Second Award
Reverse osmosis (RO) has proven an effective method of water purification and has been widely implemented in much of the industrialized world. However, high production and energy costs of th…
Second Award
Parasitic weed Striga accounts for estimated yearly crop losses over $20 billion in the United States alone. Seeds of parasitic weeds germinate in response to signaling molecules called stri…
Second Award
Atherosclerosis and subsequent cardiovascular disease causes nearly one-third of all deaths in the world. Unfortunately, atherosclerosis commonly remains asymptomatic for decades, and is pro…
Second Award
Point-of-care (POC) diagnostics serves to deliver rapid and robust results in resource poor settings; however, current tests have been hindered by qualitative “yes-or-no” results. The purpos…
Second Award
Increases in world population have required improved agricultural yields. Cellulose binding domain IV (CBD), the non-catalytic domain of a novel family of carbohydrate-binding hydrolases, ha…
Plant Biology
Second Award
Objectives/Goals California undergoes cycles of severe drought followed by El Niño for several years. The objective of this study was to determine which soil amendments, or combinations of b…
Second Award
The purpose of this project was to build muffler that serves two purposes; attenuating exhaust noise and increasing performance. Computational fluid dynamics software was used to create mode…
Biochemistry/ Molecular Biology
Second Award
Objectives/Goals It has recently been discovered that B7-H4 is a protein in only low amounts in normal tissues but highly concentrated in over 90% of cases. Utilizing the monoclonal antibody…
Second Award
Biohydrogen generated from algal cultures can be an effective solution as cleaner alternative fuel to reducing greenhouse gas emissions. Most of the related research is focused on limited st…
Microbiology (General)
Second Award
Objectives/Goals My project aims to improve the efficiency of efflux pump inhibitor Naphthylmethyl Piperazine (NMP). Methods/Materials I performed my tests in New England Biotech's C2992 E.…
Electronics & Electromagnetics
Second Award
Objectives/Goals This experiment examined the effects of pipelining on the speed of CPUs. The goal was to test which CPU type (pipelined and not pipelined) was faster at executing programs.…
Second Award
Electrical discharges in liquids have been used for water disinfection and decontamination, nanoparticle production, and many other chemical and biological applications. Gas bubbles are intr…
Second Award
Activation of aortic vascular smooth muscle cells (VSMCs) by the hormone Angiotensin II (Ang II) is a critical event in the development of atherosclerosis and hypertension. In addition, enha…
Second Award
Spinal cord injuries (SCI) or illnesses like ALS or MS cause disabilities that make people dependent on a wheelchair and in their etiopathology are robbed of any movement at all. Our project…
Second Award
A robot control system was developed that could be taught tasks through reinforcement learning. The system, nicknamed “Fido”, was designed to be universal regardless of inputs and outputs, r…
Second Award
Both biochar and layered double hydroxides (LDH) have received substantial attention for their abilities to adsorb chemical contaminants, yet little research has been reported on LDH/biochar…
Chemistry
Second Award
Objectives/Goals Tea, which is a popular drink, is a great source of antioxidants for the body. Many people put additives like milk and sugar in their tea. The purpose of this project was to…
Microbiology (Medical) (Junior Division Only)
