Moderate alcohol consumption in middle age can lower cardiac risk 
Previous studies have pointed out the benefits of moderate alcohol consumption as a factor in lowering cardiovascular risk. In a recent study researchers found that middle-aged non-drinkers who began consuming moderate amounts of alcohol saw an immediate benefit of lower cardiac disease morbidity with no change in mortality after four years.

Killer freeze of '07 illustrates paradoxes of warming climate
A destructive spring freeze that chilled the eastern United States almost a year ago illustrates the threat a warming climate poses to plants and crops, according to a paper just published in the journal BioScience. The study was led by a team from the Department of Energy's Oak Ridge National Laboratory.

Can moths or butterflies remember what they learned as caterpillars?
Butterflies and moths are well known for their striking metamorphosis from crawling caterpillars to winged adults. In light of this radical change, not just in body form, but also in lifestyle, diet and dependence on particular sensory cues, it would seem unlikely that learned associations or memories formed at the larval or caterpillar stage could be accessible to the adult moth or butterfly.

Warming climate may cause arctic tundra to burn
Research from ancient sediment cores indicates that a warming climate could make the world’s arctic tundra far more susceptible to fires than previously thought.

Invading trees put rainforests at risk
To the list of threats to tropical rainforests you can add a new one — trees. It might seem that for a rainforest the more trees the merrier, but a new study by scientists at the Carnegie Institution warns that non-native trees invading a rainforest can change its basic ecological structure — rendering it less hospitable to the myriad plant and animal species that depend on its resources.

Skeptics on Human Climate Impact Seize on Cold Spell
Extraordinary winter conditions in many parts of the world have been seized on by those who challenge warnings about dangerous human-caused global warming.

The Key to Safe and Effective Carbon Sequestration
Injecting our excess carbon dioxide into the rock under our feet may be the only way to stop a climate disaster. Geologist Bruce Yardley says that when CO2 is injected into minerals like feldspar, it will quickly react with the rock to create a clay "stopper" that could keep the gas there indefinitely.

Student Develops New LED, Wins $30,000 Lemelson-Rensselaer Prize
In recent years, light emitting diodes (LEDs) have begun to change the way we see the world. Now, a Rensselaer Polytechnic Institute student has developed a new type of LED that could allow for their widespread use as light sources for liquid crystal displays (LCDs) on everything from televisions and computers to cell phones and cameras.

Geoengineering: Does Dumping Iron in the Ocean Sequester CO2?
If we made made the globe warm, we can make the globe cool. That's the premise and promise of geoengineering, the name given to intentional attempts to alter the climate. But, the science behind most of the current schemes is relatively unproven.

Stabilizing climate requires near-zero carbon emissions
Now that scientists have reached a consensus that carbon dioxide emissions from human activities are the major cause of global warming, the next question is: How can we stop it" Can we just cut back on carbon, or do we need to go cold turkey" According to a new study by scientists at the Carnegie Institution, halfway measures won’t do the job.

Greenhouse effect has 'significantly dried' the western United States

Morphine dependency blocked by single genetic change
Morphine’s serious side effect as a pain killer – its potential to create dependency – has been almost completely eliminated in research with mice by genetically modifying a single trait on the surface of neurons. The study scientists think a drug can be developed to similarly block dependency.

At the end of March 2007, scientists all over the world observed with surprise and awe a rare change in the atmosphere of Jupiter. A giant perturbation occurred amongst its clouds and two extremely bright storms erupted in the middle latitudes of the northern hemisphere, where its most intense jet stream - reaching speeds of 600 kilometers per hour – resides.
