New Analyses Of Dinosaur Growth May Wipe Out One-third Of Species
http://feeds.sciencedaily.com/~r/sciencedaily/~3/huvAB4VXvnA/091031002314.htm
Paleontologists Mark Goodwin and Jack Horner have dug for 11 years in Montana's Hell Creek Formation in search of every dinosaur fossil they can find, accumulating specimens of all stages of development. Their new report on the growth stages of dome-headed dinosaurs shows that two named species are really just young pachycephalosaurs. They say that perhaps one-third of all named dinosaurs may not be separate species, but juvenile or subadult stages of other known dinosaurs.

New DNA Method Makes It Easier To Trace Criminals
http://feeds.sciencedaily.com/~r/sciencedaily/~3/Dciq88yLe70/091029155956.htm
DNA samples often convict criminals. But many of today's forensic tests are so polluted by soil, tobacco and food remains, for example, that they can not be used. Now researchers in Sweden have improved a critical part of the analysis process. The first findings indicate that the new method strengthens the DNA analysis so that previously negative samples yield positive and usable DNA profiles.

Interactions With Aerosols Boost Warming Potential Of Some Gases
http://feeds.sciencedaily.com/~r/sciencedaily/~3/3mwO7DrJW3w/091030100020.htm
For decades, climate scientists have worked to identify and measure key substances -- notably greenhouse gases and aerosol particles -- that affect Earth's climate. And they've been aided by ever more sophisticated computer models that make estimating the relative impact of each type of pollutant more reliable. Yet the complexity of nature -- and the models used to quantify it -- continues to serve up surprises. The most recent? Certain gases that cause warming are so closely linked with the production of aerosols that the emissions of one type of pollutant can indirectly affect the quantity of the other. And for two key gases that cause warming, these so-called "gas-aerosol interactions" can amplify their impact.

Placental Precursor Stem Cells Require Testosterone-free Environment To Survive
http://feeds.sciencedaily.com/~r/sciencedaily/~3/jmIyynnJfEs/091029102430.htm
Trophoblast stem cells, found in the layer of peripheral embryonic stem cells from which the placenta is formed, are thought to exhibit "immune privilege" that aids cell survivability and is potentially beneficial for cell and gene therapies. Survivability of TSCs has been thought to require the presence of ovarian hormones. This study, however, demonstrates that it is the absence of male hormones, rather than the presence of female hormones, that allows extended transplanted cell survivability.

http://feeds.sciencedaily.com/~r/sciencedaily/~3/CoycHf6kvpU/091021115157.htm
Researchers have found a genetic "switch" in fruit flies that plays an important role in making flies more tolerant to alcohol. This metabolic switch also has implications for the deadly liver disease cirrhosis in humans. A counterpart human gene contributes to a shift from metabolizing alcohol to the formation of fat in heavy drinkers. This shift can lead to fatty liver syndrome -- a precursor to cirrhosis.

Researchers Discover RNA Repair System In Bacteria
http://feeds.sciencedaily.com/~r/sciencedaily/~3/fI4UQyLkPcg/091012225811.htm
Researchers have discovered the first RNA repair system to be discovered in bacteria. The novelty of the newly discovered bacterial RNA repair system is that, before the damaged RNA is sealed, a methyl group is added to the two-prime hydroxyl group at the cleavage site of the damaged RNA, making it impossible to cleave the site again. Thus, the repaired RNA is "better than new."

Elderly people exhibiting memory disturbances that do not affect their normal, daily life suffer from a condition called "mild cognitive impairment" (MCI). Some MCI patients go on to develop Alzheimer's disease within a few years, whereas other cases remain stable, exhibiting only benign senile forgetfulness. It is crucial to develop simple, blood-based tests enabling early identification of these patients that will progress in order to begin therapy as soon as possible, potentially delaying the onset of dementia.

New Understanding Of Why Seizures Occur With Alcohol Withdrawal
http://feeds.sciencedaily.com/~r/sciencedaily/~3/a1XwvN_d8g4/091018141720.htm
Epileptic seizures are the most dramatic and prominent aspect of the "alcohol withdrawal syndrome" that occurs when a person abruptly stops a long-term or chronic drinking habit. Researchers have shown that the flow of calcium ions into brain cells via voltage-gated calcium channels plays an important role in the generation of alcohol withdrawal seizures, because blocking this flow suppresses these seizures. But do the changes in calcium currents contribute to alcohol withdrawal seizures or are they a consequence of the seizures?

Whereas the master clock in the brain is set by light, the pacemakers in peripheral organs are set by food availability. The underlying molecular mechanism was unknown. Now, researchers are shedding light on the long missing connection: A metabolic master switch, which, when thrown, allows nutrients to directly alter the rhythm of peripheral clocks.

Scientists Remove Amyloid Plaques From Brains Of Live Animals With Alzheimer's Disease
http://feeds.sciencedaily.com/~r/sciencedaily/~3/lQo-l8gc0k8/091015091602.htm
A breakthrough discovery in mice may lead to a new treatment for Alzheimer's disease that actually removes amyloid plaques -- considered a hallmark of the disease -- from patients' brains. This discovery is based on the unexpected finding that when the brain's immune cells (microglia) are activated by the interleukin-6 protein (IL-6), they actually remove plaques instead of causing them or making them worse.

When researchers genetically tweaked fruit flies so that they didn't produce certain pheromones, they triggered a sexual tsunami in their laboratory. In fact, they produced bugs so irresistible that normal male fruit flies attempted to mate with pheromone-free males and even females from a different species -- generally a no-no in the fruit fly dating scene.

Researchers have for the first time identified the genetic mechanisms involved in the formation and survival of L-form bacteria. L-form bacteria, which were first discovered in the 1930s, are morphological variants of classical bacteria that lack a cell wall. These bacteria are believed to form in response to cell wall stress from certain antibiotics or the body's immune attack, and are suspected to be associated with antibiotic-resistant infections.

Silicon, the most important semiconductor material of all, is usually considered to be as brittle and breakable as window glass. On the nanometer scale, however, the substance exhibits very different properties, as Swiss researchers have shown by creating minute silicon pillars. If the diameters of the columns are made small enough, then under load they do not simply break off, as large pieces of silicon would, but they yield to the pressure and undergo plastic deformation, as a metal would. This discovery opens the way for completely new design techniques from a materials point of view for mechanical microsystems and in the watch industry.

The role of the forests is assumed to increase in the future, as an important buffer of climate change and increasing carbon dioxide concentrations. So-called Earth system models, computer systems making predictions for the globe, estimate that this effect can be very large. However, new research results, based on measurements at hundreds of European forests, indicate that predicted effects by these models are overestimated because they ignore the limitation of nitrogen. It makes the current predictions by Earth system models more than twice as high as they most likely will be.

A Simple Way For Older Adults To Assess Arterial Stiffness: Reach For The Toes
http://feeds.sciencedaily.com/~r/sciencedaily/~3/YTj_cP8OJLI/091006093345.htm
How far you can reach beyond your toes from a sitting position -- normally used to define the flexibility of the body -- may be an indicator of how stiff your arteries are. Because arterial stiffness often precedes cardiovascular disease, the results suggest that this could become a quick measure of a person's risk for heart attack or stroke.

Come On In: Nuclear Barrier Less Restrictive Than Expected In New Cells
http://feeds.sciencedaily.com/~r/sciencedaily/~3/xG9BC4pFetc/091006122326.htm
When it comes to the two basic types of cells, prokaryotes and eukaryotes, compartmentalization is everything. Prokaryotes are evolutionarily ancient cells that only have a membrane surrounding their outer boundary, while the more complex eukaryotes have an outer membrane and membrane bound compartments within the cell. Perhaps most notable is the double layered membrane that surrounds the nucleus, the cellular compartment which houses the cell's genetic material.

Sand Dunes Reveal Unexpected Dryness During Heavy Monsoon
http://feeds.sciencedaily.com/~r/sciencedaily/~3/EzvZu76n2CQ/091006134831.htm
The windswept deserts of northern China might seem an odd destination for studying the heavy monsoon rains that routinely drench the more tropical regions of Southeast Asia. But the sandy dunefields that mark the desert margin between greener pastures to the south and the Gobi Desert to the north are a rich source of information about past climates in Asia. Wetter periods allow vegetation to take root on and stabilize sand dunes. During dry spells, plants die off and the dunes are more active, constantly shifting as sand is blown away and replenished.
