aAs the problem became more serious,scientists began searching for a way to deal with it.They discovered a natural pollution control system for building-green plants. 当问题变得更加严肃,科学家开始搜寻方式应付它。他们发现了一个自然污染控制系统为大厦绿色植物。[translate] ...
Using an approach called DNA origami, scientists at Caltech have developed a technique that could lead to cheaper, reusable biomarker sensors for quickly detecting proteins in bodily fluids, eliminating the need to send samples out to lab centers for testing. A coarse-grained model of the DNA or...
Where did Dalton discover the atomic theory? What did Marie Curie discover about the atom? What type of scientist was Ernest Rutherford? Who discovered the electron? What subatomic particle did the cathode ray tube discover? Did John Dalton discover the atom? What scientists contributed to the at...

What scientists refer to as the first "ice-free" Arctic summer year will occur when the Arctic has less than 1 million square kilometers of sea ice. The thick ice sheets surrounding Canada's Arctic islands are likely to remain for much longer, even in summer. As the climate changes, the...
the electrons that ultimately pair to form the superconducting state behave differently than those in the cuprates. More specifically, while the electrons in the cuprates are strongly correlated - meaning the energy of one electron is tied to the energy of the others - the electrons in the ...
The nuclear age in which the human race is living,and may soon be dying,began for the general public with the dropping of an atom bomb on Hiroshima on 6 August 1945.But for nuclear scientists and for certain American authorities,it had been known for some time that such a weapon was ...
and some were just built different. One of the smallest specimens that has been discovered is the Trilophosuchus, which lived in Australia around 13 million years ago. Only part of its skull was found, but when scientists extrapolated its size, they estimated it measured less than 3 feet an...
Scientists study the cell's structure, atoms, molecules, and elements in understanding physical substances and environments. For example, scientists study how bacteria grow in warm environments, how cells are formed or how viruses attach...
