Environmental Engineering
Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals with strong carbon-fluorine bonds that resist breakdown in the environment and are associated with serious health effects,…
ISEF · 2026
Earth and Environmental Sciences
In the past 20 years, flooding has been the most common natural disaster worldwide, accounting for 43% of all recorded events, and causing tremendous loss of life and property. The North Car…
ISEF · 2026
Robotics and Intelligent Machines
Autonomous drone navigation in GNSS-denied environments is challenging because conventional systems rely on rigid spatial representations, require environment-specific training, or are too c…
ISEF · 2026
Computational Biology and Bioinformatics
Alzheimer's disease (AD), a multifactorial neurodegenerative disorder, is associated with amyloid-beta aggregation, tau hyperphosphorylation, neuroinflammation, apoptosis, and endoplasmic re…
ISEF · 2026
Biochemistry
Drug repositioning—the repurposing of existing drugs for new applications—provides high safety but is still limited in gene therapy. As gene therapy research grows globally, safe genome engi…
ISEF · 2026
Chemistry
With the advancement of vaccine technology, the need for safe and effective adjuvants has become increasingly important. While QS-21 is a clinically established adjuvant, it alone cannot ful…
ISEF · 2026
Earth and Environmental Sciences
Access to safe drinking water remains a pressing global challenge, with millions exposed to heavy-metal contamination each year. At the same time, fertilizer runoff degrades water quality th…
ISEF · 2026
Physics and Astronomy
Black hole X-ray binaries contain a black hole that accretes gas from a companion star, producing bright X-rays. By fitting the X-ray spectra with astrophysical models, we can estimate key p…
ISEF · 2026
Animal Sciences
There have been calls for replacing synthetic food dyes, including Yellow 5 (tartrazine), with natural dyes, including beta-carotene extract from the microalgae Dunaliella salina. The projec…
ISEF · 2026
Mathematics
Classical graph coprime labelings given by Gallian (2009) are static and unchanging, thus inadaptable to real-world systems. We introduce dynamic coprime labeling (DCL), a novel extension of…
ISEF · 2026
Physics and Astronomy
Kerr black holes, or rotating black holes, are central to understanding spacetime curvature around massive rotating bodies; the Penrose process offers a theoretical framework for extracting…
ISEF · 2026
Computational Biology and Bioinformatics
In all known life, proteins are synthesized on ribosomes. This delicate biochemical process is regulated by a multitude of factors, one of them being the Nascent-polypeptide Associated Compl…
