These Nanobots Can Swim Around a Wound and Kill Bacteria
Researchers have created autonomous particles covered with patches of protein “motors.” They hope these bots will tote lifesaving drugs through bodily fluids......»»
AI tools help uncover enzyme mechanisms for lasso peptides
Lasso peptides are natural products made by bacteria. Their unusual lasso shape endows them with remarkable stability, protecting them from extreme conditions. In a new study, published in Nature Chemical Biology, researchers have constructed and tes.....»»
How a bacterial pathogen that causes dysentery manipulates molecular activity to assure its survival
Virginia Tech researchers have learned how bacteria manipulate molecules to infect the host organism. Daniel Capelluto and his research team have discovered the mechanism by which the bacterial pathogen Shigella flexneri, the causative agent of dysen.....»»
Harnessing exosomes and hydrogels for advanced diabetic wound healing
Diabetes, a widespread condition affecting approximately 13% of American adults, is often accompanied by complications such as impaired wound healing. If left unchecked, this can lead to severe outcomes, including the need for amputation......»»
Plant pathogen battle: A tomato protein"s dual role in defense and susceptibility
Tomatoes, a staple crop worldwide, are increasingly threatened by biotic stressors such as viruses, fungi, and bacteria, with the effects worsening under climate change. These challenges lead to reduced yields and compromised nutritional quality, hig.....»»
Harmless strain of E. coli bacteria may be able to prevent urinary tract infections
Researchers from the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) and the College of Engineering are collaborating on a project that uses harmless strains of E. coli bacteria to disrupt the bacteria responsible for urinary.....»»
Scientists identify 18 bacterial strains to treat antibiotic-resistant gut infections
Antibiotic-resistant bacterial infections often occur in patients with chronic inflammatory intestinal conditions, such as inflammatory bowel disease, and in patients who have taken antibiotics for a long time. Gram-negative bacteria such as Enteroba.....»»

Do bacteria age?
Any organism that lives, grows and reproduces must also age. People often think of aging in the physical sense—gray hair, slowed movements and wrinkles—but aging fundamentally occurs on a molecular level, inside of cells......»»
Scientists decipher the energy patterns in our cells
Our cells harness energy for essential functions such as division, wound healing, and our immune response to diseases including cancer. But until now, the mechanics of how that energy affects cell behavior—and how this relates to health outcomes—.....»»
The power of one: Study finds solitary carnivores outkill group hunters
Earth's majestic "apex predators" are some of the most prolific hunters in the world. But which ones kill the most?.....»»
Soil pH drives microbial community composition: Study shows how bacteria work together to thrive in difficult conditions
Though a founding concept of ecology suggests that the physical environment determines where organisms can survive, modern scientists have suspected there is more to the story of how microbial communities form in the soil......»»
How bacteria actively use passive physics to make biofilms
When we think about bacteria, we may imagine single cells swimming in solution. However, similarly to humans, bacterial cells often socialize, using surfaces to coalesce into complex heterogeneous communities called biofilms. Within a group, bacteria.....»»
How the oceans" most abundant bacteria impact global nutrient flows
If you were to collect all the organisms from the ocean surface down to 200 meters, you'd find that SAR11 bacteria, though invisible to the naked eye, would make up a fifth of the total biomass. These bacteria, also known as Pelagibacterales, have ev.....»»
Researchers identify new tools for anti-Acinetobacter drug development and AMR preparedness
University of Liverpool researchers have engineered a library of strains that can be used to develop new antibacterial compounds to help address antimicrobial resistance (AMR) in Acinetobacter baumannii bacteria......»»
Crispr-Enhanced Viruses Are Being Deployed Against UTIs
With antibiotics losing their effectiveness, one company is turning to gene editing and bacteriophages—viruses that infect bacteria—to combat infections......»»
Researchers find live fungi, bacteria and viruses high in the Earth"s atmosphere
A team of climate, health and atmospheric specialists in Spain and Japan has found abundant live fungi, bacteria and viruses high in the Earth's atmosphere. In their study published in the Proceedings of the National Academy of Sciences, the group co.....»»
Silver nanoparticles and a new sensing method can fight back against antibiotic-resistant biofilms
From safeguarding our food supply to preventing hospital infections, the battle against antibiotic-resistant bacteria is a growing challenge. Some bacteria can form biofilms, thick aggregates of millions of individual cells surrounded by protective m.....»»
Hijacking the command center of the cell: Nuclear parasites in deep-sea mussels
Most animals live in intimate relationships with bacteria. Some of these bacteria live inside the cells of their hosts, but only very few are able to live inside cell organelles (structures inside the cell, like organs in the body). One group of bact.....»»
Phage editing technology could lead to alternative treatments for antibiotic-resistant bacteria
As antibiotic resistance becomes an increasingly serious threat to our health, the scientific and medical communities are searching for new medicines to fight infections. Researchers at Gladstone Institutes have just moved closer to that goal with a.....»»
Algorithm maps protein degradation patterns to improve infection diagnosis and treatment
Peptides are small fragments of proteins, mainly found in the skin and mucous membranes. Some peptides act as a barrier, protecting the body against infections by fighting off microorganisms like bacteria, viruses, and other pathogens, while others p.....»»
