Rare form of active 'jumping genes' found in mammals

Much of the DNA that makes up our genomes can be traced back to strange rogue sequences known as transposable elements, or jumping genes, which are largely idle in mammals. But Johns Hopkins researchers report they have identified ...

Scientists decode watermelon genome

Are juicier, sweeter, more disease-resistant watermelons on the way? An international consortium of more than 60 scientists from the United States, China, and Europe has published the genome sequence of watermelon (Citrullus ...

Scientists discover new method of gene identification

Scientists studying the genes and proteins of human cells infected with a common cold virus have identified a new gene identification technique that could increase the genetic information we hold on animals by around 70 to ...

MicroRNAs in plants: Regulation of the regulator

MicroRNAs are essential regulators of the genetic program in multicellular organisms. Because of their potent effects, the production of these small regulators has itself to be tightly controlled. That is the key finding ...

A new computational method for timing the tree of life

With its deeply embedded roots, sturdy trunk and dense profusion of branches, the Tree of Life is a structure of nearly unfathomable complexity and beauty. While major strides have been made to establish the evolutionary ...

Are animal traits the result of behavioral epigenetics?

A plant that is unremarkable in one environment becomes an invasive species in another, pushing through house foundations and sprouting up through roads. A house sparrow that's a perfectly charming resident of the English ...
