Bird dieout. In 1991 in Monterey Bay, CA, dead and dying seabirds displayed unusual symptoms suggesting a neurological toxin. https://lnkd.in/efqksX7 View in LinkedIn

THE BIRDS. "On August 18, 1961, in Capitola and Santa Cruz, California there was an invasion of what people described as chaotic seabirds. These birds were believed to be under the influence of domoic acid, and it inspired a scene in Alfred Hitchcock’s feature film The Birds (1963)." Think glutamate receptor flooding by domoic acid toxin. https://lnkd.in/ea6_24c View in LinkedIn

HARMFUL ALGAL BLOOMS. "Many countries are faced with a bewildering array of toxic or harmful species and impacts, as well as disturbing trends of increasing bloom incidence, larger areas affected, more fisheries resources impacted, and higher economic losses." https://lnkd.in/eWsTQBZ View in LinkedIn

HARMFUL ALGAL BLOOMS. "Several decades ago relatively few countries appeared to be affected by HABs, but now most coastal countries are threatened, in many cases over large geographic areas and by more than one harmful or toxic species." https://lnkd.in/eWsTQBZ View in LinkedIn

HARMFUL ALGAL BLOOMS are "caused by microscopic algae that produce toxins that kill fish and make shellfish dangerous to eat. The toxins may also make the surrounding air difficult to breathe. As the name suggests, the bloom of algae often turns the water red." https://lnkd.in/eiixYfT View in LinkedIn

HARMFUL ALGAL BLOOMS. "While many people call these blooms 'red tides,' scientists prefer the term harmful algal bloom. One of the best known HABs in the nation occurs nearly every summer along Florida’s Gulf Coast." https://lnkd.in/eiixYfT View in LinkedIn

"TOXIC ALGAL BLOOMS are increasing because of pollution of coastal waters and worldwide shipping." https://lnkd.in/e8RtJht View in LinkedIn

SLEIGHT OF HAND. "We need sugars in our diet, but if we were to eat the mirror image of these sugars, molecules that contain the same atoms but only arranged in the left-handed form, then we would starve, as our bodies can only metabolize the right-handed form." This is the basis for some calorie-free artificial sweeteners. https://lnkd.in/eqzkdcz View in LinkedIn

DIATOMS are known to be copper sensitive ("copper stress"). Domoic acid also detoxifies ambient coastal copper by the same chelation mechanism that it accumulates scarce iron micronutrients. A second survival technique, and a second biological function for domoic acid. https://lnkd.in/ex75rxA View in LinkedIn

TOXICITY. "One highly important issue is whether D-amino acids present in foodstuffs are toxic. It may be established from the outset that the various D- and L- amino acids are equally toxic, as verified by their LD50 values. D-proline may be an exception to this, higher lethality in chickens having been ascertained for this enantiomer than for L-proline." https://lnkd.in/eNSAN8h View in LinkedIn
