into space and in greater detail than any telescope that has come before it.

"It's kind of a cliché to say that it’s going to change the course of astronomy, but it might very well do that," Marcia Rieke, an astronomer at the University of Arizona, said.

Rieke has spent the past 20 years leading the development of one of the Webb telescope's four main instruments, a specially designed infrared camera known as NIRcam. She said Webb could unlock mysteries of the early universe, from as far back as 100 million years after the Big Bang. It could also observe exoplanets with instruments sensitive enough to study their atmospheres, looking for potential biosignatures of alien life.

For all its potential benefits, the mission is also one of NASA's most daring."

LiFi is ready to go mainstream. Just the right hardware with enough bandwidth needed to power metaverse

Laser Broom is a futuristic device to aid in the fight against any hostile extraterrestrial species expected to be built in future.

Caseless ammunition is another technology currently under development and we might see new species of ammunition built which won’t require any case ever again whatsoever hence reducing the environmental impact.

This one is for the real geeks like the infamous theoretical physicist
Sheldon cooper. I mean theoretical physics is way ahead like a 4-10 centuries ahead in concept than the available technology to turn imagination into reality.

PlasmaBubble an impossible phenomenon like coldfusion is much ahead into becoming a reality

Plasma Bubbles​

The idea of the ‘plasma bubble,” originally suggested to resolve the pressure balance inconsistency [Pontius and Wolf, 1990] and evolved by subsequent studies [Chen and Wolf 1993, 1999], has been accepted as one of the possible mechanisms of the fast earthward flows.


If you like more geeky stuff, dm, it will be even more interesting to discuss the ideas of future concepts like LunarCrete, a physical block made from the material surface of the moon to be used for construction of base when we build and harness the resources from other planets.

Future is just about creating the right technology to transform dreams and imaginations into reality

Are We Living In A Simulation?​

"Even if we're not living in a simulation,
knowing what we know about the dangers of AI,
should we just give up on
developing machine super intelligence
before it turns against us,
like in The Matrix or Terminator
or 2001: A Space Odyssey or Westworld or Ex Machina?
I think it would be tragic
if we forever failed to do that.
I do think that transition however
will be associated with big risks,
including existential risks.
What we'll need to do is design AI systems
that are fundamentally on our side,
that share our values,
or that are aligned with human intentions."

Fascinating oceanographic research from the Discovery Gap: reconstruction of deep water paleocirculation in the Central and NE Atlantic oceanic basins.

https://www.sciencedirect.com/science/article/pii/S0967063721002181

7. Conclusions​

"In this work we have determined the hydrodynamic, morpho-structural and sedimentary characteristics of Discovery Gap and adjacent areas, decoded the key recent evolutionary stages and proposed a sedimentary and paleocirculation model for Discovery Gap with implications between the Central and NE Atlantic.

The constriction of sluggish abyssal bottom water by topography reinvigorates the corrosive Antarctic Bottom Water (AABW) enough to erode, rework and deposit sediment. The importance of NE–SW trending highs in controlling the flow of water through Discovery Gap is determined by the presence of erosion at the base of these highs with adjacent sheeted, plastered or mounded contourite drifts. The associations between pelagic, reworked pelagic and fine-grained contourite facies provide evidence for AABW variability and its intermittent influence in Discovery Gap during the Quaternary. Bottom current intensity was greatest during glacial–interglacial transitions, especially at Termination I, coeval to an increase in the sedimentation rate and dissolution of carbonate. Therefore, Quaternary climatic changes are a key controlling factor in deep-marine sedimentation.

This study provides new insights into deep water circulation in the Central–NE Atlantic and how the input of Antarctic water into the NE Atlantic has varied due to climate, amplified by the constriction of the deep marine gateway. Questions remain as to whether other gaps in the NE Atlantic demonstrate similar shifts in the intensity of AABW paleo-flow and if these various gaps were equally responsible for deep water exchange during deglacial periods. This study, therefore, highlights the importance of deep marine gaps in aiding the reconstruction of deep water paleocirculation not only in the Central and NE Atlantic but also in other oceanic basins."

COBOD AND CEMEX USE NEW CONCRETE THAT “GAINS SHAPE INSTANTANEOUSLY” TO 3D PRINT HOUSE IN ANGOLA​

"Mexican building material supplier CEMEX has developed a means of turning regular concrete into a more versatile aggregate, and deployed it to 3D print a low-cost home on the African continent.

Formulated alongside 3D printer manufacturer COBOD, this D.fab admixture-boosted blend is said to “gain shape instantaneously,” lending it significant construction lead time and cost-minimizing potential. Already, the companies have put their concrete to the test, working with contractor Power2Build to build Angola’s first 3D printed home, and they say it could now have much broader applications.

“To address the world´s affordable housing needs requires not only a technology that can build faster, but also materials that are as cost-effective as ordinary concrete,” said Ricardo Almeida, CEO of Power2Build. “With this solution, the strength and quality of concrete combined with the speed and automation of 3D printing, we can help solve the affordable housing crisis in Angola and elsewhere.”

https://3dprintingindustry.com/news...taneously-to-3d-print-house-in-angola-201633/

My 1st guess is they're using a new type of fast setting accelerant mixed into the concrete at the nozzle, to get the "gains shape instantly" effect without plugging up their equipment.

First 3-D printed Habitat home in US arrives​

The home is Habitat for Humanity's first 3D-printed home in the nation, according to a Habitat news release. ....

The concrete used in the house's 3D construction has many long-term benefits, such as the ability to retain temperature and withstand natural disasters, like tornadoes and hurricanes.

Stringfield's home also includes a personal 3D printer that will allow her to reprint anything she may need, "everything from electrical outlet to trim to cabinet knobs," Green told CNN.

While this is the first 3D home for Habitat for Humanity in the US, it certainly won't be the last. Green told CNN it hopes to continue partnering and developing the technology used with the printing.

"We would love to build more with this technology, especially because it's got that long-term savings for the homeowners," Green said.

Telling people to ‘follow the science’ won’t save the planet. But they will fight for justice​

People don’t need to know anything at all about climate science to know that a profound injustice has occurred here that needs to be righted. It’s not a scientific story, it’s a story of fairness: people with more power and money than you used information about climate change to shore up their own prospects and told you not to worry about it.

That story is backed up by not only the internal memos of various oil companies, and the discrepancies between those internal communicationsand what they were telling the public, but also by their patents. In 1973, Exxon secured a patent for an oil tanker that could easily navigate a melting Arctic. In 1974, Texaco was granted a patent for a mobile drilling platform in a melting Arctic. Chevron got a patent for its version of a melting-Arctic-ready drilling platform that same year. Shell was a bit behind; it got its melting-Arctic drilling platform design patented in 1983.

https://www.theguardian.com/commentisfree/2021/dec/28/follow-the-science-public-climate-crisis

I did not know about the patents granted to the oil companies in the 70s and 80s.
