UD scientists sleuth out proteins involved in Crohn’s disease
University of Delaware researchers have identified a protein, hiding in plain sight, that acts like a bodyguard to help protect and stabilize another key protein, that when unstable, is involved in Crohn’s disease. The fundamental research points to a possible pathway for developing an effective therapy for the inflammatory bowel disease. (more…)
Impact glass stores biodata for millions of years
Bits of plant life encapsulated in molten glass by asteroid and comet impacts millions of years ago give geologists information about climate and life forms on the ancient Earth. Scientists exploring large fields of impact glass in Argentina suggest that what happened on Earth might well have happened on Mars millions of years ago. Martian impact glass could hold traces of organic compounds. (more…)
Glanz und Glitzer scheinen bereits vor 10.000 Jahren eine große Anziehungskraft gehabt zu haben. Prof. Walter Leitner und sein Team vom Institut für Archäologien der Universität Innsbruck konnten eine prähistorische Abbaustelle für Bergkristall in den Tuxer Alpen nachweisen und ermöglichen Einblicke in das steinzeitliche Leben Tirols.
Die Forschungsarbeit an der mit 2800 Metern höchstgelegenen archäologischen Fundstelle Österreichs ist beschwerlich. Mehrere Stunden Fußmarsch sind nötig, um das so genannte Riepenkar am Südfuß des Berges Olperer zu erreichen. Die instabile Wetterlage in dieser hochalpinen Gegend macht archäologische Sondagen nur an wenigen Tagen des Jahres überhaupt erst möglich. Das aus der Quarzkluft abgetragene Gesteinsmaterial wird in bis zu 25 Kilo schweren Rucksäcken ins Tal getragen. „Die Mühe lohnt sich aber allemal“, freut sich Walter Leitner über seine Entdeckungen. Durch Hinweise des Zillertaler Mineraliensammlers Walter Ungerank wurde der Archäologe auf die Stelle aufmerksam und begann mit Untersuchungen vor Ort. (more…)
The widespread disappearance of stromatolites, the earliest visible manifestation of life on Earth, may have been driven by single-celled organisms called foraminifera.
The findings, by scientists at Woods Hole Oceanographic Institution (WHOI); Massachusetts Institute of Technology; the University of Connecticut; Harvard Medical School; and Beth Israel Deaconess Medical Center, Boston, were published online the week of May 27 in the Proceedings of the National Academy of Sciences.

Ridges in impact craters on Mars appear to be fossils of cracks in the Martian surface, formed by minerals deposited by flowing water. Water flowing beneath the surface suggests life may once have been possible on Mars.
PROVIDENCE, R.I. [Brown University] — Networks of narrow ridges found in impact craters on Mars appear to be the fossilized remnants of underground cracks through which water once flowed, according to a new analysis by researchers from Brown University.
The study, in press in the journal Geophysical Research Letters, bolsters the idea that the subsurface environment on Mars once had an active hydrology and could be a good place to search for evidence of past life. The research was conducted by Lee Saper, a recent Brown graduate, with Jack Mustard, professor of geological sciences. (more…)
By using common materials found pretty much anywhere there is dirt, a team of Michigan State University researchers have developed a new thermoelectric material.
This is important, they said, because the vast majority of heat that is generated from, for example, a car engine, is lost through the tail pipe. It’s the thermoelectric material’s job to take that heat and turn it into something useful, like electricity. (more…)
UA undergraduate researcher Ersilia Anghel has been collecting artistic photographs of minerals, plants, animals and humans, illustrating the intersections between the arts and sciences.
Scientists and artists have long collaborated to produce illustrative images and paintings of medical procedures, human anatomy and botanical displays.
But with the emergence of new, advanced technologies, scientists have begun to more readily produce their own photographic works, often times revealing the aesthetics of another world around us. (more…)
*Discovery may lead to novel biotech and nanotech uses*
Nevada, the “Silver State,” is well-known for mining precious metals.
But scientists Dennis Bazylinski and colleagues at the University of Nevada Las Vegas (UNLV) do a different type of mining.
They sluice through every water body they can find, looking for new forms of microbial magnetism.
In a basin named Badwater on the edge of Death Valley National Park, Bazylinski and researcher Christopher Lefèvre hit pay dirt. (more…)
