Fossils Suggest An Ancient CO2-Climate Link

Mark Pink / Alamy

From Time Magazine:

Some of the best evidence linking rising carbon dioxide levels to a warmer world comes from the coldest places on earth. Samples of ancient air extracted from deep inside the Antarctic and Greenland ice caps make it clear that CO2 is scarce in the atmosphere during ice ages and relatively abundant during warmer interglacial periods — like the one we're in now.

The relationship between CO2 and climate is clear going back about 800,000 years. Before that, however, it gets murkier. That's largely because ice and air that old haven't yet been found. So scientists rely instead on indirect measurements — and these have led to a climate mystery: some episodes of past warming, including a planetary heat wave about 15 million years ago and another about 3.5 million years ago, seem to have happened without a rise in CO2. No one quite understands why. Maybe other greenhouse gases were the cause — methane, for example. Or maybe it had to do with changes in ocean circulation.

Europa, Jupiter's Moon, Could Support Complex Life

Europa, pictured above, may have enough oxygen to support complex, animal-like organisms, according to a new study. NASA

From Discovery:

Jupiter's moon Europa should have enough oxygen-rich water to support not only simple micro-organisms but also complex life, according to a University of Arizona researcher who studies ice flows on the frozen moon.

Judging by how quickly Europa's surface ice is replenished, Richard Greenberg estimates that enough oxygen reaches the subterranean ocean to sustain "macrofauna" -- more complex, animal-like organisms.

Why NASA Barred Women Astronauts

From New Scientist:

About 50 years ago, as the US worked towards putting its first men in space, a few people thought there was another option: women in space. The facts about this episode have been somewhat obscured by the myths that have grown up around it.

In 1960-61, a small group of female pilots went through many of the same medical tests as the Mercury astronauts, and scored very well on them – in fact, better than some of the astronauts did. A new study that presents the first published results of their physiological tests shows that much is fact.

Acidic Clouds Nourish World's Oceans

Water droplets in clouds generally form around dust and other particles. When clouds evaporate, as they often do naturally, the surface of the particle can become very acidic. This is especially true where the air is polluted. Paradoxically, scientists suggest that large scale industry in countries like China could be combating global warming to some extent by creating more bioavailable iron in the oceans, and therefore increasing carbon dioxide removal from the atmosphere. (Credit: Copyright Michele Hogan)

From Science Daily:

Science Daily (Oct. 6, 2009) — Scientists at the University of Leeds have proved that acid in the atmosphere breaks down large particles of iron found in dust into small and extremely soluble iron nanoparticles, which are more readily used by plankton.

This is an important finding because lack of iron can be a limiting factor for plankton growth in the ocean - especially in the southern oceans and parts of the eastern Pacific. Addition of such iron nanoparticles would trigger increased absorption of carbon dioxide from the atmosphere.

Ancient Rome's Real Population Revealed

From Live Science:

The first century B.C. was one of the most culturally rich in the history of the Roman Empire — the age of Cicero, Caesar and Virgil. But as much as historians know about the great figures of this period of Ancient Rome, they know very little about some basic facts, such as the population size of the late Roman Empire.

Now, a group of historians has used caches of buried coins to provide an answer to this question.

During the Republican period of Rome (about the fifth to the first centuries B.C), adult male citizens of Rome could be taxed and conscribed into the army and were also given the right to vote. To keep track of this section of the population (and their taxable assets), the Roman state conducted periodic censuses.

The ecological risks and health effects of a bright night are becoming more apparent.

The night is not what it was. Once, the Earth was cast perpetually half in shadow. Man and beast slept beneath inky skies, dotted with glittering stars.

Why Nondrinkers May Be More Depressed

Ruediger Knobloch / A.B. / Corbis

From Time Magazine:

Alcohol has a peculiar relationship to happiness. We drink to celebrate, but because alcohol works as a depressant, it ends up deadening feelings. Not surprisingly, there's an observable correlation between alcoholism and depression, and even though it's not always clear which leads to which, everyone knows you can't drink like a Sterling Cooper employee for too long before becoming a perpetual sad sack.

But if alcohol can lead to depression, does that mean abstaining from alcohol will make you happier? A new study suggests that the opposite actually tends to be true. In fact, those who never drink are at significantly higher risk for not only depression but also anxiety disorders, compared with those who consume alcohol regularly.

Bees Fight Back Against Colony Collapse Disorder: Some Honey Bees Toss Out Varroa Mites

ARS researchers have developed honey bees that more aggressively deal with varroa mites, a parasite that is one of the major problems damaging honey bees today. (Credit: Photo by Stephen Ausmus)

From Science Daily:

Science Daily (Oct. 5, 2009) — Honey bees are now fighting back aggressively against Varroa mites, thanks to Agricultural Research Service (ARS) efforts to develop bees with a genetic trait that allows them to more easily find the mites and toss them out of the broodnest.

The parasitic Varroa mite attacks the honey bee, Apis mellifera L., by feeding on its hemolymph, which is the combination of blood and fluid inside a bee. Colonies can be weakened or killed, depending on the severity of the infestation. Most colonies eventually die from varroa infestation if left untreated.
