"These large bees are the first soldier bees to be discovered by scientists. "Researchers at the University of Sussex discovered these unique bees that guard the nests of Jatai bees (Tetragonisca angustula). Jatai bees live in trees and small cavities throughout Brazil.

In the video you can see them circling around the entrance to the nest. Jatai soldier bees are heavier -- they have larger legs but smaller bodies -- and they do not have the ability to sting. Instead, they provide a warning system for the other bees against attacks by predators, such as robber bees (Lestrimelitta limao). Robber bees simply come into a hive and steal honey but a full-scale attack can destroy an entire colony. Despite being stingless, the soldier bees are able to fight off robber bee scouts looking for a meal by clamping onto the wings and preventing them from flight.""

"This is the first animated adaptation of The Hobbit. It was created by Gene Deitch after his hopes at creating a feature-length animation were squashed. His producer had him complete it in a month so that he wouldn't lose the film rights to the entire Tolkien series."

"Two spiral arms emerge from the gas-rich disk around SAO 206462, a young star in the constellation Lupus. This image, acquired by the Subaru Telescope and its HiCIAO instrument, is the first to show spiral arms in a circumstellar disk. The disk itself is some 14 billion miles across, or about twice the size of Pluto's orbit in our own solar system.

This recent discovery of a star with spiral arms startled researchers using the Subaru telescope in Hawaii. SAO 206462 is more than four hundred light years from Earth in the constellation Lupus, the wolf."

"Medical science has come a long way in the 20th and 21st centuries and a few of the most important innovations have paved the way for a future of medical discoveries. Smallpox alone killed more than 500,000,000 people. In the 18th century, nearly half a million people succumbed to the disease every year. The smallpox vaccine is just one of many medical discoveries that helped save millions of lives. Here are a few of history’s top discoveries."

Opportunity investigates Tisdale 2 : Clues to Ancient Water Flow on Mars

Bright veins cutting across outcrop in a section of Endeavour crater's rim called "Botany Bay" are visible in the foreground and middle distance of this view assembled from images taken by the navigation camera on Opportunity during Sol 2,681on Mars (Aug. 9, 2011).

Opportunity Traverse Map: 2004 to 2011. The yellow line on this map shows where NASA's Mars Rover Opportunity has driven from the place where it landed in January 2004 -- inside Eagle crater, at the upper left end of the track -- to a point approaching the rim of Endeavour crater. The map traces the route through the 2,670th Martian day, or sol, of Opportunity's work on Mars (July 29, 2011).

This image taken from orbit shows the path of the path driven by NASA's Mars Exploration Rover Opportunity in the weeks around the rover's arrival at the rim of Endeavour crater. The sol number (number of Martian days since the rover landed on Mars) are indicated along the route. Sol 2674 corresponds to Aug. 2, 2011; Sol 2688 corresponds to Aug. 16, 2011

This rock, informally named "Tisdale 2," was the first rock the NASA's Mars Rover Opportunity examined in detail on the rim of Endeavour crater. It has textures and composition unlike any rock the rover examined during its first 90 months on Mars. Its characteristics are consistent with the rock being a breccia -- a type of rock fusing together broken fragments of older rocks.

"Opportunity has begun a whole new mission at Endeavour Crater promising a boatload of new science discoveries.

Scientists directing NASA’s Mars Opportunity rover gushed with excitement as they announced that the aging robot has discovered a rock with a composition unlike anything previously explored on the Red Planet’s surface – since she landed on the exotic Martian plains 7.5 years ago – and which offers indications that liquid water might have percolated or flowed at this spot billions of years ago.

Barely three weeks ago Opportunity arrived at the rim of the gigantic 14 mile ( 22 km) wide crater named Endeavour after an epic multi-year trek, and for the team its literally been like a 2nd landing on Mars – and the equivalent of the birth of a whole new mission of exploration at an entirely ‘new’ landing site."

Holden and Eberswalde Craters

Eberswalde Crater in Context

Delta in Eberswalde Crater

Eberswalde Crater in Perspective

Holden Crater in Perspective

2 September 2011
ESA’s Mars Express has spotted a rare case of a crater once filled by a lake, revealed by the presence of a delta. The delta is an ancient fan-shaped deposit of dark sediments, laid down in water. It is a reminder of Mars’ past, wetter climate.

The delta is in the Eberswalde crater, in the southern highlands of Mars. The 65 km-diameter crater is visible as a semi-circle on the right of the image and was formed more than 3.7 billion years ago when an asteroid hit the planet.

This article will examine ten geological discoveries that have made headlines in the scientific world. The events have all occurred in the last 15,000 years, which is recent in terms of the geologic time scale.

"The largest known rock transported by the Missoula Floods is pictured, located on the Ephrata Fan, near Soap Lake, Washington...."The water flow was nine cubic miles per hour, more than ten times the combined flow of every river in the world. Maximum discharge was about 1.3 billion gallons per second, about 1,000 times the Columbia River’s current average flow."...

Glow-in-the-dark Neonothopanus gardneri rediscovered after 170 years.

"In 1840, English botanist George Gardner was traveling in Brazil. One night, he noticed some boys playing with a strange, glowing object. To his shock, he had encountered a bioluminescent mushroom. It's only taken 170 years to find some more. After Gardner sent a sample of the fungus to Kew Herbarium in England, it pretty much disappeared completely, and it's now thanks to biologists at San Francisco State that we've finally found some more."

"Astronomers are still unsure of where Phobos came from. Did it form with Mars as a planet? Is it a captured asteroid, now trapped in orbit? Or is Phobos a chunk of Mars flung into orbit from an impact? (Or… maybe it’s an ancient alien spacecraft?? Just kidding.) Wherever it came from, as a moon Phobos is an oddity. In addition to its small size – only 16 miles across at its widest – low reflectivity (albedo) and irregular shape, it orbits its parent planet at a rather low altitude, only 5,840 miles (as compared to our own Moon’s 248,000 mile distance) and thus needs to travel at a very high speed in order to stay in orbit. It is actually orbiting Mars overthree times faster than Mars rotates, and rises in Mars’ western sky. Its orbit is so low, in fact, that it can’t even be seen from the polar regions on Mars !"
