Courses taken for this spring semester

I've been taking 2 (BISC395 & BICH602O) and auditing 1 courses (CENG364) for this semester. BISC395 and BICH602O are just the courses for fulfilling the credit requirement of my study program. I audit the course CENG364 - Biomolecular Engineering opened by the Chemical Engineering Department, because I want to explore more about the engineering principles in biological science for my present research, as well as my future career (maybe as a synthetic biologist devoted my study to the 2nd generation of biofuels).


Courses' descriptions:

Yes Man

Tonight, I watched a funny movie with a positive message implanted - Yes Man, which was starred by Jim Carrey (one of my favorite actors).



Say "Yes" to life!

My 2nd PG seminar

I feel good, 'cause I've just finished my 2nd PG seminar today. I went crazy last week. I did experiments and stayed in lab until 4-5 am for most of the weekdays, in a hurry to come up with some important data for my annual presentation. It's really harsh. But the good thing was that I did get some satisfactory results.

Two Biology 101 questions


True / False




Question 1:
Are elaborate peacock feathers designed to attract the opposite sex?




Question 2:
Do chameleons change color (as camouflage) to hide from their predators, e.g. birds?




Biology textbooks from high schools and universities tell us that the answers should be both true, however scientific studies from the last year suggested a different idea. Just check out the references below for the explanations.

Save the world!

I've been thinking for a long time to watch the documentary - An Inconvenient Truth. Today, I bought the DVD and checked it out. The former US Vice President Al Gore, who also won the Nobel Peace Prize in 2007, delivers a message that global warming is a real and present danger in the documentary film. We realize it with feelings now! We need to wake up, and do something about it now for the sake of mankind. Check out the following link and take some actions: http://www.climatecrisis.net/takeaction/


Melissa Etheridge - I Need to Wake Up [Nobel Prize Concert (live)]



Have I been sleeping?
I’ve been so still
Afraid of crumbling
Have I been careless?
Dismissing all the distant rumblings
Take me where I am supposed to be
To comprehend the things that I can’t see

'Cause I need to move
I need to wake up
I need to change
I need to shake up
I need to speak out
Something’s got to break up
I’ve been asleep
And I need to wake up
Now

And as a child
I danced like it was 1999
My dreams were wild
The promise of this new world
Would be mine
Now I am throwing off the carelessness of youth
To listen to an inconvenient truth

That I need to move
I need to wake up
I need to change
I need to shake up
I need to speak out
Something’s got to break up
I’ve been asleep
And I need to wake up
Now

I am not an island
I am not alone
I am my intentions
Trapped here in this flesh and bone

Oh I need to move
I need to wake up
I need to change
I need to shake up
I need to speak out
Something’s got to break up
I’ve been asleep
And I need to wake up
Now

I want to change
I need to shake up
I need to speak out
Oh, Something’s got to break up
I’ve been asleep
And I need to wake up
Now

Erasable memories?!

Researchers at SUNY Downstate Medical Center have found that a molecule known to preserve memories – PKMzeta – specifically stores complex, high-quality memories that provide detailed information about an animal’s location, fears, and actions, but does not control the ability to process or express this information. “If further work confirms this view we can expect to one day see therapies based on PKMzeta memory erasure,” Dr. Fenton suggested (a professor of physiology and pharmacology and of neurology, at SUNY Downstate). “Negative memory erasing not only could help people forget painful experiences, but might be useful in treating depression, general anxiety, phobias, post-traumatic stress, and addictions,” he added.

Wow! I don't research on neural science and know only a little about it. The discovery indeed surprised and excited me. Imagining one day we could treat our brain like a hard disk of a computer, the memories could be added and erased from it. The debilitating and sad memories could be removed, while the happy memories could be replayed and replayed again by inserting specific memory molecules (PKMzeta + others) containing them. Also, your experiences could be shared with others by sharing your memory molecules - experiencing what you/others feel in a high-definition manner. Moreover, the future film industry might convert the information of a film into particular memory molecules, so that we can experience everything "for real". Furthermore, it reminded me of the movie - The Matrix. In this movie, things like martial arts, knowledge..., etc, can be learnt instantly by charging the brain. By adding and modifying memory molecules might be analogs to it in a far future! Then, it doesn't take a long time to produce a PhD, and time can be saved to do many other stuff. Good news to many students!

If these happened, there might be a privacy problem, such as one might spy on you by using this technology. Terrorism problem too - one might copy his/her buggy idea into other people to initiate a mass attack or something else (sort of a mind-control problem). Maybe, I imagined too much, and just stop here. Anyway, this is an exciting discovery.

The spirit of Christmas

Blog 'miracle' saves Christmas for hard-luck family

(CNN) -- A family facing foreclosure is anything but a unique story in these troubled economic times.

But this is a happier story of one family whose financial ruin was averted by the actions of a friend, the compassion of strangers, the networking power of the Internet and the holiday spirit of giving.

"This is our Christmas story," said Ebony Sampson. "It's going to be told for generations and generations to come."

Sampson, who lives in Aberdeen, Maryland, with her husband, Daniel, and their two young children, has overcome more hardship than one person should ever have to face. When she was in the 10th grade, she lost her entire family in a horrific car accident. Raised by a grandmother in New York, Ebony eventually used some life-insurance money from her parents' death to buy the home in Aberdeen, near where she grew up.

But in June, Daniel got sick. After several tests, his doctors concluded that he was suffering from salmonella after eating a tainted tomato. As a new employee of Bank of America, he had not accrued enough paid time off to keep his job as a credit-card account manager.

Suddenly, the sole breadwinner in the Sampson household was out of work. Though the Sampsons received unemployment checks from the government, the money wasn't enough to make ends meet.

First came the shut-off notices from the electric company. Then one of their cars broke down. One morning, Daniel woke up and looked out his bedroom window and saw his truck was missing. It had been repossessed.

With no job, no car and no income, the Sampsons got another surprise: Ebony Sampson learned she was eight weeks pregnant.

The Sampsons returned home from church, where they are practicing ministers, on a Sunday in November to find a stranger knocking on their front door. He wanted to put a bid in on their house. Ebony told him their home was not for sale. The next day, the Sampsons were notified that they were facing foreclosure unless they could come up with $10,000 in the next two weeks to bring their mortgage up to date.

"Once we received that letter, it was like, 'Oh my God, what are we going to do?' " Daniel Sampson said. "I don't think anyone in their right mind would receive a foreclosure notice and not be rattled by it."

Somehow, the couple maintained their sense of humor. Ebony Sampson called one of her oldest friends, Jaki Grier, and jokingly asked her if she had $10,000. Jaki told her, "Sure, just let me open up my invisible purse!"

But then Grier got an idea.

A self-described geek, Grier started blogging years ago. Since then, she's contributed to a magazine's Web site and regularly posts thoughts and life happenings on her LiveJournal page. So, she published Ebony and Daniel's story, along with a link where people could make a donation.

At the most, Jaki thought she could raise enough money to help the Sampsons pay a security deposit on an apartment after their home was auctioned.

But donations started pouring in. Within 24 hours, Grier's blog had raised $1,000, far exceeding her expectations. People started linking to Grier's blog from sites across the Internet and around the country.

Attorneys posted legal advice. Others in similar situations offered sympathy. One woman sent a donation with a note that said she had just lost her own home but wanted to help anyway. Another woman wrote that she didn't have a car but would walk to her grocery store with a jar of change and donate it to the cause.

Yet another e-mail came from a woman who was unemployed, with no job prospects. She donated a dollar.

With every donation, the total raised ticked higher and higher on Grier's blog.

"Everybody wants to give to a charity, but so many times when you give to a charity you don't really see where your money goes," Grier said. "At least with this, you saw the little [donations] ticker go. I think that made people excited."

Four days after Grier's blog post, she had raised $3,400 -- enough to repair the Sampsons' car. That night, Grier went to bed ecstatic. The next morning she checked her PayPal account and was stunned to find the balance had ballooned to $10,900.

In the time it took Grier to take the donation link down from her blog, the balance had reached $11,032. In just five days, she had raised enough money to save her friend's home. A Baltimore TV station, WBAL, caught wind of the story and put it on the air. Someone contacted Daniel Sampson and offered him a job interview.

"It's been overwhelming," Daniel Sampson said. "For me, out of all the donations [we] received, it was a little kid [who] came knocking on the door early Saturday morning ... with a five-dollar bill in his hand. He just came up to the door and said, 'Here you go, mister.' Then he just walked away. I was, like, speechless. He couldn't have been more than 8 years old."

Now Daniel and Ebony Sampson will be able to enjoy Christmas much more than they thought they would just a few weeks ago. They say that once their children are grown, they'll tell them the story of how one holiday season they came within days of losing their house. They'll spend this Christmas full of thanks.

"It doesn't seem real to me, and so I just thank everyone out there that cares," Ebony Sampson said. "There really was no hope for us. Then, out of nowhere, just the kindness of strangers, just people that came and, you know, provided for us. Jaki was our beacon of light that led them to us.

"It's a personal blessing. It's a personal miracle. It makes you understand what the season is all about."
