Formation and large scale confinement of jets emitted by young stars finally elucidated

Researchers from around the world have successfully explained the formation and propagation of stellar jets emitted by young stars. The team used a patented experimental device and numerical simulations to demonstrate that interstellar magnetic fields play a key role in confining these jets, which can travel vast distances.

Extinct giant kangaroos may have been hop-less

New research suggests that extinct giant kangaroos likely walked instead of hopped, with stiff backs and strong joints supporting their body posture. The study analyzed anatomical differences in limb bones compared to other kangaroo species.

Grant to help find why people reveal information online

Penn State researchers are teaming up to study how certain cues on mobile and web devices inspire mental shortcuts that predict user trust in online sites and social networks. The study aims to promote better interface design and educate users about mental shortcuts that compromise their privacy when online.

Evolution of snake courtship and combat behavior

Researchers identified patterns in courtship and male-to-male combat behaviors across 70 snake species, revealing evolutionary relationships between behaviors. The study found that different clades developed unique behaviors, such as coiling without neck-raising and body-bridging, which replaced earlier toppling behavior.

IU researchers isolate process that damages lungs of donors with traumatic brain injury

Researchers at Indiana University have isolated a process that damages the lungs of donors who suffered from traumatic brain injury, which may lead to improved lung transplant outcomes. The study found that fluid accumulation in the lungs occurs within hours after head trauma, limiting oxygenation and reducing lung function by nearly 80%.

In sync and in control?

A study by UCLA social scientists found that men who march in unison with others perceive a potential foe as smaller and less intimidating, leading to increased feelings of power and aggression. The researchers theorize that this phenomenon may be an evolutionary adaptation that favors individuals moving in coordination with groups.
