Magnetic bacteria carry anti-cancer drugs to tumors

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.

Soil bacteria used to generate electricity

In a case of physics and biology coming together, researchers have successfully created conditions under which bacteria isolated from soil generate usable electricity.

Recoding E. coli to become resistant to all viruses

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.

Using grocery scanners to track foodborne outbreaks

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.

Breathing adversely affected by too much alcohol

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.)

Officials: Clean up efforts of Rio's Olympic waters have failed

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.

Can antibiotics be used to help combat Alzheimer’s disease?

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.

Exploring the properties of graphene with bacteria

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 about plastic waste in the oceans

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.

Farmers and microbiologists team up to tackle E. coli

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.

Essential Science: Taking on metabolic disorders with starch

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.

Beneficial bacteria protect against breast cancer

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.

FDA approves new cholera vaccine

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.

Bacterial ‘hairs’ used as electrical wires

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.

Nature Made recall over Salmonella, Staph fears in some products

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.

Portable tech identifies pathogens faster

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.

Will reducing antibiotic use lead to more infections?

London - A consensus is developing around restricting the use of antibiotics and antimicrobials. However, what is the impact on human health if the use of these pharmaceutical compounds is curtailed?

New study finds way of reducing the ‘sweet tooth’

Atlanta - Sugar carvings are one of the main reasons for the global rise in obesity. Researchers have been looking at new ways to reduce the craving for sugar and one potential means is through the use of bacterial cell fragments.

Biologically powered solar cells tested

The search for alternative forms of power, necessary to future-proof electricity generation in the face of dwindling sources of oil, has led to biological life forms. A new development is a so-called bio-solar cell.

Sugar content lowered in yogurt while keeping it sweet

Microbiologists in Denmark have altered the bacteria involved with yogurt production to create a "naturally" sweetened yogurt with a low sugar content.

Florida’s oranges continue to be hit hard by citrus greening

Miami - Cases of citrus greening continue to affect Florida’s orange groves. New figures indicate that up to 90 percent of the acreage and 80 percent of their trees are infected by the bacterial disease.

Essential Science: How natural products can help fight pathogens

Although synthetic medicines provide the basis for most modern antimicrobials, have all natural remedies been exhausted? A new research paper suggests there are still some herbs still to be exploited.

The 'tree of life' has no top and is still growing say scientists

Scientists can now say it truly is a small world once they have viewed the new tree of life unveiled last week. The new tree shows that almost two-thirds of the tree is made up of bacteria.

Essential Science: Gum infections can lead to a range of other diseases

Having a gum diseases can cause problems enough, leading to redness, soreness and discomfort. This, however, can be just the beginning. New research is connecting gum disease to a host of other infections.

Antibiotic resistance rates rise with children

London - In evidence of an emerging generational issue, half of children around the world could carry organisms resistant to the most commonly prescribed antibiotics and antimicrobials. This presents concerns for future treatments.

Essential Science: Why the microbiome of seminal fluid is important

New research discusses the microbiome of seminal fluid. Although focused on animals, the research could lead to a new area of medicine where the microorganisms in seminal fluid could be used to assess male health.

Training rats to sniff out TB sufferers

East African researchers are considering using the highly developed sense of smell of rats to screen for tuberculosis among prisoners in the crowded prisons in Tanzania and Mozambique.

Worth their weight in gold? Platinum forming bacteria

Australian researchers have found the important role played by specialist bacteria in the formation and movement of platinum. The organisms are also associated with the processing of other metals.
