Amazing striped icebergs Icebergs in the Antarctic area sometimes have stripes, formed by layers of snow that react to different conditions. Blue stripes are often created when a crevice in the ice sheet fills up with meltwater and freezes so quickly that no bubbles form. When an iceberg falls into the sea, a layer of salty seawater can freeze to the underside. If this is rich in algae, it can form a green stripe. Brown, black and yellow lines are caused by sediment, picked up when the ice sheet grinds downhill towards the sea. |

Why do stingrays and other aquatic creatures leap through the air?

"According to court documents, Isenhour got upset when a red-shouldered hawk began making noise, forcing another take. He began hitting balls at the bird, then 300 yards away, but gave up. Isenhour started again when the hawk moved within about 75 yards, Florida Fish and Wildlife Conservation Commission officer Brian Baine indicated in a report.
Isenhour allegedly said, "I'll get him now," and aimed for the hawk."

These newfound enigmas join the so-called "Pioneer anomaly" as hints that unexplained forces may appear to act on spacecraft.
A decade ago, after rigorous analyses, anomalies were seen with the identical Pioneer 10 and 11 spacecraft as they hurtled out of the solar system. Both seemed to experience a tiny but unexplained constant acceleration toward the sun.
A host of explanations have been bandied about for the Pioneer anomaly. At times these are rooted in conventional science — perhaps leaks from the spacecraft have affected their trajectories. At times these are rooted in more speculative physics — maybe the law of gravity itself needs to be modified.
Now Jet Propulsion Laboratory astronomer John Anderson and his colleagues — who originally helped uncover the Pioneer anomaly — have discovered that five spacecraft each raced either a tiny bit faster or slower than expected when they flew past the Earth en route to other parts of the solar system."

"A campaign has been launched to build a permanent memorial to a bear which spent much of its life in Scotland - after fighting in World War II.
The bear - named Voytek - was adopted in the Middle East by Polish troops in 1943, becoming much more than a mascot.
The large animal even helped their armed forces to carry ammunition at the Battle of Monte Cassino.
Voytek - known as the Soldier Bear - later lived near Hutton in the Borders and ended his days at Edinburgh Zoo.
He was found wandering in the hills"

That millions of butterflies annually fly a few thousand miles to reach a cluster of pine groves in central Mexico comprising just 70 square miles is, for many, an awesome and mysterious occurrence. However, over the past two decades, scientists have begun to unveil the journey for what it is: a spectacular result of biology, driven by an intricate molecular mechanism in a tiny cluster of cells in the butterfly brain."

"On December 24, 2007, the website Space.com published a report entitled, "The Enduring Mysteries of Comets." The premise is intriguing, since it is rare for science media to acknowledge that "mysteries" of any real significance exist for conventional theories. Unfortunately, the report mentions few of the recent discoveries that have thrown the popular "dirty snowball" model of comets into disarray.
"We have now had four close encounters with comets, and every one of them has thrown astronomers onto their back foot." -Stuart Clark, New Scientist, September 09, 2005."
