ruled Earth. Or the variation in primates, even in hominids, over our relatively few millennia on Earth.But one more word on amber and DNA. Synthetic amber is now made. DNA can be extracted from human cells. The next best-seller will probably be about putting that DNA into synthetic amber so that future generations can recreate the forms of their ancestors — or maybe just wear the ancestral ...
Friendly FungiFungi are in the news, and favorably for a change. The trouble is that "fungus" is not a beautiful word, and is the name for an organism most people do not applaud, unless it happens to be one of the edible kinds.We eat fungi in mamy forms, from the multicellular mushroom to the unicellular yeast that makes our bread rise and our beverages ferment. Otherwise we tend to regard ...
take cod liver oil than to risk skin cancer, especially with the hole in the protective ozone layer growing.The latest word on skin cancer comes from Australia. It seems that dogs, cats, even cattle and pigs can also get skin cancer, especially if they are light-colored. Native Australian animals have skin pigment that protects against the sun, but the pets(from European stock) do not, and are ...
들어간다.만약 환자의 신장에 이상이 있어 보이면 그 자리에서 '신장병'이라는 키워드(key word)를 눌러 신장질환과 관련된 각종 정보를 얻는다. 또한 환자의 병력을 기록해놓은 자료도 막바로 불러낼 수 있고, 약의 처방시에도 데이터베이스에 저장해 둔 처방지침을 끄집어 내 참조할 수 있다.피시맨의 ...
Then there was a day for "software"(the computer instructions that make hardware do the work you want it to do, like a word processing program).Most amazing, the conference also had a day for "wetware," the synthetic replicating molecules nurtured by the likes of Dr. Rebek. There was even an artificial life "4-H Show" (as in rural livestock exhibits), during which scientists showed their ...
York's Staten Island. It's ironic that "Kills" means death-dealing in English but in this case comes from the Dutch word for channel. Some day the city barges will be turned away from Staten Island, unless we really want another Mount Everest looming beside the Verrazano narrows.Landfills are problematical. They aren't decomposing into nice soil overnight. Many plastics and metals stay put ...
as old as the galaxy-6 billion years-and unlike open clusters were relatively stable.Scientists are now rethinking the word "stable." The large globular cluster 47 Tucanae appears to be producing two rare kinds of stars. One is the "blue straggler," a star that seems to have been given an extra amount of lifetime. The other is the "millisecond pulsar," formed when ordinary stars use up their ...
made by a play called "R. U. R." (Rossum's Universal Robots), by Czech playwright Karel Capek. Since then the Czech word "robot," meaning "serf," has been used to describe a manufactured device able to do the work of human beings. In fiction, a robot usually looks humanoid, but the name has come to apply to many devices that perform the actions of some human parts, like an automated factory's ...
define noise as harsh loud, discordant sound. Although noise is more complicated than that "discordant" is a good word, for that's what scientists mean when they say noise is a random and therefore unpredictable signal.Noise pollution is ordinarily man-made and can literally endanger us. Stand near an airplane taking off, or a jackhammer tearing up the streeL or a superamplised rock band. Do ...
fact is, protein is a remarkable word and an even more remarkable part of the universe. "Protein" comes from a Greek word meaning "of first importance" - and so it is, for without proteins, there would no life.Protein was the name suggested by that inveterate namer of organic compounds, the Swedish chemist Jons Jakob Berzelius. The Dutch chemist Geratdus Johannes Mulder used Berzelius' ...
