Summer Streets with New York Botanical Garden

Thursday, August 18th, 2011

Things on the BioBus were simply floral during a NYBG street fair on Saturday, August 13, 2011. The fair was held to celebrate Farmers’ Market Week, and it is safe to say that there was a large variety of produce offered by both NYBG stands and the actual farmers’ market. There, the BioBus’ staff (comprised of Dr. Ben, Nikki, Juliana, & Jordan) bought some beautiful bouquets hosting a variety of flowers…most of which were immediately brutalized by one Juliana (an intern at the BioBus) via scalpel. These lovely dissected samples were not wasted though! No, every and each sliver was carefully placed under the BioBus’s stereo microscopes under high magnification. Many children learned about the reproductive aspects of those flowers: where the specific organs are located and how a flower is pollinated. Some even got a short description of a plant’s vascular tissue, by yours truly. All the while, each person was given a sheet of paper containing visual aids with labeled arrows to aid them in their search for the plant reproductive organs.

“He’s so amazed; he’s trying to look at every part of the flower,” exclaimed an enthused mother, whose son was preoccupied with a bright red specimen.

These sheets even had spaces laid out for everyone, mainly the children, to draw what he had seen! Everything that was viewed, from the original flowers to their magnified samples were messily recorded and pasted onto the bus itself, and there they stayed until the event’s end.

The festival was a great success; as a man on a loud speaker announced, people were caught groaning that they had to leave. That made me snort. It was a long couple of hours that were extremely enjoyable.

The BioBus’ Third Annual Visit to the Gathering of the Vibes

Wednesday, July 27th, 2011

From July 21st  to July 24th, 2011, the BioBus was busy attending the Gathering of the Vibes, a four day music festival in Bridgeport, Connecticut. It was a huge hit and as word spread about its powerful microscopes depicting an almost alien world of creatures, people flocked to sneak a peek. A local radio station interviewed Sarah Weisberg about the BioBus, and numerous listeners who heard it on their way to the festival couldn’t wait to see for themselves.

Every morning at 11:00 AM, Dr. Ben and his anxious helpers would visit the water during high tide and collect samples. The samples would be observed throughout the day utilizing the professional microscopes. They were extremely diverse: krill, snails, lipids, barnacles, baby starfish, sand worms, crabs, and hermit crabs were just a few of the organisms collected from the Long Island Sound that fascinated the spectators. Once the festival-goers were taught to use a microscope they would visit the white pail teeming with life and choose what to discover next. A young man stood in awe in front of the screen projecting the magnified barnacles and exclaimed it appeared to be another world—one of the many reactions to seeing organisms that, without a microscope, appeared to be little more than tiny moving specks. Those fascinated by the BioBus would often come back later with companions and introduce them to an unbelievable new way to look at ordinary animals. People of all ages realized that there was so much more in our world than what can be perceived through the naked eye.

BioBus—Divide, Embryo, Divide!

Thursday, July 14th, 2011

Prof. Mark Allegro, at MBL in Woods Hole, decided to help the BioBus capture live cell division on film Wednesday, July 13, 2011!

The video can be viewed here:

This synchronized proliferation of cells is the beginning of life. In the video, what appears to be a round boundary starts out filled by two seemingly-large, but really microscopic, cells. This boundary, and its contained cells, is what make up an embryo, or the first sign of a living thing after an egg is fertilized. That ball is really just the beginnings of a baby…sea urchin. Well, that sea urchin must have some very proud parents, because the BioBus has decided to use it as an example depicting the early development of practically all organisms: “Look, that’s my developing urchin on TV!”

While the video made the division of these cells appear to only take a few seconds,  in reality the event was recorded over the span of an hour and was sped up for our enjoyment. If you pay close attention to the embryo, you will see that the cells making up the embryo keep getting smaller as they divide. They have to do this to divide as fast as they do. They cannot just stop to refill on cell juice (a.k.a. cytosol), or other parts just yet! So, they divide a few hundred more times until the cells are extremely numerous and tiny, then they reorganize themselves in specific shapes, and they grow in size by taking in nutrients.  The subsequent embryonic divisions and reorganization of cells actually precede the formation of something more universally recognizable: a fetus, or a baby.

BioBus—Vegetable Oil Filter

Wednesday, July 6th, 2011

It is true that the BioBus’ current engine runs on ecological fuel—fuel that harmless to the planet. It is also true that the bus can attain that fuel—vegetable oil—for free from any restaurant or fast food place. Don’t forget, though, that any oil that is donated to the BioBus is used, dirty oil! All of that dirty oil can’t get poured into the BioBus’ engine straightaway!

No, that oil contains copious amounts of food gunk, bacteria, water, and glycerin (a thick, colorless, and sweet-tasting liquid found in most beauty products) that would ruin any engine. Before using it, Dr. Ben has to separate the refuse from the vegetable oil.

Luckily, the BioBus owner has thought up an answer to this dilemma: a filter system. Said system, when I tried to research it, was a total mystery to me! In fact, Dr. Ben had to send me a diagram of the BioBus’ engine, only for me to stare at it blankly in confusion. Thusly, I asked Dr. Ben to explain to me just how the four-step filtration system works, and here’s how he put it:
“Step 1: When we suck grease out of any dumpster behind a restaurant, there is a strainer that filters large chunks (over 150 micrometers) of matter from the oil before it ever enters the bus.

Step 2: Between the dirty tank and the clean tank, there is a PRIMARY VEG FILTER that separates matter 30 micrometers or more—a marine-grade fuel filter.

Step 3: Between the clean tank and the valve assembly in the engine, the SECONDARY VEG FILTER separates water from the fuel, as well as anything 10 micrometers or larger—another marine-grade fuel filter

Step 4: There is a 10 micrometer water separating diesel fuel filter that is a normal part of the engine, which both the vegetable oil and the regular diesel fuel passes through—called the SECONDARY DIESEL FILTER.

Filters 1, 2, & 3 are ones that we put in, filter 4 is a regular part of the engine.”

His explanation, which was much easier to understand than the diagram was, gave me the impression that each filter is like different level of filtration. The first level is easiest to get through, because the stuff that gets stuck in it is the largest. Then, as the filters progress, more and more refuse is limited by the smaller filters. The vegetable oil at the end of the last filter is then guaranteed to be perfectly suitable for the engine!
