Possible Eoarchean Records of the Geomagnetic Field Preserved in the Isua Supracrustal Belt, Southern West Greenland

(24 April 2024)

The preservation of a temperate climate and liquid water on early Earth depends critically upon the strength of the magnetosphere (Sterenborg et al., 2011; Tarduno et al., 2014). Recent atmospheric escape models have suggested that both weak (<10 μT) and strong (>1 mT) magnetic fields could substantially enhance atmospheric escape under present-day solar wind conditions via the polar wind or cusp escape, respectively (Gronoff et al., 2020; Gunell et al., 2018; Lundin et al., 2007). During the Archean, the Sun was rotating faster, generating a stronger stellar dynamo and therefore the solar wind was more intense than today (Vidotto, 2021). An increased solar wind strength causes greater interaction with the upper atmosphere and greater escape of ions assuming a constant level of protection from Earth‘s magnetosphere. Previous magnetohydrodynamic simulations have suggested that if Earth‘s magnetic field was half its present day strength 3.5 Ga ago, the area of the polar cap (the area containing open dipolar magnetic field lines, allowing atmospheric escape via the polar wind) could increase by up to 50% (Sterenborg et al., 2011).

A global environmental crisis 42,000 years ago

(19 Feb 2021)

Do terrestrial geomagnetic field reversals have an effect on Earth‘s climate? Cooper et al. created a precisely dated radiocarbon record around the time of the Laschamps geomagnetic reversal about 41,000 years ago from the rings of New Zealand swamp kauri trees. This record reveals a substantial increase in the carbon-14 content of the atmosphere culminating during the period of weakening magnetic field strength preceding the polarity switch. The authors modeled the consequences of this event and concluded that the geomagnetic field minimum caused substantial changes in atmospheric ozone concentration that drove synchronous global climate and environmental shifts.

(…)

We precisely characterize the geomagnetic reversal and perform global chemistry-climate modeling and detailed radiocarbon dating of paleoenvironmental records to investigate impacts. We find that geomagnetic field minima ~42 ka, in combination with Grand Solar Minima, caused substantial changes in atmospheric ozone concentration and circulation, driving synchronous global climate shifts that caused major environmental changes, extinction events, and transformations in the archaeological record.

Erdmagnetfeld: Polwanderung veränderte das Weltklima

Ungefilterte Strahlung aus dem Weltraum zerriss Luftpartikel in der Erdatmosphäre, trennte Elektronen ab und emittierte Licht. Diese ionisierte Luft brutzelte die Ozonschicht weg, heißt es in einer Presseaussendung zur Studie. In Folge dürften überall auf dem Globus Polarlichter aufgetaucht sein, nicht nur rund um den geographischen Nord- und Südpol wie heute. (…)

Das Erdmagnetfeld schwächelt bereits seit rund 2.000 Jahren wieder. Verglichen mit den ersten direkten Messungen vor 170 Jahren wurde eine Abschwächung um neun Prozent festgestellt, im Bereich des Südatlantiks sogar um dreißig Prozent.

Endonuclease fingerprint indicates a synthetic origin of SARS-CoV-2

(20.10.2022)

The goal of this paper is to address the question whether SARS-CoV-2 originated from an animal-to-human spillover or from experiments performed in a laboratory. In the latter scenario, it is possible that evidence exists for manipulation of the viral genome by common laboratory techniques. SARS-CoV-2 is a large RNA virus. To create infectious versions of CoVs, the entire 30kb RNA genome is reconstructed in DNA by in vitro genome assembly (IVGA). IVGA has been used to create reverse genetic systems for modified and chimeric RNA viruses for more than 20 years (Yount et al, 2000). Most importantly, IVGA methods can leave genetic fingerprints, and we find those fingerprints in the genome of SARS-CoV-2.

Financing Putin’s war: Fossil fuel exports from Russia in the first six months of the invasion of Ukraine

Key findings include:

Fossil fuels continue to fill Kremlin’s war chest, due to high prices

– Russia earned EUR 158 billion in revenue from fossil fuel exports in the first six months of the war (February 24 to August 24). The EU imported 54% of this, worth approximately EUR 85 billion.

– Fossil fuel exports have contributed approximately EUR 43 billion to Russia’s federal budget since the start of the invasion, helping fund war crimes in Ukraine.

– The largest fossil fuel importer was the EU (EUR 85.1bln), followed by China (EUR34.9bln), Turkey (EUR10.7bln), India (EUR6.6bln), Japan (EUR2.5bln), Egypt (EUR2.3bln, and South Korea (EUR2bln).

– Surging fossil fuel prices mean that Russia’s current revenue is far above previous years’ level, despite the reductions in this year’s export volumes.

Die Meta-Studie der Johns-Hopkins-Universität bestätigt nun das Versagen der Bundesregierung, das für aufmerksame Beobachter schon vor über einem Jahr klar war. Besonders pikant: Das von einem Merkel-Vertrauten geleitete Bundesverfassungsgericht hatte die Ausgangssperren, Kontaktbeschränkungen und Schulschließungen Ende 2021 noch als „wirkungsvoll“ und damit verfassungsgemäß eingestuft – offensichtlich bar jeder wissenschaftlichen Evidenz.

Brisant: Gravierende Mängel in der Zulassungsstudie von BioNTech/Pfizer

Indem man die anderen Zeugen und das Indizien-Material wie Fotos und Emails ignorierte, wurde aus den in Texas festgestellten Mängeln die lokale „Schlamperei“ (ntv, t-online, Focus, RND) eines „Subunternehmens“ (Spiegel, ntv, t-online, Tagesspiegel, RND) von Pfizer/BioNTech. Auf die Effektivität und die Sicherheit des Vikzins wirke sich die texanische Nebengeschichte nach Ansicht von „Experten“ nicht aus.

Researchers find a higher than expected risk of myocarditis in young men after full vaccination.

(Oct. 6, 2021)

Males between 16 and 29 years of age have an increased risk of developing heart problems after receiving a second dose of coronavirus vaccines made by Pfizer-BioNtech or Moderna, according to a large new analysis published on Wednesday in the New England Journal of Medicine.

The study, conducted in Israel, estimated that nearly 11 of every 100,000 males in that age group developed myocarditis, inflammation of the heart, a few days after having been fully vaccinated. That figure is higher than most earlier estimates.

(2021 Sep 30)

At the country-level, there appears to be no discernable relationship between percentage of population fully vaccinated and new COVID-19 cases in the last 7 days (Fig. 1). In fact, the trend line suggests a marginally positive association such that countries with higher percentage of population fully vaccinated have higher COVID-19 cases per 1 million people. Notably, Israel with over 60% of their population fully vaccinated had the highest COVID-19 cases per 1 million people in the last 7 days.

Comparing SARS-CoV-2 natural immunity to vaccine-induced immunity: reinfections versus breakthrough infections

(August 25, 2021)

Results:

SARS-CoV-2-naïve vaccinees had a 13.06-fold (95% CI, 8.08 to 21.11) increased risk for breakthrough infection with the Delta variant compared to those previously infected, when the first event (infection or vaccination) occurred during January and February of 2021. The increased risk was significant (P<0.001) for symptomatic disease as well. When allowing the infection to occur at any time before vaccination (from March 2020 to February 2021), evidence of waning natural immunity was demonstrated, though SARS-CoV-2 naïve vaccinees had a 5.96-fold (95% CI, 4.85 to 7.33) increased risk for breakthrough infection and a 7.13-fold (95% CI, 5.51 to 9.21) increased risk for symptomatic disease.

Adenovirus vector vaccination reprograms pulmonary fibroblastic niches to support protective inflating memory CD8+ T cells

(15.07.2021)

The ultimate goal of T cell-based vaccination strategies is the induction of long-term immunological protection via effector memory T cells1. Adenovirus (Ad) vector-based vaccines using the backbone of human Ads have been shown in clinical studies
to be highly immunogenic with induction of specific antibody and/or T cell responses to viral or cancer antigens. However, pre-existing anti-Ad antibodies in vaccinated individuals reduces immunogenicity and efficacy of vaccines based on human Ads, which led to the development of non-human vectors based on chimpanzee viruses. Chimeric Ad vectors have been shown to induce long-lived T cell responses against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and to generate polyfunctional central and effector memory T cells against hepatitis C
virus.

(…)

Results

Targeting of human fibroblasts by Ad vectors. Human Ads were first described as cytopathogenic agents isolated from human adenoid tonsils28. Here, we used sliced tissue cultures from human
palatine tonsils to assess the cellular tropism of green fluorescent protein (GFP)-expressing Ad vectors (Extended Data Fig. 1a). Both HuAd5-GFP and chimpanzee (Ch)AdOx1-GFP vectors readily transduced cells in the tissue slides, with PDPN+CD45− cells most
frequently expressing the GFP transgene (Fig. 1a,b). Next, we compared side-by-side the susceptibility to infection with recombinant Ad vectors of short-term cultured tonsillar stromal cells (TSCs) and peripheral blood mononuclear cells (PBMCs). Both ChAdOx1-GFP (Fig. 1c,d) and HuAd5-GFP (Fig. 1e,f ) efficiently transduced TSCs following an incubation of 3 h, while the transduction rate of PBMCs remained low. Even at the high multiplicity of infection (MOI) of 1,000 particles per cells, less than 2% of the hematopoietic cells were GFP-positive.

JAB ‚FOR LIFE‘: AstraZeneca Covid vaccine gives powerful protection that may last a lifetime, study finds

(15.07.2021)

Scientists from Oxford and Switzerland, writing in journal Nature, say T-cell protection is a “key feature” of adenovirus vaccines like the Oxford and J&J jabs.

Researcher Prof Burkhard Ludewig, of Cantonal Hospital in Switzerland, said: „The T-cells that come from these cellular training camps appear to have a very high level of ‘fitness’.

“Adenoviruses have co-evolved with humans over a very long time, and learned a lot about the human immune system in the process.

PCR-Tests ausgewertet: Ergebnisse allein ungeeignet als Grundlage für Pandemie-Maßnahmen

(18.06.2021)

Forschende der Medizinischen Fakultät der UDE weisen im renommierten Journal of Infection* darauf hin, dass die Ergebnisse von RT-PCR-Tests allein eine zu geringe Aussagekraft haben, um damit Maßnahmen zur Pandemiebekämpfung zu begründen. Gemäß ihrer Untersuchung beweisen positive Testergebnisse nicht hinreichend, dass mit SARS-CoV-2 Infizierte andere Personen mit dem Coronavirus anstecken können. Zusammen mit Wissenschaftler:innen der Universität Münster und dem MVZ Labor Münster hatten sie zuvor rund 190.000 Ergebnisse von mehr als 160.000 Menschen dahingehend ausgewertet.
