Interdisciplinary Research

Recent conclusions that the storied Vinland Map is merely a clever forgery are based on a flawed understanding of the evidence, according to a scientist at the Smithsonian Institution. Results from last year’s study debunking the map’s authenticity can also be construed to boost the validity of its medieval origins, the scientist claims.

The report will appear in the Dec. 1 edition of Analytical Chemistry, a peer-reviewed journal of the American Chemical Society, the world’s largest scient

When amazing new computers and other electronic devices emerge, they will have been conceived and incubated in university laboratories like that of Dr. Chris Gorman, professor of chemistry at North Carolina State University. There, the scientist and his multidisciplinary team are working to build, molecule by molecule, a nanoscale transistor.

That’s an electronic switch so small it can only be seen with a high-tech device called a scanning tunneling microscope. And if you go to the library t

More than 150 researchers from across Europe, Canada, the United States, China and as far away as Chile have come together to recount their many and varied uses of a single instrument – a desk-sized camera called MERIS, hurtling through space aboard Envisat at more than seven kilometres per second.

The Medium Resolution Imaging Spectrometer (MERIS) is one of ten sensors on Envisat, looking down from the earthward face of the spacecraft. It works by recording visible and near-infrared radiati

Recent evidence suggests that oxygen levels were suppressed worldwide 175 million to 275 million years ago and fell to precipitously low levels compared with today’s atmosphere, low enough to make breathing the air at sea level feel like respiration at high altitude.

Now, a University of Washington paleontologist theorizes that low oxygen and repeated short but substantial temperature increases because of greenhouse warming sparked two major mass-extinction events, one of which eradicated

First use of disordered nanowires, organic molecules as programmable memory

Chemists at Rice University have demonstrated that disordered assemblies of gold nanowires and conductive organic molecules can function as non-volatile memory, one of the key components of computer chips.

“A large part of the cost associated with creating integrated circuits comes from the painstaking precision required to ensure that each of the millions of circuits on the chip are placed in exactl

Zero-G flying is just like throwing a football through the air, explains test pilot Captain Gilles Le Barzic as he briefs an audience about to leave gravity behind: “Except instead of a ball we have an aircraft.”

Le Barzic is one of three expert pilots on ESA’s A-300 ’Zero-G’ Airbus, billed by its operator Novespace as ’the plane that removes gravity’. The aircraft has been specially strengthened to fly parabolic arcs enabling researchers to carry out experiments in weightlessness without
