Single gene mutation can sweep through bacterial population, opening the door for the concept of 'species'
Bacteria are the most populous organisms on the planet. They thrive in almost every known environment, adapting to different habitats by means of genetic variations that provide the capabilities essential ...
In new mass-production technique, robotic insects spring to life
(PhysOrg.com) -- A new technique inspired by elegant pop-up books and origami will soon allow clones of robotic insects to be mass-produced by the sheet.
Slower evolving bacteria win in the end
Virtual-twin plan could support surgery for soldiers
Amoebas farm bacteria and carry guards to protect their crops in the wild
Model organisms, brought into labs because they are easy to work with, adapt to the lab, often shedding characteristics that allowed them to survive in the wild. Scientists who work with model organisms rarely ...
Lost frog DNA revived
As part of a "Lazarus Project" to try to bring the Australian gastric-brooding frog back from extinction a UNSW-led team has succeeded in producing early stage cloned embryos containing the DNA of the frog, ...
Mammoth fragments from Siberia raise cloning hopes (Update)
Scientists have discovered well-preserved frozen woolly mammoth fragments deep in Siberia that may contain living cells, edging a tad closer to the "Jurassic Park" possibility of cloning a prehistoric animal, ...
Genetic discovery unlocks biosynthesis of medicinal compound in poppy
Scientists at the University of York and GlaxoSmithKline (GSK) Australia have discovered a complex gene cluster responsible for the synthesis of the medicinal compound noscapine.
How Salmonella forms evil twins to evade the body's defenses
An unusual regulatory mechanism that controls the swimmer/non-swimmer option in genetically identical Salmonella also impacts the bacteria's ability to cause infection.
Not 1, not 2, not 3, but 4 clones!
Xi-Jun Ren and Yang Xiang from Henan Universities in China, in collaboration with Heng Fan at the Institute of Physics of the Chinese Academy of Sciences, have produced a theory for a quantum cloning machine able to produce ...
Scientists first to characterize barley plant-stem rust spore 'communication'
Traditional thought has held that disease had to penetrate a plant to initiate resistance; however, two Washington State University scientists have established that a barley plant recognizes an invader and begins to marshal ...
Personalised stem cells back in the spotlight
Scientists on Wednesday said they had made strides in lab research in personalised stem cells, reviving interest in a goal clouded by fraud and ethical storms.
Few replicas as first cloned cat nears 10
Nearly 10 years after scientists cloned the first cat, predictions of a vast commercial market for the "resurrection" of beloved pets through cloning have fallen flat.
Why plant 'clones' aren't identical
A new study of plants that are reproduced by cloning has shown why cloned plants are not identical.
