Mama, Don't Let Your Babies Grow Up To Deny Evolution
If adults want to deny evolution, sure. That’s fine. Whatever. But those adults better not make their kids follow in step because we as society need them to be better. Bill Nye, everyone's favorite Science Guy, explains the importance of promoting evolution education for America's future voters and lawmakers.
My Man, Sir Isaac Newton
Are you at least 26 years-old? If so, you are older than Isaac Newton was when he invented calculus... on a dare! (If you're younger than 26, better hurry up.) Big Think expert and overall cool guy Neil deGrasse Tyson explains why Newton is the greatest physicist who ever and likely will ever live.
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.

Why I Came Out at Age 81
As a teenager in the '40s, James Randi "would have gotten stoned" for being gay. But when he outed himself to the world in 2010, the reaction was "wonderful."
America is experiencing some of its most widespread civil unrest in years following the death of George Floyd.
Floyd was killed in police custody in Minneapolis on 25 May, and his death has underscored the many ways race and ethnic background drives unequal experiences among many Americans.
These charts help illustrate key gaps impacting everything from opportunity to health.
1. Wide educational gaps
In the 70 years since the US Supreme Court ruled racial segregation of public schools unconstitutional, progress in improving racial educational divides has been slow and uneven. Gaps have narrowed by 30-40% when compared to the 1970s, but divides remain large.Improvement in 9-year-olds' NEAP math test scores (Image: Stanford Center for Education Policy Analysis)
2. Limited access to improved earnings, mobility
For people of colour in America, education does not provide the same economic return as it might for other groups. People of colour, particularly women of colour, typically have lower salaries than white and male workers with similar levels of education.Even with similar educational levels, wen of colour are still earning less. (Image: Equitable Growth)
Income inequality is also stifling intergenerational mobility – the American Dream of children having a higher standard of living than their parents. Research from economist Raj Chetty in 2016 showed that at age 30 people born in 1940 had around a 90% chance of out-earning their parents. But for people born in 1980 this chance had fallen to half.
3. Outsized unemployment burdens
A lack of access to higher education or skilled work can make people of colour more vulnerable to unemployment during downturns and periods of economic growth. As researchers explained in one report from The Russell Sage Foundation and The Stanford Center on Poverty and Inequality: "An African American cannot count on education as providing the same relief against the risk of unemployment that it provides to other groups."
4. Health care insurance and life expectancy dynamics
Life expectancy gaps between white Americans and people of colour have begun to narrow, but inequities still exist thanks to a range of socio-economic factors such as income inequality, access to health insurance and adequate health care.
The disproportionate impact that COVID-19 has had on black Americans demonstrates some of the vulnerabilities the population faces.
5. Black imprisonment in the US is falling but remains disproportionate
The imprisonment rate among black Americans has fallen by over a third since 2006, and stands at around 1,500 prisoners for every 100,000 adults. But black Americans remain far more likely to be in prison than Hispanic and white Americans. The figures are particularly stark among some age groups: in the 35-39 age bracket about 1 in 20 black men were in state or federal prison in 2018.

Black Americans made up a third of the sentenced prison population in 2018 – nearly triple their representation in the US adult population as a whole. They also make up a disproportionate number of fatal police shootings.
- Being outside of Earth's atmosphere while also being able to look down on the planet is both a challenge and a unique benefit for astronauts conducting important and innovative experiments aboard the International Space Station.
- NASA astrophysicist Michelle Thaller explains why one such project, known as NICER (Neutron star Interior Composition Explorer), is "one of the most amazing discoveries of the last year."
- Researchers used x-ray light data from NICER to map the surface of neutrons (the spinning remnants of dead stars 10-50 times the mass of our sun). Thaller explains how this data can be used to create a clock more accurate than any on Earth, as well as a GPS device that can be used anywhere in the galaxy.
- Cannabis and frankincense were discovered at the "holy of holies" shrine in Tel Arad, Israel.
- Both substances were mixed with animal dung to promote heating.
- This marks the first time cannabis has been found in the Kingdom of Judah.
In an extensive review of the history and pharmacology of psychedelics, American chemist David E. Nichols writes that this class of serotonergic hallucinogens "may be the oldest class of psychopharmacological agents known to man." Three thousand year old hymns to soma—a tea likely brewed with psilocybin mushrooms—are recorded in Vedic literature; the Eleusinian mysteries almost certainly involved a hallucinogenic brew.
Humans have been tripping for a long time.
This isn't surprising. Our ancestors undoubtedly tasted every plant and fungus available. If you're seeking food and stumble into a plant that breaks open the head (as the Bwiti describe the African rainforest shrub, iboga), you'll likely cultivate it. You might even create a ritual or two based on its consciousness-expanding qualities. Maybe a religion springs up devoted to plant life.
Indian scriptures point to cannabis as often as psilocybin. The god Indra loved drinking bhang, a milky beverage containing enough marijuana to make him trip. Shiva imbibed as well. The Vedas praise cannabis as a "divine nectar" that bestows long life and divine visions. Further north, Chinese Taoists combined cannabis with ginseng in a ceremony that helped monks portend the future. Herodotus praised cannabis steam baths built by the warrior clan, the Scythians.
As it turns out, Jews loved cannabis as well. An excavation at an Israeli shrine in Tel Arad has uncovered an altar filled with cannabis and frankincense. According to new research published in the journal, Tel Aviv, the "holy of holies" shrine dates back to 750-715 BCE. As the researchers—Eran Arie, Baruch Rosen, and Dvory Namdar—write, the ritual usage appears to be hallucinogenic.
A black, resinous substance was discovered on two small altars. On one of them, a laboratory analysis found residues of tetrahydrocannabinol (THC), cannabidiol (CBD), and cannabinol (CBN). According to Arie, this marks the first time cannabis has been identified in the Ancient Near East. The article notes that another material was discovered in the resin.
"Organic residues attributed to animal dung were also found, suggesting that the cannabis resin had been mixed with dung to enable mild heating."
The frankincense altar also contained animal fat, which promotes evaporation. Both frankincense and cannabis were likely mixed with animal products to promote burning. The fragrant incense was inhaled—frankincense for its aroma, cannabis for its psychoactive properties.
Frankincense dates back to the 15th century BCE and has long been used ceremonially. In the Bible, this tree resin is as valuable as gold and precious stones. Frankincense is one of the earliest known commodities, dating back 6,000 years on the Arabian peninsula; it fetched a high price as it was traded around the ancient world. While the smell is pleasing it doesn't have the same effect on consciousness. Enter cannabis.
"As the terpenoids detected are not unique to cannabis and may be found abundantly in many other local plants, it is likely that the cannabis burnt on the altar was not imported for its smell or therapeutic virtues but for its mind-altering abilities, expressed only by heating."
The authors are aware of hallucinogenic rituals in neighboring lands. This is the first time cannabis has been discovered in the Kingdom of Judah, however. The evidence proves what fans of psychoactive pharmacology have long known: Breaking open the head is an ancient tradition, regardless of ethnicity or religious belief.
I've lived much of my life with anxiety and depression, including the negative feelings – shame and self-doubt – that seduced me into believing the stigma around mental illness: that people knew I wasn't good enough; that they would avoid me because I was different or unstable; and that I had to find a way to make them like me.
It took me some time – I'm a classic late bloomer – but just before I turned 60, I discovered that sharing my story by drawing could be an effective way to both alleviate my symptoms and combat that stigma.
Mental health disorders are complicated. There are 22 sections of criteria and codes in the Diagnostic and Statistical Manual of Mental Disorders – and that's just for anxiety. Meanwhile, the psychiatric literature on depression is enormous, with hundreds of scholarly articles and books published in the past two years alone.
One thing we seem to know for certain is that, somehow, anxiety and depression made it through the evolutionary process.
“Since antiquity," writes William Styron in “Darkness Made Visible: A Memoir of Madness," “in the tortured lament of Job, in the choruses of Sophocles and Aeschylus – chroniclers of the human spirit have been wrestling with a vocabulary that might give proper expression to the desolation of melancholia."
My first anxiety attacks happened early in life. By the time I was 13, I knew the signs: quickened breathing and an increased heart rate, blurry vision, sweaty palms, and sudden fight or flight impulses. Once, when on deck to bat in Little League, I became so panicked I dropped my bat and fled the ball field. I rode my bike all the way home, barely able to see five feet in front of me.
Growing up, I also spent countless hours drawing. I drew or scribbled on every scrap of paper I could find, and I copied those funny characters that appeared on the back of each week's issue of TV Guide. While I took one art class in high school, I was mostly self-taught. I always knew I loved to draw, but I never wondered why. It was just something I did.
As I grew older, I continued to suffer from panic attacks and depressive episodes, which I managed to hide from others. I eventually became a theater professor at Penn State University, where I still teach today. In addition to teaching history and literature, I make autobiographical solo performance pieces. But in 2014, my sister died after spending two years in a vegetative state due to a traumatic brain injury. It was as if the one thread capable of unraveling my entire life was pulled.
Drawing became almost an obsession.

I did over 200 drawings of my sister and eventually created a play and solo performance piece titled “Drifting." I visually archived her journey to death. In the midst of this, I started what became the Anxiety Project, which now contains over 500 drawings and two performance pieces. I didn't really think too much about its purpose. I just knew I had to make drawings about anxiety and depression.
I made a lot of this work without any initial plans to share it. I was just trying to survive. As I slowly began to share some of the work, there was a strange mix of relief from sharing my feelings and dread that the work would ultimately fail to mean anything to others, or that people would think I was crazy for making this kind of work. (These same feelings have cropped up while writing this article.)
And then I pretty much crashed. I still couldn't emerge from my grief or separate it from my ongoing struggles with anxiety and depression.

I was in trouble. And I knew I had to get help. So I started to tell my wife and family the truth – that this struggle went beyond the death of my sister, that for most of my life, I had been in an almost constant battle with anxiety and depression, and that I was afraid I was finally losing and might go crazy. I found an excellent therapist. I started doing the hard work of living with my anxiety and depression honestly and openly, which, for me, includes taking an antidepressant. Acknowledging and accepting the need for medication was perhaps the most difficult stigma to face. I felt like a failure. Getting past that feeling took some time.

Living openly with my anxiety and depression has helped me better understand my drawing and creative work as efforts to make meaning out of the volcanic feelings of fear and despair – and the almost catatonic shutdowns that could happen inside me at any time.
This new understanding eventually led me to become intentional about drawing as a way to imagine myself as mentally healthy, rather than define myself by my mental illness. I drew upon the work of artists like Frederick Franck and his books “The Zen of Seeing" and “The Awakened Eye," which outline simple meditative approaches to drawing.
I work almost solely in ink- and water-based mediums because of the gestural and fluid ways I can translate feelings into lines and movement of color. I draw every day, and sometimes I'll simply draw what I see – birds, flowers, landscapes, people, myself – to stay grounded in the here and now.

Sharing what it's like to live with anxiety and depression feels like undressing in front of strangers, but I thought it might help decrease stigma, which nearly 90% of people with mental health problems say has a negative effect on their lives.
As I learned more about the connection between drawing, wellness and stigma, it turns out that I was onto something.
In 2016, psychologist Jennifer Drake and her team of researchers studied the benefits of drawing over four consecutive days, and discovered that the simple daily act has benefits. “You can get a positive effect with just 15 minutes of drawing," she concludes. “Drawing to distract is a simple and powerful way to elevate mood, at least in the short term." Meanwhile, researchers across many scientific fields have explored the ways art making can combat stigma about mental illness.
As Jenny Lawson writes in “Furiously Happy: A Funny Book About Horrible Things," “When you come out of the grips of a depression there is an incredible relief, but not one you feel allowed to celebrate. Instead, the feeling of victory is replaced with anxiety that it will happen again, and with shame and vulnerability when you see how your illness affected your family, your work, everything left untouched while you struggled to survive."
For me, it was the kind of shame that shepherds you right into the waiting arms of the stigma around mental illness. I needed to find a way through – for myself and, hopefully, for others.
Art became the way.
- A joint study by the universities of Coventry and Oxford in England has linked sexual activity with higher cognitive abilities in older age.
- The results of this study suggest there are significant associations between sexual activity and number sequencing/word recall in men. In women, however, there was a significant association between sexual activity in word recall alone - number sequencing was not impacted.
- The differences in testosterone (the male sex hormone) and oxytocin (a predominantly female hormone) may factor into why the male cognitive level changes much more during sexual activity in older age.
Countless studies have been done on the health benefits of sex - from an orgasm giving you clearer skin and a boosted immune system, to the physical activity keeping your blood pressure at a healthy level. A lowered risk of heart disease, the ability to block pain, a lowered risk of prostate cancer, less stress which leads to improved sleeping patterns...all of these are proven benefits of sexual activity.
The health benefits of sex have been studied again and again, and yet, there are still new things we're learning about the benefits on the human body and brain.
Study links sexual activity to higher cognitive function in old age
The results of this study suggest there are significant associations between sexual activity and number sequencing/word recall in men and a significant association between sexual activity in word recall in women.

Cognitive function has been associated with various physical, psychological, and emotional patterns in older adults - from lifestyle to quality of life, loneliness, and mood changes as well as physical activity levels.
A 2016 joint study by the universities of Coventry and Oxford in England has linked sexual activity with higher/better cognitive abilities in older age.
This longitudinal study used a newly available wave of data from the English Longitudinal Study of Ageing to explore the connections between sexual activity in the older population (50+) with cognitive function.
The study consisted of 6,833 participants between the ages of 50-89 years old.
Two different cognitive function tests were analyzed:
- Number sequencing, which broadly relates to the brain's executive functions.
- Word recall, which relates to the brain's memory functions.
The results of these tests were then adjusted to account for each person's gender, age, education level, wealth, physical activity, and mental health. The reason for this is that the researchers noticed there are often biases in other studies that examine the links between sexual activity and overall health.
For example, in this scenario, without taking those things into account, healthy older Italian men with a continued interest in sex would score higher on these tests. Women, who are more likely to become widowed and lose their sexual partner, would score lower.
While studying the impact of sexual activity on overall health, there are not many studies that focus on the link between sexual activity and cognitive function, and no other study that focuses on sexual activity and cognitive function in older adults.
The results of this one-of-a-kind study suggest there are significant associations between sexual activity and number sequencing/word recall in men. In women, however, there was a significant association between sexual activity in word recall alone - number sequencing was not impacted.
You can see the breakdown of this information here.
Why were the results for males and females so different?
One of the highlights of this study was exploring the differences sexual activity has in cognitive function in older males and older females.

Exploring the differences when it comes to the improved cognitive ability between the older males and the older females in this study was one of the highlights of the research.
Testosterone versus oxytocin
Testosterone, which is the male sex hormone, reacts very differently to the brain than oxytocin, which is released in females during sexual activity.
Testosterone plays a key role in many different areas such as muscle mass, facial and pubic hair development, and mood changes. It also impacts your sex drive and your verbal memory and thinking ability.
Testosterone belongs to a class of male hormones, and although the ovaries of a woman do produce minimal amounts of testosterone, it's not enough to compare the impacts on the male and female bodies.
Oxytocin, on the other hand, is produced in the male and female bodies quite similarly, but ultimately the hormone reacts differently in the female body, triggering the portion of the brain responsible for emotion, motivation, and reward.
These differences in testosterone and oxytocin may factor into why the male cognitive level changes much more during sexual activity in older age.
Women's ability for memory recall remains a mystery…
Another study, this time back in 1997, looked at the relationship between gender and episodic memory. The results of this study proved that women have a higher level of performance on episodic memory tasks (for example, recalling childhood memories) than men. The reason for this was not further explored in this study and has remained something of a mystery, even now.
The female brain deteriorates during menopause.
Women very commonly struggle with memory-related problems during and post-menopause. This could be the reason why the original study proved older men had a higher cognitive ability in number sequencing than older women.
Along with menopause-related cognitive decline, women are also at a higher risk for memory impairment and dementia compared to men.
Lead researcher of the original 2016 study, Dr. Hayley Wright, from Coventry University, explains:
"Every time we do another piece of research we are getting a little bit closer to understanding why this association exists at all, what the underlying mechanisms are and whether there is a 'cause and effect' relationship between sexual activity and cognitive function in older people."
