Tackle and scrum should be banned in school rugby, argue experts

A recent evidence review found that collision sports, such as youth rugby, carry high rates of injury, including concussions. Experts argue that banning tackle and scrum in school rugby could significantly reduce these risks. In contrast, other strategies like wearing protective equipment have weak evidence supporting their effectiveness.

Four elements make 2-D optical platform

Researchers at Rice University have discovered a four-component alloy with tunable optical properties, which could lead to more efficient solar cells and light-emitting diodes. The alloy's optical bandgap can be altered by changing the growth temperature, making it a promising material for various applications.

Filter may be a match for fracking water

Researchers create a superhydrophilic filter that can remove greater than 90% of hydrocarbons and all bacteria from contaminated water produced by hydraulic fracturing operations. The filter significantly cuts the amount of water that needs to be stored or transported, making it ideal for reusing in fracking operations.

Tension makes the heart grow stronger

Researchers found that mechanical tension plays a crucial role in the regeneration of zebrafish hearts, with supersized cells leading the way and smaller cells multiplying to cover the surface. The study's findings open up new possibilities for developing bioengineering approaches to human heart disease.

Prenatal weight talks are easier with props

A new study by Allina Health found that using a combination of education and a tracking tool improves communication about gestational weight gain during prenatal care. Patients at intervention clinics were more likely to remember provider advice on weight gain and report a target weight within guidelines.

Brain damage in fish affected by plastic nanoparticles

A recent study conducted at Lund University has found that brain damage can occur in fish due to exposure to plastic nanoparticles. The research shows that these tiny particles can accumulate in the brains of fish and cause behavioural disorders, including slower eating rates and reduced exploration.

Autism's gender patterns

The largest study to date finds a significant difference in autism recurrence risk based on sibling gender. Boys are more susceptible to autism, especially when an older female sibling has the condition. Meanwhile, female siblings with older brothers have lower risks.

Study examines legacies of rainforest burning in British Columbia

Researchers found that indigenous groups intentionally used fire to manage plant-life in temperate rain forests, leaving trees alive and keeping the forest open. The study suggests that this practice has been ongoing for centuries, contradicting traditional views of these forests as 'pristine' and 'untouched'.

Escaping wildfires

Researchers developed a mapping tool to help fire crews make crucial safety decisions with an eagle's eye view. The study used LiDAR technology to analyze terrain slope, ground surface roughness and vegetation density, revealing the impact on travel rates and escape route efficiency.
