Berkeley Lab framework supports research into lifelike behavior of inanimate objects
An elegantly simple experiment with floating particles self-assembling in response to sound waves has provided a new framework for studying how seemingly lifelike behaviors emerge in response to external forces. (more…)
Der anregend wirkende Bitterstoff Koffein kann die Freisetzung von Salzsäure im Magen sowohl stimulieren als auch verzögern, je nachdem, ob er Bitterrezeptoren im Magen oder im Mund aktiviert. “Wie unsere Ergebnisse zeigen, spielen Bitterrezeptoren generell eine Rolle bei der Regulation der Magensäureausschüttung. Es wäre daher denkbar, dass sich Bitterstoffe oder Bitterblocker zukünftig als Therapeutika einsetzen ließen, um eine Übersäuerung des Magens zu behandeln”, sagt Studienleiterin Veronika Somoza von der Universität Wien.

When HIV/AIDS became a pandemic, epidemiologists wanted to know where it began. In the 1980s, they found their answer in a freezer filled with blood. This blood had been collected in the 1950s from members of indigenous communities in Africa as part of anthropological research on human variation. To this day, that sample is the oldest trace of HIV known to biomedicine. It is what launched Joanna Radin’s interest in the field of biobanking, a means of preserving blood and other tissues for future research. It is also what led her to write her recently published book, “Life on Ice: A History of New Uses for Cold Blood.” (more…)
COLUMBIA, Mo. – The skulls of alligators protect their brains, eyes and sense organs while producing some of the most powerful bite forces in the animal kingdom. The ability to bite hard is critical for crocodilians to eat their food such as turtles, wildebeest and other large prey; therefore, their anatomy is closely studied by veterinarians and paleontologists who are interested in animal movements and anatomy.

A video camera captures an interview with a man named Spirit, who relaxes in an outdoor plaza on a sunny afternoon. Of his nearby service dogs, Kyya and Miniaga, he says, “They mean everything to me, and I mean everything to them.” (more…)
IBM plans to make a 10-Year, $240 Million Investment in new lab with MIT to advance AI hardware and software and algorithms
Cambridge, MA – 07 Sep 2017: IBM (NYSE: IBM) and MIT today announced that IBM plans to make a 10-year, $240 million investment to create the MIT–IBM Watson AI Lab in partnership with MIT. The lab will carry out fundamental artificial intelligence (AI) research and seek to propel scientific breakthroughs that unlock the potential of AI. The collaboration aims to advance AI hardware, software and algorithms related to deep learning and other areas, increase AI’s impact on industries, such as health care and cybersecurity, and explore the economic and ethical implications of AI on society. IBM’s $240 million investment in the lab will support research by IBM and MIT scientists. (more…)
Freiburger Biochemiker klären Struktur von Carotinoid-lieferndem Enzym auf
Die Unterversorgung mit Vitamin A in Nahrungsmitteln bedingt weltweit gesundheitliche Probleme, die zu Erblindung oder gar zum Tod führen können. Betroffen sind in Schwellen- und Drittwelt-Ländern vor allem Kinder, die aufgrund von Mangelernährung zu wenig Vitamin A oder dessen Vorstufe Beta-Carotin zu sich nehmen. Carotinoide sorgen auch für die markante Farbe der namensgebenden Karotten oder der Süßkartoffel, weswegen Beta-Carotin von der Lebensmittelindustrie als Lebensmittelfarbe E160 gerne zur Farbgestaltung von Softdrinks, Joghurts und anderen Nahrungsmitteln verwendet wird.

The technology of solar energy has progressed dramatically in the last few decades, as it operates with increasing efficiency and at lower costs.
But the matter of how solar panels look remains an obstacle. Most photovoltaic panels are blue or black and cover large portions of buildings with a monotone hue. That might not jibe with your personal taste – or that of your homeowners’ association. It’s a limitation that has hindered the integration of solar energy into some commercial applications. In fact, architects and designers have long requested a wider choice of colors for solar cells to allow them to seamlessly blend into a building’s façade or an electronic system. (more…)
