Beam me up, Scotty!

This is catch phrase from Star Trek, which sums up what the PALM Microbeam IV does to a specimen on a slide. A laser beam cuts a specimen out on a glass slide (example: the mitochondria -- that's where all the carbohydrates are "burned" when people exercise -- can be removed from a cell on a glass slide for further analysis). Then a stronger pressure exerted by the laser can lift the sample up from the slide onto the cap of a small tube, pretty much like Wiley Coyote being lifted off the air by a rocket, and then getting caught by a gigantic spider's web (pretty far-fetched, I know).

Everything is done at the microsopic level, obviously, hence another microscope is used. Yes, the lecture on microdissection was the second part of the Carl Zeiss demonstration that happened today. Dr Wolf-Dieter Schulz even demonstrated how live samples, such as worms, could be isolated from a growth medium on a Petri plate. I'm just not sure if it is intended to be beamed up onto the cap of a tube because the pressure would surely kill the worm. Material as small as chromosomes (those are the DNA strands folded up, for CSI enthusiasts) can also be isolated.

I wish technology such as this becomes more readily available for biology students in the Philippines, because during my turn in college, I only learned about microdissection through lectures, and without seeing an actual sample.

Skyflakes

-
One of the more famous Philippine exports is Skyflakes , a wheat-based, salty cracker. It is one of my emergency food items: I typically have some stocked at home and in my handbag in case I become hungry (like in traffic jams). When there's no electricity and it's impractical to cook rice (because the leftover would spoil), I'd open a pack of Skyflakes and generously coat each cracker with Cheez Whiz... if I had a bottle of it within reach. Anyway, each time I spent more than two weeks outside the Philippines, I'd be elated to see boxes of Skyflakes inside Asian stores (particularly when in I was Australia and in the USA). Back then, I took it as a sign of homesickness. When I moved to California, I didn't miss Skyflakes because Mommy made sure that there's a steady supply in the house. Skyflakes is embedded in Filipino gastronomy as a snack, a panawid-gutom , that anyone who reacts positively upon seeing Skyflakes outside the Philippines must have spe

10 things I learned while driving on Marcos Highway to Baguio City

-
I went on a day trip to the City of Pines, which was around a 700-km drive from my house. I drove  going up there and then from the city to Victoria, Tarlac. After that, my dad took over the driving duties. It was day trip with Tita Ising and Tito Sibing with us. Anyway, this trip was my first time to go to Baguio City with me behind the wheel. As everyone who drives up knows, there are three main routes to Baguio from the lowlands: Kennon Road, which ascends from Rosario, La Union. It was out of my options because it's too dangerous to use that road in the rainy season. The second route is via Naguilian Road, which makes my trip a lot longer because the beginning of the ascent is in Bauang, La Union (further north). The last route, and the one I took, was the Marcos Highway, now known as the Aspiras-Palispis Highway. This 47-km road starts from Agoo, La Union and is touted as the safest route among the three.  As I drove up and then down (on the same day; we were in Bagu

Surat Mangyan

In high school, part of the Filipino curriculum was learning about one of the country's ancient native scripts called Baybayin . I learned back then that this script was eventually abandoned because the Spanish, and eventually the Americans, encouraged the use of the Latin script for written communications. But that's in the lowlands; the rules were different up in the mountains. In the lush mountains of Mindoro, groups of indigenous people called Mangyans  live largely in isolation away from the Christianised Filipinos. This isolation has led to the continuous development of the Mangyans' old script, Surat Mangyan . As I walked inside the Ayala Museum , I saw this bamboo tube (I'm not sure if it's an instrument) with Mangyan script written all over it. I suppose that this was equivalent to a book or a song. But I haven't figured out what's written yet, despite the translation guide provided. What I can do, however, is write my name in Ma
