Their discoveries described in a paper published online today in Cell include identification of a molecule that protects neurons from pesticide damage.
For the first time we have used human stem cells derived from Parkinson's disease patients to show that a genetic mutation combined with exposure to pesticides creates a'double hit'scenario producing free radicals in neurons that disable specific molecular pathways that cause nerve-cell death

One molecule we identified was protected isoxazole which mutant neurons from cell death induced by the tested pesticides.

The new method created by engineers in Rice's Multiscale Materials Modeling Lab accurately calculated the ability of two zeolites small cage-like molecules with enormous surface area to trap and store gas molecules.
but the molecules they can store that the lab looked at--hydrogen methane and nitrogen--are much smaller.
The zeolites'enormous surface area inside and out gives gas molecules plenty of room to bind.
Aside from storing hydrogen for fuel ZIFS show potential for size-selective catalysis environmental remediation and for use as molecular sieves.
Shahsavari said the researchers modeled the interactions between molecules of the three gases with each other and with the binding ligands in the zeolites at 77 and 300 kelvins(-321 and 80 degrees Fahrenheit respectively) and at various pressures.
but if we can functionalize the ZIFS by adding ligand-binding moieties (the functional groups in a molecule) into the pore space then we might be able to.
For example they came to the counterintuitive conclusion that ZIF-100 the larger of the two zeolites could adsorb more small-molecule hydrogen but fewer of the larger methane molecules than ZIF-95 under similar conditions.
First the team performed first-principle calculations to describe the very weak atomic interactions--the Van der waals-related London dispersion forces--among each of the three types of gas molecules and the two ZIFS.
but calculating integrative forces between thousands of gas molecules and each ZIF was not. It took the combined power of Rice's DAVINCI
Even so calculations for a single data point--one molecule one zeolite one temperature--often took 96 processing cores three days to complete.
It can work not only for single molecules but also gas mixtures he said. This provides a good computational framework so one can do rapid screening for the desired properties.

#Carbon storage recovers faster than plant biodiversity in regrowing tropical forestsa new study of regrowing tropical forests has concluded that plant biodiversity takes longer to recover than carbon storage following major disturbances such as clearance for farming.
and carbon pools in regrowing forests. Over half of all tropical forests have already been converted for agriculture logged
Regrowing forests could help both to soak up carbon emissions produced by human activities and to reduce species extinctions.
although carbon recovered most quickly even after 80 years regrowing forests tended to have less carbon than old-growth forests.
which hold more carbon to become established. In contrast although the number of tree species recovered relatively rapidly many species characteristic of old-growth forests were rare in regrowing forests.
The research team conducted a synthesis of data collected from more than 600 secondary forest sites from 74 previous studies describing carbon pools
#In the study the researchers point out that these results show that forests that are regrowing following agricultural use may be more valuable for the carbon they store than for their biodiversity for the first 100 years.
Policies such as Reducing Emission from Deforestation and Degradation (REDD) often assume that carbon and biodiversity are interchangeable.
While the re-growth of forests following clearance is valuable in soaking up carbon the biodiversity benefits will take a very long time to emerge.#
and suggest a possible mechanism underlying it one based on interspecies carbon exchange. Their results suggest that trees at drier sites buy insurance for their leaves in the form of beefed-up ant protection
and pay for it with carbon the coin of the realm. All plant-animal mutualisms may employ a similar insurance model according to Pringle a postdoctoral fellow in the Michigan Society of Fellows and an assistant professor in the Department of Ecology and Evolutionary Biology and at the School of Natural resources and Environment.
and then we realized that carbon exchange can explain it. To test whether water limitation strengthens the defensive mutualism between Ecuador laurel trees (Cordia alliodora)
through the scale insects the trees indirectly pay a carbon fee in the form of sugar-rich sap that is distilled into honeydew to the ants in exchange for guard duty.
and use it to convert carbon dioxide and water into carbon-based carbohydrates which are used for food by the trees the scale insects and the ants.
because laurels there have smaller carbon reserves and a shorter rainy season means they have less time to replace lost leaves.
Pringle and her colleagues used a mathematical model to test this idea looking at the relative costs and benefits of carbon trading between trees and ants under rainy seasons of varying durations.
Water limitation together with the risk of herbivory increases the strength of a carbon-based mutualism the researchers say.
animal and plant communities change ecosystem functions disappear carbon emissions contribute to climate change. Whatever happens regionally has global consequences.

The new research published in October in the journal Molecular Biosystems is part of a worldwide effort to create fuels from plants that are plentiful
Seventy years later T. reesei is a star in the world of biofuels because of its ability to churn out enzymes that chew through molecules like complex sugars.

It uses the molecules captured in the wood to sample the atmosphere of the past.
but a small percentage of oxygen is the heavier O-18 isotope. When seawater evaporates off the ocean to form clouds some drops fall as rain over the ocean
and more of the heavier O-18 molecules rain out. The remaining drops that fall on land thus have a higher proportion of the lighter O-16 molecules.
Fog on the other hand forms near shore and blows on land where it drips down through the branches until the trees use it like rainwater.
Researchers also analyzed carbon atoms to measure the total amount of moisture in the air. We actually have two indicators that we can use in combination to determine
In addition to exposures to individual chemicals and compounds the researchers looked at exposure to multiple chemicals
In other words a forest stores carbon from the atmosphere that would otherwise contribute to the greenhouse effect--and global warming.
But for all the carbon being stored in these trees aboveground a roughly equal amount of carbon is stored belowground.
Carbon on balancethis efficient decomposition is why home gardeners love earthworms: they break down organic matter releasing nutrients.
since in breaking down that organic matter they redistribute carbon throughout the soil changing the basic layering of forest floors
The worms also release carbon dioxide as they eat adding to the forest's carbon emissions.
and there is a big carbon loss and change in the forest floor says Don Ross holding up three different species on his hand.
As these earthworms move through the soil they're ingesting mineral particles along with organic particles glomming them together inside their digestive track.
And when they poop says Knowles they produce what we call an aggregate. Over time it seems these soil aggregates might physically protect the organic carbon inside them forming a barrier to the microorganisms that could
otherwise break it down. So the question is Gorres asks over the long run do earthworms create a negative balance or positive balance on carbon?
Part of this research project--sponsored by the Northeastern States Research Cooperative and exploring eighteen forest plots across Vermont--aims to answer that question.
if earthworms are increasing that physical protection of carbon. Land use historyrecent studies in the Northern Forest have shown that land use changes--like agricultural abandonment
or intensive tree harvesting--can dramatically change the amount of carbon stored in that land's soils.
Much of the Northern Forest that was tilled previously farmland is currently gaining stored carbon. But what was the soil carbon like before European settlement?
And how much does the current earthworm invasion threaten these gains? It's hard to say.
The eighteen plots the team is studying intensively have widely varying amounts of belowground carbon
and land use history influences the amount of carbon in the soil. Carbon creditsthis is a matter of more than scientific interest.
When we're trying to set up policies about how to increase sequestration of carbon from the air says Sandy Wilmot a forest scientist with the State of Vermont
and a partner on this project it would be very helpful to know how to manage the soil as well as the aboveground.
For example differing forestry techniques clearly affect aboveground carbon storage and are likely to also influence belowground carbon too.
They may also have an effect on the likelihood of earthworm invasion. Human-generated carbon
--and its capture--is starting to develop into big business. Around the world various types of carbon markets are emerging in the effort to slow
and regulate climate change. Credits in these markets generally depend on being able to show that carbon is being sequestered out of the atmosphere--and held long-term.
But belowground carbon is nearly impossible to include in these markets or other mitigation efforts because it's hard to measure.
Forest soil carbon is understood poorly and so it's often not counted or even removed from some forest carbon protocols says Cecilia Danks a social scientist at UVM.
I've been brought in to this earthworm project to try to figure out: is there a carbon market connection?
You don't get credit in the market right now--for the most part--for forest soil carbon. This research effort aims to move toward a better accounting of carbon in the Northern Forest and perhaps Danks hopes the chance for New england forestland owners to get a return on the carbon stored below their feet even carbon passing through the bowel
