Best of Last Week – speed of light may be wrong, fungus fights resistant bacteria and link between pesticides and autism
Study shows use of feces as building material by termites serves as antibiotic
Breakthrough allows fast, reliable pathogen identification
Life-threatening bacterial infections cause tens of thousands of deaths every year in North America. Increasingly, many infections are resistant to first-line antibiotics. Unfortunately, current methods of culturing bacteria ...
Bacterial spare parts filter antibiotic residue from groundwater
Researchers at University of Cincinnati have developed and tested a solar-powered nano filter that is able to remove harmful carcinogens and antibiotics from water sources – lakes and rivers – at a significantly higher ...
Attacking MRSA with metals from antibacterial clays
In the race to protect society from infectious microbes, the bugs are outrunning us. The need for new therapeutic agents is acute, given the emergence of novel pathogens as well as old foes bearing heightened antibiotic resistance.
Team uses solar-powered proteins to filter harmful antibiotics from water
(Phys.org) —New research, just published, details how University of Cincinnati researchers have developed and tested a solar-powered nano filter that is able to remove harmful carcinogens and antibiotics ...
Beneficial tea tree oil given all-clear
After two recent reports suggesting that exposing bacteria to tea tree oil may contribute to antibiotic resistance in humans, an international study - led by researchers at The University of Western Australia ...
Scientists unveil secrets of important natural antibiotic dermcidin
An international team of scientists has discovered how an important natural antibiotic called dermcidin, produced by our skin when we sweat, is a highly efficient tool to fight tuberculosis germs and other dangerous bugs.
New tool for mining bacterial genome for novel drugs
Vanderbilt biochemists have discovered that the process bacteria undergo when they become drug resistant can act as a powerful tool for drug discovery.
Antimicrobial resistance in fish pathogenic bacteria and other bacteria in aquatic environments
Little attention has been paid to the use of antibiotics in the aquaculture industry as one reason for the increase in bacteria resistant to antibiotics and the spread of such resistance to other bacteria.
Study reveals complex process behind sea sponge's toxicity
(Phys.org)—The solution to a biochemical puzzle over the molecular make-up of a coral reef sea sponge (Theonella swinhoei) has revealed the origin of its extremely toxic agents.
New research identifies prime source of ocean methane
Up to 4 percent of the methane on Earth comes from the ocean's oxygen-rich waters, but scientists have been unable to identify the source of this potent greenhouse gas. Now researchers report that they have ...
Garlic constituent blocks biofilm formation, could benefit CF patients and others
E Pluribus Unum, the motto of the United States, could just as well apply to biofilm-forming bacteria. Bacterial biofilms are far more resistant than individual bacteria to the armories of antibiotics we have devised to combat ...
Genes culled from desert soils suggest potential medical resource
Despite their ecologic similarity, soils from three geographically distinct areas of the American southwest harbor vastly different collections of small, biosynthetic genes, a finding that suggests the existence of a far ...
