Nasal Vaccine for COVID-19 Shows Promise in Stopping Transmission, Animal Research Reveals

A nasal COVID-19 vaccine blocks transmission of the virus, according to an animal study. The findings suggest that vaccines delivered directly to the nose or mouth could play a critical role in containing the spread of respiratory infections. The lightning-fast development of COVID-19 vaccines just months after the virus appeared was a triumph of modern

Crafting Models: Understanding Belief Dynamics Through Engaging Analogies

Researchers who study belief dynamics often use analogies to understand and model the complex cognitive-social systems that underlie why we believe the things we do and how those beliefs can change over time. Ideas can be transmitted like a virus, for instance, 'infecting' a population as they spread from person to person. We might be

Innovative Defense: How Pancreatic Cells in Mice Shield Themselves from Inflammation

The results of the new study could have significant implications for understanding diabetes. Researchers from the University of Cologne have revealed a mechanism protecting pancreatic β-cells, which are crucial for insulin production from inflammatory cell death. The study investigated the role of receptor-interacting protein kinase 1 (RIPK1) in regulating β-cell survival. Typically, this protein controls

How Human Stress Scents Influence Dog Emotions and Pessimistic Choices

Dogs experience emotional contagion from the smell of human stress, leading them to make more 'pessimistic' choices, new research finds. Researchers tested how human stress odors affect dogs' learning and emotional state.

Breakthrough Discovery: New Antidote for Cobra Bites Unveiled

Cobras kill thousands of people a year worldwide and current antivenom treatment is expensive and does not effectively treat the necrosis of the flesh where the bite occurs. Using CRISPR technology, scientists have discovered a commonly available drug can stop the necrosis, potentially saving thousands of lives a year. Scientists at the University of Sydney

Unlocking Longevity: How Switching Off Inflammatory Proteins Prolongs Lifespan in Mice

Scientists have discovered that 'switching off' a protein called IL-11 can significantly increase the healthy lifespan of mice by almost 25 percent. Scientists at the Medical Research Council Laboratory of Medical Science and Imperial College London have discovered that 'switching off' a protein called IL-11 can significantly increase the healthy lifespan of mice by almost

Uncovering Internal World Models: Humans, Animals, and AI Explained

Researchers have developed a new formal description of internal world models, thereby enabling interdisciplinary research. Internal world models help to make predictions about new situations based on previous experience and to help find one's bearings. The new formalized view helps to compare world models of humans, animals and AI and to eliminate deficits. A team

Electrifying Innovation: Soft, Stretchy ‘Jelly Batteries’ Inspired by Electric Eels

Researchers have developed soft, stretchable 'jelly batteries' that could be used for wearable devices or soft robotics, or even implanted in the brain to deliver drugs or treat conditions such as epilepsy.

Breakthrough HIV-1 Treatment from Llamas: Deactivating Wide Range of Strains | Novel Antibody Discovery

Biology researchers have developed a new antibody therapy that can neutralize a wide variety of HIV-1 strains. They found success in an unlikely source -- llamas. A research team at Georgia State University has developed tiny, potent molecules that are capable of targeting hidden strains of HIV. The source? Antibody genes from llama DNA. The

Cuttlefish Psychology: False Memories in Cephalopods

During an event, details like what you saw, smelled, and felt aren't stored as a single memory. Rather, they are encoded and stored in your brain separately. To retrieve that memory, those pieces must get put back together. When that doesn't happen in the right way or details are distorted, it can lead to the

Fat Cats on a Diet: Understanding Obesity in Humans | Health Insights

Pet cats may be excellent animal models for the study of obesity origins and treatment in humans, a new study of feline gut microbes suggests -- and both species would likely get healthier in the research process, scientists say.

E. coli Variant: Antimicrobial Resistance in Dogs and Humans

Researchers studying antimicrobial-resistant E. coli -- the leading cause of human death due to antimicrobial resistance worldwide -- have identified a mechanism in dogs that may render multiple antibiotic classes ineffective.

Revolutionary Gene Editing Restores Hearing in Deaf Mice: A Breakthrough in Inherited Deafness Treatment

Researchers have used gene editing to restore hearing in adult mice with a type of inherited hearing loss. They showed that shutting down a damaged copy of a gene called a microRNA (miRNA) enabled the animals to regain hearing. The approach may eventually lead to potential treatments for inherited hearing loss in people. Researchers have

Uncovering the Risks: H5N1 and Raw Cow’s Milk Transmission in Mammals

While H5N1 avian influenza virus taken from infected cow's milk makes mice and ferrets sick when dripped into their noses, airborne transmission of the virus between ferrets -- a common model for human transmission -- appears to be limited. These and other new findings about the strain of H5N1 circulating among North American dairy cattle
