Best of Last Week - Map of universe questioned, violent history of our faces and resistant bacteria found in food
Bacteria become 'genomic tape recorders'
MIT engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well suited for ap ...
Silicon alternatives key to future computers, consumer electronics
(Phys.org) —Researchers are reporting key milestones in developing new semiconductors to potentially replace silicon in future computer chips and for applications in flexible electronics.
Researchers predict electrical response of metals to extreme pressures
Research published today in the Proceedings of the National Academy of Sciences makes it possible to predict how subjecting metals to severe pressure can lower their electrical resistance, a finding that c ...
New class of industrial polymers discovered
(Phys.org) —Scientists from IBM Research have successfully discovered a new class of polymer materials that can potentially transform manufacturing and fabrication in the fields of transportation, aerospace, ...
'Lonely' bacteria increase risk of antibiotic resistance
Scientists from The University of Manchester have discovered that 'lonely' microbes are more likely to mutate, resulting in higher rates of antibiotic resistance.
A possible alternative to antibiotics
Scientists from the University of Bern have developed a novel substance for the treatment of severe bacterial infections without antibiotics, which would prevent the development of antibiotic resistance.
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 ...
Using test tube experiments to study how bacterial species evolve antibiotic resistance
Given a critical change in the environment, how exactly, do species adapt? Professor Tom Vogwill and colleagues wanted to get at the heart of this evolutionary question by measuring the growth rates and DNA mutations of 8 ...
Study shows manure from cows not given antibiotics still causes increase in resistant bacteria in soil
'Programmable' antibiotic harnesses an enzyme to attack drug-resistant microbes
The multitude of microbes scientists have found populating the human body have good, bad and mostly mysterious implications for our health. But when something goes wrong, we defend ourselves with the undiscriminating ...
Attacking persister cells that are responsible for making bacteria resistant to new drugs
(Phys.org) —We face an urgent global health problem because scientists are not developing new antibiotics as fast as bacteria are developing antibiotic resistance.
Battling superbugs with gene-editing system
In recent years, new strains of bacteria have emerged that resist even the most powerful antibiotics. Each year, these superbugs, including drug-resistant forms of tuberculosis and staphylococcus, infect ...
Chemists modify antibiotic to vanquish resistant bacteria
Scientists at The Scripps Research Institute (TSRI) have devised a new antibiotic based on vancomycin that is powerfully effective against vancomycin-resistant strains of MRSA and other disease-causing bacteria.
