Typically, if you want to understand the foundation of something, building from the ground up sounds like a sensible approach. However, researchers in Dr. Ni’s group at Harvard have taken this idea a step further by building molecules one atom at a time. The group’s goal is to better understand the minimal requirements and exact properties of chemical reactions. For comparison, while every chemistry class … Continue reading Building the Smallest Chemical Beaker
It is 2018, and we are well on our way towards curing cancer. Yet, as we look around, we find another nightmare haunting our society that is as formidable, if not more so, as it has been for centuries. That nightmare is opioid addiction. Overcoming opioid addiction is notoriously difficult, because of the excruciating symptoms associated with the withdrawal process, during which the only aid … Continue reading The FDA Approves the First Non-Opioid Drug to Ease Opioid Withdrawal Symptoms
Is this apple safe to eat? Did that course of antibiotics work? To answer these types of questions we often need to know how to find and count illness-causing bacteria. Several bacteria counting techniques already exist. However, these approaches are slow and sensitive to laboratory conditions. Sam Nugen and his team from Cornell University are streamlining this process using a type of virus called phages, … Continue reading Viruses to the Rescue: Can we use viruses to find bacteria in our environment?
What is the hardest thing you think scientists need to do in a lab? Organic chemistry may not be the first thing that comes to mind, but multi-step organic syntheses are easily ranked a top challenge, even among experienced chemists. Nevertheless, computer scientists surprised us again with artificial intelligence (AI) which, despite having less chemistry experience than the average high-schooler, could prescribe recipes with success. … Continue reading AI advises chemists on how to make complex molecules
These colorful fractions were obtained upon purifying a synthetic small-molecule through flash column chromatography. Though most of these were impurities (bright colors in organic chemistry is usually not a great sign), it served as a reminder to appreciate the beauty in the mundane and seemingly unimportant. Contributed by Carmen Sivakumaren, a graduate student in the Biological and Biomedical Sciences Program at Harvard Medical School. Continue reading Spectrum
One of our Instagram followers won a print of this beautiful image! Be sure to follow us on Instagram @SITN_Harvard for your chance to win some SciArt. This beautiful contribution from Don Pottle is best described by the legend himself: “A few years ago, I was asked by a maker of contact lenses to examine a few samples of used contact lenses. There was a suspicion of … Continue reading Crystaleyes
By Andrew Wong, a second year graduate student in the Applied Physics program at Harvard University. The increase in global energy demand and subsequent carbon dioxide emissions has driven advancements in renewable energy generation technologies such as wind turbines and solar cells. However, these technologies are inherently intermittent, and require robust energy storage devices. Inexpensive, large-scale energy storage systems such as aqueous … Continue reading The Light of Elendil in Shelob’s Lair
