A razão pela qual o Universo existe, apesar de, quando a Matéria e a Antimatéria colidem, aniquilam-se mútuamente:

Yahoo! Canada NewsPhysicists have long wondered why the universe exists when matter and anti-matter particles obliterate each other on contact.

But new data from a particle accelerator in the United States suggests a reason.

The tests showed that when anti-protons and protons collide, the resulting new particles show a one per cent skew toward matter over anti-matter. Over a long period of time, this characteristic of the universe could explain why matter has come to dominate over anti-matter.

...Arrepiante, o Hubble observa uma estrela a consumir um Planeta:

Six hundred light-years from Earth, a huge exoplanet circling close to its home star is slowly, inexorably being devoured.

WASP 12B orbits just 2 million miles from its star, which means the surface of the planet reaches temperatures over 2,800 Fahrenheit. The sun’s gravitational pull is stronger on the front surface of the planet than on the back, so the planet has been pulled into a football shape. If you were floating on the gaseous planet, and looking heavenward, the sun would take up nearly the entire sky.

Os nossos Antepassados, os Peixes...

 

Humans have hardy prehistoric fish ancestors to thank for paving the way to their eventual evolution, a new study suggests.

About 360 million years ago a mass extinction event hit the reset button on Earth's life, wiping out most of the fish that existed then near the time when the first vertebrates (all animals with backbones) crawled from water towards land. The species fortunate enough to survive set the stage for modern vertebrate biodiversity.

Encontrados Fósseis de Invertebrados, muito raro:

A discovery of a huge number of soft-bodied marine animal fossils is giving these critters a fair shake in the fossil record.

Paleontologists found more than 1,500 soft-bodied marine animal fossils, some dating to nearly 500 million years ago. The discovery provides a more complete understanding of marine life at that time and suggests that these soft-bodied sea animals did not die off during a major extinction event during the Cambrian period, as previously thought.

...E para acabar em beleza, um Metamaterial que vai permitir a criação de Câmaras que vêem ATRAVÉS das paredes, detectar tumores, e ainda... Compostos Químicos, SEM abrir os contentores desses Compostos!

A new class of man-made materials could hold the key to creating X-ray-like cameras that can see through walls and clothing.

Called metamaterials, these substances could harness terahertz radiation, light with energies between infrared waves and microwaves. Terahertz waves are essentially low-level heat created by the movement of molecules. They’re largely unexplored as a regime of energy because they are very difficult to detect, but if harnessed could lead to devices with some remarkable abilities.

“Terahertz can do things like see through cardboard, styrofoam, or clothes, which is unique compared to infrared, visible, or microwave,” researcher Richard Averitt told Livescience.com.

Mysterious radio waves emitted from nearby galaxy

* 13:13 14 April 2010 by Stephen Battersby, Glasgow

There is something strange in the cosmic neighbourhood. An unknown object in the nearby galaxy M82 has started sending out radio waves, and the emission does not look like anything seen anywhere in the universe before.


"We don't know what it is," says co-discoverer Tom Muxlow of Jodrell Bank Centre for Astrophysics near Macclesfield, UK.


The thing appeared in May last year, while Muxlow and his colleagues were monitoring an unrelated stellar explosion in M82 using the MERLIN network of radio telescopes in the UK. A bright spot of radio emission emerged over only a few days, quite rapidly in astronomical terms. Since then it has done very little except baffle astrophysicists.


It certainly does not fit the pattern of radio emissions from supernovae: they usually get brighter over a few weeks and then fade away over months, with the spectrum of the radiation changing all the while. The new source has hardly changed in brightness over the course of a year, and its spectrum is steady.

Vatican Official Declares Extraterrestrial Contact Is Real
by Richard Boylan, Ph.D
Monsignor Corrado Balducci, a theologian member of the Vatican Curia (governing body), and an insider close to the Pope, has gone on Italian national television five times, including recent months, to proclaim that extraterrestrial contact is a real phenomenon. Balducci provided an analysis of extraterrestrials that he feels is consistent with the Catholic Church's understanding of theology. Monsignor Balducci emphasizes that extraterrestrial encounters "are NOT demonic, they are NOT due to psychological impairment, they are NOT a case of entity attachment, but these encounters deserve to be studied carefully." Since Monsignor Balducci is a demonology expert and consultant to the Vatican , and since the Catholic Church has historically demonized many new phenomena that were poorly understood, his stating that the Church does not censure these encounters is all the more remarkable.
Balducci revealed to a visiting American professional that the Vatican is closely following this phenomenon quietly. My informant originally surmised that the Vatican is receiving much information about extraterrestrials and their contacts with humans from its Nunciatures (embassies) in various countries. But subsequent information indicated that the Monsignor has gotten his cases from other sources. Monsignor Balducci is a member of a group which acts as consultants to the Vatican on various matters concerning humans in possible contact with supernatural beings. As such, the matter of extraterrestrial encounters would fall within their purview, and possibly as well the spiritual significance of the emerging general realization of extraterrestrial contact.
Parallel information from National Security Council scientist Dr. Michael Wolf , a member of the NSC's SSG subcommittee for managing the UFO phenomenon, as well as from noted author and Vatican expert Father Malachi Martin, suggests that the Vatican is concerned that it will have a major doctrinal updating situation on its hands when extraterrestrial contact becomes authoritatively announced by world governments over the next several years.
