Biosynthesis pathway of a new DNA nucleobase elucidated
DNA is composed of nucleobases represented by the letters A, T, G and C. They form the basis of the genetic code and are present in all living beings. But in a bacteriophage, another base, represented by the letter Z, exists. This exception, the only.....»»
New study says dogs can ‘see’ with their noses
Dogs have always been well known for their ability to identify and track scents. A new study suggests that extensive connections within the dog’s olfactory pathway are responsible for this. Further, the study posits that dogs can see with their nos.....»»

The mechanism of trichome formation in response to stress-induced jasmonic acid signaling in tomatoes
As a plant stress hormone, jasmonic acid (JA) plays an important role in mediating the resistance of plants against mechanical stress, pest attack, and pathogenic infection. The biosynthesis of JA and the expression of JA signaling genes are activa.....»»
Origins of the Avars elucidated with ancient DNA
Less known than Attila's Huns, the Avars were their more successful successors. They ruled much of Central and Eastern Europe for almost 250 years. We know that they came from Central Asia in the sixth century CE, but ancient authors as well as moder.....»»
