1:00 PM | Right Turn: Blockbuster toy or super (silly) biomaterial?
. Signals’ mandate is to bring you, dear reader, blogs about stem cells, commercialization and biomaterials, but lately there hasn’t been much of the latter; therefore, I’ve decided to try to fill that gap. But before you get too excited, I am in no way an expert on biomaterials, despite my affection for them (and...Read more

1:00 PM | Luck is on their side in “bad luck” cancer study
. Before you read my blog, I recommend that you first read Sara Nolte’s blog “Bad luck, bad science, or bad reporting?” In it, Sara does an excellent job explaining and commenting on Drs. Cristian Tomasetti’s and Bert Vogelstein’s study “Variation in cancer risk among tissues can be explained by the number of stem cell...Read more

10:23 PM | Beauty Is Not In The Eye Of The Beholder
“Celebrity-endorsed” beauty products are not a construct initiated by modern society. Ancient medical authors often claimed that someone famous had used their products, such as Cleopatra or Thaïs in order to make their concoctions sound more appealing. Aetius of Amida (sixth century CE) related the recipe of a famous “soap used by the Patrician Pelagia […]

2:00 PM | Fixing ‘Leaky’ Blood Vessels in Severe Respiratory Ailments and Ebola
When you get an infection, your immune system responds with an influx of inflammatory cells that target the underlying bacteria or viruses. These immune cells migrate from your blood into the infected tissue in order to release a cocktail of pro-inflammatory proteins and help eliminate the infectious threat. During this inflammatory response, the blood vessel barrier becomes “leaky.” This allows for an even more rapid influx of additional immune cells. Once the infection resolves, […]

10:39 PM | ‘Groovey’ Asymmetries
Our brains are three times the size of those of chimps, yet anatomical features possessed only by humans have been extremely difficult to pinpoint. It is clear that the two species’ brains are composed differently in the areas that control social skills and language. So far, the predominant observed difference has been in a region […]

4:25 PM | How Often Do Books Mention Scientists and Researchers?
Here is a graphic showing the usage of the words "scientists", "researchers", "soldiers" in English-language books published in 1900-2008. The graphic was generated using the Google N-gram Viewer which scours all digitized books in the Google database for selected words and assesses the relative word usage frequencies.   (You can click on the chart to see a screen shot or on this link for the N-gram Viewer) It is depressing that soldiers are mentioned more frequently than scientists or […]

6:10 PM | Sharing Is Caring
Biology textbooks commonly talk about how bacteria can carry out horizontal gene transmission, that is, transfer rings of free DNA called plasmids between different bacterial cells. This allows them to pass traits like antibiotic resistance from one bacterium to the next. Until recently, this was the only recorded case of DNA transmission between cells. Now, […]
