The soft "spaghetti" of proteins that"s essential for the resistance of bacteria
Bacteria are increasingly resistant, especially to antibiotics, which is a major global health problem. An example, related to the pandemic? Covid weakens hospitalized people so much that we are now witnessing an upsurge in bacterial infections (resi.....»»
Nano-drugs hitching a ride on bacteria could help treat pancreatic cancer
Many pancreatic tumors are like malignant fortresses, surrounded by a dense matrix of collagen and other tissue that shields them from immune cells and immunotherapies that have been effective in treating other cancers. Employing bacteria to infiltra.....»»
Understanding cellular transcription responses to oxygen deprivation
A multiprotein complex is essential for regulating cellular responses to oxygen deprivation, a key feature of cancer, according to a Northwestern Medicine study published in the Proceedings of the National Academy of Sciences......»»
Antimicrobial peptide from cows shows potential for treating hypervirulent bacteria
University of Central Florida College of Medicine researcher Renee Fleeman is on a mission to kill drug-resistant bacteria, and her latest study has identified a therapy that can penetrate the slime that such infections use to protect themselves from.....»»

Survey: Most workers feel that AI can"t replace soft skills
A new survey from Wiley suggests workers do not feel artificial intelligence (AI) will be replacing the art of communication in the workplace......»»
Cell contraction drives the initial shaping of human embryos, study finds
Human embryo compaction, an essential step in the first days of an embryo's development, is driven by the contractility of its cells. This is the finding of a team of scientists from CNRS, Institut Curie, Inserm, AP-HP and the Collège de France. Pub.....»»
Researchers find that calcium can protect potato plants from bacterial wilt
Scientists have discovered that calcium plays a significant role in enhancing the resistance of potato plants to bacterial wilt. This disease causes worldwide losses of potatoes costing $19 billion per year. The findings open up new avenues for integ.....»»
Essential steps for zero-trust strategy implementation
63% of organizations worldwide have fully or partially implemented a zero-trust strategy, according to Gartner. For 78% of organizations implementing a zero-trust strategy, this investment represents less than 25% of the overall cybersecurity budget......»»
Researchers make a plastic that includes bacteria that can digest it
Bacterial spores strengthen the plastic, then revive to digest it in landfills. Enlarge (credit: Han Sol Kim) One reason plastic waste persists in the environment is because there's not much that can eat it. The chemical.....»»
How polyps of the moon jellyfish repel viral attacks on their microbiome
Bacteriophages, or phages for short, are viruses that infect bacteria and kill them through a lysis process. Phages can kill bacteria on or in a multicellular host organism, such as the polyp of the moon jellyfish. Phages specialize in specific bacte.....»»
Gene seekers discover atypical genes that control multiple valuable soybean traits
A team led by Purdue University soybean geneticist Jianxin Ma has developed a new biotechnological tool for the domestication of desirable traits from wild soybeans, such as resistance to leafhopper insect pests. The use of such tools, called de novo.....»»
Too many vehicles, slow reactions and reckless merging: New math model explains how traffic and bacteria move
What do the flow of cars on a highway and the movement of bacteria towards a food source have in common? In both cases, annoying traffic jams can form. Especially for cars, we might want to understand how to avoid them, but perhaps we've never though.....»»
UV light treats beet disease and combats fungicide resistance
Germicidal ultraviolet light is effective at killing a damaging fungus that infects table beets, adding an important organic tool to fight the growing problem of fungicide resistance, according to a new Cornell study......»»
Microgravity-grown crystals reveal new insights into protein structures
Biochemists have long been working around a blind spot when it comes to proteins. They know that hydrogen constitutes nearly half of the atoms in proteins, but how they contribute to protein function in these complex structures has been less clear. H.....»»
Bacteria "nanowires" could help develop green electronics
Engineered protein filaments originally produced by bacteria have been modified by scientists to conduct electricity. In a study published recently in the journal Small, researchers revealed that protein nanowires—which were modified by adding a si.....»»
CRISPR is promising to tackle antimicrobial resistance, but bacteria can fight back
In his presentation "How to use CRISPR-Cas to combat AMR" at the ESCMID Global Congress, Assistant Prof. Ibrahim Bitar, Department of Microbiology, Faculty of Medicine and University Hospital in Plzen, Charles University in Prague, Plzen, Czech Repub.....»»
Experts develop way to harness CRISPR technology to deal with antimicrobial resistance
Antimicrobial resistance (AMR) is continuing to increase globally, with rates of AMR in most pathogens increasing and threatening a future in which every day medical procedures may no longer be possible and infections thought long dealt with could ki.....»»
Study details a common bacterial defense against viral infection
One of the many secrets to bacteria's success is their ability to defend themselves from viruses, called phages, that infect bacteria and use their cellular machinery to make copies of themselves......»»
Researchers decipher how an enzyme modifies the genetic material in the cell nucleus
Inside the cell nucleus, the DNA molecule is found in a densely packed DNA-protein complex known as chromatin. Here the DNA is wrapped around a core of histone proteins and densely packed to form nucleosomes. The structure of the nucleosomes determin.....»»
New structures offer insight into how a bacterial motor powers bacterial chemotaxis, a key infectious process
Bacteria existed for millennia before humans and have been infecting us from the beginning. Although we can treat infections through pharmaceuticals, bacteria continue to become resistant to treatment thanks to their rapid evolution. Bacterial infect.....»»
