16,000 Dead Pigs In The Huangpu: Can You Still Drink Shanghai's Water? | Popular Science - 1 views

  •  
    The dead pigs are being thrown into the water, not dying from the water. After being dumped in, they are becoming toxic in the river and emitting poison into the water.  The city of Shanghai relies on the river for the all the drinkable water in the city.  City officials have no idea how toxic the river has become, since no studies were done prior to the findings.  More research showed that the pigs are being dumped into the river because of costs of discarding the dead animal. It is cheaper to dump it, even though it could be toxic to the whole city.  Makes you wonder - we eat dead animals. But, when dumped in drinking water, they become toxic.... Hmmm.....

When hungry, Gulf of Mexico algae go toxic - 0 views

  • Karenia brevis algae, which cause red tide blooms across the Gulf of Mexico, become two to seven times more toxic when levels of phosphorus, a major algal nutrient found in fertilizers and human waste, are low.
  • excess nutrients like phosphorus and nitrogen play key roles in fueling algal growth and harmful algal bloom development.

Clostridium perfringens vaccines - 1 views

  •  
    The vaccine routes would use non-toxic fragments of alpha toxin or a non-toxic forms of whole toxin as immunogens. The antibodies would protect the alpha-toxins from binding to the C-domain cell membrane allowing for leukocytes to clear the bacteria.

For Cleveland, Climate Change Could Mean Tons of Toxic Green Algae - John Metcalfe - Th... - 0 views

  • The researchers say the potentially looming Algaeworld might be avoided if those in the agricultural industry use "better management practices." Having the U.S. agree to a solid climate treaty probably wouldn't hurt, either.

Disappearing Seagrass Protects Against Pathogens, Even Climate Change, Scientists Find ... - 0 views

  • Seagrass meadows, among the most endangered ecosystems on Earth, play an outsize role in the health of the oceans.
  • The plants also fight disease, it turns out. A team of scientists reported on Thursday that seagrasses can purge pathogens from the ocean that threaten humans and coral reefs alike.
  • But the meadows are vanishing at a rate of a football field every 30 minutes.
  • ...7 more annotations...
  • In one survey, they collected seawater and put it in petri dishes to see if colonies of disease-causing bacteria known as Enterococcus grew from the samples.
  • In a second search, the scientists grabbed fragments of DNA floating in seawater.
  • Water from the seagrass meadows had only half the level of this DNA, compared with water collected at other sites.
  • Reefs next to seagrass meadows, they found, were half as diseased as those without meadows.
  • Seagrass meadows can release so much oxygen that the surrounding water fizzes like champagne. That oxygen might be able to kill pathogens, Dr. Lamb realized. The plants also host fungi, which are known to producing bacteria-killing compounds.
  • Their research points to two main culprits. Eroded dirt washes into the Chesapeake, making the water cloudy. Seagrass get so little sunlight that the resulting dimming can be deadly.
  • Seagrass is also being pummeled by climate change. Warmer summer temperatures in Chesapeake Bay cause the plants to lose much of their oxygen through their leaves. With less oxygen to pump into their roots, they are poisoned by toxic sediments.
