Rotifers Paralyzing Schistosomes

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

Anchoring like octopus

Anchoring like octopus SUMMARY: In this experiment, scientists tried to reproduce an anchoring mechanism modeled after octopus suckers. There were a few important aspects they wanted to mimic: the softness of the suckers so that suction could be maintained, even on rough surfaces. And the ability to sense proximity and tactile stimuli. They ended up… Continue reading Anchoring like octopus

The physics of pollinator attraction

The physics of pollinator attraction SUMMARY: This article focuses on the physical properties of plants that have evolved to help them select the appropriate pollinators and discourage non-pollinators (nectar stealers). The first feature the article addresses is the shape of the cells. Flower petals often have cone-shaped cells to help scatter more light. This gives… Continue reading The physics of pollinator attraction

Electronic Tongues

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

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

Using Pu in a molten salt fast reactor

A disruptive approach to eliminating weapon-grade plutonium – Pu burning in a molten salt fast reactor SUMMARY: This study looked at the efficiency of several types of nuclear reactions: molten-salt reactors, light water reactors, and fast reactors. Using a program (written in Python), scientists looked at the data from each type of reactors and compared… Continue reading Using Pu in a molten salt fast reactor
