Campylobacter strains exchange genes, can become more virulent and antibiotic resistant
New research from North Carolina State University has found that Campylobacter bacteria persist throughout poultry production—from farm to grocery shelves—and that two of the most common strains are exchanging genetic material, which could result.....»»
Animal social interactions could speed up evolution
Scientists typically predict how species evolve by looking at their genes and the environment they live in, but new research from the University of Aberdeen has highlighted a key factor that's often overlooked: social interactions, where the genes of.....»»
Genetic mechanism unlocks a key secret behind disease infection in crops
Researchers have unraveled a key genetic mechanism behind the way pathogens infect crops, leading to new strategies for breeding resistant crop varieties against other pathogens carrying the same genetic mechanism......»»
Researchers discover how plants produce a novel anti-stress molecule
New research identifies for the first time the genes that help plants grow under stressful conditions—with implications for producing more sustainable food crops in the face of global climate change......»»
Research team develops metallodrug-antibiotic combination strategy to combat superbugs
Antimicrobial resistance (AMR) bacterial infections have become a serious problem threatening human health worldwide. The overuse of antibiotics has promoted drug-resistant mutations in bacteria, causing almost all clinically used antibiotics to deve.....»»
Nobel Prize in medicine awarded for discovery of microRNAs, the molecules that control our genes
Two scientists, Victor Ambros (UMASS Chan Medical School in the US) and Gary Ruvkun (Harvard Medical School in the US), have won the 2024 Nobel prize in medicine or physiology......»»
Medicine Nobel goes to previously unknown way of controlling genes
MicroRNAs control the activity of many key genes but were unknown before 1993. On Monday, the Nobel Committee announced that two US researchers, Victor Ambros and Gary Ruvkun, wil.....»»
Phage cocktail shows promise against drug-resistant bacteria
Researchers have a new battle tactic to fight drug-resistant bacterial infections. Their strategy involves using collections of bacteriophages, viruses that naturally attack bacteria. In a new study, researchers at the University of Chicago Pritzker.....»»
Study identifies compounds that extend longevity of Japanese morning glory flowers
The longevity of plant flowers is controlled by genetically programmed mechanisms. After a certain amount of time after flowering, the expression of genes associated with programmed cell death is induced and cellular components such as proteins and n.....»»
First-ever artificial cell nuclei created in living egg from purified DNA injection
A research group is the first in the world to succeed in constructing artificial cell nuclei by injecting purified DNA solution instead of sperm into living mouse eggs. Their findings are published in the journal Genes to Cells......»»
One-minute phone breaks could help keep students more focused in class and better in tests
Phones can be useful tools in classrooms to remind students of deadlines or encourage more exchange between students and teachers. At the same time, they can be distracting. Students report using their phones for non-academic purposes as often as 10.....»»
Researchers develop first banana plant resistant to TR4 and black sigatoka
Researchers have developed a banana plant that is resistant to both fusarium tropical race 4 (TR4) and black sigatoka, two of the most destructive diseases for bananas......»»
Research provides new insights into role of mechanical forces in gene expression
The genome inside each of our cells is modeled by tension and torsion—due in part to the activity of proteins that compact, loop, wrap and untwist DNA—but scientists know little about how those forces affect the transcription of genes......»»
Corporate social responsibility can boost a company"s bottom line
Can companies do well by doing good? Research in the International Journal of Productivity and Quality Management that has looked at companies listed on the Tehran Stock Exchange (TSE) provides a positive answer to that question. The researchers have.....»»
Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
The biological marvels of the seabed are being mined to create commercial products—here are the risks
Thousands of genes from deep-sea marine life are being used to create new commercial products ranging from pharmaceuticals to cosmetics. Genes are segments of DNA that provide instructions for making other molecules that are essential for the structu.....»»
Semimetal-induced covalency achieves high-efficiency electrocatalysis for platinum intermetallic compounds
Compared with other types of batteries, proton exchange membrane fuel cells have the advantages of high discharge power and no pollution, which is also an important carrier for hydrogen energy conversion and utilization. Platinum intermetallic compou.....»»
Bacterial "flipping" allows genes to assume different forms
Imagine being one cartwheel away from changing your appearance. One flip, and your brunette locks are platinum blond. That's not too far from what happens in some prokaryotes, or single-cell organisms, such as bacteria, that undergo something called.....»»
Naked mole-rat found to have lost infection-resistant proteins
Scientists have found that the naked mole-rat—an underground rodent that lives up to 40 years—has lost a number of CD1 functional genes. The CD1 gene family in mammals is responsible for protein synthesis that protects the body against infectious.....»»
Graphene spike mat uses ordinary fridge magnet tech to fight antibiotic resistance
With strong bactericidal properties, graphene has the potential to become a game changer in the fight against antibiotic-resistant bacteria. So far there have been no efficient ways to control these properties—and thus no way to make use of graphen.....»»
Cloudflare helps secure popular messaging applications
Cloudflare announced a new service to verify the integrity of public keys in the end-to-end encryption of popular messaging applications. When using end-to-end encryption messaging applications, a public-private key exchange encrypts messages to prot.....»»
