How the Moon rules your life

At last, scientists claim to have found a link between our satellite and human behaviour - like how it governs the size of your dinner

Comment: Kind of gives a new meaning to the idea of humanity being "food for the Moon", doesn't it?

Deciphering of earliest Semitic text reveals talk of snakes and spells

A 5,000-year-old Semitic text dealing with magical spells and snakes has been deciphered from an ancient Egyptian pyramid inscription, the Hebrew University of Jerusalem announced Monday.

The texts, which were first discovered a century ago in a 24th Century BCE Egyptian pyramid, are the earliest continuous Semitic texts ever to have been deciphered, said Semitic languages Prof. Richard Steiner of New York's Yeshiva University in a premiere presentation at the Hebrew University.

The passages, serpent spells written in hieroglyphic characters, are estimated to have been written between the 25th to the 30th centuries BCE.

World's worst sound? Take baked beans, a bucket and Saturday night

A year-long quest to identify the worst sound in the world ended yesterday with top honours going to the backdrop of market town Britain on a Saturday night: a person vomiting. The sound, recreated for acoustics experts by an actor with a bucket of diluted baked beans, won out over fingers being dragged down a blackboard, a dentist's drill and wailing babies in an online study that attracted 1.1m votes from around the world.

Microphone feedback, crying babies and the scrapes and squeaks of a train on a track ranked second and joint third, with a cat howling and mobile phone ringtones coming joint 12th and snoring an unexpectedly low 26th.

Moon astronauts face X-ray danger

Future lunar astronauts could be harmed by X-ray outbursts from the Sun that occur without warning and can deliver dangerous doses of radiation in just a few minutes, a new study says. The researchers suggest that lunar rovers be equipped with metal shields that astronauts could duck behind during such events.

NASA has long recognised that protons and other particles spewed out by solar flares pose a threat to astronaut safety, but particles are relatively easy to block with layers of polyethylene.

Pollution destroying pre-Aztec Mexican ruins

Oil refineries and power stations pumping acid air pollutants along Mexico's Gulf coast threaten to erase carved stone murals at the pre-Aztec ruined city of El Tajin, a scientist said on Sunday.

Air pollution specialist Humberto Bravo said acid levels in the air around El Tajin, in oil producing Veracruz state, were among the highest in Mexico.

El Tajin's architecture is famous for intricate reliefs, many depicting an ancient Mesoamerican ball game sometimes compared to basketball.

Web Site Tracks a History Of Presidential Buzzwords

In President Bush's State of the Union address Tuesday night, odds are he will make reference to insurgents, perhaps more than once.

President Bush, though, would be only the latest U.S. chief to give the word major airtime. In his 1861 State of the Union, President Lincoln decried "insurgents in open rebellion to loyal citizens who are even now making great sacrifices," a line that could be borrowed for tomorrow night's address.

Plenty more interesting observations can be made by following the evolution of major presidential speeches, and you don't need to be a history buff to come up with your own.

Zooming To Pluto, New Horizons Spacecraft Approaches Jupiter

Just a year after it was dispatched on the first mission to Pluto and the Kuiper Belt, the APL-built New Horizons spacecraft is on the doorstep of the solar system's largest planet - about to swing past Jupiter and pick up even more speed on its voyage toward the unexplored regions of the planetary frontier.

Jupiter's volcanic moon Io is to the right; the planet's Great Red Spot is also visible. The image was one of 11 taken during the Jan. 8 approach sequence, which signaled the opening of the New Horizons Jupiter encounter.

Ghost team stakes out spooky pub

GHOST hunters are trying to unravel the secrets of haunted Swindon.

Dave Wood and his team of paranormal investigators visited the Jolly Tar pub in Hannington on Sunday to try and find an explanation behind some mysterious sightings.

Dave said: "Two unusual figures have been reported in the public bar, who looked out of place. One, a man, was seen walking out of the fireplace in the main bar. Another figure, a lady was seen, and then not seen a split second later.

Let's use robots to kill people!

A new robot is heading to Iraq this spring which can accurately pinpoint the location of a gun being fired within seconds.

Robot Enhanced Detection Outpost with Lasers (RedOwl) uses sound sensors originally developed for hearing aids, advanced video sensors and neural network programming to back-trace shots to their source.
