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.

Best of the Web: Earth's glaciation periods may be triggered by large asteroid impacts - Yale

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."
