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.
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.
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 ...
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 ...
Genetic differences that make some people susceptible to meningitis revealed in major new study
Genetic differences that make some people susceptible to developing meningococcal meningitis and septicaemia, and others naturally immune, are revealed in a new study of over 6,000 people, published today in Nature Genetics.
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 ...
Single gene lets bacteria jump from host to host
First detailed microscopy evidence of bacteria at the lower size limit of life
Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get. The research was led by scientists from the U.S. Department of ...
Research efforts yielding major advances in understanding immunological memory
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 ...
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 ...
Innovative technique may transform the hunt for new antibiotics and cancer therapies
Antibiotic resistance is depleting our arsenal against deadly diseases and infections, such as tuberculosis and Staph infections, but recent research shows promise to speed up the drug discovery process.
Marine bacteria are natural source of chemical fire retardants
Researchers at the University of California, San Diego School of Medicine have discovered a widely distributed group of marine bacteria that produce compounds nearly identical to toxic man-made fire retardants.
Galectins direct immunity against bacteria that employ camouflage
Our bodies produce a family of proteins that recognize and kill bacteria whose carbohydrate coatings resemble those of our own cells too closely, scientists have discovered.
