An important cell in mice and humans' immune systems has been shown to have gut-healing properties in mice with a form of inflammatory bowel disease (IBD).

A doctor who witnessed the tribulations of mRNA vaccine pioneer Katalin Karikó warns that science is naturally hard, but the system that puts make-or-break financial pressures on American scientists makes it even harder.

It can begin with abdominal pressure from a bloating belly. This can escalate into cramping pain and nausea. Or, a sudden urge to flee to the toilet right now. 

Using a bacterial strain found in mangroves, researchers at Texas A&M University have uncovered a low-cost, sustainable method for producing bioplastics from sewage sludge and wastewater.

In bacterial battles, there is more than just direct killing. Some bacteria even challenge their prey by destroying their bacterial houses. We could learn a lot from these microscopic combats for our own fights against bacterial superbugs.

The human body is a league of nations for an unfathomable variety of microbes, kept in check by complex relationships with our immune system and carefully crafted truces with each other.

The astonishing secrets of fungal life raise profound questions

Magnetotactic bacteria have magnetosomes with which they can sense magnetic field lines. This allows magnetotactic bacteria to swim towards North or South

Penicillin, one of the greatest discoveries in the history of medicine, was a product of chance. After returning from summer vacation in September 1928, bacteriologist Alexander Fleming found a col…

We thought we had bigger things to worry about than Chinese bat coronaviruses. It is now clear we made a massive mistake.

A world premiere from Erasmus MC and Utrecht University: they found an antibody against COVID-19.

A new discovery could help lessen our reliance on fossil fuels by turning plant waste into biofuels, such as ethanol, in a much cheaper way than before. Among the many ways suggested to reduce humanity’s reliance on polluting fossil fuels is replacing them with biofuels. Now, researchers from Rutgers University have published a study to Green Chemistry showing they can produce these fuels from plant waste for a fraction of the cost of other methods.

In the battle against antibiotic resistance, many scientists have been trying to deploy naturally occurring viruses called bacteriophages that can infect and kill bacteria. Bacteriophages kill bacteria through different mechanisms than antibiotics, and they can target specific strains, making them an appealing option for potentially overcoming multidrug resistance. However, quickly finding and optimizing well-defined bacteriophages to use against a bacterial target is challenging.

In the afterglow of successful fecal transplants, researchers are now sniffing around vaginal fluids for the next possible bodily product to improve health—and they’re roused by the possibilities.

In 2017, a woman in Nevada died from a fairly common bacterial infection, Klebsiella pneumoniae. Her death wasn’t the product of medical oversight or inattention; rather, it came despite it. Her infection proved resistant to every antibiotic drug doctors threw against it, NPR reports. They ultimately exhausted 26 different drugs — the bacteria was resistant to every single one.

For the first time, scientists have used genetically modified viruses to treat a patient fighting an antibiotic-resistant infection. Isabelle Carnell-Holdaway, 17, began the experimental treatment after doctors lost all hope. She was struggling with a life-threatening infection after a lung transplant. With the new treatment, she has not been completely cured. But the Faversham, England, teenager has recovered so much that she has resumed a near-normal life.

A British teenager has made a remarkable recovery after being the first patient in the world to be given a genetically engineered virus to treat a drug-resistant infection. Isabelle Holdaway, 17, nearly died after a lung transplant left her with an intractable infection that could not be cleared with antibiotics. After a nine-month stay at Great Ormond Street hospital, she returned to her home in Kent for palliative care, but recovered after her consultant teamed up with a US laboratory to develop the experimental therapy.

When Graham Hatfull, PhD, a professor at the University of Pittsburgh specializing in phage biology and James Soothill, MD, a microbiologist at Great Ormond Street Hospital for Children (GOHS) in London, met over 20 years ago at a phage biology meeting in Tbilisi, Georgia, they could not have predicted that they would one day collaborate to save the life of a teenage girl with a Mycobacterium infection.
