Before the digital age, neuroscientists got their information in the library like the rest of us. But the explosion of neuroscience research has resulted in the publication of nearly 2 million papers — more data than any researcher can read and absorb in a lifetime.

Twenty-four faculty members from colleges and universities from around the country left the Yale campus on Aug. 1 with a new mission: to inspire their freshman and sophomore students to pursue scientific research, specifically by discovering new antibiotics from soil bacteria.
In a week-long workshop called “The Small World Initiative” and held at Kline Biology Tower, the teachers developed the tools to engage their students in real-life research projects with such life-saving potential. (more…)
From a sweet deal to the bitter end, there’s no accounting for taste. Descriptions of flavor are littered throughout our common sayings, and there’s a good reason for that. Food and flavor sensations are a key part of the human experience, and everyone knows what “bitter” feels and tastes like.
But what happens when a scientist tries to quantify taste? What, exactly, is flavor? What makes a food taste sweet, or salty, or even cooked? (more…)
UD professor, scholar document culture of Peruvian community
As the elders of a small hunter-gatherer community told the story of how their people came to be, University of Delaware assistant professor of art Jonathan Cox and Summer Scholar Sarah Driver sat and listened, intrigued by the tale.
Over the course of seven days, they learned firsthand about the Ese’eja (ess-a-eha) Nation, a community of three distinct villages living in the remote areas of Infierno, Palma Real and Sonene, Peru. (more…)
Researchers at JILA have for the first time used an atomic clock as a quantum simulator, mimicking the behavior of a different, more complex quantum system.
Atomic clocks now join a growing list of physical systems that can be used for modeling and perhaps eventually explaining the quantum mechanical behavior of exotic materials such as high-temperature superconductors, which conduct electricity without resistance. All but the smallest, most trivial quantum systems are too complicated to simulate on classical computers, hence the interest in quantum simulators. Sharing some of the features of experimental quantum computers—a hot research topic—quantum simulators are “special purpose” devices designed to provide insight into specific challenging problems.

ANN ARBOR — The remains of the earliest European fort in the interior of what is now the United States have been discovered by a team of archaeologists, providing new insight into the start of the U.S. colonial era and the all-too-human reasons spoiling Spanish dreams of gold and glory.
Spanish Captain Juan Pardo and his men built Fort San Juan in the foothills of the Appalachian Mountains in 1567, nearly 20 years before Sir Walter Raleigh’s “lost colony” at Roanoke and 40 years before the Jamestown settlement established England’s presence in the region. (more…)
Most of what scientists know of Jupiter’s moon Europa they have gleaned from a dozen or so close flybys from NASA’s Voyager 2 spacecraft in 1979 and NASA’s Galileo spacecraft in the mid-to-late 1990s. Even in these fleeting, paparazzi-like encounters, scientists have seen a fractured, ice-covered world with tantalizing signs of a liquid water ocean under its surface. Such an environment could potentially be a hospitable home for microbial life. But what if we got to land on Europa’s surface and conduct something along the lines of a more in-depth interview? What would scientists ask? A new study in the journal Astrobiology authored by a NASA-appointed science definition team lays out their consensus on the most important questions to address.
“If one day humans send a robotic lander to the surface of Europa, we need to know what to look for and what tools it should carry,” said Robert Pappalardo, the study’s lead author, based at NASA’s Jet Propulsion Laboratory, Pasadena, Calif. “There is still a lot of preparation that is needed before we could land on Europa, but studies like these will help us focus on the technologies required to get us there, and on the data needed to help us scout out possible landing locations. Europa is the most likely place in our solar system beyond Earth to have life today, and a landed mission would be the best way to search for signs of life.” (more…)
Berkeley Lab scientists image cell-to-cell connections between soil microbes
The next time your Facebook stream is filled with cat videos, think about Myxococcus xanthus.The single-cell soil bacterium also uses a social network. But forget silly distractions. M. xanthus relies on its connections to avoid getting eaten and to score its next meal.
That’s the latest insight from a team of Berkeley Lab scientists. Using several imaging techniques, they saw for the first time that M. xanthus cells are connected by a network of chain-like membranes. (more…)
