Lower antibiotic resistance in intestinal bacteria with forgotten antibiotic
A forgotten antibiotic, temocillin, led to lower selection of resistant bacteria than the standard treatment for febrile urinary tract infection. Thus, temocillin may be useful in treating severe urinary tract infections that give rise to fever, and.....»»
Nutrient resorption is related to drought resistance traits of savanna plants, research finds
Leaf nutrient resorption and drought resistance are critical for plant growth and survival. However, our understanding of the relationship between leaf nutrient resorption and plant drought resistance remains limited......»»
Women and people of color remain "invisible" as most people pick white men as their heroes, researchers say
Women and people of color remain invisible to many people in Britain and the U.S. as people pick white men as their heroes instead, a study shows. Their achievements are often forgotten or not recognized when people are choosing who inspires them, re.....»»
Tiny hitchhikers: Scientists uncover new "mini-satellites" in sea bacteria
Microbiologists led by Université de Montréal biologist Frédérique Le Roux have made an underwater breakthrough, discovering what they're calling "mini-satellites" in sea bacteria......»»
Team unravels activation mechanism of a protein that combats bacteria
The human immune system is constantly fending off a wide range of invaders—a feat that requires a diverse array of cellular troops and molecular weaponry. Although a great deal is already known about immune defense cells and the strategies they emp.....»»
Researchers engineer bacteria that eat plastic, make multipurpose spider silk
Move over Spider-Man: Researchers at Rensselaer Polytechnic Institute have developed a strain of bacteria that can turn plastic waste into a biodegradable spider silk with multiple uses......»»
Food-borne pathogen Listeria may hide from sanitizers in biofilms
An estimated 1,600 people in the U.S. contract a serious infection from Listeria bacteria in food each year, and of those individuals, about 260 people die, according to the Centers for Disease Control and Prevention. Penn State researchers may now b.....»»
Simulation observes three distinct phases of superconducting dynamics
In physics, scientists have been fascinated by the mysterious behavior of superconductors—materials that can conduct electricity with zero resistance when cooled to extremely low temperatures. Within these superconducting systems, electrons team up.....»»
New tool reveals gene behavior in bacteria
Bacterial infections cause millions of deaths each year, with the global threat made worse by the increasing resistance of the microbes to antibiotic treatments. This is due in part to the ability of bacteria to switch genes on and off as they sense.....»»
New method for incorporating structurally unusual amino acids into proteins
A team of biochemists at the Medical Research Council Laboratory of Molecular Biology at Cambridge has developed a new method to incorporate structurally unusual amino acids into proteins by using bacteria. The method is described in the journal Natu.....»»
Nanoparticle spray reduces risk of airborne bacterial infections caused by air filtration systems
A novel nanoparticle spray coating process has been shown to all but eliminate the growth of some of the world's most dangerous bacteria in air filtration systems, significantly reducing the risk of airborne bacterial and viral infections......»»
This underrated HBO show from the 2000s has been forgotten. Here’s why you should watch it now
This HBO show from the 2000s isn't as celebrated as The Sopranos or Mad Men. But it should be as it's just as great in 2024 as it was nearly 20 years ago......»»
When conditions cool down, a bacterial prey species becomes the predator
In a new study, two species of bacteria grown in a lab reversed their predator-prey relationship after one species was grown at a lower temperature. Marie Vasse of MIVEGEC, France, and colleagues have published these findings in PLOS Biology......»»
Study finds S. aureus" surface-sticking ability not evenly distributed over cell envelope
Infections caused by the bacterium Staphylococcus aureus have a significant impact on human health, with tens of thousands of hospital patients dying every year from infections due to the S. aureus "superbug." Stopping the spread of bacteria like S......»»
CRISPR off-switches: A path towards safer genome engineering?
Using CRISPR, an immune system bacteria use to protect themselves from viruses, scientists have harnessed the power to edit genetic information within cells. In fact, the first CRISPR-based therapeutic was recently approved by the FDA to treat sickle.....»»
Exploding kamikaze bacteria: How a few "soldier" cells confer virulence to a population by sacrificing themselves
You suddenly feel sick—pathogenic bacteria have managed to colonize and spread in your body. The weapons they use for their invasion are harmful toxins that target the host's defense mechanisms and vital cell functions. Before these deadly toxins c.....»»
Bacterial immune system boosts antibiotic effectiveness against cholera, study reveals
Bacteria have an immune system that protects them against viruses known as bacteriophages. A research team from the Universities of Tübingen and Würzburg has now shown how this immune system enhances the effect of specific antibiotics against the c.....»»
Researchers discover rare phages that attack dormant bacteria
In nature, most bacteria live on the bare minimum. If they experience nutrient deficiency or stress, they shut down their metabolism in a controlled manner and go into a resting state. In this stand-by mode, certain metabolic processes still take pla.....»»
Connecting researchers and legislators can lead to policies that reflect scientific evidence
Like most kids of the 1990s, I attended a school that used the original DARE program as a cornerstone initiative in the war on drugs. Congressional funding for this Drug Abuse Resistance Education program surged to over US$10 million per year by 2002.....»»
Status update in evolutionary race between humans and resistant bacteria: Two steps forward for us
In the span of one week, two researchers from Leiden are receiving their Ph.D.s, each of them on an important step in the battle against bacteria that are becoming increasingly resistant to antibiotics......»»
Researchers warn of global threat to crops as insecticide resistance emerges in bluegreen aphids
For the first time, researchers in Australia have documented insecticide resistance in field-collected populations of bluegreen aphids, Acyrthosiphon kondoi—a worldwide pest of pulses and other legume crops......»»
