New Therapy Targets Gut Bacteria To Suppress Food Allergies

A new study identified the species of bacteria in the human infant gut that protect against food allergies. A resulting oral therapy in mice has replenished the “good” bacteria, prevented food allergies from forming and even suppressed some pre-existing diseases. Contrary to the current therapies, it has the potential to treat food allergies at a much broader scope.

Scientists Are Gene-Hacking Bacteria To Mass-Produce Spider Silk

Scientists from Washington University in St. Louis have found a new method to genetically alter bacteria and acquire super-strong spider silk. Farming spiders is incredibly inefficient and finding a way to mass-produce the material would bring us a step away from a ready supply of incredibly resilient fabrics. The method could clear the way for the production of other scarce proteins that could even be used for future space missions.

Kimchi-Derived Probiotics: A Remedy for Eczema?

Most people who have been to Korean restaurants will be familiar with a signature Korean dish called Kimchi. This traditional dish has been consumed for thousands of years and is made from a mixture of Chinese cabbage, herbs and spices which is then fermented by naturally occurring lactic acid bacteria. Apart from giving kimchi its distinctive taste, it turns out that these probiotic bacteria might also be good for our health.

Genetically Engineered Viruses Seek and Destroy E. coli in Drinking Water

Food scientists from Cornell University have developed a test for rapid detection of E. coli in drinking water using genetically-engineered bacteriophages. It can be administered locally in hard-to-reach areas around the world and provides results within hours. Obtaining quick and accurate results is a current bottleneck in preventing infection and could save many.

Bacteria “Harpoon” DNA To Speed Up Their Evolution

Researchers from Indiana University (IU) have made the first direct visual observation of bacteria taking up foreign DNA from its surrounding. It is a key step in their process of rapidly evolving new traits, including troublesome drug resistance. The new methods developed by the researchers provided them with the ability to catch this mechanism on film.

Sugar Additives Might be Feeding Aggressive Superbugs

New research suggests that some of the additives that extend the shelf life and improve the texture of processed foods may have harsh side effects on the human gut microbiome. The rise in deadly cases of a terrible gut infection caused by Clostridium difficile is the outcome of adding the sugar trehalose to almost all of our processed food.
