Worms under stress
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.

New Orleans 'toxic soup' a less serious problem than initially believed
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.
People prefer belonging to groups in which members can punish freeloaders
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.
Environmental crisis forging strange bedfellows
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.
Engineering progress could cut pollution
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.
Household activities release a cloud of dust, increasing exposure to particulate pollution
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.
Sand-mud model could predict effects of opening sluices
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.
Nanotechnology: sink or swim?
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.
Sensor will save energy, reduce pollution, engineer says
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.
