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.

Myths About Diabetes And Diet Persist
From Live Science:Once upon a time, in the dark ages of the 1960s and '70s, a diabetes diet meant avoiding sugar. Refrigerators of diabetics were filled with Fresca; sugar bowls were filled with Sweet'N Low; and, for the most part, plates were still filled with meat and potatoes.
That diet didn't work so well, and self-administered insulin shots were often needed to keep blood-sugar levels safe.

LCROSS Impact Site Picked
From Discover Magazine:
NASA has chosen the final destination for the LCROSS lunar impacting probe: the crater Cabeus A, near the Moon’s south pole.
So why is NASA smacking a probe into the Moon at high speed, and why there?
The idea is that over millions and billions of years, a lot of comets have hit the Moon. The water from these comets hits the surface and sublimates away… but if any settles at the bottoms of deep craters near the Moon’s poles, these permanently shadowed regions can act as a refrigerator, keeping the water from disappearing. It can stay there, locked up as ice, for a long, long time. Some estimates indicate there could be billions of tons of ice near the Moon’s south pole.

Roman Coin Hoards Show More War Means Fewer Babies
From Wired Science:
Coins buried by anxious Italians in the first century B.C. can be used to track the ups and downs of the Roman population during periods of civil war and violence.
In times of instability in the ancient world, people stashed their cash and if they got killed or displaced, they didn’t come back for their Geld. Thus, large numbers of coin hoards are a good quantitative indicator of population decline, two researchers argue in in the Proceedings of the National Academy of Science Monday.

Baby Mammoth Yields Secrets After 40,000 Years In Siberian Tundra
From Times Online:
A baby woolly mammoth that died after being sucked into a muddy river bed 40,000 years ago has revealed more prehistoric secrets of how the species survived in its icy habitat.
The mammoth, known as Lyuba, was about a month old when she died in the Siberian tundra, where she remained until she was discovered by reindeer herders three years ago. Her body was so well preserved in the permafrost that her stomach retained traces of her mother’s milk, and scientists identified sediment in her mouth, trunk and throat — suggesting that she suffocated while struggling to free herself from the mud.

Our Changing View Of The Moon
The first drawing of the Moon through a telescope, dated July 26, 1609, by Thomas Harriot. This crude but historic sketch roughly delineates the terminator, the line that marks the boundary between day and night on the lunar surface. The original image is a little more than 15 cm across. The dark patches correspond to Mare Crisium (at the top), Mare Tranquilitatis and Mare Foecunditatis. © Lord EgremontFrom MSNBC:
The moon, so bright and large in the sky compared to other celestial objects, has captured the attention of humans at least since the dawn of consciousness. Over these eras, mankind's view of the moon has evolved, from the more mystical image of it as a god, to the thought it was covered in seas and vegetation. Most recently, it's been viewed as a dry and dusty wasteland.
Recent findings of water on the lunar surface could spur yet another shift in the way we see our orbiting companion.
The moon appears in early art thousands of years ago, showing that early man was as enthralled by its eerie glow as later philosophers and scientists.
Gene Controlling Number Of Brain Cells Pinpointed
A new study suggests that a single gene, called GSK-3, controls the signals that determine how many neurons actually end up composing the brain. (Credit: Image courtesy of University of North Carolina School of Medicine)From Science Daily:
Science Daily (Oct. 5, 2009) — In populating the growing brain, neural stem cells must strike a delicate balance between two key processes – proliferation, in which the cells multiply to provide plenty of starting materials – and differentiation, in which those materials evolve into functioning neurons.
If the stem cells proliferate too much, they could grow out of control and produce a tumor. If they proliferate too little, there may not be enough cells to become the billions of neurons of the brain. Researchers at the University of North Carolina at Chapel Hill School of Medicine have now found that this critical balance rests in large part on a single gene, called GSK-3.

Mammoth Black Holes Push Universe To Its Doom
Speaking of black holes, what could be stranger?Beyond a black hole's gravitational border -- or event horizon -- neither matter nor light can escape. Astrophysicists think dying stars about three to 20 times the mass of the sun can form these strange objects. At the center of galaxies, black holes about 10,000 to 18 billion times heavier than the sun are thought to exist, enlarged by gobbling up gas, dust, stars and small black holes.
What about mid-sized types? Perhaps surprisingly, evidence is both scarce and questionable for their existence.

From New Scientist:
THE mammoth black holes at the centre of most galaxies may be pushing the universe closer to its final fade-out. And it is all down to the raging disorder within those dark powerhouses.
Disorder is measured by a quantity called entropy, something which has been on the rise ever since the big bang. Chas Egan and Charles Lineweaver of the Australian National University in Canberra used the latest astrophysical data to calculate the total entropy of everything in the universe, from gas to gravitons. It turns out that supermassive black holes are by far the biggest contributors to the universe's entropy. Entropy reflects the number of possible arrangements of matter and energy in an object. The number of different configurations of matter a black hole could contain is staggering because its internal state is completely mysterious.

Mitochondrial Death Channels
Figure 1. A 53-year-old patient experiencing sporadic discomfort undergoes a coronary angiogram. The results are ominous. Severe stenosis (narrowing) is visible in the pinched regions (top middle), indicating the buildup of fatty deposits within the artery. If a wandering clot blocks the pinhole opening of a nearly clogged vessel, a heart attack ensues. With bloodflow blocked, cardiac cells downstream are starved for oxygen, leading to drastic metabolic changes as the cells struggle to survive. The most important changes affect mitochondria, the powerhouses of cell metabolism. The inset shows mitochondria (orange) arrayed among cardiac muscle fibrils (blue), where they are positioned to supply a steady stream of ATP to contracting muscle. Under oxidative stress, the mitochondria can also release potent effectors that lead directly to apoptosis—cell suicide. The trigger for the opening of the so-called mitochondrial death channels is, ironically, the return of oxygen to starved tissue during reperfusion. Learning to control the activities of the death channels could vastly improve the outlook for heart attack victims.Top image by Zephyr/Photo Researchers, Inc.; bottom image by Steve Gschmeissner/Photo Researchers, Inc.
From American Scientist:
In heart attacks, cells die if they aren’t perfused with fresh oxygen—and kill themselves if they are. Understanding cell suicide may greatly improve outcomes.
Coronary artery disease is the leading cause of morbidity and mortality in North America and Europe. More than 12 million people in the United States have coronary artery disease, and more than 7 million have had a myocardial infarction (heart attack). Chronic stable angina (chest pain) is the initial manifestation of coronary artery disease in approximately half of all presenting patients, and about 16.5 million Americans (more than 5 percent) currently have stable angina.
