Rotifers Paralyzing Schistosomes

sciencewithevie

A rotifer-derived paralytic compound prevents transmission of schistosomiasis to a mammalian host SUMMARY: Researchers discovered that a new molecule produced by the rotifer, Rotaria rotatoria, paralyzes cercariae. Cercariae are the free-living/infectious stage of the flatworm Schistosoma, the cause of schistosomiasis. R. rotatoria live on the shell of freshwater snails and secrete a compound scientists have… Continue reading Rotifers Paralyzing Schistosomes

Electronic Tongues

sciencewithevie

A Versatile Electronic Tongue Based on Surface Plasmon Resonance Imaging and Cross-Reactive Sensor Arrays-A Mini-Review SUMMARY: Scientists are trying to create electronic tongues (eT) and noses (eN) that act like human tongues and noses. These artificial sensors are different from traditional sensors in that they don’t recognize individual molecules, but heterogeneous liquids and gases. In… Continue reading Electronic Tongues

A Review of Microbial Biosorbents

sciencewithevie

A New Strategy for Heavy Metal Polluted Environments: A Review of Microbial Biosorbents SUMMARY: Heavy metal pollution is a serious environmental problem and the chemical/physical means of getting rid of them are either too expensive, not effective for low quantities of pollutants, or produce a lot of toxic waste. One solution is to use microbes… Continue reading A Review of Microbial Biosorbents

Silver Dressing and Bacteria

sciencewithevie

Wound management in an era of increasing bacterial antibiotic resistance: A role for topical silver treatment(NOT OPEN ACCESS) SUMMARY: One way of fighting antibiotic resistant bacteria is to prevent them from growing in the first place. This article looks at three different types of silver dressing, intended to do just that: silver nitrate, silver sulfadiazine,… Continue reading Silver Dressing and Bacteria

Beaming Naphthalene Part 2

sciencewithevie

Amino Acids produced from the ultraviolet/extreme-ultraviolet irradiation of naphthalene in a H2O+NH3 ice mixture SUMMARY: This experiment starts quite similarly to “Beaming Naphthalene 1”, but after exposure to UV light, researchers scraped off the residue (there was no scraping of the residue in “Beaming Naphthalene 1”), hydrolysis performed (reaction with water) and products identified with… Continue reading Beaming Naphthalene Part 2

Beaming Benzene and Naphthalene

sciencewithevie

N- and O-Heterocycles Produced from the Irradiation of Benzene and Naphthalene in H2O/NH3-Containing Ices SUMMARY: While pyrimidines have been found on space rocks (carbonaceous chondrites), researchers wanted to see if they can produce different types of heterocyclic molecules in the lab by beaming benzene and naphthalene (both are cyclic organic compounds that can open, substitute… Continue reading Beaming Benzene and Naphthalene
