Olga Kennard
Olga Kennard, Lady Burgen ( Weisz; 23 March 1924 – 1 March 2023) was a Hungarian-born British scientist who specialised in crystallography. She was the founder of the Cambridge Crystallographic Data Centre. Kennard's research focused on determining the structures of organic molecules, including the first three-dimensional structure of adenosine triphosphate and particularly the different forms of DNA. Together with JD Bernal she believed in the value of collating scientific data in a central archive, this began the Cambridge Structural Database (CSD), collating crystal structures of mainly organic molecules. Kennard was also involved, at CSD, in the founding of the Protein Data Bank, and of the EMBL nucleotide sequence data library (later, European Nucleotide Archive). Early life and education Kennard was born in Budapest, Hungary on 23 March 1924, to Joir and Catherina Weisz. She moved to the United Kingdom at the age of 15 with her family in the face of growing antisemit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Officer Of The Order Of The British Empire
The Most Excellent Order of the British Empire is a British order of chivalry, rewarding valuable service in a wide range of useful activities. It comprises five classes of awards across both civil and military divisions, the most senior two of which make the recipient either a Orders, decorations, and medals of the United Kingdom#Modern honours, knight if male or a dame (title), dame if female. There is also the related British Empire Medal, whose recipients are affiliated with the order, but are not members of it. The order was established on 4 June 1917 by King George V, who created the order to recognise 'such persons, male or female, as may have rendered or shall hereafter render important services to Our Empire'. Equal recognition was to be given for services rendered in the UK and overseas. Today, the majority of recipients are UK citizens, though a number of Commonwealth realms outside the UK continue to make appointments to the order. Honorary awards may be made to cit ...

The Guardian
''The Guardian'' is a British daily newspaper. It was founded in Manchester in 1821 as ''The Manchester Guardian'' and changed its name in 1959, followed by a move to London. Along with its sister paper, ''The Guardian Weekly'', ''The Guardian'' is part of the Guardian Media Group, owned by the Scott Trust Limited. The trust was created in 1936 to "secure the financial and editorial independence of ''The Guardian'' in perpetuity and to safeguard the journalistic freedom and liberal values of ''The Guardian'' free from commercial or political interference". The trust was converted into a limited company in 2008, with a constitution written so as to maintain for ''The Guardian'' the same protections as were built into the structure of the Scott Trust by its creators. Profits are reinvested in its journalism rather than distributed to owners or shareholders. It is considered a newspaper of record in the UK.

National Institute For Medical Research
The National Institute for Medical Research (NIMR), was a medical research institute based in Mill Hill, on the outskirts of north London, England. It was funded by the Medical Research Council (MRC); In 2016, the NIMR became part of the new Francis Crick Institute, which was constructed next to St Pancras railway station in the Camden area of central London. History Foundation The Medical Research Council, founded in 1913, was immediately charged with establishing a central research institute in London. Later that year, premises at Hampstead were acquired and the National Institute for Medical Research was founded. However, the outbreak of World War I soon afterwards delayed occupation of the building, although senior staff were appointed and began work. By 1920 the institute at Mount Vernon Hospital was fully operational and remained so for 30 years until the move to Mill Hill. The original institute, under the directorship of Sir Henry Dale, had three divisions: * Bact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vitamin A
Vitamin A is a fat-soluble vitamin that is an essential nutrient. The term "vitamin A" encompasses a group of chemically related organic compounds that includes retinol, retinyl esters, and several provitamin (precursor) carotenoids, most notably Β-Carotene, β-carotene (''beta''-carotene). Vitamin A has multiple functions: growth during embryo development, maintaining the immune system, and healthy vision. For aiding vision specifically, it combines with the protein opsin to form rhodopsin, the light-absorbing molecule necessary for both low-light (scotopic vision) and color vision. Vitamin A occurs as two principal forms in foods: A) retinoids, found in Animal source foods, animal-sourced foods, either as retinol or bound to a fatty acid to become a retinyl ester, and B) the carotenoids Α-Carotene, α-carotene (''alpha''-carotene), β-carotene, Γ-Carotene, γ-carotene (''gamma''-carotene), and the xanthophyll beta-cryptoxanthin (all of which contain β-ionone rings) that ...

Rhodopsin
Rhodopsin, also known as visual purple, is a protein encoded by the ''RHO'' gene and a G-protein-coupled receptor (GPCR). It is a light-sensitive receptor protein that triggers visual phototransduction in rod cells. Rhodopsin mediates dim light vision and thus is extremely sensitive to light. When rhodopsin is exposed to light, it immediately photobleaches. In humans, it is fully regenerated in about 30 minutes, after which the rods are more sensitive. Defects in the rhodopsin gene cause eye diseases such as retinitis pigmentosa and congenital stationary night blindness. History Rhodopsin was discovered by Franz Christian Boll in 1876. The name rhodopsin derives from Ancient Greek () for "rose", due to its pinkish color, and () for "sight". It was coined in 1878 by the German physiologist Wilhelm Friedrich Kühne (1837–1900). When George Wald discovered that rhodopsin is a holoprotein, consisting of retinal and an apoprotein, he called it opsin, which tod ...
