The common belief that baby rattlesnakes are more dangerous than adults has been overturned by a new study from Loma Linda University. After considering the history and spread of the myth, researchers concluded that bites from adult rattlesnakes are generally more dangerous because adult rattlesnakes carry and inject much larger amounts of venom. The study also disproves the widely repeated claim that baby rattlesnakes cannot control the amount of venom they release and therefore inject all of their venom into their bite. Researchers say this misconception has serious real-world implications. The study said the false beliefs led to “negative outcomes,…
From increased activity and aggression in animals to changes in brain responses in humans, this review shows how irritability research can shed light on why irritability is clinically impaired. Review: Frustrated non-rewards: A heterogeneous exploration to study the brain mechanisms of irritation. Image credit: Roman Samborskyi / Shutterstock In a recent study published in the journal translational psychiatryresearchers reviewed research on frustration in humans and animals and discussed opportunities for cross-species research. Recently, there has been an increase in clinical research on irritability, especially among young people. Irritability is a tendency toward anger that is normal at low levels but…
Some people are sensitive to low-frequency noise from ventilation systems, heat pumps, wind turbines, transformers, etc. why is that? The brain perceives low-frequency sounds quite differently than other sounds. Perhaps that’s why some people react to them even more. Experts call sounds below 16 Hz infrasound. This is a sound that is often thought to be impossible to hear. But that’s not the case. Humans can actually perceive infrasound if the sound level is high enough. ” Carlos Jurado, Postdoctoral Researcher, Department of Neurology and Exercise Sciences, Norwegian University of Science and Technology (NTNU) Some are sensitive to low frequency…
New and previously unpublished clinical data were presented today at ISSCR 2026 showing that transplanted human neural progenitor cells survive for at least 1 year and maintain a favorable safety profile after subretinal transplantation in patients with retinitis pigmentosa (RP). Retinitis pigmentosa is a group of inherited retinal diseases that cause progressive vision loss, and there is currently no treatment for most patients. Developing mutation-specific gene therapies remains challenging because thousands of different genetic mutations can cause the disease. Cell-based therapies offer the potential for gene-independent approaches that may benefit a broader patient population. A Phase 1/2a clinical study funded…
A carefully balanced diet of plant- and fish-based, low-protein, amino acid foods found in foods such as eggs, meat and dairy products can help mice stay healthy as they age, according to a new study from the University of Southern California. This diet increased the healthy lifespan, reduced body fat, and decreased frailty in older mice. The survey results are cell metabolismbacked by an analysis of dietary and health data from more than 200,000 people conducted by researchers at USC, the University of Toronto, and Harvard University. People who followed a more plant-based dietary pattern were also shown to have…
The International Society for Stem Cell Research (ISSCR) today announced that it will present new clinical data from the STEM-PD Phase I/II clinical trial at the ISSCR 2026 Annual Meeting. This study reports 12-month results evaluating a cryopreserved off-the-shelf dopaminergic progenitor cell product derived from human pluripotent stem cells for the treatment of Parkinson’s disease. The results of this study provide new insights into the safety, feasibility, and biological activity of stem cell-derived dopaminergic cell transplantation in Parkinson’s disease patients and represent another important step in the clinical application of regenerative medicine for neurodegenerative diseases. “These data represent the culmination…
Ongoing research has revealed that polyfloral honey is a promising candidate for protecting human skin cells from premature aging and UV-induced cell damage, with potential for future clinical and cosmetic applications. Honey is already well known in the medical and cosmetic industries for its antioxidant, antibacterial, anti-inflammatory and wound-healing properties, and sterile medical products derived from honey already exist in the form of bandages, gels and ointments for burns and difficult-to-heal wounds. “I have always been interested in the fact that certain honeys, such as Manuka honey, are used for medical-grade applications. My background in medical biology and my personal…
Physicists at the University of Birmingham have created a laboratory ‘mini-universe’ that will bring scientists one step closer to answering one of the biggest questions in physics: ‘What is time?’ In a study published in physical review studyProfessor Giovanni Barontini has demonstrated that it is possible to measure the passage of time without relying on clocks. Instead, this experiment shows that versions of time can emerge naturally from the behavior of the quantum system itself. Why some physicists think time is not fundamental Some theories of modern physics suggest that time may not exist as a built-in feature of the…
Approximately one in five women will experience depression or anxiety during pregnancy or within the first year after giving birth. Without treatment, mothers with these conditions are at increased risk for birth complications, poor overall health, impaired bonding and nurturing of the infant, and death by suicide. But a new treatment moving through the Food and Drug Administration’s clinical trial process could be the key to treating, and even curing, depression and anxiety in postpartum people. It is a newly named psychedelic, rubesirocin. It works like psilocin, the psychoactive chemical in psilocybin mushrooms. Unlike existing treatments, it may be able…
A tiny spider with a bright red smile on its back has surprised scientists by reappearing thousands of miles from where a famous relative was thought to live. For over 100 years, the happy-faced spider was believed to exist only in Hawaii, making it one of the most famous and rare arachnids in the world. Now, researchers from the Forest Research Institute and the Regional Museum of Natural History have identified a new species in the mountains of Uttarakhand, India. They named it because of its striking resemblance to the Hawaiian species Teridion Himalayanaor the Himalayan Happy Face Spider. Accidental…
