Chemical Sensors Attractively at One’s Fingertips

Thursday, February 4th, 2016

Chemists, some of them, do pay attention to their fingernails. A team at the University of California, La Jolla (an institution that seems to exist on April 1, when it apparently migrates from San Diego), has paid special attention. Details are in their study:

A Wearable Fingernail Chemical Sensing Platform: pH Sensing at Your Fingertips,” Jayoung Kim, Thomas N. Cho, Gabriela Valdés-Ramírez, Joseph Wang, Talanta, vol. 150, April 1, 2016, pp. 622–628. The authors explain:

“Here we introduce the first demonstration of a wearable fingernail chemical-sensor platform. The objective of this work is to demonstrate the first example of a wearable chemical sensor on a fingernail platform. Fingernails represent an attractive wearable platform, offering portability and possibility to merge technology with beauty and fashion products, thus reflecting growing trends toward more stylish wearable devices. While several efforts have been made on developing fingernail-based sensors, none has been developed for chemical sensing.”

Here’s further detail from the study:

Nominative Determinism: Dr. Forrest on Trees

Landscape-Trees-ShrubsThis book presents a horticultural overview of the main plant families of trees and shrubs from temperate regions that are cultivated in urban and rural landscape schemes. Most of the plants used come from a limited number of plant families and within these families, certain genera contribute very significantly. The largest chapter in the book describes 37 plant families according to their identification, functional use and management in landscape schemes. With this information readers will be able to assess the suitability of species and prepare planting designs for prevailing sites.”

Author: Dr. Mary Forrest, School of Biology and Environmental Science, University College Dublin, Ireland.

“Imagine if the window were made of ants…”

Sunday, January 31st, 2016

Ig Nobel Prize winner David Hu researches many questions that involve biology AND mathematics AND physics. And often, fluid dynamics. In this video, he confides, concisely, some of the biophysical ways that ants survive perilous, quickly-changing physical conditions:

The 2015 Ig Nobel Prize for physics was awarded to Patricia Yang [USA and TAIWAN], David Hu [USA and TAIWAN], and Jonathan Pham, Jerome Choo [USA], for testing the biological principle that nearly all mammals empty their bladders in about 21 seconds (plus or minus 13 seconds).

NOTE: David Hu will be one of the stars of the London shows on the upcoming Ig Nobel Eurotour, in March 2016.

Colin Raston tells of Un-boiling an Egg, and the Ig Nobel Prize

Saturday, January 30th, 2016

Colin Raston tells how he and colleagues found a way to partially un-boil an egg, and of how this led to an Ig Nobel Prize, in this Flinders University video:

The 2015 Ig Nobel Prize for chemistry was awarded to Callum Ormonde and Colin Raston [AUSTRALIA], and Tom Yuan, Stephan Kudlacek, Sameeran Kunche, Joshua N. Smith, William A. Brown, Kaitlin Pugliese,Tivoli Olsen, Mariam Iftikhar, Gregory Weiss [USA], for inventing a chemical recipe to partially un-boil an egg.
