Hematopoietic stem cell transplants may provide long-term benefit for people with MS

MINNEAPOLIS – A new study shows that intense immunosuppression followed by a hematopoietic stem cell transplant may prevent disability associated with multiple sclerosis (MS) from getting worse in 71% of people with relapsing-remitting MS for up to 10 years after the treatment. The research is published in the January 20, 2021, online issue of Neurology®, […]

Modern microbes provide window into ancient ocean — ScienceDaily

Step into your new, microscopic time machine. Scientists at the University of Colorado Boulder have discovered that a type of single-celled organism living in modern-day oceans may have a lot in common with life forms that existed billions of years ago — and that fundamentally transformed the planet. The new research, which will appear Jan. […]

Brain volume measurement may provide early biomarker — ScienceDaily

Posttraumatic stress disorder (PTSD) is a complex psychiatric disorder brought on by physical and/or psychological trauma. How its symptoms, including anxiety, depression and cognitive disturbances arise remains incompletely understood and unpredictable. Treatments and outcomes could potentially be improved if doctors could better predict who would develop PTSD. Now, researchers using magnetic resonance imaging (MRI) have […]

Ripples in space-time could provide clues to missing components of the universe

Almost everything fits, but there’s a fly in the cosmic ointment, a particle of sand in the infinite sandwich. Some scientists think the culprit might be gravity—and that subtle ripples […]

New method for imaging exhaled breath could provide insights into COVID-19 transmission

The new imaging technique has been used to capture the exhaled breath of a person speaking. This is a demonstration of the published imaging technique that is being further investigated. The imaging shows only the temperature change associated with exhaled breath, which does not necessarily reflect the movement of viral particles contained in the breath. […]
