A Tetragametic Woman

Posted 27 April 2014 by Joe Dramiga

A case report by Yu, et. al. in The New England Journal of Medicine narrates the discovery of a tetragametic woman; that is a woman derived from four different gametes, not just two. The 52-year-old came to the doctors' attention because she suffered from focal sclerosing glomerulonephritis and needed a kidney transplant. In preparation for kidney transplantation, she and her immediate family underwent a histocompatibility antigen blood test. The Histocompatibility Antigen Blood Test A histocompatibility antigen blood test looks at... Read more

Your Inner Ant: How Popularity on the Web arises by Trail and Error

Posted 12 April 2014 by Joe Dramiga

Every animal needs food and every animal likes food. Food is quite popular one could say. For foraging, some species like ants use the so-called trail-laying and trail-following behavior for finding the shortest path between a nest and a food source. The trail-laying and trail-following behavior consists of the following three basic principles: 1. Each time an ant moves, it lays a pheromone trail. 2. For finding its way, it senses its environment and a) follows existing trails, if there... Read more

Raw and Uncut 3: Red Cylindrical Confervae

Posted 24 May 2013 by Joe Dramiga

We sailed from Bahia. A few days afterwards, when not far distant from the Abrolhos Islets, my; attention was called to a reddish-brown appearance in the sea. The whole surface of the water, as it appeared under a weak lens, seemed as if covered by chopped bits of hay, with their ends jagged. These are minute cylindrical confervae, in bundles or rafts of from twenty to sixty in each. Mr. Berkeley informs me that they are the same species (Trichodesmium... Read more

Raw and Uncut 2: The Flashes of Fireflies

Posted 23 May 2013 by Joe Dramiga

All the fireflies, which I caught here, belonged to the Lampyridae (in which family the English glowworm is included), and the greater number of specimens were of Lampyris occidentalis. I found that this insect emitted the most brilliant flashes when irritated: in the intervals, the abdominal rings were obscured. The flash was almost co-instantaneous in the two rings, but it was just perceptible first in the anterior one. The shining matter was fluid and very adhesive: little spots, where the... Read more

In this way I hope to spark the interest and the curiosity of the reader to... Read more

The Clinical Utility of Pharmacogenomics for The Public Health Systems in Developing Countries

Posted 15 March 2013 by Joe Dramiga

Currently, pharmaceutical companies develop and test most drugs in Europe and North America, where they are licensed with efficacy rates as low as 30%. In contrast most drugs are usually marketed worldwide without any idea of how effective or safe they are in different population groups, and certainly without any regard for differences in SNP patterns or of other genomic variation that may correlate to differential drug responses between these groups. ...

Stirring Emotions with Science: The El Clásico of Evolutionary Theory

Posted 1 March 2013 by Joe Dramiga

The yellow press is known for stirring the emotions of the reader – good and bad - not so scientific journals like Nature. But once in a while a nature paper is published whose wider implications are not well received in certain circles and which makes a lot of people angry - for different reasons. ... Read more

Posted 18 February 2013 by Joe Dramiga
