It turns out, his writings are even more valuable than we have thought.A science historian at The University of Manchester has cracked "The Plato Code" — the long disputed secret messages hidden in the great philosopher's writings.

Israel Expands Geo Intelligence Capabilities Over Iran with New Spy Satellite

Israel launched a spy satellite known as Ofek-9 into orbit that will help it more efficiently monitor the region, including Iran. The new satellite increases the speed at which Israel can receive high-resolution images of subjects of interest. The Israel Defense Ministry said that it would join two other active spy satellites in the Ofek series already orbiting the earth, and all three satellites would give Israel considerable coverage of sensitive areas. As Israel considers Iran to be a strategic threat, its expanded GEOINT efforts are aimed at gather intelligence regarding Iran’s nuclear program that Israel believes is meant for developing bombs, despite Iranian denials. In addition, it was just reported that the satellite is now working.

Six New Planets Discovered

 An international team, including Oxford University scientists, has discovered six diverse new planets, from 'shrunken-Saturns' to 'bloated hot Jupiters', as well a rare brown dwarf with 60 times the mass of Jupiter.
The six new planets are:

CoRoT-8b: the smallest in this batch: At about 70% of the size and mass of Saturn, CoRoT-8b is moderately small among the previously known transiting exoplanets. Its internal structure should be similar to that of ice giants, like Uranus and Neptune, in the Solar System. It is the smallest planet discovered by the CoRoT team so far after CoRoT-7b, the first transiting Super-Earth.

CoRoT-10b: the eccentric giant: The orbit of CoRoT-10b is so elongated that the planet passes both very close to and very far away from its star. The amount of radiation it receives from the star varies tenfold in intensity, and scientists estimate that its surface temperature may increase from 250 to 600°C, all in the space of 13 Earth-days (the length of the year on CoRoT-10b).

CoRoT-11b: the planet whose star does the twist: CoRoT-11, the host star of CoRoT-11b, rotates around its axis in 40 hours. For comparison, the Sun's rotation period is 26 days. It is particularly difficult to confirm planets around rapidly rotating stars, so this detection is a significant achievement for the CoRoT team.

CoRoT-12b, 13b and 14b: a trio of giants: These three planets all orbit close to their host star but have very different properties. Although CoRoT-13b is smaller than Jupiter, it is twice as dense. This suggests the presence of a massive rocky core inside the planet. With a radius 50% large than Jupiter's (or 16 times larger than the Earth's), CoRoT-12b belongs to the family of `bloated hot Jupiters', whose anomalously large sizes are due to the intense stellar radiation they receive. On the other hand, CoRoT-14b, which is even closer to its parent star, has a size similar to Jupiter's. It is also massive, 7.5 times the mass of Jupiter, which may explain why it is less puffed up. Such very massive and very hot planets are rare, CoRoT-14b is only the second one discovered so far.

CoRoT-15b: the brown dwarf: CoRoT-15b's mass is about 60 times that of Jupiter. This makes it incredibly dense, about 40 times more so than Jupiter. For that reason, it is classified as a brown dwarf, intermediate in nature between planets and stars. Brown dwarfs are much rarer than planets, which makes this discovery all the more exciting.

Dr. Suzanne Aigrain leads a team of UK researchers at the Universities of Oxford, Exeter and St Andrews who participate in the CoRoT exoplanet program. Their research is supported by the Science and Technology Facilities Research Council.

Five centuries of North Carolina maps digitally archived online

Over 3,200 historic maps of North Carolina are now available online as part of the Digital North Carolina Maps Project. North Carolina Maps contains more than 3,000 maps, ranging in date from the late 1500s to 2000 and including detailed maps for each of North Carolina's one hundred counties. Featuring maps from three of the state's largest map collections -- the North Carolina State Archives, the North Carolina Collection at UNC-Chapel Hill and the Outer Banks History Center. North Carolina Maps is made possible by the Institute of Museum and Library Services under the provisions of the Library Services and Technology Act as administered by the State Library of North Carolina. Nick Graham, project manager and coordinator of the North Carolina Digital Heritage Center, said that the project is already gaining widespread popularity amongst people in various levels of academia. “We've heard from K-12 teachers, students, university faculty and genealogists, all of whom are big fans of the project,” said Graham.The website also contains an interactive option, which allows users to lay selected historic maps over current street maps and satellite images.

Coffee or Tea: Enjoy Both in Moderation for Heart Benefits

Researchers in The Netherlands found:

  • Drinking more than six cups of tea per day was associated with a 36 percent lower risk of heart disease compared to those who drank less than one cup of tea per day.
  • Drinking three to six cups of tea per day was associated with a 45 percent reduced risk of death from heart disease, compared to consumption of less than one cup per day.

  • And for coffee they found:
    Coffee drinkers with a modest intake, two to four cups per day, had a 20 percent lower risk of heart disease compared to those drinking less than two cups or more than four cups.

  • Although not considered significant, moderate coffee consumption slightly reduced the risk of heart disease death and deaths from all causes.

Wetlands Loss Endangers Birds on African-Eurasian Flyway

One-third of the critical wetlands that migratory waterbirds need when traveling between Africa, the Middle East, Europe and Central Asia are entirely unprotected, according to the first survey using a new online information tool. As a result, 42 percent of these waterbird species are in decline, bird experts warn.The online tool was unveiled Monday at an International Waterbird Conservation Symposium taking place in The Hague to mark the 15th anniversary of the African-Eurasian Migratory Waterbird Agreement, AEWA. The international wildlife treaty aims to conserve migratory waterbirds which use the African-Eurasian here

Gulf oil full of methane

The oil emanating from the seafloor contains about 40 percent methane, compared with about 5 percent found in typical oil deposits, said John Kessler, a Texas A&M University oceanographer who is studying the impact of methane from the spill.

That means huge quantities of methane have entered the Gulf, scientists say, potentially suffocating marine life and creating "dead zones" where oxygen is so depleted that nothing lives.
 It is an overlooked danger in oil spill crisis: The crude gushing from the well contains vast amounts of natural gas that could pose a serious threat to the Gulf of Mexico's fragile ecosystem.

Sky Holes

Across the world, sightings of strange cloud holes have triggered amusement and speculation. One such was in October 2009 and was called the "halo over Moscow" that some called a alien spacecraft.
"Sky holes", also known more formally as "Hole Punch Clouds" or "Punch Hole Clouds", are not some secret Government experiment, nor Alien cloaked spacecraft. They are instead, holes that form in thin, puffy cloud layers.
There are many hypothesis for what causes them: jet planes passing through the cloud layer, wind, and others. But they remain an enigmatic example of complex weather processes.
One prevailing theory is that Cirrocumulus clouds contain both ice crystals, and supercooled water droplets. The introduction of the extra water from the jet exhaust causes a rapid increase in the rate of crystallization, and all the water turns to ice as the ice crystals get larger. This rapidly desaturates the air, which then pulls in moisture from the air around it, thus spreading the hole.

Star Chart

A star chart is a map of the night sky. Astronomers divide these into grids to use them more easily. They are used to identify and locate astronomical objects such as stars, constellations and galaxies. They have been used for human navigation since time immemorial. Note that a star chart differs from an astronomical catalog, which is a listing or tabulation of astronomical objects for a particular purpose. A planisphere is a type of star chart.

A planisphere is a star chart analog computing instrument in the form of two adjustable disks that rotate on a common pivot. It can be adjusted to display the visible stars for any time and date. It is an instrument to assist in learning how to recognize stars and constellations. The astrolabe, an instrument that has its origins in the Hellenistic civilization, is a predecessor of the modern planisphere.

10 Ways Science is Using Human-Animal Hybrids

In Greek mythology, chimeras were vicious monsters feared by many. This fire-breathing animal had the head and body of a lioness, with a goat head protruding from her back and the tail of a snake. Today, “chimera” refers to an animal that has two or more different sets of genetically distinct cells working together. Remember the mouse with the ear on its back?

The movie "Splice" showcases a chimera experiment gone horribly wrong: scientists create a human-animal hybrid that becomes evil and goes completely out of control.

While the movie is obviously science fiction, chimera experiments with human cells are not, and real life scientists have been conducting them for decades. We take a look at a few that have been successful in the past and how they’re advancing medicine.
