Breakthrough study offers ray of hope to those suffering from anxiety.

Neuroscientists just pinpointed the physical source of anxiety in our brains — and it could lead to a breakthrough treatment.

Using mice. And light rays.

Experiments have located so-called "anxiety cells" located in the hippocampus of mice brains. Using a ray of light, researchers found they could literally turn down the level of anxiety in these cells.


“This is exciting because it represents a direct, rapid pathway in the brain that lets animals respond to anxiety-provoking places without needing to go through higher-order brain regions,” said Mazen Kheirbek, assistant professor of psychiatry at University of California, San Francisco, and a lead investigator on the joint study conducted by UCSF and Columbia University.

Nearly 1 in 5 Americans has experienced an anxiety disorder.

According to the National Institute of Mental Health, an estimated 31% of U.S. adults will experience an anxiety disorder in at some point in their lives.

And celebrities are not immune either. Public figures like Kristen Bell, Lady Gaga, and journalist Dan Harris have shared their own difficulties in navigating a mental illness that can seem invisible to everyone else.

The most common treatments typically involve a combination of therapy and medications. Antidepressents, or SSRI drugs, have come under increased scrutiny in recent years, with critics arguing they are often over-prescribed and in less severe cases may even mask symptoms that could be otherwise treated through different approaches.

A ray of hope. Seriously.

That's what makes this new study so compelling. If there's an alternative approach to treating anxiety that is both more precise and less invasive, it could be a legitimate breakthrough approach to treating anxiety disorders.

Using rays of light, the researchers were able to track the brain activity in freely moving mice, getting real-time feedback about whether the "anxiety neurons" in their brains were activated during stressful situations:

"They found that suppressing the anxiety neuron pathway made animals more comfortable spending time in environments that usually frighten them, while stimulating the same neural connections made mice behave with anxiety even in safely enclosed spaces."

"Now that we’ve found these cells in the hippocampus, it opens up new areas for exploring treatment ideas that we didn’t know existed before," said Jessica Jimenez, lead author of the joint study.

There's still a lot more work to be done.

Even though the study offers a ton of potential, experiments on mice don't always perfectly translate to trials on humans.

Even though he calls the initial results "tremendous progress," NIMH director Joshua Gordon said we're still far from a solution. "You can think of this paper as one brick in a big wall," he told NPR.

Still, there's no denying the promise and potential for the millions of people living with anxiety disorders and the countless others affected by such challenges.

The gaze of the approving Boomer.

Over the past few years, Baby Boomers (1946 to 1964) have been getting a lot of grief from the generations that came after them, Gen X (1965 to 1980), Millenials (1981 to 1996), and now, Gen Z (1997 to 2012). Their grievances include environmental destruction, wealth hoarding, political polarization, and being judgemental when they don’t understand how hard it is for younger people to make it in America these days.

Every Baby Boomer is different, so it's wrong to paint them all with a broad brush. But it’s undeniable that each generation shares common values, and some are bound to come into conflict.

However, life in 2023 isn’t without its annoyances. Many that came about after the technological revolution put a phone in everyone’s hands and brought a whole new host of problems. Add the younger generations' hands-on approach to child rearing and penchant for outrage, and a lot of moden life has become insufferanble.

Tia Savva has an invested father.

Sadly, a lot of men go out of their way to avoid learning anything about a woman's period.

(That could be why throughout most of the United States — where the majority of lawmakers are men — feminine hygiene products are subject to sales tax.)

So we should give some love to the guys who make an effort to learn a bit about the menstrual cycle so they can help their family members when they're in desperate need of feminine hygiene products.

Personally, as a guy, the feminine hygiene aisle can be a little intimidating. There are multiple brands, styles of products, scents, absorbency levels, and they are all color-coded.

What do the colors mean?

Prepare to get Thatcherized.

It seems that Adele is going viral once again.

Perhaps you’ve seen the image in question previously (it seems to make the rounds every couple of years). But in case you missed it—it’s Adele’s face. Normal, just upside down.

Only it’s not normal. In fact, when you turn Adele’s face right side up, what you notice is that her eyes and mouth were actually right-side up THE ENTIRE TIME, even though the entire head was upside down. So when you turn the head right side up, the eyes and mouth are now UPSIDE-DOWN—and you can’t unsee it. Do you feel like you're Alice in Wonderland yet?

Non-Americans are sharing the ‘dead giveaway’ someone is American and they are pretty right

The dead giveaway is when they call me "honey" or "sweetie" or "darling."

Three American tourists enjoying the sights.

One of the most interesting things about traveling the world is noticing how people from your country are a bit different from the place you’re visiting. In America, you’re mostly around fellow countrymen so it’s hard to notice the things that make us stand out.

But when you travel abroad, you quickly notice that no matter how hard you try to blend in, there are a lot of dead giveaways that show people you’re from the states that go way beyond your accent.

Doctor's alcohol tip that 'could save your life' goes viral on TikTok

Something to keep in mind for holiday parties and beyond.

A doctor's take on drinking at parties

New Year’s Eve is often a night filled with celebratory shots and champagne toasts. But as the party night fast approaches, one doctor is gently reminding folks the importance of partying responsibly during the holidays. Really, it’s a piece of advice that’s important all year long.

Dr. Brian Hoeflinger, an Ohio based neurosurgeon with over two decades of experience, has a TikTok channel filled with educational videos and lifestyle tips. But it’s his latest clip explaining just how long it takes our bodies to break down alcohol that has gone viral.

In the video, which was shared on Christmas Day, Dr. Hoeflinger sets the scene of a party where “a lot of drinks are going down” by setting up a bunch of shot glasses filled with water.

“Say you’re having five drinks in the first hour,” he says, taking five fake, water-filled shots. “As you’re taking them, that alcohol is building up in your system fast. [It] goes to your brain within five minutes and starts to affect you."

Mom's reaction to toddler's self haircut

An unsupervised toddler with a pair of scissors is nightmare fuel for parents.

Will you find shredded books, a hole in your new couch, or a pile of lopped off hair when you emerge from your quick trip to the potty?

Toddlers may still be very young, but they are fast and have a knack for getting ahold of unapproved things quickly, inflicting maximum destruction. TikTok user, @designerluxury4you, shared a video of their toddler proudly showing off the haircut she had given herself.

Experiencing your child giving themselves or their siblings a haircut seems to be a rite of passage for parents.

But the way this mom handled the discovery is showing how gentle parenting is changing the game. It's pretty safe to say that most parents would react in a more expressive way and immediately remove the scissors from the child's hands. This mom responded in the kindest and most respectful way you can imagine and maybe the internet is a little better for having seen it.
