Harmful hospital bacteria evolved ‘in response to modern diets’

Clostridioides difficile is a form of bacteria that typically infects patients in hospital environments after they have received antibiotic therapy that has upset the bacterial balance in their guts. New research explains how this bacterium is evolving and suggests new ways forward in prevention and therapy. C. diff. may have evolved in line with the […]

Schizophrenia: Genes related to circadian rhythms may be disrupted

New research examines the brains of people with schizophrenia and finds disrupted patterns of expression in genes linked with sleep-wake cycles. New research into schizophrenia finds disruptions in the rhythmicity with which some genes are expressed in the brain. Worldwide, schizophrenia is one of the top 15 leading causes of disability, affecting about 1% of […]

Study reveals 6 top exercises for offsetting ‘obesity genes’

New research examines the effect of 18 different kinds of exercise on people with a high genetic risk of developing obesity. The findings identify six exercises that can offset the genetic effects on five measures of obesity. Several types of exercise can prevent obesity in people genetically prone to the condition, new research shows. According […]

ALS: ‘Unique’ cells could open up new avenues for therapy

Amyotrophic lateral sclerosis, or ALS, is a progressive neurodegenerative disease that leads to the death of nerve cells that control movement, leaving people unable to move and, eventually, to breathe. ALS is fatal and, so far, incurable. Can new findings bring hope for novel therapies? New research finds previously unknown subtypes of motor neurons in […]

New psychosis treatment targets genetic mutation instead of symptoms

A novel treatment that targets the biological effects of a specific genetic mutation could help alleviate the symptoms of psychosis, a new study finds. Targeting one genetic mutation helped scientists devise an innovative treatment for psychosis. Deborah L. Levy, Ph.D. — from the McLean Hospital in Belmont, MA — led the new study, the findings […]

New research may explain why evolution made humans ‘fat’

Scientists have compared fat samples from humans and other primates and found that changes in DNA packaging affected how the human body processes fat. Evolution made humans the ‘fat primate,’ researchers suggest. Our bodies need fat to store energy and protect vital organs. Fat also helps the body absorb some nutrients and produce important hormones. […]
