LOS ANGELES (Reuters) - 23andMe, a Google-funded online company selling a $999 DNA test, launched on Monday as a kind of genetics-based MySpace or Facebook that also has the more serious aim of allowing medicine someday to target Americans' ills more precisely.
Delay in Autumn Colour is Caused by Increased Atmospheric CO2 not Global Warming
November 19, 2007 08:44 AM - University of Southampton
The delay in autumnal leaf coloration and leaf fall in trees is caused by rising levels of carbon dioxide (CO2) in the atmosphere and not by increased global temperatures, suggests a new study by researchers at the University of Southampton.
In recent years, woodland autumnal colour changes have been occurring later in the season whilst re-greening in spring has been occurring earlier. During the last 30 years across Europe, autumnal senescence – the process of plant aging where leaves discolour and then fall – has been delayed by 1.3 - 1.8 days a decade. To date, this has been explained by global warming, with increasing temperatures causing longer growing seasons.
Local sources major cause of US near-ground aerosol pollution
November 18, 2007 09:16 AM - NASA/Goddard Space Flight Center
A new NASA study estimates that most ground-level particulate pollution in the United States stems from regional sources in North America and only a small amount is brought to the country from other parts of the world.
Researchers using an innovative global aerosol tracking model have for the first time produced a global estimate of sources and movements of aerosols near the ground where they can affect human health and run afoul of environmental regulations. Previously, researchers studying aerosols moving between continents focused primarily on tracking a single type of aerosol, such as dust or black carbon, or measuring their quantities throughout the atmosphere. This left gaps in understanding where ground-level particulate pollution comes from.

Roman road, bath unearthed near Jewish temple site
November 16, 2007 08:47 AM - Rebecca Harrison -Reuters
JERUSALEM (Reuters) - Israeli archaeologists have unearthed the remains of a second century terraced street and bath house which provide vital clues about the layout of Roman Jerusalem.
The Israel Antiquities Authority said the 30-metre (90-foot) alley was used by the Romans to link the central Cardo thoroughfare with a bath house and with a bridge to the Temple Mount, once the site of Jerusalem's ancient Jewish temple.
Weird dinosaur was "cow of the Mesozoic"
November 16, 2007 08:40 AM - Reuters
WASHINGTON (Reuters) - A strange-looking dinosaur with rows of tiny teeth crammed into the very front of its jaws and fragile air-filled bones may have been the "cow of the Mesozoic," and far more common than better-known dinosaurs, scientists said on Thursday.
Its shovel-shaped jaws and tightly packed teeth -- up to 10 rows of teeth -- allowed Nigersaurus taqueti to vacuum through ferns and other ground cover, a team led by Paul Sereno at the University of Chicago reported.
Comet Holmes' display captivates stargazers
November 16, 2007 08:38 AM - Julie Steenhuysen -Reuters
The normally sedate Comet Holmes made a bright splash in the sky about two weeks ago, unexpectedly becoming a million times brighter than normal overnight and causing a stir among astronomers.
The comet and its expanding ball of dust have become the biggest object in the solar system, with a diameter appearing even bigger than the sun, according to astronomers at the University of Hawaii Institute for Astronomy.

New south Florida nursery to focus on staghorn corals
November 15, 2007 09:46 AM - University of Miami Rosenstiel School of Marine & Atmospheric Science
In response to the need for localized efforts to protect and recover the surviving populations of the threatened staghorn coral, Diego Lirman, Ph.D., and James Herlan, researchers from the University of Miami’s Rosenstiel School of Marine and Atmospheric Science (RSMAS) have established an underwater nursery dedicated to the propagation of staghorn corals.
Yellowstone Viruses 'Jump' Between Hot Pools
November 15, 2007 09:36 AM - INL
A population study of microbes in Yellowstone National Park hot pools suggests viruses might be buoyed by steam to distant pools. The result, to be published online next week in the Proceedings of the National Academy of Sciences, could help to answer some fundamental questions about how microbes, and the viruses that infect them, impact their environment.
