Flair Used in r/science
#1
Health
: "Replacing gas stove can help asthmatics as much as some drugs. Swapping to electric has ‘very large’ impact, despite study being scaled back by Trump cuts. 70% drop in hospital admissions and days off from work or school when people with poorly controlled asthma had gas stove replaced with electric."

Psychology
: "People with ADHD have difficulties with goal-directed behavior and struggle with response inhibition, the ability to stop an inappropriate action once they feel the urge to do it. They experience a disruption in the way their brains balance deliberate self-control and automatic habit learning."

Environment
: "Scientists have, for the first time, genetically engineered lettuce and tobacco plants to grow the animal protein myoglobin. Plant-derived myoglobin could achieve protein yields per hectare that rival – or even exceed – those of animal agriculture, with lower water use and greenhouse gas emissions."

Social Science
: "A political science paper has emerged comparing the political career of U.S. President Donald Trump to the narrative of Japan’s iconic monster, Godzilla. The study highlights parallels: both were summoned by human errors, wreak havoc indiscriminately, and return even after being seemingly defeated."

Neuroscience
: "Autism diagnoses rose sharply after the COVID-19 pandemic began. The rise was driven overwhelmingly by diagnoses among girls and women. New study suggests that many of these girls and women may simply have gone unrecognized in the past."

Medicine
: "Scientists stumped to find clearing cholesterol from blood also removes forever chemicals from body. A blood-filtering technique for lowering cholesterol may also remove toxic forever chemicals from the body, a new study suggests."

Biology
: "In lab tests, salmonella, E. coli and staph survived 14+ days in kitchen sponges — 3 days after drying out — and one wipe moved up to 100,000 bacteria to a clean surface; smell and color gave no indication of contamination. Brushes dry faster and carry far fewer bacteria, researchers say."
