Scientists may have just made the breakthrough of a lifetime, turning discarded fruit peels and other throwaways into cheap, clean fuel to power the world's vehicles. Univ. of Central Florida professor Henry Daniell has developed a way to produce ethanol from waste products such as orange peels and newspapers.

UCLA chemists report creating a synthetic "gene" that could capture heat-trapping carbon dioxide emissions, which contribute to global warming, rising sea levels, and the increased acidity of oceans.

Even as countries like the U.S.
and China spar in Copenhagen, some
agreements have already been struck, including one to fund reduced emissions
from deforestation. But as researchers have recently pointed out, unless
safeguards are in place the funding could merely transfer carbon emissions to
another source rather than eliminate them.

The main elements of a global pact on climate change is in place, but in the areas of financing and greenhouse gas emissions cuts there remain open holes that world leads hope to fill in next week. The six-page document was distilled from 180 pages.

The full Senate has yet to take up climate change legislation that cleared its environment committee, but at the climate conference in Copenhagen the EPA Administrator Lisa Jackson offered Pres. Obama another avenue: by acknowledging that carbon emissions threaten the health of Americans, the EPA can regulate these gases under the Clean Air Act without the approval Congress.

Lawrence Livermore National Laboratory has received $3
million in American Recovery and Reinvestment Act dollars to capture and
transport 1 million tons of carbon dioxide from Bay Area power plants and
inject it more than two miles underground. The gas will be captured at its
source and funneled via pipeline to the Central Valley.

Researchers at the Univ. of Oklahoma Health Sciences Center are helping to lead a massive international study on the possible genetic effects of radiation and cancer drug exposures on future generations. The study’s principal investigators are meeting this week at the OU Health Sciences Center to discuss their recent findings.

A new mobile air research laboratory will help a team of researchers led by a Michigan State Univ. professor better understand the damaging health effects of air pollution and why certain airborne particles—emitted from plants and vehicles—induce disease and illness.

Researchers at MIT have shown the benefits of a new approach toward eliminating carbon-dioxide (CO2) emissions at coal-burning power plants. Their system, called pressurized oxy-fuel combustion, provides a way of separating all of the carbon-dioxide emissions produced by the burning of coal, in the form of a concentrated, pressurized liquid stream. This allows for carbon dioxide sequestration: the liquid CO2 stream can be injected into geological formations deep enough to prevent their escape into the atmosphere.

Nitrous oxide has now become the largest ozone-depleting
substance emitted through human activities, and is expected to remain the
largest throughout the 21st century, NOAA scientists say in a new study. For
the first time, this study has evaluated nitrous oxide emissions from human
activities in terms of their potential impact on Earth’s ozone layer.
