The Effects of Ultraviolet Light on Escherichia coli

Kodoth et al. | Sep 07, 2015

The Effects of Ultraviolet Light on <em>Escherichia coli</em>

In this study E. coli bacteria was exposed to small UV lights currently used in school laboratories to see the effect on colony growth. This project explores how UV radiation methods could be applied in common households to inhibit bacterial growth.

Development of a pH-sensing hydrogel wound dressing for early infection monitoring for all skin color types

L. Chong et al. | Sep 07, 2026

Development of a pH-sensing hydrogel wound dressing for early infection monitoring for all skin color types

This paper develops a gelatin-based hydrogel dressing infused with bromothymol blue dye that visibly changes from yellow to blue as wound pH rises from 5.0 to 8.0, signaling possible infection. The color shift was visually detectable and statistically significant across all six Fitzpatrick skin tones, suggesting a low-cost ($0.40/dressing) tool for early infection monitoring in settings with limited access to care.

The effects of a high-sucrose diet on the survival of Drosophila melanogaster from a bacterial infection

Warwick et al. | May 22, 2026

The effects of a high-sucrose diet on the survival of <i>Drosophila melanogaster</i> from a bacterial infection

Excess sucrose consumption has been associated with several health problems, including inflammation and potential negative effects on immune function. However, the exact relationship between sucrose intake and immunity remains unclear, especially during bacterial infections. This study examined how sucrose intake affected the survival of fruit flies following oral infection with the bacterial pathogen Serratia marcescens.

Influence of induction heating on static recrystallization kinetics of AISI 4130 steel

Chen et al. | Apr 30, 2026

Influence of induction heating on static recrystallization kinetics of AISI 4130 steel

This article investigates whether induction heating can speed up static recrystallization in AISI 4130 steel compared with traditional radiant heating. It was found that induction-heated samples recrystallized faster, softened more quickly, and showed earlier microstructural changes like grain nucleation and pearlite spheroidization, suggesting induction heating could be a more efficient alternative for industrial metal heat treatments.

The effect of lead oxide concentrations on the bioluminescence intensity of Panellus stipticus

Park et al. | Mar 02, 2026

The effect of lead oxide concentrations on the bioluminescence intensity of <i>Panellus stipticus</i>

Here the authors investigate the potential of the bioluminescent fungus Panellus stipticus to serve as a sustainable bioindicator for environmental lead contamination. Their findings demonstrate that higher lead concentrations cause a measurable decrease in fungal bioluminescence intensity over time suggesting that the fungus could be an effective tool for detecting lead in an environment.

Here the authors sought to find a more ethical and efficient way to temporary paralyze a cockroach by comparing the results of two methods. By comparing immobilization through immersion in cold water and exposure to a 100 % CO2 environment, they found that cockroaches could be immobilized and recovered significantly faster when exposed to CO2.
