More than 100 years ago, paleontologist E. D. Cope of “Dinosaur Wars” fame found a few fragmentary bones of a reptile in the deserts of New Mexico. He named the reptile Typothorax. A century later, Typothorax — which belongs to a group of reptiles called aetosaurs — remained something of a mystery, known mainly from [...]
University of Alberta researchers have identified one of the body’s natural self-repair mechanisms that kick in after spinal cord injury which could lead to the development of more effective treatments.
The first new projections of future aircraft emissions in 10 years predict that carbon dioxide and other gases from air traffic will become a significant source of global warming as they double or triple by 2050.
A 17-year-long community study looking at symptoms of enlarged prostate in over 2,000 men age 40 to 79 years suggests that surgery for benign prostatic hyperplasia offers more relief from incontinence and obstruction symptoms than treatment from drug-based therapy, according to a new study.
Scientists in the U.S. and China have found that reforestation and afforestation — the creation of new forests — may lower the potential of forests for climate change lessening.

A new study finds that the imprint of European colonialism and imperialism is evident in the genetic makeup of today’s Hispanic/Latino American populations. Scientists discovered that Europeans, Native Americans, as well as West Africans brought to the US and Latin America by the trans-Atlantic slave trade, have influenced the genes of the current Hispanic/Latino populations. [...]
Scientists have identified the molecule adenosine as a central player in parlaying some of the effects of acupuncture in the body. Building on that knowledge, scientists were able to triple the beneficial effects of acupuncture in mice by adding a medication approved to treat leukemia in people.
Researchers have identified the genetic cause of an inherited condition that causes severe fetal abnormalities. The work should allow couples at risk of conceiving babies with the profoundly disabling Meckel-Gruber and Joubert syndromes to be identified beforehand through genetic screening.

Researchers have found that pancreatic cancer patients who have circulating tumor cells tend to have worse outcomes than patients without circulating tumor cells. Additionally, the team has uncovered evidence that not all circulating tumor cells are the same, and some may predict worse outcomes than others.
