Polymerase Chain Reaction News and Research

RSS

Polymerase chain reaction (PCR) is a revolutionary laboratory technique that enables the replication of a specific DNA sequence. Using PCR, millions of copies of a target DNA can be easily synthesized within a short period of time.

Study discovers new species of green microalga in São Paulo

A group led by researchers affiliated with the Phycology Laboratory at the Federal University of São Carlos (UFSCar) in the state of São Paulo, Brazil, have discovered a new species of green microalga in a reservoir located in the northwest of the state.

Accurate diagnosis of bacterial superinfection pneumonia could help avoid antibiotic overuse

Only 21 percent of patients with severe pneumonia caused by SARS-CoV-2 (the virus that causes COVID-19) have a documented bacterial superinfection at the time of intubation, resulting in potential overuse of antibiotics, according to new research published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.

New method helps tests large groups for SARS-CoV-2 infection

Researchers at the Vienna BioCenter designed a testing protocol for SARS-CoV-2 that can process tens of thousands of samples in less than 48 hours. The method, called SARSeq, is published in the journal Nature Communications and could be adapted to many more pathogens.

Telomere length decreases most rapidly from birth to age 3, shows study

Telomeres are protective caps on DNA that shorten as we grow older. Now, one of the first studies to examine telomere length (TL) in childhood finds that the initial setting of TL during prenatal development and in the first years of life may determine one's TL throughout childhood and potentially even into adulthood or older age.

Environmental DNA helps track down species on the move

Many individuals would like to prevent sloughed-off skin and bodily fluids. However, for marine biologists like Cheryl Lewis Ames, Associate Professor of Applied Marine Biology in the Graduate School of Agricultural Science at Tohoku University (Japan), such life remnants have become a magical guide to detecting the unseen.
