Beemans Gum His many contributions to biology include the development of cell theory, the discovery of Schwann cells in the peripheral nervous system, the discovery and study of pepsin, the discovery of the organic nature of yeast, and the invention of the term metabolism.

Schwann cell Supplement. Schwann cells form a fatty material called myelin to insulate the axons in the peripheral nervous system. This method decreases membrane capacitance in the axon, thus, allowing saltatory conduction. Non-myelinating Schwann cells are involved in maintenance of axons and are crucial for neuronal survival.

- Then suddenly, late in 1938, Otto Hahn (pictured at right with Lisa Meitner) and Fritz Strassmann (pictured at left) discovered a fundamentally new and unexpected exception. After irradiating uranium with neutrons, they were surprised to detect barium, an element only about half of the mass of uranium.The conclusion was inescapable; they had split the uranium atom into two parts. They had discovered nuclear fission -- the splitting of the atom.Two physical properties of nuclear fission are particularly exciting and important; splitting the uranium nucleus with a neutron releases energy and a few additional neutrons.hen suddenly, late in 1938, Otto Hahn (pictured at right with Lisa Meitner) and Fritz Strassmann (pictured at left) discovered a fundamentally new and unexpected exception.

Dinosaur Shocker Schweitzer, one of the first scientists to use the tools of modern cell biology to study dinosaurs, has upended the conventional wisdom by showing that some rock-hard fossils tens of millions of years old may have remnants of soft tissues hidden away in their interiors.

Benchmarks: Henri Becquerel discovers radioactivity on February 26, 1896 This discovery of spontaneous “radioactivity” (a term coined by Becquerel’s doctoral student, Marie Curie) eventually earned Becquerel a Nobel Prize for Physics in 1903, which he shared with Marie Curie and her husband Pierre Curie.enchmarks: Henri Becquerel discovers radioactivity on February 26, 1896.

- There are several reasons a laptop could be having trouble charging. Examine the outlet, cord, and connection first, since these are easily identified and often fixable problems. If you can't find any issues there, changing your laptop settings or resetting its battery management can sometimes solve the problem.

What Did Theodor Schwann Discover? Theordor Schwann was born in 1810. Known as a pioneer in the study of histology — the study of plant and animal tissues, Schwann largely contributed to the classification of human tissue types.

- In 1663 an English scientist, Robert Hooke, discovered cells in a piece of cork, which he examined under his primitive microscope. Actually, Hooke only observed cell walls bec … ause cork cells are dead and without cytoplasmic contents. Hooke drew the cells he saw and also coined the word CELL.lso, when Robert Hooke discovered cells, he was not a criminal and he also did not get tours of jail. He did not know what jail cells looked like. Though, he did know what semenary rooms for priests looked like, as he was very religious.

- 1 Henri Becquerel discovered the radioactive properties of uranium when he stored a piece with some film and notched an image on the film. 2  Uranium was named a radioactive element because if gives off something that is invisible to the human eye called radiation.ubsequent to Roentgen's discovery of X-rays, in 1896 a French scientist Henri Becquerel was experimenting with a uranium compound. While investigating the properties of fluorescent minerals, it was Becquerel who discovered that certain types of atoms disintegrate by themselves.

Theodor Schwann The German biologist Theodor Schwann (1810-1882) is considered a founder of the cell theory. He also discovered pepsin, the first digestive enzyme prepared from animal tissue, and experimented to disprove spontaneous generation. Theodor Schwann was born at Neuss near Düsseldorf on Dec. 7, 1810. At the University of Bonn, which he entered in 1829, he met Johannes Müller, the physiologist, whom he assisted in his experiments. Schwann continued his medical studies at the University of Würzburg and later at the University of Berlin, from which he graduated in 1834.

What Did Robert Hooke Discover? Quick Answer. In the 17th century, the English physicist Robert Hooke discovered plant cells while examining cork under a microscope. He was the first to refer to the units as cells because their boxy appearance reminded him of monastery cells. Robert Hooke, the Curator of Experiments for the Royal Society, performed extensive work with microscopes. He is also famous for discovering the law of elasticity, known as Hooke's Law, and for his book Micrographia in which he details his observations while using the microscope.

The Bessemer Process Discovered in 1855 by Sir Henry Bessemer. The Bessemer process was discovered through Sir Henry’s attempts to manufacture steel faster and more cheaply. Particularly for the purpose of manufacturing military weapons, which were at the time made with iron, which is considerably heavier than steel.

Sketching out Cell Theory, circa 1837 Soon after formulating cell theory, both Schwann and Schleiden took professorships in other cities. Their ideas continued to be refined by Müller’s students, such as Rudolf Virchow, who popularized the idea that all cells arise from cells.

- Myelinating Schwann cells begin to form the myelin sheath in mammals during fetal development and work by spiraling around the axon, sometimes with as many as 100 revolutions. A well-developed Schwann cell is shaped like a rolled-up sheet of paper, with layers of myelin in between each coil.

- Background: The Mobius Strip was discovered independently by the German mathematicians August Ferdinand Mobius and Johann Benedict Listing in 1858. It is a surface with only one side and one edge. It can be constructed by taking a strip of paper, and twisting it and connecting the ends.

Schwann cell Myelinating Schwann cells begin to form the myelin sheath in mammals during fetal development and work by spiraling around the axon, sometimes with as many as 100 revolutions. A well-developed Schwann cell is shaped like a rolled-up sheet of paper, with layers of myelin in between each coil. The inner layers of the wrapping, which are predominantly membrane material, form the myelin sheath while the outermost layer of nucleated cytoplasm forms the neurolemma.

Cell Theory Creating Cell Theory. Scientist Matthias Schleiden discovered in 1838, that all plants have cells, which are called plant cells. Theodor Schwannn found that all animals are also made up of cells, which are called animal cells. These are two types of the many different kinds of cells.
