UA researchers and collaborators have turned their attention to lateral force transfer, to design buildings that can better withstand seismic forces.

An award-winning team of researchers at the University of Arizona and partnering universities is working to develop buildings that will not collapse under the force of major earthquakes, such as last year’s 7.1-magnitude quake in central Mexico and 7.3-magnitude quake near the Iran-Iraq border. The two earthquakes were the deadliest of 2017, killing approximately 900 people combined, flattening hundreds of buildings and leaving tens of thousands of people homeless. (more…)

At UD, engineering students are making next-generation consumer products

When a Maryland-based boat kit company wanted help designing a component that rowers sit in, they contacted a University of Delaware engineer with ideal expertise. Jenni Buckley, an associate professor of mechanical engineering and a rower in the UD Athletics Hall of Fame, advises students in Senior Design, a one-semester capstone engineering design program.

Surprise: A virus-like protein is important for cognition and memory

By Guest PostJuly 12, 2018Scienceelissa pastuzyn. viral capsid, history of arc, jason shepherd, virus like protein

A protein involved in cognition and storing long-term memories looks and acts like a protein from viruses. The protein, called Arc, has properties similar to those that viruses use for infecting host cells, and originated from a chance evolutionary event that occurred hundreds of millions of years ago.

Locker oder fest: Wenn Knoten auf Polymerringen sitzen

By Guest PostJuly 9, 2018Sciencechristos likos, knoten auf polymerringen, marisol ripoll, maximilian liebetreu, ring topologie

Knoten begegnen uns täglich im Alltag. In der Natur finden sich Knoten regelmäßig auf Polymeren, also auf chemischen Verbindungen, die aus Ketten oder verzweigten Molekülen bestehen. Polymere sind von größter Wichtigkeit in der Biologie – Stichwort DNA –, aber genauso relevant für die Entwicklung von Kunststoffen oder anderen Materialien in der Chemie und Materialforschung.

The development of ultra-intense lasers delivering the same power as the entire U.S. power grid has enabled the study of cosmic phenomena such as supernovae and black holes in earthbound laboratories. Now, a new method developed by computational astrophysicists at the University of Chicago allows scientists to analyze a key characteristic of these events: their powerful and complex magnetic fields.

Tübinger Astrophysiker an Weltraummission der ESA beteiligt: Satellit durchsucht Weltall nach leuchtstarken Ereignissen

Astrophysiker der Universität Tübingen sind an einem neuen Projekt der europäischen Raumfahrtagentur ESA beteiligt: Als eines von drei Konzepten wurde die Mission „THESEUS“, bei der das Institut für Astronomie und Astrophysik (IAAT) eine wichtige Rolle spielt, in das Wissenschaftsprogramm aufgenommen. Der Satellit könnte 2032 starten und soll das frühe Universum erkunden, insbesondere die ersten 1,5 Milliarden Jahre nach dem Urknall. (more…)

New Discovery Could Improve Organic Solar Cell Performance

Science team at Berkeley Lab-based DOE science center unravels the mystery of a multiplier mechanism in an organic crystal

While there is a growing market for organic solar cells – they contain materials that are cheaper, more abundant, and more environmentally friendly than those used in typical solar panels – they also tend to be less efficient in converting sunlight to electricity than conventional solar cells.
