Ethnologisches Foto-Archiv im Internet
Das einzigartige Bildarchiv der Basler Mission ist künftig weltweit via Internet frei zugänglich. Auf der Webseite können rund 28.000 historische Aufnahmen heruntergeladen werden. Die Missionare der Basler Mission (heute Mission 21) waren schon um 1860 mit dem Fotoapparat unterwegs und dokumentierten das Leben in Afrika und Asien. Bis 1950 kamen rund 50.000 Aufnahmen zusammen, von denen bisher 28.400 mikroverfilmt, inventarisiert, konserviert und beschrieben wurden, wie es an einer Medienkonferenz am Freitag in Basel hieß.

2.000 Jahre alte Straße südlich von Rom entdeckt
Eine mehr als 2.000 Jahre alte römische Straße ist bei Bauarbeiten für eine neue Bahnstrecke östlich von Rom entdeckt worden. Die Bagger seien auf einen 160 Meter langen und zweieinhalb Meter breiten Abschnitt der Via Collatina gestoßen, die einst parallel zur Via Tiburtina verlief.

Holograms in Motion
The newest 3-D video displays herald an interactive future for imaging.
A half-meter-long protein floats in midair, several centimeters in front of a monitor. It looks like an oversize curled ribbon from a birthday package. As three molecular biologists maneuver around the image, studying the complex molecule from different angles, it begins to fold, slowly twisting and interlocking into a tangled knot. Its shape is a clue to the function it performs in the human body: some proteins produce chemical reactions or behave like a kind of scaffolding for cells, while others help with cell division. Creation of a drug that encourages or blocks a protein’s action—say, preventing cancerous cells from dividing—could lead to more effective treatments. One of the researchers uses a stylus to prod the protein at several points. As she does so, the protein refolds itself, revealing a location that could be targeted with a drug to inhibit the protein’s function.

X-Ray Vision for G.I. Joe
The US Army can see through walls.
Point the SoldierVision unit from Time Domain at a wall, for example, "and what you see is an outline of the room behind, with people showing up as yellow blobs," explains Ralph Petroff, CEO of the Huntsville (Ala.) UWB pioneer. The system is designed to focus on "large bags of salty water, which is what humans are," he adds. But metallic objects, such as guns, show up as blue. So a yellow blob with a blue streak "could be cause for concern," says Petroff.

Ray of Light for the Blind
Computerized, brain-implanted eyewear could be the answer to seeing again. Jens is able to see through inventive technology from New York's Dobelle Institute, which produces a form of artificial vision. See how this revolutionary piece of eyewear works. It's not perfect, but it's enough for Jens to drive a car around a parking lot.

Kilimanjaro Snow Cap May Melt Soon
The snow cap of Mount Kilimanjaro, famed in literature and beloved by tourists, first formed some 11,000 years ago, but will be gone in two decades, according to researchers who say the ice fields on Africa's highest mountain shrank by 80 percent in the past century.

Tear-free onion could be on the menu
It's as certain as death and taxes. Chopping onions makes people cry. Now scientists in Japan say they may have discovered a way to dry the tears without taking away any of the taste.

Walk This Way
Researchers at the Georgia Tech Research Institute are working on ways to identify people by the way they walk. Go ahead and wear a mask to your bank heist--a lot of good it'll do you if a new federally funded research project pays off.

Stone skimming formula adds new spin
Everyone knows a stone bounces best on water if it is round and flat, and spun towards the water as fast as possible. Some enthusiasts even travel to international stone-skimming competitions, like world champion Jerdone Coleman-McGhee, who made a stone bounce 38 times on Blanco River, Texas, in 1992.

Scientists Confirm Massive Black Hole in Milky Way
Scientists said Wednesday they have discovered at the center of our galaxy a huge black hole, a mysterious celestial object that sucks in everything around it including light.
By observing the orbit of a star around the invisible gravitational field, an international team of scientists has eliminated other possibilities of explaining the phenomenon. "It is a great step forward," Dr. Reinhard Genzel, of the Max-Planck Institute for Extraterrestrial Physics near Munich who led the team, told Reuters Wednesday.

Laser could scan skies for black holes
Astronomers could scan the skies for black holes using a super-powerful laser, two physicists are suggesting1. Black holes close to our Solar System would reflect the light back to Earth, the pair calculates, despite the popular image of these holes as omnivorous astrophysical objects from which not even light can escape.

Etruskisches Handwerkerviertel in der Toskana entdeckt
Italienische Archäologen haben in der Toskana ein etruskisches Handwerkerviertel entdeckt. In Petriolo bei Siena seien viele wertvolle Objekte aus Eisen, Bronze und Ton gefunden worden, berichteten italienische Medien am Dienstag. Die Gegenstände zeugten von einer blühenden Schaffensperiode im 7. und 6. Jahrhundert v. Chr. in dieser Gegend.
