Biden Calls Larry Elder 'Clone of Trump' As He Stumps for Gavin Newsom on Recall Election Eve

  Biden Calls Larry Elder 'Clone of Trump' As He Stumps for Gavin Newsom on Recall Election Eve "The leading Republican running for governor is the closest thing to a Trump clone that I've ever seen in your state," President Joe Biden told California voters on Monday.Biden joined Newsom for a campaign stop in Long Beach on the eve of the recall election. The president told the crowd that "the eyes of the nation" focused on California and that the election's results would "reverberate" around the world. He then repeatedly compared Elder, a conservative talk radio host who would be the state's first Black governor if elected, to the former president who he defeated in the 2020 election.

Woolly mammoth cloning is not possible. After ten thousand years (at least) the DNA will no longer be complete. There are, however, other ways of bringing them back. Altering an elephant’ s DNA (in a fertilized egg), for instance. Still, there’ s some ethical questions that need to be considered. Elephants are emotionally complex creatures. I don’t think an elephant cow would react well to constantly being used as a concubine to produce possibly deformed elephant- mammoth hybrid calves. I guess they could try the test tube method, but they’d need to get an egg outside of the elephant first.

Is it? : maybe Scientists now say they've got enough blood and bone to bring an Ice Age icon kicking and stomping into the modern age. All thanks to a The idea, as Tanya Lewis writes for LiveScience, would be to implant a mammoth embryo into an elephant, which would then give birth to a very, very old baby. Keep in mind, if scientists are successful, the ancient behemoth won't look exactly like it once did. 'It will be a different mammoth to the one living 43,000 years ago, specially taking into account that there will be interbreeding with a female elephant," Khayrullin told the Siberian Times.

Messing with megafauna usually doesn’t work out for the human parties involved, whether it’s a fictional island theme park overrun by killer dinosaurs or it’s Florida, where, in 1992, Hurricane Andrew released scores of exotic species held as pets, resulting in invasive Burmese pythons living in over 1,000 square miles of the state.

Into this legacy steps a company called Colossal, which plans to “jumpstart nature’s ancestral heartbeat” by cloning and re-introducing thousands of wooly mammoths in Siberia. Led by Harvard Medical School biologist George Church, the plan is to edit mammoth hair and tendencies into elephant DNA and produce mammoth embryos within several years.

 like Harvard Genetics George Church with the help of a biotech company to revive the extinct wool hair mammoth The wool-haired collection represents the last stage of development of the huge extinct elephant style, the mammoth. Until 3,700 years, copies of this animal stutzed by the Eurasian and American steppes. The attention of the Harvard genetician George Church caused the mammoth for the first time at the 1964 World's Fair. Church was reused on a reconstruction of the hairy mammal, as he recently remembered an interview.

Cloning the Wooly Mammoth . Discussion in 'Off-Topic' started by The 777 Hoax, Mar 23, 2006. The panda' s original habitat (bamboo forests) perhaps ranged over all China south of the Yangtze, but today they are confined to a few National Reserves in Yunnan that still have the right conditions (for them). The rest of southern China is now farmland. So should we just go on and let them go extinct?

JAPAN – Scientists have cloned a wooly mammoth ! A Japanese scientist has successfully cloned a real, actual woolly mammoth ! The last attempts at cloning mammoths were unsuccessful because the existing mammoth cells were too messed up by the millions of years of freezing cold. But Ikaki’ s new technique was first successful in cloning a mouse from frozen tissue, then an African elephant and now a mammoth .

There are potential benefits for the larger state of the world, if they can pull it off. Some researchers suggest that wooly mammoths helped transformed the now-mossy tundra into a fertilized grassland; if the Frankenstein version were able to achieve this feat again, the tundra could serve as a buffer against erosion and a potential carbon-dioxide sink to combat global warming. Colossal, which describes itself as “the de-extinction company,” also hopes the reanimation of the wooly mammoth could serve as a first step toward further genetic alterations to save endangered species on a planet threatened by biodiversity collapse by rewriting their DNA to allow them to adapt to a changing climate.

But as the New York Times notes, there’s some obvious concerns with the ambitious venture:

Joe Biden Jokingly Makes Sign of the Cross While Talking About Donald Trump

  Joe Biden Jokingly Makes Sign of the Cross While Talking About Donald Trump The president described Republican California gubernatorial candidate Larry Elder as a 'Trump clone.'Biden spoke at Long Beach during Newsom's final campaign event before the recall election on Tuesday, when the Democratic governor hopes to remain in office and see off a challenge from his main Republican rival, Larry Elder.

The woolly mammoth (Mammuthus primigenius) is a species of mammoth that lived during the Pleistocene until its extinction in the Holocene epoch.

Scientists have now analyzed the mammoth to understand how it lived and died — and whether it will yield enough undamaged DNA to make cloning the extinct creature a reality. The wooly mammoth , just like many prehistoric / ice age animals are dead and gone for a reason - the earth' s climate and environment change, they could not adapt and natural selection played its part. IF we succeed in bringing a mammoth to life - what purpose does it serve than to stroke our own scientific egos?

If Colossal does manage to produce baby mammoth-like elephants, the company will face serious ethical questions. Is it humane to produce an animal whose biology we know so little about? Who gets to decide whether they can be set loose, potentially to change the ecosystems of tundras in profound ways?

… Heather Bushman, a philosopher at the London School of Economics, said that whatever benefits mammoths might have to the tundra will need to be weighed against the possible suffering that they might experience in being brought into existence by scientists.

“You don’t have a mother for a species that — if they are anything like elephants — has extraordinarily strong mother-infant bonds that last for a very long time,” she said. “Once there is a little mammoth or two on the ground, who is making sure that they’re being looked after?”

Considering the recent controversy surrounding much simpler gain-of-function research, perhaps it’s best to leave this idea in the ground for now — or, even better, to actually put political resources toward preventing the

worst outcomes of the climate crisis rather than play around with deep adaptation schemes that intentionally riff on Jurassic Park.

‘Hollywood Remixed’: Jose Antonio Vargas and ‘Blue Bayou’ Director/Star Justin Chon Tell Stories About Undocumented Immigrants .
The “Documenting the Undocumented” episode of Hollywood Remixed, The Hollywood Reporter‘s topical inclusion-themed podcast explores narratives about undocumented immigrants with two special guests. Pulitzer-winning journalist Jose Antonio Vargas is, for many, the public face and also voice for undocumented immigrants in this country. The former Washington Post reporter learned the truth about his status as a teenager, then went public about it 14 years later. Since telling his own story in that 2011 New York Times Magazine essay, Vargas has now gone on to advocate for other immigrants through shaping the storytelling about them.
