How Fireflies Get It On

Sunday, February 7th, 2016

Sara Lewis reduced her discoveries about firefly sex to 24 seconds, and then to seven words. She performed this, as a 24/7 Lecture, at the 2015 Ig Nobel Prize ceremony:

A year before that, Lewis performed a longer version — about thirteen minutes long — as a TED talk:

Appreciation: “No index…, no table of contents…, no order”

Saturday, February 6th, 2016

“There is no index at the back, no table of contents at the front, and the subjects covered are not arranged in alphabetical, or any other, order. A hotchpotch is a hotchpotch, but not being able to locate or then re-find anything slowly drove me insane with fury. ”

That’s one of the delightful passages in the “Indexes Reviewed” section of issue number 3, of volume 33 — the September 2015 issue — of the journal The Indexer. the international journal of indexing.

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

Monday, February 1st, 2016

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.”
