Callimico monkeys eat fungi during the dry season, a trait shared by no other tropical primate species. They also exhibit a different reproductive strategy than other small New World monkeys, giving birth to single offspring twice annually.
Research suggests that sloths expel larger particles more efficiently than expected, potentially due to unique digestive adaptations. This study challenges the conventional wisdom on sloth behavior and highlights the importance of considering the interplay between resting posture, digestive anatomy, and ingesta characteristics.
A recent Stanford Medicine study shows that an automatic CPR device, AutoPulse, can restore blood flow and pressure more effectively than manual compressions. The device restored blood flow and returned hearts to normal condition in 73% of treated animals.
Researchers have found that adult rat hearts contain cardiac progenitor cells capable of repairing damaged tissue. The study, published in Cell, used these cells to regenerate new myocytes and other functional cells in ischemic hearts.
Research shows that omega-3 fish oils stored in heart cells can prevent sudden cardiac death and fatal arrhythmias. Studies found a 29% reduction in deaths among men who ate fish at least twice a week, attributed to fewer fatal arrhythmias.
Researchers found that desflurane improved neurologic outcomes in piglets undergoing low-flow cardiopulmonary bypass, reducing brain injury and abnormal heart rhythms. The study suggests desflurane may protect the brain and nervous system during heart surgery, improving quality of life for survivors.
The study reveals that female mice develop cardiac hypertrophy when estrogen is blocked, mimicking human conditions. The discovery could lead to a better understanding of the molecular signals causing heart enlargement and potential ways to prevent or reverse it.
Researchers argue that sauropods, like Barosaurus, required a horizontal neck to function on land due to heart size and metabolic rates. This finding contradicts the common depiction of long-necked dinosaurs raising their heads to browse from trees.
Researchers have discovered a dinosaur fossil with a four-chambered heart, similar to those of birds and mammals. The discovery suggests that the dinosaur was warm-blooded, with a high metabolism, and may have had a more complex circulatory system than previously thought.
A team of scientists has discovered a 66-million-year-old Thescelosaurus with a complete fossilized heart, suggesting the dinosaur's circulatory system was more advanced than that of reptiles. The finding supports the hypothesis that dinosaurs were warm-blooded and could have had metabolic rates higher than typical reptiles.
Researchers at Kanagawa University have invented a technique to store human organs for up to 10 days using the natural preservative trehalose. The method involves flushing organs with trehalose solution and storing them in silica gel, allowing for longer-term preservation without significant tissue damage.
Researchers at Duke University have found that transplanted skeletal muscle cells can mimic heart muscle, significantly boosting the ability of damaged hearts to contract. The therapy has the potential to augment current treatments and prevent further damage.
