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.

Tiny reason for why foodborne illness occurs with vegetables

Researchers find tiny ridges on vegetables that enable harmful viruses to adhere to commonly eaten food. Some fruits and vegetables are less likely to become contaminated than others.

Essential Science: Semi-synthetic bacterium created

Scientists have created a semi-synthetic, functioning bacterium in the lab that has fewer than 500 genes. The importance of "500" is that no bacterium in nature has less than 500 genes.

Bacteria communicate with each other in newly found ways

Researchers have discovered previously unknown ways by which bacteria ‘communicate’ with each other. These sensory mechanisms are important in terms of how diseases might spread.

Essential Science: Pathogenic organisms may trigger Alzheimer's

A possible connection between viral and bacterial pathogens and the neurodegenerative disorder Alzheimer's disease has been made by a research group. While not definitive, the research opens up a new area to investigate.

Dealing with cavities by taking a pill

A new study suggests that a newly found bacterium could help address cavity formation, by keeping harmful bacteria at bay. The bacterium could be processed and be made available in pill form, as a type of oral probiotic.

Pathogen fighting cloth shows success

An anti-bacterial cloth, effective against a range of pathogenic bacteria, has been developed. In studies the cloth has proven to be effective in avoiding wound contamination. Applications include bandages and face masks.

Fighting infections with viruses, as antibiotics fail

Paris - When doctors told Christophe Novou that his leg would have to be amputated at the hip due to a raging bacterial infection, the 47-year-old Frenchman thought about killing himself.

New insight into bacterial pathogens in the body

Researchers have gained a new insight as to how some pathogenic bacteria are carried around the human body quickly. This is by attaching themselves to the body’s immune cells.

New, faster test for Lyme disease developed

A new method for the early detection of Lyme disease has been developed. Current tests for Lyme bacteria, close to the point of probable infection, are normally produce "false" negative results. The new method overcomes this problem.

Lithium battery component poses environmental risk

A component from lithium batteries — used to power laptops and smartphones — has been found to affect the ecosystem by inhibiting a beneficial bacterium that process toxins.

Inside the connection between bacterial toxins and obesity

Scientists have made a connection between bacteria that reside in the human gut (specifically toxic by-products) and obesity. The research adds to the body of work about the microbiome.

Curing citrus greening with lasers

Tampa - A new method for tackling the serious citrus greening disease has been proposed. This involves powering a laser beam towards citrus leaves. Initial trials have proved successful.

Rats pose serious health threat to people and poultry

Vancouver - Rats pose serious health threats to communities and farms, according to a new study. This is because rats readily pick up diseases from one environment and spread them to another. Most at risk are humans and poultry.

Do our bodies really have more microbes than human cells?

Pick up a text book on microbiology or human physiology. Chances are you’ll stumble across a reference to the number of microorganisms in the human body exceeding the number of cells ten-fold. But is this correct?

Helping California's grape and wine industries with vine disease

San Fransisco - Researchers have pinpointed how Pierce's disease is transmitted from insects to grapevines. The disease costs California's grape and wine industries in excess of $100 million each year.

Exercising early changes gut microbes for the better

A new study has found how exercising while younger alters the types of gut microbes so that the composition is different than a person who takes up exercise later in life. These changes to the gut microbiome are beneficial.

Treating heart disease through the gut

Scientists have shown that focusing on microorganisms within the human gut could be the answer to prevent a type of heart disease associated with diet.

Men and women deposit different types of bacteria

The types of bacteria found in the home vary according to whether more men or women live in the house, as well as whether household pets are present.

Do antibiotics to treat MRSA make patients sicker?

New evidence suggests certain antibiotics intended to treat patients with MRSA infections are actually causing more harm than good.
