We know that in addition to making great companions, dogs assist people in various ways. Herding, bomb/drug detection and working as service dogs are just a few examples. Dogs provide helpful assistance you may not know about in several other ways. How Do Dogs Help Humans?With an innate ability to adapt and learn, dogs have taken on diverse tasks that range from safeguarding our lives on beaches to alerting us to impending health crises. These extraordinary canines have not only secured a s ...read more
Paleontologists in Thailand recently unveiled the discovery of a new dinosaur, Minimocursor phunoiensis, or “smallest runner” in Latin. The small, bipedal plant-eater likely ran in herds and occupied a lower rung on its local food chain. It would have dodged much larger predators, including the metriacanthosauridae theropods, predecessors to Tyrannosaurus Rex.The skeleton is one of the best-preserved ever recovered from Southeast Asia, where it was found in the Kalasin province in northeaste ...read more
A 46,000-year-old gopher hole in Siberia served as a time capsule for some very old plant material and a small nematode roundworm, which was later revived, according to a new study.Researchers from the Soil Cryology Lab in Russia extracted the contents of the hole from Duvanny Yar outcrop in Siberia, a sheer wall of prehistoric sediments. Ancient rodents had dug the burrow, about 10 inches wide, during the Last Ice Age, and cold temperatures had since frozen it into permafrost that never thaws.T ...read more
In a famous scene from “Jurassic Park,” ranger Robert Muldoon aims his sights at a velociraptor, only to be ambushed by another female velociraptor — a “clever girl,” as he says.Partly because of iconic films like this, pack hunting among theropods (two-legged, meat-eating dinosaurs, including velociraptor and many others) is well ingrained in the public imagination. But researchers are at loggerheads over whether these extinct hunters were ever actually smart enough to work together t ...read more
The heart is a complex organ with a simple purpose – pump blood in and pump it out again. It does this through an interconnected network of rectangular heart cells called cardiomyocytes that pump blood into the top of the heart (through the atria) and out through the ventricles at the bottom. Pacemaker cells on the heart keep it ticking away at 60 to 100 beats per minute, depending on the person’s basal heart rate.Because of the heart’s complexity, attempts to 3D print a model version to u ...read more
