Ancient 'genomic parasites' spurred evolution of pregnancy in mammals
An international team of scientists has identified large-scale genetic changes that marked the evolution of pregnancy in mammals.
Did genetic links to modern maladies provide ancient benefits?
Psoriasis, a chronic skin condition, can cause rashes that itch and sting.
Tracking DNA helps scientists trace origins of genetic errors
Scientists have shed light on how naturally occurring mutations can be introduced into our DNA.
Evolution of marine mammals to water life converges in some genes
When marine mammals such as whales, dolphins, manatees and walruses moved from land to water, a series of physical abilities —– limbs adapted for swimming, less dense bones that make them more buoyant ...
Millions of GMO insects could be set loose in Florida Keys (Update)
Millions of genetically modified mosquitoes could be released in the Florida Keys if British researchers win approval to use the bugs against two extremely painful viral diseases.
Why is a dolphin not a cat? How repurposing non-coding elements in genome gave rise to great 'mammalian radiation'
New research shows how evolution has given rise to a rich diversity of species by repurposing functional elements shared by all mammals. Published in Cell by scientists at the European Bioinformatics Instit ...
Powerful tool promises to change the way scientists view proteins
Life scientists now have access to a publicly available web resource that streamlines and simplifies the process of gleaning insight from 3D protein structures. Known as Aquaria, the powerful tool is announced ...
Ribose-seq identifies and locates ribonucleotides in genomic DNA
Ribonucleotides, units of RNA, can become embedded in genomic DNA during processes such as DNA replication and repair, affecting the stability of the genome by contributing to DNA fragility and mutability. ...
Faster melon breeding thanks to smart combination of techniques
Smart new combinations of state-of-the-art molecular techniques mean that breeding programmes can be accelerated dramatically: it may soon take only two years instead of the current five or ten to develop ...
Bioengineers develop tool for reprogramming genetic code
Biology relies upon the precise activation of specific genes to work properly. If that sequence gets out of whack, or one gene turns on only partially, the outcome can often lead to a disease.
Genetic safety switches could help curb potential bioterror risks
The potential threat of bioterrorism using man-made biological organisms could be reduced, thanks to a new method developed by scientists.
Harnessing data from Nature's great evolutionary experiment
There are 3 billion letters in the human genome, and scientists have endlessly debated how many of them serve a functional purpose. There are those letters that encode genes, our hereditary information, and ...
Testing new biological plant protection products for effectiveness and practical feasibility
A naturally occurring fungus codenamed 'H39' might be the long-sought biological defence against the dreaded apple scab. "This fungus has not only been tested for its ability to fight the pathogen. The new ...
Breakthrough will help increase food security with better, more robust wheat varieties
After years of research efforts worldwide, researchers have finally identified a draft sequence of the bread wheat genome - an accomplishment that will lead to more robust and better wheat varieties in the ...
