Most mammals have a greater life expectancy in zoos

Science Daily - Mon, 07/11/2016 - 4:26pm
Life in the wild harbors the risk of predation, food shortages, harsh climates, and intense competition. Zoo animals, by contrast, are protected from these dangers. Researchers were part of an international team that studied over 50 mammalian species to determine whether the animals live longer in zoos than in the wild.

A giant predatory lizard swam in Antarctic seas near the end of the dinosaur age

Science Daily - Mon, 07/11/2016 - 4:24pm
Kaikaifilu is a new species of giant sea lizard (mosasaur) discovered in 66-million-year-old rocks of Antarctica. At about 10 meters long, it is the largest known top marine predator from this continent. It lived near the end of the dinosaur age, when Antarctica was a much warmer ecosystem, and fed on filter-feeding marine reptiles.

Do second opinions matter in prostate cancer care?

Science Daily - Mon, 07/11/2016 - 4:24pm
Many men with prostate cancer obtain second opinions from urologists before starting treatment, but surprisingly, second opinions are not associated with changes in treatment choice or improvements in perceived quality of prostate cancer care. These findings also explore motivations for seeking second opinions, and suggest that second opinions may not reduce overtreatment in prostate cancer.

Andeans with altitude sickness produce massive amounts of red blood cells

Science Daily - Mon, 07/11/2016 - 4:03pm
To better understand why some people adapt well to life at high altitude while others don’t, researchers studied red blood cells derived from representatives of both groups living in the Andes Mountains. The study reveals that high-altitude, low-oxygen dwellers prone to chronic mountain sickness produce massive amounts of red blood cells thanks to overproduction of the enzyme SENP1.
