It is interesting that I come across this article about a robot that can conduct research and the article about the lack of jobs for scientists at the same time. A group of Japanese scientists have built a robot for conducting research experiments that may be too dangerous for human. From the cnet.com by Tim Hornyak: “Two-armed robot takes on risky lab work”
Unlike most assembly robots, its arms have seven joints, allowing it to use human tools and to perform humanlike motions easily. It automates lab work and can do tasks such as culturing more quickly and accurately than human lab techs.

As I am running a lab myself and always hope to get more data, the second I saw the setup with the pipettes, PCR and dry baths, I could not stop thinking “wouldn’t it be nice to have one of these robots to work in the lab for 24 hours…. “.
Having a good science education is essential for all of us, because that trains one’s critical thinking; while asking a lot more students to join the field is a whole different issue. A number of factors comes into play for one to decide whether he would want to pursue this career, including one’s personality, dedication, and perhaps most importantly, financial status and career aspiration. As a teacher for many students who has spent a few more years than them and has gone through some of these thinking exercises, I believe it is rather important to let students know about the reality of the career path in research rather than telling them a rosy story and blindly motivating them. To me that is just like an academic Ponzi scheme.
Here is a great article “U.S. pushes for more scientists, but the jobs aren’t there” about the situation (once again), by Brian Vastag from the Washington Post:
That reality runs counter to messages sent by President Obama and the National Science Foundation and other influential groups, who in recent years have called for U.S. universities to churn out more scientists.
What worries me the most during the counseling of younger students, is that many think they study well, can get good grades and hence going to graduate school is a natural choice. My typical response is that “you don’t want to go to graduate school”. Don’t get me wrong. I am very enthusiastic in training students and motivate them about the excitements of scientific discoveries and thinking. However, I often see students, friends and colleagues who have good heart and can study well but ended up getting frustrated about the situation when they are a bit older and have more family obligations. I often give students a few analogies to help their planning. Here is of them, compare pursuing research as a career to pursuing performing arts (or artists or TV stars, you get the idea) as a career. Don’t just look at the successful ones for inspiration and commit yourself to the path. Also look at the ones that have to struggle for survival. If you like that kind of sacrifice for you and your family and uncertainties for the career satisfaction, may be pursuing research as a career is good for you. In other words, pursuing research as a career requires not only the smartest minds, but also the strongest dedication and good financial flexibility. Unless there is a fundamental change in the system, research is not the career type that would give the stability that many may have perceived.
Since our lab is studying retina, I am intrigued in reading this article about the limitation of retina display by Apple, how we see and the future of developing better displays.
From cultofmac by John Brownlee: Why Retina Isn’t Enough
Apple’s new MacBook Pro follows the fine tradition of the iPhone 4 and third-gen iPad in that it has a super high-resolution Retina display: a 2880 x 1800 panel with an amazing 220 pixels packed in per inch.
It’s an incredible display. In fact, it’s such an incredible display that it actually has about one million, seven hundred thousand pixels more than it needs to satisfy Apple’s definition of Retina, leading some to claim that those pixels are all going to waste.
Nothing could be further from the truth.
Apple’s new MacBook Pros have absolutely great displays, but they need every single pixel they have, because the truth of the matter is that Apple’s got a long way to go before it catches its display tech up to the incredible power of human vision. And that’s a good thing, because it means we’ve got a lot to look forward to.

An interesting study have reported a way that may potential help people who suffer from spinal cord injury.
From the New York Times, “In Rat Experiment, New Hope for Spine Injuries“:
Rats with a spinal cord injury that left their hind legs completely paralyzed learned to walk again on their own after an intensive training course that included electrical stimulation of the brain and the spine, scientists reported on Thursday.

Dr. Winston Hide decides to resigns from his associate editor position of Genomics because of the expensive subscription rate of the journal precludes many in accessing important articles that are important for public health.
From The Guardian:
Today I resigned from the editorial board of a well respected journal in my field – Genomics. No longer can I work for a system that provides solid profits for the publisher while effectively denying colleagues in developing countries access to research findings.
A respectable decision! I must say that the situation in the developed countries is getting worse too. And I often have to ask my friends to download papers for me. Thus, publishing in open-access journals is a good alternative*. However, when the research budget is tight, who is going to pay for the publication fee?
