Levels of "background ozone" -- ozone pollution present in a region but not originating from local, human-produced sources -- are high enough in Northern California and Nevada that they leave little room for local ozone production under proposed stricter U.S. ground-level ozone standards, finds a new NASA-led study.
Can portabella mushrooms stop cell phone batteries from degrading over time?
Researchers at the University of California, Riverside Bourns College of Engineering think so.
EPA today confirmed that New Englanders experienced a slight increase in the number of unhealthy air quality days this year, compared to 2014 and 2013.
Based on preliminary data collected between April and September 2015, there were 24 days when ozone monitors in New England recorded concentrations above levels considered healthy. By contrast, in 2014 there were a total of 9 unhealthy ozone days, and in 2013 there were a total of 20 such days.
The number of unhealthy ozone days in each state this summer is as follows:
- 22 days in Connecticut (compared to 8 in 2014, and 18 in 2013)
- 4 days in Rhode Island (0 in 2014, and 7 in 2013)
- 3 days in Massachusetts (0 in 2014, and 6 in 2013)
- 2 days in Maine (0 in 2014, and 5 in 2013)
- 2 days in New Hampshire (1 in 2014, and 3 in 2013)
- 0 days in Vermont (0 in both 2014, and 2013).
New findings from NASA's Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present-day Mars.
Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious streaks are seen on the Red Planet.
Continued unsustainable harvesting of large predatory fish, including the culling of sharks, can have far-reaching consequences for the way we tackle climate change.
Los parques eólicos marinos que van a ser construidos en aguas de todo el Reino Unido podrían suponer una amenaza mayor de lo que se pensaba para las poblaciones protegidas de alcatraces, según una investigación dirigido por la Universidad de Leeds.
Antes se pensaba que los alcatraces, que se reproducen en el Reino Unido entre abril y septiembre de cada año, por lo general volaban muy por debajo de la altura mínima de 22 metros sobre el nivel del mar barridas por las aspas de las turbinas eólicas en el mar.
