3D printing for detecting off-milk in cartons

Researchers have used 3D printing to develop a sensor that can be placed inside a carton of milk to detect if the milk is fit for drinking and to alert if the milk has "gone off."

Probiotics are more effective in conjunction with dairy

Probiotics are more effective when used in conjunction with dairy products compared with other foodstuffs or beverages, according to a new study. The study does have some limitations.

Seeking a cure for nasty flesh-eating disease

Scientists are a step closer to dealing with Buruli ulcer, a horrible "flesh-eating" disease. The disease is bacterial and it causes blood clots on the skin.

Pneumonia is a growing cause of hospitalization in U.S.

Washington - Pneumonia is one of the leading causes of hospitalization among adults in the U.S., to the extent that the medical costs exceeded $10 billion. It is also a major reason for death.

New treatment for acne is effective

Washington - The slow release of nitric oxide, through nanotechnology, can be an effective cure against acne, according to new research. The nitric oxide tackles the bacteria that cause the spots and pimples on the skin to flare up.

Gut bacteria provide coffee berry borers with super-resistance

New York - Scientists have worked out why coffee berry borers manage to cause so much damage to coffee plants around the world, despite being exposed to high levels of caffeine that would ordinarily be toxic. The answer is bacteria.

Garlic helps treat urinary tract infections

Extracts of garlic could help to combat types of multi-drug resistant bacterial pathogens that can cause urinary tract infections (UTI), according to new research.

Warning as hot weather causes Salmonella infections to rise

Baltimore - Almost everyone is enjoying the hot weather that the summer brings, but not, perhaps, the odd rain shower. When enjoying food, especially outside, care must be taken with avoiding food poisoning. New research suggests a new summertime risk.

Can bacteria reduce aggressive instincts?

A new study suggests that certain bacteria can alter the tendency for an animals to display aggressive behavior. This relates to studies conducted on scientists' favorite lab model: fruit flies.

Tiny genetic shift led to 'The Black Death' and worse

The bacterium responsible for plague — Yersinia pestis — gained its pathogenic activity through one tiny genetic alteration, according to new research. This alteration led to the bubonic plague.

Cracking down on recreation water infection

Bethesda - The weather’s getting hotter and many people like to play and swim in public pools. Sometimes these communal areas can be sites of contamination and infection. The CDC has offered new advice.

Biological lock-and-key for GMO safety

Researchers have developed a way to allay one concern with GMOs entering the environment. This is based on a molecular lock-and-key, to inactivate unwanted microbes.

Tsetse fly, sleeping sickness and the bacterial mystery

Scientists are edging closer to wiping out sleeping sickness worldwide. However, to do so a greater understating of the relationship between the Tsetse fly and the disease causing parasite is required.

Infection rates running high in Spanish hospitals

Madrid - People at, or having recently left, hospitals in Spain have a 6 to 8 percent chance of contracting an infection, according to a new report. The issue is a further example of the rise in antimicrobial resistant bacteria.

Bacteria linked to type 2 diabetes

A new research study suggests that bacteria may have a role in whether a person develops type 2 diabetes. At this stage, the finding is based on an animal model.

New software tracks fecal contamination

Madrid - New software allows medics to track fecal contamination throughout all types of water, from seas to rivers. The software makes use of biological changes to water and then uses this to make predictions of the direction that contamination may spread.

Treatment of wastewater raises new health concern

A new concern has been expressed about the presence of large numbers of antibiotics in wastewater. Here treatments to "clean up" wastewater may be modifying the antibiotics and, by doing so, triggering a rise in antibiotic resistant bacteria.

Eyes differ, risk to contact lens wearers revealed

New York - Researchers, through analysing thousands of eye specimens, have concluded that the risk of infection to contact lens wearers depends on the individual and that the risk can change over time. This is due to the microbes in the eye.

Close to the bone: Avoiding infections with nanotech

Sheffield - Researchers have harnessed nanotechnology in order to avoid deep bone infections, where infections stem from bacteria and fungi. These types of infections can occur following dentistry.

U.S. anthrax error originated from military base

Bethesda - The U.S. military mistakenly shipped live anthrax samples across the country to a commercial lab in Maryland. The source of the error has been traced to a military location in the Utah desert.

Campylobacter rates increase for chickens sold in the U.K.

New figures, produced by the U.K. Food Standards Agency, show a marked increase in the detection of food-poisoning bacteria in chickens sold in British supermarkets.

Is mathematics the answer to antibiotic resistance?

Finding new drugs to combat antibiotic resistance is a complex task and running different biological scenarios can take years. To help screen potential drug candidates, researchers have developed a mathematical model.

Fecal transplant donor population 'stalls'

The rise of fecal transplants, as therapy to treat conditions like recurring bacterial infections caused by Clostridium difficile, have slowed down due to fewer people being suitable donors than medics had predicted.

Luminescent bacteria help diagnose cancer

Scientists have come up with a novel way to detect liver cancer. The approach makes use of beneficial bacteria. Through genetic engineering, these bacteria emit a luminescent pulse when cancer is present.

Half of chickens sold contain problem viruses

Vienna - Scientists have discovered that over 50 percent of chickens sold in Austria as meat products contain viruses that can transfer antibiotic resistant genes between bacteria.

Taking on bacterial resistance with 'resistance breakers'

As part of the fight against antibiotic resistant bacteria, scientists are looking at a new research stream based on so-termed "resistance breakers."

Vancouver student scoops top prize at Intel science fair

Vancouver - Canadian student Raymond Wang has won $75,000 at an international science and engineering fair. This is for designing a way to better protect airline passengers from pathogens.

Call for fund to develop new antibiotics

A British economist is calling on the world's leading pharmaceutical companies to set up a $2 billion fund to enable research into new antibiotics.

New campaign to end antibiotic use in farm animals

Social campaign group Avaaz is seeking to reduce the amount of antibiotics administered to farm animals. The group points out that the use of these drugs has fallen in Europe, with the exception of some territories like the U.K.

Using bacteria to deliver drugs

Boston - By re-engineering protein-shuttling machinery, researchers have used bacteria to inject a particular protein into mammalian cells.

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.
