Uma tonelada de hidrofluorocarboneto-23 emitida para a atmosfera é equivalente a 12 mil toneladas de dióxido de carbono. Um dos mais potentes gases com efeito de estufa, o hidrofluorocarboneto-23 (HFC-23), está a aumentar a um ritmo elevado na atmosfera, concluíram cientistas da Universidade de Bristol, no Reino Unido, num estudo publicado na revista Nature Communications. A concentração de HFC-23 na atmosfera está a crescer para níveis recorde, apesar de as emissões globais terem sido alegadamente eliminadas em 2017, porque, embora poucas aplicações industriais, é libertado durante a produção de outro químico usado em sistemas de refrigeração em países como a China e Índia. Uma tonelada deste gás emitida para a atmosfera é equivalente a 12 mil toneladas de dióxido de […]

Equipa de cientistas em Portugal está a desenvolver um programa de inteligência artificial para analisar lesões cancerosas com mais precisão e prever a eficácia dos tratamentos. As más notícias chegam e uma pessoa fica a saber que tem cancro. Seguem-se mais exames às lesões, como ressonâncias magnéticas, que serão depois analisados pelos médicos para se saber quais serão os tratamentos a fazer. E se a este processo se pudesse acrescentar uma análise com mais precisão? A pensar nisso, uma equipa de cientistas em Portugal está a desenvolver um programa de inteligência artificial que analisará imagens das lesões fornecidas pelos exames para além do que o olho humano consegue ver. No final, ao dar informações sobre a gravidade da doença e […]

The strongman, Jón Páll Sigmarsson, changed Iceland’s athletic standing on the world stage forever. The 1980s were a defining time for Icelandic sport. It was during this decade that the Icelander Jón Páll Sigmarsson secured his international reputation as a legendary strongman, weightlifter, and bodybuilder. Thanks to the combination of his superhuman athletic abilities and his charismatic on-screen personality, Jón Páll won the hearts of not only Icelanders but people around the world, who tuned in to see him win the World’s Strongest Man four times (in 1984, 1986, 1988 and 1990) and quip his catchy slogans such as: “Þetta er ekkert mál fyrir Jón Pál! [This is no haul for John Paul!]”, delivered just before a deadlift. Jón Páll […]

Argumentação surge em artigo publicado na revista Science. Cientistas querem que o conceito de áreas marinhas protegidas móveis seja consagrado na Convenção das Nações Unidas sobre a Lei do Mar (UNCLOS), como nova ferramenta de protecção ambiental face às alterações climáticas. Num artigo que será publicado esta sexta-feira na revista científica Science, investigadores consideram que o processo de actualização da UNCLOS que está em curso, o primeiro desde a assinatura da convenção em 1982, é uma “oportunidade única” para introduzir a ideia de zonas protegidas que acompanhem as espécies à medida que se deslocam. “Como é óbvio os animais movimentam-se, muitos deles circulam por vastas áreas de oceano. À medida que as alterações climáticas se instalam e alteram ecossistemas, se […]

Conselho Nacional de Educação propõe mudanças na abordagem que é feita nas escolas à educação ambiental. Partindo do pressuposto de que a despolitização da discussão dos problemas ambientais não é só um exercício artificial, como também uma forma de desvalorizar esta problemática enquanto “questão cívica”, o Conselho Nacional de Educação (CNE) exorta a que se admita “a inevitabilidade de uma dimensão política da educação ambiental” que é proposta nas escolas. Numa recomendação que foi agora divulgada, aquele órgão de consulta do Parlamento e do Governo frisa que na Estratégia Nacional para a Educação Ambiental 2020, lançada pelo Governo em 2017, “a expressão ‘política’ parece apenas referir-se aos decisores e às medidas do lado do Estado, não sugerindo explicitamente a existência […]

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 […]

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 […]

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 […]

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 […]

Like in most Central European countries, Christmas in Poland is a quaint and much-beloved affair. Most of the Polish Christmas celebrations take place on 24th December, and even though the day isn’t an official public holiday in Poland, to many Poles it is one of the most significant and family-oriented dates in the calendar. Many institutions stop working earlier than usual on the day of Christmas Eve, which is usually celebrated with a family dinner at home. Many Poles wait until the first star appears in the sky before sitting down to eat on 24th December. This tradition commemorates the Star of Bethlehem, which according to the New Testament guided the Wise Men to the birthplace of Christ. Nowadays, with […]
