This Lab-Grown Perfume is Made From an Extinct Flower

Geneticists still haven't gotten around to turning ancient DNA into living dinosaurs, but a team of scientists has done something similar with extinct plant life. As IEEE Spectrum reports, Gingko Bioworks, a synthetic-biology company based in Boston, Massachusetts, has successfully concocted a perfume using floral scents that have been missing from nature for decades.

Taking a page out of Jurassic Park, the Gingko Bioworks scientists used old, damaged samples of organic material to reconstruct extinct DNA. Instead of mining caves for mosquitoes trapped in amber, they paid a visit to the Harvard University Herbaria, which houses millions of dried plant specimens. The plants they took samples from, which included the Falls-of-the-Ohio scurfpea, the Wynberg conebush, and the Hawaiian mountain hibiscus, all disappeared from the planet in the 19th and early 20th centuries.

To make perfume out of the lost plants, scientists had to reconstruct their terpenes, or the compounds responsible for odor. Using DNA from modern plants to fill in the gaps in the genetic code, the team was able to create 2000 gene variants from the extinct plant samples. Yeast cells were used to trigger gene expression, and mass-spectrometry machines helped identify terpene molecules in the expressed genes.

Once those molecules were analyzed, Gingko Bioworks sent the terpene profiles to an olfactory artist named Sissel Tolaas, who mixed the molecules into an appealing scent. The Hawaiian mountain hibiscus perfume, which Gingko unveiled at their meeting in Boston last week, has a "piney, earthy" aroma, according to IEEE Spectrum.

Gingko Bioworks is selling its resurrected Hawaiian mountain hibiscus scent as part of an art installation that will be traveling the world next year. The Centre Georges Pompidou in Paris and the Cooper Hewitt in New York City are the first two stops on the tour.

You Can Now Go Inside Chernobyl’s Reactor 4 Control Room

The eerie interior of Chernobyl’s Reactor 4 control room, the site of the devastating nuclear explosion in 1986, is now officially open to tourists—as long as they’re willing to don full hazmat suits before entering and undergo two radiology tests upon exiting.

Gizmodo reports that the structure, which emits 40,000 times more radiation than any natural environment, is encased in what's called the New Safe Confinement, a 32,000-ton structure that seals the space off from its surroundings. All things considered, it seems like a jolly jaunt to these ruins might be ill-advised—but radiology tests are par for the course when it comes to visiting the exclusion zone, and even tour guides have said that they don’t usually reach dangerous levels of radiation on an annual basis.

Though souvenir opportunists have made off with most of the plastic switches on the machinery, the control room still contains original diagrams and wiring; and, according to Ruptly, it’s also been covered with an adhesive substance that prevents dust from forming.

The newly public attraction is part of a concerted effort by the Ukrainian government to rebrand what has historically been considered an internationally shameful chapter of the country's past.

“We must give this territory of Chernobyl a new life,” Ukraine's president Volodymyr Zelensky said in July. “Chernobyl is a unique place on the planet where nature revives after a global man-made disaster, where there is a real 'ghost town.' We have to show this place to the world: scientists, ecologists, historians, tourists."

It’s also an attempt to capitalize upon the tourism boom born from HBO’s wildly successful miniseries Chernobyl, which prompted a 35 percent spike in travel to the exclusion zone earlier this year. Zelensky’s administration, in addition to declaring the zone an official tourist destination, has worked to renovate paths, establish safe entry points and guidelines for visitors, and abolish the photo ban.

Invasive Snakehead Fish That Can Breathe on Land Is Roaming Georgia

A fish recently found in Georgia has wildlife officials stirred up. In fact, they’re advising anyone who sees a northern snakehead to kill it on sight.

That death sentence might sound extreme, but there’s good reason for it. The northern snakehead, which can survive for brief periods on land and breathe air, is an invasive species in North America. With one specimen found in a privately owned pond in Gwinnett County, the state wants to take swift action to make certain the fish, which is native to East Asia, doesn’t continue to spread. Non-native species can upset local ecosystems by competing with native species for food and habitat.

The Georgia Department of Natural Resources’ Wildlife Resources Division is advising people who encounter the snakehead—a long, splotchy-brown fish that can reach 3 feet in length—to kill it and freeze it, then report the catch to the agency's fisheries office.

Wildlife authorities believe snakeheads wind up in non-native areas as a result of the aquarium trade or food industry. A snakehead was recently caught in southwestern Pennsylvania. The species has been spotted in 14 states.
