Traditions in Holland

Everybody goes out on the streets and wears orange. The traditions of Christmas Santa is not a prominent figure in the traditional Holland Christmas celebration. Instead, children look forward to the arrival of St. Nicholas in November. St. Nicholas wears red bishop’s robes and is accompanied by a helper who is known as Zwarte Piet or Black Peter.

Mecanismo para manter a pele jovem

Experiências na pele da cauda de ratinhos, que partilha muitas características com a pele humana, permitiram clarificar a competição celular na pele e identificar compostos que podem contribuir para novas soluções anti-envelhecimento. Um estudo publicado na revista Nature demonstra que a competição entre células estaminais, impulsionada por uma proteína específica de colagénio, é fundamental para manter a pele “jovem” e também para o seu envelhecimento com o tempo. O estudo, em ratinhos, identifica ainda compostos que podem contribuir para novas soluções anti-envelhecimento da pele humana. A pele envelhecida é mais fina, mais frágil e é caracterizada por uma cicatrização mais lenta das feridas, assim como reduzidos reservatórios de células específicas da pele, como os queratinócitos e melanócitos. O fenómeno da […]

Important holidays during the year

Poland is a country in which traditions and religious holidays are still very strongly cultivated. Two of the most important during the year are, of course, Christmas and Easter.

Primeira molécula de sempre

Primeira molécula de sempre formada no universo detetada pela primeira vez no espaço O hidro-hélio surgiu numa temperatura de 3.700 graus Celsius, milhares de anos após o Big Bang. É a primeira molécula de sempre formada no universo e foi detetada numa nébula a três mil anos luz. O mais antigo tipo de molécula foi detetado pela primeira vez de sempre no espaço, revelou esta quarta-feira a equipa de cientistas responsável pelo estudo.

(Micro)plásticos e poluição

A cientista britânica Imogen Napper procura origens invulgares dos plásticos nos oceanos. O seu trabalho já contribuiu para a proibição de microesferas no Reino Unido. Imogen Napper tem apenas 27 anos mas as suas investigações sobre microplásticos já fizeram a diferença. Ao mostrar que uma embalagem de um produto cosmético pode ter quase três milhões de microesferas, influenciou a proibição destas pequenas partículas de plástico no Reino Unido. Noutro estudo, mostrou que durante uma lavagem de roupa na máquina podem ser libertadas mais de 700 mil microfibras, que irão parar ao ambiente. Por detectar plástico em sítios onde não são logo visíveis, é considerada uma detective dos plásticos. A investigadora britânica cresceu em Bristol e desde a infância que frequenta […]

Algoritmos e buracos negros

A estudante de doutoramento no MIT liderou a criação de um novo algoritmo para produzir a primeira imagem de um buraco negro. Katie Bouman tem 29 anos e, até há bem pouco tempo, quase nada sabia sobre um dos enigmas “mais entusiasmantes” do universo. “Nem um só algoritmo, nem uma só pessoa fez esta imagem”, salienta a cientista. Katherine Bouman não é astrónoma. Até há seis anos, a cientista de computadores de 29 anos quase nada sabia sobre buracos negros, a não ser que eram um dos enigmas “mais entusiasmantes” do universo. Esta semana foi dado um passo gigante para os conhecer melhor. E, assim, Bouman pôde livrar-se do segredo que guardava: “É tão fantástico poder finalmente dizer ao resto […]

Jadwiga Andegaweńska

Queen or king of Poland? Actually… both. How is this possible? Just look at the story of old Polish monarch from the 14th century. Jadwiga Andegaweńska known also as Queen Jadwiga or Saint Jadwiga was a third daughter of Louis the Great, King of Hungary and Poland, and Elizabeth of Bosnia. She was born between 1373 and 1374.

However, the oldest sister died and that is why the King decided to give the throne of Poland to Jadwiga, especially when Polish people insisted to have their own King. She was crowned […]

Muco abre caminho para antibióticos

A substância viscosa protege os peixes de bactérias, fungos e vírus presentes na água. E pode ter aplicações nos humanos, revela um novo estudo. O muco que torna os peixes escorregadios pode ser fonte de novos antibióticos eficazes contra bactérias multirresistentes, como a Staphylococcus aureus, que provoca infecções graves, defendem investigadores num novo estudo. A substância viscosa protege os peixes de bactérias, fungos e vírus presentes na água aprisionando os microorganismos antes que estes consigam penetrar nos tecidos dos peixes e, de acordo com o estudo, que será apresentado na reunião anual da Sociedade Americana de Química, tem também uma composição rica em polissacarídeos (hidratos de carbono que integram estruturas orgânicas) e peptídeos (biomoléculas que agregam aminoácidos) com propriedades antibacterianas […]

Architecture: The Penguin Pool

An example of Berthold Lubetkin’s extraordinary modernist vision The penguin pool which is placed in the London Zoo is a beautiful example of Berthold Lubetkin’s extraordinary modernist vision. Completed in 1934, it encapsulated an architectural transformation that was occurring in Britain at the time. Lubetkin who was a Jewish-Georgian immigrant to London pioneered modernism in the 1930s. His work transmitted and postulated the idea that architecture was a tool of social progression. Inspired by the French architect Auguste Perret, while studying in Paris, Lubetkin encompassed and embodied ideas of re-working the neoclassical style with newer materials like concrete. His architectural style was massively popular in Britain before the war, however, afterward, his ideas were halted by staunch conservatism and a […]
