Genetics Wonders : New Organisms of 2007

Maybe you wonder instantly what "new organisms" mean.

It means that totally new creatures that didn't exist before 01.01.2007. Yes, you have heard correctly.

New Study Shows Beetles Amazing Success Story

A new evolutionary study has shown. that beetles are much stronger than we thought and first appeared on Earth at the same time as the earliest dinosaurs and survived until our time

Today, there are an estimated 350,000 known species of beetle on Earth, and probably several million more yet to be discovered, say scientists. The insects account for about a quarter of all life forms on the planet.

The new research shows that modern beetle lineages go back further than anyone suspected, even pre-dating the emergence of flowering plants. Previously it had been assumed that the beetles' success story was partly due to flowers which started to bloom in the Cretaceous period, from around 140 million years ago.

Flowering plants were thought to have provided beetles with new sources of food and habitats.

But according to the latest findings many of today's beetle families originated during the earlier Jurassic period, which also saw the appearance of the first major groups of dinosaurs.

Beetles first entered the fossil record in the Lower Permian period, nearly 300 million years ago.

Study leader Professor Alfried Vogler, from Imperial College London and the Natural History Museum, said: "The large number of beetle species existing today could very well be a direct result of this early evolution and the fact that there has been a very high rate of survival and continuous diversification of many lineages since then."

Prof Vogler's team used DNA sequencing and fossil records to compile a comprehensive evolutionary "family tree" for beetles.

By comparing the DNA of 1,880 different beetle species, the scientists were able to identify those which descended from a common ancestor. Fossils of known ages were used to date key moments of evolution and diversification on the ancestral tree.

While the dinosaurs became extinct 65 million years ago, beetles have continued to flourish, evolving into a plethora of different shapes and sizes.

Asteroid can hit Mars in late January, 1/75 Chances

A newly discovered space rock has a 1 in 75 chance of slamming into the Red Planet on Jan. 30, scientists said Thursday.

"These odds are extremely unusual. We frequently work with really long odds when we track ... threatening asteroids," said Steve Chesley, an astronomer with the Near Earth Object Program at NASA's Jet Propulsion Laboratory.

The asteroid, known as 2007 WD5, was discovered in late November and is similar in size to the Tunguska object that hit remote central Siberia in 1908, unleashing energy equivalent to a 15-megaton nuclear bomb that wiped out 60 million trees.

Scientists tracking the asteroid, which is halfway to Mars, initially put the odds of impact at 1 in 350 and increased the chances this week after analyzing the data. Scientists expect the odds to diminish again early next month after getting new observations of the asteroid's orbit, Chesley said.

"We know that it's going to fly by Mars and most likely going to miss, but there's a possibility of an impact," he said.

If the asteroid does smash into Mars, it'll likely aim near the equator close to where the rover Opportunity has been exploring the Martian plains since 2004. The robot is not in danger because it lies outside the impact zone. Speeding at 8 miles a second, a collision would carve a hole the size of the famed Meteor Crater in Arizona.

In 2004, fragments of the comet Shoemaker-Levy 9 smacked into Jupiter, creating a series of overlapping fireballs in space. Astronomers have yet to witness an asteroid impact with another planet.

"Unlike an Earth impact, we're not afraid, but we're excited," Chesley said.

Interesting Natural Phenomenon -- The red tide

"Red tide is an estuarine or marine algal bloom [a relatively rapid increase in the population of (usually) phytoplankton algae in an aquatic system] and is caused by a species of dinoflagellates, often present in sufficient numbers (thousands or millions of cells per milliliter) to turn the water red or brown. Coastal water pollution produced by humans and systematic increase in sea water temperature appear to be causal factors in red tides. On the Pacific Coast of the U.S. there have been apparent increases in the occurrence of red tides since about 1991. These increases are correlated with a marine temperature rise of about one degree Celsius, and also with increased nutrient loading into ocean waters. Additionally, red tide can assume its dormant form if the water cools to a sufficient degree. When it does this it forms cysts which drop to the ocean floor and rebloom if the right conditions occur."(Read more)

things -- the phytoplankton algae.
frameworks -- the thousands or millions of phytoplankton cells that come together.c
lockworks -- water pollution and a decrease water temperature cause this event to happen. it can come and go whenever these situations are present.

Have you ever seen such cloud formations ?!

A very interesting photo taken December 11, 2003 in Alabama.

It is a natural event called as "Hole Punch" Clouds.
