아리아를 멋지게 소화한 건 사람이 아니라 한국생산기술연구원이 개발한 로봇 ‘에버(EveR)’다. 에버는 인간처럼 사고하지만 외형은 영락없는 ‘기계’인 대부분의 휴머노이드(인간형 로봇)와 달리, 피부와 얼굴까지 사람처럼 만든 안드로이드(인간처럼 생긴 로봇)다. 물론 에버가 직접 노래를 부른 ...
were significantly less likely to become infected with the virus if they took the antiretroviral drug called Truvada every day. In one study led by University of Washington researchers, which involved 4,758 heterosexual couples in which one partner was HIV positive and the other was not, transmission of the virus was reduced by 73% after three years, compared with placebo. In another study of ...
A Midwife’s Manifesta’ which was published in April 2011, Gaskin argues that America needs midwives more than ever.You started attending births with no formal medical training. How did you know you could do it?I knew how to deal with potential complica tions because kind doctors helped me.

Where Microsoft likes to enter established markets and take them over by brute force, Apple works by creating new niches and dominating them from the start. ...
Though rapid and omnipotent, human technology cannot cover the whole world of science, if our very limited perception ever can fathom. That explains why science and technology are two distinct things, though inseparable to our eyes. Therefore, the ‘separation’ mentioned in the topic did not suddenly perish in modern times; … (생략) …. ● 심사평 ●●● 신동아 학생의 ...
nursing helps prevent the adult mice from eating the young of other mothers. (It helps explain to me why we can't ever get rid of house mouse.)Through gene studies, the scientists demonstrate that nesting house mouse usually share nests with other nursing females who are close relatives. Previous research has shown that female mice do not mate with males who are closely related, so the recent ...
Poinar believes that the definition of life must be re-evaluated in the light of amber-extracted DNA. If this DNA can ever be put into a living cell, perhaps DNA itself can be called alive. He postulates that "any entity — organism, cell or molecule — capable of growth, reproduction or direct protein synthesis when placed in an optimum environment, is alive."My favorite story about amber ...
consider the amazing possibility that they are more closely related to us than a beautiful rose or a luscious apple. Several scientists at various laboratories have been experimenting and speculating that fungi have a genetic lineage that does not place them in the plant kingdom. Although fungi are organisms that seem to be plants without chlorophyll, they may have separated from Earth's ...
Perhaps comets banged into Mars, depositing water. Or maybe there's more water down under. Nobody knows for sure.So never think water in ordinary. There's always something new to be learned.모든 생명체는 물에 의지하여 살아간다. 살아있는 세포에는 수분이 제일 많으며 생존하기 위해서도 계속 수분의 공급이 필요하다.물은 무엇인가? 물은 ...
