Antibiotic

... of resistance to those drugs, and a never-ending ever-spiraling race to discover new and different antibiotics ensues, just to keep us from losing ground in the battle against infection. The fear is that we will eventually fail to keep up in this race, and the time when people did not fear ...

Antibiotic resistance

... reduce the chance of getting sick and spreading infection. Wash fruits and vegetables thoroughly. Avoid raw eggs and undercooked meat, especially in ground form. Do not demand antibiotics from your physician. When given antibiotics, take them exactly as prescribed and complete the full course of ...

Anton van Leeuwenhoek

... age because he was born in a house at the corner of Lion's Gate in Delft. Van Leeuwenhoek translates as "from lion's corner". Van Leeuwenhoek ground over 500 optical lenses during his lifetime. His microscope was used and improved by Christiaan Huygens for his own investigations into microscopy. ...

Biomechanics

... The passive mechanical response of a particular tissue can be attributed to the various proteins , such as elastin and collagen , living cells, ground substances such as proteoglycans, and the orientations of fibers within the tissue. For example, if human skin were largely composed of a protein ...

Charles Darwin

... home, he entertained his relations. His invalid aunt was being cared for by the as yet unmarried Emma , and his uncle Jos pointed out an area of ground where cinders had disappeared under loam which Jos though might have been the work of earthworms.

Molecular biology

... in evolutionary biology such as population genetics and phylogenetics . There is also a long tradition of studying biomolecules "from the ground up" in biophysics . Techniques of molecular biology Since the late 1950s and early 1960s , molecular biologists have learned to ...
