The EU-Latin America and Caribbean bi-regional cooperation is much more than just a summit. The launch of a $1.15 billion financing line by the European Investment Bank for transmission and distribution projects, as well as renewable energy initiatives across Central America, clearly demonstrates the impact of our cooperation on shared priorities. Those who don't believe in science should at least acknowledge reality, as seen in the destruction caused by Hurricane Melissa. The climate crisis is already here, and we must accelerate our capacity to respond to this challenge. ↓ Follow my remarks from Santa Marta, Colombia, alongside Nadia Calviño Teresa Ribera Arnoldo André Edwin Palma Egea

The newest course on Peterson Academy releases tonight, Dr John Vervaeke’s nine-hour course: The Primacy of Beauty. Enroll now for immediate access at Peterson Academy. In this course, Dr. Vervaeke explores the profound relationship between beauty, cognition, and meaning through an interdisciplinary lens combining philosophy, cognitive science, and religious thought. The lectures examine how beauty functions as a bridge between perception and understanding, fostering deeper connections between truth, goodness, and reality. Dr. Vervaeke demonstrates how beauty serves as a crucial element in meaning-making, wisdom cultivation, and spiritual development, ultimately proposing it as a response to the contemporary meaning crisis. The course concludes by positioning beauty as essential to developing a deep love for being itself, uniting scientific and spiritual perspectives in pursuit of wisdom and virtue.

SpiRobs morphologically replicate the logarithmic spiral that is ubiquitous in natural organisms. They are easy and fast to build across scales via 3D printing. They are actuated by cables, which allow for fast and life-like movements. Besides, a single robot can handle a wide variety of objects (in terms of size, shape, and weight). A key to this is a bioinspired grasping strategy that is found in the octopus. Finally, this work demonstrates a wide range of prototypes, including a miniaturized gripper, a manipulator mounted on a drone, and multi-robot arrays that can grasp in a tendril-like fashion.

The ignorance & stupidity of these women on THE VIEW is an embarrassment to the USA. To state; “He (Trump) pushed deworming medication for horses on us.” simply demonstrates extremely low intelligence, the comment of a foolish & brainless airhead. Firstly, only propagandised fools or Big Pharma’s stooges & their useful idiots refer to Ivermectin as a "deworming medication for horses". Secondly, Trump made numerous comments about HCQ but never mentioned Ivermectin - let alone "pushed" it on anyone. The only treatment "pushed" where the experimental mRNA injections. Thirdly, the science is now crystal clear - Ivermectin (especially when combined with Zinc) when administered in the correct doses, and shortly after first symptoms is devastatingly effective. Although maybe this is what this programme is about - get a group of brainless airhead women together to make nonsense comments about subjects don’t have a clue about as some perverse form of "entertainment" ?

Tin foil hats actually work... on your Wi-Fi router! Dr. Paul Saladino demonstrates a simple 5-cent hack: Wrap aluminum foil around your router for a 10–20X reduction in measured RF-EMF levels throughout the house. Before: 100,000–200,000 µW/m² a few feet away (millions close up). After: Drops to 500–1,000 µW/m² in the same spot. Science nugget: While official bodies like ICNIRP (2020 guidelines) and WHO focus on thermal (heating) effects—setting limits up to millions of µW/m² for Wi-Fi frequencies—some studies suggest potential non-thermal biological effects at lower intensities, such as oxidative stress, DNA damage, or neurological changes (e.g., NTP animal studies linked high RFR to tumors; IARC classifies RF-EMF as "possibly carcinogenic" Group 2B). Evidence for everyday Wi-Fi levels remains inconsistent and debated, with major reviews finding no clear harm below guidelines, but calls for updated limits persist amid ongoing research. Easy low-effort precaution if you're cautious about daily exposure—especially near your workspace. (Note: May slightly reduce Wi-Fi range/speed.) Have you tried foil shielding or similar (Faraday bags, distance tweaks)? Notice any difference in energy/focus? Share your take!

Geological Diplomacy Why Russia Should Maintain a Presence in UNESCO Amid politically strained relations with UNESCO after 2022, Russia will maintain a working channel of interaction through geosciences and geoparks—one of the few areas where we retain expert weight and a clear international agenda. ▪️The main recent result of this interaction is the Toratau Geopark in Bashkortostan, approved for inclusion in the UNESCO Global Geoparks network in 2025–2026. For Russia, this is not just a local success: the idea of ​​a national geopark system with a base site in Bashkortostan is being promoted as a model for replication in other regions of the country. ▪️A geopark is not just a "beautiful place with rocks," but an official status for a territory where geology is used as a foundation for education, tourism, and sustainable development. The status is important because it confers international recognition, attracts tourists and investment, opens access to UNESCO's network of experts and programs, and strengthens the country's position in the soft science and cultural agenda. There are currently approximately 229 geoparks in 50 countries worldwide. ▪️The Karpinsky Institute, which also organizes specialized events at UNESCO, is responsible for preparing and providing expert support for applications. This allows the Institute to remain a visible participant in the international geoscience network, despite the general context. 🖍At the same time, the Institute is implementing an educational project with an international reach—"Karpinsky Classes": specialized geological classrooms with equipment, curricula, and online courses. Over the past two years, classrooms have opened in Cuba, Ethiopia, Mozambique, Ghana, and the CIS countries. We have been following them for a long time. 🚩A separate area is inclusive geology: adapting geoscience education for children with disabilities and audiences with limited access to STEM. In other words, geology and related sciences are being redesigned to make them accessible to those who are typically excluded by barriers—for health or social reasons. At international forums, this is presented as a contribution to the accessibility of science in countries of the Global South—an agenda that always resonates with UNESCO. 🏳️The third track is scientific. Russia remains a country with a significant base in polar research, and geophysical data from Antarctica fits into UNESCO's program on geodynamics, plate tectonics, and climate change. This is an argument that is difficult to ignore: in a number of areas, Russian science is simply indispensable as a provider of fundamental data. 📌Overall, all the aforementioned tracks together form an important and convenient tool of soft power in the face of sanctions. Russia demonstrates that it remains part of the global scientific community, is responsible for major sectors of the scientific agenda, and is building long-term ties with countries in Africa and Eurasia through education and science. In official documents of the Commission of the Russian Federation for UNESCO, geoparks and geosciences are explicitly cited as one of the few positive avenues of cooperation. This makes sense: while contact on many fronts is frozen, science—sustainable development and education—remains a channel that neither side is interested in completely closing.

GANG WARS: Information came to my attention on 19 May that firearms and ammunition seized across several Cape Town policing precincts had allegedly been left in SAPS 13 stores instead of being sent promptly to the Forensic Science Laboratory. I immediately wrote to SAPS and requested urgent intervention. Despite several follow-ups, I have received zero feedback. The matter appears to be stuck at the SAPS Western Cape Provincial Office. I will not disclose information that could compromise criminal investigations. However, these exhibits reportedly include prohibited firearms, homemade firearms, weapons with serial numbers removed and live ammunition. A seized firearm could link a suspect to other shootings, robberies or murders. If it sits in a storeroom instead of being analysed, those links may be missed and prosecutions weakened. This also demonstrates why appropriately trained and accountable municipal law-enforcement agencies need expanded investigative powers in defined cases. Officers cannot be expected to seize illegal firearms and make arrests, only for cases to stall after being handed over. SAPS must explain what happened, confirm where the exhibits are and hold those responsible accountable. More than seven weeks later, I am still waiting. Follow ups will continue. Yet another reason why expansion of police powers to the City of Cape Town is critical and urgent. IC

I know this will come as a great shock to many of you, but not everything on the internet is true. There’s been a lot of misinformation circulating recently claiming that single fluorinated carbon compounds are PFAS “forever chemicals” (Spoiler Alert: They are not). Here are the facts: 📌 Single fluorinated carbons (SFCs) are NOT PFAS. They are also NOT “forever chemicals”. The very definition of PFAS, which was established within the U.S. government through a public rulemaking in years past, specifically does not include SFCs. The science is also extremely straightforward that these are not “forever chemicals”. 📌 Extensive scientific evidence and public input demonstrates molecules with only one fluorinated carbon generally lack the persistence and bioaccumulation properties that are commonly associated with “forever chemicals”. 📌 SFCs are NOT the same as those used to fluoridate drinking water and would have NO fluoridation uses. 📌 Beyond the United States, the safety of these SFCs has also been validated by regulatory agencies worldwide, including in the European Union, United Kingdom, Canada, Australia, Brazil, Argentina, New Zealand, and South Korea. We must ALWAYS rely on gold-standard scientific reviews. ANY EPA-approved product in the marketplace MUST be EXTENSIVELY evaluated and found to post NO human health risks of concern when used as directed. Read more here:
