The study involved three groups of people and found significantly lower blood levels of plasma insulin-like growth factor 1 (IGF-1) in the low-protein diet group.
Research suggests that massive ancient carbon releases caused global warming 55 million years ago, with temperatures increasing by up to 9°F (5°C) in just 10,000 years. The findings imply high climate sensitivity to CO2 and contradict skepticism about the Earth's response to increased carbon dioxide emissions.

The Society for Cardiovascular Angiography and Interventions president urges the FDA to consider the benefits of drug-eluting stents when evaluating risks. The use of these devices has been linked to a slightly higher risk of late blood clot formation, but the benefits of preventing restenosis outweigh the risks.
Adults in consumer-driven plans spend large shares of their income on out-of-pocket costs and premiums. People with lower incomes are less likely to contribute to their accounts.
