The test hens responded more quickly to the tidbitting males that had the normal or stationary wattles, less quickly to the one with the extra floppy wattle (….) and slowest to the male lacking wattles. After the hen’s attention was gained, though, she reacted about the same to each of the four animated chickens. Smith suggests that the wattle helps a rooster gain a hen’s attention when he is tidbitting, rather like a human guy wearing flashy clothes while doing his best dance moves to try and pick up chicks.

Some interesting work here, the full winner list is available from their website:
PEACE PRIZE
Stephan Bolliger, Steffen Ross, Lars Oesterhelweg, Michael Thali and Beat Kneubuehl of the University of Bern, Switzerland, for determining — by experiment — whether it is better to be smashed over the head with a full bottle of beer or with an empty bottle.

The directors, executives, and auditors of four Icelandic banks — Kaupthing Bank, Landsbanki, Glitnir Bank, and Central Bank of Iceland — for demonstrating that tiny banks can be rapidly transformed into huge banks, and vice versa — and for demonstrating that similar things can be done to an entire national economy.
MEDICINE PRIZE
Donald L. Unger, of Thousand Oaks, California, USA, for investigating a possible cause of arthritis of the fingers, by diligently cracking the knuckles of his left hand — but never cracking the knuckles of his right hand — every day for more than sixty (60) years.

MATHEMATICS PRIZE
Gideon Gono, governor of Zimbabwe’s Reserve Bank, for giving people a simple, everyday way to cope with a wide range of numbers — from very small to very big — by having his bank print bank notes with denominations ranging from one cent ($.01) to one hundred trillion dollars ($100,000,000,000,000).

We will all read two short articles about Cystic Fibrosis:
Each one of us will then pick one of the following topics, elaborate the discussion by reading an additional latest reference of your choice and present the major ideas in the lab meeting. (Liyun, as a physician for years, should pick up a more research-based topic).
The format will be a 10-min presentation followed by 5-min discussion. If you are discussing a research paper, the breakdown should be as follows: 5-min for background+experimental design, 5-min for 1-2 major findings. For a review paper, the breakdown should be approximately 3 mins for each major idea. The presentation should have no more than 4 slides, preferably 3, you can also use the board. We will also bring a timer.
I suggest the following six topics:
Please reply and this thread to select your topic, and upload both your presentation and the reference article to the appropriate lab meeting folder. I look forward to discussing these ideas with you!
Dr. William Mak, a good friend and a great role model, has been devoting his career to improving the biotechnology education for primary and secondary students and teachers over the years. He has established the Hong Kong Biotechnology Education Resource center with Sik Sik Yuen Ho Yu College and built a university-level research laboratory to facilitate the process. He has been working on another interesting project recently – a custom-built coach bus that serves as a mobile laboratory for the community. He made me feel proud to be a Hong Kong scientist.

Placebos Are Getting More Effective. Drugmakers Are Desperate to Know Why.

Hello everybody I’m sure you all were glued to your TV’s every night this week like I was for shark week
Ok maybe not. However, if you support the ban on shark finning to save sharks which in turn in saving the whole ocean please go to http://dsc.discovery.com/sharks/ocean-conservancy-petition.html and sign the petition. Also, for more information you can go to sharkweek.com.
We have briefly touched the subject of stem cell research in the last journal club. The challenge of developing “stem cell” as a useful therapy is three fold:
In one sense, the premise of 1 and 2 is that 3 would happen automatically once you can get the Stem cells. They are not only expected to become the desired cell type, but also are expected to know what to do inside the body. This can be a tall order.
There is actually a lot to learn from basic research to see how mother nature deals with the regeneration problem. Salamander is a great regeneration model. If you cut its limb off, the cells in the wound region will grow back a limb to its entirety.
It has long been thought that these cells that are responsible for the regeneration process are pluripotent, or “stem cell”-like. A very interesting research has proven it is otherwise. The original cells in the limb actually remember their identities, and they will only grow back to their own kind. In other words, muscle cells will become muscle cells, and skin cells will become skin cells.

It looks like that instead of having some very specialized stem cells that switch all the way back to the beginning, the differentiated cells just go back a few (?) steps and maintain their identities during the process. One wonders how this process is regulated at the network level and what has been lost in us that we do not have this capability anymore. Maybe this talent is still hibernating somewhere in our genome, waiting for us to turn it back on.
