Age and gut bacteria contribute to MS disease progression, according to Rutgers

A study by Rutgers University researchers suggests that gut bacteria at a young age contributes to the onset and progression of Multiple Sclerosis (MS). The study found that genetically engineered mice exposed to normal environment developed MS-like disease, highlighting the role of gut bacteria in triggering immune system changes.

Brain activity buffers against worsening anxiety

A new study by Duke University researchers found that people at-risk for anxiety were less likely to develop the disorder if they had higher activity in a region of the brain responsible for complex mental operations. Higher functioning dorsolateral prefrontal cortex may buffer against worsening anxiety.

'Wooden shoe' rather wear sneakers?

Western University researchers have found a high prevalence of bone lesions in the feet of 19th-Century Dutch farmers who wore wooden shoes, also known as klompen. The study suggests that these shoes were partly to blame for the injuries and trauma suffered by the farmers.

Production timings could stem illegal wildlife laundering

Researchers have developed a method to flag up potentially illegal wildlife trade by analyzing the growth rates of certain species. A study published in Biological Conservation has found that understanding these growth rates can help identify when an item is not yet legally available for sale, allowing authorities to act earlier.

New painkillers reduce overdose risk

Scientists at Scripps Research Institute developed new opioid pain relievers that are as potent as morphine but do not slow or stop breathing, reducing the risk of overdose. The compounds show a spectrum of bias between signaling pathways, providing an opportunity to expand the therapeutic window and administer drugs safely.

'Ion billiards' cue novel material synthesis method

Researchers at Hokkaido University have developed a novel material synthesis method that utilizes protons to introduce ions into host materials. This liquid-free process enables the homogenous introduction of various ions, such as lithium and sodium, into tantalum sulfide, maintaining its crystallinity.

Unlocking the secrets of Ebola

Scientists have identified two biomarkers that accurately predict patient survival in Ebola cases. The study analyzed blood samples from survivors and fatal cases, revealing distinct metabolic responses and immune-related molecules. These findings could improve treatment allocation and patient outcomes.

Reversing opioid overdose: Concentrated naloxone nasal spray as good as injection

A recent study published in Addiction has found that a concentrated 2mg intranasal naloxone spray delivers naloxone as effectively as the standard 0.4mg intramuscular injection over the critical first 15 minutes. The nasal spray maintains blood levels of naloxone more than twice as high as the IM levels for two hours after administration.

Study: For older women, every movement matters

A UB-led study of over 6,000 older women found that those who engaged in 30 minutes of light physical activity per day had a 12% lower risk of death. Moderate to vigorous activities also showed significant mortality benefits, extending to women with high and low functional ability.
