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. Christmas days are family time. The celebration begins with supper on December 24, when the first star hits the sky. It is a symbolic reference to the Star of Bethlehem announcing the birth of Jesus. Before sitting down to the dinner, family share pieces of a wafer and everyone is wishing each other all the best for Christmas and New Year. This custom is a reference to the Last Supper and the sharing of bread. On the table should appear the traditional 12 dishes, under the table there is hay, and […]

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. A molécula HeH+ surgiu milhares de anos após o Big Bang e trata-se assim da primeira molécula de sempre a ser formada, no início do universo. A molécula, com carga positiva e conhecida como hidro-hélio, terá tido um papel determinante no começo do universo. O hidro-hélio surgiu […]

(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. At this time nobody supposed that she will become the King of Poland, as she was the third child and her father had only two thrones to be filled. 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 […]

Princess Sisi of Austria

Very popular with the Austrian people. Sisi was born on Christmas Eve in 1837 as the second daughter of Duke Maximilian and Duchess Ludovika in Bavaria, Germany. In 1853 she met her cousin Emperor Franz Joseph, who was going to marry her sister Helene. Franz Joseph of Austria fell in love with Sisi immediately and decided to marry her instead of her sister. They married, when Sisi was 16 years old. The marriage did not work out: Sisi was an independent girl and totally unprepared for the strict protocol at court, an ambitious stepmother and a busy husband who struggled to fight revolutionary and separatist tendencies in the Habsburg Empire. The court society of Vienna was making fun of her, […]

Wladyslaw III of Poland

According to a Portuguese legend, the Polish king didn’t die in Varna but he settled in Madeira. Wladyslaw Warnenczyk was King of Poland, Hungary, and Croatia until his death at the age of 20, at the Battle of Varna in 1444. He was the first-born son of Wladyslaw Jagiello who was the founder of the Jagiellonian dynasty. The battle of Varna was a decisive Ottoman victory over the crusader alliance, led by Wladyslaw Warnenczyk and John Hunyadi-voivode of Transylvania, a leading Hungarian military and political figure. The young king was killed while personally leading his own 500-strong royal Polish heavy cavalry company to directly attack the Sultan who was protected by the guard cavalry and formidable Janissary infantry. The Janissaries […]

The golden age of Poland

Zygmunt moved Poland’s capital from Cracow to Warsaw “The Golden Age of Poland” occurred during the Polish-Lithuanian Commonwealth, formally, the Crown of the Kingdom of Poland and the Grand Duchy of Lithuania, the largest and most populous countries in Europe at that time. In its largest territorial extent, the Commonwealth covered almost 1 million square km and sustained a multi-ethnic population of 11 million. Religious freedom was guaranteed by the Warsaw Confederation in 1537, which made the country one of the most tolerant. Another interesting fact is that between 1573–1795, kings to the Polish throne were selected in so-called “free elections”, disrespecting the rule of dynastic succession. The first free election took place after the last monarch of Jagiellonian dynasty died […]

Henry II of France

The twenty-fifth Capetian King of France and the son of Francis I. He is the perfect representative of the figure of a French Renaissance monarch. Indeed, under his reign (from 1547 to 1559), a lot of great writers had the opportunity to enrich the classical literature of the country. We can think for example at Montaigne, Ronsard, Du Bellay and many more. It is also at that time that the new creative and artistic movement of La Pleiade emerged. When Henry was very young, he was made the prisoner of Emperor Charles Quint, being exchanged for his father’s freedom. He is released four years later. At the age of fourteen, he is married to Catherine of Medicis with who he […]

Casimir III the Great

The King of Poland from 1333 to 1370. He was the last Polish king from the Piast dynasty, born on 30 April 1310 in Kowal, died on 5 November 1370 in Kraków. He was the youngest, third son of King Wladyslaw I (“the Elbow-high”) and Duchess Jadwiga of Kalisz. When Casimir attained the throne in 1333, his position was in danger, as his neighbors did not recognize his title. The Polish kingdom was depopulated and exhausted by the war, and the economy was ruined. Thanks to Casimir the kingdom became prosperous and wealthy, with great prospects for the future. He waged many victorious wars and doubled the size of the kingdom, mostly through the addition of lands in modern-day Ukraine. […]
