라디오에서, 노래를 듣다가 끊으면 이게 미결상태로 남아서, 끝내기 위해 계속 다시 생각이 난다는 연구 소개. 머리를 꽉 채우는 스도쿠 같은 일을 해서 미결 상태인 생각을 밀어내면 효과가 있다고 한다. 미결 연애의 문제도 그런 것인가??
독일을 유로존에서 탈퇴시키려는 정당 대표 인터뷰. 마르크화로 돌아가자는 운동의 일환이고 인터뷰에 응한 이는 경제학 교수라 함. 유로화 위기는 유럽경제 생산성이 올라가지 않는 한 해결되지 않을 문제로 본다. 결국 깨질 것이라 예상..
Climate change may be happening more slowly than scientists thought. But the world still needs to deal with it

이건 포드캐스트로도 나왔는데, 지난 10년 혹은 50년 간 CO2 농도 증가에 비해 평균 기온 상승이 미미하거나 정체. 단위 농도 증가에 대해 온도 상승도 3+-1.5 로 보통 얘기했는데 2.5 나 2 +-1.5 로 조정되고 있고, +4.5 같은 극단적인 시나리의 가능성이 희박해졌다 평가. 그래서 느려졌다고 하는데, 이게 어떤 의미고 어떻게 하는게 좋겠냐 대담하고 등등.
Issues in Ecology #17, Ecological Dimensions of Biofuels

We conclude:
Estimated net GHG emissions from biofuels production can be lower than those of fossil fuels. However, this is highly dependent on feedstock (raw material) choice, fuel and fertilizer inputs, whether biofuel crops replace native vegeta- tion, and whether the soil is tilled. Further, emissions estimates for a given feedstock vary among studies, contributing to uncertainty about GHG effects.
The effects of biofuels production on water supply and quality are a function of the feedstock choice and production method. High intensity agricultural crops such as fertilized and irrigated corn can contribute nitrogen and phosphorus pollution to adjacent waterways and downstream, and can place substantial demands on regional water supplies. Perennial cellulosic crops such as switchgrass and mixed prairie grasses can substantially reduce these impacts.
Today’s grain-based biofuel crops compete with food crops for prime agricultural land. Pressure is growing to expand grain-based biofuels production onto marginal agricultural lands or land currently in the U.S. Department of Agriculture (USDA) Conservation Reserve Program. These lands support diverse wildlife communities and conver- sion is likely to affect some species of concern. Land conversion is also a major source of GHG production, especially when native habitats are destroyed. Land use impacts can be reduced by selecting feedstocks that do not displace food crops or require conversion of native habitats for production.
Impacts on wildlife abundance and diversity depend on the feedstock choice and whether production takes place on existing agricultural lands or on newly cleared land. At a landscape scale, more diverse feedstock crops are associated with greater biological diversity, while monocultures decrease it. Some plants being considered as sources of biofuels are potentially invasive, requiring consideration of potential impacts on habitats adjacent to the biofuels crop.

Eco informatics 표현을 써서 들여다 봤는데, 음.. 잘 부각되진 않는 것 같다. 헬싱키 대학에 여튼 랩이 있는 모양. 우리 학교에도 있는데 좀 다른 것 하는 과였음. 분자생물학.

Thousands of children are taking part in an online activity and survey to explore the links between nutrition, exercise and sleep and children's cognitive functions. There is a growing body of scientific research examining the links between lifestyle and learning. This video looks at the key findings as well as showing how a better understanding of brain function is helping teachers in the classroom
