But there's something more: the Harvest Moon Festival is an important holiday in traditional Chinese communities in America. In the week preceding the festival, the death rate in the community is found to fall by 35 per cent. In the following week the death rate jumps by 35 per cent. Control groups of non-Chinese show…
the hard but just rule is that if the ideas don't work, you must throw them away. Don't waste neurons on what doesn't work. Devote those neurons to new ideas that better explain the data. The British physicist Michael Faraday warned of the powerful temptation to seek for such evidence and appearances as are in the…
...the concept of "neoteny"—the retention of juvenile features into adult life. It is a commonplace of human evolution that the transition from Australopithecus to Homo and from Homo habilis to Homo erectus and thence to Homo sapiens all involved prolonging and slowing the development of the body so that it still…
Even at its best, pre-modern medical practice did not save many. Queen Anne was the last Stuart monarch of Great Britain. In the last seventeen years of the seventeenth century, she was pregnant eighteen times. Only five children were born alive. Only one of them survived infancy. He died before reaching adulthood…
It is clear, however, that the cause of homosexuality lies in some unusual balance of hormonal influence in the womb but not later on, a fact that further supports the idea that the mentality of sexual preference is affected by prenatal sex hormones. This is not incompatible with the growing evidence that…
At school, boys are fidgety, difficult, inattentive, and slow to learn, compared to girls. Nineteen out of every twenty hyperactive children are boys. Four times as many boys as girls are dyslexic and learning disabled. "Education is almost a conspiracy against the aptitudes and inclinations of a schoolboy," wrote…
Birth after birth the line unchanging runs, And fathers live transmitted in their sons; Each passing year beholds the unvarying kinds, The same their manners, and the same their minds. Till, as erelong successive buds decay, And insect-shoals successive pass away, Increasing wants the pregnant parent vex With the fond…
Those strains that reproduce persist; those that do not reproduce die out. The ability to reproduce is what makes living things different from rocks. Besides, there is nothing inconsistent with free will or even chastity in this view of life. Human beings, I believe, thrive according to their ability to take…
Michael Ghiselin developed this idea further in 1974 and made some telling analogies with economic trends. As Ghiselin put it, "In a saturated economy, it pays to diversify." Ghiselin suggested that most creatures compete with their brothers and sisters, so if everybody is a little different from their brothers and…
The immune system consists of white blood cells that come in about 10 million different types. Each type has a protein lock on it called an "antibody," which corresponds to a key carried by a bacterium called an "antigen." If a key enters that lock, the white cell starts multiplying ferociously in order to produce an…
There are many well-established natural factors that bias the sex ratio of human offspring, proving that it is at least possible. The most famous is the returning-soldier effect. During and immediately after major wars, more sons are born than usual in the belligerent countries as if to replace the men that died…
Another insect, a scale insect, has an even more bizarre genetic parasite. When its eggs are fertilized. sometimes more than one sperm penetrates the egg. If this happens, one of the sperm fuses with the egg's nucleus in the normal way; the spare sperm hang around and begin dividing as the egg divides. When the…
Again and again in recent years evolutionary biologists have found themselves returning to the theme of parasites. As Is Richard Dawkins put it in a recent paper: "Eavesdrop [over] morning coffee at any major centre of evolutionary theory today, and you will find 'parasite' to be one of the commonest words in ti the…
Biologists have persistently overestimated the importance of physical causes of premature death rather than biological ones. In virtually any account of evolution, drought, frost, wind, or starvation looms large as the enemy of life. The great struggle, we are told, is to adapt to these conditions. Marvels of physical…
Seibel: You mention four disciplines: music, graphics, mathematics, and text those are about as old as humanity. Clearly there are powerful ideas there that are independent of computers—the computer just provides a way to explore them that might be hard without the computer. Is there also a set of interesting…
Seibel: Do you think of yourself as a scientist, an engineer, an artist, or a draftsman? Allen: I think of myself as a computer scientist I was involved in my corner of the field in helping it develop. And those were interesting times—the emergence of computer science—because there was a Ic lot of question about, "Is…
g. When Shelley pictured science as a modern Prometheus who would wake the world to a wonderful dream of Godwin, he was alas too simple. But it is as pointless to read what has happened since as a nightmare. Dream or nightmare, we have to live our experience as it is, and we have to live it awake. We live in a world…
In 1717 Lady Mary travelled to Turkey with her husband, the British Ambassador at Constantinople. There she first witnessed variolation. She described the procedure in a letter to her friend Sarah Chiswell: The small-pox, so fatal, and so general amongst us, is here entirely harmless by the invention of ingrafting…
rhe systematic development of knowledge and technology that we all 'science' originated in the millennia of prehistory, and early vomen were among these first 'scientists'. They invented tools, accumulated knowledge about edible and medicinal plants, and 3robably discovered 'the chemistry of pot-making, the physics of…
