A fifth giant planet was kicked out of the early solar system, according to computer simulations by a US-based planetary scientist. The sacrifice of this gas giant paved the way for the stable configuration of planets seen today, says David Nesvorný, who believes that the expulsion prevented Jupiter from migrating inwards and scattering the Earth and its fellow inner planets.

First video footage of a giant squid about to released

Giant sun mirrors were installed to light up one Norwegian town in winter, just to improve the mood of its residents! 

An hypothesis for explaining missing shoreline traces of ancient water ocean on mars: Some 3.4 billion years ago, giant meteoroids slammed into a frigid ocean covering Mars's northern hemisphere. The impacts kicked up enormous waves that raced across the water and swamped the shoreline, research suggests. On the scale of planetary catastrophes, such tsunamis would have dwarfed most Earthly ones.

Bad Astronomy's take on the subject: http://blogs.discovermagazine.com/badastronomy/2011/02/14/no-theres-no-proof-of-a-giant-planet-in-the-outer-solar-system/

well, he kind-of falls into his own trap: confusing/discussing "evidence" with "likelihood", and "there is" with "it may". He should have made more efforts in his writing, what he says is a bit pointless! (just put the Icarus' paper)

Interesting, but obviously something is wrong. How the big giants can remain still if the inner planets and the sun vanish at the same time !

This is a video about a giant ant colony and the 3D structure of the nest. Amazing footage about one of a superorganism.

Nice! How much dark matter still left to find?

Two aerospace companies are teaming up to launch giant space habitats to orbit, with the first such liftoff targeted for 2020. Bigelow Aerospace will loft its giant, expandable B330 modules - each of which will provide one-third as much usable volume as the entire International Space Station (ISS) - aboard United Launch Alliance (ULA) Atlas V rockets, representatives from both companies announced today (April 11).

Powered by solar energy, Thales Alenia's Stratobus has an operation lifespan of five-years and only needs ground maintenance just a few days a year Can hover 12.4 miles (20km) in the air and reaches altitudes of 20,000 meters.

After graphene and blue brain, the European Commission has quietly announced plans to launch a €1-billion Euro project to boost a raft of quantum technologies - from secure communication networks to ultra-precise gravity sensors and clocks.

Lasers + diamonds --> simulate pressure of thousands of atmospheres on planetary cores!

As a side note, this is also being used as method to create a hypothetical substance called 'metallic hydrogen'. At such high pressures, hydrogen itself should become superconducting at room temperature and thus of tremendous interest...

Planetary migration poses a serious challenge to theories of planet formation...When multiple planets stir the disk, our simulations yield the new result that large-scale migration ceases. Thus, growing planets do not migrate through planetesimal disks....Although migration through a gaseous disk is an important issue for the formation of gas giants, we conclude that migration has little impact on the formation of terrestrial planets.

It's an article from April, now that we got Anreij's Google thing though is more actual - Unusually, the search giant designs its own servers. For the first time, Google unveils one publicly, showing a surprise built-in battery. Read this blog post by Stephen Shankland on Business Tech.
