Dinosaurs engaged in mating behavior similar to modern birds, leaving fossil evidence behind in 100-million year old rocks, according to new research. Paleontologist Martin Lockley of the University of Colorado Denver led a research team that discovered what he called large “scrapes” in prehistoric Dakota sandstone in western Colorado.
An ape thought to be the largest in Earth’s history died out because it couldn’t adapt or get enough food in a changing landscape about 100,000 years ago, scientists argue in a new study. The giant ape Gigantopithecus weighed an estimated 200 to 500 kg, or 400 to 1,111 pounds. That’s up to three times heavier than the largest living species of gorilla, the Eastern lowland gorilla.
Chemists say they have found a way to make a DNA-like molecule assemble itself in a pond-like setting—potentially suggesting a key step in how life originated. The researchers actually worked with a simpler molecule, called pre-RNA. It’s hypothesized to have eventually evolved into DNA—one stopping point along the way having been the creation of a third substance, RNA, still used in the body to translate the code inscribed in DNA.

Scientists say they have obtained promising results from a Phase 2 trial of a treatment against the decline in muscle mass and power associated with aging. The “proof-of-concept” trial examined the prospects for a myostatin antibody, a drug designed to counter the effects of a protein that scientists see as a culprit in muscle decline.
