Biologists develop new method of cloning

DNA, which contains the genetic information of an organism, consists of long chains of nucleotides. In order to study the functions based on the sequence of these building blocks, DNA molecules must be inserted in carrier ...

Using tiny organisms to unlock big environmental mysteries

When you hear about the biological processes that influence climate and the environment, such as carbon fixation or nitrogen recycling, it's easy to think of them as abstract and incomprehensibly large-scale phenomena. Yet ...

New strategy may curtail spread of antibiotic resistance

Spotless surfaces in hospitals can hide bacteria that rarely cause problems for healthy people but pose a serious threat to people with weakened immune systems. Acinetobacter baumannii causes life-threatening lung and bloodstream ...

Genomic study of 412 anthrax strains provides new virulence clues

By analyzing genomic sequences from more than 400 strains of the bacterium that causes anthrax, researchers have provided the first evidence that the severity – technically known as virulence – of specific strains may ...

Addgene keeps flow of CRISPR plasmids fast and affordable

As a key global enabler of the revolutionary genome editing technology known as CRISPR, the nonprofit organization Addgene has made available more than 100,000 CRISPR plasmids (circular DNA fragments) to 3,400 laboratories ...

Bacteria can spread antibiotic resistance through soil

When most people think about bacterial antibiotic resistance, they think about it occurring in bacteria found in people or animals. But the environment surrounding us is a huge bacterial reservoir, and antibiotic resistance ...
