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 […]

Traditions in my country

The traditions in Liechtenstein are very similar to the rest of Europe. Our Christmas traditions start on the first Sunday of December.

(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 […]

Celebrations

How to celebrate Carnival, Easter or Christmas in Germany. In Germany, the carnival season starts already at the 11th of November and ends months later at Ash Wednesday, which means that our season is much longer than in most of the other countries. However, there is a lot to experience during this time and most of the people are crazy about this season of the year. On the 11th of November, different villages and cities present their carnival prince of the season and celebrate the beginning of carnival with performances and music. From the beginning of January, you can visit lots of different carnival events, where dancing groups or well-known carnival bands perform traditional carnival dances and carnival-live-music. Everyone is […]

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, […]

Unknown Similarities

Unknown similarities found even in distant and most different places. How to compare two places that appear to be so completely different at first glance? Funchal, the thriving southern metropolis and my small home village Husen, a part of western Germany, totally unknown to 99% of the world’s population. My village consists of round about 1,000 people, a stark contrast to the population of Funchal with its over 110,000 inhabitants. And even if we take a look at the two cities my village belongs to, Lichtenau and Paderborn, there do not seem to be that many similarities. The most obvious connection might be the big Portuguese community in Paderborn, which offers Fado concerts, as well as Portuguese language and cooking […]

Differences: Kajaani and Funchal

There is still one significant similarity. European Union. Today’s temperature in Funchal is 25 degrees. In my home city, Kajaani, it is 5 degrees. Here in Funchal, we have palm trees, sand, flowers, and an ocean. In Kajaani, we have grass, birch trees, and lakes. By night streets of Funchal are full of people. By night in Kajaani, there are no people on the streets, and actually not necessarily in days. My name is Anni Ruskela and I am from Kajaani, Finland. Currently, I live here in Funchal, Madeira. I am going to stay here for seven months. It already feels like I have been here many months. Funchal is already my second home; all these streets that I am […]

Embracing a city

When I think about Amsterdam, I think about the sensory experiences of the city. The sound of tourists’ suitcases rolling over cobblestones, the penetrating smell when you pass a coffee shop in one of the alleyways or the rain on your skin when you’re cycling to the other side of town. I think about crowded cafes when our football team plays. How whole streets turn orange, our national color, and the excitement on people’s faces. How people cheer when our team scores and how the cafes turn to silent mumbling and cursing when the other team scores. How you can’t get out of these places without having had a beer shower or being hugged by random strangers when the orange […]

A small Dutch village

Smell the freshly cut grass, look at the swallows and make a trip on the tractor. Kolderveen is an extremely small village where you can find a lot of cows, horses, tourists and many seniors on electric bicycles. Literally, Kolderveen consists of only one street which is almost 2,5 km long. I think with around 200 inhabitants there live many more cows and horses then people. The Netherlands has twelve provinces, Kolderveen belongs to the province Drenthe which lies in the north of the Netherlands. Three of the provinces , included Drenthe, in the north of the Netherlands are well known because of the meadows, farms and sober people compared with the environment of the four biggest cities called the […]

More cows than people

A hidden region between some alpine mountains. On first sight, the Bregenzerwald may seem a bit boring, but well, it isn’t. We got so much more to offer than just cows and cheese, although these are deeply connected to our cultural life. This article should be about my ‘hometown’ and yes, Alberschwende is my ‘hometown’, but it’s actually a small village, inside the Bregenzerwald region, with about 3.300 people living there. Even though I’m not really the biggest fan of Alberschwende there are a few things worth mentioning. The most popular thing of ours may be the ‘KulturKäsKlatsch'”, which could be translated into ‘CultureCheeseClub’. The ‘KäsKlatsch’ takes place every Thursday next to our church. By the way, right behind the […]

My hometown, Vaduz

The capital city of a small country in the heart of Europe. My hometown is called Vaduz and it’s the capital city of Liechtenstein. Liechtenstein has about 38.000 inhabitants and in Vaduz live about 5.500 people. It’s also the town where the royal family of Liechtenstein lives. The royal family lives in the castle, which is located in the city center of Vaduz, although it’s located a little higher than the rest of the houses. We do also have 3 museums in Vaduz: the historical museum, the Hilti art foundation, and the art museum. The art museum and the Hilti art foundation contain a lot of artworks which belong to the royal family of Liechtenstein. There’s also a city train […]
