Findings are a major step toward understanding persistent infections that affect people with cystic fibrosis

Led by scientists at UCLA, an international team of researchers has discovered that bacteria have a “memory” that passes sensory knowledge from one generation of cells to the next, all without a central nervous system or any neurons. (more…)

Tierphysiologen der Universität Tübingen identifizieren Gedächtniszellen, mit denen Rabenvögel Gesehenes im Arbeitsgedächtnis speichern – ganz ohne Großhirnrinde

Ein gut funktionierendes Arbeitsgedächtnis für die kurzfristige Speicherung und Verarbeitung von Informationen ist eine wichtige Grundlage der Intelligenz. Ohne Arbeitsgedächtnis als einer Art „geistigen Notizblock“ könnten wir keiner Unterhaltung folgen, Kopfrechnen oder „Memory“ spielen. Im Tierreich sind Rabenvögel bekannt für ihre Schläue, denn sie besitzen ein gut funktionierendes Arbeitsgedächtnis. Doch überraschenderweise hat ihr ansehnlich entwickeltes, aber grundsätzlich anders aufgebautes Endhirn keine Großhirnrinde, die bei uns Menschen und anderen Säugetieren das Arbeitsgedächtnis hervorbringt. Wie gelingt es Rabenvögeln, wichtige Informationen im Gedächtnis zu behalten? (more…)

Teaching a Computer to Play ‘Concentration’ Advances Security, Understanding of the Human Mind

Computer science researchers have programmed a computer to play the game Concentration (also known as Memory). The work could help improve computer security – and improve our understanding of how the human mind works.

The researchers developed a program to get the software system called ACT-R, a computer simulation that attempts to replicate human thought processes, to play Concentration. In the game, multiple matching pairs of cards are placed face down in a random order, and players are asked to flip over two cards, one at a time, to find the matching pairs. If a player flips over two cards that do not match, the cards are placed back face down. The player succeeds by remembering where the matching cards are located. (more…)

Bittersweet: Bait-Averse Cockroaches Shudder at Sugar

Sugar isn’t always sweet to German cockroaches, especially to the ones that avoid roach baits.

In a study published May 24 in the journal Science, North Carolina State University entomologists show the neural mechanism behind the aversion to glucose, the simple sugar that is a popular ingredient in roach-bait poison. Glucose sets off bitter receptors in roach taste buds, causing roaches to avoid foods that bring on this taste-bud reaction. This aversion has a genetic basis and it eventually spreads to offspring, resulting in increasingly large groups of cockroaches that reject glucose and any baits made with it.

In normal German cockroaches, glucose elicits activity in sugar gustatory receptor neurons, which react when exposed to sugars like glucose and fructose – components of corn syrup, a common roach-bait ingredient. Generally, roaches have a sweet tooth for these sugars. (more…)

Organic Ferroelectric Molecule Shows Promise for Memory Chips, Sensors

At the heart of computing are tiny crystals that transmit and store digital information’s ones and zeroes. Today these are hard and brittle materials. But cheap, flexible, nontoxic organic molecules may play a role in the future of hardware.

A team led by the University of Washington in Seattle and the Southeast University in China discovered a molecule that shows promise as an organic alternative to today’s silicon-based semiconductors. The findings, published this week in the journal Science, display properties that make it well suited to a wide range of applications in memory, sensing and low-cost energy storage. (more…)

Charles Wright, hailed as one of the leading American poets of his generation, has been named the winner of Yale’s 2013 Bollingen Prize for American Poetry.

The Bollingen Prize in American Poetry is among the most prestigious prizes given to American writers. Established by Paul Mellon in 1949, it is awarded biennially by the Yale University Library to an American poet for the best book published during the previous two years or for lifetime achievement in poetry. The prize includes a cash award of $150,000. (more…)
