Organic is only one ingredient in recipe for sustainable food future

Many people choose organic thinking it’s better for humans and the planet, but a new study finds that might not always be the case.
Carbon-based approaches for saving rainforests should include biodiversity studies
Posted: 10 Mar 2017 10:26 AM PST
Conservationists working to safeguard tropical forests often assume that old growth forests containing great stores of carbon also hold high biodiversity, but a new study finds that the relationship may not be as strong as once thought, according to a group of researchers.
NASA’s aerial survey of polar ice expands its Arctic reach
Posted: 10 Mar 2017 09:17 AM PST
For the past eight years, Operation IceBridge, a NASA mission that conducts aerial surveys of polar ice, has produced unprecedented three-dimensional views of Arctic and Antarctic ice sheets, providing scientists with valuable data on how polar ice is changing in a warming world. Now, for the first time, the campaign will expand its reach to explore the Arctic’s Eurasian Basin through two research flights based out of Svalbard, a Norwegian archipelago in the northern Atlantic Ocean.
Energy crop production on conservation lands may not boost greenhouse gases

Growing sustainable energy crops without increasing greenhouse gas emissions, may be possible on seasonally wet, environmentally sensitive landscapes, according to researchers.
Floods and hurricanes predicted with social media
Posted: 10 Mar 2017 06:19 AM PST
Social media can warn us about hurricanes, storms and floods before they happen, according to new research. Key words and photos on social media can signal developing risks – like water levels rising before a flood, say investigators. Found certain words – such as river, water and landscape – take on distinct meaning of forecast and warning during time periods leading to extreme weather events. Words can be used as ‘social sensors’, to create accurate early warning system for extreme weather, alongside physical sensors, the researchers conclude.
Measurements by school pupils paved way for key research findings on lakes and global warming
Posted: 10 Mar 2017 06:15 AM PST
With their measurements and samples, nearly 3,500 schoolchildren have assisted a research study on lakes and global warming. The results show that water temperatures generally remain low despite the air becoming warmer. This helps to curb the emission of greenhouse gases.
The new theory of economic ‘agrowth’ contributes to the viability of climate policies
Posted: 10 Mar 2017 06:19 AM PST
A new economic theory compatible with the fight against climate change has been proposed by a new study. The “agrowth” proposal comes up as an alternative to the opposing economic trends of “green growth” and “degrowth”

In order to maintain the microflora in the gut, the immune system must be taught to tolerate foreign bacteria. Researches have now shown how immune surveillance cells are educated to perform this task.
Soils could release much more carbon than expected as climate warms

Soils could release much more carbon dioxide than expected into the atmosphere as the climate warms, according to new research. Their findings are based on a field experiment that, for the first time, explored what happens to organic carbon trapped in soil when all soil layers are warmed, which in this case extend to a depth of 100 centimeters.
Petrol, jet fuel alternatives are produced by yeast cell factories

There have been many attempts to modify this stubborn little enzyme, but none have succeeded. Until now. New findings show that the fatty acid synthase (FAS) enzyme has started to produce sustainable chemicals for biofuels.
Can tree rings predict volcanic eruptions?

Scientists made a surprising discovery on their mission to find better indicators for impending volcanic eruptions: it looks like tree rings may be able to predict eruptions, report researchers.
