Quantifying genetic variations in bacterial cultures the qSanger way
Genetic variations, such as mutations, recombinations, or transpositions occur naturally in cultured microorganisms and are often considered nonneutral mutations......»»
Human histones show promise in fighting bacterial infections
Antibiotics have saved millions of lives from infectious diseases and are considered one of the most important discoveries of the 20th century. However, as the use (and abuse) of antibiotics has increased over the years, many bacteria have developed.....»»
New insights into mango evolution: Study reveals extensive hybridization within the Mangifera genus
A research team investigated whole chloroplast genomes and nuclear gene sequences from 14 species, uncovering new insights into the genetic diversity and hybrid origins of mango species. They used the evolutionary relationships within the Mangifera g.....»»
Variations in scientific ethics: Chinese scientists prioritize government service more than global peers
In a new study of physicists from the U.S., U.K. and China, Rice University and Santa Clara University researchers found that Chinese scientists feel a greater obligation to serve their government with research efforts than international counterparts.....»»
Using machine learning to identify bacterial resistance genes and the drugs to block them
Antibiotic resistance is a growing public health problem around the world. When bacteria like E. coli no longer respond to antibiotics, infections become harder to treat......»»
A new genetic web tool can help restore climate-resilient marine ecosystems
In the face of increased human pressures and climate change, a team of Australian scientists led by Dr. Georgina Wood at Flinders University has launched a new online tool to assist marine managers and restoration experts to bolster the resilience of.....»»
Who should get paid for nature"s sequenced genes?
Much of the vanilla that flavors our ice cream today is artificial, derived from the genetic signature of a plant that hundreds of years ago was known only to an Indigenous Mexican tribe......»»
Coral exudates, not algae, linked to bacterial growth that threaten reefs
A study led by the University of Bremen suggests that on algae-dominated coral reefs, it is not the algae but the corals themselves that may contribute to the growth of harmful bacteria. This discovery suggests that a disturbance in the natural compo.....»»
Engineered bacterial protein offers efficient rare earth metal separation
A newly discovered protein naturally houses an unusual binding site that can differentiate between rare earth elements, and researchers at Penn State have made it even better. Rare earth elements are key components used in everything from modern tech.....»»
CRISPR-Cas10 can flood virally infected bacteria with toxic molecules, researchers discover
CRISPR-Cas9 has long been likened to a kind of genetic scissors, thanks to its ability to snip out any desired section of DNA with elegant precision......»»
Bacterial pathogen must balance between colonizing airways and developing antibiotic tolerance, study reveals
Imagine trying to settle into a new home while constantly being attacked. That's what the bacterium Pseudomonas aeruginosa faces when it infects the lungs, and it can't both spread and protect itself from antibiotics at the same time......»»
When ribosomes go rogue
Unusual variations in the cellular protein factory can skew development, help cancer spread, and more. But ribosome variety may also play biological roles, scientists say. In the.....»»
New technology illustrates bacterial "hibernation states"
Like hibernating bears, certain bacterial cells have the ability to shift into a "low-power" metabolic state in which they can stably survive without growing. This state is often seen in the context of antibiotic-resistant infections as bacteria form.....»»
Drug delivery system overcomes circulatory roadblock that prevents gene therapies from reaching their targets
Exploiting the remarkable capability of viruses to transport gene therapies past what until now has been a circulatory roadblock is at the heart of a University of Alberta-led discovery that promises to re-energize the field of genetic medicine......»»
The Tea-CUP project: Joint initiative to provide climate services to help the tea industry
Tea is a significant global commodity, with an industry worth tens of billions of dollars and growing. However, its production—both in terms of quantity and quality—is highly sensitive to climate variations, particularly in the context of long-te.....»»
Climate change to alter seasonal outdoor activity patterns in US
It can be hard to connect a certain amount of average global warming with one's everyday experience, so researchers at MIT have devised a different approach to quantifying the direct impact of climate change......»»
Structural biology analysis of a Pseudomonas bacterial virus reveals a genome ejection motor
The viruses that infect bacteria are the most abundant biological entities on the planet. For example, a recent simple study of 92 showerheads and 36 toothbrushes from American bathrooms found more than 600 types of bacterial viruses, commonly called.....»»
Discovery of new bacterial toxins could be key to fighting infections
Researchers have discovered a new group of bacterial toxins that can kill harmful bacteria and fungi, opening the door to potential new treatments for infections. These toxins, found in over 100,000 microbial genomes, can destroy the cells of bacteri.....»»
Genomic study offers hope for endangered Oriental stork
A new genomic study of the endangered Oriental stork reveals that the population's genetic health is still surprisingly strong, with high genetic diversity and low levels of inbreeding. This is an uncommon finding in most endangered species populatio.....»»
Team develops promising new form of antibiotic that makes bacterial cells self-destruct
To address the global threat of antibiotic resistance, scientists are on the hunt for new ways to sneak past a bacterial cell's defense system. Taking what they learned from a previous study on cancer, researchers from the University of Toronto (U of.....»»
Biofilms study reveals how multiple bacteria species manage to coexist
Biofilms—slimy communities of bacteria—grow on all sorts of surfaces: from glaciers and hot springs to plant roots, your bathtub and fridge, wounds, and medical devices such as catheters. Most biofilms are composed of multiple bacterial species,.....»»
