Urban street networks, building density shape severity of floods

The design of streets and layout of buildings have an impact on a city's resilience in the face of increasingly severe floods brought on by climate change. Researchers look at buildings and other urban structures as physicists consider elements in complex material systems. With this insight, the researchers have developed a new approach to urban flood modelling and found their results helpful in analyzing city-to-city variations in flood risk globally. Read more ›

Self-adjusting brain pacemaker may help reduce Parkinson's disease symptoms

A small feasibility study found that an implanted device regulated by the body's brain activity could provide continual and improved treatment for the symptoms of Parkinson's disease (PD) in certain people with the disorder. This type of treatment, called adaptive deep brain stimulation (aDBS), is an improvement on a technique that has been used for PD and other brain disorders for many years. The study found aDBS was markedly more... Read more ›

Number of pediatric inpatient psychiatric beds in the U.S. did not increase 2017-2020 despite youth mental health crisis

U.S. pediatric inpatient psychiatric bed capacity did not change 2017 -- 2020, despite increases in pediatric mental health emergency visits, according to a new study . Researchers also found substantial geographic variation in inpatient psychiatric bed capacity per 100,000 children, ranging from zero in Alaska to 75 in Arkansas. Over 90 percent of pediatric inpatient beds are in urban centers, raising concerns for youth living in rural areas. Read more ›

Mining the microbiome: Uncovering new antibiotics inside the human gut

Researchers surveyed the gut microbiomes of nearly 2,000 people, discovering dozens of potential new antibiotics. The lead candidate, prevotellin-2, demonstrated anti-infective capabilities on par with polymyxin B, an FDA-approved antibiotic used today to treat multidrug-resistant infections, suggesting that the human gut microbiome may contain antibiotics that will someday find clinical application.

Research study examines Alzheimer's disease drug on tissue samples from people with Down syndrome

People with Down syndrome are likely to develop Alzheimer's disease at a young age, with autopsy studies showing that by age 40 years, the brains of individuals with Down syndrome have amyloid plaques. Yet people with Down syndrome have been excluded from or underrepresented in clinical trials of new therapies for treating AD. Read more ›

Spider exploits firefly's flashing signals to lure more prey

Fireflies rely on flashing signals to communicate to other fireflies using light-emitting lanterns on their abdomens. In fireflies of the species Abscondita terminalis, males make multi-pulse flashes with two lanterns to attract females, while females make single-pulse flashes with their one lantern to attract males. Now researchers have evidence that an orb-weaving spider (Araneus ventricosus) manipulates the flashing signals of male fireflies ensnared in its web such that they mimic... Read more ›

Nurses play key role in addressing mental well-being for people after a stroke

The latest research indicates that 16% to 85% of people recovering from a stroke experience at least one psychosocial symptom, including depression, anxiety, stress, fatigue and/or decreased quality of life. Critical nursing interventions, such as regular mental health screenings, education, symptom management and follow-up care, are key to reducing the negative effects on a patient's mental well-being after a stroke, yet only a small proportion of patients receive treatment.
