Having healthy gut flora -- the trillions of bacteria housed in our intestines -- could lower the risk of infection following knee and hip replacement surgeries, while an unhealthy intestinal flora may increase the risk of infection.

Researchers have developed an automated, robotic training device that allows mice to learn at their leisure. The technology stands to further neuroscience research by allowing researchers to train animals under more natural conditions and identify mechanisms of circuit rewiring that occur during learning.

Researchers embarked on a study to investigate whether early changes in energy-related metabolites in the blood -- measured shortly after chemotherapy -- could be used to identify patients who developed heart toxicity at a later time.

Unique in its application of a mathematical model to understand how the brain transitions from consciousness to unconscious behavior, a study may have just advanced neuroscience appreciably. The findings, surprisingly by physicists, suggest that the subliminal state is the most robust part of the conscious network.

When scientists from different disciplines collaborate -- as is increasingly necessary to confront the complexity of challenging research problems -- interpersonal tussles often arise. One scientist may accuse another of stealing her ideas. Or, a researcher may feel he is not getting credit for his work or doesn't have access to important data. A free, online training tool, teamscience.net, has been proven to develop skills to work with other scientists outside their own discipline.

A team has identified a gene that could make immunotherapy treatments, specifically checkpoint inhibitors, work for a wider variety of cancer patients. The study found that when the DUX4 gene is expressed in cancer cells, it can prevent the cancer from being recognized and destroyed by the immune system.

Women have come a long way in the United States over the last 70 years, to the point where they are now seen as being as competent as men, if not more so, according to new research.

Researchers have identified a mechanism of how sleepy bacteria wake up. This finding is important, as sleepy cells are often responsible for the stubbornness of chronic infections. Findings reveal new perspectives on how to treat chronic infections, for example by forcing bacteria to wake up.

Ribosomes need regenerating. This process is important for the quality of the proteins produced and thus for the whole cell homeostasis as well as for developmental and biological processes. Biochemists and biophysicists have now watched one of the most important enzymes for ribosome recycling at work -- ABCE1 -- and shown that it is unexpectedly versatile in terms of structure.

The art of tattooing may have found a diagnostic twist. A team of scientists in Germany have developed permanent dermal sensors that can be applied as artistic tattoos. A colorimetric analytic formulation was injected into the skin instead of tattoo ink. The pigmented skin areas varied their color when blood pH or other health indicators changed.

The risk factors for stroke and dementia are the same, and a growing body of evidence demonstrates that preventing stroke can also prevent some dementias. Now, a group of experts is calling on the global community to come together to take action on preventing dementia by preventing stroke.

Researchers have identified how differences in the genetic sequence of the two main strains of the cancer-associated Epstein-Barr virus (EBV) can alter the way the virus behaves when it infects white blood cells.

Needing to ride in a wheelchair can put the brakes on myriad opportunities -- some less obvious than one might think. New research sheds light on the bias people have toward people with disabilities, known as 'ableism,' and how it shifts over time.
