Altogether now ...



Biodiversity and climate change are two sides of the same coin and both must be addressed simultaneously if we are to save ourselves from a dark future of our own making. Rewild the world as per David Attenborough is the first thing to do now as without the natural world and its inherent link to biodiversity, civilization, as we know it, will be gone in a flash.

The Alien ... Earth style :)

Morays are Earth's version of the Alien as seen by the clip above. Awesome without question. :)

All bony fishes — those with skeletons made mostly of bone, rather than cartilage — have pharyngeal jaws in addition to their main jaws. Pharyngeal jaws lie behind the pharynx, or throat. They are smaller than the jaws in fishes' mouths and are used for gripping and piercing or crushing food, according to the Smithsonian National Museum of Natural History. 

But unlike most fishes' pharyngeal jaws, those in moray eels "are highly mobile" and can spring past the throat and into the morays' mouths, said Rita Mehta, an associate professor in the Department of Ecology and Evolutionary Biology at the University of California Santa Cruz (UCSC).

Long muscles pull morays' pharyngeal jaws forward to grasp prey and then slide it down their throats. (Image credit: Zina Deretsky, National Science Foundation (after Rita Mehta, UC Davis))

Our homegrown alien indeed. :)

20%


Global warming, the 900lb gorilla, is alive and well but we already know that, right?

Pine Island Glacier, one of the fastest-shrinking glaciers in Antarctica, hastened its slide into the sea between 2017 and 2020, when one-fifth of its associated ice shelf broke off as massive icebergs, a new study reveals.

The glacier sped up another time in recent history, between the 1990s and 2009, when warm ocean currents ate away at the underside of the ice shelf, destabilizing its structure and causing the glacier to accelerate toward open water, according to a 2010 report in the journal Geophysical Research Letters


GW acceleration enters primetime 24/7.

So glad I'm a guy save for the shaving bit. :)

 Google Uses AI to Design Computer Chips in Just 6 Hours

The last step in AI ascendency is the ability for said tech to design chips in just 6 hours versus the 6 month  process done by us. Warms the cockles of one's heart does it not?

Google says it has developed a way of using deep reinforcement learning (RL) to create computer chip floorplanning in just six hours — a complicated feat that typically requires humans months to achieve. 

The chips Google's AI develops are on par or superior than those humans can create, the team explained in its paper published in the journal Nature on Wednesday, June 9. 

In a first for one of its commercial products, Google's research is being used for the company's upcoming tensor processing unit (TPU) chips, which are optimized for AI computation.

So Google's AI method to design chips can eventually be used to improve and quicken the future development of AI.

Invisibilities


This pix, taken by yours truly, represents an object with great invisibilities as we see nothing of how the building was made, the raw materials used or the tech involved to erect said sky scraper in the first place and ... we haven's even discussed basic research in learning about what base materials needed to be known beforehand prior to building the construct in the first place. What's interesting about this is the fact the great invisibility applies to virtually everything in reality from dust motes to the universe as everything's connected at levels we will never fully understand.



Beginning in 2013, yours truly became fascinated by the fact infinities reside in finite space as shown by geniuses Georg Cantor, Karl Menger and Benoit Mandelbrot, among significant others, which became a series of blurbs in BRT that indirectly connects to the great invisibilities of everything known to exist in a entangled reality we will never fully understand. 

The eyes have it


The eyes have it. The larger the pupil, the smarter the person as per Scientific American.

It has been said that “the eyes are the window to the soul,” but new research suggests that they may be a window to the brain as well.

Our pupils respond to more than just the light. They indicate arousal, interest or mental exhaustion. Pupil dilation is even used by the FBI to detect deception. Now work conducted in our laboratory at the Georgia Institute of Technology suggests that baseline pupil size is closely related to individual differences in intelligence. The larger the pupils, the higher the intelligence, as measured by tests of reasoning, attention and memory. In fact, across three studies, we found that the difference in baseline pupil size between people who scored the highest on the cognitive tests and those who scored the lowest was large enough to be detected by the unaided eye.

Factoid ...

To be clear, pupil size refers to the diameter of the black circular aperture in the center of the eye. It can range from around two to eight millimeters. The pupil is surrounded by the colorful area known as the iris, which is responsible for controlling the size of the pupil. Pupils constrict in response to bright light, among other things, so we kept the laboratory dim for all participants.

As per Col. Nathan Jessup, Are we clear? :)

By a whisker :)


So many animals have whiskers. From cats to rats to seals, said mammals come equipped with a sensory aparatus us rubes don't have and ... researchers finally learned how whiskers actually work.

Rats, cats, and many other mammals have whiskers, which they typically use to sense their surrounding environment, akin to the sense of touch. But scientists have yet to precisely determine the means by which whiskers communicate that sense of touch to the brain. Now an interdisciplinary team at Northwestern University has come up with a new model to help predict how a rat's whiskers activate different sensory cells to do just that, according to a new paper published in the journal PLOS Computational Biology. Such work could one day enable scientists to build artificial whiskers as tactile sensors in robotics as well as shed further light on human touch.


Seems it's how they bend.

Hartmann et al. found that rat whiskers are most likely to bend in an "S" shape within the follicle when they touch an object. This bending then pushes or pulls on the sensor cells, triggering them to send touch signals to the brain. The same bending profile results regardless of whether the whisker brushes against an object or is externally touched. And both intrinsic muscle contraction and an increase in blood pressure can improve the tactile sensitivity of the system.

"Our model demonstrates consistency in the whisker deformation profile between passive touch and active whisking," said co-author Yifu Luo, a graduate student in Hartmann's lab. "In other words, the same group of sensory cells will respond when the whisker is deflected in the same direction under both conditions. This result suggests that some types of experiments to study active whisking can be done in an anesthetized animal."

How cool is that? :)

Since 1820 ...


This exquisite gif showing fluids moving at different speeds is both hypnotic and beguiling at the same time. Seems the very complex but reliable Naiver-Stokes equations are also as described in the Quanta article titled Mathematicians Find Wrinkle in Famed Fluid Equations

The Navier-Stokes equations capture in a few succinct terms one of the most ubiquitous features of the physical world: the flow of fluids. The equations, which date to the 1820s, are today used to model everything from ocean currents to turbulence in the wake of an airplane to the flow of blood in the heart.

While physicists consider the equations to be as reliable as a hammer, mathematicians eye them warily. To a mathematician, it means little that the equations appear to work. They want proof that the equations are unfailing: that no matter the fluid, and no matter how far into the future you forecast its flow, the mathematics of the equations will still hold. Such a guarantee has proved elusive. The first person (or team) to prove that the Navier-Stokes equations will always work — or to provide an example where they don’t — stands to win one of seven Millennium Prize Problems endowed by the Clay Mathematics Institute, along with the associated $1 million reward.




In lock step

 

In lock step happens if tipping points cascade to generate global changes in a given system, a scenario that may jump start a climate catastrophe for the ages if the Earth System Dynamics research rings true. 

Ice sheets and ocean currents at risk of climate tipping points can destabilise each other as the world heats up, leading to a domino effect with severe consequences for humanity, according to a risk analysis.

Tipping points occur when global heating pushes temperatures beyond a critical threshold, leading to accelerated and irreversible impacts. Some large ice sheets in Antarctica are thought to already have passed their tipping points, meaning large sea-level rises in coming centuries.

The new research examined the interactions between ice sheets in West Antarctica, Greenland, the warm Atlantic Gulf Stream and the Amazon rainforest. The scientists carried out 3m computer simulations and found domino effects in a third of them, even when temperature rises were below 2C, the upper limit of the Paris agreement.

The study showed that the interactions between these climate systems can lower the critical temperature thresholds at which each tipping point is passed. It found that ice sheets are potential starting points for tipping cascades, with the Atlantic currents acting as a transmitter and eventually affecting the Amazon.



We did this to ourselves.

Adding insult to injury ...



By 2045 ... , a BRT post describing man's reduced ability to reproduce, thanks to the ingestion of micro plastics and chemicals in our air and food, is a most disquieting read without question. The post in Scientific American discussing the dire impact of pesticides on the world's soils substantiates this concern without issue. 

Scoop up a shovelful of healthy soil, and you’ll likely be holding more living organisms than there are people on the planet Earth.





Any questions?

Consumption 101



Consumption 101 or how much more energy did the US consume in 2019 vs 2020? Seems quite a bit according to Lawrence Livermore Labs and the Department of Energy. 

To whit.

Consumption 101 indeed ...
