MicrobeWorld visits the Marian Koshland Science Museum for “Microbe Lab,” a free day of activities for the general public.
In this episode we interview Erika Shugart, deputy director of the Koshland Museum, about “Microbe Lab” and the Crack Koshie’s Curious Case: A Disease Detective Mission activity. Next, we talk with Nagla Fetouh, Education Program Manager for the Koshland Museum, who led a disease exchange activity that teaches people about ways to control the spread of infectious disease by participating in a simulation that shows just how fast illness can spread. Finally, Eric Flem, Communications Manager for Nikon Instruments, Inc., led us through a demonstration of Nikon’s Coolscope. A state of the art microscope used by clinicians and educators that has the ability to broadcast images live on the internet.

The web was abuzz Thursday with speculation NASA would announce it had discovered alien life on Earth. But when the press conference came around -- turns out the answer is... sort of.
Scientists discovered a type of microbe that can replace the phosphorous in its DNA with arsenic -- and survive, something no known organism has ever done before. The bacterium was found at the bottom of Mono Lake in eastern California, which has one of the highest naturally-occurring concentrations of arsenic in the world. (Video: NASA)
Prior to the discovery, biologists believed life was composed exclusively of six elements: phosphorous, carbon, oxygen, hydrogen, nitrogen and sulfur. A writer for The New York Times explains how arsenic fits -- or doesn’t fit -- for those of us who weren’t paying that close of attention in chemistry class.
“Arsenic sits right beneath phosphorus in the periodic table of the elements. … Indeed, that chemical closeness is what makes it toxic ... allowing it to slip easily into a cell’s machinery where it then gums things up, like bad oil in a car engine.”
But why does the discovery matter? On CNN, Bill Nye explains.
NYE: “See, you and I, everything you’ve ever met, except these microbes, relies on the same type of DNA, which has some phosphates. (FLASH) This idea that it’s possible to substitute things changes the way we look at living things and changes the way we think about what’s possible.”
VELSHI: “It’s like, what you thought of the possible world has now just been expanded.”
But while many applaud the results of the study as a complete game-changer, some are still doubtful. A writer for Popular Science writes...
“To be clear, the scientists made this happen in a lab. They removed phosphorus from the bacteria’s environment and enriched it with arsenic. It was a complex game of chemistry that yielded strange results.”
An anchor for Los Angeles’ KABC felt let down after the flurry of speculation that NASA had actually found life from another planet.
“Doesn’t that seem a little anti-climactic? I mean they made the big announcement this morning, ‘Oh, here we are, it’s gonna be out there, we’re going to find life.’ And then it’s here. So the aliens are in us, not among us.
But The Washington Post’s Melissa Bell says that’s the wrong way of looking at the announcement -- This is HUGE.
“Before you get disappointed, realize that while not as sexy as a little green man, it is a big deal. No other life form exists off arsenic. ...This discovery shows [as a NASA biochemist put it] ‘life-as-we-know-it could be much more flexible than we generally assume or can imagine’...”
So what do you think? Does this discovery change life as we know it, or are you still disappointed NASA didn’t announce it had finally gotten hold of E.T.?

Scientists have discovered a diverse multitude of microbes colonizing and thriving on flecks of plastic that have polluted the oceans -- a vast new human-made flotilla of microbial communities that they have dubbed the "plastisphere."
Fine cheeses are like fine wines. Producing and aging them properly is
both an art and a science. From cave-aging to the use of raw milk,
watch Dr. Catherine Donnelley, Co-director of the Vermont Institute
for Artisan Cheeses, describe the microbial world of cheese.
Listeria and Salmonella are just a couple of the pathogens that pose a
risk to cheese consumers. In this episode of MicrobeWorld Video, Dr.
Donnelly explains how these risks are mitigated through strict
processing guidelines, why these safeguards make cheese one of the
safest commodities today, and how beneficial organisms contribute to
the cheese making process. In addition, Erica Sanford from Cowgirl
Creamery with the help of Carolyn Wentz from Everona Dairy walk us
through the steps of artisan cheese production.

Just like the Earth itself, our body is a living planet, a network of ecosystems where bacteria are the dominant life form. Throughout life’s journey we are invaded and become host to an army of microscopic bugs - both good and bad.

The odds of one over another microbe surviving in the primordial soup is what makes every existence precious and unique, because the odds are against a particular moment of conception over another... guess we lucked out!

These brave students are the face of the more than 50 college students who let *******SleepBetter**** cut into their old, nasty pillows and mattress pads -- for the good of science. The "Sleepbetter**** Investigates: Fungus Among Us" study, the largest of its kind, revealed a lot of not so fresh facts. Bottom line -- our bedding is a microbe reservoir where bacteria, yeast, molds and fungi not only survive but thrive! Check out each students reaction to the microbes living in their old pillows. Go to SleepBetter**** to look over the disgusting and alarming statistics.
