Researchers have told an easy way to get fit - Watch sports.
Frontiers in Autonomic Neuroscience
Researchers have reported that watching other people exercise usually increases heart rate of the person along with some other physiological parameters as the person himself is doing exercise.
In the present study, researchers inserted very fine needles into an outer nerve of nine volunteers to record the electrical signals of nerve fibers di........ Read more »

Indian corn isn’t corn, it’s maize. But not all corn is maize, corn is actually an old word that denotes the major crop of any particular region. We use Indian corn as decoration, but its history is as a food stuff colors and all, an that history is getting longer, as a new study from Florida State shows that maize has been farmed for over 7000 years. The colors are most beautiful, including a newly breed variety called Carl’s Glass Gem corn. The spots of color were instrumenta........ Read more »

Priming is the idea that subtle cues and reminders can powerfully influence behavior. You hear about it in studies where women reminded of their gender perform less well on math problems. You may be skeptical of the power of priming on your own behavior. And certainly on the behavior of the hardened criminal. Alas, you […]

Implantable slimming aid
ETH-Zurich biotechnologists have constructed a genetic regulatory circuit from human components that monitors blood-fat levels. In response to excessive levels, it produces a messenger substance that signalises satiety to the body. Tests on obese mice reveal that this helps them to lose weight.___ ETH Zurich

Pain. Nobody particularly likes it, but with the pharmaceutical arsenal of pain relief medication at our disposal these days, many cases of pain can be tackled in one way or another.Tablets (before tablets) @ Wikipedia For those who watched the recent BBC series by the ever-intrepid Dr Michael Mosley titled 'Pain, pus and poison' on some of the important history behind the modern medical, chemical and pharmacy professions, pain was a feature of quite a few of the developments discussed........

Researchers have found that the happiest marriages are those where wives are able to quickly calm down during argument.
Emotions are most important things in the every aspect of life especially marital life. They can make or destroy relationship.

Explaining a rule or concept to yourself forces you to think deeply about it. Plenty of studies have shown this has benefits, both in terms of improving the understanding of relevant concepts and aiding the skill or process in question. Unfortunately, as Katherine McEldoon and her colleagues argue in their new paper, most of these studies are flawed because they failed to control for the extra time spent on self-explanation. So a typical study has compared, say, 30 minutes practice against 30 mi........ Read more »
