Time to Reconsider the Color Red for Underwater Hulls. Jonathan R. Matias, Chief Science Officer of Poseidon Sciences Group, presented a paper at the 12th Annual World Congress of Ocean-2024 (WCO-2024) held at Aloft Novena Singapore. The paper explores the historical basis for the red color used on underwater hulls and how modern understanding of barnacle behavior challenges this tradition.
Reduction of human-vector contact is of epidemiological importance in malaria control. Repellents can be used to complement the existing intervention tools against malaria vectors. Thus, evaluation of efficacy of additional mosquito repellents and /or attractants is of great significance for personal protection tools against malaria vectors.
Understanding vector behavioral response due to ecological factors is important in the control of disease vectors. This study was conducted to determine the knockdown resistance (kdr)alleles, dieldrin resistance alleles, and entomological inoculation rates (EIRs) of malaria vectors in lower Moshi irrigation schemes for the mitigation of disease transmission. The findings of this study suggest that the homozygous and the heterozygous resistance present in rdl genes demonstrated the effect of pesticide residues on resistance selection pressure in mosquitoes. A better insecticide usage protocol needs to be developed for farmers to use in order to avoid excessive use of pesticides.
For the general public, the word ‘biocide’ is almost like a dirty word. Yet biocides remain an essential part of modern life, protecting the very same public that decry it from the host of bacteria and viruses in food, household items, such as cosmetics and toiletries, to swimming pools, paints and medical supplies.
Although preliminary in nature, these studies demonstrate the potential of catalytically active selenium as a biocidal alternative to conventional toxic biocides currently in the market today. With this validation of the biological actions of covalently bound selenium, a program is now in process to develop coatings technologies that would deposit selenium to iron surfaces and proppants. Covalently bound selenium coatings may represent the next generation of non-leaching, environmentally friendly biocidal technology for the hydraulic fracturing industry in the near future.
A new publication on Poseidon’s biological control method for malarial vectors was recently published in the journal Parasite & Vectors. This new method employs hibernating embryos of the annual fish to be transported without water and introduced in temporary pools. Upon hatching, the fish would decimate all the mosquito larvae in the seasonal pools.
Barnacles, Darwin and marine paint research. The article celebrates Charles Darwin’s 150th anniversary of writing the “Origins of Species” and Poseidon’s odyssey in marine paint sciences. This article was an expanded version of Poseidon’s 2009 Newsletter.

Rediscovery of seagrape Caulerpa lentillifera in the Gulf of Mannar and its mariculture. Once thought extinct in the Gulf, the seagrape, also referred to as umi budo, is high value seaweed for food use in Japan now found in the east coast of South India. Mariculture technologies were developed for this seaweed for later commercialization as an export commodity.
New shampoo additive to eliminate head lice from scalp hair. A novel use of the cooling agent, menthol propyleneglycol carbonate. Household and Personal Care Today, Suppl. Hair Care, April 2007, pp3-5. The article described clinical tests on the efficacy of MR-08 in deterring head lice from attaching to hair.
11th Congress on Marine Corrosion and Fouling, San Diego, California. The The poster presentation has been converted into an easy to read article about menthol and menthol analogues as barnacle repellent and a new method of coating plates with nontoxic resin to trap bioactives in a simulated coating environment.
