Yi qi : Is it a Bird or is it a Bat……It’s a dinosaur…!!!

(CNN)Chinese scientists say they have discovered a new dinosaur species, with bat-like wings, that sheds light on how dinosaurs may have evolved into birds.

Based on a fossil specimen discovered in China’s Hebei province a decade ago, scientists estimate the bird-like dinosaur existed for a very short time 160 million years ago during the Jurassic Period, according to a new paper published in scientific journal Nature on Wednesday.

The odd feathered creature discovered in China is thought to have had leathery wings similar to those of bats but never before seen in a dinosaur.

yi-qi-reconstruction1000Named “Yi qi” – Mandarin for “strange wing” – the tiny aviator weighing less than a pound (380 grams) lived during the Jurassic Period 160 million years ago.

Its feathers were not associated with flight, but Yi qi had a peculiar long rod-like bone extending from each wrist.

Experts think it probably supported a wing membrane, as seen in bats and gliding flying squirrels. Their theory is supported by the discovery of patches of membranous tissue preserved in the fossil remains.

Lead researcher Professor Xing Xu, from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) in Beijing, said: “We thought giving this animal a name meaning ‘strange wing’ was appropriate, because no other bird or dinosaur has a wing of the same kind.

“We don’t know if Yi qi was flapping, or gliding, or both, but it definitely evolved a wing that is unique in the context of the transition from dinosaurs to birds.”

The scientists, whose findings are reported in the journal Nature, believe Yi qi was one of nature’s early pioneers of flight – an evolutionary experiment that ultimately failed.

The International Space Station is the result of an amazing collaboration of many countries and countless individuals from around the world, a research lab and symbol of global peace and partnership put together in space. But recent and growing political tension between the two biggest contributors to the ISS – the United States and Russia – are casting doubt on the status of Station’s future. Will Russia continue its support of the ISS? Or will they build their own space station like some reports have suggested? And if so, what will happen to the current Station?

Ron Garan, former NASA astronaut and ISS crew member, humanitarian, and author of the new book The Orbital Perspective, is featured in a webcomic by Andy Warner (perhaps in honor of Free Comic Book Day?) called “Atmospheric Breakup,” which addresses the…

Diseased Tomato Plants ??

Can Anyone Identify what disease is this and how can we control it ?


The leaves of the Tomato crop have spots, which are small, circular to angular, isolated, scattered and pale brown to black in color. These spots seem to be surrounded by a narrow chlorotic zone in some cases. Some of them also have brown lesions near the stem base. A few plants are completely defoliated. There is a picture below showing the situation.

I posted about this article in various social networking sites with an urge to discover more about this disease. I found a good amount of knowledge of the disease and its control measures.
