Magnetic fields and specialized "antenna" elements that respond to them have existed since planet Earth locked into orbit, and those responsive elements are perturbed or disturbed by solar activity and lightning in a daily activity called the Schumann Resonance. In combination, these systems are the natural balance of things that oversee the evolution of all life on earth by providing information to control and power cell assembly and the functions of life.
It is only a breathless Hollywood script: treasure-hunter Indiana Jones races with German archaeologists to track down the fabled Ark of the Covenant, the chest that held the stone tablets on which the Ten Commandments were etched.
Now German researchers claim to have found the remains of the palace of the Queen of Sheba - and an altar that may have held the Ark.
The discovery, announced by the University of Hamburg, has stirred sceptical rumblings from the archaelogical community. The location of the Ark, indeed its existence, has been a source of controversy for centuries.
Regarded as the most precious treasure of ancient Judaism, it is at the heart of a debate about whether archaeology should chronicle the rise and fall of civilisations or explore the boundaries between myth and ancient history.

Inca surgeons in ancient Peru commonly and successfully removed small portions of patients' skulls to treat head injuries, according to a new study.
The surgical procedure-known as trepanation-was most often performed on adult men, likely to treat injuries suffered during combat, researchers say.
A similar procedure is performed today to relieve pressure caused by fluid buildup following severe head trauma.
Around the ancient Inca capital of Cuzco, remains dating back to A.D. 1000 show that surgical techniques were standardized and perfected over time, according to the report.
Many of the oldest skulls showed no evidence of bone healing following the operation, suggesting that the procedure was probably fatal.

The world's smallest radio frequency (RF) integrated circuit packaging solution has been claimed by Avago Technologies Ltd. (San Jose, Calif.)--a spin-off of Agilent Technologies (which was a spin-off of Hewlett Packard). Avago claims its WaferCap is the industry's first wafer-level chip-scale packaging (CSP) technology, squeezing RF chips into a 1-by-.5-by.25 millimeter leadless "0402"-size package, more familiar as the form factor for surface-mount technology (SMT) capacitors.

She has been named Beauty, though this eagle is anything but. Part of Beauty's beak was shot off several years ago, leaving her with a stump that is useless for hunting food. A team of volunteers is working to attach an artificial beak to the disfigured bird, in an effort to keep her alive.
"For Beauty it's like using only one chopstick to eat. It can't be done" said biologist Jane Fink Cantwell, who operates a raptor recovery center in this Idaho Panhandle town. "She has trouble drinking. She can't preen her feathers. That's all about to change."
Scientists have created what is believed to be the first genetically modified (GM) human embryo.
A team from Cornell University in New York produced the GM embryo to study how early cells and diseases develop. It was destroyed after five days.

Europe's newest observatory has opened in one of the darkest corners of the UK.
With almost no light pollution from surrounding settlements the Kielder Observatory has breathtaking views of the night sky, according to the astronomers associated with the building.
It has been built in a remote part of the vast Kielder Water and Forest Park in Northumberland.

Ancient myths suggest that a giant comet may have visited the Earth a few thousand years ago, raining fireballs and meteors
Scientists are starting to recognise that the evolution of life on Earth has been affected, if not largely shaped, by its celestial environment. We now recognise that throughout its history the Earth has been bombarded by comets, small asteroids, meteorites (small rocky or iron bodies) and smaller particle and dust (meteor) showers. Over the years, astronomers have detected a substantial population of such small bodies out there in the Solar System, confirming that the threat of their impact with the Earth is a significant one. Current estimates, for example, suggest that between 10 and 30 impacts similar to the one that occurred in Tunguska in Siberia in 1908 have happened over recorded history, with perhaps one or more exploding with a force equivalent to that produced by 500 to 1000 megatonnes of TNT.

We've all heard of Pavlov's dogs, the famous canines trained by Russian physiologist Ivan Pavlov to associate food with the sound of a bell. Now, scientists have found that bacteria may be capable of similar behavior--an ability never seen in such simple organisms.
Researchers already know that microbes can mount simple responses to changes in their environment, such as acidity fluctuations, by altering their internal workings. If the changes are regular enough, bacteria can respond ahead of time. But systems biologist Saeed Tavazoie of Princeton University wondered if microbes were capable of more sophisticated reasoning. Could they, for example, learn to match a signal that didn't occur regularly to a probable future event? If so, the bacterium could improve its chances of survival by turning on a preemptive response to that event.
