The row of nine stones on Cut Hill was discovered in 2004 on one of the highest, most remote hills of Dartmoor national park. "It is on easily the most spectacular hill on north Dartmoor," says Andrew Fleming, president of the Devon Archaeological Society. "If you were looking for a distant shrine in the centre of the north moor, that's where you would put it."
Ralph Fyfe of the University of Plymouth and independent archaeologist Tom Greeves have now carbon-dated the peat surrounding the stones. This suggests that at least one of the stones had fallen - or been placed flat on the ground - by between 3600 and 3440 BC, and another by 3350 to 3100 BC (Antiquity, vol 84, p 55).
That comes as a surprise to archaeologists, who, on the strength of artefacts found nearby, had assumed that Dartmoor monuments like Cut Hill and Stall Moor (pictured) dated from the Bronze Age, around 2100 to 1600 BC. Instead, Fyfe suggests that Cut Hill is from the Neolithic period, the same period that Stonehenge was built.
The New York anthropology professor said the subject should be part of the mainstream as a serious "area of study".
The Niagara County Community College, a state university in New York, lecturer said due to the high amount of sightings every year, it should follow that students should be able to investigate phenomenon.
"(A sighting) happens to millions of people (around the world)," he said.
"It's about time we looked into this as a worthy area of study.
"It's important that the whole subject be brought out in the open and investigated."
Prof Haseley, who is also head of the Western New York Mutual UFO Network, an organisation that is focused on UFO research, said there were up to 50 UFO sightings are reported every month across region.

A lightning researcher at the University of Bath has discovered that during thunderstorms, giant natural particle accelerators can form 40 km above the surface of the Earth. On Wednesday 14th April Dr. Martin Fullekrug will present his new work at the RAS National Astronomy Meeting (NAM 2010) in Glasgow. The image shows a transient airglow or 'sprite' above a thunderstorm in France in September 2009.
On April 14, Dr. Martin Fullekrug presented his new work at the RAS National Astronomy Meeting (NAM 2010) in Glasgow.
When particularly intense lightning discharges in thunderstorms coincide with high-energy particles coming in from space (cosmic rays), nature provides the right conditions to form a giant particle accelerator above the thunderclouds.
The cosmic rays strip off electrons from air molecules and these electrons are accelerated upwards by the electric field of the lightning discharge. The free electrons and the lightning electric field then make up a natural particle accelerator.
The PV cell prototyped at the Kyoto Institute of Technology by adding cobalt to a p-type GaN thin film and laminating an n-type material (right). The cell with an absorbing layer measures 10 x 10mm. The surrounding thin rectangular patterns are electrodes. And the p-type GaN thin film without cobalt (left).
The group, which is led by Saki Sonoda, associate professor at the Kyoto Institute of Technology, made the announcement March 19, 2010, at the 57th Spring Meeting of the Japan Society of Applied Physics.
The PV cell was realized by adding "3d transition metals" including manganese (Mn) to transparent composite semiconductors with a wide bandgap such as gallium nitride (GaN). It could enable to develop a highly-efficient PV cell by using a simply-joined cell without making a multi-junction cell.
Currently, the conversion efficiency of the new PV cell is low, but its open voltage (Voc) is as high as 2V.
The research group delivered a 90-minute lecture on the cell under the title "Nitride Semiconductor Added With Transition Metals as a Photoelectric Conversion Material for Ultraviolet, Visible and Infrared Lights ~ In the Aim of Realizing the Next-generation Super-efficient PV Cell With a Simple Element Structure."
"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.

Patrick Boomer, captured these photographs Southwest of Red Deer, Alberta, Canada. These comparison photos of Comet McNaught, taken on Jan. 6th, Jan. 7th and Jan 9th (2007) shows the difference a day makes. Both photos were taken at 5:36pm local time.
Instead of using the length of the comet's tail to measure the scale of the comet, astronomers used data from the ESA/NASA Ulysses spacecraft to determine the size of the region of space disturbed by the comet's presence - a cosmic wake across the solar system.
Through analysis of magnetometer data, scientists found evidence of a decayed shockwave surrounding the comet, which was created when ionized gas emitted from the comet's nucleus joined the fast-flowing particles of the solar wind. That, in turn, caused the solar wind around the comet to abruptly slow down.
Researchers believe they have found evidence of real natural disasters on which the ten plagues of Egypt, which led to Moses freeing the Israelites from slavery in the Book of Exodus in the Bible, were based.
But rather than explaining them as the wrathful act of a vengeful God, the scientists claim the plagues can be attributed to a chain of natural phenomena triggered by changes in the climate and environmental disasters that happened hundreds of miles away.
That assessment changed when Brigham Young University researchers used MRI technology to observe what happened in the brain when people viewed images of complete strangers.
If the stranger happened to be overweight and female, it surprisingly activated in women's brains an area that processes identity and self-reflection. Men did not show signs of any self-reflection in similar situations.
"These women have no history of eating disorders and project an attitude that they don't care about body image," said Mark Allen, a BYU neuroscientist. "Yet under the surface is an anxiety about getting fat and the centrality of body image to self."
Allen makes his report with grad student Tyler Owens and BYU psychology professor Diane Spangler in the May issue of the psychological journal Personality and Individual Differences.
Neuroscientists believe this "mirroring" is the mechanism by which we can "read" the minds of others and empathize with them. It's how we "feel" someone's pain, how we discern a grimace from a grin, a smirk from a smile.
Problem was, there was no proof that mirror neurons existed -- only suspicion and indirect evidence. Now, reporting in the April edition of the journal Current Biology, Dr. Itzhak Fried, a UCLA professor of neurosurgery and of psychiatry and biobehavioral sciences, Roy Mukamel, a postdoctoral fellow in Fried's lab, and their colleagues have for the first time made a direct recording of mirror neurons in the human brain.

The Rosette molecular cloud, seen by Herschel.
The Rosette Nebula resides some 5,000 light years from Earth and is associated with a larger cloud that contains enough dust and gas to make the equivalent of 10,000 Sun-like stars. The Herschel image shows half of the nebula and most of the Rosette cloud. The massive stars powering the nebula lie to the right of the image but are invisible at these wavelengths. Each colour represents a different temperature of dust, from - 263ºC (only 10ºC above absolute zero) in the red emission to - 233ºC in the blue.










Comment: The whole point is that it serves the interests of religions to ascribe to natural disasters the "wrath of God". How would they hold power over the rest of us otherwise?
