Solar Storms


This 2006 Solar and Heliospheric Observatory (SOHO) Extreme ultraviolet Imaging Telescope (EIT) image shows a flare on the Sun. An unusual solar flare observed by a NASA space observatory on Tuesday could cause some disruptions to satellites, communications and power on Earth over the next day or so, officials said. An eruption of similar magnitude has not been witnessed since 2006.


IN SPACE - JUNE 7: In this handout from NASA/Solar Dynamics Observatory, a solar large flare erupts off the sun June 7, 2011 in space. A large cloud of particles flew up and then was pulled back down to the sun's surface. According to NASA, the event is not suppose have any effect once the particles reach the earth on either June 8 or June 9. (Photo by NASA/Solar Dynamics Observatory via Getty Images).

Cooling molecules Earth

Scientists have long predicted the existence of molecular cooling the Earth. The presence of molecules that ultimately proved successful. Molecule called Criegee biradikal.

Researchers from the University of Manchester, University of Bristol and Sandia National Laboratories is able to prove its existence. They say that the Criegee biradikal is able to oxidize pollutants such as nitrogen dioxide and sulfur dioxide from combustion.

The presence of these molecules was detected using the light from the third generation synchroton facility at the Advanced Light Source at Lawrence Berkeley National Laboratory.

The intense light and can be adjusted from synchroton it allows scientists to distinguish different types of isomers, molecules consisting of the same atoms but have different arrangements.

Mathematicians Reveal Eating Behavior Bees

Mathematicians of the Queen Mary School of Mathematical Sience, Rainer Klages and Lars Chittka of the School of Biological and Chemical Science, UK revealed that bees have a unique fly patterns.

Both scientists are observing the behavior of bees while foraging. The results were published in the journal Physical Review Letters this month.

Bees are known to have visited some flower nectar. Occasionally visited by some direct interest to get it. Researchers tested how predators influence such behavior.

"In mathematics, we treat the bees as random objects moving toward the target which is also distributed at random," Klages said as quoted by the site Physorg, Friday (03/02/2012) then.

Snake scales

Scales is key to the snakes in a move that can prevent slipping while on slippery surfaces. Hamid concluded Marvi, a biologist from the Georgia Institute of Technology in Atlanta, USA, after doing research tekait functions snake scales.

In the first experiment, Marvi anesthetize snakes are moving and tilting motion of the surface so that the snake fell off. Meanwhile, a second experiment, Marvi disturb the snake's motion to be dropped without him sedated.

In each experiment, Marvi measure the angle and the coefficient of friction is created between the scales and the surface motion. The results showed that the coefficient of friction when the serpent realized 2-fold greater than when anesthetized snakes.

"When the snake did not realize, no controls, no response, no sensory system. But when the snake came to, he could feel. I'm moving so I had to do something. There is an active mechanism involved," said Marvi told New Scientist , Friday (03/02/2012).

Dogs and Cats

Heart disease in dogs and cats are now beginning to be found in the veterinary practice. But practitioners are still constrained by science, medicine, and tools that hard to come by in Indonesia.

This is expressed by small animal practitioners DVM Amir Mahmud told Reuters on Sunday (03/04/2012). Drh Amir is following the National Conference of the Association of Small Animal Veterinary Practitioner Indonesia (National Conference ADHPHKI) and Small Animal Veterinary Scientific Conference, which took place from Friday (02/03/2012) in Surabaya, East Java.

Amir Mahmud DVM is the author of the Dogs Congestive Heart Failure (Congestive Heart Failure in Dogs). This book is the only book of heart disease in dogs the rise in Indonesia.

According to Amir DVM, in a scientific conference on Saturday (03.03.2012), came to light that the micro-surgery, endoscopy, ekhokardiografi, and the science of heart disease in dogs and cats are now growing in Indonesia.

The phenomenon of the Sun Day Without Shadow

Day without a shadow of the Sun will occur in some areas in Java. Solo will experience it on Thursday (01.03.2012), Semarang on Friday (2/3/3012), and Jepara on Saturday (3/3/3012). Meanwhile, Yogyakarta has experienced it on Wednesday (02/29/2012). How exactly are today without the shadow of the Sun?

In simple terms, the phenomenon can be explained by experiments at the Sun. You do this by enforcing a stick on a flat surface or sun exposed terrain and then observe its shadow.

On observations on normal days, when the early morning, the shadow will fall on the west, while the afternoon will fall to the east. At noon, the sun was directly overhead so that the shadow is very short.

Three Artifacts Found in Pagar Alam Back

rack of ancient relics (artifacts), probably derived from the megalithic era, was discovered by residents Pagar Alam, South Sumatra, Sunday (4/3/3012). Up to now, has not expressed by certain types of artifacts found. Identification is still needed.

Information from local residents mentioned that the city and surrounding region known as Besemah with a lot of ancient relics.

It is a concern of researchers to trace the history of archeology and remember to this day still no reports of new findings that heritage is priceless.

Generally, these relics are still to be investigated and treated properly in order not damaged or stolen as a result of ignorance of citizens and local government indifference.

Mars Shines Bright

Tonight is the best night to see Mars. The red planet will appear bright and can be seen without a telescope. Apparent brightness of Mars this evening related to the process of revolution around the Sun, Mars is sometimes brought to the closest point to another planet.

On Saturday (3/3/3012) ago, Mars reaches opposition with the Earth. Mars opposition means the condition in which Mars is between the Sun and the Earth, much like the condition of the eclipse of the Moon.

Logically, if the opposition occurred on Saturday, then Mars will also be at the point nearest the Earth on the same day. But because of differences in the new orbit is the closest point reached on Monday (03/05/2012) or tonight.

Tonight, Mars will be at a distance of 100.7 million kilometers from Earth. Mars never reach the closest distance to Earth for 60,000 years in opposition events in 2003.

At this time the opposition, Mars will be visible in the constellation Leo. Planets are thought to store water under the surface will still appear bright in the sky of the city. So, certainly can be seen from Jakarta.

Blind Creatures Found in Deepest Cave

Species of arthropods (animals with jointed legs) are found in cave-Voronja Krubera, the deepest cave on Earth. Depth of the cave is located near the Black Sea that reaches 2191 meters from the mouth of his cave.

One of the new species is Plutomorus ortobalaganensis found at a depth of 1980 meters. Meanwhile, three other species is Anurida stereoodorata, Deuteraphorura kruberaensis, and Schaefferia profundissima.

All species are categorized as springtails, primitive insects without wings. Living in a completely dark environment, all beings are blind. Blindness in the species A. stereoodorata compensated by chemical receptors sensitive.

Creatures eating the mushrooms and biodegradable material that was discovered by Ana Sofia Reboilera from the University of Aveiro in Portugal, and Alberto Sendra of the Valencia Museum of Natural History in Spain. They explore the cave in 2010.

Prior to this discovery, the deepest land creatures ever discovered is Ongulonychiurus colpus (depth of 550 meters in the cave area of ​​Spain) and Tritomurus Veles (430 km depth in the cave area of ​​Croatia)

The discovery of this species suggests that creature life can exist in extreme environments, with no light and little oxygen. The findings were published in the journal Terrestrial Arthropod Reviews recently.

New Kind of like a leaf-nosed bat

Scientists from the Vietnam Academy of Science and Technology in Hanoi, Vu Dinh Thong, discover new species of bat, later named Griffin Hipposideros griffini or bats.

Bat specimens were found in Chu Mom Ray National Park in Vietnam in 2008. Bats have the leaves on the nose, which in essence is a feature that serves to support echolocation.

Initially, Vu Dinh had thought that the species is a leaf nose bats are already known. However, further research proved that the different bat species.

"When arrested, bat the same size, such as the bat's nose leaf, reacted strongly. But, bats Griffin reacts quite soft," said Vu Dinh told National Geographic site on Friday (02/24/2012).

Vu Dinh and his team analyzed the resulting sound Griffin bat and take the network to perform genetik.Hasil analysis showed that the frequency of sound produced by Griffin bat is different from other leaf-nosed bats. Genetic analysis also showed that Griffin is a new species of bat.

So far, not much is known about bat Griffin. These animals are also known to exist only on the two national parks in Vietnam although other habitats might be known later.

"The findings show that Vietnam is home to a variety of bats and some of them have not been found," said Vu Dinh.
