The ethics of resurrecting extinct species
(Phys.org) —At some point, scientists may be able to bring back extinct animals, and perhaps early humans, raising questions of ethics and environmental disruption.
Novel way plants pass traits to next generation found: Inheritance behavior in corn breaks accepted rules of genetics
New research explains how certain traits can pass down from one generation to the next – at least in plants – without following the accepted rules of genetics.
DNA tests show Lonesome George may not have been last of his species
(Phys.org)—When the giant tortoise Lonesome George died this summer, conservationists from around the world mourned the extinction his species. However, a genetic analysis by Yale University researchers ...
For the rooster, size matters—Pleiotropic genes affect comb size and egg production
A lone rooster sees a lot of all the hens in the flock, but the hen with the largest comb gets a bigger dose of sperm - and thus more chicks. This sounds natural, but behind all this is humanity's hunger ...
UC research examines eugenics past and present, driven by race, class, economics
the science of improving the human population via selective breeding or reproduction is not a concept confined to past centuries and decades, nor to locales outside the United States.
Growth of sole is sped up by selective breeding
Dutch doctoral researcher Robbert Blonk has found a way of speeding up the growth of North Sea sole considerably. This may make sole farming more viable.
Recombination hotspot stacks the DNA deck in finding a new diabetes susceptibility gene
The autoimmune disease type 1 diabetes (T1D), also known as juvenile diabetes, is diagnosed in approximately 70,000 children worldwide per year. Genetics is increasingly being recognized as playing a significant role in susceptibility ...
Genetically altered salmon? It doesn't stop there
(AP) -- We've always played with our food - even before we knew about genes or how to change them.
Capacity for exercise can be inherited, biologists find
Biologists at the University of California, Riverside have found that voluntary activity, such as daily exercise, is a highly heritable trait that can be passed down genetically to successive generations.
Core knowledge of tree fruit expands with apple genome sequencing
An international team of scientists from Italy, France, New Zealand, Belgium and the USA have published a draft sequence of the domestic apple genome in the current issue of Nature Genetics.
Fungi's genetic sabotage in wheat discovered
Using molecular techniques, Agricultural Research Service (ARS) and collaborating scientists have shown how the subversion of a single gene in wheat by two fungal foes triggers a kind of cellular suicide in the grain crop's ...
Nematodes vanquish billion dollar pest
The larvae of Diabrotica virgifera virgifera beetles wreak havoc on maize. Feasting on the plants' roots, they are estimated to cause $1 billion of damage every year in the US. Ted Turlings from the University of Neuchatel, Switze ...
Feeling Stressed? So is the Poplar -- But Hormone Suppression Could Help the Tree
(PhysOrg.com) -- People aren't the only living things that suffer from stress. Trees must deal with stress too. It can come from a lack of water or too much water, from scarcity of a needed nutrient, from ...
Dogs may provide an excellent model for understanding human complex diseases
In the new Swedish-Finnish study, published in Nature Genetics, the researchers identified five loci that predispose to an SLE-related disease in Nova Scotia duck tolling retrievers. The study indicates that the homogeneity of str ...
