How bacteria hunt bacteria
We commonly know predator-prey relationships from the animal kingdom, but they are also a survival strategy of certain bacteria: bacterial predators actively kill bacteria of other species in order to feed on them. The predatory species include many.....»»
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.....»»
Thanks to humans, Salish Sea waters are too noisy for resident orcas to hunt successfully
The Salish Sea—the inland coastal waters of Washington and British Columbia—is home to two unique populations of fish-eating orcas, the northern resident and the southern resident orcas. Human activity over much of the 20th century, including red.....»»
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......»»
Archaeologists suggest Neolithic Scandinavians may have used skin boats to hunt, travel and trade
Recent research by Dr. Mikael Fauvelle and his colleagues, published in the Journal of Maritime Archaeology, proposes that the neolithic Pitted Ware Culture (PWC) may have used skin boats to conduct trade, travel, fishing, and hunting activities......»»
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.....»»
Composite plastic degrades easily with bacteria, offers environmental benefits
Billions of tons of plastic waste clutter our world. Most of it has accumulated on the ground and in the oceans or disintegrated into tiny particles known as microplastics that pollute the air and the water, penetrating vegetation and the bloodstream.....»»
US disinformation researcher laments "incredible witch hunt"
Understanding disinformation has emerged as a lightning rod in the United States ahead of the November election, with academics and think-tanks facing lawsuits by right-wing groups and subpoenas from a Republican-led congressional committee......»»
Massive underwater eruption may preview deep-sea mining destruction
Scientists are exploring the underwater aftermath of the 2022 Hunga eruption. Enlarge / Following the 2022 Hunga volcano eruption, a nearby hydrothermal vent was seen coated with a white mat of bacteria and surrounded by a thick.....»»
Japanese island eradicates rabbit-killing mongoose
Japan has wiped out all mongooses on a subtropical island, officials said, after the animals ignored the venomous snakes they were brought in to hunt and preyed on endangered local rabbits instead......»»
Human mouth bacteria reproduce through rare form of cell division, research reveals
One of the most diverse ecosystems on the planet is closer than you think—right inside your mouth. Your mouth is a thriving ecosystem of more than 500 different species of bacteria living in distinct, structured communities called biofilms. Nearly.....»»
New discovery of how bacteria navigate their environment could change how we treat infection
Scientists from the University of Sheffield have discovered a new sensory capability in bacteria which could transform treatments for bacterial infections......»»
Hunt for rare bird shows how Ecuador narco violence impedes research
Biologist Cesar Garzon was searching for a small, endangered parakeet in southern Ecuador when he was warned he may be kidnapped, highlighting the danger for scientists in the biodiverse country engulfed in narco violence......»»
New discoveries about how mosquitoes mate may help the fight against malaria
A high-pitched buzzing sound in your ear is an unmistakable sign that a female mosquito is out on the hunt—for they, not males, drink blood. Hearing that tone might make you turn to try to swat the pest. But for a male mosquito, that tone means it'.....»»
Bacteria able to overcome cost of vancomycin resistance in lab setting
Staphylococcus aureus has the potential to develop durable vancomycin resistance, according to a study published August 28, 2024, in the open-access journal PLOS Pathogens by Samuel Blechman and Erik Wright from the University of Pittsburgh, U.S.......»»
