Wisdom of the week 2011-10-23 – What you are worring about this morning is irrelevant

Steve Jobs Stanford Commencement Speech 2005

I have never got a chance to listen to this famous speech by Steve Jobs and have finally listened to it because of all the recently coverages after he has passed away. It is actually quite insightful and I would like to share with all of you.


 

I am actually quite interested in his upcoming biography, which has already triggered some interesting discussions. For example, read Steve Jobs Bio: Its 6 Most Surprising Reveals from Wired.com.

 

 

Beware of Penguin thieves!

It is fair to say that there is still so much to learn about animal behaviour. 🙂

The Nobel Prize in Physiology or Medicine 2011

The Nobel Prize in Physiology or Medicine 2011 was awarded to Bruce A. Beutler and Jules A. Hoffmann for their discoveries concerning the activation of innate immunity, and Ralph M. Steinman for his discovery of the dendritic cell and its role in adaptive immunity. A press release about the basic findings can be found here.

Dr. Fox Effect

To find out how useful the student evaluation on a lecture is, an interesting experiment was done many years ago that the researcher found an actor to deliver a lecture that he had no idea about. He only tried to make it sound impressive and confusing.  Interestingly, most students, despite being trained scientists from different fields, found that the lecture was great and they had learned from Dr. Fox. The results were so profound that they call it Dr. Fox effect now. A great coverage on this experiment can be found from weirdexperiments.com.

 


2011 Ig Nobel prize

The 2011 Ig Nobel prize ceremony just took place last night! Here is a list of the winners, a news coverage article and a youtube video of the ceremony.

 

Update: On 10/6/2011, our lab had a journal club mainly on the psychology prize, but we also talked about various interesting things related to different awards in this year.

2011 Lasker Award

This is mainly for female scientists in the lab and particularly for Chinese female scientists. This year’s Lasker Award is given to Tu Youyou, a Senior Chinese female researcher, for her discovery of artemisinin which is used to treat malaria. Artemisinin is extracted from our precious traditional chinese medicine. The Lasker Award for Basic Medical Research goes to two scientists who study chaperonins.
