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). Starting with the shape of the cells, the petals of a flower often have cone shaped cells. This shape helps to scatter more light giving… 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 similar to human tongues and noses. These artificial sensors are different from traditional sensors in that they don’t recognize individual molecules, instead, they recognize heterogeneous liquids… 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 problem and chemical/physical means of getting rid of them from the environment are either too expensive, not effective for low quantities of pollutants, or produce a lot of toxic waste. One solution is to use… Continue reading A Review of Microbial Biosorbents

Pu burning 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 (on an… Continue reading Pu burning in a molten salt fast reactor

Impacts of Biogeochemical Redox Processes

Biogeochemical Redox Processes and their Impact on Contaminant Dynamics SUMMARY: Reduction and oxidation reactions are the drivers behind many biological processes. Energy is both stored and transferred through these reactions. This article talks about the various redox reactions that can occur, both biotically and abiotically, and how that affects both biogeochemical cycles and contaminants. The… Continue reading Impacts of Biogeochemical Redox Processes
