Dreaming brain rhythms lock in memories It is the clearest evidence to date that REM sleep is critical for memory. By switching off certain brain cells, the researchers silenced a particular, rhythmic type of brain function - without waking the mice. If they did this during REM sleep, the mice failed subsequent memory tests. The research is reported in the journal Science. REM sleep is the phase during which, at least in humans, dreams take place - but the question of whether it is important for settling new memories has been difficult to answer. Recent studies have tended to focus on deep, non-REM sleep instead, during which brain cells fire in various patterns that reflect memory consolidation and "re-play" of the day's experiences. During REM sleep, while our eyes flicker and our muscles relax, exactly what the brain is doing is something of a mystery. But it is a type of sleep seen across the animal kingdom, in mammals and birds and even lizards.

Big Ben’s Culture
Big Ben is a focus of New Year celebrations in the UK, with radio and TV stations tuning to its chimes to welcome the 'official' start of the year. Similarly, on Remembrance Day, the chimes of Big Ben are broadcast to mark the 11th hour of the 11th day of the 11th month and the start of two minutes silence.
For many years ITN's "News at Ten" began with an opening sequence which featured Big Ben with the chimes punctuating the announcement of the news headlines. This has since been dropped, but all ITV1 and ITV News Channel bulletins still use a graphic based on the Westminster clock face. Big Ben can also be heard striking the hour before some news bulletins on BBC Radio 4 and the BBC World Service, a practice that began on December 31, 1923.
The clock features in John Buchan's spy novel The Thirty-Nine Steps and makes for a memorable climax in Don Sharp's 1978 film version, although not in Alfred Hitchcock's 1935 original adaptation. A similar scene is recreated in the 2003 film, Shanghai Knights which culminates with Jackie Chan hanging from the hands of the clock. The clock also appears in the animated cartoon Basil, the Great Mouse Detective.
An earlier film climax on the clock face of Big Ben appears in Will Hay's 1943 film My Learned Friend, although the scene is more slapstick than thriller. Available in: <http://saberingles.com.ar/reading/big-ben.html> Access in: julho de 2015.

Zika virus makes Rio Olympics a threat in Brazil and abroad, health expert says
Amir Attaran calls for postponement or moving of Games and says biggest risk is spreading the virus to countries without adequate healthcare infrastructure. As Brazil reels from a spiraling political crisis and its deepest recession in decades, a public health specialist in Canada has added to the country’s woes with a high-profile call for the 2016 summer Olympics – slated to kick off in Rio de Janeiro in early August – to be postponed or moved due to the Zika outbreak. Speaking to the Guardian on Thursday, Attaran described the idea of going ahead with the games as both “indescribably foolish” and “monstrously unethical”. The potential risks to visitors range from brain-damaged children to death in rare instances, he added. “Is this what the Olympics stand for?” Adapted from: http://www.theguardian.com/world/2016/may/12/rio-olympics-zika-amir-attaran-public-health-threat

Coca-Cola history began in 1886 when the curiosity of an Atlanta pharmacist, Dr. John S. Pemberton, led him to create a distinctive tasting soft drink that could be sold at soda fountains. He created a flavored syrup, took it to his neighborhood pharmacy, where it was mixed with carbonated water and deemed “excellent” by those who sampled it. Dr. Pemberton’s partner and bookkeeper, Frank M. Robinson, is credited with naming the beverage “Coca-Cola” as well as designing the trademarked, distinct script, still used today. Prior to his death in 1888, just two years after creating what was to become the world’s #1-selling sparkling beverage, Dr. Pemberton sold portions of his business to various parties, with the majority of the interest sold to Atlanta businessman, Asa G. Candler. Under Mr. Candler’s leadership, distribution of Coca-Cola expanded to soda fountains beyond Atlanta. In 1894, impressed by the growing demand for Coca-Cola and the desire to make the beverage portable, Joseph Biedenharn installed bottling machinery in the rear of his Mississippi soda fountain, becoming the first to put Coca-Cola in bottles. Large scale bottling was made possible just five years later, when in 1899, three enterprising businessmen in Chattanooga, Tennessee secured exclusive rights to bottle and sell Coca-Cola. The three entrepreneurs purchased the bottling rights from Asa Candler for just $1. Benjamin Thomas, Joseph Whitehead and John Lupton developed what became the Coca-Cola worldwide bottling system.

O airbag (“bolsa de ar”) é um equipamento de segurança obrigatório em muitos países que já ajudou a salvar muitas vidas em acidentes de carro. Segundo um levantamento feito pelo Instituto de Segurança do Trânsito dos Estados Unidos, desde que o airbag se tornou obrigatório, no ano de 1995, até o ano de 2007, ele ajudou a salvar mais de 15 mil pessoas. Essas bolsas são feitas de um material bastante reforçado, que costuma ser o polímero náilon, que é bem resistente. No interior dessa bolsa, há uma mistura de reagentes: azoteto de sódio (NaN3), nitrato de potássio e dióxido de silício. No momento da colisão, sensores localizados em pontos estratégicos do carro detectam a forte desaceleração do veículo e são acionados, emitindo sinais para uma unidade de controle, que checa qual sensor foi atingido e, assim, aciona o airbag mais adequado. O sensor é ligado a um filamento que fica em contato com uma pastilha de azoteto de sódio dentro do airbag. Ele emite então uma faísca ou descarga elétrica, que aquece o azoteto, fornecendo a energia de ativação necessária para dar início à reação demonstrada a seguir, que libera grande quantidade de gás nitrogênio (N2).
