Is the relationship between diet, intestinal bacteria and cells key to preventing systemic inflammation?
Mice fed a diet high in fat, cholesterol and calories, akin to the Western diet, had higher measures of blood lipids associated with elevated levels of inflammation, a new study finds......»»
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.....»»
First-of-its kind tool allows scientists to manipulate cells without touching them
When studying the spread of cancer or the behavior of a virus like the one that causes COVID-19, the irony is that working with these harmful pathogens requires gentleness. Especially in the case of COVID, the particles do not survive well when makin.....»»
The relationship between emotions and economic decision-making differs across countries, multi-national analysis finds
When making economic decisions, humans can be driven by various factors, including their goals and emotions. Past studies have hypothesized that emotions play a crucial role in economic decisions, particularly those that involve risk or trade-offs be.....»»
Plant pathogen battle: A tomato protein"s dual role in defense and susceptibility
Tomatoes, a staple crop worldwide, are increasingly threatened by biotic stressors such as viruses, fungi, and bacteria, with the effects worsening under climate change. These challenges lead to reduced yields and compromised nutritional quality, hig.....»»
Redwood Materials signs deal to recycle BMW’s EV batteries in the US
The automaker will use recycled materials from Redwood in its American-made EVs. Enlarge / BMW is moving to cylindrical cells for its sixth-generation EV powertrain, which debuts in the Neue Klasse. And now it has a recycling par.....»»
Silencing in action: How cells "repress" genomic remnants of ancient viruses
Researchers have identified key cellular control sites that regulate gene expression and prevent the activation of "cryptic" genomic regions, including ancient viral sequences......»»
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.....»»
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.....»»
What Is Sickle Cell Disease?
You have around 35 trillion red blood cells moving around your body at all times. Typically they are rounded and flexible. What happens when they aren’t?.....»»
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......»»
Scientists decipher the energy patterns in our cells
Our cells harness energy for essential functions such as division, wound healing, and our immune response to diseases including cancer. But until now, the mechanics of how that energy affects cell behavior—and how this relates to health outcomes—.....»»
Study sheds light on trade-off between noise and power in nanoscale heat engines
Thanks to nanoscale devices as small as human cells, researchers can create groundbreaking material properties, leading to smaller, faster, and more energy-efficient electronics. However, to fully unlock the potential of nanotechnology, addressing no.....»»
"Marine identity" can help restore the ocean, say researchers
People's deep connection with the ocean—their "marine identity"—can help us reset society's relationship with the seas, new research led by Dr. Pamela Buchan, from the University of Exeter, suggests......»»
Optogenetic control reveals collective cell behavior
New research led by the Institute for Bioengineering of Catalonia (IBEC) has studied the migratory movement of groups of cells using light control. The results show that there is no leader cell that directs the collective movement, as previously thou.....»»
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......»»
Researchers develop new method for delivering RNA and drugs into cells
Researchers at the University of Toronto and its hospital partners have developed a method for co-delivering therapeutic RNA and potent drugs directly into cells, potentially leading to a more effective treatment of diseases......»»
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.....»»
Trimetallic-based nanocarriers method shows promise for visualized idiopathic pulmonary fibrosis therapy
A research group from Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS) developed a novel method for idiopathic pulmonary fibrosis (IPF) therapy by transplanting mesenchymal stem cells (MSCs), w.....»»
Paleontologists find omnivorous ancestor of the giant panda, revealing it was not always just a bamboo eater
The Hammerschmiede fossil site in southern Germany has yielded finds from about 11.5 million years ago that have rewritten evolutionary history. The sole species of bear discovered to date at the site was a relative of the giant panda. Its diet, howe.....»»
