A new research project has shown promise in using magnetic bacteria as a vehicle for delivering anti-cancer drugs more accurately to tumors in patients.

It’s an old wives tale – “feed a cold and starve a fever.” But does it come with any scientific basis? One research laboratory has put the aphorism to the test.
|
|
A new report has detected a species of Bacillus, genetically distinct to the bacterium that causes anthrax, which causes a similar disease in chimpanzees, gorillas and other animals in Africa.
|
|
Dig deep and there are potentially hundreds of bacteria on Earth that have yet to be discovered or characterized. One recent discovery relates to fracking where a new genus of bacteria has been discovered.

London -
In 1665 London was ravaged by a deadly plague that was only stopped by an equally great fire. New evidence, from examining bones of the victims, has pinpointed the causative organism.
|
|
Are bacteria in the human blood system responsible for indirectly triggering a range of diseases? New research suggests a link to strokes and heart attacks, and other ill-health conditions.
|
|
Agricultural scientists have isolated a receptor used by tomatoes to detect the infectious agent that causes bacterial speck disease. The receptor could be transferred into other crops to make them disease-resistant.
|
|
A common type of bacteria, carried by many women, has been linked with premature delivery and stillbirths. This understanding may help to reduce the number of deaths.
|
|
Introducing genetically modified bacteria into the intestines of mice appears to protect the rodents from obesity. This could become a treatment option for people.
|
|
Washington -
Over the past ten years the Jefferson Memorial has turned from a white-ish sandstone color to a dark-grey. This has happened due to a microbial biofilm.
|
|
A global study of Salmonella enteritidis bacteria (which causes blood poisoning) has found three separate types of bacteria. This indicates that control of infection risks could become more complicated.
|
|
Some bacteria have the ability to ‘swim’ in a controlled fashion through the use of appendages called flagella. Researchers think that disabling these flagella is a key step towards infection control.
|
|
Toronto -
Studies have taken place in Canada whereby magnetic bacteria are used to power nano-devices, to help ferry anti-cancer medicines to sites of tumors. Such devices offer faster and more precise drug delivery.
|
|
In a case of physics and biology coming together, researchers have successfully created conditions under which bacteria isolated from soil generate usable electricity.
|
|
Harvard -
Scientists are close to finishing recoding the Escherichia coli bacterium to work with a different genetic code — one that differs to all other genetic codes on Earth, the organism will have some interesting properties.
|
|
As an example of using large volumes of data for the public good, researchers have shown data collected from supermarket and grocery store scanners helps with tackling foodborne illness outbreaks and preventing food contamination.
|
|
A new alcohol health alert: researchers have found that people who drink excessively have lower levels of nitric oxide in their exhaled breath, compared with the rest of the population. This lowers the defenses against harmful bacteria.
|
|
Warwick -
There are many cases of zoonotic infections, where pathogens are transferred from an animal to a person (Ebola virus is an example.) However, no cases, until now, have been reported the other way around (human to animal.)
|
|
Rio De Janeiro -
Athletes taking part in the marathon swimming, sailing and windsurfing events next month at the Rio Summer Olympic Games have been warned by health officials to keep their mouths closed when in the water.
|
|
Chicago -
In a potentially significant breakthrough, a long dose of antibiotics has reduced Alzheimer’s-related plaques in studies using mice.
|
|
How can biological science help the electronics sector? The answer is bacteria helping to produce a new generation of nanoelectronic materials.
|
|
Nanoscale ripples can be introduced onto the surface of graphene through the use of microscopic organisms. Scientists have used rod-shaped bacteria to alter the conduction of electricity on sheets of graphene.
|
|
New concerns have been raised about the impact of plastic waste dumped into the world’s oceans. A new report indicates that waste from Northern Europe, for example, will reach the Arctic within two years.
|
|
Michigan -
The bacterium Escherichia coli provides a risk to consumers through food poisoning. One point of origin is the farm, through farming practices. Microbiologists and farmers have teamed up to reduce opportunities for transmission.
|
|
A new study indicates that supplementing the diet of people with metabolic syndrome with resistant starch helps improve the condition. This happens by altering gut bacteria.
|
|
New research suggests that women who avoid breast cancer have a different microbial profile (microbiome) to those who are at a greater risk of contracting the disease.
|
|
The U.S. Food and Drug Administration (FDA) has approved a new vaccine for cholera. The drug is branded Vaxchora and itt targets a specific cholera called serogroup O1.
|
|
Researchers have discovered that the molecular electronic arrangement with hair-like filaments on a species of bacteria provides them with an electrical conductivity comparable with copper.
|
|
Pharmavite LLC, the parent company of Nature Made, has announced a voluntary Class 1 recall of some specific dietary supplements over fears they may be contaminated with bacteria, yeast and molds, according to a number of websites.
|
|
In the medical field, the rapid identification of bacterial pathogens in response to a disease is crucial. An hour or two either can be the difference between life and death. New technological advances are helping to speed up this process.

This key experiment shows the successful protection of a phage-sensitive bacterial strain against a virus. Top-right - bacteria growing in the absence of a virus; Top-left - holes in the culture caused by an infecting virus; Bottom - when equipped with specific CRISPR defense system components, the bacteria became resistant to the virus.
