The professor worries that rising CO2 levels could drive enough warming to destabilize the Earth's clathrate reserves.
2
In our world now, clathrates exist in Arctic permafrost and in the ocean near the continents.
3
Another source could be icy subsurface clathrates, or molecular cages that harbour methane but can release it in bursts over time.
4
The presence of clathrates, ice-like lattice structures that can trap gases, could just as easily explain what we see on the moon.
5
Dubbed SCHLIP, for Submarine Clathrate Hydrate Landslide Imaging Project, the investigations continue and will involve drilling into the landslide during the next voyage.

This technique has the advantage that the biologically inactive cagedcompound can be applied at equilibrium prior to the near instantaneous release of the transmitters.
1
Cations are favoured as guests over isoelectronic neutral species, as the resulting host-guestcomplexes experience additional stability due to cooperative effects.
2
Clip C1 forms highly stable host-guestcomplexes with the flavylium salts 1 and 2 and the quinoidal base 3A in methanol.

1
However, no such background adduct was detected in skin DNA of mice.
2
An indole-dioxygen adduct has been built which fits the electron density convincingly.
3
However, the production of this adduct in vivo has been difficult to prove.
4
The major charge inversion reaction channels include multiple proton transfer and adduct formation.
5
This adduct causes the radioiodine to become trapped in lysosomes following antibody catabolism.
6
Watson-Crick hydrogen bonding is intact at and beyond the adduct site.
7
TCDD pretreatment altered the adduct distribution in lung but not in liver slices.
8
If true, then it becomes imperative to explore different reasonable conformations for this adduct.
9
The method can be applied to compare AA-DNA adduct formation in cells and tissues.
10
A crystal structure of OAT and FCP showed the formation of a ternary adduct.
11
It can be difficult to determine both the nature and number of adduct species present.
12
This is very different from the adduct alignments hitherto observed in free or protein-bound DNA.
13
On the contrary, oral treatment with 1-MIM-OH produced the highest adduct levels in the liver.
14
Other products that may have included the isomeric trans-N2-dGuo adduct were formed in the reaction.
15
Reactions with nucleic acids such as adduct formation and strand breaks are discussed among others.
16
This report includes the first detailed description of a dC adduct of an aromatic amine.
