Photographing the path of light.
A new camera developed at MIT can photograph a trillion frames per second.
Compare that with a traditional movie camera which takes a mere 24. This new advancement in photographic technology has given scientists the ability to photograph the movement of the fastest thing in the Universe, light.
The actual event occurred in a nano second, but the camera has the ability to slow it down to twenty seconds.
The amazing camera.

For some perspective, according to New York Times writer, John Markoff, "If a bullet were tracked in the same fashion moving through the same fluid, the resulting movie would last three years."In the video below, you'll see experimental footage of light photons traveling 600-million-miles-per-hour through water.
It's impossible to directly record light so the camera takes millions of scans to recreate each image. The process has been called femto-photography and according to Andrea Velten, a researcher involved with the project, "There's nothing in the universe that looks fast to this camera."

Pency Lucero taking in the Northern Lights
Seeing the northern lights is a common bucket list adventure for many people. After all, it ticks a lot of boxes—being a dazzling light show, rich historical experience and scientific phenomenon all rolled into one. Plus there’s the uncertainty of it all, never quite knowing if you’ll witness a vivid streak of otherworldly colors dance across the sky…or simply see an oddly colored cloud. It’s nature’s slot machine, if you will.
Traveler and content creator Pency Lucero was willing to take that gamble. After thorough research, she stumbled upon an Airbnb in Rörbäck, Sweden with an actual picture of the northern lights shining above the cabin in the listing. With that kind of photo evidence, she felt good about her odds.
However, as soon as she landed, snow began falling so hard that the entire sky was “barely visible,” she told Upworthy. Martin, the Airbnb host, was nonetheless determined to do everything he could to ensure his guests got to see the spectacle, even offering to wake Lucero up in the middle of the night if he saw anything.
Then one night, the knock came.
In a video Lucero posted to TikTok, which now has over 12 million views, we hear Martin ushering her out to take a peek. Then we see Lucero’s face light up just before seeing the sky do the same.
“I thought it was a prank,” the onscreen text reads in the clip. “And then I see it….”

“I was mostly in awe of what this Earth is capable of,” Lucero recalled. “I never expected it to be THAT beautiful for the naked eye.” This is a hopeful sentiment against the widely accepted notion that the northern lights are often better looking in photos than they are in real life.
As Lucero asserted in a follow-up video, “Our video doesn’t do it justice at all…I would argue it’s even better for the naked eye.”

Others were quick to back Lucero with anecdotes of their own experience.
“It’s definitely possible to see it like in the pics. I saw it this winter in Norway, there was bright green, purple and so much movement.”
“They’re so much better in person, the way they dance and move around is insane and beautiful.”
Of course, if you ask Martin, who everyone agreed was the best host ever, seeing guest reactions of pure wonder and joy is even “better than the lights themselves.” But still, he can’t deny that there’s a breathtaking magic to it all. He shared with Upworthy that “Sometimes it feels like it will pull you up in the sky like you are in the middle of it. I wish everyone would have the chance to witness it.”

When it comes to tips for actually seeing the northern lights, Martin admits it still mostly comes down to being in the right place at the right time. Luckily, his Airbnb listing can help with that.
Nature has a great way of reminding us that beyond the distractions and distresses of modern life, there is sublime beauty waiting for the chance to capture our hearts.

Because who can keep up with which laundry settings is for which item, anyway?
Once upon a time, our only option for getting clothes clean was to get out a bucket of soapy water and start scrubbing. Nowadays, we use fancy machines that not only do the labor for us, but give us free reign to choose between endless water temperature, wash duration, and spin speed combinations.
Of course, here’s where the paradox of choice comes in. Suddenly you’re second guessing whether that lace item needs to use the “delicates” cycle, or the “hand wash” one, or what exactly merits a “permanent press” cycle. And now, you’re wishing for that bygone bucket just to take away the mental rigamarole.
Well, you’re in luck. Turns out there’s only one setting you actually need. At least according to one laundry expert.While appearing on HuffPost’s “Am I Doing It Wrong?” podcast, Patric Richardson, aka The Laundry Evangelist, said he swears by the “express” cycle, as “it’s long enough to get your clothes clean but it’s short enough not to cause any damage.”
Richardson’s reasoning is founded in research done while writing his book, “Laundry Love,” which showed that even the dirtiest items would be cleaned in the “express” cycle, aka the “quick wash” or “30 minute setting.”
Furthermore the laundry expert, who’s also the host of HGTV’s “Laundry Guy,” warned that longer wash settings only cause more wear and tear, plus use up more water and power, making express wash a much more sustainable choice.
Really, the multiple settings washing machines have more to do with people being creatures of habit, and less to do with efficiency, Richardson explained.
“All of those cycles [on the washing machine] exist because they used to exist,” he told co-hosts Raj Punjabi and Noah Michelson. “We didn’t have the technology in the fabric, in the machine, in the detergent [that we do now], and we needed those cycles. In the ’70s, you needed the ‘bulky bedding’ cycle and the ‘sanitary’ cycle ... it was a legit thing. You don’t need them anymore, but too many people want to buy a machine and they’re like, ‘My mom’s machine has “whitest whites.”’ If I could build a washing machine, it would just have one button — you’d just push it, and it’d be warm water and ‘express’ cycle and that’s it.”
When was the last time you washed you washing machine? "Never" is a valid answer.

According to Good Housekeeping, there are some things to keep in mind if you plan to go strictly express from now on.
For one thing, the outlet recommends only filling the machine halfway and using a half dose of liquid, not powder detergent, since express cycles use less water. Second, using the setting regularly can develop a “musty” smell, due to the constant low-temperature water causing a buildup of mold or bacteria. To prevent this, running an empty wash on a hot setting, sans the detergent, is recommended every few weeks, along with regularly scrubbing the detergent drawer and door seal.
Still, even with those additional caveats, it might be worth it just to knock out multiple washes in one day. Cause let’s be honest—a day of laundry and television binging sounds pretty great, doesn’t it?
