Controlling Gene Expression With Hydrogen Peroxide “Switches”

Hydrogen peroxide doesn’t just come in bottles from the drugstore – the human body makes it as well. Now researchers from North Carolina State University have found a way to use naturally occurring hydrogen peroxide inside cells to switch on gene expression. Their method also serves as a highly sensitive hydrogen peroxide detector, which may…

Researchers Use Light to Switch On Gene Expression

Imagine being able to control genetic expression by flipping a light switch. Researchers at North Carolina State University are using light-activated molecules to turn gene expression on and off. Their method enables greater precision when studying gene function, and could lead to targeted therapies for diseases like cancer. Triplex-forming oligonucleotides (TFOs) are commonly used molecules…

Mechanism Behind Capacitor’s High-Speed Energy Storage Discovered

Researchers at North Carolina State University have discovered the means by which a polymer known as PVDF enables capacitors to store and release large amounts of energy quickly. Their findings could lead to much more powerful and efficient electric cars. Capacitors are like batteries in that they store and release energy. However, capacitors use separated…

Researchers Develop Better Control for DNA-Based Computations

A North Carolina State University chemist has found a way to give DNA-based computing better control over logic operations. His work could lead to interfacing DNA-based computing with traditional silicon-based computing. The idea of using DNA molecules – the material genes are made of – to perform computations is not new; scientists have been working…

Compound May Help in Fight Against Antibiotic-Resistant Superbugs

North Carolina State University chemists have created a compound that makes existing antibiotics 16 times more effective against recently discovered antibiotic-resistant “superbugs.” These so-called superbugs are actually bacterial strains that produce an enzyme known as New Delhi metallo-β-lactamase (NDM-1). Bacteria that produce this enzyme are practically impervious to antibiotics because NDM-1renders certain antibiotics unable to…

NC State University Aims to Increase Diversity in Geosciences

A new initiative from North Carolina State University will address the need for increased awareness of, and participation in, geosciences fields from traditionally underrepresented groups. NC State has received a five-year, $1.2 million grant from the National Science Foundation to increase diversity in geoscience fields such as geology, marine science and atmospheric sciences. The grant will…

Supernova Solved

In 185 A.D., Chinese astronomers recorded a bright “guest star” in the night sky. By the 1960s, astronomers figured out that the guest star was in fact a supernova, and identified the remains of the stellar explosion. And in 2011, a team of astrophysicists led by NC State researchers solved the mystery of what caused this…
