Study revealing the secret behind a key cellular process refutes biology textbooks

New research has identified and described a cellular process that, despite what textbooks say, has remained elusive to scientists until now—precisely how the copying of genetic material that, once started, is properly turned off.


The finding concerns a key process essential to life: the transcription phase of gene expression, which enables cells to live and do their jobs.

During transcription, an enzyme called RNA polymerase wraps itself around the double helix of DNA, using one strand to match nucleotides to make a copy of genetic material—resulting in a newly synthesized strand of RNA that breaks off when transcription is complete. That RNA enables production of proteins, which are essential to all life and perform most of the

Pfizer vaccine refutes Trump’s nationalism, science attacks

Pfizer’s announcement that its COVID-19 vaccine is 95% effective has created significant optimism — except in the Trump camp, where adverse reactions of cynicism have emerged. His acolytes believe the press release was timed to prevent an injection of good news that might have secured reelection.

It is true that Pfizer’s CEO wanted to distance his scientists from the overt politics that would have come with taking Operation Warp Speed money. The company didn’t take funding but entered into an agreement to supply the United States with vaccine once the Food and Drug Administration approved. Trump’s adult children believe this pact was a result of their father’s deal-making prowess — but such supply agreements are quite common.

Whether the release was sat on and prevented a second term for Trump is likely never to be known. Regardless, Americans should feel relief because nothing about this vaccine is to his credit.
