Teaching pupils to 'think like Da Vinci' will help them to take on climate change
Reforms to the school curriculum which mix the arts and sciences, so that these subjects 'teach together' around common themes like climate change and food security, will better prepare young people for the real-world challenges that will define their adult lives, researchers argue in a new paper.

Use of e-cigarettes plus tobacco cigarettes linked to higher risk of respiratory symptoms
Using both e-cigarettes and tobacco cigarettes may increase the risk of developing respiratory symptoms--such as cough and wheeze--compared with using either alone. Dual users had a 1.9-times higher odds of developing respiratory symptoms compared with exclusive e-cigarette users and a 1.24-times higher odds compared with exclusive tobacco smokers.

Life satisfaction among young people linked to collectivism
An international group of scientists from Italy, the USA, China and Russia have studied the relationship between collectivism, individualism and life satisfaction among young people aged 18-25 in four countries. They found that the higher the index of individualistic values at the country level, the higher the life satisfaction of young people's lives.

Taking down human traffickers through online ads
Researchers at Carnegie Mellon University and McGill University have adapted an algorithm first developed to spot anomalies in data, like typos in patient information at hospitals or errant figures in accounting, to identify similarities across escort ads. The algorithm scans and clusters similarities in text and could help law enforcement direct their investigations and better identify human traffickers and their victims, said Christos Faloutsos, the Fredkin Professor in Artificial Intelligence at CMU's School of Computer Science, who led the team.

Law professor argues for removing police from traffic enforcement
In "Traffic Without Police," University of Arkansas law professor Jordan Blair Woods articulates a new legal framework for traffic enforcement, one that separates it from critical police functions, such as preventing and deterring crime, conducting criminal investigations and responding to emergencies.

What Parkinson's disease patients reveal about how art is experienced and valued
Altered neural functioning, like that experienced in patients with Parkinson's disease, changes the way art is both perceived and valued. People with neurological motor dysfunction demonstrated decreased experiences of motion in abstract art and enhanced preferences for high-motion art, compared to a healthy control group.

Army-funded research paves way for improved lasers, communications
New photonics research paves the way for improved lasers, high-speed computing and optical communications for the Army. Using light's speed and the way information can be layered in its various physical properties can increase the speed of communication while reducing wasted energy; however, light sources such as lasers need to be smaller, stronger and more stable to achieve that, researchers said.

Pregnant women with COVID-19 face high mortality rate
In a worldwide study of 2,100 pregnant women, those who contracted COVID-19 during pregnancy were 20 times more likely to die than those who did not contract the virus.

Ancient Indigenous forest gardens promote a healthy ecosystem: SFU study
A new study by Simon Fraser University historical ecologists finds that Indigenous-managed forests--cared for as "forest gardens"--contain more biologically and functionally diverse species than surrounding conifer-dominated forests and create important habitat for animals and pollinators.

Scientists unmask new neutralizing antibody target on SARS-CoV-2 spike protein
Researchers have identified another potential target for neutralizing antibodies on the SARS-CoV-2 Spike protein that is masked by metabolites in the blood. As a result of this masking, the target may be inaccessible to antibodies, because they must compete with metabolite molecules to bind to the

Scientists uncover a molecule that can help coronavirus escape antibodies
Researchers have found that a natural molecule can effectively block the binding of a subset of human antibodies to SARS-CoV-2. The discovery may help explain why some COVID-19 patients can become severely ill despite having high levels of antibodies against the virus.

International research teams explore genetic effects of Chernobyl radiation
Researchers utilized genomic tools to investigate potential health effects of exposure to ionizing radiation, a known carcinogen, as a result of the 1986 Chernobyl accident. One study found no evidence that genetic changes associated with radiation exposure are passed to children, while the second study documented the genetic changes in the tumors of people who developed thyroid cancer after being exposed as children or fetuses to the radiation released by the accident. Findings are being published close to the 35th anniversary of the Chernobyl disaster.

Researchers trace spinal neuron family tree
Spinal cord nerve cells branching through the body resemble trees with limbs fanning out in every direction. But this image can also be used to tell the story of how these neurons, their jobs becoming more specialized over time, arose through developmental and evolutionary history. Salk researchers have traced the development of spinal cord neurons using genetic signatures and revealed how different subtypes of the cells may have evolved and ultimately function to regulate body movements.
