4:00 PM | Inflorescences take centre stage
Annals of Botany has a new special issue in Free Access: Inflorescences. It’s a useful reminder to me of another area of Botany I need to read more about. For a start, I think I’ve said elsewhere that inflorescences are the structures where there are multiple flowers on a plant and not just a single […]

3:56 PM | Tips for Successful Dual-Reporter Assays
Recently, one of my fellow bloggers described some of the advantages of using dual-reporter assays (including our Dual-Luciferase®, Dual-Glo® Luciferase and our new NanoDLR™ assay debuting soon). These assays are relatively easy to understand in principle. Use a primary and secondary reporter vector transiently transfected into your favorite mammalian cell line. The primary reporter is commonly […]

3:14 PM | Ebola Crisis Hackathon
The Ebola Virus has killed almost 6000 people in West Africa since Dec 2013Ebola has infected over 15000 people in West Africa since the start of the current outbreak in December 2013. The disease has an estimated case fatality rate of about 71%, and efforts to control the outbreak have been hampered by the political and economic situations in the countries affected (so far almost all cases have occurred in Liberia, Sierra Leone and Guinea). Problems have included, but are certainly not limited […]

3:10 PM | Learning from Fisheries
Sometimes we tend to forget that all our efforts to build an all-encompassing library of DNA Barcodes generate very valuable byproducts. Probably one equally important legacy is the huge number of DNA extracts and in many cases the associated tissue samples that stored in various places and hopefully available to future generations.Tissue samples today are either preserved in formalin, at temperatures between - 80 and - 90 C, or in liquid nitrogen, at about 193 C. The formalin method works well […]

2:00 PM | Philosophy begins where physics ends, and physics begins where philosophy ends
Richard Feynman - philosopher (Image:WashU)A few months ago, physicist Sean Carroll has some words of wisdom for physicists who might have less than complimentary things to say about philosophy. The most recent altercation between a physicist and philosophy came from Neil deGrasse Tyson who casually disparaged philosophy in a Q&A session, saying that it can be a time sink and it doesn’t actually provide any concrete answers to scientific questions. Now I am willing […]

10:15 AM | Helicobacter pylori and stem cells in the gastric crypt
Last Friday, the 4th Integrated Mathematical Oncology Workshop finished here at Moffitt. The event drew a variety of internal and external participants — you can see a blurry photo of many of them above — and was structured as a competition between four teams specializing in four different domains: Microbiome, Hepatitis C, Human papillomavirus, and […]

As a follow up to my recent posts on lamella scale counts on toepads, I thought I would share a tutorial I created for measuring toepad length and width using the program ImageJ. ImageJ is a free, open-access program that allows you to perform a suite of analyses on pictures or scans. I hope this […]

9:27 AM | The Victorians and the case of the dead houseplants
Imagine yourself in the 1800s, Queen Victoria has been on the throne for a few years now. You've probably heard of a chap called Charles Darwin who's book about his jolly in the Beagle has been making the rounds. And you've probably heard of a new-fangled bicycle that allows you to pedal yourself around rather than pushing along with your feet on the ground.Over the past few years gas lighting has been introduced, first in London and then Preston, Lancashire, but now it's gradually appearing in […]

Scientists recently sequenced the genomes of 17 of the oldest people alive in the USA to see if their genes could tell us the key to slowing ageing. The people studied were all supercentenarians – over 110. When the paper was published in November 2014, there were 74 supercentenarians known in the world. Sixteen of […]

8:00 AM | The Bizarre Practice Of Staging Civil War Photographs
During the American Civil War, photography was just coming into its heyday. For the first time, civilians were able to see the horrors of the battlefield---days, weeks, and months after the fighting. Photographers, most notably Alexander Gardner, saw their documentation of the battles as a duty to capture the most moving images they could. And when they couldn't find the right shot, they'd make it by moving the bodies and occasionally adding props. The post The Bizarre Practice Of Staging […]
