Good Morning,
With contributions from scientists from several insti-
tutions, the U.K. science community has compiled the most
'comprehensive' phenology (long-term seasonal changes)
study to date. Check out all the details in the third

Scientists measure viral energy
PITTSBURGH - A U.S. physicist says he has, for the first
time, directly measured the energy associated with the ex-
pulsion of viral DNA into a cell. Carnegie Mellon Uni-
versity Associate Professor Alex Evilevitch said his team's
accomplishment could lead to fully understanding viral
infections, resulting in new drugs to interfere with the
process. "We are studying the physics of viruses, not the
biology of viruses," said Evilevitch. "By treating viruses
as physical objects, we can identify physical properties
and mechanisms of infection that are common to a variety of
viruses, regardless of their biological makeup, which could
lead to the development of broad spectrum antiviral drugs."
Evilevitch said his current findings also have the potential
to improve the development of gene therapy, which uses
viruses to deliver functional genes directly to human cells
to replace defective genes that are causing disease.
Evilevitch and his colleagues from Lund University in Sweden
and the University of Lyon in France said they used an
experimental technique to directly measure the heat, and
thus the thermal energy, released during viral genome
ejection. Until now, only indirect measurements of this
energy have been available. They describe their new method
in the Feb. 5 issue of the Journal of Molecular Biology.

Scientists say evolution shapes ecology
TALLAHASSEE, Fla. - U.S. scientists say an experiment with
two populations of guppies shows that evolution's influence
on ecology can be as great as the converse. Professors Joseph
Travis of Florida State University and David Reznick of the
University of California-Riverside said they studied guppies
who evolved to live in upstream communities of Trinidad, and
genetically distinct guppies who evolved to live downstream.
The researchers said that because upstream guppies have fewer
predators, they grow slowly and larger, reproduce later and
less, and die older. In contrast, downstream guppies live
where predators thrive, so that downstream guppies grow
rapidly and smaller, reproduce quickly and die younger. In
the experiment, the team introduced downstream guppies to
upstream habitats of artificial streams that were designed
to duplicate Trinidad's natural habitats The team found the
guppies made rapid and dramatic differences in the nutrient
cycles and overall productivity of the stream ecosystems.
Travis said the results show evolutionary change can drive
changes in the ecosystem, just as ecological change can
drive evolutionary changes in organisms. "Evolution can be
very fast," Travis said. "If you take downstream guppies
and introduce them to pools upstream with no guppies, the
descendants of those founders will evolve to look like up-
stream guppies in a few dozen generations." The study appears
in the online edition of the Proceedings of the National
Academy of Sciences.
Study assesses effects of earlier springs
WALLINGFORD, England - U.K. scientists studying global
change say they've found the trend toward earlier springs
and summers has affected a wide range of plants and animals.
The collaborative study, involving scientists from 12 U.K.
research institutions, universities and conservation organ-
izations, is said to be the most comprehensive assessment so
far of long-term changes in the seasonal timing (phenology)
of biological events across the United Kingdom's marine,
freshwater and terrestrial environments. Led by Stephen
Thackeray and Professor Sarah Wanless of the Center for
Ecology & Hydrology, the researchers said they analyzed more
than 25,000 long-term phenology trends for 726 species of
plants and animals. The study, among other things, found
more than 80 percent of trends between 1976 and 2005 indi-
cate earlier seasonal events. On average, the seasonal timing
of reproduction and population growth has become earlier by
more than 11 days over the whole period, but the scientists
said that change has accelerated during recent decades. "It
is important to realize that this analysis doesn't identify
which predator-prey relationships are most at risk of dis-
ruption due to changes in timing," said Wanless. "What it
does do is highlight that the recorded changes need urgent
investigation, particularly for species with high economic
or conservation importance." The study's findings are de-
tailed in the journal Global Change Biology.

Mars Express begins Phobos flybys
PARIS - The European Space Agency says its Mars Express
spacecraft started a series of flybys of Phobos Tuesday,
researching the origin of the mysterious Mars moon. The ESA
said the study will include a March 3 record low pass, with
the spacecraft passing just 31 miles above the moon's sur-
face. The latest Phobos flyby research started Tuesday at
12:52 a.m. EST, when Mars Express drew to within 616 miles
of Phobos' airless surface, ESA scientists said, noting the
flybys will continue at varying altitudes until March 26 when
Phobos moves out of range. "Because Mars Express is in an
elliptical and polar orbit with a maximum distance from Mars
of about 10,000 kilometers (6,200 miles), we regularly pass
Phobos," said Olivier Witasse, the ESA's Mars Express project
scientist. "Heavy emphasis is being placed upon the closest
flyby because it is an unprecedented opportunity to map
Phobos' gravity field," the space agency said. "This will
allow scientists to infer the moon's internal structure."
