Researchers used mathematical modeling tools to document the spread of sea lice from commercial salmon farms to wild Pacific salmon. The study found that a single farm could lead to a massive increase in parasite load, affecting the health of young fish.
Researchers found that newborns (10-72 hours old) prefer speech over nonsensical words in a study led by Dr. Athena Vouloumanos. The infants showed increased sucking behavior when hearing human speech compared to speech-like analogues, suggesting an experience-independent component to their preference for speech.
The emerald ash borer's invasive beetle population is rapidly spreading in Ontario's ash forests, despite containment efforts. The insect's distribution expanded dramatically in 2004, infecting new sites beyond a previously created firewall in Essex County.
Researchers have discovered evidence of barren ground grizzly bears on Melville Island, a remote area in the western Arctic. The presence of these bears is significant as they are known to prey on polar bear cubs and could potentially disrupt the balance of Arctic ecosystems.
Dr. Brooks' research highlights the link between biodiversity decline and emerging human and wildlife diseases, such as West Nile Virus and avian flu. He argues that understanding parasite life cycles is crucial to preventing these diseases.
A bird IQ test, developed by Dr. Lefebvre, ranks species based on their innovative feeding behaviors observed in the wild. The study found that birds with greater behavioral flexibility and larger forebrains are more successful in new environments.
Despite advances in molecular biology, microbes have outpaced pharmaceutical companies in developing resistance to antibiotics. Dr. Julian Davies highlights over 300 known genes that confer resistance, and notes the need for a deeper understanding of microbial evolution.
Scientists are restoring the marshes of Eden in southern Iraq, which were devastated under Saddam Hussein's rule. The project aims to rebuild wetland ecosystems and reacquaint local experts after two decades of isolation.
Dr. Felix Herrmann proposes a new theory that seismic data may be showing a simpler interplay of only two substances, rather than complex mineralogies, allowing for clearer images and better understanding of the Earth's interior structure. This approach could lead to improved oil patch discovery and enhanced geological resolution.
Researchers suggest introducing a new species to balance ecosystem health and mitigate the risk of farmed fish escapes. Dr. Ian Fleming argues that this could be a solution to limit ecological impact.
Dwarf mistletoe has an extreme water-pump seed ejection system that fires seeds up to 20 meters. This discovery could aid disease control by targeting the unique characteristics of dwarf mistletoe reproduction.
Researchers from the Collaborative Mercury Research Network (COMERN) are conducting a unique experiment to test whether old-fashioned tea can prevent mercury absorption. In this study, participants will eat local Lake Winnipeg fish with or without black tea for three days, and provide blood samples to track mercury levels.
Researchers developed an experiment to measure the behavior of curling stones, revealing that wet friction is involved in their curl. The study found that a thin liquid layer reverses the dominant frictional force on the stone, resulting in a clockwise-turning stone curling to the right.
A study found that preschool children's storytelling skills are linked to their later math abilities, particularly their ability to relate events and switch perspectives. The research suggests that building strong storytelling skills early on may help prepare children for math when they enter school.
Scientists uncover proof Frobisher's assayers intentionally added gold to worthless black rocks, fueling an investment frenzy. Lead samples analyzed for the first time show no contamination, confirming a massive fraud.
A study found that 45 first-year psychology students reported elaborate false memories of a fictional event after being told three stories about their grade-school experiences. The presence of a real class photo doubled the rate of false memories compared to studies without photographs.
