Grete Kellenberger-Gujer
Grete Kellenberger-Gujer (1919–2011) was a Swiss molecular biologist known for her discoveries on genetic recombination and restriction modification system of DNA. She was a pioneer in the genetic analysis of bacteriophages and contributed to the early development of molecular biology. Biography After earning her ''matura'' in classics at the Töchterschule in Zürich, Grete Gujer studied chemistry at the Swiss Federal Institute of Technology in Zurich. There, she met Eduard Kellenberger, a physics student. The couple married in 1945. In 1946 they moved to Geneva, where Eduard Kellenberger began his doctoral work thesis under the supervision of Jean Weigle, professor of physics at the University of Geneva. Grete Kellenberger contributed to the development of new methods to prepare and analyse biological samples using an electron microscope, a new technique at the time. After Jean Weigle left for the California Institute of Technology in 1948, Grete Kellenberger took on an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electron Microscope
An electron microscope is a microscope that uses a beam of accelerated electrons as a source of illumination. As the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons, electron microscopes have a higher resolving power than light microscopes and can reveal the structure of smaller objects. A scanning transmission electron microscope has achieved better than 50 pm resolution in annular dark-field imaging mode and magnifications of up to about 10,000,000× whereas most light microscopes are limited by diffraction to about 200 nm resolution and useful magnifications below 2000×. Electron microscopes use shaped magnetic fields to form electron optical lens systems that are analogous to the glass lenses of an optical light microscope. Electron microscopes are used to investigate the ultrastructure of a wide range of biological and inorganic specimens including microorganisms, cells, large molecules, biopsy samples, ...

Molecular Biologists
Molecular biology is the branch of biology that seeks to understand the molecular basis of biological activity in and between cells, including biomolecular synthesis, modification, mechanisms, and interactions. The study of chemical and physical structure of biological macromolecules is known as molecular biology. Molecular biology was first described as an approach focused on the underpinnings of biological phenomena - uncovering the structures of biological molecules as well as their interactions, and how these interactions explain observations of classical biology. In 1945 the term molecular biology was used by physicist William Astbury. In 1953 Francis Crick, James Watson, Rosalind Franklin, and colleagues, working at Medical Research Council unit, Cavendish laboratory, Cambridge (now the MRC Laboratory of Molecular Biology), made a double helix model of DNA which changed the entire research scenario. They proposed the DNA structure based on previous research done by Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sabbatical
A sabbatical (from the Hebrew: (i.e., Sabbath); in Latin ; Greek: ) is a rest or break from work. The concept of the sabbatical is based on the Biblical practice of ''shmita'' (sabbatical year), which is related to agriculture. According to , Jews in the Land of Israel must take a year-long break from working the fields every seven years. Starting with Harvard University in 1880, many universities and other institutional employers of scientists, physicians, and academics offer the opportunity to qualify for paid sabbatical as an employee benefit, called ''sabbatical leave''. Early academic sabbatical policies were designed to aid their faculty in resting and recovering, but were also provided in order to facilitate "advancements in knowledge in vogue elsewhere...an intellectual and practical necessity" for both the professors and university education more broadly. Present day academic sabbaticals typically excuse the grantee from day to day teaching and departmental duties, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manhattan, Kansas
Manhattan is a city and county seat of Riley County, Kansas, United States, although the city extends into Pottawatomie County. It is located in northeastern Kansas at the junction of the Kansas River and Big Blue River. As of the 2020 census, the population of the city was 54,100. The city was founded by settlers from the New England Emigrant Aid Company as a Free-State town in the 1850s, during the Bleeding Kansas era. Nicknamed "The Little Apple" as a play on New York City's "Big Apple", Manhattan is the home of Kansas State University and has a distinct college town atmosphere. History Native American settlement Before settlement by European-Americans in the 1850s, the land around Manhattan was home to Native American tribes. From 1780 to 1830, it was home to the Kaw people, also known as the Kansa. The Kaw settlement was called Blue Earth Village (Manyinkatuhuudje), named after the river which the tribe had named the Great Blue Earth River, today known as t ...
