“We do not intend to grow dinosaurs,” say scientists extracting DNA from insects stored in the resin.



Scientists who extracted genetic material from an insect stored in the resin, for the purposes of a recently published study, know what Jurassic Park overtones do, but assure the public that “we do not intend to raise dinosaurs.” To date, scientists cannot conclude that ancient DNA can live for millions of years inside resin-stored insects, thereby weakening the hopes of the real John Hammonds everywhere. A group of European scientists is specifically studying how long DNA can last in insects stored in resinous materials – the shelf life, if you will. These scientists have successfully extracted genetic material from resin samples aged two and six and hope that these new methods can be used for further research on much older samples.

“However, we do not intend to raise dinosaurs,”

; said Dr. Monica Solorzano-Kremer of the Senkenberg Research Institute and the Museum of Natural History. “Rather, our current study is a structured attempt to determine how long the DNA of insects enclosed in resinous materials can be stored.”Past attempts to remove ancient DNA from millions of years or hundreds of thousands of years of fossil resins have been criticized or deemed unsuitable for genetic research as “the result of modern pollution and lack of reproducibility.”

As recently published in the journal PLOS, the scientists stated: “Our goal is not to start an uncontrolled search for ADNA in amber, as was the case in the past, but to start addressing the main aspects of DNA preservation in resin and We conclude that the genomics of resin-embedded organisms can therefore be studied, although time limits have yet to be determined. “

In other words, they can now successfully extract genetic material from samples stored in amber, but it is unclear whether the genetic material can actually be stored for millions of years in this state (unlike other fossils). This study has shown that genetic material can last up to six years, but can ancient DNA – well, let’s just say, dinosaur DNA – actually survive in fossilized resins for millions of years?

At present, the answer is no or at least very unlikely, but these scientists hope to determine how long the genetic material can be stored in future research using modern genomic techniques used in this study.

“Our experiments show that the water in the inclusions is stored much longer than previously thought. It can also affect the stability of genetic material. Extraction of functional DNA from amber, which is several million years old, is unlikely,” said Dr. Solorzano. -Kremer.

But are these scientists so concerned about whether or not they can, they didn’t stop and think, is it worth it? Well, the fact that they encounter a Jurassic park suggests that they don’t want predators to come to life either.
