Can you find artist among the scientific community?

Can you find artist among the scientific community? If you ask someone off the street if they consider a scientist an artist many may answer no; perceiving scientist as dull people in lab coats. This early March serval scientist at the Tufts Boston Campus where challenged to strut their artistic skills in the Sci-Art Competition helping break down the dull scientist persona people often perceive.

Jacob Klickstein, a Neuroscience student won first place with his “Brain Storm” piece. The piece was part of his current lab work in which he was looking at a cluster of iPSC-derived lower motor neurons stained for a cytoskeleton marker (TuJ1-cyan), a nuclear marker (dapi-blue) and a motor neuron-specific transcription factor (Hb9-red).

For second place, we had a tie between graduate students Ashlee Junior and Linus Williams. Ashlee is a Genetics student, her piece titled “INVADERS!” showcases Candida albicans filaments invading an agar plate.

Linus Williams is an Immunology student, his piece “A heart, broken by rejection”, is a Maisson’s Trichrome of a rejected mouse heart (Blue is fibrosis, red is muscle).

Eric Link is a technician in the Zeng lab. His piece “B-CHP Metatarsal on glass slide”, is a collagen hybridizing probe highlighting cartilage remodeling in the growth plate of a developing mouse metatarsal.

Quentin Bernard is a Microbiology student, his piece “Five, six, pick up Tick”, is an oxide’s scapularis tick stuck on its back before it was microinjected.

Alyssa DiLeo is a Neuroscience student. Her piece, “Possibilities: what went wrong with my western blot”, showcases the unfortunate results from a botched western blot.

Rachael Ryner is a CMDB student. Her piece, “Mermaid Mouse Brain”, is a fluorescent mouse brain section that has been immune-stained for beta-catenin and GABA in a CaMKII-Cre:Ai9 background.

Surendra Sharma is a CMDB student. His piece “The Dark Side of the Genome”, describes the long considered “dark matter” of genomes, regulatory noncoding RNAs like miRNAs and lncRNAs which are now recognized as key drivers and/or regulators of a variety of cellular processes.

Dominique Ameroso is a Neuroscience student. Her piece “Alien Astrocytes”, showcases astrocytes in culture – or an alien waiting for host.

Pragya Singh is a CMDB student. Her piece” A network of collagen”, exhibits collagen bundles forming in 3D, specifically a collagen1 gel as a result of LOXL2 treatment.

As scientists we have characteristics that by any dictionary definition would categorize us as artists. Naturally most scientists are curious. Our daily work requires us to be creative, take risks, and have a sense of passion for the work we do. The muse of a scientist lies in the continuous sense of adventure that comes from trying to uncover the unknowns in our projects. We don’t have to look too far for an example of an established scientist who struts his scientific muscles regularly. In our own Tufts community, our very own Dean, Dan Jay, is a visual artist who combines art and science to create pieces that express inspiration in science. This art competition was definitely a testament to our communities vibrant artistic abilities. Thank you to all those who participated and keep a look out for upcoming events and competitions.

2019 Nobel Prizes: Another Year Filled with Great Discoveries

This past December, the prestigious international Nobel prizes were awarded in recognition of academic, cultural and scientific advances. Before delving into this past year’s prizes, it seems only appropriate to take notice into how nominations to become a Nobel laureate occur. The process to select laureates begins in September when invitations are sent out to a select group to make nominations. The deadline for nominations is January 31 of the following year. Once nominations are in, there is a three-month process in which all nominations are being consulted on, with experts. After having consulted with experts, reports are written with recommendations during July and June. In September the Academy gets a report on final candidates and in October, after a majority vote, the Nobel Prize is announced. Bringing us full circle to this past December’s Nobel prize awards.

We begin with the Nobel Prize in Physics which this year was awarded for two separate discoveries, each of which I will comment on separately. The first, “the discovery of an exoplanet orbiting a solar-type star”, by Michel Mayor and Didler Queloz ushered in a new era for exoplanet astronomy. Before this, physicists wondered if there were other planets like ours in the solar system, and more deeply, wondered if there were planets just like our Earth that could sustain complex life. Since then, the interest in exoplanet astronomy has grown, and the tools at the disposal of scientists studying them have improved, with more exciting discoveries about exoplanets every year. The second, with equal value, “for theoretical discoveries in physical cosmology” by James Peebles is profound because his work attempts to understand the origins of the entire universe. A lot of active research in astrophysics depends on understanding what the initial conditions of the universe were like and wondering how the galaxies themselves came into existence. In building this article, it is worth mentioning many physicists felt the award for cosmology was bittersweet as it came a little too late for a certain well-known astronomer whose contributions to cosmology were also immense. Vera Rubin was an astronomer in the field of galaxy rotation rates that revealed the presence of dark matter. Dark matter is an essential component in the theories of cosmology, and many felt it sad to think her contributions did not get as much recognition from the Nobel committee when she was alive (She passed away in 2016).

The Nobel prize in Physiology or Medicine “for their discoveries of how cells sense and adapt to oxygen availability” was awarded to William G. Kaelin Jr, Sir Peter J. Ratcliffe and Gregg L. Semenza. Every cell in our body requires oxygen for basic metabolic and physiological functions. Several animals utilize oxidation reactions to power the conversion of nutrients from food into energy, making oxygen essential for supporting life. This discovery completed the full picture of oxygen sensing in cells that began back in 1931 with Otto Warburg’s discovery concerning the enzymatic basis for cellular respiration, and Corneille Heymans in 1938 for his findings on the role of the nervous systems respiratory response to oxygen. The question that loomed over many scientists in the current century, that this year’s Nobel finally addressed, was cellular adaptation to oxygen availability through gene expression. The ability to alter gene expression patterns to oxygen availability is essential during normal physiological events from embryonic development to even exercise. This variation also extends to pathological states such as cancer and infection. William Kaelin, Peter Ratcliffe and Gregg Semenza found that during normoxia a transcription factor that alters normal physiological processes is degraded via the ubiquitin proteasome system. However, during hypoxic states such as cancer or infection this transcription factor is not ubiquitin tagged and thus not sent to the proteasome for degradation leading to alterations in gene expression. The question these scientists helped to answer is a textbook question that we will likely see being taught in early biology classes. It is also something we will likely see being applied to new therapeutics as it paves the way for promising new strategies to fight anemia, cancer and many other diseases.

Lithium ion batteries are everywhere from your smartphones to devices used on the International Space Station. The Nobel prize in Chemistry “for the development of lithium-ion batteries” was awarded to John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino. The concept of lithium batteries has been around since 1991 and since their introduction to the field they have been revolutionary. The working principle of a battery is simple; it consists of two electrodes (metals like lithium) each connected to an electric circuit which itself is separated by an electrolyte that can accommodate charged species. Before we had lithium ion batteries, batteries relied on other metals such as copper, lead, and nickel. The main issue with the previous battery designs was that they were not rechargeable. Lithium on the other hand was rechargeable but prior to perfecting the design of the lithium battery, many worried it was too explosive. The current design of lithium batteries is not based on a chemical reaction as the designs preceding it were. Rather the new design relies on ions flowing back and forth between anode and cathode. This design is advantageous as it allows users to charge their batteries hundreds of times before the performance of the battery deteriorates. The work of these scientists is exciting as it introduces new power resources that other scientist can expand on in an era that seeks to lean away from fossil fuels. 

The last Nobel prize I will comment on is in Economics which was awarded to Abhijit Banerjee, Esther Duflo and Michael Kremer “for their experimental approach to alleviating global poverty”. According to the UN though, the global poverty rate has declined by half since the beginning of the twenty-first century, one in ten people in developing regions still live on less then two U.S. dollars. Many have attempted to help address the problem but have come short, describing the problem as too big. This year’s laureates went about addressing the crisis using a more strategic approach. The economists utilized a method familiar to many clinicians; they utilized Randomized Controlled Trials or RCTs. Instead of tackling poverty as a whole, they set up randomized trials in different locations in developing countries, in which they compared different groups with the same average character analyzing different things that contribute to poverty: education, health access, job availability, etc. By breaking down the problem, the economists were able to better define the needs of these developing countries in terms of resources they need, or have but aren’t utilizing. Today the field of developmental economics relies on field experiments as the gold standard for experiments done in order to give more valuable data.
