Study uncovers ‘concerning’ defect in malaria diagnosis – World News Network

According to a new study, current methods can greatly overestimate the rates at which malaria parasites multiply in an infected person's blood, which has important implications for determining how harmful they are to a host. The findings have ramifications for understanding how medicine resistance evolves, how rapidly a parasite spreads throughout a community, and the efficacy of new vaccines. The article, titled 'Extraordinary Parasite Multiplication Rates in Human Malaria Infections,' was published in the August issue of Trends in Parasitology.

Researchers discover possible cause for genetic anomalies – World News Network

Researchers have discovered a possible cause for the genetic anomalies that cause rare disorders such as Huntington's disease (HD). The majority of spinocerebellar ataxias (SCAs) and other neurological illnesses are thought to be caused by an increase in CAG (cytosine-adenine-guanine) repeats within a gene, which causes an expansion of the polyglutamine (polyQ) tract in a protein. Such illnesses are hereditary because the amplification of CAG repeats in a gene can be passed down across generations. It was previously thought that the harm caused by these inherited diseases was mainly due to an increase in protein aggregation toxicity. A recent study found a new source, c(RNA), that can produce the toxic amounts required to injure the brain in these disorders.

People who live alone are at danger of cognitive decline: Study – World News Network

One in every four older Americans with dementia or mild cognitive impairment lives alone, placing them at risk of dangerous driving, wandering outside the home, mixing up medications, and missing medical appointments. Researchers led by UC San Francisco determined in a study published in JAMA Network Open, that the United States health system is ill-equipped to support patients living alone with cognitive decline, a group whose numbers are expected to grow as the population age.
