A Mexican man has discovered dozens of dinosaur footprints dating back up to 110 million years along the banks of a dried river, scientists said on Tuesday.
Biologist Oscar Polaco said the footprints, found by a local resident in a desert region in central Mexico, belonged to three prehistoric species that came to drink water in the area, once a swampy zone close to the sea.
Polaco said more studies needed to be done to determine what species of dinosaur the fossilized prints, each one up to 60 cm (24 inches) across, belonged to.

One of anthropology's most enduring mysteries - the origins of the ancient Etruscan civilisation - may finally have been solved, with a study of cattle.
This culturally distinct and technologically advanced civilisation inhabited central Italy from about the 8th century BC, until it was assimilated into Roman culture around the end of the 4th century BC.
The origins of the Etruscans, with their own non-Indo-European language, have been debated by archaeologists, geneticists and linguists for centuries. Writing in the 5th century BC, the Ancient Greek historian Herodotus claimed that the Etruscans had arrived in Italy from Lydia, now called Anatolia in modern-day Turkey.

The Octagon Earthworks in Newark is one remnant of the Newark Earthworks, recently listed by The Dispatch as one of the Seven Wonders of Ohio.
Earlham College professors Ray Hively and Robert Horn demonstrated in 1982 that the walls of this 2,000-yearold circle and octagon were aligned to the points on the horizon, marking the limits of the rising and setting of the moon during an 18.6-year cycle.

The blood of the largest bat in Europe reveals it can devour birds in midair at night, the only animal known to do so thus far, evidence now strongly suggests.
Roughly five billion songbirds migrate across the Mediterranean Sea every year, mainly at night. Although more than 90 percent of these birds weigh on average less than 20 grams (0.7 ounces), this could amount to about 100,000 metric tons of food upon which predators might wish to dine. (A metric ton is equivalent to 2,204 pounds).
No animal, however, was known to hunt the birds while they flew at night. Falcons catch migratory birds along the Mediterranean only during the day, while owls and some tropical bats capture vertebrate prey on or near the ground or other surfaces at night.

A laboratory set up at Princeton University, N.J., to study ESP and telekinesis will close this month, ending an awkward 30-year relationship with the scientific world. Princeton Engineering Anomalies Research lab (PEAR) was set up in 1979 to examine how the human mind can affect computers and machines.
Founder Robert Jahn, 76, said the lab, despite ageing equipment and dwindling finances and the ridicule of the scientific community, did what it needed to, showing statistically significant results. Jahn, former dean of Princeton's engineering school and an emeritus professor, told the New York Times, 'For 28 years, we've done what we wanted to do, and there's no reason to stay and generate more of the same data. If people don't believe us after all the results we've produced, then they never will,' BBC Online reported Tuesday.

Whales possess a form of communication that allows them to signal other whales hundreds of miles away. Some experts say it is indeed a form of telepathy. Does human telepathy exist? Is there scientific evidence for this particular form of extra-sensory perception (ESP)?
Certainly if human telepathy existed we could explain many weird human experiences. Telepathy would account for, according to a recent newspaper account, a mother "saw" her daughter miles away roll her car over in a traffic accident and "saw" her daughter injured and trapped within the wreckage. It would explain the Australian woman who "felt" her mother die suddenly at the precise moment she passed away half way around the world in London. Telepathy would explain many strange little happenings such as these, or even something that is very common: we hear the telephone ring and we know who's ringing before we pick up the phone.

A chip with 80 processing cores and capable of more than a trillion calculations per second (teraflop) has been unveiled by Intel.
The Teraflop chip is not a commercial release but could point the way to more powerful processors, said the firm.
The chip achieves performance on a piece of silicon no bigger than a fingernail that 11 years ago required a machine with 10,000 chips inside it.

Online encyclopaedia Wikipedia might have to close because it only has enough funding for another four months.
Florence Devouard, chairwoman of the Wikimedia Foundation, told the Lift07 conference that the outfit might join the Everywhere Girl and disappear from the Interweb.
Wikipedia normally raises a $1 million a year, this year it has raised $1.1 million. But it claims that it needs $5 million a year to sustain operations.

A new study published in the journal Science bills Enceladus as "a cosmic graffiti artist, caught in the act."
Last spring NASA's Cassini spacecraft showed what appeared to be geysers streaming out from Enceladus's surface.
One theory suggests that the plumes are created by liquid water below the surface that freezes instantly in the moon's frigid surface climate.
"Enceladus coats itself, snows on itself, and distributes pure water ice particles on its surface," said lead study author Anne Verbiscer, an astronomer at the University of Virginia.
