Inuit Researcher Finds High Arctic Micro-Plastic Pollution in Greenland

 Creating his own micro-plastics filter, a researcher kayaked around a Greenland glacier to look for the presence of micro-plastics. Toxic dust in the air and ocean currents to have redistributed micro-plastic pollution globally and made the Arctic a sink for microplastic pollution. The fossil fuel derivatives evidently harm cod eggs and human health.

Plainly President Trump should stop sanctions on Russia to expedite the end of the Ukraine war and develop a program to expedite a transition away from fossil fuels- even auto tires lose 15 to 30% of mass over use time as it converts to dust that can become airborne. TWPs (tire wear particles) are a major source of micro-plastic pollution. Every year another two or three billion are manufactured and released to float micro-plastics into the atmosphere and Earth. Ending the Ukraine war would enable closer work together among nations to war upon high Arctic micro-plastic pollution that is probably harmful to whales and various fish species instead of on other humans.

Hydrogen is a good direction for alternative fuels to take. New science is progrogressing on developing hydrogen from seawater at low cost with common materials. Alternatives to fossil fuels are taking many forms and the U.S. tends toward lagging behind in the race to China, Australia and other nations. Solar panels are reducing in price globally although the U.S.A. may have sanctions on importing them. Maybe the administration doesn't want the U.S.A. to develop as an independent off-grid society in order to concentrate wealth to fossil fuel energy corporations.

Gemini wrote this about the Australian hydrogen research;

Gemini- Australian researchers, notably from the University of Adelaide and RMIT University, have developed a groundbreaking method to produce green hydrogen directly from seawater without pre-treatment or desalination. Using specialized catalysts and a Lewis acid layer, this technique achieves near 100% efficiency, offering a sustainable, cost-effective alternative to traditional, water-intensive methods. 

Key Breakthrough Details

• No Desalination Needed: The process skips energy-intensive purification, directly splitting raw seawater into hydrogen and oxygen.
• Catalyst Innovation: Researchers, including those from the University of Adelaide, used a catalyst with a specialized layer (e.g., Lewis acid) to prevent chloride corrosion, allowing the system to run for over 100 hours.
• Efficiency: The technique demonstrated performance close to platinum-based catalysts that currently require highly purified water.
• Environmental Impact: This method provides a sustainable pathway for producing green hydrogen, utilizing the ocean as an "almost infinite resource" while avoiding chlorine byproduct issues. 

New Developments (2026)

Recent advances in 2026 from the University of Sydney have introduced a method using liquid gallium and sunlight, allowing for the direct extraction of green hydrogen from seawater without requiring external electricity, furthering the efficiency of the process. 

This innovation is considered a major step toward making the green hydrogen economy more viable, bypassing the need for freshwater, which is crucial for water-scarce regions."- end Gemini quote 

Humans apparently occupied a cave site in Greece named Theoptera from 130,000 BC. A structural weather wall was built there about 23,000 B.C. It is notable that politicians find it so difficult to advance from a dysfunctional polluting fossil fuels tool kit to a newer one technologically. It was perhaps difficult for Neanderthal and human political leaders at Theoptera to accept new technologies when they appeared as well.

Nano-machine Replacements for Plastic Bags- A Progress Report by Grok

There are myriad alternative ways to replace plastic bags or at least scale up the size of the plastic in order to avoid very small micron sizes that allow easy absorption into biological cells. One of the more interesting one is that of nano-machines. I had a conversation with Grok- prompting Alex as he is known alternatively;

Gary- Could semi-intelligent nano-machines form bags that serve like plastics yet when their purpose is served, collapse into a powder or maybe a cube for recycling as another bag?

Grok- Thought for 39s

"Yes, the concept of semi-intelligent nano-machines forming bag-like structures that function like plastics and then collapse into a powder or compact cube for recycling is theoretically feasible, drawing from emerging research in programmable nanomaterials, molecular robotics, and self-assembling systems. While we're not there yet for everyday consumer products like grocery bags, foundational technologies demonstrate assembly and disassembly on command at the nanoscale, with potential pathways to scale up for macroscopic applications.

Core Principles and Feasibility-At the heart of this idea are "smart" nanomaterials or molecular machines that can respond to external triggers (e.g., chemical signals, solvents, light, or temperature) to organize into functional structures and later break down controllably. These aren't fully autonomous "intelligent" nanobots like in science fiction, but rather engineered molecules or particles with programmed behaviors:

• Self-Assembly: Nano-machines could use weak intermolecular forces (like hydrogen bonding or DNA hybridization) to link together, forming a flexible, impermeable network similar to plastic polymers. For a bag, this might create a thin, durable sheet that holds shape under normal use.
• Disassembly on Command: Once the bag's purpose is served, a trigger could disrupt those bonds, causing the structure to collapse. This might result in a fine powder (dispersed nanoparticles) or, with more advanced control, a self-organized cube (via directed reassembly into a compact form). The components could then be recycled by reassembling them into new bags, minimizing waste.
• Semi-Intelligence: The "intelligence" comes from built-in molecular controllers or circuits that process signals autonomously, allowing the system to decide when to assemble/disassemble without constant external input.

This aligns with sustainable manufacturing goals, where materials are designed for infinite recyclability without energy-intensive melting or chemical breakdown.Supporting Research and ExamplesRecent advancements show this isn't just hypothetical:

• Swarm molecular robots, propelled by kinesin motors along microtubules, can self-assemble into bundled structures via DNA signals from a coexisting molecular controller. An "assemble" command aligns them into formations, while a "disassemble" signal disperses them automatically. This autonomous process, regulated by a DNA circuit, could inspire scalable systems for dynamic materials. phys.org Though currently microscopic, extending this to larger scales might involve hierarchical assembly (nano to micro to macro).
• A self-assembling electrolyte for EV batteries uses aramid amphiphile molecules that spontaneously form nanoribbons in water, which can be pressed into a solid structure. Immersion in organic solvents causes rapid disassembly—like dissolving cotton candy—separating components for easy recycling. news.mit.edu Researchers note this reversible process could adapt to packaging, such as bags that assemble for use and collapse into recyclable forms on a solvent trigger, avoiding traditional plastic pollution.
• Broader nanotech design principles advocate building disassembly directly into products, such as using reverse assemblers to break items into reusable elemental components or enabling biodegradation into harmless parts. azonano.com Proposals like a "Law of Disassembly" emphasize ensuring all nanotech items have at least one safe breakdown pathway, which could apply to macroscopic items by programming nano-units to revert to a powder or cube state for collection and reuse.

Other work, like self-folding origami robots or programmable 2D nanosheets, further supports the idea of materials that change form autonomously. herox.com +1Challenges and Prospects

• Scaling Up: Current demos are at nano/micro scales (e.g., for drug delivery or batteries), not macro like bags. Achieving uniform assembly over square meters would require trillions of nano-machines working in concert, plus ensuring mechanical strength comparable to plastics.
• Cost and Viability: Production of such nano-machines (e.g., via DNA synthesis or chemical engineering) is expensive now, but costs are dropping with biotech advances. Quantitative viability could emerge if raw materials are cheap and recycling loops are closed.
• Triggers and Safety: Disassembly might use benign triggers (e.g., water or mild solvents) to form powder, or magnetic/electric fields to compact into a cube. Ensuring they don't accidentally disassemble (e.g., in rain) or pose health risks (e.g., inhalable powder) is key.
• Timeline: Prototypes for niche applications (e.g., medical or military) might appear in 5–10 years, with consumer packaging following as regulations push for zero-waste materials.

In summary, while full implementation requires further R&D, the building blocks exist, and this could revolutionize plastics by making them truly circular and eco-friendly."
