4:12 PM | Rough Day for Seattle Zoo
A young lion "escapes" at Woodland Park Zoo on same day as a controversial attempted move of elephants. "A second complaint asks the USDA to investigate the attempted transfer of Chai and Bamboo, which was aborted due to bad weather along the 2,000-mile route. The animals are being temporarily housed at the San Diego Zoo."

4:00 PM | „Triple contrast“ in der experimentellen und molekularen Ballistik
Wie versprochen, berichte ich heute von einer Methode, die wir erfunden haben, um mehr und bessere Ergebnisse aus experimentellen Beschüssen zu erhalten. Ich habe ja schon öfters über unsere Projekte zur molekularen Ballistik berichtet und ein zentrales Phänomen, das darin untersucht wird, ist der „Backspatter“ (dt. Rückschleuderspuren), also Spritzer von Blut und Gewebe, die aus…

3:30 PM | Argument for closed or open peer review?
Yesterday, I witnessed the most viral academic tweet I have seen since I opened my account two years ago. An anonymous reviewer suggested that male academics may publish more prolifically for the same reason that men tend to run faster than women. As if that's not enough, the reviewer then suggested that the paper could be improved by adding a male co-author to avoid biases. I am just going to assume that with the exception of this person, no one else on this planet thinks the same way. […]

3:30 PM | Lies, damn lies, and biological experiments
There's been quite a lot of coverage over the past week of stastistics and data representation in biology. A really well-written article in PLoS Biology  outlined the dangers of the oft-used bar chart and how it can be misleading/obscure real data, followed by many comments online and a note in this week's Nature.  As a physicist by training, I can hardly recall a single physics paper that used bar charts (however, this may just be my ignorance). In the biological sciences, it […]

1:54 PM | Choosing Primary and Control Reporters for Dual-Luciferase Assays
Dual-Reporter Assays give scientists the ability to simultaneously measure two reporter enzymes within a single sample. In dual assays, the activity of an experimental reporter is correlated with the effect of specific experimental conditions, while the activity of a control reporter relays the baseline response, providing an essential internal control that reduces variability caused by […]

1:42 PM | What’s the Answer? (woolly mammoth ORFs)
This week’s highlighted question was interesting to me in a couple of ways. It was a good question about the recent analysis of the woolly mammoth genome, making it a nice example of post-publication discussion. But mostly I just loved the chatter about issues and challenges around extinct organisms and their sequences. We are living […]

1:41 PM | Deep-Sea Sea Cucumbers! Transparent Guts Galore!
Wednesday (today) was the last day of the Okeanos Explorer's Oceano Profundo expedition, exploring the deep-sea habitats off Puerto Rico in the tropical Atlantic. In the next few months, they will transit through the Panama canal and onto Hawaii! Among the most commonly encountered of the animals they encountered were swimming sea cucumbers! I've written about swimming sea cucumbers here.  Most of the ones we saw were benthopelagic, which is to say that they live on the bottoms […]

11:53 AM | What explains the explosion of life during the Cambrian period?
For a more detailed look, check out my lecture on the subject. In a nutshell: a supercontinent, Rodinia, broke up a hundred million years before the Cambrian Radiation, leading to oceans becoming saturated with chemicals due to increased erosion from the continents. At the same time, the climate was becoming warmer. Together, these had two effects. … Continue reading What explains the explosion of life during the Cambrian period? → The post What explains the explosion of life […]

10:52 AM | Beyond the aptamer
Aptamers have been hailed as a new class of molecules with great potential to rival monoclonal antibodies in therapeutic, diagnostic, analytical as well as basic research applications. Described just over two decades ago, the field of aptamer technology received a great boost in 2004 after the first FDA approved drug, Macugen, to treat age relatedRead More

9:00 AM | The tail that doesn't wag: Why?
We know of countless traits that are due to mutations in single genes.  The same allele may not always confer exactly the same disease or other trait, because other genes or environmental factors may contribute, but for most purposes this additional variation is unimportant or at least tractable.  These traits appear in families in roughly Mendelian proportions, as has long been known.However, most traits including most of the common diseases, do not segregate in families. Instead, it […]

7:00 AM | When Montana Residents Lost Their Right To Free Speech
After the terrorist attacks in the US in 2001, the Patriot Act was enacted, causing some Americans to fear that their days of free speech were over. However, Montana residents had already experienced a frightening loss of their free speech rights in the early 1900s during World War I. At that time, Montana's new Sedition Law made it a crime to criticize the US government, including any opposition to the war. Even trivial infractions could be punished with fines and long prison sentences. The […]
