The human body is made up of roughly 10 trillion cells. That’s a huge number, but it’s dwarfed by the 40 trillion or so bacterial cells that live on and inside the body.
In recent years, scientists have learned that our bacteria — known collectively as the microbiome — are intimately involved with many aspects of our health, including the robustness of our immune system and our risk of developing asthma and allergies. Now, new research suggests that the microbiome may also play a key role in neurological and psychological disorders.
“At a basic neuroscience level, all the key mechanisms of the brain have been shown to be regulated by the microbiome,” says John Cryan, a neuroscientist at University College Cork in Ireland.
As scientists investigate how the microbiome impacts our bodies and minds, some experts envision fundamental changes in the way doctors diagnose and treat disease.
“Someday soon, you and I will go into the doctor’s office, and the doctor will prescribe medicine that won’t be a chemical from a lab but may be live bacteria,” says Sarkis Mazmanian, a microbiologist at Caltech in Pasadena, California. “In addition to blood work, yearly physicals may include fecal samples to profile the microbiome,” tracking changes in bacteria to predict your risk for illness, sometimes long before symptoms appear.

What do Barbra Streisand, Ozzy Osbourne and Will.i.am have in common? Yes, they’re famous musicians — but they also process sound differently from most of us.
That’s the latest finding of a study that examines people with mild to moderate tinnitus, a hearing condition common among musicians that causes a ringing sound in the ears. (As a drummer for nearly two decades and a former member of a touring band, I’ve had tinnitus for five years. I know what it’s like to never live in complete silence.)
The research, published in the journal PLOS One, shows that people with tinnitus can habituate the bothersome sound, mentally condemning it to that neurological basement area where refrigerator hums and street traffic live.
But here’s the especially cool part: To counteract the ringing, your brain literally changes how it operates.
University of Illinois speech and hearing science professor Fatima Husain, leader of the study, had subjects with mild to moderate tinnitus listen to pleasant, unpleasant and neutral sounds (for example: laughter, pained screaming and a bottle opening).
Husain expected to find that people with tinnitus would be further irritated by negative sounds, like adding a fire alarm on top of a Meghan Trainor song. Instead, Husain found the negative sounds didn’t bother patients as much, because in their brains, the sounds took a different path. They were rerouted from a place of emotional processing to one of logical processing.

The cost of college, like the cost of everything else, is going up. In fact, in the past 10 years, the price of attending a university has risen by more than 25%. It’s so expensive that a lot of promising students don’t get to go and those who do often end up saddled with student loan debt. So the fact that Oakland University in Michigan sent emails to 5,500 students mistakenly awarding them hefty scholarships seems like a very cruel joke.
Students received a congratulatory email on January 4th, according to the New York Times. It read, “You worked hard and it paid off!” it read, and informed students that they would receive a $48,000 academic scholarship over the course of four years. That’s a $12,000 a year scholarship at a school where the in-state tuition is $13,934 per year, according to Oakland University’s website. That’s basically a full ride.
So, when those individuals got those emails, they were understandably overjoyed. They called their parents. They told their friends. Someone probably texted all their friends to plan a celebratory beer run. Several people probably cried. Two hours later, those same students were totally deflated when they got another email from the university. “CORRECTION,” read the subject line of the email that reportedly said, “Because you are not a recipient of the Platinum Presidential Scholar Award, this message was unfortunately sent to you in error.”
“When they sent that email, I was like ‘Wow, this is my escape, this is everything I’ve ever wanted,'” Charmaine, an 18-year-old in Farmington and an incoming freshman at Oakland University, told ABC. Brown had been applying for scholarships nonstop, so the email was a dream come true. And then it was a nightmare. “That’s a big mistake. That’s a very big mistake,” Brown told ABC. She and her mother are currently petitioning the university to honor the scholarships.

Note: The numbers have changed since this article was published.
The eight individuals who own as much as half of the rest of the planet are all men and have largely made their fortunes in technology. Most are American, with one European and one Mexican in the mix. Several have pledged to give it all to charity.
The eight tycoons’ net worth, as calculated by Forbes magazine, was cited Monday by anti-poverty activists Oxfam in a report highlighting income inequality. Although most of them will not be joining the annual meeting of business and political elites in the Swiss town of Davos this week, the extraordinary individual wealth they typify will be part of the gathering’s discussions on inequality.

The world is ticking another 30 seconds closer to the apocalypse — in part because of Donald Trump.
At least that’s the dire warning from the group of scientists who oversee the metaphorical Doomsday Clock, the hands of which were moved Thursday to two minutes and 30 seconds before midnight — the time that represents when a catastrophic nuclear event can annihilate the earth.
It’s the closest the clock has been to midnight since the Cold War of the 1950s.
The clock is revised annually, but remained at three minutes before midnight last year — the same as it was in 2015 — after positive global developments such as the Iran nuclear deal and the Paris climate agreement helped stave off a doomsday scenario.
But the Chicago-based Bulletin of the Atomic Scientists, a science journal which oversees the clock, said recent events prompted them to push the clock forward in 2017.
Those include a rise in strident nationalism worldwide, cyber threats, an “active and blatant disregarding” for factual science and President Trump’s comments on nuclear arms and climate change.

Having sex and getting high are two fun things to do separately — but they’re even more fun to do at the same time. There are real-deal psychological and physiological benefits of a quick toke — or nibble or spray — before climbing into bed.
If you’re in the right headspace for it, sex with a head full of cannabis is great. It’s been shown that cannabis can act as an aphrodisiac, strengthening orgasms in women and boosting libido. “Sometimes when couples smoke marijuana, they take more time to have a fuller sensual experience and slow down, which would allow more time for vasocongestion (blood flow to genitals) and myotonia (muscular tension),” sex therapist Ian Kerner previously told Mic. He said weed can cause couples to feel “relaxed, comfortable and sexy, [which may] lead to a higher quality of orgasm.”
It’s all in your head: When it comes to sex and biology, men tend to obsess over erectile dysfunction. Drugs like Viagra and Cialis can fix the physiological symptoms, but the root problem is often psychological: stress and anxiety. “The mentality for men is that they just need a pill and that will solve all the psychological issues, but that doesn’t work,” Dr. Jordan Tishler, a cannabis therapeutics physician for Inhale MD, told Mic. “Whatever the psychological causes of the dysfunction or inability to make intimate contact, women are more willing to discuss above-the-neck issues than men.”
Cannabis, unless taken in excessive doses, is known to help curb stress and anxiety. Why and how it affects the brain isn’t talked about as much.
Your body actually makes cannabinoids in a part of your brain and nervous system called the endocannabinoid system, which helps regulate our stress and anxiety levels. THC, marijuana’s champion psychoactive ingredient, is chemically similar to a brain chemical called anandamide — better known as our body’s natural marijuana — that makes us less anxious.

As racial unrest sweeps across major college campuses, and African-American students demand more equitable treatment, college administrators need look no farther than their own admissions offices to find one root of the problem.
The nation’s flagship public universities — large, taxpayer-funded institutions whose declared mission is to educate residents of their states — enroll far smaller proportions of black students than other colleges, and the number appears to be declining, according to federal records and college enrollment data analyzed by The Hechinger Report and The Huffington Post.
On average, just 5 percent of students at the nation’s flagship public universities are black. As recently as a decade ago, that figure was higher, although changing methods of counting racial categories makes a precise comparison difficult.
Even here at the University of Virginia, which prides itself on the diversity of its campus, just 8 percent of students are black. Just 5 percent are black Virginians, in a state where 22 percent of public high school graduates are African-American. (Low-income students are also underrepresented at top schools).

Scientists at the University of New South Wales in Australia have made a stellar and rare discovery: The closest habitable planet to Earth is located 14 light-years away, which is eight light-years closer than scientists previously thought. The discovery is the result of a study from UNSW researchers, who found the planet located as part of a cluster of three others, all of which orbit the red dwarf star Wolf 1061. The new world is more than four times the size of Earth; researchers have named it Wolf 1061c.
“It is a particularly exciting find because all three planets are of low enough mass to be potentially rocky and have a solid surface, and the middle planet, Wolf 1061c, sits within the ‘Goldilocks’ zone where it might be possible for liquid water – and maybe even life — to exist,” said the UNSW study’s lead researcher Duncan Wright. “It is fascinating to look out at the vastness of space and think a star so very close to us — a near neighbor — could host a habitable planet.”
Prior to UNSW scientists’ discovery, the closest known habitable planet to Earth was Gliese 667Cc, according to the study, and is a planet four and a half times the size of earth that orbits another red dwarf star located 22 light-years away.
“The close proximity of the planets around Wolf 1061 means there is a good chance these planets may pass across the face of the star,” said Rob Wittenmyer, a member of the study’s research team at UNSW. “If they do, then it may be possible to study the atmospheres of these planets in the future to see whether they would be conducive to life.”
