Moving to Cities is Linked to Diabetes in Developing World

December 19, 2014 7:00 am | by Endocrine Society | News | Comments

One factor that can raise a person’s risk of developing diabetes and other metabolic problems is chronic exposure to the stress hormone cortisol. Cortisol can counteract insulin, the hormone that regulates blood sugar, and slow the body’s production of it. As people in developing nations relocate from rural areas to cities, the increased stress is affecting their hormone levels and making them more susceptible to diabetes.

Expectant Fathers Have Changing Hormones, Too

December 19, 2014 7:00 am | by Univ. of Michigan | News | Comments

Impending fatherhood can lower two hormones— testosterone and estradiol— for men, even before their babies are born, according to a study. Other studies indicate that men's hormones change once they become fathers, and there is some evidence that this is a function of a decline after the child's birth. This is the first to show that the decline may begin even earlier, during the transition to fatherhood.

Ibuprofen Linked to Long Lifespan in Several Species

December 19, 2014 7:00 am | by Texas A&M AgriLife Research | News | Comments

Ibuprofen, a common over-the-counter drug worldwide, added to the healthy lifespan of yeast, worms and flies in a recent study. The treatment, given at doses comparable to the recommended human dose, added about 15 percent more to the species lives. In humans, that would be equivalent to another dozen or so years of healthy living.

Crows Are Even Smarter than Thought

December 18, 2014 2:00 pm | by Univ. of Iowa | News | Comments

Crows have long been heralded for their high intelligence— they can remember faces, use tools and communicate in sophisticated ways. Now a study has found crows also have the brain power to solve higher-order, relational-matching tasks, and they can do so spontaneously. That means crows join humans, apes and monkeys in exhibiting advanced relational thinking.

Earth May Have Made Its Own Water

December 18, 2014 7:00 am | by The Ohio State Univ. | News | Comments

A new study is helping to answer a longstanding question that has recently moved to the forefront of earth science: Did our planet make its own water through geologic processes, or did water come to us via icy comets from the far reaches of the solar system? The answer is likely “both.” And the same amount of water that currently fills the Pacific Ocean could be buried deep inside the planet right now.
