Gazing out upon the apparently unchanging sea of stars around us, it's tempting to think of the Milky Way galaxy as static and everything within it as fixed and immutable.

While the timescales on which our galaxy moves often defies human experience, move it does indeed.

Not all of these dynamic processes are easy to see. Just a few years ago, scientists discovered a huge, wave-shaped structure extending some 9,000 light-years in length snaking along a spiral arm of the Milky Way, just 500 light-years from the Solar System at its closest point.

Comment: One wonders whether there's an energy coursing through the region causing the wave to move like that:

A patient implanted with Neuralink's brain technology can now control a computer mouse just by thinking, the company's founder Elon Musk said.

″[The] patient seems to have made a full recovery with no ill effects that we are aware of and is able to control the mouse, move the mouse around the screen just by thinking," Musk said in a Spaces session on social media platform X.

Neuralink is the billionaire's startup, which says it has developed a brain implant designed to help humans use their neural signals to control external technologies. The company aims to restore lost capabilities such as vision, motor function and speech.

A Yale-led research team has picked a side in the "Snowball Earth" debate over the possible cause of planet-wide deep freeze events that occurred in the distant past.

According to a new study, these so-called "Snowball" Earth periods, in which the planet's surface was covered in ice for thousands or even millions of years, could have been triggered abruptly by large asteroids that slammed into the Earth.

The findings, detailed in the journal Science Advances, may answer a question that has stumped scientists for decades about some of the most dramatic known climate shifts in Earth's history. In addition to Yale, the study included researchers from the University of Chicago and the University of Vienna.

Comment: As is increasingly the case, mainstream science is finally coming to conclusions that have long been put forth by authors and articles here on SOTT, but their finding has much more profound implications than they have yet to acknowledge: Also check out SOTT radio's:

For Darwin Day, Robert Shedinger calls Darwin's bluff

It's Darwin Day 2024, the birthday of Charles Darwin, and Discovery Institute Press has a new truth bomb for the occasion — Darwin's Bluff: The Mystery of the Book Darwin Never Finished. The book, by Robert Shedinger, Professor of Religion at Luther College in Decorah, Iowa, drags from Charles Darwin's closet a long overlooked skeleton devastating to the Darwinian mythology.

Tucked away in Darwin's surviving papers is a lengthy manuscript he never finished, The Origin of Species' oft-promised sequel on speciation he said would finally supply solid empirical evidence for the creative power of natural selection. He admitted such evidence was largely absent from the Origin, a work he repeatedly described as a "mere abstract." And yet Darwin soon abandoned his sequel, and without ever revealing this decision to his reading public.

The brightest quasar ever seen is powered by black hole that eats a 'sun a day'

The quasar, as bright as 500 trillion suns, has evaded astronomers for over 40 years because of its incredible luminosity.

A newly discovered quasar is a real record-breaker. Not only is it the brightest quasar ever seen, but it's also the brightest astronomical object in general ever seen. It's also powered by the hungriest and fastest-growing black hole ever seen — one that consumes the equivalent of over one sun's mass a day.

The quasar, J0529-4351, is located so far from Earth that its light has taken 12 billion years to reach us, meaning it is seen as it was when the 13.8 billion-year-old universe was just under 2 billion years old.

The supermassive black hole at the heart of the quasar is estimated to be between 17 billion and 19 billion times the mass of the sun; each year, it eats, or "accretes" the gas and dust equivalent to 370 solar masses. This makes J0529-4351 so luminous that if it were placed next to the sun, it would be 500 trillion times brighter than our brilliant star.

Best of the Web: Distinctly different brain organization patterns in women and men - Stanford Medicine

A new study by Stanford Medicine investigators unveils a new artificial intelligence model that was more than 90% successful at determining whether scans of brain activity came from a woman or a man.

The findings, to be published Feb. 19 in the Proceedings of the National Academy of Sciences, help resolve a long-term controversy about whether reliable sex differences exist in the human brain and suggest that understanding these differences may be critical to addressing neuropsychiatric conditions that affect women and men differently.

"A key motivation for this study is that sex plays a crucial role in human brain development, in aging, and in the manifestation of psychiatric and neurological disorders," said Vinod Menon, PhD, professor of psychiatry and behavioral sciences and director of the Stanford Cognitive and Systems Neuroscience Laboratory. "Identifying consistent and replicable sex differences in the healthy adult brain is a critical step toward a deeper understanding of sex-specific vulnerabilities in psychiatric and neurological disorders."

Comment: Other research has shown that understanding the differences between the sexes, as well as between races, is crucial in order to be able to provide the best possible healthcare.

And research highlighting these differences isn't new, as this 2018 article notes: How genetics is proving that race is not necessarily a social construct:
The differences between the sexes are far more profound than those that exist among human populations, reflecting more than 100 million years of evolution and adaptation. Males and females differ by huge tracts of genetic material - a Y chromosome that males have and that females don't, and a second X chromosome that females have and males don't.

Most everyone accepts that the biological differences between males and females are profound. In addition to anatomical differences, men and women exhibit average differences in size and physical strength. (There are also average differences in temperament and behavior, though there are important unresolved questions about the extent to which these differences are influenced by social expectations and upbringing.)

The regular 'Atlantic Circulation Collapse' story

-------
Atlantic Ocean
© tallbloke.wordpress.com
One of the many regular climate scare stories you can rely on is the one about failing currents in the Atlantic Ocean bringing cold climate chaos to Europe. It's one of the most favourite doomsday speculations, based on computer models pushed to the edge - but who cares, it's a good shock-horror story and it pops up regularly.

Actually we should care because it's well known that most people only register the top line of any news story — especially a climate disaster prediction - while they don't take-in or even read up on the context and the qualifications. That's when the headline becomes accepted as fact and takes its place as an undisputed example of the looming climate catastrophe.

For example see the tweets by Roger Hallam and John Simpson.

If some of the headlines in recent days are to be believed we are headed for a global climate disaster because of a slowdown in the circulation of the northern Atlantic Ocean predicted by computer models. But are we? No.

The real-life 'Day After Tomorrow': The Gulf Stream could collapse as early as 2025 - plunging Europe into a deep freeze, scientists warn

In the 2004 film The Day After Tomorrow, humanity is plunged into a nightmarish international storm that sends the planet into a new ice age. And although the blockbuster was consigned to the realms of sci-fi, the science behind the frightening scenario is true.

In a matter of years, melting glaciers could shut down the Gulf Stream - the system of currents that brings warmth to the northern hemisphere, experts say.

Without this additional heat source, average temperatures could drop by several degrees in North America, parts of Asia and Europe, and people would see 'severe and cascading consequences around the world'.

Scientists warn that an abrupt shutdown of Atlantic Ocean currents is looking more likely than ever, as computer simulations find a 'cliff-like' tipping point looming in the near future.
Europemap
In some parts of Europe, collapse of a large system of ocean currents called the AMOC could lead to a temperature decrease of more than 5.4°F (3°C) per 10 years.
The study authors, from Utrecht University in the Netherlands, don't know exactly when the collapse will happen, although a previous study put it as soon as next year.

'We are moving closer to the collapse, but we're not sure how much closer,' said lead author Rene van Westen, a climate scientist and oceanographer at Utrecht University. 'We are heading towards a tipping point.'

Comment: Melting glaciers? Arctic warming is part of Earth's normal 'ice age' cycle.

Audio cloning can take over a phone call in real time without the speakers knowing

man on cellphone
Generative AI could be listening to your phone calls and hijacking them with fake biometric audio for fraud or manipulation purposes, according to new research published by Security Intelligence. In the wake of a Hong Kong fraud case that saw an employee transfer US$25 million in funds to five bank accounts after a virtual meeting with what turned out to be audio-video deepfakes of senior management, the biometrics and digital identity world is on high alert, and the threats are growing more sophisticated by the day.

A blog post by Chenta Lee, chief architect of threat intelligence at IBM Security, breaks down how researchers from IBM X-Force successfully intercepted and covertly hijacked a live conversation by using LLM to understand the conversation and manipulate it for malicious purposes - without the speakers knowing it was happening.

"Alarmingly," writes Lee, "it was fairly easy to construct this highly intrusive capability, creating a significant concern about its use by an attacker driven by monetary incentives and limited to no lawful boundary."

'We are approaching the tipping point': Marker for the collapse of key Atlantic current discovered

The tipping point for the collapse of a key Atlantic Ocean current

Scientists have discovered a key warning sign before a crucial Atlantic current collapses and plunges the Northern Hemisphere into climate chaos.

The Atlantic Meridional Overturning Circulation (AMOC) carries warm water north from the Southern Hemisphere, where it releases heat and freezes. The freezing process concentrates salt in the non-frozen portion of the ocean water; this extra-saline water sinks, travels back south and picks up heat again, restarting the conveyor belt. (The Gulf Stream is part of this belt.)

This release of heat helps keep Europe, and to some extent North America, balmier than it otherwise would be. But sediment records over the past 100,000 years suggest that, at times, the AMOC has shut down abruptly, leading to major climate shifts over mere decades.

Comment: Comments:
1) The study mentioned in the article tested perhaps an earlier hypothesis expressed in:
Salty oceans provide early warning for climate change (June 2007)
Monitoring the saltiness of the ocean water could provide an early indicator of climate change. Significant increases or decreases in salt in key areas could forewarn of climate change in 10 to 20 years time. Presenting their findings at a recent European Science Foundation (ESF) conference, scientists predicted that the waters of the southern hemisphere oceans around South Africa and New Zealand are the places to watch.
2) The meaning of climate change, as the article uses it can be gathered from looking at what else the same publication has published, see this search result. Exploring one of the results, two days before the above mentioned study was published on February 9, 2024, there was a study published on February 7:
Addressing climate change with behavioral science: A global intervention tournament in 63 countries, they write in their abstract:
Effectively reducing climate change requires marked, global behavior change. However, it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. Here, we tested 11 expert-crowdsourced interventions on four climate mitigation outcomes: beliefs, policy support, information sharing intention, and an effortful tree-planting behavioral task. Across 59,440 participants from 63 countries, the interventions' effectiveness was small, largely limited to nonclimate skeptics, and differed across outcomes: Beliefs were strengthened mostly by decreasing psychological distance (by 2.3%), policy support by writing a letter to a future-generation member (2.6%), information sharing by negative emotion induction (12.1%), and no intervention increased the more effortful behavior — several interventions even reduced tree planting. Last, the effects of each intervention differed depending on people's initial climate beliefs. These findings suggest that the impact of behavioral climate interventions varies across audiences and target behaviors.
If "Effectively reducing climate change requires marked, global behavior change" then human activity is considered responsible, and the climate can be "fixed" by changing the behaviour of people. The politics of climate change work in favour or arguing for more control.

3) In the article, they write potentially as early as 2025
Scientists believe we could be veering towards this scenario once again — potentially as early as 2025 — as a result of climate change.
The link refers to an earlier news article in Live Science published July 25, 2023: Gulf Stream current could collapse in 2025, plunging Earth into climate chaos: 'We were actually bewildered'
The headline speaks of the Gulf Stream, but the paper mentions the AMOC:
Researchers have predicted the collapse of the AMOC could happen any time between 2025 and 2095 — far sooner than previous predictions, although not all scientists are convinced.
According the the current article: "The team found that about 25 years before the AMOC collapses, this flow reaches a minimum)." This could be interpreted to mean that If they come out next year and say the minimum was reached in 2024, then something drastic would happen in 25 years, or around 2050. However what the study actually says is "The FovS minimum occurs 25 years (9 to 41, 10 and 90% percentiles) before the AMOC tipping event." That is there is an interval of probability, with a 10 % chance it is less than 9 years and a 10 chance it is more than 41 years.

The abstract from the article in Nature Communications from July 2023 reads:
The Atlantic meridional overturning circulation (AMOC) is a major tipping element in the climate system and a future collapse would have severe impacts on the climate in the North Atlantic region. In recent years weakening in circulation has been reported, but assessments by the Intergovernmental Panel on Climate Change (IPCC), based on the Climate Model Intercomparison Project (CMIP) model simulations suggest that a full collapse is unlikely within the 21st century. Tipping to an undesired state in the climate is, however, a growing concern with increasing greenhouse gas concentrations. Predictions based on observations rely on detecting early-warning signals, primarily an increase in variance (loss of resilience) and increased autocorrelation (critical slowing down), which have recently been reported for the AMOC. Here we provide statistical significance and data-driven estimators for the time of tipping. We estimate a collapse of the AMOC to occur around mid-century under the current scenario of future emissions.
In other words the whole stick is that changes to the climate are pinned on human activity. What could be wrong with that?

4) The Earth exists in a cosmic environment that also undergoes changes:
For some links to this topic:

Adapt 2030 Ice Age Report: Interview with Laura Knight-Jadczyk and Pierre Lescaudron (2018)
Adapt 2030 Ice Age Report: Interview with Laura Knight-Jadczyk and Pierre Lescaudron (Part 2) (2018)

In short, 2025 is not likely when one looks into what the different models and statistical results actually say. However, those who argue for no climate change could be more off than those that hype it, if one considers the climate change agenda as a possible screen for earth changes, though most who promote the carbon footprint nonsense would be as blind to that possibility as those who claim all is normal.

7) The politics that trails "climate change" research
It can hard to separate politics from global warming science. According to the president of the European Central Bank be prepared to renounce banknotes, and accept changes to the way your bank is controlled, all for the sake of countering climate change:.


One way or the other, changes are likely, be they earth changes, climate changes, or changes to the political and financial systems. The official excuse for many political measures is global warming caused by human activity, as promoted by a stream of papers and panic stirring headlines, videos and news reports, but is there more to it than that? Looking around, there have been substantial disclosures and admissions about the human-alien interaction, to the point that in spite of efforts to suppress and some beating around the bush, there may in fact be something that could be of greater importance than whether or not human activity affects the climate over which. along with various wars, economic woes and "pandemics", societies are being distracted.
