What does a Hamburger Grown from Stem Cells Taste Like?

By Chris Gayomali

Two years ago, Mark Post of Maastricht University in the Netherlands set out to create a hamburger synthetically grown in a lab. That meant no actual cows, no bloody slaughterhouses, and just a fraction of the carbon emissions associated with cattle raising.

Today in London, the fruits of Post's laborious quest were finally put to the test, as the $330,000 petri-dish patty was tasted by food writer Josh Schonwald and Austrian food researcher Hanni Rutzler in front of a room full of reporters. The final verdict?

"There is quite some intense flavor," said Rutzler. "The look was quite similar to meat. It has quite a bite." Rutlzer continued:

The surface of the meat was crunchy—surprisingly. The taste itself was as juicy as meat can be, but different. It tastes like meat, not a meat-substitute like soya or whatever. [NBC News]

Schonwald was somewhat less effusive. "There is a leanness to it," he said. "The absence of fat is what makes it taste different… I would say it is somewhere on the spectrum between a Boca Burger [soy burger brand] and McDonald's."

Monday's tasting mixed the lab-grown meat with salt, egg, bread crumbs, as well as red beet juice and saffron to give the patty a more natural, reddish coloring. It was then fried in a pan and lightly seasoned with salt and pepper.

Assembling the faux meat-patty was no easy task. Once the stem cells were extracted from a living cow via biopsy, thin slivers were meticulously arranged—layer by layer—to form the genesis of actual cow muscle tissue. Post says it takes about 20,000 tiny slivers just to create one 5-ounce hamburger.

While lab-grown meat is still a long way from commercial viability, Post says that eventually, one stem-cell sample could be used to create up to 20,000 tons of beef. And remember, cattle raising takes a tremendous ecological toll on the environment, and is largely considered to be unsustainable.

A 2006 United Nations report, for example, revealed that the meat industry generates "more global-warming greenhouse gases, as measured in CO2 equivalent, than transportation." And yes, a hulking percentage of the environmental the damage is wrought from what's emitted out of cows' butts:

When emissions from land use and land use change are included, the livestock sector accounts for 9 percent of CO2 deriving from human-related activities, but produces a much larger share of even more harmful greenhouse gases. It generates 65 percent of human-related nitrous oxide, which has 296 times the Global Warming Potential (GWP) of CO2. Most of this comes from manure.

And it accounts for respectively 37 percent of all human-induced methane (23 times as warming as CO2), which is largely produced by the digestive system of ruminants, and 64 percent of ammonia, which contributes significantly to acid rain. [UN.org]

Post's project was funded largely by one mystery donor, who has remained in the dark — until now. On Monday, the project's backer was revealed to be none other than Google co-founder and Glass-futurist Sergey Brin. "If it succeeds there, it can be really transformative for the world," Brin told the Guardian. "If what you're doing is not seen by some people as science fiction, it's probably not transformative enough."

So: Would you give lab-grown hamburger meat a try? Let us know below.

The Sweet Surprise Reunion Mr. Rogers Never Saw Coming

Family Communications Inc./Getty Images

For more than 30 years, legendary children’s show host Fred Rogers used his PBS series Mister Rogers’ Neighborhood to educate his young viewers on concepts like empathy, sharing, and grief. As a result, he won just about every television award he was eligible for, some of them many times over.

Rogers was gracious in accepting each, but according to those who were close to the host, one honor in particular stood out. It was March 11, 1999, and Rogers was being inducted into the Television Academy Hall of Fame, an offshoot of the Emmy Awards. Just before being called to the stage, out came a surprise.

The man responsible for the elation on Rogers’s face was Jeff Erlanger, a 29-year-old from Madison, Wisconsin who became a quadriplegic at a young age after undergoing spinal surgery to remove a tumor. Rogers was surprised because Erlanger had appeared on his show nearly 20 years prior in 1980 to help kids understand how people with physical challenges adapt to life’s challenges. Here's his first encounter with the host:

Reunited on stage after two decades, Erlanger referred to the song, “It’s You I Like,” which the two sang during their initial meeting. “On behalf of millions of children and grown-ups,” Erlanger said, “it’s you I like.” The audience, including a visibly moved Candice Bergen, rose to their feet to give both men a standing ovation.

Following Erlanger’s death in 2007, Hedda Sharapan, an employee with Rogers’s production company, called their poignant scene “authentic” and “unscripted,” and that Rogers often pointed to it as his favorite moment from the series.

Near the end of the original segment in 1980, as Erlanger drives his wheelchair off-camera, Rogers waves goodbye and offers a departing message: “I hope you’ll come back to visit again.”

20 Things You Might Not Have Known About Firefly

As any diehard fan will be quick to tell you, Firefly's run was far, far too short. Despite its truncated run, the show still offers a wealth of fun facts and hidden Easter eggs. On the 15th anniversary of the series' premiere, we're looking back at the sci-fi series that kickstarted a Browncoat revolution.

1. A CIVIL WAR NOVEL INSPIRED THE FIREFLY UNIVERSE.

The Pulitzer Prize-winning novel The Killer Angels from author Michael Shaara was Joss Whedon’s inspiration for creating Firefly. It follows Union and Confederate soldiers during four days at the Battle of Gettysburg during the American Civil War. Whedon modeled the series and world on the Reconstruction Era, but set in the future.

2. ORIGINALLY, THE SERENITY CREW INCLUDED JUST FIVE MEMBERS.

When Whedon first developed Firefly, he wanted Serenity to only have five crew members. However, throughout development and casting, Whedon increased the cast from five to nine.

3. REBECCA GAYHEART WAS ORIGINALLY CAST TO PLAY INARA.

Before Morena Baccarin was cast as Inara Serra, Rebecca Gayheart landed the role—but she was fired after one day of shooting because she lacked chemistry with the rest of the cast. Baccarin was cast two days later and started shooting that day.

4. NEIL PATRICK HARRIS WAS ALMOST DR. SIMON TAM.

Before it went to Sean Maher, Neil Patrick Harris auditioned for the role of Dr. Simon Tam.

5. JOSS WHEDON WROTE THE THEME SONG.

Whedon wrote the lyrics and music for Firefly’s opening theme song, “The Ballad of Serenity.”

6. STAR WARS SPACECRAFT APPEAR IN FIREFLY.

Star Wars was a big influence on Whedon. Captain Malcolm Reynolds somewhat resembles Han Solo, while Whedon used the Millennium Falcon as inspiration to create Serenity. In fact, you can spot a few spacecraft from George Lucas's magnum opus on the show.

When Inara’s shuttle docks with Serenity in the pilot episode, an Imperial Shuttle can be found flying in the background. In the episode “Shindig,” you can see a Starlight Intruder as the crew lands on the planet Persephone.

7. HAN SOLO FROZEN IN CARBONITE POPS UP THROUGHOUT FIREFLY.

Nathan Fillion is a big Han Solo fan, so the Firefly prop department made a 12-inch replica of Han Solo encased in Carbonite for the Canadian-born actor. You can see the prop in the background in a number of scenes.

8. ALIEN'S WEYLAND-YUTANI CORPORATION MADE AN APPEARANCE.

In Firefly’s pilot episode, the opening scene features the legendary Battle of Serenity Valley between the Browncoats and The Union of Allied Planets. Captain Malcolm Reynolds takes control of a cannon with a Weyland-Yutani logo inside of its display. Weyland-Yutani is the large conglomerate corporation in the Alien film franchise. (Whedon wrote Alien: Resurrection in 1997.)

9. ZAC EFRON'S ACTING DEBUT WAS ON FIREFLY.

A 13-year-old Zac Efron made his acting debut in the episode “Safe” in 2002. He played Young Simon in a flashback.

10. CAPTAIN MALCOLM REYNOLDS'S HORSE IS A WESTERN TROPE.

At its core, Firefly is a sci-fi western—and Malcolm Reynolds rides the same horse on every planet (it's named Fred).

11. FOX AIRED FIREFLY'S EPISODES OUT OF ORDER.

Fox didn’t feel Firefly’s two-hour pilot episode was strong enough to air as its first episode. Instead, “The Train Job” was broadcast first because it featured more action and excitement. The network continued to cherry-pick episodes based on broad appeal rather than story consistency, and eventually aired the pilot as the show’s final episode.

12. THE ALLIANCE'S ORIGINS ARE AMERICAN AND CHINESE.

The full name of The Alliance is The Anglo-Sino Alliance. Whedon envisioned The Alliance as a merger of American and Chinese government and corporate superpowers. The Union of Allied Planets’ flag is a blending of the American and Chinese national flags.

13. THE SERENITY LOUNGE SERVED AS AN ACTUAL LOUNGE.

Between set-ups and shots, the cast would hang out in the lounge on the Serenity set rather than trailers or green rooms.

14. INARA SERRA'S NAME IS MESOPOTAMIAN.

Inara Serra is named after the Mesopotamian Hittite goddess, the protector of all wild animals.

15. THE CHARACTERS SWORE (JUST NOT IN ENGLISH).

The Firefly universe is a mixture of American and Chinese culture, which made it easy for writers to get around censors by having characters swear in Chinese.

16. THE UNIFORMS ARE RECYCLED FROM STARSHIP TROOPERS.

The uniforms for Alliance officers and soldiers were the costumes from the 1997 science fiction film Starship Troopers. The same costumes were repurposed again for the Starship Troopers sequel.

17. "SUMMER!" MEANS SOMEONE MESSED UP.

Every time a cast member flubbed one of his or her lines, they would yell Summer Glau’s name. This was a running gag among the cast after Glau forgot her lines in the episode “Objects In Space.”

18. THE SERENITY SPACESHIP WAS BUILT TO SCALE.

The interior of Serenity was built entirely to scale; rooms and sections were completely contiguous. The ship’s interior was split into two stages, one for the upper deck and one for the lower. Whedon showed off the Firefly set in one long take to open the Serenity movie.

19. "THE MESSAGE" SHOULD HAVE BEEN THE SHOW'S FAREWELL.

Although “The Message” was the twelfth episode, it was the last episode filmed during Firefly’s short run. Composer Greg Edmonson wrote a piece of music for a funeral scene in the episode, which served as a final farewell to the show. Sadly, it was one of three episodes (the other two were “Trash” and “Heart of Gold”) that didn’t air during Firefly’s original broadcast run on Fox.

20. FIREFLY AND SERENITY WERE SENT TO THE INTERNATIONAL SPACE STATION.

American Astronaut Steven Ray Swanson is a big fan of Firefly, so when he was sent to the International Space Station for his first mission (STS-117) in 2007, he brought DVD copies of Firefly and its feature film Serenity aboard with him. The DVDs are now a permanent part of the space station’s library.
