Optimization of a Lithium Flow Battery to Increase Energy Storage

By Meghan Bialt-DeCelie Image acquired from: https://en.wikipedia.org/wiki/Wind_power_in_New_Zealand Figure 3: Windmills need reliable large-scale flow batteries to effectively store energy for later use.   The flow battery is a development in large-scale, renewable battery technology. It is often found attached to solar panels and windmills to collect the energy produced. However, it is unable to cost-effectively store large amounts of energy. Dr. Qing Wang, of the University … Continue reading Optimization of a Lithium Flow Battery to Increase Energy Storage

Your Robot Coworker Won’t Be Stealing Your Job After All

By Cerise Carey Is artificial intelligence as big of a threat to your job as it may seem? Researchers with the McKinsey Global Institute suggest not. Their research indicates that less than five percent of jobs and forty-five percent of general work activities could be automated. Jobs that could benefit from some activities becoming automated include physicians, financial managers, and senior executives. However, there are … Continue reading Your Robot Coworker Won’t Be Stealing Your Job After All

Confirmation of Quantum Mechanics

By Shannon Bohman Image acquired from commons.wikipedia.org Figure 1 This picture shows the physics building at Delft University of Technology in the Netherlands.   Netherland scientists of Delft University of Technology claimed to have proven quantum entanglement, the idea that if two particles’ spins are aligned, they can still influence each other at all times, no matter the distance between them. Two diamonds, each containing … Continue reading Confirmation of Quantum Mechanics

Engineering Escherichia coli cells to express Melittin in response to the detection of Pseudomonas aeruginosa

By Gurkamal Kaur, Janki Patel, Tenging Lama, Helen Liu, Gregory Poterewicz

Abstract

The growth of antibiotic resistance is quickly becoming a global public health concern. Infections caused by pathogenic bacteria are becoming increasingly difficult to treat due to the misuse, overuse and abuse of antibiotics. In addition, infections caused by some harmful strains of bacteria, particularly gram-negative bacteria, cannot easily be treated with antibiotics or other common forms of treatment. To combat this issue, E. coli were engineered to recognize the pathogenic bacteria Pseudomonas aeruginosa and produce the antimicrobial peptide melittin in response.  In order to do so, nonpathogenic E. coli were transformed with plasmids that control the production of melittin and the reception of communication signals from cells of Pseudomonas aeruginosa.

Researchers Create Antireflective Surface to Improve Solar Cells

By Ashwin Kelkar The advent of the solar panel has allowed us to harness the energy of the sun, similar to plants. However, unlike plants, solar panels run into a predicament; though we can utilize some of the sun’s rays, most waves end up being reflected off the surface of solar panels. This massive amount of reflected sunlight demonstrates how inefficient solar panels are, even … Continue reading Researchers Create Antireflective Surface to Improve Solar Cells

Pioneering X-Ray Techniques Used to Design More Efficient Batteries

By Ashwin Kelkar Have you ever wondered why your iPhone battery only lasts 3 hours instead of the projected 8? It can be frustrating to many people around the world, but it can be even worse when that battery is powering a pacemaker, a tool that allows people’s hearts to continue pumping blood. Imagine what would happen if a battery like this suddenly dies and … Continue reading Pioneering X-Ray Techniques Used to Design More Efficient Batteries
