Kranji extension reforestation

Went down on Sat morning to finish plotting transects for the Kranji extension reforestation project. It stormed while we were in the middle of planting the seedlings. But no lightning risk so we pushed on. I think the urgency is due to concern that the seedlings will not survive if we leave them in the pails any longer and also by the lack of time available, I still have another plot to look after, on top of my unfinished writing. Heh.

All in all 90 seedlings (mainly R. apiculata) were planted.

Hope they will all make it.

Peer reviewed open access - Public Library of Science


The doors of knowledge should not be open to the select few who know the jargon and lingo or those who can afford to hefty subscription rates. Good scientific knowledge should be shared and made available for all. In this way more people will benefit and progress will be faster.

Which was why I was so excited when I came across PLoS Biology. The collection there is pretty extensive and good. Shall share this with my students. At least now I have somewhere nice to go to once my tertiary library membership is terminated.

Sunrise at Sungei Buloh (Kranji extension)

Went back to the mangroves again for some reforestation studies. Was supposed to meet my students at 8am but I reached the place early and went for a stroll down Kranji extension instead. This beautiful sight greeted me. The sun was just creeping up silently, casting a soft warm orange glow to the surroundings. In a moment, the banks of the mangroves seem ablaze with golden light.

Was very happy I woke up early for this. Wonder how many had just slept away the hours when earth was being painted? Pity.

Set for the perfect victory


Why do I blog so much about Lance Armstrong?

He's done the impossible, surviving cancer and then gaining back his form to match a record 6 Tour de France wins and now he is on his way to his 7th. Isn't that something?

At the very last time trail, he completed the perfect picture, keeping his yellow jersey for Paris and netting a stage win at the last time trial. Now he has a very comfortable 4:40min lead over Ivan Basso of Italy, setting him up for a victory ride on the last leg into Paris on Sunday, when he will retire...

Lance is only 33. And he's retiring. But what a remarkable journey he had.

Cheers to you Lance. Allez.

Sunset on 25th Dec 2004, Ao Nang Beach, Phuket



Was arranging photos for racial harmony presentation today. The theme was based on culture, sights and sounds of tsunami struck countries. So our department set up a mini 'spa', scented candles, warm lights, soothing music and a slide show of nice pictures, the works in short.

Looking at this set of pictures always make me pause and ponder. Time can indeed dilute emotions and memories. Photos are a very good reminder of sights and sounds past. Just like the photo taken at Ao Nang beach right after we had a nice day there on Christmas day 2004. Right after a nice glass of coke and preparing for a long ride back to our hotel. Right before the earthquake of Indonesia.

Who would have thought that the beach will no longer be there the next day?

Joy

He who clings to himself a joy,
Does the winged life destroy.
But he who kisses the joy as it flies,
Lives in eternity's sunrise.

Thank you



Thank you na and ca. Thank you very much. :)

Writing for the sake of writing - Cory Doctorow

I was scanning through the Scientific Indian Blog when I came across an artwork for a bookcover which looks like Dave Mckean's. Went to the site and discovered Cory Doctorow, an science fiction author who publishes his work for free online, AND allows people from developing countries to make copies, movies, translations, plays etc from his books and charge money for them. In return he only asks that his work is not altered. Not a single cent is required.

I think this is a very generous and noble act instead. No wonder Dave Mckean did the artwork (hmm... I wonder did Dave do it for free?).

This is the link to Doctorow's site - Someone Comes To Town, Someone Leaves Town

Enjoy.

Flowering? It's all in the proteins

A novel protein FK1 was discovered by Scripps Institute. In the Science report, Steve A.Kay found that FK1 suppresses a transcriptor (CDF1) which in turn suppresses CONSTANS. CONSTANS is the protein which has been identified to trigger flowering in response to changes in day length. So when spring comes along, the plants allow FK1 to destroy more CDF1. As a consequence, the elevated levels of CONSTANS allows flowering to proceed.

This is already a very straight forward case where the trigger for flowering (change in daylength) is very obvious. Wonder what exactly goes on during mast flowering?

More details found at - Scientific American: Protein Tells Flowers When Spring Starts

Stay Hungry, Stay Foolish

I escaped the Tsunami December 2004. But I had not taken life by the reins yet.

Inertia is a sin.


Transcript of Steve Job's speech at Stanford's commencement

Thank you. I'm honored to be with you today for your commencement from one of the finest universities in the world. Truth be told, I never graduated from college and this is the closest I've ever gotten to a college graduation.

Today I want to tell you three stories from my life. That's it. No big deal. Just three stories. The first story is about connecting the dots.

I dropped out of Reed College after the first six months but then stayed around as a drop-in for another eighteen months or so before I really quit. So why did I drop out? It started before I was born. My biological mother was a young, unwed graduate student, and she decided to put me up for adoption. She felt very strongly that I should be adopted by college graduates, so everything was all set for me to be adopted at birth by a lawyer and his wife, except that when I popped out, they decided at the last minute that they really wanted a girl. So my parents, who were on a waiting list, got a call in the middle of the night asking, "We've got an unexpected baby boy. Do you want him?" They said, "Of course." My biological mother found out later that my mother had never graduated from college and that my father had never graduated from high school. She refused to sign the final adoption papers. She only relented a few months later when my parents promised that I would go to college.

This was the start in my life. And seventeen years later, I did go to college, but I na¿vely chose a college that was almost as expensive as Stanford, and all of my working-class parents' savings were being spent on my college tuition. After six months, I couldn't see the value in it. I had no idea what I wanted to do with my life, and no idea of how college was going to help me figure it out, and here I was, spending all the money my parents had saved their entire life. So I decided to drop out and trust that it would all work out OK. It was pretty scary at the time, but looking back, it was one of the best decisions I ever made. The minute I dropped out, I could stop taking the required classes that didn't interest me and begin dropping in on the ones that looked far more interesting.

It wasn't all romantic. I didn't have a dorm room, so I slept on the floor in friends' rooms. I returned Coke bottles for the five-cent deposits to buy food with, and I would walk the seven miles across town every Sunday night to get one good meal a week at the Hare Krishna temple. I loved it. And much of what I stumbled into by following my curiosity and intuition turned out to be priceless later on. Let me give you one example.

Reed College at that time offered perhaps the best calligraphy instruction in the country. Throughout the campus every poster, every label on every drawer was beautifully hand-calligraphed. Because I had dropped out and didn't have to take the normal classes, I decided to take a calligraphy class to learn how to do this. I learned about serif and sans-serif typefaces, about varying the amount of space between different letter combinations, about what makes great typography great. It was beautiful, historical, artistically subtle in a way that science can't capture, and I found it fascinating.

None of this had even a hope of any practical application in my life. But ten years later when we were designing the first Macintosh computer, it all came back to me, and we designed it all into the Mac. It was the first computer with beautiful typography. If I had never dropped in on that single course in college, the Mac would have never had multiple typefaces or proportionally spaced fonts, and since Windows just copied the Mac, it's likely that no personal computer would have them.

If I had never dropped out, I would have never dropped in on that calligraphy class and personals computers might not have the wonderful typography that they do.

Of course it was impossible to connect the dots looking forward when I was in college, but it was very, very clear looking backwards 10 years later. Again, you can't connect the dots looking forward. You can only connect them looking backwards, so you have to trust that the dots will somehow connect in your future. You have to trust in something--your gut, destiny, life, karma, whatever--because believing that the dots will connect down the road will give you the confidence to follow your heart, even when it leads you off the well- worn path, and that will make all the difference.

My second story is about love and loss. I was lucky. I found what I loved to do early in life. Woz and I started Apple in my parents' garage when I was twenty. We worked hard and in ten years, Apple had grown from just the two of us in a garage into a $2 billion company with over 4,000 employees. We'd just released our finest creation, the Macintosh, a year earlier, and I'd just turned thirty, and then I got fired. How can you get fired from a company you started? Well, as Apple grew, we hired someone who I thought was very talented to run the company with me, and for the first year or so, things went well. But then our visions of the future began to diverge, and eventually we had a falling out. When we did, our board of directors sided with him, and so at thirty, I was out, and very publicly out. What had been the focus of my entire adult life was gone, and it was devastating. I really didn't know what to do for a few months. I felt that I had let the previous generation of entrepreneurs down, that I had dropped the baton as it was being passed to me. I met with David Packard and Bob Noyce and tried to apologize for screwing up so badly. I was a very public failure and I even thought about running away from the Valley. But something slowly began to dawn on me. I still loved what I did. The turn of events at Apple had not changed that one bit. I'd been rejected but I was still in love. And so I decided to start over.

I didn't see it then, but it turned out that getting fired from Apple was the best thing that could have ever happened to me. The heaviness of being successful was replaced by the lightness of being a beginner again, less sure about everything. It freed me to enter one of the most creative periods in my life. During the next five years I started a company named NeXT, another company named Pixar and fell in love with an amazing woman who would become my wife. Pixar went on to create the world's first computer-animated feature film, "Toy Story," and is now the most successful animation studio in the world.

In a remarkable turn of events, Apple bought NeXT and I returned to Apple and the technology we developed at NeXT is at the heart of Apple's current renaissance, and Lorene and I have a wonderful family together.

I'm pretty sure none of this would have happened if I hadn't been fired from Apple. It was awful-tasting medicine but I guess the patient needed it. Sometimes life's going to hit you in the head with a brick. Don't lose faith. I'm convinced that the only thing that kept me going was that I loved what I did. You've got to find what you love, and that is as true for work as it is for your lovers. Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work, and the only way to do great work is to love what you do. If you haven't found it yet, keep looking, and don't settle. As with all matters of the heart, you'll know when you find it, and like any great relationship it just gets better and better as the years roll on. So keep looking. Don't settle.

My third story is about death. When I was 17 I read a quote that went something like "If you live each day as if it was your last, someday you'll most certainly be right." It made an impression on me, and since then, for the past 33 years, I have looked in the mirror every morning and asked myself, "If today were the last day of my life, would I want to do what I am about to do today?" And whenever the answer has been "no" for too many days in a row, I know I need to change something. Remembering that I'll be dead soon is the most important thing I've ever encountered to help me make the big choices in life, because almost everything--all external expectations, all pride, all fear of embarrassment or failure--these things just fall away in the face of death, leaving only what is truly important. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart.

About a year ago, I was diagnosed with cancer. I had a scan at 7:30 in the morning and it clearly showed a tumor on my pancreas. I didn't even know what a pancreas was. The doctors told me this was almost certainly a type of cancer that is incurable, and that I should expect to live no longer than three to six months. My doctor advised me to go home and get my affairs in order, which is doctors' code for "prepare to die." It means to try and tell your kids everything you thought you'd have the next ten years to tell them, in just a few months. It means to make sure that everything is buttoned up so that it will be as easy as possible for your family. It means to say your goodbyes.

I lived with that diagnosis all day. Later that evening I had a biopsy where they stuck an endoscope down my throat, through my stomach into my intestines, put a needle into my pancreas and got a few cells from the tumor. I was sedated but my wife, who was there, told me that when they viewed the cells under a microscope, the doctor started crying, because it turned out to be a very rare form of pancreatic cancer that is curable with surgery. I had the surgery and, thankfully, I am fine now.

This was the closest I've been to facing death, and I hope it's the closest I get for a few more decades. Having lived through it, I can now say this to you with a bit more certainty than when death was a useful but purely intellectual concept. No one wants to die, even people who want to go to Heaven don't want to die to get there, and yet, death is the destination we all share. No one has ever escaped it. And that is as it should be, because death is very likely the single best invention of life. It's life's change agent; it clears out the old to make way for the new. right now, the new is you. But someday, not too long from now, you will gradually become the old and be cleared away. Sorry to be so dramatic, but it's quite true. Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma, which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice, heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.

When I was young, there was an amazing publication called The Whole Earth Catalogue, which was one of the bibles of my generation. It was created by a fellow named Stewart Brand not far from here in Menlo Park, and he brought it to life with his poetic touch. This was in the late Sixties, before personal computers and desktop publishing, so it was all made with typewriters, scissors, and Polaroid cameras. it was sort of like Google in paperback form thirty-five years before Google came along. I was idealistic, overflowing with neat tools and great notions. Stewart and his team put out several issues of the The Whole Earth Catalogue, and then when it had run its course, they put out a final issue. It was the mid-Seventies and I was your age. On the back cover of their final issue was a photograph of an early morning country road, the kind you might find yourself hitchhiking on if you were so adventurous. Beneath were the words, "Stay hungry, stay foolish." It was their farewell message as they signed off. "Stay hungry, stay foolish." And I have always wished that for myself, and now, as you graduate to begin anew, I wish that for you. Stay hungry, stay foolish.

Thank you all, very much.

Something to smile about.

Blechnum vestitum (Parkia)


Blechnum vestitum (Parkia)
Originally uploaded by _Cheng Puay.
I think I am stressed. Which explains why I am blogging so often.

Anyway this is Blechnum vestitum or commonly known as Parkia. It was very common along the lower stretches of the climb up to Kinabalu. The young fronds are a nice red color which the locals consume as a vegetable.

Tasty when fried.

Why are the fronds red? This is a common survival strategy employed by most plants. Young leaves/ fronds are very tender and generally favored by predators. Young leaves without chlorophyll have a higher chance of higher as they resemble old leaves which are about to drop of. The herbivores are thus deceived by the color and leaves them alone.

By the time the leaves mature and has chlorophyll, it has more cellulose deposited on it and hence presents a tougher meal for any potential predator.

Another fascinating plant found in Kinabalu. The stem of the fern grows in a clockwise spiral with the fronds growing outwards like spokes of a wheel. Still trying to find its name.

Forgiveness; from a plant's perspective

Another cool botanist quote, this time by Mark Twain.

- forgiveness is the fragrance that the violet sheds on the heel that has crushed it -

Passiflora foetida



Imagine a passion fruit growing beneath our feet. This beautiful flower only blooms in the morning. By noon, the petals curl up into a white ball. Has orange fruits (diameter of a 20 cent coin) which really tastes like the big passion fruits. But reported to contain cyanide, so be careful when trying it. Dispersed by birds.

Another momentous moment in my life. Met one of my favorite authors in person, Neil Gaiman. Got 3 books signed by him, heh what more can one ask for?

Was treated to a preview of his coming movie (with the amazing Dave Mckean), Mirrormask. Amazing animation and of course great story. Hope it comes to Singapore soon.

Dillenia tree


Dillenia sp.
Originally uploaded by _Cheng Puay.
Spotted this plant in flower during my trip to west coast park yesterday. Nice white petals with a red bulls eye guiding all the pollinators to it.

Hmm... interesting mix of colors here. The white petals usually mean that the flower is insect pollinated as insects see with UV and white petals show vivid hues under UV light. But red are usually used for attracting pollinators using visible light to see.

So could this flower be a 'generalist' of sorts? Using both UV to attract insects and visible light to attract small birds (sun birds possibly)?

You can see Lekowala's nice picture of an another member of the Dillenia genus at Bend it like the Simpoh Ayer

Huge Strangling fig in Tioman

This was taken along the Tekek Juara trail. One can see the roots snaking down from the fig tree nestled amongst the branches at the top of the host tree. Perhaps in 10 years time, more roots would have descended to the ground, anchor themselves and begin to thicken. The poor host tree in the center would have no more space to grow in width. Its xylem and phloem vessels will be slowly crushed in both directions... by itself when it grows in girth and by the expanding roots engulfing it. Really amazing when one considers the original fig plant was a small seed desposited by a bird amongst the host tree's branches.
