The Bottleneck Years by H.E. Taylor Chapter 97 Table of Contents Chapter 99 Chapter 98 The Second Day, March 21, 2061 On Monday morning, I watched the second session of Jon’s trial alone in my office at CCU. I didn’t have a class until mid-afternoon, so time was not an issue. Jon was led into…

  It is not surprising that Biwa salmon (image above), a subspecies of Oncorhyncus masou, do not adapt to seawater very well after having been landlocked in Lake Biwa, Japan for the last 500,000 years or so.  Researchers from Hokkaido University and Shiga Prefecture Fishery Experiment Station in Japan wanted to know what caused the salmon to…

New research published in PLOS Genetics shows that starving C. elegans (Caenorhabditis elegans) during the late larval stage of development when the worms are undergoing tissue growth and formation halts cellular activity at previously unknown checkpoints in their development. These findings show that nutrition is an important cue to signal whether or not the worms should…

Day 3 — The sun comes out

The sun came out and I was called out of a session, so I took advantage of the sunshine, after three days of grey and drizzle, to see the outdoor booths set up all around the buildings in the Carlsberg complex, here. In fact, in conjunction with this main festival of science, the city of…

Aside from the actual science, I am learning that 1) Copenhagen can be quite cold in the summer and 2) that the natives here are quite friendly. More than once people on the street have stopped to help me find my way. And the streets are full of people — walking, riding bikes, taking buses.…

Day 2 — engineering life

Today we get to the science and the issues surrounding it. Karl Deisseroth gave the first keynote lecture. For anyone who’s been asleep the past few years, Deisseroth’s lab at Stanford is at the cutting edge of a new kind of brain research. They invented optogenetics — turning brain circuits on and off (in mice,…

Shivering is one mechanism by which heat is produced in the body. Heat production is called thermogenesis. Another mechanism is through nonshivering thermogenesis regulated by brown fat (i.e. adipose). This second type of heating mechanism kicks in when we need extra heat production such as a postnatal infant, someone developing a fever, an animal arousing…

The Bottleneck Years by H.E. Taylor Chapter 96 Table of Contents Chapter 98 Chapter 97 The Trial, March 18, 2061 Although I had resolved never to expose Edie and Anna to Jon’s vitriol since the first call, I didn’t have a lot of choice when it came to the trial. Unfortunately, I had a class…

The original tree hugger

New research sheds light why koalas (Phascolarctos cinereus) spend so much time hugging trees. As shown in the infrared image above, the trees stay cool on hot days. Since koalas do not sweat, hugging trees is another method to keep their cool in addition to panting and licking their fur. The research also shows that the…
