Bacteriophages are small, virus-like organisms that infect bacteria. They are comprised of a protein capsule around an RNA or DNA genome.
As conceived by Charles Darwin in the 1800s, evolution is a slow, gradual process during which species adaptations are inherited incrementally over generations.
The Mariana Trench, the deepest location on Earth, descends over 11,000 meters to the Pacific Ocean’s seafloor at its shallowest point. Even in the utterly desolate darkness, life exists.
Researchers discovered a new type of marine bacteria with distinct traits on the ocean floor.
Researchers from University of British Columbia and Michigan State University have invented a system that can quickly and inexpensively detect airborne viruses using the same technology that enables high-speed trains.
Viruses are usually associated with illness. But our bodies are full of both bacteria and viruses that constantly proliferate and interact with each other in our gastrointestinal tract.
The Centers for Disease Control and Prevention warns that the increase in cases of the drug-resistant bacterial infection Shigella could be a predictor of what's to come for other bacteria.
As conventional antibiotics continue to lose effectiveness against evolving pathogens, scientists are keen to employ the bacteria-killing techniques perfected by bacteriophages, the viruses that infect bacteria.
Genetic variations, such as mutations, recombinations, or transpositions occur naturally in cultured microorganisms and are often considered nonneutral mutations.
An Aston University scientist has developed the world’s first computer reconstruction of a virus, complete with its native genome.
This week, the United Nations is meeting in Montreal for the UN Biodiversity Conference. The conference brings together leaders from around the world to discuss how to prevent loss of biodiversity and how to restore habitats that are already hurting.
Researchers at McMaster University have created a powerful new weapon against bacterial contamination and infection.
Bacteria use a wide range of defense strategies to combat viral infection, and some of these systems have resulted in game-changing technologies like CRISPR-based gene editing.
A new procedure for controlling directed evolution in bacteria is developed and demonstrated by scientists at North Carolina State University.
Mycobacterium abscessus, a relative of the bacteria that cause tuberculosis and leprosy, is responsible for particularly severe damage to human lungs and can be resistant to many standard antibiotics, making infections extremely challenging to treat.
The risk of antibiotic resistance increases as bacteria continue to evade even the most powerful contemporary medicinal treatments. Antibiotic-resistant microorganisms threaten to take more than 10 million lives by 2050, as present-day treatments prove ineffective.
DNA is made up of nucleobases, which are depicted by the letters G, A, T, and C. They are the foundation of the genetic code.
Crop plants and animals can be infected by bacterial pathogens that reduce yield, cause food wastage, and carry human pathogens that spread disease on consumption.
Gene editing for the development of new treatments, and for studying disease as well as normal function in humans and other organisms, may advance more quickly with a new tool for cutting larger pieces of DNA out of a cell's genome, according to a new study by UC San Francisco scientists.
Australian researchers have shown how viruses can be used to save lives, developing the potential use of bacteriophages in bandages to treat life-threatening golden staph infections which may not respond to traditional antibiotics.
A research team from the Severinov Laboratory at Skoltech, together with their collaborators from Israel and Switzerland, has analyzed a bacterial BREX defense mechanism that was poorly studied to date.
