Krefeld
Krefeld ( , ; li, Krieëvel ), also spelled Crefeld until 1925 (though the spelling was still being used in British papers throughout the Second World War), is a city in North Rhine-Westphalia, Germany. It is located northwest of Düsseldorf, its center lying just a few kilometers to the west of the river Rhine; the borough of Uerdingen is situated directly on the Rhine. Because of its economic past, Krefeld is often referred to as the "Velvet and Silk City". It is accessed by the autobahns A57 (Cologne– Nijmegen) and A44 (Aachen–Düsseldorf– Dortmund–Kassel). Krefeld's residents now speak ', or standard German, but the native dialect is a Low Franconian variety, sometimes locally called ', ', ', or sometimes simply '. The Uerdingen line isogloss, separating general dialectical areas in Germany and neighboring Germanic-speaking countries, runs through and is named after Krefeld's Uerdingen district, originally an independent municipality.

Photocurrent
Photocurrent is the electric current through a photosensitive device, such as a photodiode, as the result of exposure to radiant power. The photocurrent may occur as a result of the photoelectric, photoemissive, or photovoltaic effect. The photocurrent may be enhanced by internal gain caused by interaction among ions and photons under the influence of applied fields, such as occurs in an avalanche photodiode (APD). When a suitable radiation is used, the photoelectric current is directly proportional to intensity of radiation and increases with the increase in accelerating potential till the stage is reached when photo-current becomes maximum and does not increase with further increase in accelerating potential. The highest (maximum) value of the photo-current is called saturation current. The value of retarding potential at which photo-current becomes zero is called cut-off voltage or stopping potential for the given frequency of the incident ray. Photovoltaics The generation ...

Rumford Prize
Founded in 1796, the Rumford Prize, awarded by the American Academy of Arts and Sciences, is one of the oldest scientific prizes in the United States. The prize recognizes contributions by scientists to the fields of heat and light. These terms are widely interpreted; awards range from discoveries in thermodynamics to improvements in the construction of steam boilers. The award was created through the endowment of US$5,000 to the Academy by Benjamin Thompson, who held the title "Count Rumford of the United Kingdom," in 1796. The terms state that the award be given to "authors of discoverie's in any part of the Continent of America, or in any of the American islands." Although it was founded in 1796, the first prize was not given until 1839, as the academy could not find anyone who, in their judgement, deserved the award. The academy found the terms of the prize to be too restrictive, and in 1832 the Supreme Court of Massachusetts allowed the Academy to change some of the provisi ...

Gero Miesenböck
Gero Andreas Miesenböck (born 15 July 1965) is an Austrian scientist. He is currently Waynflete Professor of Physiology and Director of the Centre for Neural Circuits and Behaviour (CNCB) at the University of Oxford and a fellow of Magdalen College, Oxford. Education and early life A native of Austria, Miesenböck was educated at the University of Innsbruck and Umeå University in Sweden. He graduated sub auspiciis praesidentis rei publicae from the University of Innsbruck Medical School. Following his Doctor of Medicine (MD) in 1993, he undertook postdoctoral training with James Rothman. Research and career Miesenböck is known as the founder of optogenetics. He was the first scientist to modify nerve cells genetically so that their electrical activity could be controlled with light. This involved inserting DNA for light-responsive opsin proteins into the cells. Miesenböck used similar genetic modifications to breed animals whose brains contained light-responsive ne ...

The Brain Prize
The Brain Prize, formerly known as The Grete Lundbeck European Brain Research Prize, is an international scientific award honouring "one or more scientists who have distinguished themselves by an outstanding contribution to neuroscience and who are still active in research". Founded in 2011 by thLundbeck Foundation the prize is associated with a DKK 10 million award to the nominees, the world’s largest brain research prize. Nominees can be of any nationality. Prize winners are expected to interact with Danish brain researchers e.g. through lectures, master classes, seminars, exchange programmes for researchers or other activities agreed with and financially supported by the Lundbeck Foundation. History The Brain Prize was established by the Lundbeck Foundation in 2010 as a European prize and was awarded for the first time in 2011. Today the Prize is global. Selection committee As of 2019, the selection committee for the prize consisted of: * Richard G. Morris (chair) * Story Lan ...

Academy Of Sciences Leopoldina
The German National Academy of Sciences Leopoldina (german: Deutsche Akademie der Naturforscher Leopoldina – Nationale Akademie der Wissenschaften), short Leopoldina, is the national academy of Germany, and is located in Halle (Saale). Founded on January 1, 1652, based on academic models in Italy, it was originally named the ''Academia Naturae Curiosorum'' until 1687 when Emperor Leopold I raised it to an academy and named it after himself. It was since known under the German name ''Deutsche Akademie der Naturforscher Leopoldina'' until 2007, when it was declared to be Germany's National Academy of Sciences. History ' The Leopoldina was founded in the imperial city of Schweinfurt on 1 January 1652 under the Latin name sometimes translated into English as "Academy of the Curious as to Nature." It was founded by four local physicians- Johann Laurentius Bausch, the first president of the society, Johann Michael Fehr, Georg Balthasar Metzger, and Georg Balthasar Wohlfarth; and ...

Optogenetics
Optogenetics is a biological technique to control the activity of neurons or other cell types with light. This is achieved by expression of light-sensitive ion channels, pumps or enzymes specifically in the target cells. On the level of individual cells, light-activated enzymes and transcription factors allow precise control of biochemical signaling pathways. In systems neuroscience, the ability to control the activity of a genetically defined set of neurons has been used to understand their contribution to decision making, learning, fear memory, mating, addiction, feeding, and locomotion. In a first medical application of optogenetic technology, vision was partially restored in a blind patient. Optogenetic techniques have also been introduced to map the functional connectivity of the brain''.'' By altering the activity of genetically labelled neurons with light and using imaging and electrophysiology techniques to record the activity of other cells, researchers can identify ...

Light-gated Ion Channel
Light-gated ion channels are a family of ion channels regulated by electromagnetic radiation. Other gating mechanisms for ion channels include voltage-gated ion channels, ligand-gated ion channels, mechanosensitive ion channels, and temperature-gated ion channels. Most light-gated ion channels have been synthesized in the laboratory for study, although two naturally occurring examples, channelrhodopsin and anion-conducting channelrhodopsin, are currently known. Photoreceptor proteins, which act in a similar manner to light-gated ion channels, are generally classified instead as G protein-coupled receptors. Mechanism Light-gated ion channels function in a similar manner to other gated ion channels. Such transmembrane proteins form pores through lipid bilayers to facilitate the passage of ions. These ions move from one side of the membrane to another under the influence of an electrochemical gradient. When exposed to a stimulus, a conformational change occurs in the transmembrane ...
