Will Mankind Destroy Itself?
Theoretical physicist Michio Kaku sees two major trends today. One eventually leads to a multicultural, scientific, tolerant society that will expand beyond Earth in the name of human progress. The other trend leads to fundamentalism, monoculturalism, and -- eventually -- civilizational ruin. Whichever of these two trends wins out will determine the fate of mankind. No pressure, everyone.

Reading the Bible (Or the Koran, Or the Torah) Will Make You an Atheist
Author and magician Penn Jillette was asked to leave his Christian youth group by a pastor who told his parents: "He's no longer learning about the Bible from me. He is now converting everyone in the class to atheism." The reason? Jillette did his homework and was turned off by the hostilities of the text. It can be intimidating to come out as an atheist, especially in a religious community. Jillette found that having "out" atheist role models helped him feel unalone.

James Gleick on the Common Character Traits of Geniuses
This video is part of a series on female genius, in proud collaboration with 92Y's 7 Days of Genius Festival.
The personalities of Isaac Newton and Richard Feynman were, on one level, extremely different. Biographer and former New York Times reporter James Gleick says Newton was argumentative, had few friends, and likely died a virgin. Feynman, on the other hand, loved dancing and going to parties, and had many friends in the scientific community. But in regards to their working habits, both men were solitary and had the ability to concentrate with a sort of intensity that is hard for mortals to grasp. At bottom, Gleick says geniuses tend to have a yearning for solitude which, though fruitful for their professional work, made the task of daily living more burdensome.

- The fibula was originally discovered in 1989, though at the time scientists believed the damaged bone had been fractured.
- After reanalyzing the bone, and comparing it with fibulas from a human and another dinosaur, a team of scientists confirmed that the dinosaur suffered from the bone cancer osteosarcoma.
- The study shows how modern techniques can help scientists learn about the ancient origins of diseases.
An interdisciplinary team of scientists has confirmed for the first time that dinosaurs suffered from cancer.
The team made the discovery after reanalyzing a 76-million-year-old fibula, or lower leg bone, that belonged to a Centrosaurus apertus, a four-legged dinosaur that was as tall as a human and about 18 feet long. Paleontologists first discovered the fossilized fibula in 1989, in Alberta, Canada. They observed that the bone was damaged, but assumed it was due to a healing fracture.
After seeing the fossil at the Royal Tyrrell Museum of Paleontology in Alberta in 2017, David Evans, the James and Louise Temerty endowed chair of vertebrate paleontology at the Royal Ontario Museum, and his colleagues suspected the damage was caused by a malignant tumor.
"The cancerous bone is severely malformed, with a massive gnarly tumor larger than an apple in the middle of the bone," Evans told Gizmodo. "In fact, the top half of the bone is missing, and it may have broken in life due [to] the progress of the cancer."

In the recent study, the team used a combination of techniques to analyze the fibula, including taking CT scans, casting the bone and studying thin slices of it under a microscope. The analysis suggested that the dinosaur likely suffered from osteosarcoma, a type of bone cancer that affects modern humans, typically young adults.
For further evidence, the team compared the damaged fibula to a healthy fibula from a dinosaur of the same species, and also to a fibula that belonged to a 19-year-old human who suffered from osteosarcoma. Both comparisons supported the osteosarcoma diagnosis.
Evans et al.
"The shin bone shows aggressive cancer at an advanced stage," Evans said in a press release. "The cancer would have had crippling effects on the individual and made it very vulnerable to the formidable tyrannosaur predators of the time."
"The fact that this plant-eating dinosaur lived in a large, protective herd may have allowed it to survive longer than it normally would have with such a devastating disease."
The fossilized fibula was originally unearthed in a bonebed alongside the remains of dozens of other Centrosaurus apertus, suggesting the dinosaur didn't die from cancer, but from a flood that swept it away with its herd.

The new study highlights how modern techniques can help scientists learn more about the evolutionary origins of modern diseases, like cancer. It also shows that dinosaurs suffered through some of the same terrestrial afflictions humans face today.
"Dinosaurs can seem like mythical creatures, but they were living, breathing animals that suffered through horrible injuries and diseases," Evans said, "and this discovery certainly makes them more real and helps bring them to life in that respect."

Malcolm Gladwell is the author of five New York Times bestsellers: The Tipping Point, Blink, Outliers, What the Dog Saw, and David and Goliath. His newest book, Talking to Strangers (2019), is a darker-than-usual look at the miscommunications and assumptions that occur when we interact with people we don't know, told through historical case studies like Sandra Bland, Bernie Madoff, and Adolf Hitler. Gladwell is also the co-founder of Pushkin Industries, an audio content company that produces the podcasts Revisionist History, which reconsiders things both overlooked and misunderstood, and Broken Record, where he, Rick Rubin, and Bruce Headlam interview musicians across a wide range of genres. Gladwell has been included in the TIME 100 Most Influential People list and touted as one of Foreign Policy's Top Global Thinkers.
Maria Konnikova is the author of two New York Times bestsellers: The Confidence Game and Mastermind: How to Think Like Sherlock Holmes. Her new book is The Biggest Bluff (June 2020). While researching The Biggest Bluff, journalist Konnikova became an international poker champion and the winner of over $300,000 in tournament earnings—and inadvertently turned into a professional poker player. She is a regular contributing writer for The New Yorker, and her writing has been featured in Best American Science and Nature Writing and has been translated into over twenty languages. Maria also hosts the podcast The Grift from Panoply Media, a show that explores con artists and the lives they ruin, and is currently a visiting fellow at NYU's School of Journalism. She graduated from Harvard University and received her PhD in psychology from Columbia University.
With that knowledge, they can then estimate the cards still in the deck, and those most likely to be dealt out next, all to help each player decide how to place their bets, and as a team, gain an advantage over the dealer.
This calculating strategy, known as card-counting, was made famous by the MIT Blackjack Team, a group of students from MIT, Harvard University, and Caltech, who for several decades starting in 1979, optimized card-counting and other techniques to successfully beat casinos at blackjack around the world — a story that later inspired the book "Bringing Down the House."
Now researchers at MIT and Caltech have shown that the weird, quantum effects of entanglement could theoretically give blackjack players even more of an edge, albeit a small one, when playing against the house.
In a paper published this week in the journal Physical Review A, the researchers lay out a theoretical scenario in which two players, playing cooperatively against the dealer, can better coordinate their strategies using a quantumly entangled pair of systems. Such systems exist now in the laboratory, although not in forms convenient for any practical use in casinos. In their study, the authors nevertheless explore the theoretical possibilities for how a quantum system might influence outcomes in blackjack.
They found that such quantum communication would give the players a slight advantage compared to classical card-counting strategies, though in limited situations where the number of cards left in the dealer's deck is low.
"It's pretty small in terms of the actual magnitude of the expected quantum advantage," says first author Joseph Lin, a former graduate student at MIT. "But if you imagine the players are extremely rich, and the deck is really low in number, so that every card counts, these small advantages can be big. The exciting result is that there's some advantage to quantum communication, regardless of how small it is."
Lin's MIT co-authors on the paper are professor of physics Joseph Formaggio, associate professor of physics Aram Harrow, and Anand Natarajan of Caltech, who will start at MIT in September as assistant professor of electrical engineering and computer science.
Entanglement is a phenomenon described by the rules of quantum mechanics, which states that two physically separate objects can be "entangled," or correlated with each other, in such a way that the correlations between them are stronger than what would be predicted by the classical laws of physics and probability.
In 1964, physicist John Bell proved mathematically that quantum entanglement could exist, and also devised a test — known a Bell test — that scientists have since applied to many scenarios to ascertain if certain spatially remote particles or systems behave according to classical, real-world physics, or whether they may exhibit some quantum, entangled states.
"One motivation for this work was as a concrete realization of the Bell test," says Harrow of the team's new paper. "People wrote the rules of blackjack not thinking of entanglement. But the players are dealt cards, and there are some correlations between the cards they get. So does entanglement work here? The answer to the question was not obvious going into it."
After casually entertaining the idea during a regular poker night with friends, Formaggio decided to explore the possibility of quantum blackjack more formally with his MIT colleagues.
"I was grateful to them for not laughing and closing the door on me when I brought up the idea," Formaggio recalls.
In blackjack, the dealer deals herself and each player a face-up card that is public to all, and a face-down card. With this information, each player decides whether to "hit," and be dealt another card, or "stand," and stay with the cards they have. The goal after one round is to have a hand with a total that is closer to 21, without going over, than the dealer and the other players at the table.
In their paper, the researchers simulated a simple blackjack setup involving two players, Alice and Bob, playing cooperatively against the dealer. They programmed Alice to consistently bet low, with the main objective of helping Bob, who could hit or stand based on any information he gained from Alice.
The researchers considered how three different scenarios might help the players win over the dealer: a classical card-counting scenario without communication; a best-case scenario in which Alice simply shows Bob her face-down card, demonstrating the best that a team can do in playing against the dealer; and lastly, a quantum entanglement scenario.
In the quantum scenario, the researchers formulated a mathematical model to represent a quantum system, which can be thought of abstractedly as a box with many "buttons," or measurement choices, that is shared between Alice and Bob.
For instance, if Alice's face-down card is a 5, she can push a particular button on the quantum box and use its output to inform her usual choice of whether to hit or stand. Bob, in turn, looks at his face-down card when deciding which button to push on his quantum box, as well as whether to use the box at all. In the cases where Bob uses his quantum box, he can combine its output with his observation of Alice's strategy to decide his own move. This extra information — not exactly the value of Alice's card, but more information than a random guess — can help Bob decide whether to hit or stand.
The researchers ran all three scenarios, with many combinations of cards between each player and the dealer, and with increasing number of cards left in the dealer's deck, to see how often Alice and Bob could win against the dealer.
After running thousands of rounds for each of the three scenarios, they found that the players had a slight advantage over the dealer in the quantum entanglement scenario, compared with the classical card-counting strategy, though only when a handful of cards were left in the dealer's deck.
"As you increase the deck and therefore increase all the possibilities of different cards coming to you, the fact that you know a little bit more through this quantum process actually gets diluted," Formaggio explains.
Nevertheless, Harrow notes that "it was surprising that these problems even matched, that it even made sense to consider entangled strategy in blackjack."
Do these results mean that future blackjack teams might use quantum strategies to their advantage?
"It would require a very large investor, and my guess is, carrying a quantum computer in your backpack will probably tip the house," Formaggio says. "We think casinos are safe right now from this particular threat."

- An orgasm is described as a feeling of intense pleasure that happens during sexual activity.
- By studying the brain activity of people experiencing orgasms, researchers have been able to pinpoint some of the key changes that occur.
- These changes include heightened sensitivity to areas of the brain that control how we feel pain, making us less sensitive to it.
An orgasm is described as a feeling of intense pleasure that happens during sexual activity. While some people experience orgasms differently than others, there are some key changes that occur in the mind and body.
By studying the brain activity of people experiencing orgasms, researchers have been able to pinpoint some of these key changes that occur. Using fMRI machines (functional magnetic resonance imaging) or PET scans (positron emission tomography), were able to measure blood flow and neuron activity inside the brain during climax.
What really happens in the brain during orgasm?
The hypothalamus, which plays a key role in releasing hormones like dopamine and oxytocin, is one of the regions of the brain that lights up during orgasm.

Does the "logical" part of your brain shut down? That's hotly debated.
There may be a reason why you feel bold and uninhibited during your climax.
"The lateral orbitofrontal cortex becomes less active during sex. This is the part of the brain that is responsible for reason, decision making, and value judgments. The deactivation of this part of the brain is also associated with decreases in fear and anxiety," explains clinical psychologist Daniel Sher.
However, not all experts in the field agree with this widely publicized study's findings. Recent (2017) research suggests otherwise, with results that show that these areas of the brain did not deactivate within the 10 female participants of this study.
Parts of your brain associated with memories, touch, and movement may light up.
Research has found that the hypothalamus, thalamus, and substantia nigra may light up during orgasm. "Dirty Minds: How Our Brains Influence Love, Sex and Relationships" author Kayt Sukel was interviewed for her work alongside researchers who studied the effect of an orgasm on the brain while she was in an MRI machine.
The thalamus helps integrate information about touch, movement, and sexual memories/fantasies. This could explain how you call upon sexual memories and fantasies (or why your imagination is able to be more active) during sexual arousal and peak.
Oxytocin builds up and is released.
Oxytocin is defined as a "bonding" hormone. The forming of oxytocin during sex happens in the pituitary glands and it is then released in the hypothalamus. The hypothalamus plays a key role in many important functions including the releasing of other hormones (like dopamine), regulation of body temperature, controlling of appetite, and of course, the management of sexual behaviors.
A surge of dopamine is released.
During orgasm, your brain works hard to produce various hormones, like the aforementioned oxytocin. In that cocktail of hormones is dopamine, which is released at the moment of orgasm. Dopamine is responsible for feelings of pleasure and desire and therefore acts as a motivation to keep experiencing those feelings of pleasure and desire.
Dopamine is formed in the part of the brain that receives information from several other areas in order to define if your needs (specifically your human needs) are being satisfied.
The release of endorphins, oxytocin, and vasopressin make you less sensitive to pain during sex.
For many, pain and sex go hand in hand. Many people enjoy a little bit of pain during sex, and there is actually a very good reason for this: you're less susceptible to pain during sex. The pituitary gland is activated during sex, which then frees your brain up to release all kinds of endorphins that are able to promote pain reduction.
An interesting thing to note is that some of the same areas of the brain that are active during sex are also active when you experience pain. A very interesting 1985 study looked at the correlation between vaginal stimulation and the elevation of pain.
In people who are unable to feel genital stimulation, the brain may actually be able to "remap" itself.
People who have suffered lower-body paralysis can still achieve orgasm through stimulation of other body parts such as the nipples. In this case, the brain actually creates new pathways to pleasure that doesn't involve our genitalia. This Seattle Times article details paralyzed women who were able to rediscover their ability to orgasm through various other sensations.
Having orgasms can keep your brain healthy.
Because there is a significant increase in blood flow across multiple areas of the brain so dramatically when we achieve orgasm, it's entirely likely that orgasms may have developed in part to keep our brains healthy.

Your body swells and becomes more sensitive.
While men experience the obvious swelling in the genitals due to increased blood flow, women can experience some forms of swelling during sex as well. From your breasts to your vulva, many women experience swelling during sexual arousal and release.
Your heart rate quickens, which leads to euphoria.
Of course, your heart rate elevates when you're experiencing orgasm, but along with that, you also experience a blood pressure rise and your breathing rate also increases. Both of these things are considered mild aerobic activity responses and could factor into the kind of euphoria you feel during sexual experiences - similar to a "runners high."
Muscles in the vagina, anus, and uterus contract and release - like a workout.
Not only is your pulse racing, but you may also be working out some of the muscles in your body (aside from the ones you're using to physically have sex).
According to Bustle, "Increased blood flow to the genitals during orgasm also maintains the integrity of the smooth muscle that lines the vagina, rectum and connective tissue between the penile shaft and scrotum."
Orgasms may improve allergy symptoms or clear blocked nasal passages.
"Orgasms can be effective at opening blocked nasal passages and can alleviate some allergy and congestion symptoms," according to sexologist and clinical professional counselor Dr. Laura Deitsch.
- A skeleton representing a man who was tossed face down into a ditch nearly 2,500 years ago with his hands bound in front of his hips was dug up during an excavation outside of London.
- The discovery was made during a high speed rail project that has been a bonanza for archaeology, as the area is home to more than 60 ancient sites along the planned route.
- An ornate grave of a high status individual from the Roman period and an ancient ceremonial circle were also discovered during the excavations.
An ancient skeleton of a man dating back to the Iron Age was uncovered outside of London last month, and though archaeologists aren't certain what the cause of death was, clues point to a murder most foul.
A skeleton representing a man who was tossed face down into a ditch nearly 2,500 years ago with his hands bound in front of his hips was dug up during a high speed rail excavation.
The positioning of the remains have led archaeologists to suspect that the man may have been a victim of an ancient murder or execution. Though any bindings have since decomposed, his hands were positioned together and pinned under his pelvis. There was also no sign of a grave or coffin.
"He seems to have had his hands tied, and he was face-down in the bottom of the ditch," said archaeologist Rachel Wood, who led the excavation. "There are not many ways that you end up that way."
Currently, archaeologists are examining the skeleton to uncover more information about the circumstances of the man's death. Fragments of pottery found in the ditch may offer some clues as to exactly when the man died.
"If he was struck across the head with a heavy object, you could find a mark of that on the back of the skull," Wood said to Live Science. "If he was stabbed, you could find blade marks on the ribs. So we're hoping to find something like that, to tell us how he died."
Other discoveries at Wellwick Farm
The grim discovery was made at Wellwick Farm near Wendover. That is about 15 miles north-west of the outskirts of London, where a tunnel is going to be built as part of a HS2 high-speed rail project due to open between London and several northern cities sometime after 2028. The infrastructure project has been something of a bonanza for archaeology as the area is home to more than 60 ancient sites along the planned route that are now being excavated before construction begins.
The farm sits less than a mile away from the ancient highway Icknield Way that runs along the tops of the Chiltern Hills. The route (now mostly trails) has been used since prehistoric times. Evidence at Wellwick Farm indicates that from the Neolithic to the Medieval eras, humans have occupied the region for more than 4,000 years, making it a rich area for archaeological finds.
Wood and her colleagues found some evidence of an ancient village occupied from the late Bronze Age (more than 3,000 years ago) until the Roman Empire's invasion of southern England about 2,000 years ago. At the site were the remains of animal pens, pits for disposing food, and a roundhouse — a standard British dwelling during the Bronze Age constructed with a circular plan made of stone or wood topped with a conical thatched roof.

While these ancient people moved away from Wellwick Farm before the Romans invaded, a large portion of the area was still used for ritual burials for high-status members of society, Wood told Live Science. The ceremonial burial site included a circular ditch (about 60 feet across) at the center, and was a bit of a distance away from the ditch where the (suspected) murder victim was uncovered. Additionally, archaeologists found an ornately detailed grave near the sacred burial site that dates back to the Roman period, hundreds of years later when the original Bronze Age burial site would have been overgrown.
The newer grave from the Roman period encapsulated an adult skeleton contained in a lead-lined coffin. It's likely that the outer coffin had been made of wood that rotted away. Since it was clearly an ornate burial, the occupant of the grave was probably a person of high status who could afford such a lavish burial. However, according to Wood, no treasures or tokens had been discovered.
Sacred timber circle

One of the most compelling archaeological discoveries at Wellwick Farm are the indications of a huge ceremonial circle once circumscribed by timber posts lying south of the Bronze Age burial site. Though the wooden posts have rotted away, signs of the post holes remain. It's thought to date from the Neolithic period to 5,000 years ago, according to Wood.
This circle would have had a diameter stretching 210 feet across and consisted of two rings of hundreds of posts. There would have been an entry gap to the south-west. Five posts in the very center of the circle aligned with that same gap, which, according to Wood, appeared to have been in the direction of the rising sun on the day of the midwinter solstice.
Similar Neolithic timber circles have been discovered around Great Britain, such as one near Stonehenge that is considered to date back to around the same time.
