Smart Meter: Einfallstore fĂŒr Cyberangriffe im Stromnetz

(April 6, 2026)

Die Studie unterstreicht, dass der Schutz kritischer Netzknoten oberste PrioritÀt haben muss. Neben der neuen Detektionsmethode empfehlen die Autoren:

– Kompromittierte Daten gezielt zu entfernen oder zu korrigieren

– StĂ€rkere Cybersicherheitsstandards bei der Entwicklung und dem Betrieb von Smart Metern

– Eine Kombination aus technischen und organisatorischen Maßnahmen, um die gesamte Advanced Metering Infrastructure (AMI) abzusichern

Die wichtigste Gegenmaßnahme ist allerdings sich kein Smart Meter aufschwatzen oder aufnötigen zu lassen. Die klassischen Ferraris-ZĂ€hler sind gegen jegliche Manipulation aus der Ferne gefeit, mangels Verbindung ins Internet. Und sie senden auch keine Hochfrequenz-Strahlung aus.

Trump Threatens ‘Leakers’ With Jail Time Over Reports About Munitions Shortages

(August 6, 2026)

Media reports have also said that the US has used up nearly all of its ATACMS missiles and Precision-Strike Missiles, which were both used extensively in strikes on Iran.

Trump also responded to a report from The Washington Post that said he lashed out at US Secretary of War Pete Hegseth over the munitions shortages, which one source told the outlet was part of the reason why Trump held off on his threats to dramatically escalate the war.

Sources told the Post that on the sidelines of a recent cabinet meeting at Camp David, Trump vented his frustration at Hegseth over the munitions shortages. The report said that Hegseth then blamed his deputy, Stephen Feinberg, for both the shortages and for failing to ensure Trump was informed about the issue.

Renewed Iran War Would Test Diminished Interceptor Inventories

(July 27, 2026)

Note: Estimated inventories today account for additional interceptor use and new deliveries since the April 8 ceasefire. THAAD deliveries during the ceasefire outpaced estimated use over the same period, resulting in higher inventories today than in April. Patriot calculations include the latest MSE variant and PAC-3s. Several hundred PAC-2s, not represented in the chart, are estimated to remain in the U.S. inventory.

Part of Earth’s core has switched directions. And nobody really knows why

(June 11, 2026)

The observation provides new insights into the behaviour of the liquid outer core, which plays a key role in generating Earth’s magnetic field. Without this magnetic shield, the planet would be dangerously exposed to solar radiation.

Researchers at the University of Edinburgh checked ground observations and satellite data between 1997 and 2025. They report in The Journal of Studies of Earth’s Deep Interior, that in 2010, a broad region of iron-rich fluid beneath the equatorial Pacific switched from moving weakly westwards to strongly eastwards.

NASA Shows Einstein Was Right: Our Sun Is Losing Mass – and Its Grip on Our Solar System

(January 19, 2018)

As our sun gets older, it‘s losing mass, and so its gravitational pull becomes weaker. As a result, the orbits of all the planets in our solar system are expanding, not unlike „the waistband of a couch potato in midlife,“ according to a new NASA press statement.

A team of researchers from the Massachusetts Institute of Technology, the University of Maryland and the NASA Goddard Space Flight Center has shown that the aging sun is behaving according to Albert Einstein‘s theory of general relativity.

Earth’s Rotation Is Slowing Faster Than In 3.6 Million Years

(June 7, 2026)

Earth’s rotation is gradually slowing as climate change melts glaciers and polar ice sheets, redistributing water across the planet and subtly lengthening the day. According to new research from the University of Vienna and ETH ZĂŒrich, the current increase in day length — 1.33 milliseconds per century — is unprecedented over at least the past 3.6 million years. It’s a new measure of how profoundly human-driven warming is affecting the Earth system, even as only 48% of Americans believe climate change is the result of human activity.

(…)

Researchers reconstructed changes in day length over the past 3.6 million years using fossil remains of benthic foraminifera — single-celled marine microorganisms on the seafloor — and advanced machine-learning techniques.

Securing the green grid: A data anomaly detection method for mitigating cyberattacks on smart meter measurements

(September 2024)

Smart meters, being a vital component in the advanced metering infrastructure (AMI), provide an opportunity to remotely monitor and control power usage and act like a bridge between customers and utilities. The installation of millions of smart meters in the power grid is a step forward towards a green transition. However, it also constitutes a massive cybersecurity vulnerability. Cyberattacks on AMI can result in inaccurate billing, energy theft, service disruptions, privacy breaches, network vulnerabilities, and malware distribution.

Gaza: Studie zeigt beispiellose Verluste an Menschenleben und Lebenserwartung

Ein Team des Max-Planck-Instituts fĂŒr demografische Forschung (MPIDR) und des Centre for Demographic Studies (CED) hat die Auswirkungen des Konflikts in Gaza auf die Sterblichkeit untersucht. Sie schĂ€tzen, dass zwischen dem 7. Oktober 2023 und dem 31. Dezember 2024 78.318 (70.614 – 87.504) Menschen in Gaza getötet wurden. Infolgedessen sank die Lebenserwartung in Gaza im Jahr 2024 auf weniger als die HĂ€lfte des ohne Krieg zu erwartenden Niveaus. Eine Aktualisierung ihrer Analyse, die nach der Veröffentlichung der Studie erstellt wurde, ergab, dass die Zahl der gewaltsamen TodesfĂ€lle derzeit wahrscheinlich 100.000 ĂŒbersteigt.

Gaza: study reveals unprecedented losses of life and life expectancy

A research team from the Max Planck Institute for Demographic Research (MPIDR) and the Centre for Demographic Studies (CED) investigated the impact of the conflict in Gaza on mortality. They estimate that 78,318 (70,614-87,504) people were killed in Gaza between October 7, 2023 and December 31, 2024. As a result, life expectancy in Gaza in 2024 fell to nearly half the level expected without the war. An update of their analysis, produced after the publication of the study, revealed that the current violent death toll likely exceeds 100,000.

Traumatic injury mortality in the Gaza Strip from Oct 7, 2023, to June 30, 2024: a capture–recapture analysis

Findings We estimated 64 260 deaths (95% CI 55 298–78 525) due to traumatic injury during the study period, suggesting the Palestinian MoH under-reported mortality by 41%. The annualised crude death rate was 39·3 per 1000 people (95% CI 35·7–49·4), representing a rate ratio of 14·0 (95% CI 12·8–17·6) compared with all-cause mortality in 2022, even when ignoring non-injury excess mortality. Women, children (aged <18 years), and older people (aged ≄65 years) accounted for 16 699 (59·1%) of the 28 257 deaths for which age and sex data were available. Interpretation Our findings show an exceptionally high mortality rate in the Gaza Strip during the period studied. These results underscore the urgent need for interventions to prevent further loss of life and illuminate important patterns in the conduct of the war.

Lancet Study: Gaza Health Ministry Undercounted Death Toll By 41%

Explaining the methodology, the study said it used “capture-recapture methods to estimate total deaths from traumatic injury in the Gaza Strip from Oct 7, 2023, to June 30, 2024. By combining three data lists—official hospital lists, an MoH survey, and social media obituaries—we provide an estimate of mortality that accounts for under-reporting.”

The study only accounts for deaths caused by violence and not indirect deaths caused by the Israeli siege and the destruction of medical and other civilian infrastructure.

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 ÎŒT) 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.

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.
