2.7 times as wide as our home planet, with about 20 times the volume, making it a “super-Earth,” about midway in size between Earth and Neptune. As Zachory Berta, the Harvard grad student who first spotted the planet puts it: “It was difficult to understand.” Not anymore, though. A team lead by Berta has now used the Hubble Space Telescope to determine that the planet is indeed like ...
있다고 해 논란이다. How active you are on social networks such as Cyworld and Facebook may depend on the size of your brain, according to a new research. Scientists discovered that those who are more social in general tend to have larger amygdalae than their peers. Researchers found that people who have a large number of friends on Facebook tend to have more grey matter in portions of ...
and researchers say the technology could someday enable all electric vehicles to operate with one-fifth the battery size and at one-third the cost.해석 2010년 최고 과학 발명품들1위 : 신생아용 인큐베이터 '네오네처'미국의 한 대학생이 개발한 네오너처는 고물 자동차의 부품을 재활용해 사회적 필수품인 미숙아 양육 인큐베이터를 ...
agriculture does. Prof. Despommier's plans are even grander. He has drawn up models for a 30-story, city-block-size vertical farm that would have transparent walls to maximize sunlight and would produce enough food for 50,000 people.“With about 160 of these buildings, you could provide food to all of New Yorkers,”he says. But Prof. Despommier concedes that it would cost hundreds of ...
위치를 비교했다. 여기엔 한국인 표준체형을 수립하기 위해 2002년 시작된 사이즈코리아(Size Korea) 연구 결과를 사용했다.실험 결과 한국인은 비교적 앞으로 당겨 앉으며 운전자 눈 위치도 높은 것으로 나타났다. 이는 키가 같더라도 상대적으로 상체가 길고 하체가 짧은 한국인의 특징이 반영된 ...
표준인체치수 측정에는 누구나 자발적으로 참여할 수 있다. 사업단 홈페이지(www.sizekorea.or.kr)를 통해 신청하고 측정시간을 예약해 지역별 인체측정센터를 방문하면 된다. 직접측정은 3백42개 전국 시·군·구에서 이뤄지고 있다. 3차원측정은 스캐너의 수가 한정돼 있기 때문에 서울과 ...
its radius is zero. As far as we know, the electron has no structure.What is puzzling is how a particle can have no size and no structure and yet can have a definite mass and behave as though it is spinning? We do not know the answers to these questions but scientists are working on experiments to find out.The electron as a waveConfine an electron, or constrict its freedom of movement and the ...
일반적으로 증폭 DNA의 유무 및 크기, 그리고 제한효소 절편 다형현상(RFLP, restriction fragment size polymorphism) 등을 조사함으로써 수 시간내에 유전병과 관련된 대립유전자를 찾아내거나 단일 염기상에서의 돌연변이를 빠르게 찾아냄으로써 각종 유전병을 진단할 수 있으며 궁극적으로 유전자의 구조 및 ...
deep in mines. Newer projects featured tanks of gallium. One of the gallium tanks has recently been increased in size. This tank has found some low-energy electron neutrinos, but still not enough. Physicist S. Bandler at Brown University proposes a new detector made of silicon wafers plus superfluid liquid helium, to find more of the low-energy neutrinos.Another theory of neutrinos is ...
sacrificed in order to be true masters of the air. Since it wasn't possible for a flying creature to develop the brain size of a primate, the brain stayed small, but functioned more efficiently than mammalian brains. Birds have a small cerebral cortex but, per size, a bigger diencephalon (the posterior end of the forebrain). Perhaps this and their superb circulation makes their small brain ...
