Study shows how diet can prevent a mid-life microbiome crisis and improve brain health

An animal study revealed prebiotic dietary interventions in middle-aged mice reduced signs of brain inflammation and ...

A fascinating new study is suggesting that a shift in gut bacteria in our middle-age could trigger a process that plays a role in cognitive decline in our later years. And diet may be the key to encouraging the growth of beneficial bacteria that benefit healthy brain aging.

Wound dressing uses electricity to bust up antibiotic-resistant bacterial infections

Scientists have developed a wound dressing that can generate a weak electrical field to break down ...

An incredible new study has demonstrated the potential of a wound dressing that can fight bacterial infections using a weak electrical field. Offering a novel way to battle antibiotic resistant infections, the dressing has been approved by the FDA and is currently being tested in human burn patients.

Alarming study finds plastic ocean pollution harms bacteria that produces the oxygen we breathe

Chemicals that leach out of plastic rubbish were found to impair the growth of bacteria in ...

An important new study is raising novel concerns over the effects of plastic pollution in our oceans. For the first time researchers investigated how a common ocean bacteria, responsible for producing over 10 percent of oxygen in the atmosphere, is negatively impaired by chemicals that can leach out of plastic products.

Gene-modified viruses rescue patient from drug-resistant ‘superbug’

Doctors normally resort to bacteriophages (bacteria-killing viruses) to kill antibiotic-resistant "superbugs" only when they've run out of options, in part because it's difficult to find the ideal example. It can take months or more just to find a v...

Directed evolution gets bacteria designing new antibiotics for us

Caltech researchers are using directed evolution to make bacteria create new antibiotics

Evolution is an incredible process, allowing life to adapt to changes in its environment. In the 1990s, the lab of Frances Arnold showed how we can turn this process to our advantage by manipulating microbes into evolving in a certain way, which could lead to new drugs and other breakthroughs. The discovery earned Arnold the 2018 Nobel Prize in Chemistry, and now her team is using the technique to develop new antibiotics.

World-first human treatment of antibiotic-resistant infection with genetically modified virus

Three bacteriophages, or bacteria-eating viruses, were administered to the young patient suffering from a major antibiotic-resistant ...

A new case study, described in the journal Nature Communications, outlines the world's first use of a genetically modified virus to treat a life-threatening antibiotic-resistant bacterial infection. The successful treatment paves the way for larger clinical trials to try to establish how broadly effective this experimental process could be in wider patient populations.

Newly discovered "jumping" superbug gene threatens last-resort antibiotic

Graphic depicting the newly discovered mcr-9 gene

Health experts harbor well-grounded fears over the rise of antibiotic-resistant bacteria, and the continuing streak of newly discovered threats will do little to allay the concerns. The latest comes from scientists at Cornell University, who have discovered a previously unknown gene that can leap between organisms to facilitate resistance to an important last-resort antibiotic.

New compound reverses drug resistance in tuberculosis

A new compound could knock out tuberculosis bacteria's resistance to antibiotics

Tuberculosis (TB) remains one of the most lethal infections in the world, resulting in over 1.5 million deaths each year. While it is currently curable, the bacteria responsible for it are fast evolving resistance to our antibiotics, thwarting attempts to keep the disease under control. Now, scientists have found a new compound that can boost the power of existing antibiotics and even reverse the bugs' resistance.
