In order to combat the growing problem of antibiotic resistance, a group of scientists from MIT are using artificial intelligence to discover new and effective antibiotics. They were able to predict a powerful new antibiotic compound that is effective against many dangerous pathogens. Continue reading Artificial Intelligence – our new MVP against infections?
CIFAR Fellows’s paper questions whether diabetes, heart attacks and strokes are actually non-communicable diseases (NCDs). Microbiota (bacteria, viruses, fungi) that spread flu, HIV/AIDS, may also carry NCDs. People with NCDs have damaged microbiota, causing disease when transmitted into healthy animals. Spouses and cohabitants’ shared lifestyles and environments also lead to gut bacteria transfer.

CRISPR is a highly effective immune system that defends bacteria from viruses. It was recently shown that some viruses have evolved counter-defenses that protect their DNA with a nucleus-like structure. Continue reading Some viruses can defeat CRISPR with nucleus-like compartments
Mucus is not just the awful phlegm from your cough, it actually has the ability to tame bacteria infection! Scientists at MIT recently discovered that the glycans on our mucus can actually trigger biochemical responses that protect us from pathogens. Read Wei Li’s article to learn more. Continue reading The Key to Taming Bacteria: Mucus Sugars
Recently, scientists revealed that bacteria were able to produce a climate cooling gas, which could be useful in mitigating climate change Continue reading New AC for the summer? Bacteria produces climate-cooling gas
A group of scientists uncovered a commensal gut bacteria, Akkermansia muciniphila, that can significantly ameliorate ALS symptoms in mice, and also prolong their lifespan. Their results highlight the potential of modulating the gut microbiome to treat ALS. Continue reading The Next Ice Bucket Challenge: Modulating Your Gut Microbiome to Treat ALS
Influenza A is the virus responsible for the Spanish Flu pandemic, which wiped out 3-5% of the human population in the early 20th century. The annual influenza outbreak occurs in the autumn and winter, although it is not normally deadly for healthy adults. There is currently no vaccine providing permanent protection against influenza A because the virus mutates and changes so often, requiring a yearly … Continue reading The Actual Master of Disguise: The Flu
Our skin is a protective barrier to bacterial infection, but damage to the skin allows bacteria to enter. Normally, our immune system kills the bacteria and allows wounds to heal. However, certain diseases can overload the immune system and lead to heavy infection. Antibiotics are commonly used to treat heavy bacterial infection, but bacteria can develop drug resistance after too much exposure. A team at … Continue reading The Quest for Better Bandages Turns to Nanofibers
In order to adapt to their environments, it is important that bacteria be able to mix up their genetic code. One way that bacteria do this is by taking up bits of free-floating foreign DNA that can be released by other kinds of bacteria into their environments when they die. This process is called ‘transformation.’ The pieces of DNA can occasionally encode components that make … Continue reading Bacteria snatch up foreign material using specialized arm-like structures
The colonies in this image display some of the diversity of pigment production in Pseudomonas aeruginosa. The blue-green colonies contain a pigment called pyocyanin, which is known to be toxic to human cells and helps the bacteria establish a niche during infections. The colonies containing a brown halo produce the brown pigment pyomelanin, which is thought to help the bacteria scavenge for iron, an essential … Continue reading Colonies 5
