When Kathryn Bard reached through the small hole that opened in a hillside along Egypts Red Sea coast, her hand touched nearly 4,000 years of history.
The opening that Bard, an associate professor of archaeology at Boston University, and her teams co-leader Rodolfo Fattovich, a professor of archaeology at Italys University of Naples "LOrientale," discovered was the entrance to a large, man-made cave. Two days later at a site about 30 meters beyond this cave, the team removed sand covering the entrance to a second cave, one that held the well-preserved cedar timbers of an ancient Egyptian sea-faring vessel.
The timbers, together with limestone block-anchors, curved cedar steering oars, rigging ropes, and other items, are from ancient Egyptian ships. In addition to the nautical items in the second cave, and the two antechambers discovered to branch from it, the archaeologists found limestone tablets with hieroglyphic inscriptions that detail long-ago trade expeditions to the Red Sea region known as Punt.

World first experiments on sensor that may revolutionise everything from medical devices to unmanned vehicles
The new sensor - capable of detecting vibrations of living cells - may revolutionise everything from medical devices to unmanned vehicles.
Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
