Moon Illusion

Presented another answer to the age old question of why the moon comes into view larger close to the horizon than at the pinnacle.

Joseph Antonides and Toshiro Kubota from Susquehanna University (USA) re-opened the debate around the famous optical illusion. According to their theory, the illusion is due to inconsistency between the estimates of distances, which allow the brain is subjective picture of the world and according to binocular vision.

First time Martian rock drilling ready

Curiosity rover is get ready to hold the first Martian rock drilling - in a carefully selected for this purpose, which in the history have to splash water.

Extraordinary ton machine should start work in the next couple of weeks. 

Reprogramming Leprosy

Investigating the mechanisms of spread of leprosy (leprosy) in the body, scientists have noticed that its agents - bacteria Mycobacterium lepta - can exchange mature cells into stem cells (which can develop into different cell types).

Researchers have identified lemmotsity mice and infected them with agents of leprosy. 

Astronomers have exposed the largest structures in the universe

A group of British astronomers exposed the largest known structures in the universe. This is a group linked by a single gravitational field of active galactic nuclei, which make bigger from one end to 4 billion light years away. Scientifically verbal communication, the structure is a large group of quasars.

ALMA makes gas flows visible on the planet formation

Astronomers using the Atacama Large Millimeter / submillimeter Array (ALMA) for the first time to directly observe how extensive gas streams overcome a gap in the disk of matter around a young star. In theory, should such gas streams arise during the growth phase of planets? This is a key stage in the birth of the gas giants. The observations are the second January 2013 published in the journal Nature.

New View of the globular cluster 47 Tucanae

Globular clusters 47 Tucanae are huge spherical cloud of old stars held together by gravity. They are turning around the cores of galaxies, and satellites orbiting Earth. These groups of stars contain very little gas and dust - it is believed that most of the cluster has been driven by winds and explosions of stars it contains, or has been torn by the interstellar gas has been interacting with the cluster. Any remaining material coalesced into stars billions of years ago.

Reverse Effect: Eruption of climate

The eruption can cause climate change, no doubt. Supervolcanoes that send to the stratosphere many tons of ash may affect the global climate. But it appears that perhaps the reverse effect: the German and American scientists have found evidence that climate can change the activity of volcanoes.

This is something new! However, researchers at Harvard University in collaboration with the center GEOMAR know what they say on their side - the results of the analysis of volcanic deposits in the last million years.
