Are leaders born or made? New study shows how leadership develops

Researchers at the University of Illinois College of Agricultural, Consumer and Environmental Sciences conducted a new study on leadership development. The study found that leadership development progresses in three stages: readiness, willingness, and ability. Students who develop these skills can become effective leaders. Leadership i...

Stigma can hinder access to health care for the poor

A study of 574 low-income adults found that stigma while receiving medical care was associated with unmet health needs and poorer perceptions of quality. Experiencing stigma led to worsening self-reported health despite equal use of healthcare services.

Are Montana's invasive fish in for a shock?

A new study suggests that electrofishing can effectively remove non-native Brook Trout from small Rocky Mountain streams, preserving native Westslope Cutthroat Trout populations. The method involves using electrical shock to target and remove specific unwanted species, reducing impacts on native fish and macro-invertebrates.

Nanoparticles break the symmetry of light

Physicists at Vienna University of Technology have developed an optical switch using spin-orbit coupling of light. By employing gold nanoparticles coupled to ultra-thin glass fibers, they can emit light into the fiber in a way that does not travel in both directions, but instead is directed either left or right.

Discovery of a novel heart and gut disease

Scientists have identified a novel heart and gut disease, named Chronic Atrial Intestinal Dysrhythmia syndrome (CAID), caused by a rare genetic mutation. The disease is characterized by cardiac arrhythmias and intestinal pseudo-obstruction, with patients often requiring invasive treatments and surgeries.

Scientists develop barcoding tool for stem cells

Researchers at Harvard University developed a barcoding tool to track the origin of blood cells, revealing that progenitor cells, not blood stem cells, give rise to specific blood cell types. This discovery challenges scientific dogma and has potential applications for blood regeneration therapies.

Alcohol consumption associated with increased risk of HPV infection in men, say Moffitt researchers

A recent study by Moffitt Cancer Center researchers found that men who consume more alcohol have a significantly higher risk of human papillomavirus (HPV) infection. The study analyzed over 1,300 men and discovered that those who drank the most alcohol had an increased risk of HPV independent of their number of sexual partners.

Argonne researchers create more accurate model for greenhouse gases from peatlands

A new model developed by Argonne National Laboratory scientists predicts that peatlands in the Arctic will release more methane and less carbon dioxide as they warm, significantly affecting climate change forecasts. The research aims to improve greenhouse gas emission models and address concerns about accelerated warming in the Arctic.

New study finds lack of adherence to safe handling guidelines for administration of antineoplastic drugs

A National Institute for Occupational Safety and Health (NIOSH) study found that nearly 2,100 oncology nurses and healthcare personnel do not always follow recommended safe handling practices for antineoplastic drugs. The lack of adherence increases exposure risk to cancer-causing agents, leading to adverse health outcomes.
