According to the results of a new study published in the journal The Lancet, more than 1 million people died from antibiotic-resistant infections across the globe in 2019, hundreds of thousands more than malaria or HIV/AIDS.  Antimicrobial-resistant bacteria are considered one of the biggest threats facing modern medicine. Some studies have even estimated that by […]

The random occurrence of mutations with respect to their consequences is an axiom upon which much of biology and evolutionary theory rests. This simple proposition has had profound effects on models of evolution developed since the modern synthesis, shaping how biologists have thought about and studied genetic diversity over the past century. New Study Challenges […]

MS is a chronic immune-mediated demyelinating and neuroinflammatory disease of the brain and the spinal cord that can result in neurological dysfunction and disability.  Focal white matter lesions (WML) of demyelination are the most readily detectable manifestation of multiple sclerosis at morphologic MRI. However, they represent only macroscopic tissue damage and are therefore unable to […]

The first of its kind surgery was successfully completed in a 57-year-old patient with terminal heart disease. He received a transplant from a genetically-modified pig heart. The team of surgeons was from the University of Maryland School of Medicine in Baltimore. The organ transplant demonstrated for the first time that a genetically-modified animal heart can […]

A new study by researchers from the Johns Hopkins University Bloomberg School of Public Health has identified a bacterial protein associated with colorectal cancers. The newly identified toxin common in E. coli bacteria accelerated colon cancer in a mice study, which confirms a link to human colorectal cancers and could pave the way for developing […]

The body’s glucose levels are regulated by different hormones produced by the pancreas. The main one, insulin is produced to regulate the amount of sugar circulating in the blood.  In diabetes, this mechanism starts failing either when the pancreas fails to produce enough insulin or when the body’s tissues become resistant to the hormone’s effects.
