Recuperação da camada de ozono

Se continuar a ser lançado CFC 11 para a atmosfera de forma contínua, isso pode contribuir para o atraso da recuperação da camada de ozono durante mais de uma década. Em 2018, verificou-se que a taxa de declínio do clorofluorocarboneto (CFC) 11 tinha abrandado 50% desde 2012, o que significava que esta substância proibida em todo o mundo estava a ser lançada na atmosfera. Já este ano, confirmou-se que essas emissões vinham sobretudo de duas províncias chinesas: Shandong e Hebei. Agora, uma equipa de cientistas do Reino Unido e dos Estados Unidos simulou o que acontecerá se o CFC 11 continuar a ser lançado. Num artigo científico publicado na revista científica Nature Communications, refere-se que a recuperação da camada de […]

Aleksander Doba

A Polish kayaker has known primarily for his long voyages crossing the ocean Aleksander Doba (born 9 September 1946) is a Polish kayaker known primarily for his long voyages crossing oceans. In 2010 and again in 2013 he kayaked across the Atlantic Ocean westward under his own power. The two voyages were the longest open-water kayak voyages ever made. He was named 2014 Adventurer of the Year by National Geographic. In 2017 he completed an eastward kayaking trip across the Atlantic. Doba was the first person to paddle a 7-meter sea kayak across the Atlantic ocean, a voyage that spanned 5394 kilometers. Doba’s first voyage from Senegal to Brazil in 2010 set a record for the longest open-water crossing ever […]

DNA em “chiclete” com 5700 anos

Pela primeira vez, os cientistas conseguiram extrair um antigo genoma humano completo a partir de um achado que não era um osso, mas um pequeno pedaço de alcatrão de bétula com 5700 anos. São menos de três centímetros de alcatrão de bétula mastigado por uma mulher há muito, muito tempo, mas foi o suficiente para retirar um genoma humano completo da amostra encontrada no Sul da Dinamarca. A partir deste pedaço de antiga chiclete com 5700 anos os cientistas traçam o retrato provável de uma mulher de pele morena, cabelo escuro e olhos azuis que baptizaram com o nome de Lola. Os resultados da análise revelados na revista Nature Communications fornecem ainda algumas pistas sobre a evolução das bactérias e […]

Christmas in Germany

Silent night, holy night – Christmas in Germany When the air starts smelling like roasted almonds, when the city center is immersed in warm lights and when children start to sing their hearts out on the streets, then you know it`s time for one of the most important German Christmas traditions: The Christmas Market. The idea of this pre-Christmas market originates in the Late Middle Ages when people bought goods to prepare for the cold wintertime. Throughout the years also craftsmen, toymakers and confectioners were allowed to sell their products, contributing to the Christmas market as it is today. Traditionally, the market starts in the last week of November and lasting until Christmas Eve. A very curious thing about this […]

Alcatifa sustentável e portuguesa

A alcatifa é feita a partir de materiais têxteis reciclados e, no final do evento, é novamente transformada noutros produtos de gama mais baixa. Uma empresa da Guarda começou este ano a produzir uma alcatifa reciclável, feita a partir de excedentes têxteis, roupas e desperdícios industriais, para utilização específica em recintos de eventos. A startup Karpet2R – Walking to the Future surgiu por iniciativa de Pedro Tavares e João Gonçalves, que também gerem uma empresa de organização de eventos. Segundo Pedro Tavares, a startup de produção de alcatifas recicladas surgiu após verificar que, no final de cada evento organizado, as alcatifas de polipropileno utilizadas eram deitadas fora. “Estamos a falar de quilos e quilos que, no fundo, iam para o […]

Time before Christmas in Germany

Some traditions have moved into the background in recent years and others are still very important for the people. Our Christmas starts with the Advent season. It starts four weeks before Christmas day on a Sunday. There we light the first candle from our Advent wreath and every Sunday until Christmas we will light one more candle. So, at Christmas, all four candles will be lit on the Advent wreath. During this time, we have another celebration. On the 6th of December Saint Nicholas visits our houses. He was the bishop of Myra and this is why he has a bishop’s hat and a bishop’s stick. In my hometown, we have this tradition that all girls in the last year […]

Viriato e Lusitânia

Viriato e Lusitânia, eis os nomes escolhidos por Portugal para um exoplaneta e a sua estrela. O exoplaneta agora baptizado foi descoberto por uma equipa liderada pelo astrofísico português Nuno Santos. Para comemorar o 100.º aniversário da União Astronómica Internacional (IAU, na sigla em inglês), mais de 110 países organizaram campanhas nacionais para atribuírem nomes a exoplanetas e às suas estrelas hospedeiras. Os resultados desta iniciativa, a IAU100 Name ExoWorlds (Dê Nome a ExoMundos, em português), foram anunciados esta terça-feira numa conferência em Paris. Em Portugal, os nomes escolhidos foram Lusitânia (para a estrela) e Viriato (para o exoplaneta). Esta proposta partiu, de forma independente, de três escolas de Braga, Pombal e da Maia. “Observações astronómicas durante a última geração […]

Christmas traditions in Ireland

Ireland has a wide number of Christmas traditions steeped in the Gaelic and Catholic heritage of the country. A tradition that was very widespread in the 1970s but which seems to be dying out somewhat and especially in urban areas is the candle in the window. Symbolically the candle represented a welcome to Joseph and Mary as they wandered in search of lodgings. The candle indicated to strangers and especially to the poor that there may be an offering of food in the house within. During the penal times in Ireland Catholic priests were forbidden to perform mass so the candle would also show people passing by that the person in the house was a Catholic believer and mass could […]

Transportes públicos e ambiente

A criação do PROTransP tem como objectivo “aumentar a oferta de transporte colectiv23o nas comunidades intermunicipais e nos territórios de baixa densidade” O ministro do Ambiente e da Acção Climática disse nesta segunda-feira esperar “um aumento muito expressivo” do transporte público fora das duas áreas metropolitanas (Porto e Lisboa) devido ao novo programa de 15 milhões de euros criado pelo Governo. “Acho que, ao longo próximo ano, e nos anos seguintes, vamos assistir a um aumento muito expressivo dos territórios fora das áreas metropolitanas”, explicou João Pedro Matos Fernandes, em declarações aos jornalistas à margem da cerimónia dos 70 milhões de clientes do Metro do Porto em 2019.

Christmas in Scotland

Scottish Christmas traditions are very recent because Christmas did not become a public holiday in Scotland until 1958. In 1640 an act in the Scottish Parliament banned the celebration of Christmas, then called Yule. This was because of the Reformation, which saw the country breaking with the Catholic Church and developing a national Kirk (church) which was influenced by Presbyterian outlooks. The attitudes towards celebrations changed after the Reformation leading to them outlawing the celebration of Christmas festivities. Christmas was, therefore, a quiet affair for many years; which meant that Hogmanay (New Year’s Eve) was the biggest festival for the Scottish. Hogmanay includes many traditions such as “first-footing” which is to be the first person to visit a friend after […]

Madeira in the summer

The way there doesn’t even seem long because of the nice views. If I would have to describe the perfect summer day in Madeira, it would be something like this. Waking up before the sun is up, taking breakfast with me and going by car to Pico do Areeiro with a group of friends. There we would sit on the second highest point of Madeira and eat breakfast while watching the sunrise. After that, we would drive down the mountain through the beautiful Madeiran forest. Next stop would be Santana. There we would go visit the Madeira theme park. Of course, the park is pretty touristic, but spending a few hours there with friends could be fun. Seeing the typical […]

Vereda da Ponta de São Lourenço

There you can see huge cliffs reaching out of the sea. This eastern peninsula of the island is from volcanic origins, it consists mostly basalt stone but also limestone sediment formations. Because of the pretty dry climate and the exposure to northern winds, there is low vegetation. It looks very different from the other parts of the island and this is what makes it so special. A nice fact is that the name of the vereda comes from the name of João Gonçalves Zarco’s caravel, São Lourenço. Zarco was one of the three discoverers of Madeira. For me, this walk is definitely one that you NEED to do when you are in Madeira, it’s one of the most beautiful walks […]

How not waste a summer in Madeira

Let me give you some non-qualified tips for the months to come. To be honest, I have not been in Madeira during the hottest months of summer. My experience started in September what I would still call summer due to the heat. Madeira is very versatile and full of possible activities. That is the reason why I love this island. People who love the sea have several options to explore the Atlantic Ocean. Snorkeling and scuba diving let you discover the biodiversity of the sea dwellers. But not everyone likes to dive in the dark and deep ocean and some rather stay above the surface of the water, at least with their heads. There are still enough activities, such as […]

Vincent van Gogh

Vincent van Gogh: of the most famous artists of the 19th century. This fame is not only because his art, but also because of his life. He was born in 1853, in a village near the Belgian border. When starting adulthood he did not really know what to do. He first became a schoolteacher, then a book salesman, studied theology and became a preacher in a coal mine. He did not really do well in all these jobs and got fired for all of them. Eventually, his brother Theo convinced Vincent to become an artist after seeing the sketches he made. He moved around in the Netherlands, Belgium, and Paris before eventually moving to the village of Arles in France, […]

Jan Matejko

Jan Matejko is probably the most known Polish painter. He born in 1838 in Krakow and he specialized in historical and battle paintings. One of his most famous canvas is “The Battle of Grunwald”, painted in 1872–1878.
