"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.”"

Redesenho do ADN

https://www.theguardian.com/science/2019/may/15/cambridge-scientists-create-worlds-first-living-organism-with-fully-redesigned-dna

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."

Documentário BBC sobre a chegada do homem à Lua

https://www.bbc.com/news/science-environment-48232627

Citando:
"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."

"“After around six months or a year, if the goods are not sold Amazon will start charging storage fees.

“But the charges are very high so Amazon either throws the goods away or ships them back to China.”


The Sun Online has approached Amazon for further comment."

Apneia

https://www.noticiasdecoimbra.pt/investigadores-de-coimbra-desenvolvem-sistema-inovador-de-diagnostico-da-apneia-do-sono/

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."


Origens do terramoto 1755

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."

Efacec na missão Juicy

Citando:
"A Efacec está a desenvolver a terceira geração do seu monitor de radiação para a missão espacial JUICE rumo ao planeta Júpiter.

Depois de ter colocado a sua tecnologiaem direção ao planeta Mercúrio, a portuguesa Efacec está a desenvolver, entre outros equipamentos, a terceira geração do seu monitor de radiação para a missão JUICE.


O nome da missão de exploração JUICE significa “JUpiter ICy”, numa alusão à exploração do planeta gasoso Júpiter e das suas luas frias."

Microdoses?

https://www.theguardian.com/science/2019/may/03/psychedelic-drugs-women-taking-tiny-doses-hattie-garlick

Citando:
"“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.”"
