Short-term exposure to low levels of air pollution linked with premature death among U.S. seniors
Short-term exposures to fine particulate air pollution and ozone—even at levels well below current national safety standards—were linked to higher risk of premature death among the elderly in the U.S. according to a new study from Harvard T.H. Chan School of Public Health.
The risk was even higher among elderly who were low-income, female, or Black.
The study was published December 26, 2017 in the Journal of the American Medical Association (JAMA).

Charcoal remains after a forest fire help decompose fine roots in the soil, potentially accelerating CO2 emissions in boreal forests.
A simple solution for terrible traffic
Cities plagued with terrible traffic problems may be overlooking a simple, low-cost solution: High-occupancy vehicle (HOV) policies that encourage carpooling can reduce traffic drastically, according to a new study co-authored by MIT economists.
A New Strategy for Efficient Hydrogen Production
A joint research team, affiliated with UNIST has introduced the Hybrid-Solid Electrolysis Cell (Hybrid-SOEC) system with highest reported electrochemical performance in hydrogen production. The proposed system has attracted much attention as a new promising option for the cost-effective and highly-efficient hydrogen production, as it shows excellent performance compared with other water-electrolysis systems.
Una solución simple para el tráfico terrible
Las ciudades plagadas de terribles problemas de tráfico pueden estar pasando por alto una solución simple y de bajo costo: las políticas de vehículos de alta ocupación (HOV) que fomentan el uso compartido de automóviles pueden reducir el tráfico drásticamente, según un nuevo estudio en coautoría de economistas del MIT.
