Day 3: Smoke Signals In The Press Room

When there are 8,085 presentations at a massive scientific meeting, as is the case here in Atlanta for the 231st ACS National Meeting, you have to feel for those public information and public relations officers who are vying for the attention of a few dozen journalists. In their different ways, these peddlers of stories are trying to make their constituents stand out amid what amounts to a cacophonous din at a vast cocktail party.

One release teases me with this opener: “Microscopic specks of lead are offering clues about the enormous cultural changes that swept across Northern Africa thousands of years ago.” Not a bad lead. It draws me in enough that I continue to read and learn that the particular University of Arizona researcher featured in the release used an isotope analysis technique to trace the origin of copper and other metals in goods that were traded long ago in Northern Africa. I genuinely am intrigued by how such a technique, which by itself would not be of much interest to most people on the street, enables a scientist to connect seemingly insignificant specks of metal to trade patterns and from that to something as consequential as the spread of Islam in Africa. Even so, there are 8,084 other presentations at the meeting, so I might not want to lock onto this one.

Another release, this one from a government laboratory, is a harder sell. It’s about nanotubes and, who knows, it actually might be pointing me toward an important nanotube story. But nanotube stories have become a dime-a-dozen, a penny-a-dozen. I would be far more interested in a story about research that somehow bursts the nanotube bubble than by yet another story that puts a bit more glow on nanotubes’ celebrityhood. One saving grace about this particular release is that it centers on cerium oxide nanotubes, not carbon nanotubes. Still, we’re talking nanotubes here, and my threshold for even considering a nanotube story has reached what might be an unfairly stringent level.

“U.S., Polish researchers develop technology for creation of antiwear polymer films,” reads another release. Hmm. Not exactly a grabber for me at first, but then I discern a potentially interesting angle on the story because the two protagonists met at a conference in Poland in 1981 and now, 25 years later, they remain scientifically connected. It is the potential story about lifelong human connection and collaboration that initially catches me more than the researchers’ development of “tribopolymerization,” but even that topic could wear on me if I give it a chance.

Too late. There are many other releases in the press room, each one amounting to a humble “psst,” trying to grab my interest, maybe enough to convince me to write a story. And then there are all those thousands of other talks not lucky enough to have their own associated press releases set down on a table in a press room. Maybe it’s among those that I’ll find the best tales to tell.—Ivan Amato, filed at 1:42 PM EST.

Day 3: Coca-Cola Chemistry

The crowd of undergraduate students at yesterday’s midmorning Food Chemistry symposium perked up as Lihong (Lilly) D’Angelo, a manager of functional ingredients at Coca-Cola, spoke about the science of soda.

Coca-Cola was first served more than 115 years ago at a small pharmacy soda fountain in Atlanta. That’s why the Coca-Cola museum (officially called World of Coca-Cola Atlanta) is located here. Now people in more than 200 countries around the world recognize the brand name—although the product itself might be banana-flavored, depending on what country you are in.

Because natural and artificial sweeteners are main ingredients in soda, chemists at Coca-Cola study them extensively and create new ones, such as the noncommercial CC-100. They have developed a model that can predict the sweetness of a new molecule before synthesizing it. D’Angelo reported that the predictions are usually accurate.

In addition, she explained the basics of flavor chemistry, noting, for example, how chirality can mean the difference between spearmint and caraway flavors. Preparation techniques can alter flavors, too. For example, distilled lime tastes “spicy” and cold-pressed lime is “clean,” D’Angelo added, as she presented corresponding spectral analysis. Acid catalysis during distillation accounts for the difference, she said.

Other scientists contribute to the final soda product. For example, food technologists help develop product formulations. Analytical chemists do quality assurance tests for a consistent product. Microbiologists make sure the soda is safe to drink. Polymer chemists collaborate with engineers to design materials for bottles that won’t break during transport to consumers.

D’Angelo holds a Ph.D. in chemistry and an M.B.A. Her previous projects at Coca-Cola include developing new sweeteners. Currently, she works on chemistry to keep flavors stable in some of the other food products that Coca-Cola produces, such as Fanta and orange juice. And in her free time, she judges school science fairs and coaches tennis for Special Olympics.—Rachel Petkewich, filed at 6:34 AM EST

Day 3: Kenny Chemist Tops Tchotchke Roundup

Some attendees at an ACS National Exhibition map out their booth visits ahead of time, while others breeze in between scientific sessions to see what’s new. Yesterday, I stepped into the hall in Atlanta with a strict purpose: to scope out the best freebies.

More than 300 exhibitors and technical personnel from chemical and biotech companies, laboratory equipment suppliers, scientific staffing companies, book and journal publishers, software developers, universities, and government agencies were on hand starting yesterday to show off their products and services in Halls B2 & B3 in the Georgia World Congress Center. Most all of them have stamped their logos on a little something you can take home. What that is varies greatly.

I foraged through 20 aisles of booth real estate stocked with towering displays, dramatic glassware setups, gloveboxes, instruments, conference tables, and oodles of friendly representatives asking how I was. But I refrained from picking up the standard stuff—candies, pens, pencils, business cards, brochures, and fact sheets. Other attendees, however, happily scooped it into their bags and entered ubiquitous raffles for iPods. What else is there besides pens and iPods? Plenty! Here are the highlights of my collection.

Cool stuff: Squishy foam squeeze balls, a genuine beaker mug, stylin’ safety glasses, a reversible slotted and Philips screwdriver that I was warned not to carry on the plane home. I resisted most periodic tables, but grabbed a couple of attractive ones.

Highly notable items: The ACS Insurance booth offered both a 2-in-1 puzzle-and-ruler and a tote bag that folds down to a rather compact rectangle that snaps shut. I also really liked Sigma-Aldrich’s Precision Seal Septa Sizer, which was essentially a red rubber coaster with raised circles representing actual joint sizes.

The pièce de résistance: I acquired my very own Kenny Chemist at the Teledyne ISCO booth. This bobblehead doll poses with a representation of the company’s disposable column chromatography line. And, as the sales rep pointed out to me, Kenny really bops his head when he sits on a chromatographic system.
