Indoor HEPA filters significantly reduce pollution indoors when outside air unhealthy, study finds
Tue, 25 Sep 2018 11:00:30 EDT
Outdoor air pollution is a major contributor to indoor air pollution -- but high-efficiency particulate air (HEPA) filters used in the home significantly reduce fine-particulate matter in the air compared with non-HEPA air filters, according to a new study.
'Ground coffee' with soil perks in Brazil
Mon, 24 Sep 2018 16:21:46 EDT
Coffee harvesting is often done with heavy machinery that can compact the soil. Additionally, up to 20 percent of coffee berries fall to the ground. Researchers brewed up a solution to restore soil and decrease the loss.
Sex in plants requires thrust
Mon, 24 Sep 2018 16:09:30 EDT
In plants, to fertilize the egg, the pollen tube (which is between 1/20 and 1/5 of the width of a human hair) has to navigate through a maze of tissue, no matter what obstacles it encounters. Thanks to the lab-on-a chip technology scientists were able to actually see and measure exactly what was going on within the pollen tube as it grew.
How will climate change stress the power grid? Hint: Look at dew point temperatures
Mon, 24 Sep 2018 14:40:28 EDT
A new study suggests the power industry is underestimating how climate change could affect the long-term demand for electricity in the United States. The research describes the limitations of prediction models used by electricity providers and regulators for medium- and long-term energy forecasting. It outlines a new model that includes key climate predictors that researchers say present a more accurate view of how climate change will alter future electricity demands.
Research forecasts US among top nations to suffer economic damage from climate change
Mon, 24 Sep 2018 11:28:02 EDT
For the first time, researchers have developed a data set quantifying what the social cost of carbon -- the measure of the economic harm from carbon dioxide emissions -- will be for the globe's nearly 200 countries. Although much previous research has focused on how rich countries benefit from the fossil fuel economy, while damages accrue primarily to the developing world, the top three counties with the most to lose from climate change are the United States, India and Saudi Arabia -- three major world powers.
Ready-to-use recipe for turning plant waste into gasoline
Mon, 24 Sep 2018 11:04:22 EDT
Bioscience engineers already knew how to make gasoline in the laboratory from plant waste such as sawdust. Now researchers have developed a roadmap, as it were, for industrial cellulose gasoline.
National parks bear the brunt of climate change
Mon, 24 Sep 2018 09:16:54 EDT
Human-caused climate change has exposed US national parks to conditions hotter and drier than the rest of the nation, says a new study quantifying for the first time the magnitude of climate change on all 417 parks in the system. Without action to limit greenhouse gas emissions, many small mammals and plants may be brought to the brink of extinction by the end of the century, the study shows.
New battery gobbles up carbon dioxide
Fri, 21 Sep 2018 14:01:46 EDT
New technology could use carbon dioxide captured from power plants to make a new kind of lithium battery.
Light pollution makes fish more courageous
Fri, 21 Sep 2018 11:34:56 EDT
Artificial light at night also makes guppies more courageous during the day, according to a new behavioral study.
Cooking with wood or coal is linked to increased risk of respiratory illness and death
Fri, 21 Sep 2018 09:24:47 EDT
Burning wood or coal to cook food is associated with increased risk of hospitalization or dying from respiratory diseases.
Extra Arctic observations can improve predictability of tropical cyclones
Fri, 21 Sep 2018 09:24:27 EDT
Scientists have found that additional weather observations in the Arctic can help predict the track and intensity of tropical and mid-latitude cyclones more accurately, improving weather forecasting of extreme weather events.
Land-based bird populations are at risk of local extinction
Thu, 20 Sep 2018 20:32:41 EDT
A new report finds that land-based bird populations are becoming confined to nature reserves in some parts of the world -- raising the risk of global extinction -- due to the loss of suitable habitat.
What's eating these endangered orchids?
Thu, 20 Sep 2018 16:10:33 EDT
A species of seed-feeding fly is critically damaging the seed production of multiple orchid species, as revealed by a group of Japanese researchers. If the damage caused by this fly is occurring long-term and across Japan, these already-endangered orchid species could become unable to reproduce using seeds, and their dwindling numbers will take a large hit.
NASA balloon mission captures electric blue clouds
Thu, 20 Sep 2018 16:08:45 EDT
Scientists share mesmerizing new images of electric blue clouds from NASA's PMC Turbo balloon mission that flew in over the Arctic in July 2018.
Glacial engineering could limit sea-level rise, if we get our emissions under control
Thu, 20 Sep 2018 10:21:38 EDT
Targeted engineering projects to hold off glacier melting could slow down ice-sheet collapse and limit sea-level rise, according to a new study. While an intervention similar in size to existing large civil engineering projects could only have a 30 percent chance of success, a larger project would have better odds of holding off ice-sheet collapse. But the researchers caution that reducing emissions still remains key to stopping climate change and its dramatic effects.
Hidden costs of cobalt mining in DR Congo
Thu, 20 Sep 2018 10:21:07 EDT
Cobalt mining comes at a great cost to public health in the Democratic Republic of the Congo. New research reveals that children are particularly vulnerable: their urine and blood samples contain high concentrations of cobalt and other metals.
Physicists train robotic gliders to soar like birds
Thu, 20 Sep 2018 10:16:05 EDT
Scientists know that upward currents of warm air assist birds in flight. To understand how birds find and navigate these thermal plumes, researchers used reinforcement learning to train gliders to autonomously navigate atmospheric thermals. The research highlights the role of vertical wind accelerations and roll-wise torques as viable biological cues for soaring birds. The findings also provide a navigational strategy that directly applies to the development of UAVs.
Climate change modifies the composition of reefs
Thu, 20 Sep 2018 10:11:10 EDT
Corals devastated by climate change are being replaced naturally by other species such as gorgonians, which are less efficient in acting as a carbon sink. A study has analyzes for the first time why gorgonians are more resistant than corals to human impacts and global climate change.
