The study found that otters are more common in areas with moderate human impact, where water quality has improved and prey species like fish and crayfish are abundant. The researchers suggest conserving aquatic habitats to encourage greater distribution of the species.
The Lancet Editorial highlights how aid agencies often prioritize their own interests over helping individuals, with a focus on raising funds and media coverage. This critique emphasizes the need to examine the industry's operations, beyond financial scrutiny.
A study found that at least 85% of computers imported into Peru are reused, rather than going directly into recycling. The US is the source of up to 76% of used computers imported to Peru, challenging the widespread belief that e-waste is mainly about dumping unusable junk.
Long-term research reveals a quarter-century of data on penguin numbers, showing a decline of over 20 percent in the last 22 years. Penguins are struggling with food scarcity, leading them to nest outside protected areas where they fall prey to predators.
A DNA test can detect harmful algal blooms across the globe, reducing economic impact on fisheries, recreational activities, and aquaculture sites. Factors such as climate change and pollution contribute to algal bloom occurrences.
Dental amalgam's use is being restricted due to mercury concerns, but scientific evidence suggests a link between the two is unclear. The move may remove a viable treatment option for dentists and patients worldwide.
A new model developed by Dr. Sam Brown recognizes the impact of durable goods on cooperation, showing that cheaters can increase without immediate consequences but ultimately face costs when others follow suit. This research has far-reaching implications for fields like ecology, economics, and medicine.
Researchers found nematodes' life cycle affects pollution sensitivity, with sexually-reproducing strains more vulnerable. Temperature changes trigger genome shifts and alter gene regulation, impacting population growth.
Recent studies have found that levels of toxic metals in New Orleans soil samples were not significantly higher than before Hurricane Katrina. In fact, some pollutants may have decreased due to natural processes. Researchers are now focusing on restoring the Gulf Coast's resilience through science and engineering.
A study found that individuals prioritize groups with punishment options over those without, leading to increased cooperation and financial rewards. This discovery may contribute to a general theory of human cooperation and inform strategies for addressing global issues like climate change.
A professor of environmental studies at U of T is bridging the gap between science and religion to address the environmental crisis. He notes that some religious yet ecology-minded Republicans are involved in a campaign against gas-guzzling SUVs, asking Americans to consider more ecologically sensitive cars.
Researchers at Cardiff University have developed new combustion processes that could significantly reduce pollution, thanks to a collaborative project with the University of Adelaide. The project uses advanced laser diagnostics to improve models for alternative fuel mixes.
A study by Andrea Ferro found that common household activities like dusting, vacuuming, and even walking around can resuspend house dust, increasing exposure to particulate pollution. This can aggravate health problems like asthma and decrease lung functioning.
Researchers developed a model to calculate movements of both sand and mud in tidal areas, revealing locations with little sedimentation due to quick water flow. The model can predict the effect of human intervention in tidal waters, addressing questions about released polluted mud layers and ecosystem changes.
The report provides a sober assessment of nanotechnology's possibilities, distinguishing between current applications, potential future advancements, and unfeasible goals. It also explores the role of social science in nanotechnology development, highlighting opportunities to anticipate and incorporate implications into the technology.
A new optical laser sensor will reduce energy consumption by up to 30% and greenhouse gas emissions in the steel industry. The sensor, developed at the University of Toronto, measures thermal and chemical energy losses and adjusts parameters to lower energy consumption.
