    This could have huge implications in the microbiology field. If they could somehow find an antibiotic use out of this fungus it could help fight bacteria that is resistant to most drugs on the market today.

    This gives "the ubiquity of bacteria" a whole new meaning. It is very cool that life can exist at the extremes.

  • 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.

    This is great news not only for what we've overlooked, but future implications that deep-sea life has a lot to offer in antibiotics. Another important factor is that we know more about the surface of the moon then our own oceans, so gives us the opportunity and a reason for categorizing deep-sea life.
