Finding treatments for advanced multiple sclerosis (MS) has been difficult. But new research may help neurologists identify which drugs are best for people with the advanced form of MS called secondary progressive MS. The new study, published in the June 30, 2021, online issue of Neurology®, the medical journal of the American Academy of Neurology, found that the more potent disease-modifying drugs are more effective in reducing flare-ups in secondary progressive MS than the less potent drugs that tend to be safer to take. However, the researchers found no difference in how fast the disease progressed between these two types of drugs.

A new study suggests that even when differences in socioeconomic status are taken into consideration, Black people with multiple sclerosis (MS) may be more negatively impacted by the disease than white people with MS. The research is published in the June 30, 2021, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study found that Black people with MS had lower scores on certain measures of neurological health, like dexterity and walking tests and showed more evidence of disease progression on brain scans.

Researchers at Texas Biomedical Research Institute (Texas Biomed) have narrowed down the proteins enabling SARS-CoV-2 to cause disease. Using advanced genetic engineering techniques developed at Texas Biomed, they systematically deleted the genetic code for five of the virus’s accessory proteins, one at a time, to see how each one affected the virus’s ability to spread and cause illness. The research was published online this month in the Journal of Virology.

A study is the first to examine the relationship between grit and a muscular endurance performance task – specifically, the grueling back squat. The expectation was that a “gritty” person would perform more repetitions in a resistance training set. Interestingly, grit did not predict muscular endurance during the back squat in well-trained men and women. Both males and females independently failed to show a relationship between grit and repetitions performed.

Phosphorus is a building block of all living cells. Most phosphorous occurs in the form of phosphate, but ancient oceans and soils also contained another form, phosphite. Microbes gain energy by converting phosphite to phosphate via phosphorous reduction-oxidation (redox) cycling. A new study suggests that the ability to use phosphite in energy metabolism is surprisingly widespread in nature.
