Totally rad: Scientists create rewritable digital data storage in DNA
(Phys.org) -- Scientists from Stanford's Department of Bioengineering have devised a method for repeatedly encoding, storing and erasing digital data within the DNA of living cells.
Genomics analysis demonstrates natural selection at work
(Phys.org)—A team of researchers at Michigan State University has documented the step-by-step process in which organisms evolve new functions.
X-rays reveal how soil bacteria carry out surprising chemistry
Researchers working at the SLAC National Accelerator Laboratory have used powerful X-rays to help decipher how certain natural antibiotics defy a longstanding set of chemical rules a mechanism that ...
How zinc starves lethal bacteria to stop infection
(Phys.org) —Australian researchers have found that zinc can 'starve' one of the world's most deadly bacteria by preventing its uptake of an essential metal.
Designer viruses could be the new antibiotics
Bacterial infections remain a major threat to human and animal health. Worse still, the catalogue of useful antibiotics is shrinking as pathogens build up resistance to these drugs. There are few promising ...
Time in a bottle: Scientists watch evolution unfold
A 21-year Michigan State University experiment that distills the essence of evolution in laboratory flasks not only demonstrates natural selection at work, but could lead to biotechnology and medical research ...
New method for mass-producing high-quality DNA molecules
A new method of manufacturing short, single-stranded DNA molecules can solve many of the problems associated with current production methods. The new method, which is described in the scientific periodical ...
Researchers 'fish new pond' for antibiotics
Researchers at McMaster University are addressing the crisis in drug resistance with a novel approach to find new antibiotics.
Oxygen, phosphorous and early life on Earth
Two billion years ago the Earth system was recovering from perhaps the single-most profound modification of its surface environments: the oxygenation of the atmosphere and oceans. This led to a series of major changes in ...
Ancient teeth bacteria record disease evolution
DNA preserved in calcified bacteria on the teeth of ancient human skeletons has shed light on the health consequences of the evolving diet and behaviour from the Stone Age to the modern day.
Germ-killing nanosurface opens up new front in hygiene (Update)
Imagine a hospital room, door handle or kitchen countertop that is free from bacteria—and not one drop of disinfectant or boiling water or dose of microwaves has been needed to zap the germs.
Handheld plasma flashlight rids skin of notorious pathogens
(PhysOrg.com) -- A group of Chinese and Australian scientists have developed a handheld, battery-powered plasma-producing device that can rid skin of bacteria in an instant.
Like humans, amoebae pack a lunch before they travel
(PhysOrg.com) -- Some amoebae do what many people do. Before they travel, they pack a lunch. In results of a study reported today in the journal Nature, evolutionary biologists Joan Strassmann and David Quelle ...
Bacteria that assist fungus-farming ants may be a source of new drugs
In the Atlantic Forest of Brazil, leaf-cutter ants carry fresh foliage back to their home colony. There, the partially digested leaves nourish a "garden" of white fungus that the ants cultivate to feed their ...
