This DIY toy is fun and simple — and could help tackle malaria and other diseases.

If you're, say, researching a new drug or vaccine, this lab might be perfect.

But not everyone is lucky enough to have access to such resources. If you're not in a big city, for example, or if you're one of the world's many remote health care workers, in which case you might be going someplace where you can bring only what fits in your Jeep.


Which means that lab is just not coming along.

One of the tools we'd really like to make "back-of-Jeep" friendly is the centrifuge.

Centrifuges are one of the most common scientific tools and work by spinning samples at ridiculously high speeds. In medicine they're used to prep blood samples for analysis. Unfortunately, typical centrifuges are bulky, heavy, expensive, and electronic, which led designers to search for alternative solutions.

Designers often look for inspiration in everyday objects. Some have tried salad spinners as a centrifuge replacement. Others tried egg beaters. Both of those were too slow and awkward, but now researchers at Stanford might have found something awesome.

This simple toy is known as a whirligig.

You may have played with one before, and if you haven't, they're dead simple to make. Researchers spotted it and were curious: Could this thing work as a centrifuge? It certainly spun, but how fast? The researchers decided to build their own prototype and test it out.

Using a high-speed camera and some seriously impressive physics calculations, they found that a whirligig could get up to a blisteringly fast 125,000 revolutions per minute. That's not just fast, that's centrifuge fast.

Since the first test, researchers have come up with a new whirligig design that could hold small amounts of blood or other scientific samples. They're calling it the "paperfuge" and are working with health care workers in Madagascar to learn how to improve and distribute it.

Initial results seem good. They can get blood samples to separate in just 90 seconds. After 15 minutes, results were fine enough to even identify malaria parasites. This means the paperfuge might be able to bring a ton of new tests — from basic health checkups to serious diagnostics — to the millions of people who live outside the range of typical labs.

A lot of science is, unfortunately, out of reach for normal people. Clever design like this could remove some of the barriers.

Creating more accessible equipment could help democratize science, says Dr. Manu Prakash, one of the researchers who worked on the paperfuge. There are a ton of smart, knowledgable people out there, but living in a place where you can easily get and use thousand-dollar centrifuges is a privilege many do not get. New tools like the paperfuge could change that.

Science is one of the best ways we have to learn about and change our world. Imagine what we can do once everyone has access to it.

With the COVID-19 pandemic upending her community, Brooklyn-based singer Tiffany Obi turned to healing those who had lost loved ones the way she knew best — through music.

Obi quickly ran into one glaring issue as she began performing solo at memorials. Many of the venues where she performed didn't have the proper equipment for her to play a recorded song to accompany her singing. Often called on to perform the day before a service, Obi couldn't find any pianists to play with her on such short notice.

As she looked at the empty piano at a recent performance, Obi's had a revelation.

"Music just makes everything better," Obi said. "If there was an app to bring musicians together on short notice, we could bring so much joy to the people at those memorials."

Using the coding skills she gained at Pursuit — a rigorous, four-year intensive program that trains adults from underserved backgrounds and no prior experience in programming — Obi turned this market gap into the very first app she created.

She worked alongside four other Pursuit Fellows to build In Tune, an app that connects musicians in close proximity to foster opportunities for collaboration.

When she learned about and applied to Pursuit, Obi was eager to be a part of Pursuit's vision to empower their Fellows to build successful careers in tech. Pursuit's Fellows are representative of the community they want to build: 50% women, 70% Black or Latinx, 40% immigrant, 60% non-Bachelor's degree holders, and more than 50% are public assistance recipients.

Yesterday I was perusing comments on an Upworthy article about Joe Biden comforting the son of a Parkland shooting victim and immediately had flashbacks to the lead-up of the 2016 election. In describing former vice President Biden, some commenters were using the words "criminal," "corrupt," and "pedophile—exactly the same words people used to describe Hillary Clinton in 2016.

I remember being baffled that so many people were so convinced of Clinton's evil schemes that they genuinely saw the documented serial liar and cheat that she was running against as the lesser of two evils. I mean, sure, if you believe that a career politician had spent years being paid off by powerful people and was trafficking children to suck their blood in her free time, just about anything looks like a better alternative.

But none of that was true.

It's been four years and Hillary Clinton has been found guilty of exactly none of the criminal activity she was being accused of. Trump spent every campaign rally leading chants of "Lock her up!" under the guise that she was going to go to jail after the election. He's been president for nearly four years now, and where is Clinton? Not in jail—she's comfy at home, occasionally trolling Trump on Twitter and doing podcasts.

Glenda moved to Houston from Ohio just before the pandemic hit. She didn't know that COVID-19-related delays would make it difficult to get her Texas driver's license and apply for unemployment benefits. She quickly found herself in an impossible situation — stranded in a strange place without money for food, gas, or a job to provide what she needed.

Alone, hungry, and scared, Glenda dialed 2-1-1 for help. The person on the other end of the line directed her to the Houston-based nonprofit Bread of Life, founded by St. John's United Methodist pastors Rudy and Juanita Rasmus.

For nearly 30 years, Bread of Life has been at the forefront of HIV/AIDS prevention, eliminating food insecurity, providing permanent housing to formerly homeless individuals and disaster relief.

Glenda sat in her car for 20 minutes outside of the building, trying to muster up the courage to get out and ask for help. She'd never been in this situation before, and she was terrified.

When she finally got out, she encountered Eva Thibaudeau, who happened to be walking down the street at the exact same time. Thibaudeau is the CEO of Temenos CDC, a nonprofit multi-unit housing development also founded by the Rasmuses, with a mission to serve Midtown Houston's homeless population.

Empathy. Compassion. Heart-to-heart human connection. These qualities of leadership may not be flashy or loud, but they speak volumes when we see them in action.

A clip of Joe Biden is going viral because it reminds us what that kind of leadership looks like. The video shows a key moment at a memorial service for Chris Hixon, the athletic director at Marjory Stoneman Douglas High School in Parkland, Florida in 2018. Hixon had attempted to disarm the gunman who went on a shooting spree at the school, killing 17 people—including Hixon—and injuring 17 more.

Biden asked who Hixon's parents were as the clip begins, and is directed to his right. Hixon's wife introduces herself, and Biden says, "God love you." As he starts to walk away, a voice off-camera says something and Biden immediately turns around. The voice came from Hixon's son, Corey, and the moments that followed are what have people feeling all their feelings.

Founded by Lauren Singer, otherwise known as, "the girl with the jar" (she initially went viral for fitting 8 years of all of the waste she's created in one mason jar). Package Free is an ecosystem of brands on a mission to make the world less trashy.

Here are eight of our favorite everyday swaps:

1. Friendsheep Dryer Balls - Replace traditional dryer sheets with these dryer balls that are made without chemicals and conserve energy. Not only do these also reduce dry time by 20% but they're so cute and come in an assortment of patterns!

Package Free Shop

2. Last Swab - Replacement for single use plastic cotton swabs. Nearly 25.5 billion single use swabs are produced and discarded every year in the U.S., but not this one. It lasts up to 1,000 uses as it's able to be cleaned with soap and water. It also comes in a biodegradable, corn based case so you can use it on the go!
