How we come to know our bodies as our own

A recent study has identified the brain regions responsible for our sense of body ownership, revealing a unified view of the body as a single entity. The findings suggest that multisensory neurons integrate visual, tactile, and proprioceptive information to facilitate full-body ownership.

Science explains ancient copper artifacts

Researchers at Northwestern University recreated ancient copper artifact-making techniques used by prehistoric Native Americans of Cahokia. They analyzed small pieces of discarded copper and determined that the coppersmiths likely hammered the copper with a heavy rock, then heated it in a wood fire to create thin sheets.

Why childhood obesity? It's so much more than what kids eat

The study examines various factors that contribute to childhood obesity, such as genetic predisposition, breastfeeding, TV watching, neighborhood environment, and cultural influences. The researchers have collected data from approximately 400 families and are beginning a third wave of data collection.

Counting on bigger mining returns

A new study developed by McGill Professor Roussos Dimitrakopoulos has created more accurate mine planning models that take into account uncertainty in the supply of minerals. This results in higher return on investment for mining companies while increasing metal production from the same asset.

Inside the infant mind

Researchers discovered that babies as young as 12 months old can use their knowledge of basic rules to form expectations about new events. A computational model accurately predicts infants' surprise at unexpected events, suggesting they reason by mentally simulating possible scenarios.

Virtual workout partners spur better results

Researchers from Michigan State University analyzed the Kohler effect in health video games and found that working out with a virtual partner improves task persistence and reduces social anxiety. The study suggests that incorporating design features based on the Kohler effect could motivate vigorous exercise.

Study links obesity to increased risk of developing postoperative infection following colon surgery

A study published in Archives of Surgery found that obese patients are at a significantly higher risk of developing surgical site infections after colectomy. The study also showed that these infections result in increased costs, lengthier hospital stays, and a higher rate of hospital readmissions. As pay-for-performance models penalize...

Adult-sized ATVs are not safe for kids; statistics startling

ATV-related injuries disproportionately affect children, with lower extremity fractures, partial foot amputations, and head injuries being common. The number of ATV-related deaths among children has increased dramatically over the past decade, highlighting the need for proper adult supervision, helmets, and age-appropriate vehicles.

Amphiphilic dendronized homopolymers

Researchers have synthesized a novel class of amphiphilic dendronized homopolymers with variable amphiphilicity, showing thermoresponsiveness and forming ordered porous films. These polymers adopt helical conformations in solution and can be used to develop new amphiphilic polymer structures.

Rapid etching X-rayed

Researchers at Kiel University developed a method to track atomic-scale changes during etching and coating, revealing uniform metal removal. The technique enabled detection of reactions within milliseconds, providing insights into industrially employed processes.
