Don’t bring back the mammoth, scientist warns

  • Columbian Mammoth

    Sergio De la Rosa Martinez

They can … but they shouldn’t.

That’s the message from  Alice Roberts, a clinical anatomist, TV personality and professor of public engagement in science at England’s University of Birmingham. While advancements in science have made it possible to bring animals back from the dead, Roberts recently argued, it might not be morally right to do so.

'There's something really questionable about bringing back a single mammoth.'

"I would prefer the emphasis to be on saving existing animals under threat of extinction rather than trying to resurrect their long-extinct cousins,” Roberts said, according to a story at International Business Times.

The ethical issues surrounding “de-extinction” of a species were on debate during a March panel at the National Geographic Society.

Speakers include Chris Anderson, curator of the TED Conference talk series, Australian paleontologist Michael Archer and Spanish researcher Alberto FernDandez-Arias, who has worked on cloning a now-extinct goat.

Organizers of the event said dinosaurs aren't among the candidate species -- unlike in the movie "Jurassic Park."

Mammoths might be more realistic anyway: Japanese scientists have already extracted the bone marrow from woolly mammoth remains found in Siberia to look at the DNA, she said. But bringing those creatures may lead to unforseen problems.

"There's something really questionable about bringing back a single mammoth,” Roberts said.

"Mammoths are herd animals and their environment no longer exists, so what are you bringing that animal back for? You're bringing it back to live in a zoo?”

Meteorite crashes through roof in Connecticut, scientist says

A Yale scientist says a rock that crashed through the roof of a home in Wolcott was a meteorite.

Police say resident Larry Bech called them Saturday morning to report that his home had been damaged by a falling rock the night before.

Authorities suspected the object was a piece of runway from a nearby airport.

But Stefan Nicolescu, the collections manager for the Mineralogy Division at the Yale Peabody Museum, examined the rock and tells WVIT-TV it is a meteorite.

Nicolescu says the meteorite likely comes from the Lyrids meteor shower, which happens every year at this time when Earth crosses the orbit of comet Thatcher.

Aggressive Florida mosquito set to spoil summer, scientist says

If you live in Florida, a large, aggressive mosquito with a painful bite may soon be coming to a place near you.

One scientist at the University of Florida is predicting that another wave of Psorophora ciliate, sometimes called gallinippers, could be coming along with the summer’s rains.

The species is around a half an inch long with a black and white color pattern, the University of Florida News reports.

“The bite really hurts, I can attest to that,” said Phil Kaufman, an entomologist at the school.

Flooding from Tropical Storm Debbie unleashed huge numbers of the mosquitos throughout Florida last June, according to the University of Florida News.
