Surviving a Zombie Apocalypse: Just Do the Math

This equation could spell your doom: (bN)(S/N)Z = bSZ. That is, if you ever found yourself in the midst of a zombie pandemic.

That's because the calculation describes the rate of zombie transmission, from one walking dead individual to many, according to its creators, Robert J. Smith?, a mathematics professor at the University of Ottawa who spells his name with a "?" at the end, and his students.

Big Bang Light Reveals Minimum Lifetime of Photons

The notion of the speed of light as the cosmic speed limit is based on the assumption that particles of light, called photons, have no mass. But astrophysical observations cannot rule out the slim chance that photons do have a tiny bit of mass—a prospect with wide ramifications in physics. For instance, if photons weigh nothing at all, they would be completely stable and could theoretically last forever. But if they do have a little mass, they could eventually decay into lighter particles. 

SpaceX wins bid to launch Canadian radar satellites

Privately owned Space Exploration Technologies was selected to launch a trio of Canadian radar satellites aboard a single Falcon 9 rocket, the company announced on Tuesday.

So when Wallflower Architecture and Design began to create Wind Vault House in the island nation, the company has established an elaborate system of passive cooling.
A bit like a store Wind Vault House to be honest, so far very attractive building. 

Astronomers are digging under the brown dwarfs

Astronomers have focused all their attention on brown dwarfs, trying to uncover all of their secrets. Despite the fact that brown dwarfs are not the full-fledged stars, and substars and occupy an intermediate niche between these massive stars and planets, they cause enormous interest among scientists. Astronomers from around the world are trying to figure out what is more like brown dwarfs: the planets or stars. What a performance they made more or are they still are an entirely different stage of development than the traditional brown dwarfs and planets. In addition, the astronomers looking for protoplanetary disks around brown dwarfs, and the worlds that are formed in these disks.

Hubble Space Telescope photographed a few nearby galaxies

This galaxy is like a giant funnel that sucks in everything that falls into it. According to the scientists, "Whirlpool" - is a classic spiral galaxy diameter of 100 thousand light-years. It is a favorite subject of Earth observation from amateur astronomers, since it has contrasting branches, because of which it is perfectly visible through a telescope.

Hubble has also managed to remove the flash bright star in the galaxy M59 (pictured below).

Super-dense neutron stars and their secrets

Scientists have new clue to the strange operation of neutron stars - these objects are so dense that they compress the mass of several suns in the space of less than a terrestrial city.

Neutron stars are born when a massive star runs out of fuel for nuclear fusion and decay. They cast off its outer layers, and their nuclei are compressed by gravity and become denser and denser.

Mayan Discovery: Ancient Monument Reveals Royal Struggle

A nearly 1,500-year-old Mayan stone monument, inscribed with a story of an ancient power struggle, has been unearthed in Guatemala.

The stone slab, which dates to A.D. 564, was found in a small tunnel that adjoins the tomb of an ancient queen beneath the Mayan temple at the site of El Peru-Waka'.

NASA wants to exceed the speed of light

Nobody is surprised that NASA wishes to exceed the speed of light, which to our knowledge is the fastest in the universe. Most potentially habitable planets found the U.S. space agency are several light years away, meaning that for many years we would need to travel at the speed of light to reach them. This is no doubt a problem, because currently we are not able to achieve even a tenth of the speed of light, although the agency supergeniuses already working on it.

Physicist Harold G. White hopes to use speed travel "warp" (or push warp ) to exceed the speed of light.

Why does the universe have fewer dwarf galaxies which should?

Turn and shoot the Question: "What about the sun?". "He went to sleep," his mother answered thinking an explanation that satisfies the curiosity of his three years. "He night," says halfway between the statement and the question and question again looking at the sky: "What about the moon? In these sentences, little seems to sum up, with its childlike simplicity-the concerns, from primitive man to the present day, led mankind to observe the sky for answers to many questions.

Probe NASA image of Earth is 1.5 billion km

NASA released the first images of the Earth from untreated about 1.5 billion kilometers. The record was made by the Cassini spacecraft, orbiting Saturn, and will make part of a mosaic that shows the giant planet and our planet.

Mars suffered early loss of most of the atmosphere

When I was a young man with less than 500 million years ago, Mars suffered a catastrophe that hung its magnetic field, leave it exposed to strong solar winds and caused him to lose most of its atmosphere. This is the most plausible story for children on the planet, according to the latest findings of the rover Curiosity.

The conclusion is in two studies published today in the journal "Science" that reveal with unprecedented precision the composition of air on Mars.

A study warns that sea level may rise 20 meters by the end of the century

The ice of the Antarctic "is much more sensitive" to climate changes than estimated, according to a scientific study which says that sea level could rise 20 meters to the end of the century if this area, the West Antarctic and Greenland, were to melt as in the Pliocene.

These are two of the findings of an international study published in the journal Nature Geo science, led by researchers from Imperial College London and Spanish participation.

Chemically induced pluripotent stem cells

Scientists have been able to reprogram the mature human stem cells, using only the chemical compound (without genetic manipulation).

A new method of obtaining cells are as versatile as embryonic stem cells, reduces the risk of developing cancer or of mutations that can occur as a result of stem cell therapies, "reprogrammed" with the introduction of additional genes.

Since then, in 2006, it was announced the discovery of induced pluripotent stem cells ( iPSCs ), scientists have sought to reduce the number of additional genes required for such cells. But it is always required at least one encoding a protein Oct-4 .

Fourth domain for a new form of life

The famous anecdote "On board the space station discovered a giant virus that infected Soviet cosmonaut" may be not so absurd: Biologists have discovered a virus of such size that they have no right to believe in it.

Initially called it simply - NLF, a new form of life (New Life Form). Strange body, a dedicated French microbiologist from sea water samples, pick up off the coast of Chile, infects the simplest - amoebas. Soon, the same body showed up and in Australia.
