Why eukaryotes, not bacteria, evolved complex multicellularity
Prokaryotic single-celled organisms, the ancestors of modern-day bacteria and archaea, are the most ancient form of life on our planet, first appearing roughly 3.5 billion years ago. The first eukaryotic cells appeared around 1–1.5 billion years la.....»»
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.....»»
Evolved in the lab, found in nature: Uncovering hidden pH sensing abilities in microbial cultures
In a study led by Sarah Worthan, Ph.D., a postdoctoral researcher in the Behringer Lab at Vanderbilt University, scientists have successfully evolved microbial cultures that possess the ability to sense pH changes, enabling rapid responses to environ.....»»
Research proposes theory to model interplay of personal and social beliefs
The beliefs we hold develop from a complex dance between our internal and external lives. Our personal-level cognition and our relationships with others work in concert to shape our views of the world and influence how likely we are to update those v.....»»
Independent origins of frog glue and its role in predator evasion
Skin-secreted adhesives, or glues, are highly effective defense adaptations that have evolved recurrently in a small number of amphibians. From an ecological standpoint, this rapidly solidifying material—essentially, a sticky slime—encumbers the.....»»

Forescout announced its new SaaS Operational Technologies (OT) solution. Forescout for OT Security is a security solution that allows organizations to secure complex, heterogeneous OT, IoT/IoMT, and IT environments whether they are fully in cloud, co.....»»
Reducing floodplain development doesn"t need to be complex, say researchers
A paper, titled "How local governments avoid floodplain development through consistent implementation of routine municipal ordinances, plans, and programs," published in Oxford Open Climate Change uncovers evidence suggesting that, contrary to expect.....»»
Bioengineers create new substrate to study wood-decomposing enzyme
Researchers want to transform the natural and abundant resource wood into useful materials, and central to that is a molecular machine found in fungi that decomposes the complex raw material into its basic components......»»
Greenhouse gains: Cucumbers genetic upgrade through innovative pollen tech
Genetic modification in horticultural crops, particularly within the Cucurbitaceae family, is often hindered by complex tissue culture requirements and environmental pressures such as climate change. Traditional transformation techniques, like Agroba.....»»
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.....»»
Ocean waves grow way beyond known limits, new research finds
Scientists have discovered that ocean waves may become far more extreme and complex than previously imagined......»»
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.....»»
Zirconium metals under extreme conditions found to deform in surprisingly complex ways
Materials are crucial to modern technology, especially those used in extreme environments like nuclear energy systems and military applications. These materials need to withstand intense pressure, temperature and corrosion. Understanding their lattic.....»»
Computational tool can pinpoint causal relationships from complex biological data
Researchers have developed a tool that provides new insights into cause-and-effect relationships between cells and how these change over time......»»
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......»»
Complex dynamics of 2024 M 7.6 Noto Hanto earthquake in Japan—the long-lasting swarm and its immediate foreshocks
A study published in the journal Earthquake Research Advances sheds light on the relationship between the 2024 magnitude 7.6 Noto Hanto earthquake and a sizable earthquake swarm that began beneath Japan's Noto Peninsula in November 2020......»»
Pinpointing the key size for rapid tropical cyclone intensification
Accurately predicting how rapidly tropical cyclones (TCs) will intensify is a significant challenge due to the complex processes involved. Limited observations show that smaller TCs tend to intensify faster, suggesting a simple linear relationship be.....»»
