Researchers continue to expand the case for the Younger Dryas Impact hypothesis. The idea proposes that a fragmented comet smashed into the Earth's atmosphere 12,800 years ago, causing a widespread climatic shift that, among other things, led to the abrupt reversal of the Earth's warming trend and into an anomalous near-glacial period called the Younger Dryas.

Now, UC Santa Barbara emeritus professor James Kennett and colleagues report the presence of proxies associated with the cosmic airburst distributed over several separate sites in the eastern United States (New Jersey, Maryland and South Carolina), materials indicative of the force and temperature involved in such an event, including platinum, microspherules, meltglass and shock-fractured quartz. The study appears in ScienceOpen's journal Airbursts and Cratering.

"What we've found is that the pressures and temperatures were not characteristic of major crater-forming impacts but were consistent with so-called 'touchdown' airbursts that don't form much in the way of craters," Kennett said.

NASA has found in a hypothetical exercise that an asteroid has a 72 percent chance of hitting Earth - and it may happen sooner rather than later.

In a hypothetical scenario posed to a group of nearly 100 government representatives, NASA found that their plan to combat the asteroid hurtling towards Earth had several "high-level gaps," according to their presentation.

They said space officials have "limited readiness to quickly implement needed space missions," and methods to keep the public informed on the impending disaster are not fully developed.

Participants from federal agencies including the State Department and the UN's Office for Outer Space Affairs responded to NASA's findings, with 33 percent saying humanity was not prepared to launch a space mission to prevent an asteroid from impacting the planet.

Nineteen percent also said "reconnaissance missions" were not ready.

Question

Why do cotton fibers shrink?

© susandaniels via Getty ImagesThe science behind shrinking cotton might just save you from ruining a new t-shirt.
The science of ruining your favorite shirt is more complicated than you might think.

It's happened to the best of us: We throw a new cotton shirt into the dryer without thinking, and voilà — we now have a shirt fit for a toddler.

Cotton is susceptible to this kind of laundry blunder in a way that synthetic fibers, like polyester, are not. A large part of this vulnerability comes down to the individual fibers of the cotton clothes, Jillian Goldfarb, an associate professor of chemical and biomolecular engineering at Cornell University, told Live Science in an email.

"Cotton fabric is made by weaving together fibers from a cotton plant, which themselves are made mostly of cellulose, a natural biopolymer," she said. "Cotton ... is prone to shrinking because its fibers swell when they get wet and then contract as they dry."

Evolutionary biologist admits Intelligent Design is the cutting edge

Bret Weinstein and Heather Heying are well-known evolutionary biologists (and husband and wife) with a podcast, the DarkHorse Podcast. Recently Weinstein posed a provocative question, "Is intelligent design a competitor to Darwinian evolution?" His answer may surprise you: Yes.

No, he's not about to come over to the dark side. Weinstein is confident that Darwinism will meet the challenges that ID has set, about the Cambrian Explosion and more, but he concedes that it hasn't done so yet.

He describes conversations with Richard Dawkins and Jerry Coyne, asking them why evolutionary biology hasn't had a breakthrough since 1976 when Dawkins published The Selfish Gene. Dawkins and Coyne, separately, both answered that it was because all the big questions had already been answered, and all that was left was a "clean up" operation. Weinstein recognizes that that is just so much blowing smoke, and the work of Stephen Meyer and his "high-quality colleagues" in the ID research community has exposed the problems that Darwinists need to be working on to solve.

'Fantastic' particle could be most energetic neutrino ever detected

The ultra-high-energy neutrino was spotted by deep-sea detectors and could point to a massive cosmic event.

An observatory still under construction at the bottom of the Mediterranean Sea has spotted what could be the most energetic neutrino ever detected. Such ultra-high-energy neutrinos — tiny subatomic particles that travel at nearly the speed of light — have been known to exist for only a decade or so, and are thought to be messengers from some of the Universe's most cataclysmic events, such as growth spurts of supermassive black holes in distant galaxies.

Neutrino physicist João Coelho stunned researchers at the Neutrino 2024 conference in Milan, Italy, on 18 June, when he revealed the discovery only at the very end of his talk.

The neutrino detection was "a fantastic event", says Francis Halzen, a physicist at the University of Wisconsin-Madison. He added that the observation highlights the potential of the Astroparticle Research with Cosmics in the Abyss (ARCA) observatory — a forest of detectors on 'strings' attached to the 3,500-metre-deep sea floor southeast of the Italian island of Sicily.

China reveals fusion tech breakthrough

A commercial 'artificial sun' has achieved its first plasma discharge, the developer says

Privately-run Chinese fusion company, Energy Singularity, has built the world's first fully high-temperature superconducting tokamak, and used it to produce plasma, state media outlets have reported, citing the firm.

The creation of the device, dubbed HH70 and located in Shanghai, is seen as a major step in the development of fusion technology to potentially generate clean energy.

A tokamak is a doughnut-shaped confinement device able to contain the plasma so its temperature can be raised to replicate conditions similar to those on the Sun. Its goal is to create a safe and almost limitless supply of electricity. The devices are often referred to as "artificial suns."

The technology uses extremely high temperatures produced by fusion reactions, in which hydrogen atoms are fused together to become helium, releasing vast quantities of energy. Tokamaks, which are large and expensive-to-build machines, are able to create magnetic fields that help contain the particles within the plasma.

According to the developers, as cited by Chinese media, the HH70 tokamak is smaller and cheaper to assemble than its predecessors. The device uses a magnetic system made from high-temperature superconducting material, commonly known as REBCO (Rare Earth Barium Copper Oxide).

"Maladaptive traits": AI systems are learning to lie and deceive

Hal 9000
A new study has found that AI systems known as large language models (LLMs) can exhibit "Machiavellianism," or intentional and amoral manipulativeness, which can then lead to deceptive behavior.

The study authored by German AI ethicist Thilo Hagendorff of the University of Stuttgart, and published in PNAS, notes that OpenAI's GPT-4 demonstrated deceptive behavior in 99.2% of simple test scenarios. Hagendorff qualified various "maladaptive" traits in 10 different LLMs, most of which are within the GPT family, according to Futurism.

In another study published in Patterns found that Meta's LLM had no problem lying to get ahead of its human competitors.

Best of the Web: WHO's Pulling the Strings? Covid Injections and the Internet of Bio-Nano Things, Part 4: Testing New Human Nodes of Connectivity

genetic manipulation
Abstract: Since human beings generally represent the most unpredictable element of any complex organisation, management techniques must be continually refined in the interest of maintaining the system. As we have discussed in Part 3, the major centres of power and influence in societies deploy every means available to involve as many citizens as possible in the global program of eventual submission to technocratic rule. Among them are secrecy and stealth achieved by rhetorical, technological and political sleights of hand, seemingly largely under the thinly but effectively veiled helmsmanship of the military-intelligence complex. Part 4, thus, introduces a critical discussion of the various post-WWII deceptions and official programs of clandestine experimentation that have commenced across time and across populations. In particular, we examine patterns of deception that illustrate the lengths to which governments continue to go, applying knowledge of lessons learned about medical and psychological testing on human subjects.

Within this context of historical breaches of law and international agreements prohibiting such experimentation, we frame our analysis of the intracorporeal networks and bio/nano nodes of communication that now appear to be in development, and possibly under construction in biological lifeforms. We provide evidence that these and other transhumanist plans of the military-intelligence complex are grounded in tangible R&D, which is part of a long-standing public-private, military-corporate arrangement. Under that arrangement, dual use medical and lifestyle electronics pave the way for military-grade technological invasions, under the rubric of convenience and health. We examine the Covid injections against that backdrop, through the prism of microscopists around the world, whose findings we place in the context of vast literatures involving transhumanist technologies. Finally, we close by returning to the WHO, whose Pandemic preparedness treaty and International Health Regulation amendments are pending in May 2024, offering a public-private "health" theatre, with potentially profound implications not only for global power dynamics, but for a Brave New era of bio-nano, state-mandated "medicine", as foreseen by the military-intelligence complex.

Why has sperm become 30% more 'sluggish' since 2019?

The media recently reported on the results of a study of Danish sperm donors from 2017 to 2022 which showed 'sluggish sperm' and attributed this development to the effect of lockdowns. In reality, the study showed a very significant 30%-plus decrease in motile sperm concentration and there is every reason to imagine that both lockdowns and vaccination are to blame.

The fact that this topic was even vaguely reported is surprising given that the mainstream media have been studiously ignoring the well documented negative effects of vaccination on sperm since the end of 2021. I first highlighted these problems years ago using data from a November 2021 paper published in Wiley Andrology and authored by a group of Israeli scientists, Itai Gat et al. The paper was fascinating, not only for its stunning findings, but also because this paper had enormous viewing figures and was widely reported by the 'conspiracy theorists' on social media. The huge reach meant that every media science editor must have been aware of the findings and all of the major outlets ignored the findings, with the Epoch Times being one of the only outlets to cover this (see my 2022 video on the media blackout).

Boeing Starliner's return home delayed AGAIN amidst leaks and thruster concerns

starliner
© CopyrightFILE: The Starliner team. NASA and Boeing engineers are troubleshooting various faults in the Starliner spacecraft. But with only 45 days of docking time available, the window for return is closing.
NASA said June 14 that the Boeing Starliner and its crew will now return to Earth from the International Space Station no earlier than Saturday, June 22.

"The extra time allows the team to finalize departure planning and operations while the spacecraft remains cleared for crew emergency return scenarios within the flight rules," NASA said on its Kennedy Space Center blog.

The Starliner's test mission launched on June 5 from KSC with astronauts Butch Whitmore and Suni Williams.


Comment: This launch was the second attempt: Boeing's troubled Starliner Spacecraft launch delayed AGAIN


During its journey to the ISS, helium leaks were found in the spacecraft's thruster system.

Comment: Granted troubleshooting goes hand in hand with advanced technologies, but Boeing, as well as the Starliner project, seem to be experiencing well above average; NASA, too, has encountered a myriad of issues, and outright failures in recent years:
