The new research suggests the Moon possesses a solid, iron-rich inner core with a radius of nearly 150 miles and a fluid, primarily liquid-iron outer core with a radius of roughly 205 miles. Where it differs from Earth is a partially molten bound
But the data presented at the Brussels meeting made it clear that something strange was happening: the therapeutic power of the drugs appeared to be steadily waning. A recent study showed an effect that was less than half of that documented in the fi
The glory of the Roman Empire and its tragic demise was silently chronicled—and recorded—by trees. This surprising fact came to light after an extensive study of tree growth rings revealed a link between sudden climate shifts and the rise and fall of
Previous efforts in the 1990s to recover nuclei in cells from the skin and muscle tissue from mammoths found in the Siberian permafrost failed because they had been too badly damaged by the extreme cold.
Researchers have been working for more than a decade towards bringing the long extinct woolly mammoth back to life. The Japanese have been at the forefront in the project to return woolly mammoths to the land of the living. It's been a dream borderi
Thunderstorms are known to create tremendously high electric fields - evidenced by lightning strikes. Electrons in storm regions are accelerated by the fields, reaching speeds near that of light and emitting high-energy light rays - gamma rays - a
ahul is the name given to the single Pleistocene-era continent which combined Australia with New Guinea and Tasmania. At the time, the sea level was as much as 150 meters lower than it is today; and it was separated from the other great land mass (Su
Disintegrating: A newly-discovered species of rust-eating bacteria will have consumed the Titanic on the bed of the North Atlantic within 20 years Identified using DNA technology, the bacteria and has been found on clumps of rust - known as rust
n a paper published recently in Geology, Mark Johnson and co-authors present another surprise: nice fresh drumlins. Múlajökull is an outlet glacier, draining one of the ice caps in Iceland. Like almost every other glacier, it has been retreating. Lik
The north magnetic pole (NMP), also known as the dip pole, is the point on Earth where the planet's magnetic field points straight down into the ground. Scottish explorer James Clark Ross first located the NMP in 1831 on the Boothia Peninsula in wha
The North Magnetic Pole should not be confused with the Geographic North Pole, nor with the lesser known North Geomagnetic Pole
Large numbers of dead birds were also found in Kentucky around Christmas and more were found in the following days. Earlier this week, tens of thousands of small fish were found washed up in the Chesapeake Bay area. Despite their deaths being bla
For more than three centuries inventors—usually crackpots—have sought the elusive fantasy of a perpetual motion machine. Now investigators of an amazing object stuck in the dusty corners of an obscure Romanian museum may have found the next best thin
The egg was laid by an elephant bird, which were more than 10 feet tall and weighed around half a ton, but what caused the huge birds to die out has remained a mystery, with some claiming they were hunted to extinction by humans and others blaming cl
Now that holy grail is a step closer after scientists employed by the ruler of Abu Dhabi claim to have generated a series of downpours. Fifty rainstorms were created last year in the state's eastern Al Ain region using technology designed to cont
The sun is waking up from a deep slumber, and in the next few years we expect to see much higher levels of solar activity. At the same time, our technological society has developed an unprecedented sensitivity to solar storms. The intersection of the
Released in December, the image is among a series of new views snapped by MRO's HiRISE camera that show intriguing geological features on Mars. Each image covers a strip of Martian ground 3.7 miles (6 kilometers) wide and can reveal a detail about a
The NSF announced this week that the final detectors have been installed and Ice Cube is officially complete. I visited last January as they were well underway. Neutrinos are the smallest thing you cannot imagine. They are the tiniest wisp of noth
have repeatedly pointed out that BP and the government applied massive amounts of dispersant to the Gulf Oil Spill in an effort to sink and hide the oil. Many others said the same thing.
Can something be in two places at once? Can something be in two separate states at once? According to Einstein and the weird Twilight Zone rules of the quantum world the answer has always been a definite maybe. The math supported the concept and scie
ur view of the early Universe may be full of mysterious circles — and even triangles — but that doesn't mean we're seeing evidence of events that took place before the Big Bang. So says a trio of papers taking aim at a recent claim that concentric
Something that many anthropologists speculated over for decades has been proven: a third species of human has been confirmed. The confirmation came after extensive DNA testing of a 30,000 year old fossil. The discovery of a third type of human proves
Over the past decades, there have dozens of articles in the media describing dire futures for coral reefs. In the 1960s and '70s, we were informed that many reefs were being consumed by a voracious coral predator, the crown-of-thorns starfish. In th
An entirely new type of physics is being played out—literally before our eyes and ears. The physics of time (and its relationship to space and the quantum reality) may be better understood by determining the underlying nature of the auditory and visu
Professor Ralph Keeling of Scripps Institute is worried. In fact, he's very worried. According to the data Keeling has meticulously collected since 1989 the world is running out of breathable air—and the rate that it's losing oxygen is now on the v

An accurate ionization lifetime is critical to understanding the amount of carbon released from comets, said Jeff Morgenthaler, senior scientist at PSI. A shorter lifetime suggests that the carbon content of some comets may be lower than previousl
The extremely-rare lunar eclipse which coincided with 2010's winter solstice for the first time in over 400 years happened just a few hours ago. NASA claims the last time these astronomical events took place at the same time was on Dec. 21, 1638,
According to Frank Fenner, emeritus professor of microbiology at the Australian National University, you won't live to see 2100—even if you're still in excellent health. In fact, no one else will be around to ring in the New Year 90 years from now
The sun is worrying scientists. They've been quietly asking each other what's wrong with it. They've been asking that question for some time. Now their question's about to be answered. The giant is about to awaken from its abnormal slumber and sc
