Risky High Life: Mountain creatures prove extra-vulnerable
Some of the species hardest hit by climate change will be those living in particular mountain highlands.

Healed scars tag T. rex as predator
Healed wounds on the fossil skull of a Triceratops—wounds that match the size and shape of those that would be made by Tyrannosaurus rex—are a strong sign that the tooth scrapes are a result of attempted predation, not scavenging.

Flightless Feathered Friends
New finds of fossil penguins, as well as analyses of the characteristics and DNA of living penguins, are shedding light on the evolution of these flightless birds.

One-Celled Socialites
A wave of research on the social lives of bacteria offers insights into the evolution of cooperation and may lead to medical breakthroughs that neutralize virulent bacterial strains.

Ancient atmosphere was productive
New laboratory experiments suggest that extra carbon dioxide in the atmosphere in the era just before the dinosaurs went extinct may have boosted plant productivity to at least three times that found in today’s ecosystems.

Role of gastroliths in digestion questioned
New analyses of the gastroliths in ostriches are casting doubt on the theory that large, plant-eating dinosaurs swallowed stones to grind up tough vegetation and thereby aid their digestion.
