Researchers describe the interstitium as an interconnected network of fluid-filled spaces in connective tissue, revealing a third circulatory system that links skin, fascia, and organs; this could explain acupuncture's mechanisms, influence fat biology and inflammatory bowel disease, and shed light on how cancer spreads, with potential new therapeutic targets.
A population-based study using Israel’s National Birth Registry found that congenital malformations were more common in children later diagnosed with autism spectrum disorder (ASD) than in neurotypical peers, with circulatory and urogenital anomalies most prevalent. Sex-specific patterns emerged: genital malformations were more frequent in boys with ASD, while non-genitourinary (primarily circulatory) malformations were more common in girls with ASD; authors suggest prenatal androgens may influence development but acknowledge limitations like diagnostic changes and potential survival bias. Congenital malformations could serve as early markers for ASD risk.
Scientists have discovered that basking sharks, typically considered cold-blooded, exhibit elevated body temperatures while swimming, challenging our understanding of fish physiology. Previously, warm-bloodedness was thought to be limited to apex predators, but this study shows that it can also occur in large, passive-feeders like basking sharks. The sharks' ability to maintain higher blood pressure and blood flow, facilitated by compact muscle around their hearts, may allow them to migrate and feed more efficiently in colder waters. The reasons behind their warm-bloodedness and its advantages are still unclear, highlighting the need for further research on shark species for effective conservation strategies.
