Past and present nuclear activities (energy, research, weapon tests) have increased the urgency to understand the behavior of radioactive materials in the environment. Nuclear wastes containing actinides (e.g. plutonium, americium, curium, neptunium…) are particularly problematic as they remain radioactive and toxic for thousands of years.

Lawrence Livermore National Laboratory (LLNL) scientists and collaborators proposed a new mechanism by which nuclear waste could spread in the environment.

The new findings, that involve researchers at Penn State and Harvard Medical School, have implications for nuclear waste management and environmental chemistry. The research is published in the Journal of the American Chemical Society.

Circa 2018 Imagine waste turned into gold.

No other life form on our planet has infiltrated every environment as successfully as the minuscule single cells of bacteria. Amongst their many roles in life on Earth, it turns out some of these microbes are also experts at purifying precious metals.

An international team of researchers has figured out how one metal-gobbling bacterium, Cupriavidus metallidurans, manages to ingest toxic metallic compounds and still thrive, producing tiny gold nuggets as a side-effect.

Four times faster than existing chemical rockets

In the seven months NASA estimates it would take to fly humans to Mars, any number of catastrophic failures could occur. That’s why Díaz said in a 2010 interview with Popular Science that “chemical rockets are not going to get us to Mars. It’s just too long a trip.” A conventional rocket must use its entire fuel supply in a single controlled explosion during launch before propelling itself towards Mars. There is no abort procedure, the ship will not be able to change course, and if any failure occurred, mission control would have a 10-minute communications delay, meaning they could find themselves helplessly watching on as the crew slowly dies.

Mars is the solar system’s near-miss world. Earth may have gotten everything right when it came to sustaining life—atmosphere, water, proximity to the sun. Mercury, Venus and the outer planets, with their extreme temperatures and inhospitable chemistry, may have gotten everything wrong. Mars, on the other hand, came so close, yet fell short.

Thanks to data from rovers and other spacecraft, we know that the Red Planet once fairly sloshed with water—with dry deltas, riverbeds, and sea basins stamped into its surface. But 4 billion years ago, the Martian core cooled, shutting down the dynamo that sustained its magnetic field. That left the planet vulnerable to the solar wind, which clawed away the atmosphere, and allowed the Martian water to sputter into space. Before long—in geological terms—the planet was a desert.

At least that’s long been the thinking. But a new paper published Sept. 20 in the Proceedings of the National Academy of Sciences suggests otherwise. According to the new research, Mars was doomed from the start. Its small size—about half the diameter of Earth and less than one-ninth the mass—simply never produced the gravitational muscle to allow the planet to hold onto either its air or its water. With or without a magnetic field, Mars was destined to die.

Maybe try a 100 percent recycling rate for sewage and chemical extraction.

As if going to the bathroom in microgravity wasn’t complicated enough.

It sounds as though the four space tourists on SpaceX’s historic Inspiration4 flight last week had a bit of a smelly mishap. The Waste Management System experienced an “anomaly” — that’s code of “uh oh” in space jargon — with its suction fan causing the crew to struggle with doing their business while floating hundreds of miles above the surface.

Red blood cells are the most abundant cell type in blood, carrying oxygen throughout the human body. In blood circulation, they repetitively encounter various levels of oxygen tension. Hypoxia, a low oxygen tension condition, is a very common micro-environmental factor in physiological processes of blood circulation and various pathological processes such as cancer, chronic inflammation, heart attacks and stroke. In addition, an interplay between poor cellular deformability and impaired oxygen delivery is found in various pathological processes such as sickle cell disease. Sickle red blood cells simultaneously undergo drastic mechanical deformation during the sickling and unsickling process.

The interactions between hypoxia and cell biomechanics and the underlying biochemical mechanisms of the accelerated damage in diseased red blood cells are well understood, however, the exact biomechanical consequences of hypoxia contributing to red blood cell degradation (aging) remains elusive.

Researchers from Florida Atlantic University’s College of Engineering and Computer Science, in collaboration with the Massachusetts Institute of Technology (MIT), sought to identify the role of hypoxia on red blood cell aging via the biomechanical pathways. In particular, they examined hypoxia-induced impairment of red blood cell deformability at the single cell level, compared the differences between non-cyclic hypoxia and cyclic hypoxia, and documented any cumulative effect vs. hypoxia cycles, such as aspects that have not been studied quantitatively. Red blood cell deformability is an important biomarker of its functionality.

face_with_colon_three Basically we simply waste chemicals that are sometimes used in compost but actually have literally millions of tons of chemicals gone to waste rather reclaiming these very expensive chemicals. For instance some medicine costs thousands of dollars to make and will not recycle completely even current compost problems are not seeing the literally value of wasted medical refuse dissolved in waste water. Literally possibly trillion dollars or more down the drain from waste but this new reclaiming system will reap the benefits 😗 Even new innovative recycled toilet paper is a new concept but someday even vital chemicals will not be wasted with these new reclaiming systems.

With sometimes offbeat technology, innovators seek to extract certain chemicals from municipal waste by.
