The word "cholesterol" is directly linked in most people's minds with high-fat foods, worrying blood test results, and cardiovascular diseases. However, despite its bad reputation, cholesterol is...
View ArticleHow immune cells use steroids
Researchers at the European Bioinformatics Institute (EMBL-EBI) and the Wellcome Trust Sanger Institute have discovered that some immune cells turn themselves off by producing a steroid. The findings,...
View ArticleBrain steroids make good dads
Testosterone in males is generally associated with aggression and definitely not with good parenting. Insights from a highly social fish can help understand how other androgenic steroids, like...
View ArticleHow steroid hormones enable plants to grow
Plants can adapt extremely quickly to changes in their environment. Hormones, chemical messengers that are activated in direct response to light and temperature stimuli help them achieve this. Plant...
View ArticleNo junk: Long RNA mimics DNA, restrains hormone responses
It arises from what scientists previously described as "junk DNA" or "the dark matter of the genome," but this gene is definitely not junk.
View ArticleHow rodents bulk up for winter without going nuts
When Arctic ground squirrels need to bulk up for winter, they get a boost from an enormous spike in the levels of steroids in their blood. So why doesn't it lead to 'roid rage?
View ArticleBaleen hormones increase understanding of bowhead whale reproduction
Wild animals provide a unique challenge for physiologists because they are difficult to capture and monitor in their natural habitats. As a result, scientists are increasingly learning about organisms...
View ArticleFirst-ever view of protein structure may lead to better anxiety drugs
When new medicines are invented, the drug may hit the intended target and nullify the symptoms, but nailing a bull's eye - one that produces zero side effects - can be quite elusive.
View ArticleHormone sensitive gene regulation in seasonal singing birds
Nature lovers are fascinated by the increasing number of singing birds when spring is approaching. Scientists also take advantage of this seasonal phenomenon because they are able to investigate the...
View ArticleGolden vehicle for drug delivery has hidden costs
One of the biggest ideas in treating disease involves material so small it isn't even visible. Miniscule gold particles – the size of several atoms – are being touted as vehicles to send drugs exactly...
View ArticleA new timetable of eukaryotic evolution
Contaminated samples have evidently created some confusion in the timetable of life. On the basis of ultra-clean analyses, an international team, including scientists from the Max Planck Institute for...
View ArticleConventional 'free diffusion' model of steroid hormone release should be...
Steroid hormones - hormones such as testosterone and estradiol - control various aspects of animal biology and are crucial for the proper functioning of the body. Produced and secreted by endocrine...
View ArticleAncient protein flexibility can drive 'new' functions
A mechanism by which stress hormones inhibit the immune system, which appeared to be relatively new in evolution, may actually be hundreds of millions of years old.
View ArticleExpression of a "Ouija Board" protein that can summon "monster" genes
Steroid hormones are biologically active substances that play important roles in the development and sexual maturation of individuals, as well as in maintaining homeostasis, regardless of species....
View Article'Female traders can reduce market crashes', research says
Researchers in the Department of Economics at the University of Leicester have found that male traders on average earn less than their female counterparts but, as they were more comfortable taking...
View ArticleUncovering pathway that makes steroid hormones fast and efficient
How can the group of chemicals known as steroid hormones cause almost instantaneous changes in your body, like hydrocortisone inhalers with asthma? In an interview with UC Science Today, UC Berkeley...
