Scientists explain puzzling lake asymmetry on Saturn's moon Titan
http://feeds.sciencedaily.com/~r/sciencedaily/~3/qzUEgie82A4/091129153401.htm
Researchers suggest that the eccentricity of Saturn's orbit around the sun may be responsible for the unusually uneven distribution of methane and ethane lakes over the northern and southern polar regions of the planet's largest moon, Titan. On Earth, similar "astronomical forcing" of climate drives ice-age cycles.

New fossil plant discovery links Patagonia to New Guinea in a warmer past
http://feeds.sciencedaily.com/~r/sciencedaily/~3/f8iqPZKeJQ8/091110171750.htm
Fossil plants provide clues as to what our planet looked like millions of years ago. Identifying fossil plants can be tricky, however, when plant organs fail to be preserved. Researchers recently discovered abundant fossilized specimens of a conifer (previously known as "Libocedrus" prechilensis) found in Argentinean Patagonia. Characteristics of these fossils match those currently found only in tropical, montane New Guinea and the Moluccas. This discovery helps to explain the remarkable plant and insect diversity found in Eocene Patagonia.

Rare woodland plant uses 'cryptic coloration' to hide from predators
http://feeds.sciencedaily.com/~r/sciencedaily/~3/hnuM6LKo8iQ/091125145825.htm
It is well known that some animal species use camouflage to hide from predators. Individuals that are able to blend in to their surroundings and avoid being eaten are able to survive longer, reproduce, and thus increase their fitness (pass along their genes to the next generation) compared to those who stand out more. This may seem like a good strategy, and fairly common in the animal kingdom, but who ever heard of a plant doing the same thing?

http://feeds.sciencedaily.com/~r/sciencedaily/~3/_Asa_7CVUoU/091109142116.htm
The practice of sterilizing medical tools and devices helped revolutionize health care in the 19th century because it dramatically reduced infections associated with surgery. Through the years, numerous ways of sterilization techniques have been developed, but the old mainstay remains a 130-year-old device called an autoclave, which is something like a pressure steamer. Now researchers in the Netherlands are developing a new way to sterilize medical devices by sealing them inside plastic bags and then using electromagnetic fields to create plasmas -- partially ionized gasses that contain free electrons and reactive ions.

People with multiple sclerosis (MS) feel more than twice as much withheld anger as the general population, but expressed anger levels are similar. Researchers were surprised by the results from the 195 MS patients. They also found that elevated withheld anger levels were not related to the severity of the patients' MS. This suggests that these inconsistent changes were caused by nervous system damage, rather than an emotional reaction to the stress of the disease.

How crops survive drought
http://feeds.sciencedaily.com/~r/sciencedaily/~3/uqDCYknZguY/091118143255.htm
Breakthrough research done earlier this year by a plant cell biologist has greatly accelerated scientists' knowledge on how plants and crops can survive difficult environmental conditions like drought. In drought conditions certain receptor proteins in plants perceive ABA, causing them to inhibit an enzyme called a phosphatase. The receptor protein is at the top of a signaling pathway in plants, functioning like a boss relaying orders to the team below that then executes particular decisions in the cell. Now recent published studies show how those orders are relayed at the molecular level.

Like all tissues in the body, the eye needs a healthy blood supply to function properly. Poorly developed blood vessels can lead to visual impairment or even blindness. While many of the molecules involved in guiding the development of the intricate blood vessel architecture are known, only now are we learning how these molecules work and how they might affect sight. Researchers have now found that when some cells in the mouse retina are not properly fed by blood vessels, they can remain alive for many months and can later recover some or all of their normal function, suggesting that similar conditions in people may also be reversible.

Increasing temperatures at high altitudes are fueling the post-1950 growth spurt seen in bristlecone pines, the world's oldest trees, according to new research. The pines near treeline have wider annual growth rings for the period from 1951 to 2000 than for the previous 3,700 years. Regional temperatures, particularly at high elevations, have increased during the same 50-year time period. The finding is another example of changes in high-elevation ecosystems that are linked to warming temperatures.

New Brain Findings On Dyslexic Children: Good Readers Learn From Repeating Auditory Signals, Poor Readers Do Not
http://feeds.sciencedaily.com/~r/sciencedaily/~3/k-ljrEGNJiU/091111123600.htm
The vast majority of school-aged children can focus on the voice of a teacher amid the cacophony of the typical classroom thanks to a brain that automatically focuses on relevant, predictable and repeating auditory information, according to new research. But for children with developmental dyslexia, the teacher's voice may get lost in the background noise of banging lockers, whispering children, playground screams and scraping chairs, the researchers say.

Nano Bubble Gum For Enhancing Drug Delivery In Gut
http://feeds.sciencedaily.com/~r/sciencedaily/~3/oRtcAklTnmQ/091109142121.htm
Of the many characteristic traits a drug can have, one of the most desirable is the ability for a drug to be swallowed and absorbed into the bloodstream through the gut. Some drugs, like over-the-counter aspirin, lend themselves to this mode of delivery and are trivial to take. They can be pressed into a pill and swallowed. Other drugs cannot be swallowed and must be administered instead through more complicated routes. Insulin, for instance, must be injected.

Unexpected Properties Of Nanostructures: When Holes Obscure The View
http://feeds.sciencedaily.com/~r/sciencedaily/~3/48Se_F2J6Zo/091111110854.htm
Metals are opaque: they reflect light almost completely. For that reason they are utilized as mirrors; as films deposited onto a glass -- you find them in any bathroom. If the metal film is very thin, the mirror is semitransparent. These half-silvered mirrors help to hide surveillance video cameras, for instance. One might think that holes in a metal film enhance the view. Exactly the opposite is true. Physicists discovered that tiny holes actually make the metal opaque.

Rapid Supernova Could Be New Class Of Exploding Star
http://feeds.sciencedaily.com/~r/sciencedaily/~3/Lb3hlG9KB5Q/091105143718.htm
Astronomers were looking through seven-year-old data when they chanced upon a very strange supernova that flashed and was gone in less than a month, when 3-4 months is typical. The unusually rapid supernova appears to match the predicted behavior of a thermonuclear explosion on a white dwarf that is drawing helium from its binary companion. This mechanism is quite different from the two standard types of supernovae.

'Duck-billed' Dinosaurs: Last European Hadrosaurs Lived In Iberian Peninsula
http://feeds.sciencedaily.com/~r/sciencedaily/~3/RoNzIdlHZw8/091105102726.htm
Spanish researchers have studied the fossil record of hadrosaurs, the so-called "duck-billed" dinosaurs, in the Iberian Peninsula for the purpose of determining that they were the last of their kind to inhabit the European continent before disappearing during the K/T extinction event that occurred 65.5 million years ago. Most notable among these fossils is the discovery of a new hadrosaur, the Arenysaurus ardevoli, found in Huesca, Spain.

Hybrid Molecules Show Promise For Exploring, Treating Alzheimer's
http://feeds.sciencedaily.com/~r/sciencedaily/~3/cD331U65NBg/091104101551.htm
One of the many mysteries of Alzheimer's disease is how protein-like snippets called amyloid-beta peptides, which clump together to form plaques in the brain, may cause cell death, leading to the disease's devastating symptoms of memory loss and other mental difficulties. In order to answer that key question and develop new approaches to preventing the damage, scientists must first understand how amyloid-beta forms the telltale clumps. Researchers have now developed new molecular tools that can be used to investigate the process.

Lightning's 'NOx-ious' Impact On Pollution, Climate
http://feeds.sciencedaily.com/~r/sciencedaily/~3/2zZ12Z1nUlc/091030100022.htm
More than 1.2 billion lightning flashes occur around the world every year. Each of those billion lightning flashes produces a puff of nitrogen oxide gas (NOx) that reacts with sunlight and other gases in the atmosphere to produce ozone. Using data gleaned from aircraft observations and satellites, NASA scientists recently took steps toward a better global estimate of lightning-produced NOx and found that lightning may have a considerably stronger impact on the climate in the mid-latitudes and subtropics.

Are The Alps Growing Or Shrinking?
http://feeds.sciencedaily.com/~r/sciencedaily/~3/O8KokQM0aJc/091105121207.htm
The Alps are growing just as quickly in height as they are shrinking. This paradoxical result comes from a new study by a group of German and Swiss geoscientists. Due to glaciers and rivers, about exactly the same amount of material is eroded from the slopes of the Alps as is regenerated from the deep Earth's crust. The climatic cycles of the glacial period in Europe over the past 2.5 million years have accelerated this erosion process.
