      The prototype cells still need a little refinement. At present, they can generate current for up to 21 days; then they give up. So alternatives that last longer are needed.

    Two cases of rapid lethal intoxication with the herbicide glyphosate-trimesium (Touchdown) are presented. A 6-year-old boy who accidentally ingested a mouthful of glyphosate-trimesium died within minutes. The same happened to a 34-year-old woman who intentionally ingested approximately 150 ml of glyphosate-trimesium. The post-mortem examination revealed gastric content and oedema of the mucus membranes of the airways, erosion of the mucus membranes of the gastrointestinal tract, pulmonary oedema, cerebral oedema, and dilated right atrium and ventricle of the heart. The speed of which death occurs is much more rapid than lethal intoxications with the herbicide glyphosate (isoprophylamine), also known as 'Roundup'. It is suggested that the lethal mechanism between the two herbicides may be different. The component, trimethylsulfonium, of the glyphosate-trimesium may facilitate the absorption after oral ingestion. This difference can be crucial in the treatment of human intoxication. We propose that containers with glyphosate-trimesium must be labelled because of the apparent effect of lethal intoxication.

  88. Errors of omission by AllenChristopher · · Score: 1
    It's very frustrating that the slashdot crowd won't let you make *just one point*. You also have to address everything that might be similar to what you said, but isn't.

    I'm not attacking solar cells as they stand. I'm defending the usefulness of research into these new cells.

    Solar cells are very toxic to produceon a per-weight basis. This toxicity is manageable and less dangerous than NiCad. It pays for itself in lower conventional pollution and similar devices are being made heedless of the toxicity. Sure.

    I'd question the "locked away for 20-30 years" bit, in this context. If you were to put solar cells in more consumer electronics as the article suggests, you'd have the same issue with throwing them away to be melted down.

    Nonetheless, solar cells are manageable. The toxicity of nuclear power can also be well managed to provide some of the cleanest energy around. That doesn't mean solar cells, wind-power, and hydro aren't worthwhile to avoid dealing with the political hot potato that is nuclear waste.

    Like it or not, solar cell toxicity is an issue in the real world. It may be silly to worry about it, but the way solar cells chart is causing problems for them. Therefore, a less-toxic solar cell is a useful thing to develop, competitive in value with directly addressing homelessness. *This* is the point I was addressing, and what I said in defence of it is not a serious distortion of the facts.

    If you'd prefer to protest conventional CPU chips to make the whole thing fair, go for it. I'm going to A) not protest CPUs, considering the overall worth more than the cost, B) not protest current solar cells, and C) trumpet the arrival of cleaner methods of doing pretty much anything. Agreed?

    right! science shouldn't be expected to solve these very difficult socioeconomic problems

    They're not difficult. Not in rich western countries, anyway. There's just not the political will to do what it takes in many countries. Several other countries have had homelessness effectively eradicated for longer or shorter periods in the past, though the tendency recently ahs been to not give a fuck.

    Cancer, cleaner energy etc, those are hard problems that need science to solve. Many problems have already been solved by science, many have a science based solution that isn't being applied, and many have trivial common-sense solutions that aren't being applied. If the people in charge (and their voters) say "no thanks, I think I'll have the tax cut in stead", there's not a lot science can do about that.

    Bullshit. Mandatory Minimum sentences for even possession is what overflows prisons these days. Open up the other eye and examine the problem from both angles, don't try and spoon-feed me this rhetorical "Drugs are illegal because they are bad, therefore, Drugs are bad because they are illegal, mmmmkay??" line...

    As for the economy, think of what the economy is related to this particular vicious cycle. Currently the government is making far more revenue in kickbacks due to asset-seizure because of the black market economy, sending it into slush-funds and wasting it on pork and black-ops. Locking up people who would otherwise still be working, and going through treatment and removing that tax money from the coffers seems pretty dumb to me...it has seemed dumb for over 70 years.

  91. Actually, Hemp IS the greatest thing in the world. by syukton · · Score: 1

    Actually, the seed oils in drug type cannabis contain more compounds which can be extracted and turned into Biodiesel fuel. The traditional "hemp" seeds of the lesser-potency non-drug types of cannabis have about 30% fewer oils under identical growing conditions because they just have smaller seeds.

    Also, hemp IS the greatest thing for the world. It is one plant from which you can get the ingredients for:
    - Paper
    - Oils (both lubricating and fuel such as Biodiesel)
    - Textiles and clothing (Up to four times as soft as cotten when properly processed)
    - Rope (One of the big uses of hemp in WW2. Read about how domestic farmers were able to grow hemp during WW2 under the "hemp for victory" label, in order to supply the US government with the fiber it needed for uniforms and ropes and tents because the main hemp supply from the phillipenes was cut off)
    - Omega-3 fatty acids are contained within the seeds, and the derived seed oil is extremely good for you. (From the American Heart Association's website: "Omega-3 fatty acids benefit the heart of healthy people, and those at high risk of or who have cardiovascular disease.")

    And let us not forget the boon of farmland aeration and hillside retention. Cannabis plants can grow their roots up to six feet outwards laterally and up to two feet in depth over the course of ONE SEASON. This is THE MOST root growth of any plant known to man and makes cannabis perfect for holding up the ground in temporary landslide zones and aerating cropland. As it is an annual plant it would not serve much purpose as more than a temporary solution to a given problem.

    And the coolest thing is that you can get it all from ONE PLANT! One plant that grows in every state of the country unattended (it's a WEED!) and could solve all of our domestic energy needs, our domestic textile and paper needs, our domestic lubrication needs, and so on. Using the fiber of the stalks for textiles and paper doesn't take away from the oil production you get from the seeds and vice-versa, so the potential diversity of product from the first crop is very great.

    There are more reasons to legalize cannabis cultivation and processing than simply getting high. It holds benefits for mankind that far surpass the selfish moment of being totally stoned off your ass.
