Classroom talk plays a key part in the teaching of writing, study shows

The way teachers manage classroom discussion with pupils plays a key role in the teaching of writing, a new study shows. The research shows the importance of managing classroom discussion in a way that develops pupils’ understanding of the choices that writers make, and how those choices create particular effects for readers. This discussion helps pupils to think more about the choices that they make in their own writing. The study reinforces the importance of dedicating time to discussion in secondary English lessons. It shows that time should be given to exploratory, speculative discussion that ...

Compelling data point to a single, unknown respiratory virus as cause of Kawasaki disease

Research from Stanley Manne Children’s Research Institute at Ann & Robert H. Lurie Children’s Hospital of Chicago strongly suggests that Kawasaki disease is caused by a single respiratory virus that is yet to be identified. Findings contradict the theory that many different pathogens or toxins could cause this disease that can lead to serious cardiac complications in young children. “The cause of Kawasaki disease has been a mystery for over 50 years,” said Anne Rowley, MD, pediatric infectious diseases expert and scientist at Manne Research Institute at Lurie Children’s, who is the lead author on the study published ...

Melting ice, more rain drive Southern Ocean cooling

In brief Surface waters in the Southern Ocean have been cooling in recent decades, counter to what climate models predict. Scientists have quantified how much of the cooling observed since 1990 has been driven by an influx of freshwater that’s unaccounted for in state-of-the-art climate models. The researchers discovered that freshwater inputs along the coast from melting ice sheets exert surprisingly strong influence on Southern Ocean surface temperatures and the broader climate system.   Global climate models predict that the ocean around Antarctica ...

Rideshare data reveal discriminatory policing for speeding in Florida

Using data on more than 220,000 individuals on the Lyft rideshare platform, researchers report that drivers of color are significantly more likely to receive speeding tickets than white drivers, and to face steeper fines, even when traveling at identical speeds. Racial profiling by law enforcement is a pressing social issue in the United States. Previous research analyzing police and judicial records suggests that racial and ethnic minorities face disproportionately higher rates of searches, fines, force, detentions, and incarceration compared to white civilians. However, research on racial bias in policing has long been hindered by data limitations ...

Dopamine-producing brain circuit drives eating “for pleasure” in mice

A previously overlooked dopamine-producing brain circuit drives hedonic eating, or eating for pleasure, according to a new study in mice. The findings offer insights into how GLP-1 agonist drugs like semaglutide affect appetite suppression and why pleasing and delicious foods can override these drugs’ effects. In a related Perspective, Dana Small argues that the findings indicate that the inter-individual differences in the adaptation of this circuit in response to GLP-1 drugs may account for differences in treatment efficacy in humans. “Future work that aims to minimize such adaptation could offer a promising avenue for the development of ...

Park entrances may be hotspots for infective dog roundworm eggs

In an analysis of soil samples from twelve parks in Dublin, Ireland, park entrances were more heavily contaminated with infective roundworm eggs than any other tested park location. Jason Keegan of Trinity College in Dublin, Ireland, and colleagues present these findings in the open-access journal PLOS Neglected Tropical Diseases. Dogs and cats are often infected with parasitic roundworms in the Toxocara genus. Infected animals can release the roundworm eggs into the environment, and humans can become infected after accidental ingestion of the eggs. Many infected humans never experience symptoms, but some may experience mild or severe ...
