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 ...

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. ...

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 ...

The secret life of frogs

(PhysOrg.com) -- University of Notre Dame biologist Sunny Boyd's research is a little like "Match.com" for amphibians. Say you're a female tree frog looking for a mate--how do you choose among a number of potential suitors?

In defence of woodlice and their complicated sex lives

Lots of adults dislike woodlice. Some are physically revolted by them. But this distaste is cultural rather than innate since most small children are well-disposed towards woodlice and happy to handle them. Some people even ...

Fish are being increasingly exposed to endocrine disrupters

Microplastics, owing to their chemical properties, can carry micropollutants into a fish's digestive system where they are subsequently released through the action of its gastric and intestinal fluids. EPFL scientists, working ...

Efficient removal of steroid hormones from water

Micropollutants contaminate the water worldwide. Among them are steroid hormones that cannot be eliminated efficiently by conventional processes. Researchers of Karlsruhe Institute of Technology (KIT) have now developed an ...
