The professor worries that rising CO2 levels could drive enough warming to destabilize the Earth's clathrate reserves.

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.

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
In contrast, aromatic-DNA adducts and HPRT were not correlated in either year.
2
The main endpoint was the analysis of hepatic and intestinal DNA adducts.
3
After smoking interindividually variable additional adducts were visible in active smokers only.
4
The p53 genetic polymorphism revealed a significantly positive effect on DNA adducts formation.
5
These findings provide a basis for understanding the replication of related O6-dG adducts.
6
MALDI-IM-TOFMS was also used to resolve DNA-platinum adducts from the corresponding unmodified oligonucleotides.
7
The DNA adducts can be used as biomarkers for studies of AA toxicity.
8
In the present study, the formation of protein adducts was investigated.
9
Protein carbonylation and 4-hydroxynonenal protein adducts were measured as markers of oxidative damage.
10
The levels of THF-dG in DNA exceeded that of other adducts of alpha-acetoxyNPYR.
11
Etheno adducts in DNA arise from multiple endogenous and exogenous sources.
12
NM-adducts block DNA replication in cancer cells by forming cytotoxic DNA interstrand cross-links.
13
Therefore, such adducts often result in mutations upon DNA replication.
14
Additionally, we report significant detection of DMPO-CPB1 adducts in mice experiencing normal physiological conditions.
15
It is now possible to quantitate carcinogen adducts on DNA by highly sensitive immunoassays.
16
The particulate material contained approximately the same number of adducts as the modified RNA.
