Hearing changes how we perceive gender

A Northwestern University study found that tones of voices can alter visual processing, suggesting a direct input from early auditory processing to visual perception. Researchers used pure tones to test whether sounds can influence perception of face gender, with results showing bias towards male or female faces based on tone frequency.

New pediatric research

Uncontrolled asthma is linked to significantly more school and work absences, with a new study showing up to 2-3 times more days absent. Antismoking classes may improve young children's knowledge about tobacco smoke, while phone triage programs provide safe and cost-effective care for ventilator-dependent children.

The conservation lens

A team of researchers explored sub-Antarctic ecosystems to estimate the diversity of tiny bryophytes and lichens, finding a hotspot for these organisms. The study emphasizes the need for conservation strategies that integrate non-vascular plants beyond charismatic mega fauna.

Early predictive model may be new 'weapon' against leading cause of death on battlefield

A new predictive model using hemoglobin level, International Normalized Ratio, and penetrating injury mechanism can accurately predict which soldiers require massive blood transfusions, allowing for timely mobilization of resources. This model has been shown to reliably predict the need for massive transfusions in combat patients.

Living with lions

In Cameroon's Waza National Park, people have learned to coexist with lions, weighing the benefits of closer grazing against the risk of losses. Researchers found that despite the risks, herdsmen continue to live near the park due to improved access to pastures and water.

Colorful view for first land animals

A study published in BMC Evolutionary Biology found that ancient fish, specifically Australian lungfish, had retinas with visual pigments similar to those of early four-legged vertebrates. This suggests these creatures may have seen their new environment in full color when they first emerged onto land.

Decline in uptake of carbon emissions confirmed

A recent study confirms that the proportion of carbon dioxide emissions absorbed by land and oceans is declining, leading to a faster increase in atmospheric CO2 levels. This trend has major implications for climate modeling and highlights the need to reduce global emissions to mitigate climate change.

Fewer adverse cardiac events at one year

The SPIRIT III trial found that the Xience V everolimus-eluting coronary stent significantly reduced major adverse cardiac events, including heart attacks and deaths from cardiac causes, by 50% after 12 months compared to the Taxus paclitaxel-eluting stent. This reduction in events is an important finding for patients with heart disease.

An accurate method for preoperative diagnosis of pancreatic solid pseudopapillary tumor

A novel technique of image-guided fine-needle aspiration (FNA) using endoscopic ultrasound (EUS) guidance is introduced for accurate preoperative diagnosis of pancreatic solid pseudopapillary tumors. This method helps differentiate SPTP from other pancreatic neoplasms with different biologic behavior and treatment.

Sexual knowledge and attitudes of men with intellectual disability who sexually offend

Researchers investigated whether individuals with intellectual disabilities who commit sexual offenses have poorer sexual knowledge than those who do not. The study found that Type I offenders, characterized by deviant ideas about sexuality, had more sexual knowledge than a matched group of non-offenders. In contrast, Type II offenders...

Bus scheduling algorithm picks up the slack

A new bus scheduling algorithm, developed by a University of Southern California engineer, aims to reduce waiting times and improve transit reliability. The algorithm analyzes the impact of slack time on buses and finds that building in between 15 and 20 percent slack time is optimal, depending on total round trip travel time.

Social stress + darkness = increased anxiety

Researchers found that darkness amplifies the impact of social stress on anxiety levels, with a startle response boosted in healthy volunteers. The study suggests that stress can alter nervous system function and contribute to anxiety disorders.

AMIHOT II trial data presented at TCT

The AMIHOT II trial found that infusing oxygen-saturated blood into the previously blocked artery after an angioplasty procedure significantly reduced the size of the 'infarct zone', or damaged heart tissue. The study showed a 6.5% reduction in infarct zone size and no significant increase in Major Adverse Cardiac Events at 30 days.
