Biologists Extract E. Coli Genetic Code From 16th Century Mummy

Researchers reconstructed the genetic code of E. coli bacteria from an Italian nobleman who died in 1586. E. coli is commonly found in human and animal intestines, but certain strains can make people sick. Researchers hope their findings will allow scientists to study how the bacteria has evolved. Loading Something is loading. E. coli, short … Read more

Breeding 2,000 Generations of Bacteria May Have Solved This Major Debate in Biology

Since the dawn of genetics in the early 20th century, biologists have debated whether evolution is driven more by chance mutations or by the original diversity in the gene pool. Having a lot of genetic options to choose from might make natural selection move a lot faster at the start, but do the genetic mutations … Read more

Genetic discovery could spell mosquitoes’ death knell – BIOENGINEER.ORG

A UC Riverside genetic discovery could turn disease-carrying mosquitoes into Peter Pans insect, preventing them from ever maturing or multiplying. A UC Riverside genetic discovery could turn disease-carrying mosquitoes into Peter Pans insect, preventing them from ever maturing or multiplying. In 2018, UCR entomologist Naoki Yamanaka found, contrary to accepted scientific wisdom, that an important … Read more

Climate-associated genetic switches found in plants

UNIVERSITY PARK, Pa. – Genetic variants that can act as switches directing structural changes in the RNA molecules that code for proteins in plants have been experimentally validated in plants for the first time. The changes to RNA structure can affect the molecule’s stability, how it interacts with other molecules, and how efficiently it can … Read more

Genomic analysis provides a deeper understanding of DCIS biology

A new study led by the global Cancer Grand Challenges PRECISION team, including researchers from The University of Texas MD Anderson Cancer Center, shifts the long-held belief that all invasive breast cancers following ductal carcinoma in situ (DCIS) arise from the original DCIS lesion. The results, published today in Nature Geneticsdemonstrate that roughly one in … Read more

Study: Most ‘silent’ genetic mutations are ha

In the early 1960s, University of Michigan alumnus Marshall Nirenberg and a few other scientists deciphered the genetic code of life, determining the rules by which information in DNA molecules is translated into proteins, the working parts of living cells. They identified three-letter units in DNA sequences, known as codons, that specify each of the … Read more

Massive New Study Confirms Being Tall Puts You at Risk of a Bunch of Diseases

Standing head and shoulders above the crowd has its perks – but those extra inches can come at a cost. According to a new study, being tall is fundamentally associated with a number of diseases, from varicose veins to peripheral nerve damage. An international team of researchers compared measures of height, both genetic and physical, … Read more
