Greenland melting likely increased by bacteria in sediment
Bacteria are likely triggering greater melting on the Greenland ice sheet, possibly increasing the island's contribution to sea-level rise, according to Rutgers scientists......»»
Right whale population grows 4% but extinction remains a threat
One of the rarest species of whale in the world has increased slightly in population, encouraging conservationists to call on the federal government and the shipping and fishing industries to do more to bring the giant animals back from the brink of.....»»
Discovery of new bacterial toxins could be key to fighting infections
Researchers have discovered a new group of bacterial toxins that can kill harmful bacteria and fungi, opening the door to potential new treatments for infections. These toxins, found in over 100,000 microbial genomes, can destroy the cells of bacteri.....»»
Rare fossils of extinct elephant document the earliest known instance of butchery in India
During the late middle Pleistocene, between 300 and 400 thousand years ago, at least three ancient elephant relatives died near a river in the Kashmir Valley of South Asia. Not long after, they were covered in sediment and preserved along with 87 sto.....»»
Unexpected beauty and major antimicrobial power boost as phages form into surprising flower shapes
A group of McMaster researchers who routinely work with bacteriophages—viruses that eat bacteria—had a pleasant and potentially very important surprise while preparing slides to view under a powerful microscope......»»
"Nano-weapon" discovery boosts fight against antibiotic-resistant hospital superbugs
Researchers have discovered how a bacteria found in hospitals uses "nano-weapons" to enable their spread, unlocking new clues in the fight against antibiotic-resistant superbugs......»»
Chemical trick activates antibiotic directly at the pathogen
Colistin is a last-resort antibiotic that is usually only used for severe infections with resistant bacteria. This is due to its severe kidney-damaging side effects, which occur in about 30% of treated patients. A research team at the Helmholtz Cente.....»»
Materials of the future can be extracted from wastewater
A group of researchers is on the way to revolutionizing what biomass from wastewater treatment plants can be used for. Biopolymers from bacteria can be a sustainable alternative to oil-based products, and phosphorus and other minerals can also be har.....»»
A method to switch between optical pulling and pushing forces by altering the shape of Fermi arcs in Weyl systems
Optical forces, which act like an invisible "hand," are capable of precisely controlling tiny particles. Optical tweezers, a well-known tool, use this force to capture and manipulate small objects such as cells, bacteria, and viruses. This effect is.....»»
Biofilms study reveals how multiple bacteria species manage to coexist
Biofilms—slimy communities of bacteria—grow on all sorts of surfaces: from glaciers and hot springs to plant roots, your bathtub and fridge, wounds, and medical devices such as catheters. Most biofilms are composed of multiple bacterial species,.....»»
Catching prey with grappling hooks and cannons: The unusual weapons arsenal of a predatory marine bacterium
Countless bacteria call the vastness of the oceans home, and they all face the same problem: the nutrients they need to grow and multiply are scarce and unevenly distributed in the waters around them. In some spots they are present in abundance, but.....»»
Pathogenic system found on Providencia rustigianii has virulence gene akin to Salmonella"s
Salmonella and E. coli are well-known bacteria that cause food poisoning, but less understood are species of Providencia, another causative agent of serious symptoms......»»
GPT-4-based AI agents show promise for detecting antimicrobial resistance
Researchers at the University of Zurich (UZH) have used artificial intelligence (AI) to help identify antibiotic-resistant bacteria. The team led by Adrian Egli, UZH professor at the Institute of Medical Microbiology, is the first to investigate how.....»»
Mangrove microbes show potential for breaking down plastics
A way to select a suite of mangrove bacteria that can transform plastic has been developed that potentially offers a new strategy in the global toolkit of plastic waste cleanup. Researchers have assessed the impact of polyethylene terephthalate (PET).....»»
Flexible approach to office hours promotes academic support, peer connections, increased student participation
Students don't wine at Ana Benaduce's happy hours. They don't whine either......»»
Coastal cities have a hidden vulnerability to storm-surge and tidal flooding that"s entirely caused by humans
Centuries ago, estuaries around the world were teeming with birds and turbulent with schools of fish, their marshlands and endless tracts of channels melting into the gray-blue horizon......»»
Targeting bacteria: Auxiliary metabolic genes expand understanding of phages and their reprogramming strategy
Viruses that infect bacteria—known as bacteriophages—could be used in a targeted manner to combat bacterial diseases. They also play an important ecological role in global biogeochemical cycles. Recent research by researchers at the University of.....»»
Each glacier has a unique organic matter composition, study reveals
Melting glaciers release more than just water. Organic matter once trapped in ice can run into streams and rivers, where it becomes food for microbes. These organisms respire the organic matter back to the atmosphere in the form of carbon dioxide, wi.....»»
Fossil pollen reveals history of Southern Hemisphere Westerlies
In Bergen, Maaike Zwier analyzed pollen in sediment cores from lakes on Kerguelen Islands and South Georgia. In this way, she can say something about the local climate going back almost 12,000 years. The study is published in the journal Quaternary S.....»»
Bacteria discovered in healthy vertebrate brains point to a potential role in brain function
Researchers at the University of New Mexico have identified the presence of bacteria in the healthy brains of fish. Understanding this connection between bacteria and animal brains could have future implications for the study of Alzheimer's disease......»»
New bacteria-based therapy shows promise for fighting cancer
Even as cancer remains a leading cause of death globally, bacteria-based cancer therapy presents an exciting and innovative treatment option. Owing to their ability to penetrate the rigid stromal barrier, bacteria can naturally target solid tumors an.....»»
