Control gene for developmental timing discovered

University of Alberta researchers have identified a key regulator that controls the speed of development in the fruit fly. When the researchers blocked the function of this regulator, animals sped up their rate of development ...

Parents' social problems affect their children -- even in birds

A recent study performed by Floriane Guibert and Cecilia Houdelier at the CNRS-University of Rennes in France, together with researchers at the INRA in Nouzilly, France and with Austrian scientists including Erich Mostl of ...

Mastermind steroid found in plants

Scientists have known for some time how important plant steroids called brassinosteroids are for regulating plant growth and development. But until now, they did not know how extensive their reach is. Now researchers, including ...

Hormones found to affect gene activity

(PhysOrg.com) -- Intermittent signaling by steroid hormones can affect the way genes are expressed in rodents, according to research by scientists at the University of Bristol and the National Cancer Institute (NCI), USA. ...

Study: Progesterone leads to inflammation

Scientists at Michigan State University have found exposure to the hormone progesterone activates genes that trigger inflammation in the mammary gland.

Worms control lifespan at high temperatures

The common research worm, C. elegans, is able to use heat-sensing nerve cells to not only regulate its response to hotter environments, but also to control the pace of its aging as a result of that heat, according to new ...
