More than meows: How bacteria help cats communicate
Many mammals, from domestic cats and dogs to giant pandas, use scent to communicate with each other. A new study from the University of California, Davis shows how domestic cats send signals to each other using odors derived from families of bacteria.....»»
Newly-discovered bacterial regulatory mechanism has implications for antibacterial control measures
Research spearheaded by four biologists within the College of Arts and Sciences at Indiana University Bloomington has uncovered a new regulatory mechanism shared by many bacteria, which may have profound implications for anti-bacterial control measur.....»»
Unlocking the world of bacteria—researchers introduce new approach to make bacteria amenable to genetic engineering
Bacteria populate virtually every habitat on Earth, including within and on our own bodies. Understanding and engineering bacteria can lead to new methods for diagnosing, treating, and preventing infections. Additionally, it presents opportunities to.....»»
Lichen partnerships challenged by changes in the Northwoods
Lichen, which people may think of as a single organism, is in fact a community of several species that depend on each other for survival. Lichen symbiosis includes at least one fungus and one alga, along with other fungi and bacteria in roles that ar.....»»
Study identifies biting flies as reservoirs of bacteria that cause bovine mastitis on dairy farms
Bovine mastitis, which affects cows, leads to reduced milk production and can be fatal if left untreated. The USDA National Animal Health Monitoring System has reported cases in 99.7% of all dairy operations in the U.S., making it the most prevalent.....»»
The mythical griffin was not inspired by a horned dinosaur, study concludes
The mythological creatures are instead "chimeras of big cats and raptorial birds." Enlarge / Painting of a gryphon, or griffin, a lion-raptor chimera from ancient folklore. (credit: Mark Witton) The gryphon, or griffin,.....»»

Global South health care practices contribute to spread of antimicrobial resistance across the world, study suggests
Many bacteria resistant to multiple antibiotics originate in Pakistan and other parts of the Indian subcontinent. Infections caused by these bacteria are challenging to treat; longer treatment with broad-spectrum antibiotics is required and despite t.....»»
Mashed up purple marine bacteria makes an excellent eco-friendly fertilizer
New research published in npj Sustainable Agriculture reports that biomass made from the purple photosynthetic marine bacterium Rhodovulum sulfidophilum is an excellent nitrogen fertilizer......»»
Many more bacteria produce greenhouse gases than previously thought, study finds
Caltech researchers have discovered a new class of enzymes that enable a myriad of bacteria to "breathe" nitrate when in low-oxygen conditions. While this is an evolutionary advantage for bacterial survival, the process produces the greenhouse gas ni.....»»
Hidden partners: Symbiodolus bacteria found in various insect orders
Scientists at the Max Planck Institute for Chemical Ecology report the discovery of at least six orders of endosymbiont Symbiodolus clandestinus, which lives inside insect cells. Using fluorescence in situ hybridization, they showed that Symbiodolus.....»»
Using soil bacteria to help accelerate discovery of new antibiotics
Northeastern researcher Kim Lewis is spearheading an effort to accelerate discovery of new antibiotics as part of a multi-institutional project to tackle the growing problem of antibiotic resistance......»»
Old drugs new tricks—novel approach shows "enormous potential" for rapid antibiotic discovery
An innovative project to re-purpose existing drugs for their potential as antibiotics has uncovered a highly promising candidate with a potent and unique way of killing drug resistant bacteria......»»
Tweets analyzed by scientists offer insight into effective hurricane risk messaging
Forecasters can use images in social media to better communicate weather related hazards of hurricanes, according to a pair of new studies. The findings are published in the journals Natural Hazards Review and Weather, Climate, and Society.....»»
Investigating nematode-microbe interactions in lab-simulated decomposed beetle environments
Beneath the surface, bacterivorous nematodes are key players in the nutrient cycle, consuming bacteria that decompose organic matter. Traditionally, these nematodes are studied in laboratory environments where isolated bacterial strains are used to m.....»»
To kill the competition, bacteria throw pieces of dead viruses at them
A network of mutual murder ensures that diverse populations of bacteria survive. Enlarge / This is an intact phage. A tailocin looks like one of these with its head cut off. (credit: iLexx) Long before humans became inte.....»»
Upper surface of coastal waters can accumulate bacteria and antibiotics, study finds
Antibiotics in the uppermost water surface, known as the sea surface microlayer, can significantly affect the number of bacteria present and contribute to the adaptation of marine bacteria against widely used antibiotics. In new research presented at.....»»
A compound produced by symbiotic bacteria promotes in vitro protein synthesis
A research team led by Associate Professor Atsushi Nakabachi of the Toyohashi University of Technology Research Center for Agrotechnology and Biotechnology has revealed that the compound diaphorin produced by an insect symbiotic bacterium promotes th.....»»
Research reveals plant pathogens repurpose phage elements for bacterial warfare
Bacteriophages, viruses that attack and destroy bacteria, are everywhere in the natural world where they play a vital role in regulating microbe populations in ways that are not yet well understood......»»
Not wrapping but folding: Bacteria also organize their DNA, but they do it a bit differently
Some bacteria, it turns out, have proteins much like ours that organize the DNA in their cells. They just do it a bit differently. This is revealed by new research from biochemists at the Leiden Institute of Chemistry and the Max Planck Institute for.....»»
Elephants may refer to each other by name
