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.

Proposal for the assessment of new methods in plant breeding

CRISPR/Cas9 is a new method for targeted genetic changes. Together with other methods, it is part of the so-called genome editing toolbox. At the moment, genome-editing is mostly discussed in the context of medical applications, ...

Grafting with epigenetically-modified rootstock yields surprise

Novel grafted plants—consisting of rootstock epigenetically modified to "believe" it has been under stress—joined to an unmodified scion, or above-ground shoot, give rise to progeny that are more vigorous, productive ...

Science to help rice growers affected by Japan's tsunami

Under a year since a huge tsunami inundated paddy fields in Japan with salty sludge, scientists are near to developing locally-adapted, salt-tolerant rice. Following a Japan-UK research collaboration, a new method for marker ...

Research identifies wild ancestor genes for crop improvement

Using the genetic variation found in wild and exotic rice species, researchers are providing breeders with genomics tools and knowledge to develop higher yielding, stress-tolerant varieties, a Cornell researcher reported ...
