Powerful gene-editing tool appears to cause off-target mutations in human cells
In the past year a group of synthetic proteins called CRISPR-Cas RNA-guided nucleases (RGNs) have generated great excitement in the scientific community as gene-editing tools. Exploiting a method that some bacteria use to ...
Scientists study how complexity developed from simple cell
(Phys.org) —Consider this a matter of scrambling down the family tree to its roots. Really old roots. Or perhaps it's more like blowing the dust off the family album—the human album—and opening to the first pages billions ...
Bacteria swim with whole body, not just propellers
When it comes to swimming, the bodies of some bacteria are more than just dead weight, according to new research from Brown University.
Fighting bacteria—with viruses
Research published today in PLOS Pathogens reveals how viruses called bacteriophages destroy the bacterium Clostridium difficile (C. diff), which is becoming a serious problem in hospitals and healthcare institutes, due to its re ...
Study finds specialized bacterial cells found in the gut produce steroid hormones
The human gut is home to trillions of bacteria, many of which play an important role in helping the body strike a healthy balance. In the gut, bacteria are involved in the synthesis of vitamins, as well as ...
New clues to how bacteria evade antibiotics
Scientists have made an important advance in understanding how a subset of bacterial cells escape being killed by many antibiotics.
Biophysicists unravel secrets of genetic switch
When an invading bacterium or virus starts rummaging through the contents of a cell nucleus, using proteins like tiny hands to rearrange the host's DNA strands, it can alter the host's biological course. The invading proteins ...
Could viruses be used to treat acne?
Watch out, acne. Doctors soon may have a new weapon against zits: a harmless virus living on our skin that naturally seeks out and kills the bacteria that cause pimples.
Living power cables discovered
A multinational research team has discovered filamentous bacteria that function as living power cables in order to transmit electrons thousands of cell lengths away.
Researchers divide enzyme to conquer genetic puzzle
Rice University researchers have found a way to divide and modify enzymes to create what amounts to a genetic logic gate.
Biological activity alters the ability of sea spray to seed clouds
Ocean biology alters the chemical composition of sea spray in ways that influence their ability to form clouds over the ocean. That's the conclusion of a team of scientists using a new approach to study tiny atmospheric particles ...
Biologists develop new method for discovering antibiotics
Biologists at the University of California, San Diego have developed a revolutionary new method for identifying and characterizing antibiotics, an advance that could lead to the discovery of new antibiotics to treat antibiotic ...
Bacterial colonies evolve amazing diversity
Like human societies—think New York City—bacterial colonies have immense diversity among their inhabitants, often generated in the absence of specific selection pressures, according to a paper published ahead of print ...
Some Earth bacteria survive and grow at extremely low pressure, may aid Mars research
(Phys.org)—University of Florida researchers have discovered for the first time that some Earth bacteria can live under the same low pressure conditions found on Mars.
