New research reveals shark superhighways and hotspots

Researchers have discovered critical details of shark behavior, including migration routes and gathering sites. The findings suggest that open-ocean sharks are particularly threatened from overfishing, and that some species congregate at established 'stepping stone' sites, which can help inform conservation efforts.

Impacts of fossil fuels on fish and people

Scientists uncover toxic polycyclic aromatic hydrocarbons in air pollutants from fossil fuels, damaging fish hearts and potentially contributing to human cardiovascular diseases. This emerging threat highlights the need for further research on the impacts of urban air pollution on human health.

New findings on emerging contaminants

Researchers have found that 400 chemicals resist breaking down in the environment, affecting fish and wildlife, and potentially human health. The study also reveals pesticides can be more toxic when combined, threatening salmon populations and human health.

Using HEPA filters may improve cardiovascular health

Researchers found that using HEPA filters for two days significantly improved microvascular function in healthy, non-smoking elderly individuals. The study suggests that indoor air filtration could be a feasible means of reducing cardiovascular risk by removing ultrafine, fine and coarse air particles.

Tumor-targeting viral therapy slows neuroblastoma, malignant peripheral nerve sheath tumors

Researchers developed a tumor-targeting viral therapy that slowed the growth of neuroblastoma and peripheral nerve sheath tumors by inhibiting tissue growth and reducing blood vessel formation. The treatment, called rQT3, showed promise in laboratory studies and improved life spans in mice with these types of tumors.
