In a first, researchers at Garvan Institute of Medical Research, Australia have identified a new DNA structure inside living human cells. Known as the intercalated motif (i-Motif), the newly identified structure looks poles apart from the iconic double helix structure everyone associates with DNA.
Muscular strength, measured by handgrip, is an indication of how sharp your brain is. The study which involved nearly half a million people also showed that the relationships were consistently strong in both people who were under the age of 55 and those over 55.
Researchers at Yale University in New Haven, CT, have discovered that intestinal bacteria in mice and humans can travel to other organs and evoke autoimmune response. But, administering antibiotic or vaccine that targets the bacteria can subdue this autoimmune reaction.
A gene is a segment of DNA that contains a set of instructions to make molecules that organisms need to survive. In a process called gene expression, these instructions are converted into some sort of product. And the product usually is either a protein or functional RNA. So what is gene expression? And, how do genes express themselves?
Without salt, your favourite foods such as french fries, potato chips, and chocolate chip cookies would all taste bland. And that’s because salt has lots of effects on flavor perception than just making things more salty. Many say a spoonful of sugar helps the medicine go down, but a pinch of salt, in fact, does the work better. How is that? And why does salt make food taste better?
Neuroscientists at University of California have identified 'anxiety cells' in the brain’s hippocampus. The finding, so far demonstrated with mice, could lead to better treatments for anxiety disorders in humans because the cells probably exist in humans, too, researchers say.
Neuroscientists at the University of California, Berkeley have claimed to track a thought racing across the brain. The finding confirms how the prefrontal cortex coordinates complex interactions between different regions in the brain - to help us act in response to what we perceive.
Ever felt tired and sluggish after eating sugar or a startling number of ginormous meals? That’s the effects of a sugar crash, which researchers at New Zealand have shown can impair cognitive performance – in a double-blind, placebo-controlled study.
Sodium is the predominant electrolyte in our body. It plays many important functions, such as maintaining proper fluid balance in the body, in assisting nerves conduction and in regulating blood pressure. But drinking too much water can disrupt its functions and has adverse effect in our health.
