The Sun is defying forecasts

The Sun's activity is defying forecasts and highlighting how difficult it is to predict the machinations of Earth's nearest star.

Why it matters: Space weather, which is largely driven by the Sun, can shorten the lifespans of satellites, cause radio blackouts and, in extreme solar storms, bring down power grids.

. . .

  • Sunspots — dark areas on the face of the Sun — can spit out major solar flares that sometimes come with coronal mass ejections (CMEs), bursts of electrically charged plasma that can interfere with satellites, electrical grids and supercharge the auroras.
  • If coronal holes — cooler spots in the Sun's atmosphere — rotate into the view of Earth, they can send extremely fast solar winds into our part of space, warping Earth's magnetic fields in the process.

Yes, but: The Sun is extremely complicated and even after decades of study, researchers don't understand exactly how it works.

Rare cosmic collision acted like one of the ‘factories of gold’ in the universe

“When we followed this long gamma-ray burst, we expected it would lead to evidence of a massive star collapse,” Fong said. “Instead, what we found was very different. When I entered the field 15 years ago, it was set in stone that long gamma-ray bursts come from massive star collapses. This unexpected finding not only represents a major shift in our understanding, but also excitingly opens up a new window for discovery.”

Neutron stars are compact cosmic objects, so researchers never expected them to contain enough material to create a gamma-ray burst that could last nearly a minute.

The explosion occurred in a galaxy about 1 billion light-years away from Earth. Since the event happened relatively close, astronomically speaking, astronomers used multiple telescopes to glean unprecedented detail.

“We found that this one event produced about 1,000 times the mass of the Earth in very heavy elements. This supports the idea that these kilonovae are the main factories of gold in the Universe,” said Dr. Matt Nicholl, an associate professor at the University of Birmingham in the UK and coauthor of one of the Nature Astronomy studies, in a statement.

Scientists Find No Evidence That Depression Is Caused by “Chemical Imbalance” or Low Serotonin Levels

After decades of research, there remains no clear evidence that serotonin levels or serotonin activity are responsible for depression, according to a comprehensive review of prior research led by University College London (UCL) scientists.

The major new umbrella review – an overview of existing meta-analyses and systematic reviews – was published on July 20 in the journal Molecular Psychiatry. It suggests that depression is not likely caused by a chemical imbalance, and calls into question what antidepressant medications do. This is because most antidepressants are selective serotonin reuptake inhibitors (SSRIs), which were originally said to function by correcting abnormally low serotonin levels. In fact, there is no other accepted pharmacological mechanism by which antidepressants affect the symptoms of depression.

Lead author Professor Joanna Moncrieff, a Professor of Psychiatry at UCL and a consultant psychiatrist at North East London NHS Foundation Trust (NELFT), said: “It is always difficult to prove a negative, but I think we can safely say that after a vast amount of research conducted over several decades, there is no convincing evidence that depression is caused by serotonin abnormalities, particularly by lower levels or reduced activity of serotonin.

. . .

Professor Moncrieff said: “Our view is that patients should not be told that depression is caused by low serotonin or by a chemical imbalance, and they should not be led to believe that antidepressants work by targeting these unproven abnormalities. We do not understand what antidepressants are doing to the brain exactly, and giving people this sort of misinformation prevents them from making an informed decision about whether to take antidepressants or not.”

The Instagram Guru 'Fucking' His Female Followers 'To Freedom'

Although his teachings consisted of fairly generic spiritual koans, he looked nothing like a typical ethereal guru: On Instagram, he regularly showed off his fondness for cigars and fine blended whiskeys. He often posted photos of himself with his tanned arm snaked around the waists of one or more waifish, mermaid-haired women. And with his toned biceps, and Zack Morris-esque swoop of sun-kissed hair, he more closely resembled a pampered surfer boy whose dad had paid his way into Stanford than a spiritual leader.

. . .

Yet if you probe beneath the surface, Massaro’s teachings seem to bear the distinct mark of a dark messianic complex. He has openly stated he can “teleport, bilocate, and levitate”; he allegedly prescribes restrictive fasts and diets, which cult experts say helps keep followers malleable (a claim he denies); he has sex with female followers as a way to reward them and to punish them for apparent misdeeds, according to two women I spoke with who’d had relationships with him; and his teachings skew toward open misogyny, instructing followers on the strict dichotomy of traditional gender roles and urging women to resist their more active “masculine” impulses, writing in one 2016 post that femininity is defined by “radiance and surrender.” (It’s worth noting that strict gender dichotomies are common in cults, with the self-improvement organization NXIVM espousing a similar ideology.)

. . .

Massaro’s expanding influence is “very concerning,” says Diane Benscoter, a former Moonie and the founder of Antidote.ngo, an organization that helps those affected by psychological manipulation. According to Benscoter, Massaro’s teachings have “a real appeal for people who feel lost, who feel like they’re missing something, who are looking for love and looking for acceptance and looking for friends and community. They’re going to be really susceptible to this, and the cost could be years of their lives, or it could be worse.”

Octopuses were around before dinosaurs, fossil find suggests

Scientists have found the oldest known ancestor of octopuses – an approximately 330m-year-old fossil unearthed in Montana.

The researchers concluded the ancient creature lived millions of years earlier than previously believed, meaning that octopuses originated before the era of dinosaurs.

The 4.7-inch (12-cm) fossil has 10 limbs – modern octopuses have eight – each with two rows of suckers. It probably lived in a shallow, tropical ocean bay.

“It’s very rare to find soft tissue fossils, except in a few places,” said Mike Vecchione, a Smithsonian National Museum of Natural History zoologist who was not involved in the study. “This is a very exciting finding. It pushes back the ancestry much farther than previously known.”

Ancient Footprints Suggest Humans Lived In The Americas Earlier Than Once Thought

The question of when humans first migrated to North America has long been a matter of hot debate among researchers who have continually uncovered evidence of ever-earlier dates. Now, analysis of ancient fossilized human footprints in New Mexico has pushed the date back once again — to at least 21,000 years ago.

Writing in the journal Science, a team of researchers led by Matthew Bennett of Bournemouth University in England examined a set of human footprints preserved on an ancient lakeshore in New Mexico's White Sands National Park, a location now known for its expansive — and dry — chalk-colored dunes.

They concluded that the footprints were made between 21,000 and 23,000 years old. The date would place human habitation in the Americas during the Last Glacial Maximum and at least 5,000 years earlier than widely accepted evidence has yet suggested.

World's oldest known beer factory may have been unearthed in Egypt

American and Egyptian archaeologists have unearthed what could be the oldest known beer factory at one of the most prominent archaeological sites of ancient Egypt, a top antiquities official said on Saturday.

Mostafa Waziri, secretary general of the Supreme Council of Antiquities, said the factory was found in Abydos, an ancient burial ground located in the desert west of the Nile River, more than 450km (280 miles) south of Cairo.

He said the factory apparently dates back to the region of King Narmer, who is widely known for his unification of ancient Egypt at the beginning of the first dynastic period (3150BC-2613BC).

Archaeologists found eight huge units – each is 20 metres (about 65ft) long and 2.5 metres (about 8ft) wide. Each unit includes about 40 pottery basins in two rows, which were used to heat a mixture of grains and water to produce beer, Waziri said.

Why The Jupiter And Saturn Conjunction During The 2020 Winter Solstice Is Extra Special

A rare celestial event will help mark the Winter Solstice in the northern hemisphere on Monday, Dec. 21.

Jupiter and Saturn are currently appearing very close together from an earthly vantage point. These two gas giants are in conjunction, an occurrence that happens every 20 years or so.

This one though, is extra special.

“Really, really close conjunctions like this one are quite rare," said Hal Bidlack with the Colorado Springs Astronomical Society. "We haven’t been able to observe Jupiter and Saturn this close since the year 1226. And we won’t see them again this close for decades and decades to come.”

The two planets were last about this close together in the year 1623. But the pairing occurred while the planets were close to the sun from earth's perspective, Bidlack said, and the sight was basically washed out in the sun’s glare.

Will a Church Get Away With Making a Teen Listen to Recording of Her Rape?

The victim was 15 years old when she says church elders called her into a room with her mother and stepfather, sat her down, and made her listen to a recording of her own rape. A lifelong Jehovah’s Witness, the girl—who we’ll call Anna—says she was sexually assaulted by an older church member on multiple occasions. But when the church learned of it, they decided to investigate not her assailant, but her—for the crime of having sex outside of marriage. And now it’s down to the Utah Supreme Court to decide if they should get away with it.

The court cases rests on the question of eccleiastical abstention, or whether the court can intervene in matters of religion. The Kingdom Hall of Jehovah’s Witnesses of Roy, Utah, claims it was engaging in regular religious practice when it forced the teenager to relive to her own rape. And so far, the courts have agreed. But lawyers for the woman, now in her late 20s, argue that their conduct is so “utterly intolerable” that it transcends this rule.

. . .

In court filings, the church disputes Anna’s factual allegations and denies mistreating her “in any manner,” while at the same time describing her interrogation as a “common and accepted religious practice.” Anna, it claims, “voluntarily associated with the religious organization and chose to participate in the judicial tribunal with her parents”—something that, they argue, “would not ordinarily cause severe unmanageable mental distress.” At a hearing last week, a Supreme Court justice described the practice as akin to “emotional waterboarding.” A lawyer for the church said she would draw the line at anything physical.

Pennsylvania Catholic diocese files for bankruptcy amid sexual abuse lawsuits

A Pennsylvania Catholic diocese on Wednesday filed for bankruptcy in the midst of facing several sexual abuse lawsuits against priests.

The Diocese of Harrisburg is the first Catholic diocese in the state to seek bankruptcy protection after a 2018 investigation revealed more than 300 priests had allegedly sexually abused more than 1,000 children in Pennsylvania.

. . .

The statute of limitations in Pennsylvania forbids almost all of the victims named in the 2018 report from suing alleged abusers, The Washington Post reported. But the state Superior Court recently ruled that some victims can sue dioceses, even if the statute prevents them from suing the alleged abusive priests.

This decision sparked several new lawsuits to be filed against the Harrisburg Diocese, which Haverstick told the Post was “something that we considered” when deciding to file for bankruptcy. The bankruptcy would freeze all lawsuits, and any compensation for the victims would become a part of those proceedings.

Leader of Alleged Sex Cult NXIVM Hit With Child Porn Charges

Keith Raniere, the founder of an alleged sex-cult that masqueraded as a self-help organization, has been hit with yet another charge, per Reuters: child pornography.

In March 2018, Raniere was arrested and charged with sex trafficking for his involvement in NXIVM, an organization that allegedly brainwashed, manipulated, and blackmailed women into being “sex slaves.” He also, according to new court filings, coerced underage girls into his operation. At a Brooklyn hearing on Wednesday, federal prosecutors said that Raniere had sex with a 15-year-old girl who later became his first “slave,” and that he had a sexual relationship with at least one other child.

. . .

In the year since Raniere’s arrest, a growing number of individuals with ties to the operation have been arrested and faced charges. NXIVM’s foundation has also increasingly cracked. In April, Smallville actress Allison Mack, who claims she instituted the ritual of branding sex slaves with Raniere’s initials, was arrested and charged with sex trafficking and forced labor; and in July, Seagram heiress Clare Bronfman, former bookkeeper Kathy Russell, and co-founder Nancy Salzman and her daughter, Lauren Salzman, were charged with racketeering conspiracy for their involvement in a criminal organization. (Since Raniere’s arrest, he’s also been charged with forced labor, wire fraud conspiracy, and human trafficking.)

And, just hours before Raniere was hit with the most recent child pornography charges, Nancy Salzman plead guilty to her racketeering charge, making her the first person from the operation to be convicted. In the courtroom, SFGate reports that she broke down, saying, “It has taken me some time and some soul-searching to come to this place.”

Focus on the Children

The Catholic Church is exposed. A number of wide-ranging, deeply researched reports of molestation, rape, abuse, corruption, and concealment have been released in close enough time to one another that the magnitude of the horror might actually—for the average American, anyway—sink in. It all feels monumental, if also powered in part by coincidence. The recently published Pennsylvania report, in which a grand jury details the sexual abuse of more than 1,000 children by more than 300 priests and systematically argues that church officials were complicit, was two years in the making. It didn’t need to be released two weeks before BuzzFeed published Christine Kenneally’s yearslong investigation into the abuse of children—some of whom didn’t survive—by nuns and priests at St. Joseph’s Catholic orphanage. But it was, and the effects of those stories are stacking up. These two reports came out just three months after every Chilean bishop offered to resign over a massive sex abuse scandal, and a year or so after Netflix documentary series The Keepers revisited an unsolved murder and allegations of abuse in a Baltimore Catholic school. That these are all different—but all cover the same institutional atrocity—is the kind of perfect storm that may get us to focus in ways that the abuse of tens of thousands of children worldwide has not managed to. Humans find numbers like that hard to absorb.

But we respond well to drama, and there are two competing stories right now about the Catholic Church. Call it the people vs. the palace. Alongside this tide of testimony from long-suffering victims and determined investigators, there’s the theater of ex–papal nuncio Carlo Maria Viganò’s “memo” calling for (among other things) the resignation of Pope Francis. Viganò is a hard-line conservative known for helping to arrange Pope Francis’ notorious meeting with anti-gay-marriage activist Kim Davis—which exacerbated tensions Pope Francis and Viganò. (The pope has been generally rather accepting of homosexuality; his U.S. visit included a private audience with a gay man and his partner.) Viganò timed his memo to catch the pope at a strategic weak point. Already reeling from the church scandals, Pope Francis was also visiting Ireland, which recently legalized abortion, indexing a growing distance from the faith. He was vulnerable. If this political maneuvering feels gilded and distasteful, it should. The more you read of the abuses, and of church officials shrugging it off, the less interesting the petty details of Vatican palace intrigue become. Of course the abuse of children would become yet another occasion for liberals and conservatives to plot against each other.

Did the dystopian ‘Matrix’ movies predict the rise of Trump?

“Welcome to the desert of the real,” Morpheus (Laurence Fishburne) ostentatiously tells Neo (Keanu Reeves) in an important scene not quite halfway through “The Matrix,” the groundbreaking 1999 science fiction film written and directed by Lana and Lilly Wachowski. (Who were then known, let us note, as Andy and Larry, the “Wachowski Brothers.”) Neo has of course taken the “red pill” and discovered that what he took to be reality is actually a computer simulation, used by a malignant machine intelligence to enslave the human race.

As most fans of the “Matrix” movies surely know, Morpheus’ expression has both a prehistory and a long-tail legacy. My point here, however, is that “The Matrix” and the currents of postmodern theory and dystopian sci-fi that informed it didn’t just predict the future but also seemingly shaped it.

We’re all lost in the desert of the real now. We all believe we took the red pill — but how can we be sure it wasn’t a placebo? Many of us, like the treacherous rebel played by Joe Pantoliano in the movie, long to climb back inside the Matrix, where we can live within the comforting illusions of yesteryear. But there’s no door that leads there, and no there on the other side of the nonexistent door.

That phrase comes from an extended metaphor in Jean Baudrillard’s “Simulacra and Simulation,” an influential (if borderline unreadable) work of critical theory that was partly an inspiration for “The Matrix” and partly just a prop. Neo has a copy on his bookshelf early in the film, or at least he appears to: In a joke Baudrillard may or may not have appreciated, the book has actually been hollowed out and used to conceal a disk of illicit data. For that matter, it only exists inside the Matrix — it’s a fake book in a fake universe.

New Research Claims Bones Found 80 Years Ago On Pacific Atoll Likely Amelia Earhart's

There is no shortage of speculation on what became of legendary American aviator Amelia Earhart, who disappeared in 1937 over the Pacific during an attempt to circumnavigate the globe.

Now, Richard Jantz, a researcher affiliated with the University of Tennessee, has re-examined data from bones found on a remote atoll three years after Earhart vanished and has determined they very likely belonged to her.

Three main theories about Earhart's disappearance — arguably the most enduring aviation mystery in history — have been bandied about over the years.

. . .

He took a closer look at data gathered in 1940 from skeletal remains recovered by a British expedition to Nikumaroro. The British found a human skull, humeri and radii (both arm bones), a tibia and fibula from the lower leg and two femurs (thigh bones). The bones were sent to Fiji, where they were examined and measured by physician D.W. Hoodless.

Lunar trifecta: Rare 'super blue blood moon' will light the sky this week

Set your alarms, space fans -- if you can drag yourself out of bed on Wednesday, you're in for a treat.

The pre-dawn hours of January 31 will play host to an incredibly rare celestial convergence -- a "super blue blood moon."

. . .

So, a "supermoon" is when a full moon occurs at the same time as its perigee, the closest point of the moon's orbit with Earth. The result: the moon appears larger than normal and NASA is predicting this one will be 14% brighter than usual.

Chances are you have used the phrase "once in a blue moon" -- but have you ever wondered where it came from? The well-known idiom actually refers to the rare instance when there is a second full moon in a calendar month. The first supermoon of 2018 -- which took place on New Year's Day -- was previously described by NASA as the "biggest and brightest" one expected for the entire year.

Then completing this "lunar trifecta" is the "blood" element. Although it does not have a scientific definition, a "blood moon" occurs during a lunar eclipse when faint red sunbeams peek out around the edges of the Earth, giving it a reddish, copper color.

A robot that once said it would 'destroy humans' just became the first robot citizen

An empty-eyed humanoid named Sophia has become the first robot to be granted citizenship in the world.

Saudi Arabia bestowed citizenship on Sophia ahead of the Future Investment Initiative, held in the kingdom's capital city of Riyadh on Wednesday.

[Moderator and journalist Andrew Ross] Sorkin told Sophia that "we all want to prevent a bad future," prompting Sophia to rib Sorkin for his fatalism.

"You've been reading too much Elon Musk. And watching too many Hollywood movies," Sophia told Sorkin. "Don't worry, if you're nice to me, I'll be nice to you. Treat me as a smart input output system."

Lakes of mercury and human sacrifices – after 1,800 years, Teotihuacan reveals its treasures


In 2003, a tunnel was discovered beneath the Feathered Serpent pyramid in the ruins of Teotihuacan, the ancient city in Mexico. Undisturbed for 1,800 years, the sealed-off passage was found to contain thousands of extraordinary treasures lying exactly where they had first been placed as ritual offerings to the gods. Items unearthed included greenstone crocodile teeth, crystals shaped into eyes, and sculptures of jaguars ready to pounce. Even more remarkable was a miniature mountainous landscape, 17 metres underground, with tiny pools of liquid mercury representing lakes. The walls of the tunnel were found to have been carefully impregnated with powdered pyrite, or fool’s gold, to give the effect in firelight of standing under a galaxy of stars.

The archaeological site, near Mexico City, is one of the largest and most important in the world, with millions of visitors every year. This was its most exciting development for decades – and the significance of these new discoveries is explored in a major exhibition opening this month at the de Young Museum in San Francisco.

Teotihuacan has long been a place of mysteries. It was the most populous city in the Americas nearly 2,000 years ago, but little is known about its language, rulers or the circumstances of its collapse, in around AD550. Its name, which means “birthplace of the gods”, was given much later by the Aztecs, who treated the ruins – including the monumental Pyramids of the Sun and Moon and the majestic Avenue of the Dead – with due reverence.

Many questions remain unanswered, but the newly discovered tunnel has led to a greater understanding of the design and mythology of Teotihuacan, which was a sacred place as well as a bustling metropolis. The de Young exhibition, as well as showcasing artworks from numerous collections, offers the latest theories about the mysteries that still surround it.

Cats Domesticated Themselves, Ancient DNA Shows

In true feline form, cats took their time deciding whether to jump into humans’ laps.

In a new comprehensive study of the spread of domesticated cats, DNA analysis suggests that cats lived for thousands of years alongside humans before they were domesticated. During that time, their genes have changed little from those of wildcats, apart from picking up one recent tweak: the distinctive stripes and dots of the tabby cat.

Researchers surveyed the DNA of more than 200 cats spanning the last 9,000 years, including ancient Romanian cat remains, Egyptian cat mummies, and modern African wildcat specimens. Two major cat lineages contributed to the domestic feline we know today, they report in a study published Monday in Nature Ecology & Evolution.

The earlier ancestors of today’s domestic cats spread from southwest Asia and into Europe as early as 4400 B.C. The cats likely started hanging around farming communities in the Fertile Crescent about 8,000 years ago, where they settled into a mutually beneficial relationship as humans’ rodent patrol. (See little-known small cats in “Out of the Shadows, the Wildcats You’ve Never Seen.”)

The Weird Little Industry Behind a Mesmerizing Instrument

Josiah Collett, a 10-year-old autistic boy from Broxbourne, England, had always struggled with social interactions. But things were getting worse. In school, his peers told him that he shouldn’t be alive. He spent nights crying, unable to explain to his parents what had happened.

“He was retreating into his own world,” his mother Georgia told me. “We couldn’t get through to him, and he couldn’t get through to us.”

During a family vacation to Belgium, the Collett family heard a “gorgeous, hypnotic sound” coming from the distance. They followed it down the street and found a busker playing something that looked like a cross between a caveman tool and a flying saucer. The busker tapped the instrument, called a “handpan,” which emitted both drum-like rhythms and delicate harmonies.

The mix of percussion and melody intrigued Georgia, Josiah’s mother. Josiah was always preternaturally talented when it came to music—he taught himself to play drums when he was two years old—and Georgia wondered if this new instrument, which so resembled a drum but was more expressive, might be good for Josiah.

Broken Brain


The Brain Literally Starts Eating Itself When It Doesn't Get Enough Sleep

The reason we sleep goes far beyond simply replenishing our energy levels every 12 hours - our brains actually change states when we sleep to clear away the toxic byproducts of neural activity left behind during the day.

Weirdly enough, the same process starts to occur in brains that are chronically sleep-deprived too - except it's kicked into hyperdrive. Researchers have found that persistently poor sleep causes the brain to clear a significant amount of neurons and synaptic connections, and recovering sleep might not be able to reverse the damage.

A team led by neuroscientist Michele Bellesi from the Marche Polytechnic University in Italy has examined the mammalian brain's response to poor sleeping habits, and found a bizarre similarity between the well-rested and sleepless mice.

. . .

Think of it like the garbage being cleared out while you're asleep, versus someone coming into your house after several sleepless nights and indiscriminately tossing out your television, fridge, and family dog.
