Modeling the collective movement of bacteria to better understand the formation of troublesome biofilms
Biofilms form when microorganisms such as certain types of bacteria adhere to the surface of objects in a moist environment and begin to reproduce resulting in the excretion of a slimy glue-like substance......»»
Global study reveals people, including those most affected by climate change, do not understand climate justice
An international study involving people from 11 countries has shown that most people, including those in areas most affected by climate change, don't understand the term "climate justice." However, they do recognize the social, historical, and econom.....»»
Better ocean connectivity boosts reef fish populations, finds study
Research led by the University of Oxford has found that oceanographic connectivity (the movement and exchange of water between different parts of the ocean) is a key influence for fish abundance across the Western Indian Ocean (WIO). The findings are.....»»
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......»»
New method for measuring luminescence lifetime offers versatility in scientific imaging
Oxygen is a key molecule for life, and in order to understand ecosystem dynamics it can be important to follow its ways in much detail. Optical sensors that use luminescent dyes have long been used to map oxygen levels in marine systems. Oxygen reduc.....»»
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).....»»
I used the brand new Oura Ring app. Here’s why you’ll want it
I've been using the redesigned Oura Ring app with the Oura Ring 3 and Oura Ring 4, and now understand if it's worth the monthly subscription or not......»»
Student debt: An individual and collective burden at English-language universities
Why do people feel it is legitimate to voluntarily take on debt in order to pursue higher education, and then challenge the debt burden later on, when it prevents them from enjoying the lifestyle that an education seemed to promise?.....»»
Electrophysiology study shows how ant toxin causes extreme pain
University of Queensland researchers have uncovered the workings of ant venom by measuring electric currents through individual channels in cells to understand how it causes pain......»»
Book Review: Inside the Global Movement to Protect Forests from Climate Change
Lessons from the people making forest ecosystems more resilient.....»»
You can make money on Threads, but not even those doing it understand how
If you’re looking to make money on Threads, it is possible, say creators, but there’s currently no clear roadmap on how to do so. Even those making thousands of dollars a month say they don’t know how it works … more….....»»
What we can learn from animals about death and mortality
Susana Monsó chats with Ars about her new book, Playing Possum: How Animals Understand Death. Human beings live every day with the understanding of our own mortality, but do anim.....»»
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.....»»
What do planet formation and badminton have in common?
Dust grains in protoplanetary disks align via the same aerodynamics as the sport. The birth of a planet starts with a microscopic grain floating in a protoplanetary disk, a swirli.....»»
New venomous reptile species from the Late Triassic unearthed in Arizona
A new species of small, venomous reptile, Microzemiotes sonselaensis, has been discovered in the Late Triassic Chinle Formation in northeastern Arizona. The findings, recently published in PeerJ, shed new light on the evolution of venomous feeding st.....»»
Microtubule formation mechanism sheds light on how cells build their internal skeleton
Inside every cell, a network of tiny filaments, called the microtubule cytoskeleton, helps maintain the cell's shape, allows it to divide, and transports vital materials from one part of the cell to another. The filaments that form this network, term.....»»
The government spent twice what it needed to on economic support during COVID, modeling shows
The independent inquiry into the government's COVID response is due to report on October 25......»»
