Designed Humanity? (預先設計的人類?)

Ever since medical science first started tinkering with various human parts like organs, scientists have dreamed of providing "cures" or replacement of human parts for known pathological defects by active intervention. They started off with the heart, then extended transplants to include kidneys, liver, lungs, pancreas, intestine and thymus. Having mastered various ways of combatting the difficulties of immunological rejection, they extend similar notions to tissues transplant. Nowadays, surgeons regularly perform grafting of bones, tendons" (musculo-skeletal grafts), cornea, skin, heart valves, nerves and veins etc.With the completion of the Human Genome Project "HGP" which started in 1990, scientists have been hard at work to synthesize some new and hopefully better human genome and in June 2016, they announced plans to do so under a project called "HGP-Write".

Scientists discover New Property of Photon (科學家發現新的光子特性)



Religious truths are said to be eternal. Throughout the ages, theologians and priests have repeatedly told their faithfuls what they claim to be "truths" about what this world of ours is like and when they have the needed political power, would show little restraint in using it to enforce the correctness of their views. The story of the fate of Copernicus and Galileo is now history.

What should be the proper relation between religion and science? Is the finding of science always in conflict with the dogmatic "truths" of religion? Or just sometimes eg. as when theologians eagerly adopted the "Big Bang" theory of the creation of the universe?

Icarus at the Edge of Time (伊卡洛斯在時間的邊緣)

I remember that as a child many many years ago, I read a little story in a children's monthly magazine with beautifully drawn illustrations called "Children's Paradise (兒童樂園). The moment that magazine was out in the middle of the month, I would bite my lips and use up a sizeable portion of my weekly allowance to buy a copy of it from the old lady at her tiny  news vendor stall in front of a Chinese style European restaurant at the end of the street where I used to live. I  would walk home as quickly as I could but before reaching the door of our flat, I could never resist the expectant joy of flipping over its pages rapidly to find out what kind of juicy stories there would be in that month's edition of the magazine. Once home, I would pore over its contents and devour its contents within an hour or so and then spent hours and hours admiring its fascinating drawings and had enormous fun copying some of the most beautiful pictures I found in that issue on to a paper pad (拍紙簿) with crayons or color pencils.
