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."
Estrela sai de Via Láctea?
https://www.theguardian.com/science/2019/nov/13/superfast-star-found-leaving-milky-way-at-1700km-per-second
Citando:
"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."

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."

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."

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."

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.”"

"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 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)."

Quoting:
"She tried to do a noble thing, which was to conduct a study into how a man’s penis size is related to his self-esteem and other factors, only to find that the internet responded to her request for pictures (or “dick pics” as the media framed it) accordingly and flooded her with joke images of cartoon characters. She cancelled the study this week, saying the quality of the data had been compromised. I imagine she is royally dicked off."

Citando:
"On Thursday, the European Space Agency (ESA) published a video taken from the International Space Station (ISS) by astronaut Alexander Gerst. The video shows time-lapse footage of the Russian Progress MS-10 cargo spacecraft that launched from the Baikonur cosmodrome in Kazakhstan on November 16. The footage is almost unbelievable as it shows the spacecraft, on a resupply mission to the ISS, arcing into orbit. The camera pans slowly and follows the unmanned Russian craft, revealing Earth’s curvature in epic scale."

"A pair of closely related genetics papers, one published in Science and one in Cell, chronicles the movement of the first humans as they spread across the Americas, venturing both southward and northward and sometimes mixing in with the local populations. The third paper, published in Science Advances, shows what happened to one group of migrants who decided to make the high-altitude Andes their home—a decision that sent them down a unique evolutionary path."
