Science is a humane conduct based on humane desire
Science is a historically evaluated system Science and technology should be under control and management of our society
Science and technology bring big changes to our society
These precious pictures may be you will be interested.
Gregor Mendel (1822ー1884）
Father (founder) of Genetics
1866 ，「Study on Plant Hybrids」
Establishment of Law of Heredity Dominance ,
A small field where Mendel grew pea plants (Pisum sativum L.) （3 x 35 m）
from left to right: P1,F1,P2
Mono-hybrid segregation; 3:1
Di-hybrid segregation; 9:3:3:1
Thomas H. Morgan （1866-1945）
Father (founder) of cytogenetics
Establishment of chromosomal basis of heredity
Morgan’s students (Morgan school) :
Alfred H. Sturtevant ,Carvin Bridges ,H. J. Muller etc.
Discovery of DNA Double helix
In front of DNA Double helix model, Cavendish laboratory, Cambridge, UK James D. Watson （２５）& Francis H. Crick （３７）
James D.Watson & Francis H. Crick
Model of DNA Double helix An original paper, 1953, April 25 Nature vol 421, p397-398
1962 Six Novel winners with diplomas Photo after ceremonies of Nobel prize Concert Hall
of Stockholm
Rosalind Franklin
Died after cancer (uterus) 1958（37）
Her famous X-ray diffraction image of DNA
Rollins Emerson’s corn school Cornell University
Teosinte, an ancestor of corn (maize) and primitive cultivars
G. W. Beadle, grinding teosinte Geroge W. Beadle （1903-1994）
“One-gene-one-enzyme” with E. L. Tatum
Barbala. McClintock：Discovery of controlling elements (transposons)
Hitoshi KIHARA: Founder of Wheat Genetics and Genomics
The History of the earth is recorded in the layers
of its crust; The history of all organisms is
inscribed in the chromosomes Kihara, 1946
15 Feb. 01
Draft sequence of the human genome
16 Feb. 01
Draft sequence of the human genome
Draft sequences of Arabidopsis (A. thaliana)
Draft sequences of rice (Oryza sativa L.) genomes
Our longevity: how long we human can live
Genetically modified corn (Star Link) carrying BT toxin gene causes allergic reactions in human?
Does BT corn destroy Environment and/or
biodiversity?
Risk and benefit prediction and management based on scientific facts are required
Genetically modified fishes (salmon, trout） with enhanced expression of growth hormone genes
Andi, a baby rhesus monkey born after genetic
modification of embryos
ANDi (integrated or Introduced DNA）
GFP（green fluorescent protein）gene of jerry
fish is integrated and expressed in Andi
Clone animals: Copy dogs after copy cats ?
Should we save endangered animals by cloning ?
Is natural enemy friendly?
Supposed to be nature- friendly natural enemy
unexpectedly destroys natural environment
Technology is not perfect Science helps improve
technology to provide better solutions
Golden Rice can save human ?
Genetically Modified Crops (GMCs) are unacceptable evil ?
Craig Venter
What is the minimum genome that can sustain life ?
Synthetic Biology:
synthesizing artificial cells (living organisms) and
utilizing them in industries bioremediation material synthesis etc.
Modification and manipulation of life artificial fertilization gene diagnosis GMOs, clones , reproductive medicine etc.
How far this goes and can be acceptable by our society ?
Scientists play god？
Life
Embryo
Cloning
ESC（embryonic stem cell）
GMO (GMC)
What is science ethics ?
What is social ethics ?
Science vs Technology
Decision is up to our society
