Mathematical description of relationship between thickness, temperature, and resistivity could spur advances
MIT researchers have discovered a new mathematical relationship—between material thickness, temperature, and electrical resistance—that appears to hold in all superconductors. They describe their findings ...
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 ...
Probing bacterial resistance to a class of natural antibiotics
Antimicrobial peptides are a distinctive class of potent, broad-spectrum antibiotics produced by the body's innate immune system—the first line of defense against disease-causing microbes.
Human DNA shows traces of 40 million-year battle for survival between primate and pathogen
Examination of DNA from 21 primate species - from squirrel monkeys to humans - exposes an evolutionary war against infectious bacteria over iron that circulates in the host's bloodstream. Supported by experimental ...
New research could revolutionize genomic sequencing of drug-resistant bacteria
New nanopore DNA sequencing technology on a device the size of a USB stick could be used to diagnose infection - according to new research from the University of East Anglia and Public Health England.
Learning anti-microbial physics from cicada
(Phys.org) —Inspired by the wing structure of a small fly, an NPL-led research team developed nano-patterned surfaces that resist bacterial adhesion while supporting the growth of human cells.
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 ...
