Oldest galaxies and the re-ionization period

https://gizmodo.com/the-universes-oldest-galaxies-could-be-right-in-the-mil-1828390203

Citando:
"Atoms started forming from protons and electrons a few hundred thousand years after the Big Bang. The resulting gas cooled, creating stars, but the stars didn’t last long. They exploded in huge supernovae, sending energy out into space. This split the atoms back up once again, “re-ionizing” them. It’s unclear when the first stars started to form or when re-ionization started, but they’re important periods in the Universe’s history, because they set the ball rolling to create the galaxies we see today."

The most widely accepted model says that galaxies are actually visible gas and dust coalescing inside larger haloes of a yet-to-be explained kind of mass called dark matter. Galaxies began forming with the first stars, but during the re-ionization period, astronomers think that temperatures rose too high, halting further galactic growth. Only at some later period, when large-enough dark matter halos coalesced, would the galaxy formation process pick up again."

Conceito novo de aceleração de partículas

Citando:
"AWAKE, which stands for "Advanced WAKEfield Experiment", is a proof-of-principle R&D project investigating the use of protons to drive plasma wakefields for accelerating electrons to higher energies than can be achieved using conventional technologies. Traditional accelerators use what are known as radio-frequency (RF) cavities to kick the particle beams to higher energies. This involves alternating the electrical polarity of positively and negatively charged zones within the RF cavity, with the combination of attraction and repulsion accelerating the particles within the cavity. By contrast, in wakefield accelerators, the particles get accelerated by "surfing" on top of the plasma wave (or wakefield) that contains similar zones of positive and negative charges.

Plasma wakefields themselves are not new ideas; they were first proposed in the late 1970s. "Wakefield accelerators have two different beams: the beam of particles that is the target for the acceleration is known as a 'witness beam', while the beam that generates the wakefield itself is known as the 'drive beam'," "

This appearance was fortuitously chronicled by the ground-based component of NASA’s THEMIS mission (called All‐Sky Imagers), as well as NOAA’s Polar Orbiting Environmental Satellite (NOAA-17), which was overhead as Steve shone"(...)"Light from auroras is caused by particle precipitation, which occurs when high-energy charged particles cascade into the upper atmosphere along Earth’s magnetic field lines. No such high-energy precipitation was observed from the 2008 event. While there was an observed flux of lower-energy particles, that does not explain the vibrancy of Steve’s luminosity and color. By combing through data captured from above and below the purple and green ribbon, the authors concluded that the “skyglow could be generated by a new and fundamentally different mechanism in the ionosphere.”"

"Flashback: Genesis Wrap Up Their Reunion Tour With a Peter Gabriel-Era Classic

But right before they played the final song at the last night of their Turn It On Again reunion tour in 2007, Phil Collins addressed the crowd and spoke from the heart.

“As we stand here right now there is nothing else planned, so that adds a lot more emotion to this evening than this being the last show of the last tour,” Collins told the audience at the Hollywood Bowl. “I’m 56. I joined this band when I was 19, so you can work that out. But Tony [Banks] and Mike [Rutherford] were already in it and they’re older than me. So this is very much a family group. We grew up together. I’ve never said it privately or publicly, but Tony I love you. Mike, I love you too. Now being British, we’re going to carry on with things. That’s enough of that.”

As they did every night of the tour, they then wrapped up the night not with one of their big 1980s pop hits, but rather with “The Carpet Crawlers” from their 1974 prog rock magnum opus The Lamb Lies Down on Broadway. "

"I wanted to take a closer look at what I might be missing out on. Are humans actually predisposed to being screamers, and if so, what is the purpose of all the noise?

Lorraine McCune has been studying the grunt at Rutgers University since 1987. She explained that the grunt is a physiological response to exertion, an epiphenomenon occurring when the body needs more oxygen.

What happens, more or less, is this: “Under conditions of metabolic demand, activation of the intercostal muscles to maintain lung inflation during expiration sets in motion reflex contraction of laryngeal muscles, creating a system under pressure that lengthens the expiration phase of the breath and enhances oxygenation of the blood. Expiration against the constricted glottis produces pulses of sound.”

Translation: In the right circumstances, the sound just happens.

McCune went on to explain that tennis players often grunt when they hit a ball off their racket and that trying to stop the sound can actually hurt their game. “When you squash the grunt,” she said, “you’re having to use energy that you could have used for your stroke to suppress a vocalization.”

There is even a study that proves McCune’s point. Researchers from the University of Nebraska Omaha found that professional players increase the ball’s velocity by 3.8% if they grunt while taking their shot."

""Combining fossil and genomic information, we can use an approach called the 'molecular clock' which is loosely based on the idea that the number of differences in the genomes of two living species (say a human and a bacterium) are proportional to the time since they shared a common ancestor."

By making use of this method the team at Bristol and Mark Puttick from the University of Bath were able to derive a timescale for the history of life on Earth that did not rely on the ever-changing age of the oldest accepted fossil evidence of life.

Co-author Professor Davide Pisani said: "Using this approach we were able to show that the Last Universal Common Ancestor all cellular life forms, 'LUCA', existed very early in Earth's history, almost 4.5 Billion years ago—not long after Earth was impacted by the planet Theia, the event which sterilised Earth and led to the formation of the Moon."

Earth mini-moons (TCO)

Surprisingly, and despite steady improvements to telescope technology, it remains the only known mini-moon, or TCO (temporarily captured orbiter)."

Zonas do universo com poucas galáxias?

https://phys.org/news/2018-08-massive-region-space-astronomers-galaxies.html
Citando:
"Astronomers have known that more than 12 billion years ago, about 1 billion years after the Big Bang, the gas in deep space was, on average, much more opaque than it is now in some regions, although the opacity varied widely from place to place. But they weren't sure about what caused those variations.

To learn why the differences occurred, the astronomers used one of the world's largest telescopes, the Subaru telescope on Mauna Kea in Hawaii, to search for galaxies of young stars in an exceptionally large region of space—500 million light-years across—where they knew the intergalactic gas was extremely opaque.

If the region had an unusually small number of galaxies, the scientists would be able to conclude that starlight could not penetrate as far as expected through the intergalactic gas; if it had an unusually large number of galaxies, the implication would be that the region had cooled significantly over the previous several hundred million years. (Having few galaxies in a region would mean not only that there was less light created by those galaxies, but also that even more opaque gas was being formed, so the light could not travel as far as astronomers had expected.)

"It was a rare case in astronomy where two competing models, both of which were compelling in their own way, offered precisely opposite predictions, and we were lucky that those predictions were testable," said Steven Furlanetto, a UCLA professor of astronomy and a co-author of the research.

The researchers found that region contains far fewer galaxies than expected—clear evidence that starlight could not get through. The paucity of galaxies could be the reason this region is so opaque.

"It is not that the opacity is a cause of the lack of galaxies," Furlanetto said. "Instead, it's the other way around."

They concluded that because the gas in deep space is kept transparent by ultraviolet lightfrom galaxies, fewer nearby galaxies might make it murkier."

Horizontal gene transfer or HGT - genetic matter we don't inherit but acquire sideways, if you please, virally from other organisms, even other species. Roughly 8 percent of the human genome arrived that way. The tree of life is really a web.

"Kukekova first became aware of the celebrated “fox farm experiment” in 1988, when she was still a freshman at Saint Petersburg State University. In 1959, researchers took a group of wild silver foxes (a dark color mutation of the red fox) and bred only the most docile animals—those that didn’t bite when humans stuck fingers in their cages. The scientists then selected the tamest offspring of these animals and repeated the process over and over. By the eighth generation, the foxes started to seek out human company and show affection. (Today, nearly 60 years after the experiment began, some of them even enjoy belly rubs.)

In the 1960s, the scientists also bred a separate strain of foxes, selecting for aggressiveness. Over the generations, those animals were even less friendly toward humans than the other farm-raised foxes, attacking or growling at two-legged visitors as soon as they approached."

It's thought that SIMP J01365663+0933473  is only 200 million years-old and is just 20 light-years away from Earth. It also has a surface temperature of 1,500 degrees Fahrenheit, compared to minus 234 degrees Fahrenheit for Jupiter and 10,000 degrees Fahrenheit for the Sun.

It was first detected using a radio telescope, the  National Science Foundation's Karl G. Jansky Very Large Array."

Mineral nunca visto na terra?

"The mineral came from the Uakit meteorite, named for the Russian location where it was found. Scientists recently presented their discovery of the meteorite's new mineral, named uakitite, at the Annual Meeting of the Meteoritical Society in Moscow.

The researchers found that more than 98 percent of the meteorite consists of kamacite, an alloy of iron and 5 to 10 percent nickel, that's formed in space and is found only in meteorites, which are rocks that fall from space to Earth's surface. The remaining 1 to 2 percent of the meteorite consists of just over a dozen minerals that, for the most part, are exclusively formed in space. On top of that, the composition of the extraordinary space rock suggests that it must have formed under brutally hot temperatures, well over 1,800 degrees Fahrenheit (1,000 degrees Celsius), the researchers said.

"fore my fiancée introduced me to Esther the Wonder Pig — figuratively, not literally — I never could have seen myself trekking all the way up to Canada from my home state of Pennsylvania, future in-laws in tow, to meet a sow best known for a presence on Facebook and Instagram that has earned her an adoring fanbase (including my soon-to-be betrothed). Now that a month has passed and I've returned from my trip to the Happily Ever Esther Farm Sanctuary, where she lives, I find it difficult to eat any meat products without cringing — literally, not figuratively — at the thought of what exactly I'm putting into my body... and, for that matter, my soul."

Edição de genes: 2 versões?

"Why it matters: Cas9 is the first-discovered and most popular enzyme used by the CRISPR technology, but it has been known to have safety concerns. It sometimes unsafely targets the wrong gene or even deletes sections of the genome. However, Cas12a may be safer because it discriminates more strongly against mismatches than Cas9, the scientists say."

"Scientists from two teams reported Wednesday in Nature they were able to use CRISPR-Cas9 gene editing technology to dramatically restructure a yeast cell's complex genome that continued to live but was sometimes unable to reproduce in future generations.

Why it matters: Scientists seek a better understanding of how chromosomes are copied and divided in humans in order to figure out what causes faulty chromosome packages that can trigger miscarriages and some genetic disorders like Down's syndrome. Plus, they want to examine more closely the role played by the number of chromosomes, which differs greatly by species."
