as newspapers today dont tend to hire children, a modern day Tintin would run a clickbait YouTube channel, except the clickbait is 100% real every single time

he starts off as an irritating conservative pundit at 14, meets Chang then leaves the think tank paying him and launches his own independent channel and blows up shortly after. Chang helps with video editing and managing his socials and they often chat on video calls between adventures. Haddock, his foster dad, has absolutely no knowledge of his earlier videos.

Wake up, babe. New MBARI species just dropped. 🤩 

MBARI researchers have discovered a remarkable new species of sea slug that lives in the deep sea. Bathydevius caudactylus swims through the ocean’s midnight zone and lights up with brilliant bioluminescence.

With a voluminous hooded structure at one end, a flat tail fringed with numerous finger-like projections at the other, and colorful internal organs in between, the team initially struggled to place this animal in a group. Because the animal also had a foot like a snail, they nicknamed this the “mystery mollusc.”

The team first observed the mystery mollusc in February 2000 during a dive with the institute’s remotely operated vehicle (ROV) Tiburon offshore of Monterey Bay at 2,614 meters (8,576 feet) deep.

They leveraged MBARI’s advanced and innovative underwater technology to gather extensive natural history information about the mystery mollusc. After reviewing more than 150 sightings from MBARI’s ROVs over the past 20 years, they published a detailed description of this animal.

What We Learned from Flying a Helicopter on Mars

The Ingenuity Mars Helicopter made history – not only as the first aircraft to perform powered, controlled flight on another world – but also for exceeding expectations, pushing the limits, and setting the stage for future NASA aerial exploration of other worlds.

Built as a technology demonstration designed to perform up to five experimental test flights over 30 days, Ingenuity performed flight operations from the Martian surface for almost three years. The helicopter ended its mission on Jan. 25, 2024, after sustaining damage to its rotor blades during its 72nd flight.

So, what did we learn from this small but mighty helicopter?

We can fly rotorcraft in the thin atmosphere of other planets.

Ingenuity proved that powered, controlled flight is possible on other worlds when it took to the Martian skies for the first time on April 19, 2021.

Flying on planets like Mars is no easy feat: The Red Planet has a significantly lower gravity – one-third that of Earth’s – and an extremely thin atmosphere, with only 1% the pressure at the surface compared to our planet. This means there are relatively few air molecules with which Ingenuity’s two 4-foot-wide (1.2-meter-wide) rotor blades can interact to achieve flight.

Ingenuity performed several flights dedicated to understanding key aerodynamic effects and how they interact with the structure and control system of the helicopter, providing us with a treasure-trove of data on how aircraft fly in the Martian atmosphere.

Now, we can use this knowledge to directly improve performance and reduce risk on future planetary aerial vehicles.

Creative solutions and “ingenuity” kept the helicopter flying longer than expected.

Over an extended mission that lasted for almost 1,000 Martian days (more than 33 times longer than originally planned), Ingenuity was upgraded with the ability to autonomously choose landing sites in treacherous terrain, dealt with a dead sensor, dusted itself off after dust storms, operated from 48 different airfields, performed three emergency landings, and survived a frigid Martian winter.

Fun fact: To keep costs low, the helicopter contained many off-the-shelf-commercial parts from the smartphone industry - parts that had never been tested in deep space. Those parts also surpassed expectations, proving durable throughout Ingenuity’s extended mission, and can inform future budget-conscious hardware solutions.

There is value in adding an aerial dimension to interplanetary surface missions.

Ingenuity traveled to Mars on the belly of the Perseverance rover, which served as the communications relay for Ingenuity and, therefore, was its constant companion. The helicopter also proved itself a helpful scout to the rover.

After its initial five flights in 2021, Ingenuity transitioned to an “operations demonstration,” serving as Perseverance’s eyes in the sky as it scouted science targets, potential rover routes, and inaccessible features, while also capturing stereo images for digital elevation maps.

Airborne assets like Ingenuity unlock a new dimension of exploration on Mars that we did not yet have – providing more pixels per meter of resolution for imaging than an orbiter and exploring locations a rover cannot reach.

Tech demos can pay off big time.

Ingenuity was flown as a technology demonstration payload on the Mars 2020 mission, and was a high risk, high reward, low-cost endeavor that paid off big. The data collected by the helicopter will be analyzed for years to come and will benefit future Mars and other planetary missions.

Just as the Sojourner rover led to the MER-class (Spirit and Opportunity) rovers, and the MSL-class (Curiosity and Perseverance) rovers, the team believes Ingenuity’s success will lead to future fleets of aircraft at Mars.

In general, NASA’s Technology Demonstration Missions test and advance new technologies, and then transition those capabilities to NASA missions, industry, and other government agencies. Chosen technologies are thoroughly ground- and flight-tested in relevant operating environments — reducing risks to future flight missions, gaining operational heritage and continuing NASA’s long history as a technological leader.

You can fall in love with robots on another planet.

Following in the tracks of beloved Martian rovers, the Ingenuity Mars Helicopter built up a worldwide fanbase. The Ingenuity team and public awaited every single flight with anticipation, awe, humor, and hope.

This is truly stiff competition for the worst case of willful false equivalence we've ever seen.

So, for those not aware: Ongoing embarrassment to gamers and the gaming industry, Mark Kern (former lead on FireFall), has been desperately trying to get Gamergate 2 going on X/Twitter... well after others have given up. If you need to get caught up on Mark, I recommend this video by documentary maker and experienced game developer, Dead Domain:

One of the latest fiascos in this mix has been the comparison of responses to character designs from Hades 2 (Aphrodite, left) and Stellar Blade (protagonist Eve, right). The post isn't by Mark, but is part of the general harassment campaign he's trying to lead.

If you're somehow not familiar with Aphrodite, she's the Ancient Greek goddess of love, lust and hot girl shit. It is absolutely perfect characterization for her to show up to a battle (or anything else) nude but for her hair teasingly covering the intimate parts of her body. But the buried lede here is, you don't fight her in Hades and nothing about Hades 2 indicates she'll fight there either, she just likes the aesthetic and has no reason not to indulge.

Stellar Blade will release on 26 April 2024, so we can't really give an informed discussion of her character. But what we do know is the studio head is the illustrator from Blade & Soul, Eve is described as being a member of "the 7th Airborne Squad" engaged in an "operation to reclaim the planet from the Naytiba", and the promotion material promises "an enthralling narrative filled with mature themes, mystery and revelation. Embrace the relentless pace, with no time to pause between moments where critical, story-changing decisions are made."

It's to be compared to games like Nier: Automata, Devil May Cry 5, Jedi: Fallen Order and Sekiro. And the screenshots look like this:

And yeah, unlike Bayonetta she's not supposed to be an unstoppable force of nature (and fashion) who is immune to self-doubt, she's supposed to be the scrappy underdog last survivor of her team.

Weird they gave her a costume that conveys... the opposite of literally everything they're supposed to be trying to tell you about her.

Watch Ethiopian wolves drink flower nectar, a first for a large carnivore

Pollen coating their muzzles suggests the endangered canids may act as furry pollinators.

With fewer than 500 individuals believed to be alive today, Ethiopian wolves (Canis simensis) are the world’s rarest wild canid and Africa’s most endangered carnivore. But when they’re not chowing down on rodents, these lanky, alpine wolf relatives have a bit of a sweet tooth: Researchers report this week in Ecology that the animals enjoy licking nectar from red hot poker flowers (Kniphofia foliosa, seen in the video above), documenting this behavior for the first time in a large predator...

What happens when you let a film nerd make an anime?

Fuuga Yamashiro (山代風我) joined Science Saru in 2017 as an Assistant Production Manager during production of "Night Is Short, Walk on Girl." He was essentially Studio Co-founder Masaaki Yuasa's secretary, but he worked his way up to assistant director on "Keep Your Hands off Eizouken" and finally got to direct his own first full Anime series, Dandadan.

Having worked so closely with one of the greatest living auteur directors, you might think he would share that overpowering individual creative influence, but as he has pointed out in interviews himself, it's much the opposite.

Instead of relying on his own creative voice, which he doesn't seem confident about in interviews, he literally collects techniques from his favorite movies, breaking them down into storyboards and adding them to his arsenal to re-contextualize later. And as you may be able to tell from watching Dandadan, his biggest influences aren't anime and manga, but live action film -- something he seems to have studied obsessively.

And when you compare the anime to the original manga (which itself is already filled with references to old movies and TV) subtle adaptation choices make the deft application of techniques borrowed from other storytellers very clear. Every choice is made for a reason and furthers the story being told in some way; nothing is there for no reason. like the simple, controlled camera pans and tilts that make the serpoian spaceship feel cold and sterile, or the crazywackysilly, un-predictable wide-angle camera movements that intrude on that cold sterile world when turbo granny shows up.

In one interview during the production of "Keep Your Hands off Eizouken" Yamashiro pulls out his notebook where he had collected all these techniques and gives an example:

"There's a technique called 'Dolly Zoom', which is a technique that changes the perspective of the background while keeping the size of the subject." […] "In 'Cult of Chucky,' which I saw recently, there is a scene in which a long passageway is filmed in telephoto, while a wheelchair moves forward. The character is 'getting closer, but the viewer feels farther away'. This is the kind of thing I collect." […] "I'd like to combine these things in various ways and do it in animation." (I took some liberties with this, the translation was pretty rough)

And sure enough, that exact same type of dolly zoom rears its head in Dandadan as Okarun sprints away from Turbo Granny and the mouth of the tunnel stretches impossibly into the distance.

It may seem counterintuitive to ascribe too much importance to the creative vision of one person who specifically talks about his own lack of strong creative vision, (and to be clear, he's far from the only person playing a major role) but I think it's precisely that encyclopedic knowledge of film techniques and that pragmatic, meticulous attitude that may have acted as a stabilizing force for Yuasa, and that also provides some needed structure to a ball of pure energy like Dandadan, while still preserving its essence and the eclectic influences that it wears on its sleeve.

Also, mad respect for using the seventh installment of the Child's Play franchise as your example of a dolly zoom instead of, like, Vertigo, Jaws, or Goodfellas.

This is just a sliver of what I talk about in this full video! A minuscule piece of the pie! Some tiny little crumbs for the peasants! So if you consider yourself worthy, go watch the whole video. I think it's good.

Uhh also reblog! I spent way too long on that intro animation, so I need it. Bad.

Fish size themselves up in a mirror to decide if they can win a fight

Cleaner wrasse use their reflection to build a mental image of their body size, which they use to compare themselves to rivals before picking a fight

Before deciding whether or not to fight another fish, cleaner wrasse check their own reflection in a mirror and size themselves up. Bluestreak Cleaner Wrasse (Labroides dimidiatus) are remarkably bright. These finger-sized coral reef fish were the first fish to pass the mirror test, a common assessment to see whether an animal recognises that the reflection is of its own body and not another animal. Researchers have now found that these wrasses use their likeness to construct a mental image of their body size, which they can compare to others...

Observations from both NASA’s James Webb and Hubble space telescopes created this colorful image of galaxy cluster MACS0416. The colors of different galaxies indicate distances, with bluer galaxies being closer and redder galaxies being more distant or dusty. Some galaxies appear as streaks due to gravitational lensing — a warping effect caused by large masses gravitationally bending the space that light travels through.

Like Taylor Swift, Our Universe Has Gone Through Many Different Eras

While Taylor's Eras Tour explores decades of music, our universe’s eras set the stage for life to exist today. By unraveling cosmic history, scientists can investigate how it happened, from the universe’s origin and evolution to its possible fate.

This infographic outlines the history of the universe.

0 SECONDS | In the beginning, the universe debuted extremely small, hot, and dense

Scientists aren’t sure what exactly existed at the very beginning of the universe, but they think there wasn’t any normal matter or physics. Things probably didn’t behave like we expect them to today.

Artist's interpretation of the beginning of the universe, with representations of the early cosmos and its expansion.

10^-32 SECONDS | The universe rapidly, fearless-ly inflated

When the universe debuted, it almost immediately became unstable. Space expanded faster than the speed of light during a very brief period known as inflation. Scientists are still exploring what drove this exponential expansion.

1 MICROSECOND | Inflation’s end started the story of us: we wouldn’t be here if inflation continued

When inflation ended, the universe continued to expand, but much slower. All the energy that previously drove the rapid expansion went into light and matter — normal stuff! Small subatomic particles — protons, neutrons, and electrons — now floated around, though the universe was too hot for them to combine and form atoms.

The particles gravitated together, especially in clumpy spots. The push and pull between gravity and the particles’ inability to stick together created oscillations, or sound waves.

Artist's interpretation of protons and neutrons colliding to form ionized deuterium — a hydrogen isotope with one proton and one neutron — and ionized helium — two protons and two neutrons.

THREE MINUTES | Protons and neutrons combined all too well

After about three minutes, the universe had expanded and cooled enough for protons and neutrons to stick together. This created the very first elements: hydrogen, helium, and very small amounts of lithium and beryllium.

But it was still too hot for electrons to combine with the protons and neutrons. These free electrons floated around in a hot foggy soup that scattered light and made the universe appear dark.

This animated artist’s concept begins by showing ionized atoms (red blobs), free electrons (green blobs), and photons of light (blue flashes). The ionized atoms scattered light until neutral atoms (shown as brown blobs) formed, clearing the way for light to travel farther through space.

380 THOUSAND YEARS | Neutral atoms formed and left a blank space for light

As the universe expanded and cooled further, electrons joined atoms and made them neutral. With the electron plasma out of the way, some light could travel much farther.

An image of the cosmic microwave background (CMB) across the entire sky, taken by ESA's (European Space Agency) Planck space telescope. The CMB is the oldest light we can observe in the universe. Frozen sound waves are visible as miniscule fluctuations in temperature, shown through blue (colder) and red (warmer) coloring.

As neutral atoms formed, the sound waves created by the push and pull between subatomic particles stopped. The waves froze, leaving ripples that were slightly denser than their surroundings. The excess matter attracted even more matter, both normal and “dark.” Dark matter has gravitational influence on its surroundings but is invisible and does not interact with light.

This animation illustrates the absorption of photons — light particles — by neutral hydrogen atoms.

ALSO 380 THOUSAND YEARS | The universe became dark — call it what you want, but scientists call this time period the Dark Ages 

Other than the cosmic microwave background, there wasn't much light during this era since stars hadn’t formed yet. And what light there was usually didn't make it very far since neutral hydrogen atoms are really good at absorbing light. This kicked off an era known as the cosmic dark ages.

This animation illustrates the beginning of star formation as gas begins to clump due to gravity. These protostars heat up as material compresses inside them and throw off material at high speeds, creating shockwaves shown here as expanding rings of light.

200 MILLION YEARS | Stars created daylight (that was still blocked by hydrogen atoms)

Over time, denser areas pulled in more and more matter, in some places becoming so heavy it triggered a collapse. When the matter fell inward, it became hot enough for nuclear fusion to start, marking the birth of the first stars!

A simulation of dark matter forming structure due to gravity.

400 MILLION YEARS | Dark matter acted like an invisible string tying galaxies together

As the universe expanded, the frozen sound waves created earlier — which now included stars, gas, dust, and more elements produced by stars — stretched and continued attracting more mass. Pulling material together eventually formed the first galaxies, galaxy clusters, and wide-scale, web-like structure. 

In this animation, ultraviolet light from stars ionizes hydrogen atoms by breaking off their electrons. Regions already ionized are blue and translucent, areas undergoing ionization are red and white, and regions of neutral gas are dark and opaque.

1 BILLION YEARS | Ultraviolet light from stars made the universe transparent for evermore

The first stars were massive and hot, meaning they burned their fuel supplies quickly and lived short lives. However, they gave off energetic ultraviolet light that helped break apart the neutral hydrogen around the stars and allowed light to travel farther.

Animation showing a graph of the universe’s expansion over time. While cosmic expansion slowed following the end of inflation, it began picking up the pace around 5 billion years ago. Scientists still aren't sure why.

SOMETIME AFTER 10 BILLION YEARS | Dark energy became dominant, accelerating cosmic expansion and creating a big question…?

By studying the universe’s expansion rate over time, scientists made the shocking discovery that it’s speeding up. They had thought eventually gravity should cause the matter to attract itself and slow down expansion. Some mysterious pressure, dubbed dark energy, seems to be accelerating cosmic expansion. About 10 billion years into the universe’s story, dark energy – whatever it may be – became dominant over matter.

An image of Earth rising in the Moon’s sky. Nicknamed “Earthrise,” Apollo 8 astronauts saw this sight during the first crewed mission to the Moon.

13.8 BILLION YEARS | The universe as we know it today: 359,785,714,285.7 fortnights from the beginning

We owe our universe today to each of its unique stages. However, scientists still have many questions about these eras.

Our upcoming Nancy Grace Roman Space Telescope will look back in time to explore cosmic mysteries like dark energy and dark matter – two poorly understood aspects of the universe that govern its evolution and ultimate fate.
