  5. theguardian.com/world/2026/aug. I say again, #Russia has ALREADY used #chemical & #radiological #weapons on #British #soil, against people living here, & a British #citizen, in one case. It has also used #cyberwarfare against us. #Putin thinks he can strike at us with #impunity - WE must demonstrate to him that he is wrong.

  7. Lobotomy – Trust The Science

    1930s: the lobotomy enters practice and takes a Nobel Prize with it.  Trust the Science. Portuguese neurologist António Egas Moniz developed the prefrontal leucotomy (lobotomy) in 1935. He won the 1949 Nobel Prize in Physiology or Medicine for its therapeutic value. Not so much one can say about that!! Let’s look at the amazing scientific research that was done on this….  Moniz heard about chimpanzees acting calmer after brain surgery. He drilled holes in human skulls and cut […]

  12. For #Indigenous communities in ‘#Alberta,’ the #OilIndustry has left an ugly stain

    Facing #OilSpills, evacuations and #illness — nations downstream of the #OilSands grieve their way of life, as the #corporations polluting their water get richer

    By Brandi Morin, December 7, 2023

    Excerpt: "The rush of the wind and sprays of water add to the thrill as Jason Castor guides his riverboat through a stretch of #LakeAthabasca near #FortChipewyan, in #Treaty8 territories. If he slows down, his boat could get stuck in the mud or even flip over because the water levels in this spot are remarkably low. He steers around buoys, dodges logs and other debris while accelerating to the mouth of the channel, which he knows should be deep enough to navigate at an average speed.

    "While trawling his boat further down the river, Castor points to odd-looking clusters resembling dirty foam floating by.

    " 'There’s just a slurry of a foam that looks like #oil or some kind of #chemical in there,' says Castor, a 42-year-old father, construction business owner and member of the #AthabascaChipewyan #FirstNation (#ACFN).

    "He’s been a traditional hunter, trapper and fisherman for nearly 20 years and has documented strange changes in the water, the land and animals.

    "Something’s going on in the river, he says.

    " 'They say that it’s natural, well, I know that that’s not natural because I’ve been on the river my whole life,' he explains as he points to brown and #WhiteFoam, #OilSheens and other discoloured formations floating on the river.

    "Nowadays, it’s risky to navigate these waterways because of industrial intakes like the #WACBennettDam to the west in B.C.; the #AlbertaOilSands just up the river and impacts from #ClimateChange.

    "The #PeaceAthabascaDelta is the second-largest #freshwater delta in the world.

    "The #AthabascaRiver, and the larger delta, also sit atop the world’s largest known reservoir of #CrudeBitumen.

    "The industry that has sprung up around it drives Alberta’s and Canada’s economy, employing about 138,000 people. In 2021, crude bitumen production totaled approximately 3.3 million barrels per day. The oil sands energy sector including oil sands, conventional #OilAndGas, mining and quarrying is valued at about $18 billion.

    "But while Canada prospers off the oil sands industry, #Indigenous communities downstream are dealing with its #toxic impacts.

    "Not only are the water levels fluctuating, but the health of the water flowing through the Athabasca River is jeopardized."

  14. Here is a problem that has been quietly gnawing at astronomers for decades.

    The standard approach to detecting #life on other worlds involves scanning #exoplanet #atmospheres for #oxygen, #methane, and #ozone, whose presence is difficult to explain without #biology.

    It's a clever idea, but it carries a hidden flaw. That entire shopping list was written by studying Earth. It is, inevitably, a search for life like us.

    The list of ways that #chemistry alone can accidentally mimic these #biosignature gases is growing faster than the list of new ways to detect life.

    Each new false positive scenario demands even more information about the #planet to rule it out, and there is a genuine question about whether that information can ever be gathered exhaustively.

    But there is a solution.

    #Assembly theory doesn't ask what #molecules are present in an #atmosphere. Instead, it asks how hard they were to make.

    Every molecule can be assigned an assembly index, a minimum number of construction steps required to build it from basic #chemical building blocks.

    Simple molecules are easy to assemble by chance, but truly complex ones, requiring many sequential steps, don't arise without something doing a great deal of deliberate selection.

    That something would then be life itself.

  15. #GeneralGalactic’s water 💧 propulsion system could provide 5-10 times the Delta-V of traditional systems. For #chemical propulsion, it will use electrolysis to split water, then burn the hydrogen with oxygen as the oxidizer. For #electrical propulsion, it will split water and then apply sufficient electrical energy 🔋 to convert the oxygen into plasma. It will then use a #magnetic field to guide the plasma out of a thruster interestingengineering.com/spa

  16. #Ukrainian #drones attack #Russian #chemical plant in #Stavropol Krai

    The chemical plant, which supplies nitric acid used in the production of high #explosives such as #octogen and #hexogen, key components in #artillery #shells, has come under drone attack for the second time in two months

    Following a previous strike in June, the facility had already suspended operations, according to Astra.

  19. #Scientists created #microscopic reactors capable of driving light-powered #chemical processes by designing metal complex surfactants (MeCSs) that self-assemble into #nanoscale spheres called micelles. This innovation could drastically reduce #pollution in industries including #pharmaceuticals and materials science, where harmful organic solvents are often necessary.

  20. Just like with #PFAS-laden #FirefightingFoam, less #Toxic alternatives are out there, but expense is often cited as a roadblock. TBH, things that benefit the environment and society shouldn't cost more than the toxic originals -- and toxic chemicals should be replaced! Period! Make #BigChemical pay! (Since they probably knew about the hazards but hid them from the public. As usual with Big anything these days...!)

    A #PinkPowder is being used to fight #CaliforniaFires. It's getting everywhere

    by Nadine Yousif, January 13, 2025

    "Its use has been controversial in the past over its potential effects on the #environment.

    "A lawsuit filed in 2022 by the #ForestServiceEmployees for #EnvironmentalEthics, an organisation made up of current and former employees of the #USForestService, accused the federal agency of violating the country's clean water laws by dumping #chemical #FireRetardant from planes onto forests.

    "It argued that the chemical kills fish and is not effective.

    "The following year, a US District judge agreed with the employees, but in her ruling allowed the Forest Service to continue using the retardant as it seeks a permit to do so from the US Environmental Protection Agency (EPA).

    "The case drew the attention of communities devastated by #wildfires in the past, including the town of #ParadiseCalifornia, which was destroyed by fire in 2018.

    "Its then-mayor, Greg Bolin, hailed the judge's ruling, saying it ensures communities 'have a fighting chance' in the face of fires.

    "The Forest Service told NPR that this year, it phased out the use of one type of #PhosChek formula - #PhosChekLC95 - in favour of another - #MVPFx - saying that the latter is less toxic to #wildlife.

    "The Forest Service also has a mandatory ban in place on dropping fire retardant in sensitive environmental areas, like waterways and habitats of endangered species. There are exceptions to the ban, however, in cases 'when human life or public safety are threatened.'"

  21. Tribes addressing the ‘#forever #chemical’ problem

    Two years after the Environmental Protection Agency found high levels of #Perfluoroalkyl and #Polyfluoroalkyl Substances

    #PFAS #contamination in the drinking water at the K-12 tribal school on the Leech Lake Reservation,
    💥students and staff are still forced to consume only water brought in from outside the building.

    Leech Lake is one place tribes are having to respond to the presence of PFAS -- a class of man-made chemicals used in fire suppressing foam, water repellents on textiles, and older nonstick cookware.

    ⚠️High PFAS exposure is connected to some health problems including cancer and thyroid disease.

    🔥Nearly 100% of Americans have PFAS in their body. Information specific to #Native #Americans is limited.

    Join Native America Calling to talk with some tribes that are trying to address PFAS in their water and explore what can be done.
