Citando:
"Food-based dietary guidelines - Brazil

Official name

Dietary Guidelines for the Brazilian Population 2014 (Portuguese: Guia alimentar para a população brasileira2014)

Publication year

Brazil published the first version of its dietary guidelines in 2006. A revised version was launched in 2014.

Process and stakeholders

The development process of the ‘Dietary Guidelines for the Brazilian Population 2014’ was led by the Ministry of Health and the Center for Epidemiological Research in Nutrition and Health of the University of São Paulo (NUPENS/USP), with the support of the Brazilian Pan American Health Organization Office.

The guidelines were elaborated in a participatory manner and in consultation with multiple sectors of the society. In the first stage, a series of workshops to elaborate and evaluate the first draft were held with experts from various sectors including health, education, social protection and agriculture, as well as researchers and representatives of civil society groups (leaders of professional councils and professional associations and members of public policy social control councils and consumer protection organizations). Following those meetings, a second draft of the guidelines was presented for public consultation in a website platform run by the Ministry of Health.

In the second stage, the Ministry of Health and the NUPENS/USP finalized the guidelines, having taken into account the comments from the public consultation."

Neurónios artificiais?

Citando:
"Os investigadores conseguiram replicar as dinâmicas naturais em ratos, usando chips de silicone.

“Até agora, os neurónios eram como caixas negras, mas conseguimos abri-la e espiá-la por dentro. O nosso trabalho altera paradigmas porque fornece um método robusto para reproduzir as propriedades elétricas dos neurónios reais em detalhes mínimos”, disse o autor do estudo, Alain Nogaret.

O investigador realça ainda que uma das vantagens da sua inovação é que os seus neurónios precisam de pouca energia (140 nanowatts)."

Velocidade de expansão do universo?

https://www.theguardian.com/science/2019/nov/02/hubble-constant-mystery-that-keeps-getting-bigger-estimate-rate-expansion-universe-cosmology-cepheid
Citando:
"The other method for establishing the Hubble constant has involved astronomers looking at the rippling pattern of light, called the cosmic microwave background, that formed just after the big bang birth of the cosmos 13.8bn years ago. This background has been surveyed with increasing precision by US and European satellites – most recently by the European Space Agency’s Planck observatory – and these observations have allowed scientists to build a model that takes account of dark energy and dark matter and that shows how the early universe’s growth would probably have produced an expansion that astronomers can measure today."

"Astronomers have spotted a star heading out of the Milky Way at more than 6m km/h (3.7m mph), or 1,700km per second, after an encounter with the supermassive black hole at the centre of the galaxy.

The star is moving so fast that in about 100m years it will exit the Milky Way and spend the rest of its life sailing alone through intergalactic space. Although it was predicted 30 years ago that black holes could fling stars out of the galaxy at phenomenal speeds, it is the first time that such an event has been recorded."

2019-11: Fotógrafo Robert Freeman morre aos 82 anos

Autor das fotos das capas de álbuns como o With The Beatles, Help e Rubber Soul:
https://news.sky.com/story/robert-freeman-photographer-behind-classic-beatles-album-dies-11858114

Citando:
"Paul McCartney and Ringo Starr have paid tribute to the photographer behind some of The Beatles most famous album covers, who has died aged 82.

Robert Freeman helped define the band's image, especially with the 1963 cover for With The Beatles - their second album.


The black and white picture featured simple head shots of the Fab Four in part shadow.


It was also used for the 1964 US album Meet The Beatles!"

"According to the space agency, citizen scientist Kevin M. Gill used readings captured by the Juno spacecraft to create the striking image. Juno’s on-board imaging technology recorded the data while traveling some 5,300 miles (8,500 kilometers) over the clouds on November 3, 2019.

While the planet, a gas giant, is composed mostly of hydrogen and helium, NASA says that scientists suspect that some of the strange coloring in the storm clouds could come from sulfur or phosphorus gases that originate within Jupiter."

O clitóris e a reprodução?

https://www.theguardian.com/lifeandstyle/shortcuts/2019/nov/06/the-truth-about-the-clitoris-why-its-not-just-built-for-pleasure

Citando:
"A feminist case was powerfully made by philosopher Elisabeth Lloyd in The Case of the Female Orgasm. When we seek to characterise sexual pleasure in women as an aid to fertility, we are turning it into an adaptive mechanism, any pleasure a by-product to the service of the species.

We are also being androcentric, taking the male reproductive journey (have orgasm; produce sperm; make baby) and trying to find its mirror in the female (have orgasm; grab sperm; make baby). If you want to explore female sexuality meaningfully, you have to see it as its own terrain, in which pleasure quite possibly exists for its own sake, irrespective of such a mechanism being absent in men."

Voyager 2 e a heliosfera

https://www.theguardian.com/science/2019/nov/04/nasa-voyager-2-sends-back-first-signal-from-interstellar-space

Citando:
"The second set of measurements, by Voyager 2, give new insights into the nature of the heliosphere’s limits because on Voyager 1 a crucial instrument designed to directly measure the properties of plasma had broken in 1980.

Measurements published in five separate papers in Nature Astronomy reveal that Voyager 2 encountered a much sharper, thinner heliosphere boundary than Voyager 1. This could be due to Voyager 1 crossing during a solar maximum (activity is currently at a low) or the craft itself might have crossed through on a less perpendicular trajectory that meant it ended up spending longer at the edge."

"De acordo com a investigação, cujos resultados foram publicados na revista científica especializadas Proceedings of the National Academy of Sciences, em causa estão estranhas pistas encontradas em algumas rochas no Canadá.

Estas rochas revelam indícios de uma extinção massiva e até então desconhecida de organismos maior do que a dos dinossauros, que há 65 milhões de anos ditou o fim destes animais e fez a Terra perder quase três quartos das suas plantas e animais.

A extinção antiga agora descoberta envolveu microrganismos que moldaram a atmosfera da Terra, abrindo depois caminho para o aparecimento de animais maiores.“

“Com a agricultura surge o conceito de propriedade. Os meus animais, a minha colheita. E surge a herança. Eu tenho que ter a certeza absoluta de que o filho é meu. A partir da agricultura a mulher torna-se uma propriedade”."

O trabalho manual e a Apolo 11

https://www.fastcompany.com/90363966/the-guts-of-nasas-pioneering-apollo-computer-was-handwoven-like-a-quilt

Citando:
"If the internals of the Apollo computer itself needed to be hand sewn, so be it.

And so, like the lunar rover wheels and the parachutes, the circuits and programs of the Apollo flight computers were also woven by hand, by women at a Raytheon factory in Waltham, Massachusetts. They sat at sophisticated looms, using long needles with wire attached to them instead of thread, carefully weaving the wiring that was the programming of the computers.


The software was, in fact, hardware.


It was an astonishing process that was tedious yet required absolute attention and precision. Every single 1 and 0 in the computer’s memory required a wire in exactly the right place. A single mis-wired strand meant the computer’s programs wouldn’t work properly—and might fail at some critical, potentially disastrous moment.


The women who did this work had, in fact, been recruited from nearby textile factories. The memory holding the programming for a single Apollo flight computer—for the entire mission—was a total of just 73 kB, far less than the memory many emails require today. Yet it took dozens of women in Waltham eight weeks to assemble it, meticulously, by hand."

(...)

"The Apollo guidance computer was the first operational computer to use rope-core memory. By the time U.S. lunar modules starting landing on the Moon, the technology had moved on to the much easier to handle—and much cheaper—computer chips and floppy disks that dominated computing for the next several decades.

So the Apollo flight computer was not only the first computer of any significance to use handwoven rope core memory. It was also the last."

Citando:
"“[O que ele escreve] não é o tipo de coisas pela qual se ganhe um Pulitzer ou reconhecimento internacional, porque os assuntos sobre os quais escreve são demasiado locais e obscuros para a audiência global. Não há nada de dramático nos seus artigos: são investigações secas, sem emoção, densas, que nos dão a sensação de que nos estamos a afundar quando chegamos ao final”, escrevia o editor num texto de opinião publicado pelo “The Guardian”. “Podíamos saber que aquela ou outra indústria tinham problemas, mas não sabíamos ao certo quantos problemas até o Golunov mergulhar no trabalho. É isso que lhe dá pica: encontrar algo que era um segredo, compreender como funciona e contá-lo ao mundo.”

A fonte com que G o l u n o v se iria encontrar prometera-lhe informação sobre o negócio da morte e dos funerais na capital russa. Desconfia-se que importantes nomes da política de Moscovo possam estar de ligados aos esquema. Pouco após a sua detenção, a polícia divulgou oito fotografias com a droga apreendida e com um laboratório supostamente no apartamento do jornalistas. Mas as imagens foram públicas durante pouco tempos e, algumas horas depois, haveriam de desaparecer da página do Ministério do Interior."

"Commander Armstrong told Mission Control: “Houston, it’s been a real change for us.

“Now we’re able to see stars again and recognise constellations for the first time on the trip.

“It’s – the sky is full of stars. Just like the night side of Earth.

“But all the way here, we’ve only been able to see stars occasionally and perhaps through the monocular but not recognise any star patterns"


NASA astronaut Bruce McCandless, who was communicating with Apollo 11, replied: “I guess it's turned into night up there really, hasn't it?.”


Commander Armstrong silly replied that it “really has”.


About 30 minutes later, NASA’s Mission Control read out the day’s news headlines to the astronauts alongside some messages from their families.

Mr McCandless said: “West Germany has declared Monday to be Apollo Day. School children in Bavaria have been given the day off.

“Post Office clerks have been encouraged to bring radios to work and Frankfurt is installing TV sets in public places.”"

Citando:
"More than 18,000 edits later, the scientists had removed every occurrence of the three codons from the bug’s genome. The redesigned genetic code was then chemically synthesised and, piece by piece, added to E coli where it replaced the organism’s natural genome. The result, reported in Nature, is a microbe with a completely synthetic and radically altered DNA code. Known as Syn61, the bug is a little longer than normal, and grows more slowly, but survives nonetheless."

"In the making of 13 Minutes to the Moon, we spent the best part of four weeks travelling around the United States looking for the people who, one day in 1969, had somehow got a man safely to the surface of another world.

In Texas, we found Charlie Duke, lunar module pilot on Apollo 16, and Walt Cunningham, who served as command module pilot during Apollo 7, the inaugural test flight.

In Chicago, we interviewed the legendary Jim Lovell, who orbited the Moon in 1968 on the audacious flight of Apollo 8, and of course later commanded the ill-fated Apollo 13.

The very first of our interviews for the series was with Michael Collins who, along with Neil Armstrong and Buzz Aldrin, completed the crew of Apollo 11 on the mission that saw human beings land on the Moon for the very first time in the summer of 1969."

Sobre a raiva

https://www.theguardian.com/lifeandstyle/2019/may/12/science-of-anger-gender-age-personality

Citando:
"What is anger?

Scientists believe that the capacity for anger has been hardwired into the brain over millions of years of evolution. It forms part of our instinct to fight off threats, to compete for resources and to enforce social norms. Anger is rooted in the brain’s reward circuit. We are constantly – often subconsciously – weighing up what we expect to happen in any situation. When there is a mismatch between what we’ve learned to expect and the hand we’re dealt, our brain’s reward circuit sounds the alarm and activity is triggered in a small almond-shaped region in the brain called the amygdala.


Anger can trigger the body’s fight or flight response, causing the adrenal glands to flood the body with stress hormones, such as adrenaline, and testosterone, preparing us for physical aggression. But whether we actually end up swearing or scowling or even punching someone depends on a second brain area, the prefrontal cortex, that is responsible for decision-making and reasoning. This puts our anger in context, reminds us to behave in socially acceptable ways and for most of us, most of the time, keeps our primal instincts in check."

Citando:
"Coimbra (CHUC).

Os investigadores procuram encontrar um biomarcador para a apneia do sono, ao mesmo tempo que é estudada a relação entre esta doença e o envelhecimento.


“O Síndrome da Apneia Obstrutiva do Sono (SAOS) constitui uma das perturbações do sono mais comuns, tendo como consequências uma sonolência diurna elevada, que diminui o bem-estar, e o aparecimento de doenças crónicas como diabetes, doenças cardiovasculares e demência”, refere Cláudia Cavadas, do Centro de Neurociências e Biologia Celular (CNC), da Universidade de Coimbra.


A investigadora adianta que, segundo estimativas, “80-90% dos casos de SAOS não tenham sido ainda diagnosticados, e, como tal, não estejam a ser devidamente acompanhados e tratados”.


Atualmente, o diagnóstico da doença é feito com recurso a um estudo cardiorrespiratório domiciliário (utilizado em mais de 95% dos casos) ou através da polissonografia, um estudo mais completo realizado em contexto hospitalar."

https://www.publico.pt/2019/05/07/ciencia/noticia/largo-costa-portuguesa-estar-surgir-fonte-sismos-violentos-1871724

Citando:
"A procura pela resolução do enigma da fonte do terramoto de 1755 levou um investigador português a confirmar uma anomalia na crosta terrestre ao largo da costa portuguesa que pode explicar por que ocorrem sismos violentos numa zona aparentemente calma.

João Duarte, da Faculdade de Ciências da Universidade de Lisboa, disse à agência Lusa que, a confirmar-se, a descoberta muda a percepção sobre o risco sísmico ao largo da costa portuguesa, que vem de uma zona chamada planície abissal da Ferradura, situada a 250 quilómetros a sudoeste do cabo de São Vicente.


“É o local de início de um processo de subducção, em que uma placa cai por baixo ou se descasca”, conhecido nas margens do oceano Pacífico e em zonas de grande actividade sísmica, como o Japão, disse o investigador do Departamento de Geologia."

"“I’ll take a very small dose, every three or four days,” she says, weighing out a thumbnail of powder on digital jewellery scales, purchased for their precision. “People take well over a gram recreationally. I weigh out about 0.12g and then just swallow it, like any food. It gives me an alertness, an assurance. I move from a place of anxiety to a normal state of confidence, not overconfidence.”

Over the last 12 months, I have been hearing the same story from a small but increasing number of women. At parties and even at the school gates, they have told me about a new secret weapon that is boosting their productivity at work, improving their parenting and enhancing their relationships. Not clean-eating or mindfulness but microdosing – taking doses of psychedelic drugs so tiny they are considered to be “subperceptual”. In other words, says Rosie: “You don’t feel high, just… better.”"

"Investigadores da Universidade Autónoma de Madrid descobriram que o cérebro continua a produzir neurónios ao longo da vida. A pesquisa, publicada na revista Nature Medicine na segunda-feira, chegou à conclusão de que já nascemos com a maioria das nossas células cerebrais, mas os cientistas encontraram neurónios novos ou “imaturos” até à nona década de vida.

Isso confirmaria a neurogénese, ou seja, a formação de novos neurónios."

Naufrágio no Nilo é a primeira prova de que Heródoto não estava a mentir sobre os barcos egípcios - ZAP

Naufrágio no Nilo é a primeira prova de que Heródoto não estava a mentir sobre os barcos egípcios - ZAP



Citando:

"Segundo o ScienceAlert, este sistema havia sido visto em representações e modelos durante o período faraónico, mas não havia nenhuma evidência arqueológica da sua existência. Pelo menos, até agora.

Os arqueólogos exploraram o Navio 17, da cidade portuária de Thonis-Heracleion, agora submersa, perto da Boca Canópica do Nilo, datada do Período Tardio do Egito (664-332 a.C.). Apesar de estar submerso há, pelo menos, 2.000 anos, o Navio 17 tem revelado segredos sem preço. Aliás, os cientistas conseguiram descobrir 70% do seu casco.
“Quando descobrimos este naufrágio, percebemos que Heródoto estava certo“, disse Damian Robinson, arqueólogo do Centro de Arqueologia de Oxford, ao The Guardian."

ESA GOCE mission

http://m.esa.int/Our_Activities/Observing_the_Earth/GOCE/Taking_gravity_from_strength_to_strength

Citando:
"Ten years ago, ESA launched one of its most innovative satellites. GOCE spent four years measuring a fundamental force of nature: gravity. This extraordinary mission not only yielded new insights into our gravity field, but led to some amazing discoveries about our planet, from deep below the surface to high up in the atmosphere and beyond. And, this remarkable mission continues to realise new science today.

Because of factors such as the planet’s rotation, the position of mountains and ocean trenches and different densities in materials in Earth’s interior, the force of gravity at Earth’s surface varies from place to place."

Hum... The global... Hum?

The Earth gum is not tinnitus. So they say:

Citando:
"He added: “While it must be stressed time and again that there are many sounds created by human activity that can sound like the Hum, and it takes some effort and knowledge to track those sounds down. They range from electrical noise, pumps, industrial machinery, and so on. Once we eliminate those sources, we are left with the worldwide phenomenon that I am studying.”"

A grande morte?

E o motivo:
https://zap.aeiou.pt/o-que-matou-a-vida-marinha-243505

Citando:
"Agora, os cientistas mostraram o que erradicou a vida marinha: o aumento das temperaturas acelerou o metabolismo das criaturas, aumentando as suas necessidades de oxigénio, ao mesmo tempo que esgotou o oxigénio dos oceanos. Como resultados, os animais literalmente sufocaram.

O problema é que, atualmente, estamos a vivenciar um aquecimento atmosférico muito semelhante – e muito mais rápido."

A música e o efeito no cérebro

https://www.technologynetworks.com/neuroscience/news/how-music-activates-our-brains-reward-center-315391
Citando:
"If you love it when a musician strikes that unexpected but perfect chord, you are not alone. New research shows the musically unexpected activates the reward center of our brains, and makes us learn about the music as we listen.

Researchers led by Ben Gold, a PhD candidate in the lab of Robert Zatorre at The Neuro (Montreal Neurological Institute and Hospital), of McGill University, put 20 volunteers through a musical reward learning task. Each participant chose a color, then a direction. Each choice came with a certain probability of leading to either a consonant, pleasurable, musical excerpt or a dissonant, unpleasurable one. Over time the subjects learned which choices were more likely to produce both consonant and dissonant music. The test was designed to create an expectation of either musical enjoyment or dissatisfaction. Subjects performed this task while their brain activity was measured with functional magnetic resonance imaging (MRI)."

Nova galáxia descoberta

http://sci.esa.int/hubble/61075-hubble-fortuitously-discovers-a-new-galaxy-in-the-cosmic-neighbourhood-heic1903/

Citando:
"An international team of astronomers recently used the NASA/ESA Hubble Space Telescope to study white dwarf stars within the globular cluster NGC 6752. The aim of their observations was to use these stars to measure the age of the globular cluster, but in the process they made an unexpected discovery.

In the outer fringes of the area observed with Hubble's Advanced Camera for Surveys a compact collection of stars was visible. After a careful analysis of their brightnesses and temperatures, the astronomers concluded that these stars did not belong to the cluster – which is part of the Milky Way – but rather they are millions of light-years more distant.

Our newly discovered cosmic neighbour, nicknamed Bedin I by the astronomers, is a modestly sized, elongated galaxy. It measures only around 3000 light-years at its greatest extent – a fraction of the size of the Milky Way. Not only is it tiny, but it is also incredibly faint. These properties led astronomers to classify it as a dwarf spheroidal galaxy."

Replicação de ADN melhor compreendida

https://zap.aeiou.pt/cientistas-misterio-adn-replica-234368

Citando:
"observaram três sequências ao longo da molécula de ADN que se tocavam com frequência.

(dr) Sima et al


Foi então que decidiram usar a tecnologia de edição genética CRISPR para remover essas três áreas simultaneamente. Com esta experiência, os cientistas descobriram que esses três elementos juntos eram a chave para a replicação do ADN. “A remoção destes três elementos mudou o tempo de replicação do segmento desde o início até ao fim do processo”, afirmou Gilbert."

Mais detalhes da missão chinesa

https://www.theguardian.com/world/2019/jan/04/china-change-4-moon-rover-jade-rabbit-2-sets-off

Citando:
"The moon’s far side is sometimes known as the dark side, although it is not darker than the near side in any literal sense. It undergoes the same phases of illumination by the Sun as the side facing Earth. But because the moon spins on its axis at exactly the same rate as it orbits Earth, one side remains permanently out of view.

It was only in 1959, when the first images of the far side were beamed back by the Soviet Union’s Luna 3, that intriguing differences were revealed. The far side is pockmarked by more craters and appears almost devoid of the seas of solidified lava, known as maria, that form the shadowy shape of a face that we see from Earth."
