10 Keys to an Engaging Scientific Presentation

What makes an engaging scientific presentation? Georgia Tech Professor Will Ratcliff uses a method based on the style of nature documentary presenter David Attenborough. Ratcliff’s approach looks to capture an audience’s natural curiosity by using engaging visuals and simple storytelling techniques.

Here are his 10 keys to an engaging scientific presentation:

1) Be an Entertainer First: Before your science can wow your audience, they have to understand it. Before they can understand it, you must engage them with what you’re saying. Look at your presentation from your audience’s perspective and think about how they’ll relate to your material. Focus on presenting your science in a way that engages and entertains as it explains.

2) Be a Storyteller, Not a Lecturer: Don’t assume that your audience knows your field. Tell the story of your science: identify the big picture backdrop, your specific research questions, how you answer those questions, and how it affects the way we now think about the big picture.

3) Prioritize Clarity : If the audience doesn’t understand every word you use, they’ll stop paying attention, and you may never win them back. Your goal is to never lose their attention in the first place, so make an effort to be clear and have a simple narrative arc to your talk.

4) Mind Your Transitions: The easiest place to lose your audience’s focus is when you move from one slide to another. Practice the transitions in your talk to make sure the link between the ideas of one slide and the next remains clear.

5) Keep Complete Sentences Out of Your Slides: Keep the text in your slides to a minimum. Instead, use compelling visual to hold your audience’s attention while you speak.

6) Animations Are Your Friend: You can use animations to reveal new details on your slide as they become relevant to what you are saying. That way you get to control what your audience is seeing, minimizing distraction and putting laser pointers out of a job. Note: never use silly and unnecessary animations, like spinning or scrolling text, this will just annoy your audience.

7) Get Excited: If you’re not excited and energetic about your work, your audience won’t be either.

8) Look at the Audience: Don’t stare at the floor, the ceiling, or your slides while you’re presenting. Look directly at your audience, or if you’re nervous, toward the back of the lecture hall. This will help you connect with your audience.

9) Be Wary of Jokes: Scientific talks are serious by nature and you have more to lose than to gain. If a joke is poorly timed or if you misjudge an audience, you risk alienating them. Play it safe and find other ways to be entertaining unless you know your audience well.

10) Leave the Laser Pointer at Home: Laser pointers are distracting. If you feel you need one to guide your audience through a slide, that’s a sign your slide is too cluttered.

How A ‘Candy Cane’ Polymer Weave Could Power the Future of Functional Fabrics and Devices

Batteries, specifically lithium-ion batteries, dominate the energy storage landscape. However, the chemical reactions underlying the charging and discharging process in batteries are slow, limiting how much power they can deliver. Plus, batteries tend to degrade over time, requiring replacement. An alternate energy storage device, the supercapacitor, charges rapidly and generates serious power, which could potentially allow electric cars to accelerate more quickly, among other applications. Plus, supercapacitors store energy electrostatically, not chemically, which makes them more stable and long-lasting than many batteries. But today’s commercially available supercapacitors require binders and have a low energy density, limiting their application in emerging go-anywhere electronics.

Tiesheng Wang, a graduate student in the lab of Stoyan Smoukov, Ph.D., at the University of Cambridge (U.K.) suspected that a flexible conducting polymer-based material from another project they were working on could be a better alternative. Conducting polymers, such as poly(3,4-ethylenedioxythiophene) (PEDOT), are candidate supercapacitors that have advantages over traditional carbon-based supercapacitors as charge storage materials. They are pseudocapacitive, meaning they allow reversible electrochemical reactions, and they also are chemically stable and inexpensive. However, ions can only penetrate the polymers a couple of nanometers deep, leaving much of the material as dead weight. Scientists working to improve ion mobility had previously developed nanostructures that deposit thin layers of conducting polymers on top of support materials, which improves supercapacitor performance by making more of the polymer accessible to the ions. The drawback, according to Wang, is that these nanostructures can be fragile, difficult to make reproducibly when scaled-up and poor in electrochemical stability, limiting their applicability.

Watch Tiesheng Wang Explain His Research at the 255th ACS National Meeting & Exposition


Smoukov and Wang developed a more robust material by weaving together a conducting polymer with an ion-storage polymer. The two polymers were stitched together to form a candy cane-like geometry, with one polymer playing the role of the white stripe and the other, red. While PEDOT conducts electricity, the other polymer, poly(ethylene oxide) (PEO), can store ions. The interwoven geometry is instrumental to the energy storage benefits, Wang says, because it allows the ions to access more of the material overall, approaching the “theoretical limit.”

When tested, the candy cane supercapacitor demonstrated improvements over PEDOT alone with regard to flexibility and cycling stability. It also had nearly double the specific capacitance compared to conventional PEDOT-based supercapacitors.

Ancient Reaction Inspires Method for Making Porous Catalysts

A recipe for better electrocatalysts takes inspiration from an ancient reaction used in fireworks, known as the pharaoh’s snakes. With heat and the foaming power of baking soda, a simple mix of ingredients can be turned into a high surface area, nanostructured catalyst for oxygen reduction in fuel cells and zinc-air batteries.

Fuel cells offer a cleaner alternative to the combustion engine, electrochemically converting fuels into electricity, emitting only water and carbon dioxide in the process. Adoption of fuel cells has been hampered, in part, by the expense of the platinum-carbon catalysts used to facilitate the oxygen reduction reaction at the fuel cell cathode. The cost of the platinum accounts for about half the total price of a fuel cell. So chemists have been working for many years on alternative catalysts made of less expensive materials.

Nanostructured iron-carbon-nitrogen catalysts are a promising alternative, but not yet up to the task. “The stability is a problem, and performance rarely exceeds that of platinum,” says Liming Dai, who develops carbon nanomaterials at Case Western Reserve University. Hoping to improve their performance, chemists have been toying with the structure of these catalysts to maximize their total surface area and the exposure of active sites. One way to achieve this is with highly porous materials, which also allow electrolytes and reactants to move freely, making such materials good candidate catalysts.

Dai’s collaborator Ying Zhu, a chemist at Beihang University, wanted to try a new way of making a highly porous iron-carbon-nitrogen catalyst. Zhu was inspired by a YouTube video demonstrating the pharaoh’s snake, which she found to be an “amazing chemical reaction.” When a small mound of mercury thiocyanate powder is ignited, a series of reactions releases large amounts of gas, and the material forms elongated foamy ropes that rise from the flames on the reaction surface like snakes rearing their heads. The resulting “snake” material is a highly porous carbon nitride impregnated with toxic gases. Mercury thiocyanate is toxic, and the reaction produces gases including cyanogen and mercury vapor, so it’s no longer sold as a firework—but can produce an impressive display in a fume hood.

“Inspired by the ancient chemical reaction, we aimed to find safe and cost-effective materials for producing carbon foam for electrocatalysts,” Zhu says. Other versions of the reaction use sugar and baking soda—more kid-friendly ingredients. Zhu was inspired to adapt the reaction to nitrogen-, carbon-, and iron-containing catalyst precursors, with baking soda as a non-toxic foaming agent. To make their catalyst, Dai and Zhu ignited a combination of melamine (the nitrogen source), iron nitrate, sugar (the carbon source), and baking soda, which they expected would cause the material to foam as in the pharaoh’s snakes reaction. Indeed, the material grew into a snaky rope as it burned. They annealed the resulting material at 1000 °C to convert the carbon structures within from amorphous to crystalline forms, so that it would conduct electricity well.

The researchers crushed the catalyst and used it to make a fuel cell and a zinc-air battery. A methanol fuel cell built with the pharaoh’s snake catalyst operated at 0.9 volts, slightly better than platinum-catalyzed fuel cells. The group also tried the material in a zinc-air battery, which is powered by oxidizing zinc—and which is also stymied from commercial use because of expensive catalysts, typically ruthenium dioxide. Dai says the new material functioned comparably to ruthenium dioxide.

The catalyst material is made of carbon sheets and nanotubes doped with iron and nitrogen, with a large surface area providing plenty of exposure for catalytic sites, electron microscopy revealed. Other spectroscopy measurements showed that the material contains different types of active sites, including iron-nitrogen and nitrogen-carbon bonds.

Jean-Pol Dodelet, who develops catalysts at the National Institute of Scientific Research in Quebec, says the high degree of porosity of Dai and Zhu’s catalyst is an advantage. However, he says, the most important challenge in research on platinum-free electrocatalysts is not just to outperform the precious metal, but to do so in acidic solutions. Dai and Zhu’s catalyst beats platinum in an alkaline solution, but mature fuel-cell designs—such as those found in hydrogen vehicles—use acidic electrolytes. In acidic fuel cells, says Zhu, platinum-carbon catalysts still work better than the group’s snake material.

Dai says the group will work to solve this problem and improve the performance of the catalysts in other ways, as well as testing whether the pharaoh’s snake foaming method can also improve the porosity and performance of other electrocatalysts.

Shining a Light on a Chemiluminescent Success Story with ACS Central Science

Professor Doron Shabat of Tel-Aviv University knew he had a hit on his hands: his chemiluminescent compound could be used in biological probes for diagnosing diseases. This wasn’t a new idea, but his version was water-resistant and 3,000 times brighter than standard commercially available probes. He just needed to get the word out. That’s why he published his research in ACS Central Science.

The journal only publishes innovative research of the highest quality. Each article is heavily promoted through the journal’s own marketing and social media channels and it has already achieved a high partial Impact Factor. Moreover, ACS Central Science is fully open access, so readers wouldn’t need a subscription to learn about his work. Anyone with an internet connection could read “Opening a Gateway for Chemiluminescence Cell Imaging: Distinctive Methodology for Design of Bright Chemiluminescent Dioxetane Probes” for free and understand its potential. A few days after publication, that extra reach paid off. Dr. Urs Spitz, the CEO of a Swiss company called Biosynth, contacted Shabat about licensing his research.

Shabat says he wasn’t surprised that someone recognized the commercial value of his work. “It’s a very simple technology, but the application is clear,” he says. Yet the speed of the process was remarkable. The licensing agreement was the fastest in the history of the University of Tel Aviv. Now Shabat and Biosynth are partnering together through the university on additional research.

The idea of using luminescent materials to identify diseases isn’t new. Shabat first considered the idea about 20 years ago, during his postdoctoral period at The Scripps Research Institute. At the time, he couldn’t get the project to work, but when he came back to the idea last year with more experience under his belt, he was able to overcome the challenge of keeping water from extinguishing the light emission. “It was a trivial change,” to earlier designs he says. “Anyone could have made these chemical derivatives. But that happens in life sometimes. A little change makes the difference.”

The change to publishing in ACS Central Science for the first time made a difference too.  Shabat notes that he initially shared the research with another journal of high impact, but the paper never went to review. He says the difference is that ACS journals are edited by active researchers who could discuss the significance of his work. “ACS Editors are professional chemists, so when you make an argument with them, you’re speaking the same language,” he says.

“It’s a very fast system and very professional,” he adds. “And after the paper was accepted, the system worked very quickly to promote the paper. It’s simply the best experience I’ve had so far with publication.”

Engineered Silkworms Spin Unusual Amino Acids into Silk

Silk is smooth, strong, and biocompatible, making it a prized material for many applications. Scientists have tried all kinds of tricks to improve silk or imbue it with new properties: They have fed silkworms graphene or titanium dioxide to make stronger threads, fed them dyes to incorporate colors, and reprocessed silk to increase its elasticity. In the latest thread of the story, researchers have engineered silkworms to incorporate an extra amino acid, 4-azido-L-phenylalanine, into their silk. This amino acid serves as a ready target for functionalization reactions that could produce silks with a range of novel properties.

When an azidophenylalanine is incorporated into silk protein, the azido group (red) is a target for functionalization reactions.

Silk is mostly made of the silkworm protein fibroin. “Silk fibroin is mechanically tough and biocompatible,” says Hidetoshi Teramoto of the National Agriculture & Food Research Organization. His team’s goal is to develop methods to alter fibroin for biomedical applications—for instance, modifying silk with proteins that promote cartilage growth so it can act as a nurturing scaffold for regrowing damaged tissue. Adding unnatural amino acids, such as azidophenylalanine, into silk fibroin could broaden the chemical possibilities for modifying the protein. But “at the beginning of this project, the effects of unnatural amino acid incorporation on silkworms were quite uncertain,” Teramoto says. “Some people said worms might not be able to survive.”

Nevertheless, Teramoto and his team pressed on, seeing if they could convince silkworms to spin azidophenylalanine into silk. The azido groups in this amino acid are ripe targets for simple and quick click chemistry reactions. First, the researchers had to get the silkworm’s protein-making machinery to pick up azidophenylalanine in addition to the usual phenylalanine and incorporate it into fibroin. They generated a pool of less selective variants of tRNA synthetase, the enzyme that attaches phenylalanine to transfer RNA for transport to the ribosome. Co-author Kensaku Sakamoto of RIKEN Center for Life Science Technologies says they then used a bacterial screening system to rapidly identify cells that incorporated azidophenylalanine into their proteins. This process identified four variants of the synthetase that looked promising.

Next, the team created four transgenic silkworm strains, putting the variant synthetase genes into the worms so that only the silk glands would produce the enzyme, avoiding any toxicity that could come from incorporating azidophenylalanine into proteins in other parts of the body. Then they let the silkworms get to work spinning their cocoons. The team analyzed the resulting silk, finding that in two strains, over 6% of the phenylalanine had been replaced by azidophenylalanine. Then, the researchers demonstrated that the azidophenylalanine in the silk could be functionalized by conjugating the silk to fluorescent molecules using click chemistry. The cocoons glowed.

“This is the first time that a non-canonical amino acid has been engineered into a silkworm,” says Dieter Söll of Yale University. “There are many examples where people want to change the silk fiber. I think this a great step forward for the synthetic biology of silk.”

ACS Pharmacology & Translational Science Publishes Its First Peer-Reviewed Articles Free-to-Read

ACS Pharmacology & Translational Science launched February 14, 2018, and on May 9, 2018, published its first two peer-reviewed articles as Articles ASAP (As Soon As Publishable):

Stabilization of Cyclin-Dependent Kinase 4 by Methionyl-tRNA Synthetase in p16INK4a-Negative Cancer
ACS Pharmacol. Transl. Sci., Article ASAP
DOI: 10.1021/acsptsci.8b00001

Molecular Signature for Receptor Engagement in the Metabolic Peptide Hormone Amylin
ACS Pharmacol. Transl. Sci., Article ASAP
DOI: 10.1021/acsptsci.8b00002

These articles are free to read courtesy of ACS Publications. Both articles come from teams of researchers who are collaborating across disciplines and across continents to make discoveries that advance therapeutic intervention.

“I am excited by the publication of the first papers in ACS Pharmacology & Translational Science. In distinct ways, each provides an important example of how the application of interdisciplinary research can advance understanding of complex biological systems to provide a translational path for future therapeutic intervention,” wrote Editor-in-Chief Patrick Sexton in his May 9, 2018, Editorial “ Advancing Translational Understanding for Cancer and Obesity Therapy.”

Stabilization of Cyclin-Dependent Kinase 4 by Methionyl-tRNA Synthetase in p16 INK4a-Negative Cancer


The first peer-reviewed article published in ACS Pharmacology & Translational Science is by Dr. Sunghoon Kim of Biocon and Seoul National University, Korea, and his colleagues in other parts of that country, China, India, and the U.S. This group of researchers identified a novel mechanism for potential cancer intervention.

“This research first unveils an unexpected functional connection between the two key enzymes, namely, methionyl-tRNA synthetase (MRS) for translation and CDK4 for cell cycle control,” Kim said. “This finding also suggests the cancer-promoting interaction between these two enzymes as a new therapeutic point to control cancer. The pathological connection between MRS and CDK4 in cancer was validated in clinical analysis and the therapeutic potential of the MRS-CDK4 interaction was also shown by chemical inhibitors.“

Read “Stabilization of Cyclin-Dependent Kinase 4 by Methionyl-tRNA Synthetase in p16INK4a-Negative Cancer.”

Molecular Signature for Receptor Engagement in the Metabolic Peptide Hormone Amylin


ACS Pharmacology & Translational Science’s second peer-reviewed article–published just minutes after its first–is by Dr. Debbie Hay of The University of Auckland, New Zealand, and her colleagues in the U.K. and the U.S. Their work focuses on peptide hormone therapies for diabetes and obesity.

“The pancreatic peptide hormone amylin has many metabolic benefits, making targeting this system an attractive prospect for treating diabetes and obesity,” Hay said. “Our study is the first comprehensive analysis of how this long peptide engages its complex dimeric receptors, which now maps a path forward for novel amylin mimetic development. We are enthusiastic that this work will provide a valuable resource for others working with amylin and related class B peptide G protein-coupled receptor systems.”

Read “Molecular Signature for Receptor Engagement in the Metabolic Peptide Hormone Amylin.”

Why ACS Pharmacology & Translational Science?

“Why yet another journal, and why is ACS entering this space,” asked Editor-in-Chief Patrick Sexton in another May 9, 2018, Editorial “Introducing ACS Pharmacology & Translational Science.”

“The latter is easy: chemistry has forever been the foundation of new medicines and the intersection with pharmacology and the need to translate chemical discoveries into new medicines a fundamental axiom of most biological, and all medicinal chemistry programs,” Sexton explained. “Moreover, one needs only to look at recent awardees of the Nobel Prize in Chemistry to understand the fundamental relationship between chemistry and biology. The specific launching of ACS Pharmacology & Translational Science also recognizes a gap in publishing opportunities for authors bringing together interdisciplinary sciences and integrating molecular and biological studies to improve the translational relevance of their research.”

The lead authors of the journal’s first two peer-reviewed articles concur with the need for a major journal focusing on pharmacology and translational research supported by a leading publisher, and they were excited to be the first to publish in ACS Pharmacology & Translational Science.

ACS Pharmacology & Translational Science provides a perfect place for our research that includes comprehensive data on the fundamental and chemical biology nature of our research question in conjunction with translational research,” said Dr. Sunghoon Kim, lead author of the journal’s first published article.

“The recent launch of the journal ACS Pharmacology & Translational Science gave the perfect opportunity for us to showcase our work,” said Dr. Debbie Hay, lead author of the journal’s second published article. “ACS journals are well-respected and the addition of a pharmacology journal to the portfolio is a significant development, which we are very pleased to have been able to take advantage of.”
