Methane and water vapour seem to be seeping out from below the surface.
In the first published study to track methane on Mars, researchers have
concluded that life is the only plausible source of the gas. The putative
martians are hiding in a few isolated spots and the rest of the planet is
totally sterile, they say.(...)
He and his colleagues used the Canada-France-Hawaii Telescope (...) to detect
minute traces of methane in the red planet's atmosphere; they found levels of
10 parts per billion. This matches other researchers' estimates, and suggests
that methane is being continually released from the surface.

You might think that the polar deserts are barren, lifeless places. But you
would be wrong. A British microbiologist has shown how the freezing and thawing
of ice can turn polar rocks into a haven for microorganisms.
What is more, he believes that meteor impacts, rather than being purely
destructive, could also create oases for life by heating rocks and melting ice,
either on Earth or on other icy worlds in the Solar System.(...)

Excerpts: (...) After the formation of our planet and its atmosphere, prebiotic
chemical evolution started its course with the formation of the first building
blocks for the formation of biomolecules. In the case of proteins, those
building blocks were amino acids that had to be formed in the primitive
atmosphere, and then had to react to peptides and proteins as the main pillar
of first life. In this paper, we describe the processes in the primordial

Wings made little difference for speciation. About one-third of both winged and
flightless insects had become new species when their range was sliced up by a
geographical barrier--in this case, a dry valley. In addition, the absence of
wings did not appear to hamper dispersal, (...). Apparently, says Brooks,
"flightless insects have other means of dispersal than flying, and flying
insects do not fly as far as they might." He adds that insects may fly more for

Adapt or die. This axiom has been used so many times, in so many different
contexts, that its origin is difficult to trace. But it aptly describes an
intriguing mechanism exploited by viruses that infect Bordetella bacteria. This

would otherwise severely limit their ability to infect and multiply.

Researchers probing our past have often studied two kinds of DNA: the
paternally inherited Y chromosome and the maternally inherited mitochondrial
DNA (mtDNA). When comparing people in far-flung regions, they found that mtDNA
was more similar than were the Y chromosomes. This evidence of more homogenized
mtDNA suggested that throughout human history, women have spread their genes

Scientists have for the first time genetically modified plants to contain a

A special sequence of DNA was inserted
Current methods of switching genes on and off usually involve complicated
systems and have serious side effects like cancer. (...) The new method
involves inserting a special DNA sequence into the patient's own genes or into
the therapeutic gene introduced by gene therapy. (...) This piece of DNA holds
coding for making something called ribozyme. Ribozyme contains the instructions
for switching genes on, but has a natural tendency to split itself in half
meaning the instructions cannot be read and the genes remain switched off.
Drugs can stop ribozyme splitting so the "therapeutic" genes are switched on.

researchers confirm that a key anti-cell-death molecule called BCL-2 is

of California, San Diego (UCSD) School of Medicine.
The findings provide new insight into the immune system's response to

delicate balance between cancer promotion and inhibition can be manipulated in

Excerpt: Moreover, most solid tumours contain many non-malignant cells,
including immune cells and blood-vessel cells, that are important in
inflammation. But the crucial molecular pathways that permit communication
between abnormally growing cancer cells and these inflammatory cells remain
unknown. A complex network of pro-inflammatory mediators is probably involved,
because deletion of certain key molecules can reduce cancer susceptibility in
mice. Two mouse models of inflammation-associated cancer now implicate the
gene-transcription factor NF-B and the inflammatory mediator known as
tumour-necrosis factor- (TNF-) in cancer progression.

09. Theory Predicts The Uneven Distribution Of Genetic Diversity Within Species
Excerpt: Global efforts to conserve species have been strongly influenced by
the heterogeneous distribution of species diversity across the Earth. This is
manifest in conservation efforts focused on diversity hotspots. The
conservation of genetic diversity within an individual species is an important
factor in its survival in the face of environmental changes and disease. (...)
Contrary to previous studies, our results imply that diversity loss due to
severe extinction events is high and focusing conservation efforts on highly
distinctive groups can save much of the diversity.

09.01. Invasion In Space And Time: Non-Native Species Richness And Relative
Abundance , Ecol. Lett.
Excerpts: Ecologists have long sought to understand the relationships among
species diversity, community productivity and invasion by non-native species.
Here, four long-term observational datasets were analyzed using repeated
measures statistics to determine how plant species richness and community
resource capture (i.e. productivity) influenced invasion. Multiple factors
influenced the results, including the metric used to quantify invasion,
interannual variation and spatial scale. (...) Our analysis suggests that while
non-natives were most likely to establish in species rich communities, their
success was diminished by high resource capture by the resident community.

Excerpts: This paper examines the nature of uncertainty in integrated
econometric+input-output (ECIO) regional models. We focus on three sources of
uncertainty: (a) econometric model parameter uncertainty; (b) econometric
disturbance term uncertainty; and (c) input-output coefficient uncertainty.
Through a series of Monte Carlo simulations we analyse the relative importance
of each component as well as the question of how their interaction may
propagate through the integrated model to affect the distributions of the
endogenous variables. Our results suggest that there is no simple answer to the
question of which source of uncertainty is most important in an integrated

10.01. How to Compute Using Globally Coupled Oscillators , arXiv
Abstract: Synchronization is known to play a vital role within many highly
connected neural systems such as the olfactory systems of fish and insects. In
this paper we show how one can robustly and effectively perform practical
computations using small perturbations to a very simple globally coupled
network of coupled oscillators. Computations are performed by exploiting the
spatio-temporal dynamics of a robust attracting heteroclinic network (also
referred to as `winnerless competition' dynamics). We use different cluster
synchronization states to encode memory states and use this to design a simple
multi-base counter. The simulations indicate that this gives a robust
computational system exploiting the natural dynamics of the system.

Abstract: In this article, we show how psychological theories of emotion shed
light on the interaction between emotion and cognition, and thus can inform the
design of human-like autonomous agents that must convey these core aspects of
human behavior. We lay out a general computational framework of appraisal and
coping as a central organizing principle for such systems. We then discuss a
detailed domain-independent model based on this framework, illustrating how it
has been applied to the problem of generating behavior for a significant social
training application. The model is useful not only for deriving emotional
state, but also for informing a number of the behaviors that must be modeled by
virtual humans such as facial expressions, dialogue management, planning,
reacting, and social understanding. Thus, the work is of potential interest to
models of strategic decision-making, action selection, facial animation, and

12. A Taylor Vortex Analogy In Granular Flows , Nature
Excerpt: Here, using gas fluidization to overcome jamming, we show
experimentally that granular materials develop vortices consistent with the
primary Taylor instability in fluids. However, the vortices observed in our
fluidized granular bed are unlike those in fluids in that they are accompanied
by novel mixing-segregation transitions. The vortices seem to alleviate
increased strain by spawning new vortices, directly modifying the scale of
kinetic interactions. Our observations provide insights into the mechanisms of
shear transmission by particles and their consequent convective mixing.
