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.
Study has found that the narrow diamond needles, could flex and stretch by as much as 9 percent without any breakage, then snap back to their original shape – much like rubber.

It left him wheelchair-bound and totally paralyzed.
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?
You certainly don’t want to miss this. Watch Morgan Freeman, Brian Cox, Carl Sagan and Sir David Attenborough calmly explaining our universe’s beautiful journey since the Big Bang - in this stunning 10 minute timelapse video.
Engineers at University of Tokyo have created tiny lights that can levitate using ultrasonic waves. Named Luciola for its resemblance to the firefly, the particle weighs 16.2 mg, has a diameter of 3.5 mm, and glows red – bright enough to illuminate text.
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.
