New and Exciting in PLoS ONE

There are 49 new articles in PLoS ONE this week. Here are some titles I found interesting: Echolocating Bats Cry Out Loud to Detect Their Prey: Echolocating bats have successfully exploited a broad range of habitats and prey. Much research has demonstrated how time-frequency structure of echolocation calls of different species is adapted to acoustic…

My picks from ScienceDaily

Single-celled Bacterium Works 24/7: Researchers at Washington University in St. Louis have gained the first detailed insight into the way circadian rhythms govern global gene expression in Cyanothece, a type of cyanobacterium (blue-green algae) known to cycle between photosynthesis during the day and nitrogen fixation at night. How Birds Navigate: Research Team Is First To…

As we mentioned just the other day, studying animal behavior is tough as “animals do whatever they darned please“. Thus, making sure that everything is controlled for in an experimental setup is of paramount importance. Furthermore, for the studies to be replicable in other labs, it is always a good idea for experimental setups to…

Everything Important Cycles

Microarrays have been used in the study of circadian expression of mammalian genes since 2002 and the consensus was built from those studies that approximately 15% of all the genes expressed in a cell are expressed in a circadian manner. I always felt it was more, much more. I am no molecular biologist, but I…

…then we take Berlin

Just landed in Berlin. Flew with JAT for the first time in decades. The best flight ever. I guess their pilots, after getting some real dogfight combat flying experience find piloting a B-737-300 way too easy…

ClockQuotes

The last time somebody said, ‘I find I can write much better with a word processor’, I replied, ‘They used to say the same thing about drugs.’ – Roy Blount, Jr.

Two interesting papers came out last week [from the Archives – click on the clock logo to see the original post], both using transgenic mice to ask important questions about circadian organization in mammals. Interestingly, in both cases the gene inserted into the mouse was a human gene, though the method was different and the…

This morning I had to get up early to go and give my interview for Radio Belgrade 1, at the same time when my Radio Belgrade 2 interview was on. This one will be broadcast in ten days or so. All the radio interviews will be recorded and placed on the web so I can…

After watching the show jumping classes and chatting with my horsey friends, I went back to the city center, explored the place and saw that unlike most other types of stores, the bookstores are still there where I remembered them, not replaced by new boutiques and cafes, surviving the decades of hyperinflation, sanctions, wars and…

Yesterday I went to the Belgrade Racecourse and the barns and was happy to meet many of my old friends, including my old trainer (with Professor Steve Steve below) as well as some good new kids, including two sisters who used to own and ride my old horse. There were two small show jumping classes…
