8:19 PM | Save the Tasmanian Devil
  The Tasmanian devil is famed for its shrieking call and fierce temperament, which reportedly terrified Europeans colonising Australia back in the 19th century. Tasmanian devils are now endangered in the wild. One of the reasons for this is the spread of devil facial tumour disease (DFTD), an aggressive transmissible cancer. DFTD has a 100%…

Cheetahs use film vehicle as look-out post The Earth Touch crew filming in the Serengetti got much more than they bargained for when some cheetahs decided to use the roof of the vehicle as a lookout post.

The Most Radioactive Places on Earth Who on Earth is exposed to the most ionizing radiation? I’m filming a documentary for TV about how Uranium and radioactivity have shaped the modern world. It will be broadcast in mid-2015, details to come. The filming took me to the most radioactive places on Earth (and some places, which surprisingly aren’t as radioactive as you’d think). Chernobyl and Fukushima were incredible to see as they present post-apocalyptic landscapes. I also […]

Bioethicist Daniel Sulmasy revisits the prolonged death of Eleanor Roosevelt in a new case study, and talks about how the field of clinical medical ethics has changed the way physicians honor their patients' wishes.

6:19 PM | Hard to know what to say about the torture report so leave it to Tom Tomorrow
The release of the summary of the torture report more or less tells us something most people already knew, so it's hard to know how to respond or comment. Only a real Pollyanna would think the USA doesn't have numerous secret closets filled with dirty-dealing skeletons. The only real surprise was that this report acknowledges as much of the dirty dealings as it does. Even still it won't make a big impression on the "USA is number 1" crowd; us cynics weren't disappointed, again. Everyone […]

6:06 PM | Making the complex less complicated: Scientists create a simple, functional ion transporter
Scientists have designed a stripped-down version of a protein that carries certain ions across a membrane. In doing so, the scientists have shown that the large, complex transporters found in all living things actually operate on simple principles. They’ve also demonstrated that we now know enough about these molecular machines to design them from scratch. […]

4:17 PM | Studying species you like
As an undergraduate, one of my professors recommended that you should study organisms that you like. In a new paper, Ferry and Shiffman talk about not getting that advice... in fact, they received advice that was about 180° away from it:Scientists should not, according to this instructor while singling out DS and a student studying marine mammals as examples, pick a species that they “like” and then come up with a research question related to it. Author LF had a similar […]

3:30 PM | Forensische Phylogenetik – Woher kam das Virus?
Erinnert sich noch jemand an die vor einigen Jahren umgehende Angst vor HIV-verseuchten Nadeln, die angeblich jemand in Kinosesseln deponiert hatte? Das ganze war glücklicherweise nur ein Hoax, doch hier in der Rechtsmedizin sind Infektionskrankheiten als Waffe durchaus nicht unbekannt. Immer einmal wieder kommt es vor, daß zum Beispiel Heroinabhängige, die untereinander in Streit geraten…

3:21 PM | From naïve pluripotency to chimeras: a new ethical challenge?
This article by Insoo Hyun was first published in  Development. Also read the companion ethics article here.   In recent years, there has been much interest in the prospect of generating and using human stem cells that exhibit a state of naïve pluripotency. Such a pluripotent state might be functionally confirmed by assessing the chimeric contribution of these cells to non-human blastocysts. Furthermore, the […]

3:15 PM | Ethical considerations in chimera research
This article by Göran Hermerén was first published in  Development. Also read the companion ethics article  here.   The development of human pluripotent stem cells has opened up the possibility to analyse the function of human cells and tissues in animal hosts, thus generating chimeras. Although such lines of research have great potential for both basic and translational science, they […]

1:00 PM | Evolution shaped the internal beauty of plants
As plants embraced the terrestrial lifestyle, they underwent a range of adaptations to increase their size and stature as well as to facilitate transport of water and/or solutes. These vegetative innovations, which include the development of vascular and mechanical tissues, increased the anatomical complexity of plants. Such specialization is reflected in the design of the […]
